    Full text : Considering all types of risks (technical, operational, natural hazards (e.g. geo-hazards) and third party intrusion), the underground pipelines constructed in accordance with the international standards are the most safe and reliable system for oil transportation. Statistical data provided by CONCAWE and US Department of Transportation confirms that the pipeline related spills are rare and mainly related to the old pipelines. Georgia's experience yet confirms the general sound guess that the situation in our countries is not the same as in western Europe or USA and accordingly the CONCAWE statistical data can not be applied mechanically. Two spills (although small and manageable), during the recent 4 years and some discovered illegal hot-taps on the Baku-Supsa pipeline indicate that the issue of third party intrusion risks is much higher in the region and well organized security system is required to protect the pipeline from intentional damage. Of course the pipeline system can not function isolated and it is integrated with the other systems of oil transportation, mainly with off-shore terminals and tankers. The most significant of the recorded pollution damages are related to the tanker collisions (like Prestige and Exxon Valdez cases). The basic fact, which we would like to stress, is that the environmental risks related to the tanker collisions are much higher for such confined or semi-confined systems as Black and Caspian seas. The overloading of the Black Sea transportation capacity and especially its limiting narrow point - the Bosporus will inevitably lead in future to the implementation of the restrictive measures limiting transportation of oil by tankers in the Black Sea. Therefore, the role of the BTC pipeline as major transportation system will increase significantly. We consider that responsibility of the scientific society is to facilitate this process as soon as the BTC pipeline is functional. The railway transportation of oil is quite

    Biomass-based energy and fuels are receiving attention because they are considered carbon neutral; i.e. the amount of CO(2) released during combustion of this biomass is nearly the same as that taken up by the plants during their growth. Bio-oil is a dark viscous liquid consisting of hydrocarbons. These are produced by fast pyrolysis of biomass. "As-is" biomass material has a low energy density (MJ m(-3)), hence, the cost of transporting this energy is high. Bio-oil has a high energy density as compared to "as-is" biomass material, consequently it helps in reducing the cost of energy transport. This study compares the life cycle assessment of transportation of bio-oil by pipeline with that by truck. The scope of the work includes the transportation of bio-oil by truck or pipeline from a centralized plant (supplied with forest biomass) to an end-user. Two cases are studied for pipeline transport of bio-oil: the first case considers a coal-based electricity supply for pumping the bio-oil through a pipeline; the second case considers an electricity supply from a renewable resource. The two cases of pipeline transport are compared to two cases of truck transport (truck trailer and super B-train truck). The life cycle greenhouse gas (GHG) emissions from the pipeline transport of bio-oil for the two cases of electricity supply are 345 and 17 g of CO(2) m(-3) km(-1), respectively. Similar values for transport by trailer (capacity - 30 m(3)) and super B-train truck (capacity - 60 m(3)) are 89 and 60 g of CO(2) m(-3) km(-1), respectively. Energy input for bio-oil transport is 3.95 MJ m(-3) km(-1) by pipeline, 2.59 MJ m(-3) km(-1) by truck and 1.66 MJ m(-3) km(-1) by super B-train truck. The results show that GHG emissions in pipeline transport are largely dependent on the source of electricity (higher for coal-based electricity). Substituting 250 m(3) day(-1) of pipeline-transported bio-oil for coal-based electricity can mitigate about 5.1 million tonnes of CO(2) per year

    The results of this applied research contribute fundamental elements for handling paraffinic crude oils (pipeline design and operation) and the optimization of the use of Pour Point Depressor additives. The rheological studies support the fluid-dynamic analyses that accurately predict the pipeline transport operation, unlike traditional parameters such as pour point and cloud point. Evaluations of rheological behavior was carried out at the laboratory level in concentric viscometers and were scaled at the pilot plant level in a fluid-dynamic test circuit in pipes with diameters from 1.27 to 15.24 cm (1/2 to 6 inches), where the laboratory scale was confirmed. The tests were performed under strain rate temperature and conditions similar to those of pipeline and flow line operation in production fields. Also, the viability to restart pumping after a prolonged shutdown with extreme temperatures was calculated, evaluating creep stress. The study has allowed us to transport Cupiagua crude oil without the PPD additive in a segregated manner, showing that despite its high pour point 300K (27 grades Celsius), in dynamic conditions similar to those in the pipeline, the crude oil flows at temperatures near 283K (10 Celsius degrades) without putting the integrity of the pipe in danger and within operational and equipment restrictions for the company operating the pipeline. This has generated significant savings, due to the additive as well as the possibility to segregate the crude oils, which facilitates the operation of the paraffin plant at the Barrancabermeja Industrial Complex

  5. A NEW TECHNIQUE OF OIL TRANSPORTATION IN PIPELINE BY STEAM INJECTION

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The direct contact heating of crude oil with steam is promising technique for improving crude oil transportation in pipelines. Crude oil temperature is increased greatly by a small quantity of steam due to the high steam latent heat and direct contact heat transfer. A jet pump was developed for injecting steam into oil in order to get a high efficiency by transferring momentum and energy from a high-velocity jet to ambient fluid. The jet pump was designed based on the free injection principle, which has no rotation parts and no converging mixing chamber, therefore it would not be blocked by the viscous crude oil. The technical feasibility of this method has been tested in the Liaohe Oilfeld, China.

    Full Text Available With the increasing demand of oil products in China, the energy consumption of pipeline operation will continue to rise greatly, as well as the cost of oil transportation. In the field of practical engineering, saving energy, reducing energy consumption and adapting to the international oil situation are the development trends and represent difficult problems. Based on the basic principle of non-equilibrium thermodynamics, this paper derives the field equilibrium equations of non-equilibrium thermodynamic process for pipeline transportation. To seek the bilinear form of “force” and “flow” in the non-equilibrium thermodynamics of entropy generation rate, the oil pipeline exergy balance equation and the exergy transfer pipeline dynamic equation of the irreversibility were established. The exergy balance equation was applied to energy balance evaluation system, which makes the system more perfect. The exergy flow transfer law of the waxy oil pipeline were explored deeply from the directions of dynamic exergy, pressure exergy, thermal exergy and diffusion exergy. Taking an oil pipeline as an example, the influence factors of exergy transfer coefficient and exergy flow density were analyzed separately.

  10. Canadian pipeline transportation system : transportation assessment

    2009-07-01

    In addition to regulating the construction and operation of 70,000 km of oil and natural gas pipelines in Canada, the National Energy Board (NEB) regulates the trade of natural gas, oil and natural gas liquids. This report provided an assessment of the Canadian hydrocarbon transportation system in relation to its ability to provide a robust energy infrastructure. Data was collected from NEB-regulated pipeline companies and a range of publicly available sources to determine if adequate pipeline capacity is in place to transport products to consumers. The NEB also used throughput and capacity information received from pipeline operators as well as members of the investment community. The study examined price differentials compared with firm service tolls for transportation paths, as well as capacity utilization on pipelines and the degree of apportionment on major oil pipelines. This review indicated that in general, the Canadian pipeline transportation system continues to work effectively, with adequate pipeline capacity in place to move products to consumers who need them. 9 tabs., 30 figs., 3 appendices.

    Liquid pipeline codes generally stipulate placement of block valves along liquid transmission pipelines such as on each side of major river crossings where environmental hazards could cause or are foreseen to potentially cause serious consequences. Codes, however, do not stipulate any requirement for block valve spacing for low vapour pressure petroleum transportation, nor for remote pipeline valve operations to reduce spills. A review of pipeline codes for valve requirement and spill limitation in high consequence areas is thus presented along with a criteria for an acceptable spill volume that could be caused by pipeline leak/full rupture. A technique for deciding economically and technically effective pipeline block valve automation for remote operation to reduce oil spilled and control of hazards is also provided. In this review, industry practice is highlighted and application of the criteria for maximum permissible oil spill and the technique for deciding valve automation thus developed, as applied to ORSUB pipeline is presented. ORSUB is one of the three initially selected pipelines that have been studied. These pipelines represent about 14% of the total length of petroleum transmission lines operated by PETROBRAS Transporte S.A. (TRANSPETRO) in Brazil. Based on the implementation of valve motorization on these three pipeline, motorization of block valves for remote operation on the remaining pipelines is intended, depending on the success of these implementations, on historical records of failure and appropriate ranking.

  12. Study on the Effect of Reciprocating Pump Pipeline System Vibration on Oil Transportation Stations

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Due to the periodic movement of the piston in the reciprocating pump, the fluid will cause a pressure pulsation, and the resulting pipeline vibration may lead to instrument distortion, pipe failure and equipment damage. Therefore, it is necessary to study the vibration phenomena of reciprocating pump pipelines based on pressure pulsation theory. This paper starts from the reciprocating pump pipe pressure pulsation caused by a fluid, pressure pulsation in the pipeline and the unbalanced exciting force is calculated under the action of the reciprocating pump. Then, the numerical simulation model is established based on the pipe beam model, and the rationality of the numerical simulation method is verified by indoor experiments. Finally, a case study is taken as an example to analyze the vibration law of the pipeline system, and vibration reduction measures are proposed. The following main conclusions are drawn from the analysis: (1 unbalanced exciting forces are produced in the elbows or tee joints, and it can also influence the straight pipe to different levels; (2 in actual engineering, it should be possible to prevent the simultaneous settlement of multiple places; (3 the vibration amplitude increases with the pipe thermal stress, and when the oil temperature is higher than 85 °C, it had a greater influence on the vertical vibration amplitude of the pipe.

    1979-01-01

    Pipelines are the leading bulk commodity transporter and should play an even more important role in the future of energy transportation and distribution. As fossil fuel and low-cost uranium resources become depleted, it will be economical to produce hydrogen by electrolysis and transport it through underground pipelines to points of consumption. The cost would be only two to three times that of transporting natural gas per unit of heat energy and substantially less than the cost of transporting electric energy in overhead, extra-high-voltage transmission lines. Pipeline design, including economic pipe diameter; pipe material; operation by remote control and automation; cathodic protection; pipeline construction; and pipeline maintenance, particularly as regards the 1157 km long Oil India Pipeline, are discussed.

    Knolle, Ernst G.

    1994-01-01

    This maglev crude oil pipeline consists of two conduits guiding an endless stream of long containers. One conduit carries loaded containers and the other empty returns. The containers are levitated by permanent magnets in repulsion and propelled by stationary linear induction motors. The containers are linked to each other in a manner that allows them, while in continuous motion, to be folded into side by side position at loading and unloading points. This folding causes a speed reduction in proportion to the ratio of container diameter to container length. While in side by side position, containers are opened at their ends to be filled or emptied. Container size and speed are elected to produce a desired carrying capacity.

    This paper presents the work developed on a pipeline network that transports oil derivatives. The transport occurs in batches of a specific product, each one having a defined route: the pumping origin, a destination for its receipt and the pipelines which the product is moved through. The network studied has a total of thirty pipelines connected by fourteen possible areas of pumping and/or receiving, this makes it not trivial to obtain the batches order in the pipeline. In order to obtain the passage of batches ordered list in the pipeline network, was developed an algorithm capable of propagating a batches list that only have route, start time and end time of pumping in the origin. This algorithm is part of a larger project whose goal is to obtain a tool to aid the process of operational decision making in a real pipeline network. The developed module can also generate the entry and exit times of each batch for each pipe through which it passes. With this information, analysis and/or validations can be made. At the end of the process, the result is a list of all the pumped batches in all pipes where it must go by. Thus, it is made a small pos-processing where the list is sorted, first by pipeline and then by start time of entry into the duct, which naturally causes the passage of the batches list in the ducts to be obtained. This work is based on the development presented by Czaikowski et al (2008). (author)

    2007-01-01

    We address the valve location problem, one of the basic problems in design of long oil pipelines. Whenever a pipeline is depressurized, the shutoff valves block the oil flow and seal the damaged part of the pipeline. Thus, the quantity of oil possibly contaminating the area around the pipeline is determined by the volume of the damaged section of the pipeline between two consecutive valves. Then, ecologic damage can be quantified by the amount of leaked oil and the environmental characteristi...

  18. Crude oil pipeline expansion summary

    International Nuclear Information System (INIS)

    2005-02-01

    The Canadian Association of Petroleum Producers has been working with producers to address issues associated with the development of new pipeline capacity from western Canada. This document presents an assessment of the need for additional oil pipeline capacity given the changing mix of crude oil types and forecasted supply growth. It is of particular interest to crude oil producers and contributes to current available information for market participants. While detailed, the underlying analysis does not account for all the factors that may come into play when individual market participants make choices about which expansions they may support. The key focus is on the importance of timely expansion. It was emphasized that if pipeline expansions lags the crude supply growth, then the consequences would be both significant and unacceptable. Obstacles to timely expansion are also discussed. The report reviews the production and supply forecasts, the existing crude oil pipeline infrastructure, opportunities for new market development, requirements for new pipeline capacity and tolling options for pipeline development. tabs., figs., 1 appendix

    Nord-West Oelleitung (NWO) operates 2 crude oil pipelines from Wilhemshaven to Koln and Hamburg respectively. German regulations for transporting flammable substances stipulate that 2 independent continuously working procedures be used to detect leaks. Leak detection pigs are used routinely to complement the surveillance system. This paper described the specific issues of transient leak detection in crude oil pipelines. It was noted that traditional methods have failed to detect leaks that occur immediately after pumps are turned on or off because the pressure wave generated by the transient dominates the pressure wave that results from the leak. Frequent operational changes in a pipeline are often accompanied by an increased number of false alarms and failure to detect leaks due to unsteady operations. NWO therefore decided to have the Atmos statistical pipeline leak detection (SPLD) system installed on their pipelines. The key to the SPLD system is the sequential probability ratio test. Comprehensive data validation is performed following reception of pipeline data from the supervisory control and data acquisition (SCADA) system. The validated data is then used to calculate the corrected flow imbalance, which is fed into the SPRT to determine if there is an increase in the flow imbalance. Pattern recognition is then used to distinguish a leak from operational changes. The SPLD is unique because it uses 3 computational pipeline monitoring methods simultaneously, namely modified volume balance, statistical analysis, and pressure and flow monitoring. The successful installation and testing of the SPLD in 2 crude oil pipelines was described along with the main difficulties associated with transient leaks. Field results were presented for both steady-state and transient conditions. 5 refs., 2 tabs., 16 figs.

  2. Pipeline capacity and heavy oil markets

    International Nuclear Information System (INIS)

    Scott, G.R.

    1993-01-01

    Aspects of transporting heavy crude to markets from Canadian sources are discussed, with reference to pipeline expansion, western Canadian crude supply, and exports to various Petroleum Administration for Defense Districts (PADDs) in the USA. Pipeline expansions have been proposed by Interprovincial Pipeline, Trans Mountain Pipeline, Rangeland, and Wascana, and some of these proposals are in the review stage. Western Canadian crude supply is expected to peak at 1.9 million bbl/d in 1996. An increase in heavy crude supply is expected but this increase will not be sufficient to offset a decline in light crude supply. Adequate pipeline capacity should exist with the Interprovincial expansion volume of 170,000 bbl/d and the Trans Mountain expansion of 38,000 bbl/d forecast to be in place by 1995. Canadian crude exports to the USA have steadily increased since 1989, and heavy crude exports have grown an average of 20,000 bbl/d each year. In PADD Region IV, oil production is declining and ca 20,000 bbl/d of heavy crude will be needed by the year 2000; additional pipeline capacity will be required. In PADD Region II, Canadian heavy crude imports are ca 390,000 bbl/d and further market opportunities exist, after the Interprovincial expansion is complete. When the various combinations of possible pipeline expansions or reversals are considered, a range of heavy crude near-term growth potentials is obtained in which Canadian heavy oil would displace offshore heavy oil supplied to USA refineries. This potential is seen to range from 35,000 bbl/d to 200,000 bbl/d. 7 refs., 20 figs., 3 tabs

    The pipeline transportation applying risks assessment issue in the arctic conditions is addressed in the paper. Pipeline quality characteristics in the given environment has been assessed. To achieve the stated objective, the pipelines mathematical model was designed and visualized by using the software product SOLIDWORKS. When developing the mathematical model the obtained results made possible to define the pipeline optimal characteristics for designing on the Arctic sea bottom. In the course of conducting the research the pipe avalanche collapse risks were examined, internal longitudinal and circular loads acting on the pipeline were analyzed, as well as the water impact hydrodynamic force was taken into consideration. The conducted calculation can contribute to the pipeline transport further development under the harsh climate conditions of the Russian Federation Arctic shelf territory.

  4. Oil pipeline performance review, 1990

    International Nuclear Information System (INIS)

    1990-01-01

    This paper reviews the environmental performance of Canadian oil pipelines in spill prevention and control in 1990 and compares it with that in 1989. In 1990, in-service length of the systems reporting increased to 34,907 km. Traffic volume was 235 million m 3 . Failures dropped 16% from 1989 to 36. Equipment failures accounted for 47%, corrosion for 22% and operational error for 19% of the failures. Repair, damage and clean-up costs were considerably higher at $5,302,000, of which one external corrosion failure contributed $4,500,000. The average spill size was 130 m 3 with 72 m 3 recovered for a 55.4% recovery rate. No injuries resulted from the failures. An 11 year statistical summary of oil pipeline performance data is included. 3 figs., 5 tabs

    This paper explored issues facing the complex task of managing pipelines that transport large volumes of petroleum products over long distances. Since oil pipelines are generally a few inches wide and several miles long, reasonable amounts of distinct products can be transported with very small loss due to the mixing at liquid boundaries. Optimizing the transportation through oil pipelines in terms of maintenance and environmental safety is a high priority for pipeline operators. This paper presented the Pipesworld model which takes into account features such as product interface constraints, limited product storage capacities and due dates for product delivery. It has been benchmarked as a start-of-art general purpose artificial planning system. This paper also reported the results derived by general purpose artificial intelligence planning systems when applied to the Pipesworld model. It demonstrated how various modelling techniques can be used to enhance the planners performance. Current work in developing Plumber was also presented. This dedicated solver that addresses operational situations uses both general purpose planning techniques as well as domain specific knowledge. When Plumber was incorporated into Pipesworld, its outperformed Fast-Forward, one of the best available general purpose planning systems, suggesting that improved versions of Plumber have the potential to deal with various problem scenarios in pipeline operations. 11 refs., 2 tabs., 3 figs.

    Luhning, R.W.; Anand, A.; Blackmore, T.; Lawson, D.S.

    2002-01-01

    The recoverable reserves of Canada's vast oil deposits is estimated to be 335 billion barrels (bbl), most of which are in the Alberta oil sands. Canada was the largest import supplier of crude oil to the United States in 2001, followed by Saudi Arabia. By 2011, the production of oil sands is expected to increase to 50 per cent of Canada's oil, and conventional oil production will decline as more production will be provided by synthetic light oil and bitumen. This paper lists the announced oil sands projects. If all are to proceed, production would reach 3,445,000 bbl per day by 2011. The three main challenges regarding the transportation and marketing of this new production were described. The first is to expand the physical capacity of existing pipelines. The second is the supply of low viscosity diluent (such as natural gas condensate or synthetic diluent) to reduce the viscosity and density of the bitumen as it passes through the pipelines. The current pipeline specifications and procedures to transport partially upgraded products are presented. The final challenge is the projected refinery market constraint to process the bitumen and synthetic light oil into consumer fuel products. These challenges can be addressed by modifying refineries and increasing Canadian access in Petroleum Administration Defense District (PADD) II and IV. The technology for partial upgrading of bitumen to produce pipeline specification oil, reduce diluent requirements and add sales value, is currently under development. The number of existing refineries to potentially accept partially upgraded product is listed.

    LNG pipelines could help solve some peakshaving problems if operated in conjunction with other facilities that could use the LNG cold recovered during regasification. In some areas at present, LNG is delivered by tanker and regasified near the terminal for transmission through conventional gas pipelines. In other places, utilities liquefy natural gas for easy storage for later peakshaving use. The only chance to avoid the second expensive liquefaction step would be to convey imported LNG through a suitable designed LNG pipeline. The technical problems involved in LNG pipeline construction have basically been solved in recent years, but those pipelines actually constructed have been only short ones. To be economically justified, long-distance LNG lines require additional credit, which could be obtained by selling the LNG cold recovered during regasification to industrial users located in or near the points of gas consumption. Technical details presented cover the pipe material, stress relief, steel composition, pressure enthalpy, bellows-type expansion joints, and mechanical and thermal insulation.

    2017-12-01

    We investigate 85 129 MODIS satellite active fire events from 2007 to 2015 in the Niger Delta of Nigeria. The region is the oil base for Nigerian economy and the hub of oil exploration where oil facilities (i.e. flowlines, flow stations, trunklines, oil wells and oil fields) are domiciled, and from where crude oil and refined products are transported to different Nigerian locations through a network of pipeline systems. Pipeline and other oil facilities are consistently susceptible to oil leaks due to operational or maintenance error, and by acts of deliberate sabotage of the pipeline equipment which often result in explosions and fire outbreaks. We used ground oil spill reports obtained from the National Oil Spill Detection and Response Agency (NOSDRA) database (see www.oilspillmonitor.ng) to validate MODIS satellite data. NOSDRA database shows an estimate of 10 000 spill events from 2007 - 2015. The spill events were filtered to include largest spills by volume and events occurring only in the Niger Delta (i.e. 386 spills). By projecting both MODIS fire and spill as `input vector' layers with `Points' geometry, and the Nigerian pipeline networks as `from vector' layers with `LineString' geometry in a geographical information system, we extracted the nearest MODIS events (i.e. 2192) closed to the pipelines by 1000m distance in spatial vector analysis. The extraction process that defined the nearest distance to the pipelines is based on the global practices of the Right of Way (ROW) in pipeline management that earmarked 30m strip of land to the pipeline. The KML files of the extracted fires in a Google map validated their source origin to be from oil facilities. Land cover mapping confirmed fire anomalies. The aim of the study is to propose a near-real-time monitoring of spill events along pipeline routes using 250 m spatial resolution of MODIS active fire detection sensor when such spills are accompanied by fire events in the study location.

    Full Text Available The author examines the problems and prospects of crude oil and petroleum products transportation market on the European continent. Particular attention is paid to the possibilities of the planned pipeline routes and new supplies of oil and petroleum products. European Union countries have large reserves of hydrocarbons, but it is not enough to fully satisfy domestic consumption. Improved pipeline infrastructure both within the EU and oil pipelines from other countries is an important economic and social factor. Recent developments of this year especially emphasize the importance of strengthening the energy security in the foreign policy of the state. For transporting fuel energy in Europe used the following types of transport: marine (sea and river, truck, railway, and pipeline. It seems necessary to mention the fact that the role of pipeline transport is particularly high in the oil and gas industry. Pipeline transport has an important impact on the formation and developmen t of the fuel and energy complex of the state, as well as regions, as its integral part. An effective system of crude oil and petroleum products pipelines is an important tool for the implementation of public policies, policies at the EU level, allowing the country to regulate the supply of crude oil and petroleum products to the overseas and domestic markets.

    One of the key questions of modern society consists on the rational use of the planet's natural resources and energy. Due to the lack of energy, many companies are forced to reduce their workload, especially during peak hours, because residential demand reaches its top and there is not enough energy to fulfill the needs of all users, which affects major industries. Therefore, using energy more wisely has become a strategic issue for any company, due to the limited supply and also for the excessive cost it represents. With the objective of saving energy and reducing costs for oil pipelines, it has been identified that the increase in energy consumption is primordially related to pumping stations and also by the way many facilities are operated, that is, differently from what was originally designed. Realizing this opportunity, in order to optimize the process, this article intends to examine the possibility of gains evaluating alternatives regarding changes in the pump scheme configuration and non-use of pump stations at peak hours. Initially, an oil pipeline with potential to reduce energy costs was chosen being followed by a history analysis, in order to confirm if there was sufficient room to change the operation mode. After confirming the pipeline choice, the system is briefly described and the literature is reviewed, explaining how the energy cost is calculated and also the main characteristics of a pumping system in series and in parallel. In that sequence, technically feasible alternatives are studied in order to operate and also to negotiate the energy demand contract. Finally, costs are calculated to identify the most economical alternative, that is, for a scenario with no increase in the actual transported volume of the pipeline and for another scenario that considers an increase of about 20%. The conclusion of this study indicates that the chosen pipeline can achieve a reduction on energy costs of up to 25% without the need for investments in new

  13. Oil pipeline energy consumption and efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Hooker, J.N.

    1981-01-01

    This report describes an investigation of energy consumption and efficiency of oil pipelines in the US in 1978. It is based on a simulation of the actual movement of oil on a very detailed representation of the pipeline network, and it uses engineering equations to calculate the energy that pipeline pumps must have exerted on the oil to move it in this manner. The efficiencies of pumps and drivers are estimated so as to arrive at the amount of energy consumed at pumping stations. The throughput in each pipeline segment is estimated by distributing each pipeline company's reported oil movements over its segments in proportions predicted by regression equations that show typical throughput and throughput capacity as functions of pipe diameter. The form of the equations is justified by a generalized cost-engineering study of pipelining, and their parameters are estimated using new techniques developed for the purpose. A simplified model of flow scheduling is chosen on the basis of actual energy use data obtained from a few companies. The study yields energy consumption and intensiveness estimates for crude oil trunk lines, crude oil gathering lines and oil products lines, for the nation as well as by state and by pipe diameter. It characterizes the efficiency of typical pipelines of various diameters operating at capacity. Ancillary results include estimates of oil movements by state and by diameter and approximate pipeline capacity utilization nationwide.

  19. The vulnerability of oil collection pipelines to corrosion under conditions of stratified oil-water emulsion

    1980-01-01

    Problems with oil industry equipment and pipeline corrosion have recently highlighted the problems of increased water content in oil and the presence of biogenic hydrogen sulphide in petroleum matter. These findings underscore the importance of taking these problems into consideration when formulating long-term production plans. A study of pipeline corrosion and its causes, as well as other factors, has permitted researchers to correlate hydrodynamic parameters for gas-fluid transportability and structural contour flows. The water phase simultaneously carries corrosion-active ions of dissolved hydrogen sulphide and material which interact to corrode metal in the lower sections of pipelines. In order to determine the susceptibility of pipelines to corrosion, it is necessary to establish the presence of stratified fluids in oil and water as well as the gas-fluid flow. Analysis has shown that those sections with stratified emulsion could be identified and that it is necessary to disclose the pipeline's ability to withstand such conditions. The proper selection of transport parameters permits the technological protection of the oil collection pipelines. Partially as a result of the increased flow speed guaranteeing an emulsion flow regime for the gas-water-oil flow, it was found that the operational service-life of pipelines could be prolonged by a reduction of corrosion in oil collection pipelines.

    Sekulic, G.; Vrbic, D.

    2004-01-01

    Planning and development of international oil pipeline projects are aimed primarily at enhancing the safety of crude oil supply. Pipeline development is affected by a variety of overlapping factors, such as energy - and environment-protection-related factors, as well as political, economic, legislative, social, technical and technological ones. The success of any pipeline planning, construction and operation in the present conditions will depend upon the degree to which the above factors have been brought in line with global trends. The government should create stable political, economic and legislative frameworks that will meet the global requirements of crude oil transport development. As regards (new) transportation companies, their function is to secure safe transport by providing competitive tariffs and granting environmental protection. A prerequisite for the pipeline planning is to have both major crude oil consumers and producers (as well as their economic and political integrations) consider any state or company as potential partners for crude oil transport and transit, respectively. Croatia and the JANAF transport company have been 'chosen' as one of priority routes for European supply with crude oil from the Caspian region and Russia and one of the directions for Russian crude oil export due to a number of advantages, opportunities and prospects for a successful development. Two international oil pipeline projects - the Druzba Adria Project and the Constanta-Pancevo-Omisalj-Trieste Project - are currently under consideration. The government commitment towards these projects has been documented by the Croatian Energy Development Strategy (April 2002) and by the Programme for its implementation (March 2004). JANAF has assumed the responsibility for carrying out the project preparation activities assigned to it by the Croatian Government and the pertinent ministries. Cooperation between JANAF and government institutions is an integral part of the procedure

    The heavy oil produced offshore needs to be transported through pipelines between different facilities. The pipelines are usually laid down on the seabed and are submitted to low temperatures. Although heavy oils usually present Newtonian behavior, its viscosity is a strong function of temperature. Therefore, the prediction of pressure drops along the pipelines should include the solution of the energy equation and the dependence of viscosity to temperature. In this work, an asymptotic model is developed to study this problem. The flow is considered laminar and the viscosity varies exponentially with temperature. The model includes one-dimensional equations for the temperature and pressure distribution along the pipeline at a prescribed flow rate. The solution of the coupled differential equation is obtained by second-order finite difference. Results show a nonlinear behavior as a result of coupled interaction between the velocity, temperature, and temperature dependent material properties. (author)

    All questions and concerns of pipeline technique are dealt with in detail. Some chapters can be applied for petroleum pipelines only or partly, for example the importance of petroleum pipelines, projecting, calculation, and operation. The sections of pipes and formings, laying, rights of way, and corrosion protection, accessories and remote effect technique, however, are of general interest, for example also for gas pipelines. In the chapter on working material, a very good summary of today's pipe working material including the thermomechanically treated steels is given. Besides methods of improving the toughness, the problems of the corrosion caused by strain cracking and the ways of avoiding it are pointed out. The pipe producing methods and, in the end of the chapter, the tests in the factory are explained. The section of laying deals with the laying methods being applied for years in pipeline construction, a big part referring to welding methods and tests. Active and passive corrosion protection are explained with all details. In addition to the solidity calculation presented with special regard to concerns of petroleum pipelines, theoretical fundaments and calculation methods for pressure are dealt with. Beside general questions of pumps, accessories, and drives, there is a section dealing with measurement and control techniques. Furthermore, remote effect and transmission techniques and news systems are explained in detail. Here, problems are referred to which are applicable not only to the operation of mineral oil pipelines. The book is completed by indications as to pipeline operation emphasizing general operation control, maintenance, repair methods and damage and their elimination. The last chapter contains a collection of the legal fundaments and the technical rules.

    In order to assess risks inherent to an Oil Pipeline, it is imperative to analyze what happens 'outside the process'. HAZID (HAZard IDentification) studies are mainly carried out for this purpose. HAZID is a formal study which identifies hazards and risks associated to an operation or facility and enable its acceptability assessment. It is a brainstorming exercise guided by a typical 'Checklist', divided into four Sections: External, Facilities and Health Hazards and Issues pertaining to Project Execution, which are further subdivided into Hazard Categories. For each Category, there are 'Guide-words' and 'Prompts'. Even if an Oil Pipeline Risk Assessment can be performed by means of the above referred 'Checklist', carrying out the actual process can become lengthy and annoying due to the lack of specificity. This work aims at presenting the most suitable 'Checklist' for the identification of Oil Pipeline Risk Assessment, although it could be used for Gas Pipeline Risk Assessment too. Prepared ad hoc, this list, is based on the spill causes established by CONCAWE (CONservation of Clean Air Water in Europe). Performing Oil Pipeline Risk Assessment by means of specially formulated Checklist enables the Study Team to easily identify risks, shortens execution time and provides both accuracy and specificity.

    The choice of the pumping units' drive of main oil pipelines is of great importance both for design of pipelines and for modernization of existing ones. At the beginning of oil pipeline transport development, due to the limited number and types of energy sources, the choice was not difficult. The combustion energy of the pumped product was often the only available energy resource for its transportation. In this regard, the pipelines that had autonomous energy sources favorably differed from other energy consumers in the sector. With the passage of time, with the development of the country's electricity supply system, the electric drive for power-line equipment of oil pipelines becomes the dominant type of a pumping station drive. Nowadays, the traditional component is an essential factor when choosing some type of the drive. For many years, oil companies have been using electric drives for pumps, while gas transport enterprises prefer self-contained gas turbines.

Critical Infrastructure Protection (CIP should be a key component of the national security especially after the Kenya Defence Forces’ (KDF incursion into Somalia. The merger of Al-Shabaab and Al-Qaeda terrorist groups and the accelerated grenades attack against Kenya in retaliation has become the centre of the debate on terrorism and internal security of the Kenya. The energy resources are strategic assets from the security, political and economic point of view. Kenya as an oil transit country is considered of primary strategic importance at international level. International terrorism has always looked with interest at the oil resource in order to meet its political and economic targets. We argue that Kenya’s oil pipelines are vulnerable to Al-Shabaab and Al-Qaeda terrorist attack. In summary, the article looks at the concept of terrorism within the framework of critical infrastructure protection, the dangers of attacks on oil pipelines, Kenya’s government preparedness and recommendations.

    The optimization of pipeline transportation is a big concern for the transporter companies. This paper is the third of a series of three articles which investigated the application of a system to simulate the human ability to operate a pipeline in an optimized way. The present paper presents the development of a proportional integral (PI) fuzzy controller, in order to optimize pipeline transportation capacity. The fuzzy adaptive PI controller system was developed and tested with a hydraulic simulator. On-field data were used from the OSBRA pipeline. The preliminary tests showed that the performance of the software simulation was satisfactory. It varied the set-point of the conventional controller within the limits of flow meters. The transport capacity of the pipe was maximize without compromising the integrity of the commodities transported. The system developed proved that it can be easily deployed as a specialist optimizing system to be added to SCADA systems.

    Full Text Available In underground mining of solid minerals becoming increasingly common development system with stowing hardening mixtures. In this case the natural ore array after it is replaced by an artificial excavation of solidified filling mixture consisting of binder, aggregates and water. Such a mixture is prepared on the surface on special stowing complexes and transported underground at special stowing pipelines. However, it is transported to the horizons of a few kilometers, which requires a sustainable mode of motion of such a mixture in the pipeline. Hardening stowing mixture changes its rheological characteristics over time, which complicates the calculation of the parameters of pipeline transportation. The article suggests a method of determining the initial parameters of such mixtures: the status coefficient, indicator of transportability, coefficient of hydrodynamic resistance to motion of the mixture. These indicators characterize the mixture in terms of the possibility to transport it through pipes. On the basis of these indicators is proposed methodology for calculating the parameters of pipeline transport hardening filling mixtures in drift mode when traffic on the horizontal part of the mixture under pressure column of the mixture in the vertical part of the backfill of the pipeline. This technique allows stable operation is guaranteed to provide pipeline transportation.

    In connection with modern increased requirements for ecology and safety, the development of diagnostic services complex is obligatory and necessary enabling to ensure the reliable operation of the gas transportation infrastructure. Estimation of oil pipelines technical condition should be carried out not only to establish the current values of the equipment technological parameters in operation, but also to predict the dynamics of changes in the physical and mechanical characteristics of the material, the appearance of defects, etc. to ensure reliable and safe operation. In the paper, existing Russian and foreign methods for evaluation of the oil pipelines reliability are considered, taking into account one of the main factors leading to the appearance of crevice in the pipeline material, i.e. change the shape of its cross-section, - corrosion. Without compromising the generality of the reasoning, the assumption of uniform corrosion wear for the initial rectangular cross section has been made. As a result a formula for calculation the probability of failure-free operation was formulated. The proposed mathematical model makes it possible to predict emergency situations, as well as to determine optimal operating conditions for oil pipelines.

    Crude oil is a complex mixture of hydrocarbons which consists of aromatics, paraffins, naphthenics, resins asphaltenes, etc. When the temperature of crude oil is reduced, the heavy components, like paraffin, will precipitate and deposit on the pipe internal wall in the form of a wax-oil gel. The gel deposit consists of wax crystals that trap some amount of oil. As the temperature gets cooler, more wax will precipitate and the thickness of the wax gel will increase, causing gradual solidification of the crude and eventually the oil stop moving inside the offshore pipeline. Crude oil may not be able to be re-mobilized during re-startup. The effective diameter will be reduced with wax deposition, resulting in several problems, for example, higher pressure drop which means additional pumping energy costs, poor oil quality, use of chemical components like precipitation inhibitors or flowing facilitators, equipment failure, risk of leakage, clogging of the ducts and process equipment. Wax deposition problems can become so sever that the whole pipeline can be completely blocked. It would cost millions of dollars to remediate an offshore pipeline that is blocked by wax. Wax solubility decreases drastically with decreasing temperature. At low temperatures, as encountered in deep water production, is easy to wax precipitate. The highest temperature below which the paraffins begins to precipitate as wax crystals is defined as wax appearance temperature (WAT). Deposition process is a complex free surface problem involving thermodynamics, fluid dynamics, mass and heat transfer. In this work, a numerical analysis of wax deposition by molecular diffusion and shear dispersion mechanisms in crude oil pipeline is studied. Diffusion flux of wax toward the wall is estimated by Fick's law of diffusion, in similar way the shear dispersion; wax concentration gradient at the solid-liquid interface is obtained by the volume fraction conservation equation; and since the wax deposition

    Coal fired power generation will continue to provide energy to the world for the foreseeable future. However, this energy use is a significant contributor to increased atmospheric CO 2 concentration and, hence, global warming. Capture and disposal of CO 2 has received increased R and D attention in the last decade as the technology promises to be the most cost effective for large scale reductions in CO 2 emissions. This paper addresses CO 2 transport via pipeline from capture site to disposal site, in terms of system optimization, energy efficiency and overall economics. Technically, CO 2 can be transported through pipelines in the form of a gas, a supercritical fluid or in the subcooled liquid state. Operationally, most CO 2 pipelines used for enhanced oil recovery transport CO 2 as a supercritical fluid. In this paper, supercritical fluid and subcooled liquid transport are examined and compared, including their impacts on energy efficiency and cost. Using a commercially available process simulator, ASPEN PLUS 10.1, the results show that subcooled liquid transport maximizes the energy efficiency and minimizes the cost of CO 2 transport over long distances under both isothermal and adiabatic conditions. Pipeline transport of subcooled liquid CO 2 can be ideally used in areas of cold climate or by burying and insulating the pipeline. In very warm climates, periodic refrigeration to cool the CO 2 below its critical point of 31.1 o C, may prove economical. Simulations have been used to determine the maximum safe pipeline distances to subsequent booster stations as a function of inlet pressure, environmental temperature and ground level heat flux conditions

    In this paper, the classical PF interval model, proposed for reliability centered maintenance, is used to optimize the preventive replacement policy of a subsea oil pipeline. The pipeline is subject to failure modes that may lead to oil release and pollution of the sea. The proposed replacement policy is based on regular condition measurements of the quality of an internal pipeline coating (lining). Holes in the coating will expose the pipe material (steel) to a corrosive environment. It is, therefore, important to identify holes in the coating and take action before the corrosion penetrates the pipe wall. The model proposed in the paper can be used to determine the inspection interval that minimizes the average maintenance cost per time unit. The model formulation is outlined and illustrative examples are solved. The mathematical evaluation of the replacement policy requires numerous assumptions. These assumptions have to be tailored to the specific application. The assumptions and the data provided are included for illustrative purposes to exemplify potential results that may be obtained by using the replacement policy

    One the most important priority identified with the framework of the long-term Republican development aim implementation defined in the Programme of Long-Term Development of Republic of Kazakhstan by 2030 is exploration of huge hydrocarbon reserves. Strategic direction of Kazakhstan petroleum industry development is a comprehensive approach towards the improvement all elements of the complex processing chain, from exploration to production and from transportation to oil and processed product marketing. Republican Association of Young Engineers and Specialists, Engineering Academy of the Republic of Kazakhstan (RAMIS EA RK) considers the most perspective and realistic route. The pipeline will pass from Western region of Kazakhstan to Kumkol further via the existing Omsk-Chardzhou pipeline, Turkmenistan, Western Afghanistan, Pakistan to sea terminal; on the Pakistan coast of the Arabian Sea. Omsk-Chardzhou pipeline was built 12 years ago and is currently no operating. Its length is 2.000 km with 1.800 km crossing Kazakhstan's territory. Even now this pipeline is enable of transporting up to 20 million tonnes of oil per year with the optional increase up to 30 million. Construction of similar pipeline could have cost $2 billion. Connecting Atyrau-Kumkol and Omsk-Chardzhou pipelines could enable Russia and Kazakhstan to penetrate, via Central Asia, Indian and South Asian countries to the Arabian Sea. According to the World Bank Data this region will be rapidly developing within next 15-20 years. During 1995-2010 the estimated demand for the hydrocarbon should double, from 18.0 to 31.69 million tonnes per annual. This means an annual average growth rate of 3.8 %, the highest demand growth rate in the world on petroleum. Transportation of one barrel of West-Siberian oil via Omsk-Pavlodar-Shymkent-Chardzhou route towards the Indian Ocean will bring additional two dollars revenue as compared with the existing route transportation. For the pre-Caspian oil revenue will reach

    Carbon dioxide pipelines are anticipated to be a key element in CCS (Carbon Capture and Sequestration) to transport the carbon dioxide to sequestration sites or to oil fields for use in enhanced oil recovery applications. However the economics of CCS are such that the operations are economically challenged. The concept of using super critical (liquid) carbon dioxide in a slurry pipeline is to use the pipeline constructed for environmental purposes to transport marketable products such as sulphur, petroleum coke, limestone and others to market thereby generating additional income to make CCS carbon dioxide transportation economically attractive.

    This work presents an optimization structure to support the operational decision making of scheduling activities in a multi product pipeline with multiple deliveries. This pipeline connects, in sequence, 6 operational areas: one is the main refinery, and the 5 remaining are distribution centers, each one with specific capacity of storage. Basically, the refinery pumps derivatives, such as diesel and gasoline, in a unidirectional flow to distribution centers, in a way to supply their demands. The solution kernel is underlined in a hybrid structure, using heuristics and Mixed Integer Linear Programming (MILP) modeling, executed iteratively. Details of storage curves and flow rate of pipelines are obtained in the proposed approach, expanding the results of Kira et al. (2010). Additionally, the proposed approach is able to deal with discrete demands along the scheduling horizon. Thus, this hybrid structure makes possible to obtain operational scheduling solutions at a low CPU times (few minutes), using real data scenarios, whose horizon length has at least 30 days. (author)

    This document provides a summary of the pipeline performance and reportable pipeline failures of liquid hydrocarbon pipelines in Canada, for the years 1995 through 1998. The year 1994 was the last one for which the Oil Pipeline Performance Review (OPPR) was published on an annual basis. The OPPR will continue to be published until such time as the Pipeline Risk Assesment Sub-Committee (PRASC) has obtained enough pipeline failure data to be aggregated into a meaningful report. The shifts in the mix of reporting pipeline companies is apparent in the data presented, comparing the volumes transported and the traffic volume during the previous ten-year period. Another table presents a summary of the failures which occurred during the period under consideration, 1995-1998, allowing for a comparison with the data for the previous ten-year period. From the current perspective and from an historical context, this document provides a statistical review of the performance of the pipelines, covering refined petroleum product pipelines, clean oil pipelines and High Vapour Pressure (HVP) pipelines downstream of battery limits. Classified as reportable are spills of 1.5 cubic metre or more of liquid hydrocarbons, any amount of HVP material, any incident involving an injury, a death, a fire, or an explosion. For those companies that responded to the survey, the major items, including number of failures and volumes released are accurate. Samples of the forms used for collecting the information are provided within the document. 6 tabs., 1 fig

    Oil pipelines network is one of the most important facilities of energy transportation. But oil pipelines network accident may result in serious disasters. Some analysis models for these accidents have been established mainly based on three methods, including event-tree, accident simulation and Bayesian network. Among these methods, Bayesian network is suitable for probabilistic analysis. But not all the important influencing factors are considered and the deployment rule of the factors has not been established. This paper proposed a probabilistic analysis model of oil pipelines network based on Bayesian network. Most of the important influencing factors, including the key environment condition and emergency response are considered in this model. Moreover, the paper also introduces a deployment rule for these factors. The model can be used in probabilistic analysis and sensitive analysis of oil pipelines network accident.

    Full Text Available The commercial transportation of crude oil and petroleum products by pipeline is receiving increased attention in South Africa. Transnet Pipeline Transport has recently obtained permission from the National Energy Regulator of South Africa (Nersa to construct and operate a new petroleum products pipeline of 60 cm diameter from Durban to Gauteng. At an operating speed of 10 km/h the proposed 60 cm Transnet pipeline would be able to deliver 3,54 million litres of petroleum product per hour. This is equivalent to 89 deliveries per hour using road tank vehicles with an average carrying capacity of 40 000 litres of fuel per vehicle. This pipeline throughput is also equivalent to two trains departing per hour, each consisting of 42 petroleum tank wagons with an average carrying capacity of 42 500 litres of fuel per wagon. Considering that such road trucks and rail wagons return empty to the upstream refineries in Durban, it is clear that there is no tenable long-term alternative to pipeline transport:pipeline transport is substantially cheaper than road and rail transport;pipeline transport is much safer than rail and especially road transport; andpipeline transport frees up alternative road and rail transport capacity.Pipeline transport is a non-containerised bulk mode of transport for the carriage of suitable liquids (for example, petroleum commodities, which include crude oil, refined fuel products and liquid petro-chemicals, gas, slurrified coal and certain water-suspended ores and minerals. InSouth Africa, petroleum products account for the majority of commercial pipeline traffic, followed by crude oil and natural gas. There are three basic types of petroleum pipeline transport systems:Gathering pipeline systemsCrude oil trunk pipeline systemsRefined products pipeline systems Collectively, these systems provide a continuous link between extraction, processing, distribution, and wholesalers’ depots in areas of consumption.

    Full Text Available Crude oil plays an important role in providing the energy supply of the world, and pipelines have long been recognized as the safest and most efficient means of transporting oil and its products. However, the transportation process also faces the challenges of asphaltene-paraffin structural interactions, pipeline pressure losses and energy consumption. In order to determine the role of drag-reducing surfactant additives in the transportation of crude oils, experiments of wax deposition inhibition and drag reduction of different oil in pipelines with a biobased surfactant obtained by enzymatic syntheses were carried out. The results indicated that heavy oil transportation in the pipeline is remarkably enhanced by creating stable oil-in-water (O/W emulsion with the surfactant additive. The wax appearance temperature (WAT and pour point were modified, and the formation of a space-filling network of interlocking wax crystals was prevented at low temperature by adding a small concentration of the surfactant additive. A maximum viscosity reduction of 70% and a drag reduction of 40% for light crude oil flows in pipelines were obtained with the surfactant additive at a concentration of 100 mg/L. Furthermore, a successful field application of the drag-reducing surfactant in a light crude oil pipeline in Daqing Oilfield was demonstrated. Hence, the use of biobased surfactant obtained by enzymatic syntheses in oil transportation is a potential method to address the current challenges, which could result in a significant energy savings and a considerable reduction of the operating cost.

    Pipeline transmission systems have been designed traditionally using steady state simulations. Steady state simulation provided sufficient values for simple systems, but is limited in dealing with surges in flow rates, loss of facilities and facility operation. A dynamic approach is required to test the capacity of a system for various fluids. This paper investigated the use of transient analysis of liquid pipelines in order to improve the design of these pipelines and to achieve operational benefits. The transient method and its use are discussed. Dynamic analysis was applied to the Keystone Pipeline Project. The purpose of the study was first to determine the system capacity and data for transportation of Heavy DilBit, and then to implement batch transportation of a volume of synthetic crude oil. It was found that the use of transient modeling in design and operational assessment of a liquid pipeline ensures system capability, control, safety and integrity.

    The rationale developed by a United Nations team to estimate the fate and transport of spilled oil remaining on the ground in the Pechora River basin in Russia following the Komi Pipeline spill disaster, was presented. The team consisted of experts from Norway, Canada, the United States and the European Union. Detailed background of the spill event, petroleum industry setting, geographic setting and hydrology of the regions was presented. Nine contaminated sites were identified. A worst case scenario was developed for the fate of the spilled oil. It was estimated that 93 000 - 97 000 tonnes of oil remained on the ground. Further pollution of the environment outside of Russia was considered unlikely under the circumstances, but petroleum contamination of the drinking water, tar balls and residual oil were expected to continue to persist in the affected area for many months. The UN team concluded that chronic pollution posed a significant threat to the region's natural resources. 4 refs., 3 figs

    Jittamai, Phongchai

    This dissertation defines the operational problems of, and develops solution methodologies for, a distribution of multiple products into oil pipeline subject to delivery time-windows constraints. A multiple-product oil pipeline is a pipeline system composing of pipes, pumps, valves and storage facilities used to transport different types of liquids. Typically, products delivered by pipelines are petroleum of different grades moving either from production facilities to refineries or from refineries to distributors. Time-windows, which are generally used in logistics and scheduling areas, are incorporated in this study. The distribution of multiple products into oil pipeline subject to delivery time-windows is modeled as multicommodity network flow structure and mathematically formulated. The main focus of this dissertation is the investigation of operating issues and problem complexity of single-source pipeline problems and also providing solution methodology to compute input schedule that yields minimum total time violation from due delivery time-windows. The problem is proved to be NP-complete. The heuristic approach, a reversed-flow algorithm, is developed based on pipeline flow reversibility to compute input schedule for the pipeline problem. This algorithm is implemented in no longer than O(T·E) time. This dissertation also extends the study to examine some operating attributes and problem complexity of multiple-source pipelines. The multiple-source pipeline problem is also NP-complete. A heuristic algorithm modified from the one used in single-source pipeline problems is introduced. This algorithm can also be implemented in no longer than O(T·E) time. Computational results are presented for both methodologies on randomly generated problem sets. The computational experience indicates that reversed-flow algorithms provide good solutions in comparison with the optimal solutions. Only 25% of the problems tested were more than 30% greater than optimal values and

    Highlights: ► We build a static hydrodynamic model of CO 2 pipeline for CCS application. ► We study the impact on pressure drop of pipeline by viscosity, density and elevation. ► We point out that density has a bigger impact on pressure drop than viscosity. ► We suggest dense phase transport is preferred than supercritical state. ► We present cost-optimal pipeline diameters for different flowrates and distances. - Abstract: Carbon capture and sequestration (CCS) is an important option for CO 2 mitigation and an optimized CO 2 pipeline transport system is necessary for large scale CCS implementation. In the present work, a hydrodynamic model for CO 2 pipeline transport was built up and the hydrodynamic performances of CO 2 pipeline as well as the impacts of multiple factors on pressure drop behavior along the pipeline were studied. Based on the model, an economic model was established to optimize the CO 2 pipeline transport system economically and to evaluate the unit transport cost of CO 2 pipeline in China. The hydrodynamic model results show that pipe diameter, soil temperature, and pipeline elevation change have significant influence on the pressure drop behavior of CO 2 in the pipeline. The design of pipeline system, including pipeline diameter and number of boosters etc., was optimized to achieve a lowest unit CO 2 transport cost. In regarding to the unit cost, when the transport flow rate and distance are between 1–5 MtCO 2 /year and 100–500 km, respectively, the unit CO 2 transport cost mainly lies between 0.1–0.6 RMB/(tCO 2 km) and electricity consumption cost of the pipeline inlet compressor was found to take more than 60% of the total cost. The present work provides reference for CO 2 transport pipeline design and for feasibility evaluation of potential CCS projects in China.

    Underground pipelines are built all over the world and the knowledge of their thermal interaction with the soil is crucial for their design. This paper studies the "thermal influenced zone" produced by a buried pipeline and the parameters that can influence its extension by 2D-steady state CFD simulations with the aim to improve the design of new pipelines in permafrost. In order to represent a real case, the study is referred to the Eastern Siberia-Pacific Ocean Oil Pipeline at the three stations of Mo'he, Jiagedaqi and Qiqi'har. Different burial depth sand diameters of the pipe are analyzed; the simulation results show that the effect of the oil pipeline diameter on the thermal field increases with the increase of the distance from the starting station.

    Nigeria, the largest producer of crude oil in Africa occupies sixth position in the world. Despite such huge oil revenue potentials, its pipeline network system is consistently susceptible to leaks causing oil spills. We investigate ground based spill events which are caused by operational error, equipment failure and most importantly by deliberate attacks along the major pipeline transport system. Sometimes, these spills are accompanied with fire explosion caused by accidental discharge, natural or illegal refineries in the creeds, etc. MODIS satellites fires data corresponding to the times and spill events (i.e. ground based data) of the Area of Interest (AOI) show significant correlation. The open source Quantum Geographical Information System (QGIS) was used to validate the dataset and the spatiotemporal analyses of the oil spill fires were expressed. We demonstrate that through QGIS and Google Earth (using the time sliders), we can identify and monitor oil spills when they are attended with fire events along the pipeline transport system accordingly. This is shown through the spatiotemporal images of the fires. Evidence of such fire cases resulting from bunt vegetation as different from industrial and domestic fire is also presented. Detecting oil spill fires in the study location may not require an enormous terabyte of image processing: we can however rely on a near-real-time (NRT) MODIS data that is readily available twice daily to detect oil spill fire as early warning signal for those hotspots areas where cases of oil seepage is significant in Nigeria.

    Oil production from Alaskan North Slope oil fields has steadily declined. In the near future, ANS crude oil production will decline to such a level (200,000 to 400,000 bbl/day) that maintaining economic operation of the Trans-Alaska Pipeline System (TAPS) will require pumping alternative products through the system. Heavy oil deposits in the West Sak and Ugnu formations are a potential resource, although transporting these products involves addressing important sedimentation issues. One possibility is the use of Gas-to-Liquid (GTL) technology. Estimated recoverable gas reserves of 38 trillion cubic feet (TCF) on the North Slope of Alaska can be converted to liquid with GTL technology and combined with the heavy oils for a product suitable for pipeline transport. Issues that could affect transport of this such products through TAPS include pumpability of GTL and crude oil blends, cold restart of the pipeline following a prolonged winter shutdown, and solids deposition inside the pipeline. This study examined several key fluid properties of GTL, crude oil and four selected blends under TAPS operating conditions. Key measurements included Reid Vapor Pressure, density and viscosity, PVT properties, and solids deposition. Results showed that gel strength is not a significant factor for the ratios of GTL-crude oil blend mixtures (1:1; 1:2; 1:3; 1:4) tested under TAPS cold re-start conditions at temperatures above - 20 F, although Bingham fluid flow characteristics exhibited by the blends at low temperatures indicate high pumping power requirements following prolonged shutdown. Solids deposition is a major concern for all studied blends. For the commingled flow profile studied, decreased throughput can result in increased and more rapid solid deposition along the pipe wall, resulting in more frequent pigging of the pipeline or, if left unchecked, pipeline corrosion.

    Oil spills due to oil pipelines is a very frequent problem in Mexico. Petroleos Mexicanos (PEMEX), very concerned with the environmental agenda, has been developing inspection and correction plans for zones around oil pipelines pumping stations and pipeline right-of-way. These stations are located at regular intervals of kilometres along the pipelines. In this study, two sections of an oil pipeline and two pipeline pumping stations zones are characterized in terms of the presence of Total Petroleum Hydrocarbons (TPHs) and Polycyclic Aromatic Hydrocarbons (PAHs). The study comprehends sampling of the areas, delimitation of contamination in the vertical and horizontal extension, analysis of the sampled soils regarding TPHs content and, in some cases, the 16 PAHs considered as priority by USEPA, calculation of areas and volumes contaminated (according to Mexican legislation, specifically NOM-EM-138-ECOL-2002) and, finally, a proposal for the best remediation techniques suitable for the contamination levels and the localization of contaminants.

  8. THE DEVELOPMENT AND THE STRATEGY OF THE OIL AND GAS PIPELINES OF RUSSIA

    Science.gov (United States)

    Motomura, Masumi

    The Russian oil and gas industry earns more than half of the Russian tax revenue and foreign currency, and has been playing the role of the backbone of the state economy through the eras of the Soviet Union and the Russian Federation. With the elongation of distance to the European market from the oil producing regions, starting from Baku in the era of Imperial Russia to the Second Baku (Volga-Ural) and the third Baku (West Siberia) in turn, the role of the oil pipeline system as the transportation infrastructure became more and more important and the deployment of pipelines has become one of the indispensable pillars of oil strategy. Now, the oil pipeline network is to reach the Pacific Ocean, which will enable Northeast Asia to be added as a destination for Russian oil, with a result of expanding influence for Russia in these regions. On the other hand, gas exports from the Soviet Union to Eastern Europe started in 1967 by constructing a trunk pipeline from Ukraine, which was extended to West Germany in 1973, overcoming the confrontation between the East and the West and becoming a regional stabilizer. The United States considered this pipeline as an energy weapon and criticized this deal by saying that when Soviet gas flows to Western Europe, its political influence must flow like the gas itself. However, the Soviet Union collapsed in 1991, while gas transportation continued without any disruption. This is evidence that the gas pipeline from the Soviet Union was purely for a business purpose and was not politicized. Recently, Russia is aiming to export gas to northeastern Asia, which is expected to be a new stabilizer in this region, although different types of diffi culties (especially about the method of determination of the gas price) still need to be resolved.

  10. Outlook '98 - Gas and oil pipelines

    International Nuclear Information System (INIS)

    Curtis, B.

    1998-01-01

    Due to rising North American demand, especially by the United States, by the end of 1997 there were plans to build 15 new pipelines over the next three years, at an estimated cost of $17 billion. Canada''s proximity to the United States, combined with huge Canadian reserves, and the fact that Canada already supplies some 15 per cent of U.S. requirements, makes Canada the obvious choice for filling future demand. This explains why most, if not all, current pipeline expansion projects are targeting markets in the U.S. Market forces will determine which of the projects will actually go forward. From the point of view of the Canadian Energy Pipeline Association pipeline regulatory reform, pipeline safety, integrity and climate change will be the Association''s key concerns during 1998. To that end, the Association is cooperating with the National Energy Board in a multi-million dollar study of stress corrosion cracking. The Association has also developed a Manual of Recommended Practices for the use of member companies to assist them to tailor stress corrosion cracking practices to their own operations. Meeting Canada''s commitment at the Kyoto Conference for greenhouse gas emissions of six per cent below 1990 levels by the year 2008 to 2012 (in effect a 25 per cent reduction from the level anticipated in the year 2000), a very difficult task according to industry experts, is also among the high priority items on the pipeline industry''s agenda for 1998

    One of the reasons for shutdowns of main oil pipelines is stoppage of the cleaning unit in cleaning of the inner surface of paraffin deposits caused by damage to the cleaning unit. The authors propose a method of searching for and determining the condition of the cleaning unit not requiring dismantling of the pipeline according to which the initial search for the cleaning unit is done with acoustic instruments (the increased acoustic noise at the point of stoppage of its is recorded) and subsequent inspection by a radiographic method. An experimental model of an instrument was developed making it possible to determine the location of a cleaning unit in an oil pipeline in stoppage of it from the acoustic noise. The instrument consists of two blocks, the remote sensor and the indicator block, which are connected to each other with a cable up to 10 m long. The design makes it possible to place the sensor at any accessible point of a linear part of the pipeline (in a pit, on a valve, etc.) while the indicator block may remain on the surface of the ground. The results obtained make it possible to adopt the optimum solutions on elimination of their malfunctioning and to prevent emergency situations without dismantling of the pipeline. With the equipment developed it is possible to inspect oil and gas pipelines with different reasons for a reduction in their throughput

    This paper addresses the development and the architecture of a corporative package to aid the operational decision-making of the scheduling activities in a real-world pipeline network for oil derivatives. The system was developed based on a service-oriented architecture, allowing the development of Web applications to define the network scheduling, as well as graphic display of the movements. The solution of the scheduling is generated by an optimization block as a service of this application. However, this paper emphasizes the description of the architecture and its functionalities, which was defined with the help of experienced programmers. (author)

  13. MIC in long oil pipelines: diagnosis, treatment and monitoring

    2011-07-01

    The paper presents the diagnosis, treatment and monitoring of microbial influenced corrosion (MIC) in long oil pipelines. The presence of inorganic solids, bacteria, gases and organic acids in produced water in the oil pipelines causes MIC, which is hard to detect or test and it does not produce any unique type of corrosion. Chemical analysis of water from pig runs is presented in a tabular form and a graphical analysis of pig sludge solids is shown. From the biometabolite analysis, 23 putative hydrocarbon biometabolites were identified and biometabolites for the anaerobic biodegradation of aromatic HC were also detected. Operational considerations include the history of MIC in upstream pipelines, water slugging, and presence of suspended solids, among others. From microbiological, chemical, metallurgical and operational evidence it was suggested that MIC is a likely mechanism. The mitigation program is described and suggestions for successful mitigation measures include removal of oxygen sources, scale inhibitor injection, and increasing CO2 inhibitor concentration.

    In the last decades, the offshore industry has expanded thanks to the development of equipment for subsea operation. In such installations, protection equipment can be adapted to the installation's design in order to avoid surge pressure effects and ensure safety and integrity of the system, predicting transient effect is therefore very important. The purpose of this study is to predict the surge pressure on refrigerated LPG and gasoline pipelines during unpredicted closure of valves. Flowmaster software was used to carry out the simulations and its results were then validated with a methodology that applied the characteristics method based on Wylie and Streeter assumptions. Results showed that surge pressures during transient effect for both refrigerated LPG and Gasoline pipeline systems were less than the maximum allowable operating pressure and therefore no control dispositive installations are geeded. This study showed that the use of these computer models can ensure the optimization of the system and provide cost effective solutions.

    2008-07-01

    Gels composed of wax crystals may sometimes form when crude oils are transported in pipelines when ambient temperatures are low. The gels may stop the pipe flow, making it difficult or even impossible to restart the flow without breaking the pipe. Rheology and FTIR techniques were used to study the problem and to characterize transparent model waxy crude oils in pipeline flow experiments. These model oils were formulated without any highly volatile components to enhance the reproducibility of the rheology tests. Results were presented for the time- and temperature-dependent rheology of the model waxy crude oils as obtained in linear oscillatory shear and in creep-recovery experiments. The model oils were shown to exhibit many of the rheological features reported for real crude oils, such as 3 distinct apparent yield stresses, notably static yield stress, dynamic yield stress, and elastic-limit yield stress. It was concluded that of the 3, the static yield stress value, particularly its time dependence, can best be used to predict the restart behaviour observed for the same gel in model pipelines.

  20. Predicting wear of hydrotransport pipelines in oil sand slurries

    An overview of erosion and corrosion methods and techniques was presented. Wear to pipelines is influenced by slurry flow and chemistry; solids loading; and electrochemical interactions. While several experimental techniques have been developed to rank the performance of different pipeline materials, experiments do not currently provide accurate quantitative prediction of pipeline wear in the field. Rotating cylinder electrodes (RCE) and jet impingement methods are used to study the effect of flow velocity on corrosion rate. Slurry pot erosion-corrosion testers are used to rank materials for use in more dilute, less turbulent slurries. Coriolois slurry erosion testers are used to rank the erosion resistance of different pipeline materials. A pilot-scale flow loop is now being constructed by the Alberta Research Council (ARC) in order to replicate wet erosion phenomena in oil sands applications. The flow loop will be used to simulate the field conditions of oil sands pipelines and develop predictive wear data and models. Coulombic shear stress and characteristic wall velocities have been determined using a 2-layer model designed to represent flow as 2 distinct layers. To date, the flow loop pilot study has demonstrated that wear rates in smaller diameter flow loops are not significantly different than larger diameter field installations. Preliminary calculations have demonstrated that the flow loop can be used to accurately simulate the hydrodynamics and wear typically experienced in field slurry flows. 67 refs., 2 tabs., 7 figs.

    In the past 20 years of its operation, JANAF has contributed not only to the domestic refineries' costs decrease and the improvement of their efficiency but also to the internationalisation of the Croatian energy system and its globalisation. The implementation of new JANAF development projects in co-operation with international companies would intensity the JANAF connection to the European oil pipeline network and improve the oil supply safety of domestic refineries. New projects would at the same time enable oil export from Russia and other FSU states to the international oil market, such as oil transport from the INA oil fields in Russia. The JANAF development projects would help evaluate the existing capacities and infrastructure in terms of quality. They would be realised according to the principles of Energy Charter Treaty, the new Croatian energy system legislation and Energy Strategy. (author)

    1977-09-09

    This report identifies potential energy-conservative pipeline innovations that are most energy- and cost-effective and formulates recommendations for the R, D, and D programs needed to exploit those opportunities. From a candidate field of over twenty classes of efficiency improvements, eight systems are recommended for pursuit. Most of these possess two highly important attributes: large potential energy savings and broad applicability outside the pipeline industry. The R, D, and D program for each improvement and the recommended immediate next step are described. The eight technologies recommended for R, D, and D are gas-fired combined cycle compressor station; internally cooled internal combustion engine; methanol-coal slurry pipeline; methanol-coal slurry-fired and coal-fired engines; indirect-fired coal-burning combined-cycle pump station; fuel-cell pump station; drag-reducing additives in liquid pipelines; and internal coatings in pipelines.

    2006-08-01

    We have developed, in conjunction with Solartron ISA, an electromagnetic cavity resonator based sensor for multiphase flow measurement through an oil pipeline. This sensor is non-intrusive and transmits low power (10 mW) radio frequencies (RF) in the range of 100-350 MHz and detects the pipeline contents using resonant peaks captured instantaneously. The multiple resonances from each captured RF spectrum are analysed to determine the phase fractions in the pipeline. An industrial version of the sensor for a 102 mm (4 inch) diameter pipe has been constructed and results from this sensor are compared to those given by simulations performed using the electromagnetic high frequency structure simulator software package HFSS. This paper was presented at the 13th International Conference on Sensors and held in Chatham, Kent, on 6-7 September 2005.

    Pelmulder, S.D.; Eguchi, R.T.

    1991-01-01

    This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks due to earthquakes. Risk is measured both as volume of oil released and remediation cost. The methodology was developed for use on a regional scale and thus relies on a limited amount of input data. Monte Carlo techniques are used to simulate earthquake events, while a deterministic model is used to estimate the volume of oil released at a particular site. A library of cost models is used to estimate the contamination and resulting remediation cost based on the volume of oil released and the general site conditions. This methodology has been implemented in a computer program, OILOSS, and the results are presented as annual frequency of exceedence curves for volume of oil released and cost of remediation

    2015-08-01

    Full Text Available Taking into consideration both shipping and pipeline transport, this paper first analysed the risk factors for different modes of crude oil import transportation. Then, based on the minimum of both transportation cost and overall risk, a multi-objective programming model was established to optimize the transportation network of crude oil import, and the genetic algorithm and ant colony algorithm were employed to solve the problem. The optimized result shows that VLCC (Very Large Crude Carrier is superior in long distance sea transportation, whereas pipeline transport is more secure than sea transport. Finally, this paper provides related safeguard suggestions on crude oil import transportation.

    This paper presents the implementation by PETROBRAS Transporte S.A. - TRANSPETRO of its Oil Pipelines and Terminals Standardization Program (PRONOT) within the scope of the 'Integrated Management System' (IMS). This program, launched in 2006 in the regions where the company operates, aims at standardizing all of its oil pipeline and terminal operations. Its implementation was planned in two phases: the first, already successfully concluded, refers to pipeline operations, industrial maintenance and right-of-way activities management; and the second, initiated in 2009, encompasses cross-sectional activities including health, safety and environment (HSE); training and development of oil pipeline workforce; communication with stake holders; oil pipeline integrity; and engineering project requirements. The documental structures of TRANSPETRO IMS and PRONOT are described and represented graphically to emphasize the intentional alignment of the standardization process carried out by the Oil Pipelines and Terminals Unit to the corporate IMS, based upon national and international literature review and through practical research focusing on the best international practices.

    2015-01-01

    Full Text Available The article deals with fuel and energy complex of Canada as one of the largest manufacturers of primary energy in the world, which provides up to 6 percent of the world energy supply. Only the Russian Federation, PRC, the United States of America and the Kingdom of Saudi Arabia have larger production volumes. However, oil plays the most significant role in Canada's energy exports. It is estimated that its proven reserves are sufficient to meet the demand for 140 years at current production rate. The relevance of the study, including the analysis of fuel and energy complex of Canada, is due to the fact that such comparison and synthesis of data on the amount of recoverable oil reserves, the volume of its production, imports, exports and transit of oil and oil products, the distribution of oil for transportation (via pipelines, rail, sea, road, strategic oil field, refining and transportation of oil and oil products development projects, as well as implementation of Canada's best practices in the Russian Federation, is being developed for the first time. In addition, the data given in previously published articles on the subject, due to the dynamic development of the industry, are obsolete and do not reflect the real situation.

    The study and modeling of corrosion processes aim at the accomplishment of three primary objectives: to increase safety operation margins, to reduce maintenance costs and to optimize available resources. The Integrity Expert System is based on a statistical propagation model of defects reported by high resolution magnetic inspection tool (MFL), fed with the information provided by corrosion sensors, repair interventions, field surveys and future inspections. As model results, defect depth, remaining strength and failure probability distributions were obtained. From the analysis, feasible courses of action were established: a medium term repair plan, an internal inspection program and both monitoring and mitigation technologies. System implementation in OLDELVAL was translated into two major effects of importance for the company integrity program: reduction in the pipeline probability of failure by corrosion by means of programmed repairs and optimization of the internal inspection investment plan by mans of an alternative programming.

    We present a novel approach for the detection of leakage in oil pipelines using methods of fiber optic distributed sensors, a presence-of-oil based actuator, and Optical Time Domain Reflectometry (OTDR). While the basic concepts of our approach are well understood, the integration of the components into a complete system is a real world engineering design problem. Our focus has been on the development of the actuator design and testing using installed dark fiber. Initial results are promising, however environmental studies into the long term effects of exposure to the environment are still pending.

    2010-07-01

    In the United States, the Pipeline and Hazardous Materials Safety Administration (PHMSA) funded a joint academy-industry research project, which developed and refined a free-swimming tool called SmartBall. The tool swims through the pipeline and gives results at a much lower cost than current leak detection methods, and it can detect leaks as small as 0.03 gpm of oil. GPS-synchronized above-ground loggers capture acoustic signals and record the passage of the tool through the pipeline. The tool is spherical and smaller than the pipe, through which it rolls silently; it can overcome obstacles that could otherwise make a pipeline unpiggable. SmartBall uses the great potential of acoustic detection, because when a pressurized product leaks from a pipe, it produces a distinctive acoustic signal that travels through the product; at the same time, it overcomes the problem caused by the very limited range of this signal. This technology can prevent enormous economic consequences such as a 50,000-gallon gasoline spill that happened in 2003 between Tucson and Phoenix.

    This paper describes the experience of PETROBRAS Transporte S.A. - TRANSPETRO concerning standardization of its industrial maintenance of oil pipelines and terminals. This standardization initiative has been carried out within the Oil Pipelines and Terminals Standardization Program (PRONOT), focusing on planning, preparation and implementation of standards and five corporate operational procedures referring to TRANSPETRO's industrial maintenance activities. The process promoted the integration of isolated regional initiatives, and consequently the sense of unity and creation of a nucleus consisting of 30 professionals who mobilized a learning network with great capillarity. In this context, the paper presents the results of implementing corporate standards, based on internationally recognized yardsticks such as American Petroleum Institute (API), US Department of Transportation (DOT) and American Society of Mechanical Engineers (ASME), as well as PETROBRAS standards. It covers the following topics: an overview of the whole process; preparation of corporate operational procedures, which resulted in a total of 5 standards against 60 in the original situation; preparation and implementation of visual quick guides corresponding to the new corporate operational procedures; and proposal of a set of industrial maintenance performance indicators in compliance with operational guidelines established by TRANSPETRO's Oil Pipelines and Terminals business segment.

    2000-01-01

    The logistics of transporting partially upgraded crudes in feeder and trunk pipeline systems is discussed. Logistic alternatives are evaluated against economic drivers for partial upgrading, and the impact of crude transportation logistics on the quality of crude that reaches refinery gates is assessed. The potential advantages of partial upgrading in the field are reviewed (including reduction of diluent required to meet pipeline density and viscosity specifications, cost and availability of diluent, limitations in diluent transportation infrastructure, increased chemical stability, increased attractiveness to refineries, shortage of refinery coking capacity, higher market value). The pros and cons of various upgrading processes, and the implications of each for producers and refiners are explained. The advantages of moving to large common streams, as opposed to the concept of 'boutique' crudes, are stressed as the surest way for producers to realize the maximum value of partially upgraded crudes

    Full Text Available Computational tools for simulation of multiphase flow in oil pipelines are of great importance for the determination of the technical feasibility of the production in oilfields. The present article presents the mathematical and numerical modeling of the oil biphasic flow in a partially submerged onshore pipeline. The biphasic behavior of the heavy oil of 13,2ºAPI is translated by the Dukler correlation. The oil’s viscosity is regarded as dependent on the temperature and on the API density of the oil by means of the Hossain correlation. The pipeline, of 3,600m and 4 inches (10.16cm in diameter, transports the oil from a collecting station to a storage center and consists of three sections. The first and third sections are above ground and are in contact with the external environment. The intermediate section is sitting on the river bed and is the critical part of the pipeline, once high heat losses are observed. The influence on the type of pipe insulation in the pressure and temperature gradients was analyzed with the aid of commercial 1D software Pipesim®. The results, of this 1D and non-isothermal problem with prescribed outlet pressure, show that the use of isolation when appropriately designed in terms of material quality and thickness is of utmost importance to maintain the heat transfer at low levels, in order to ensure the movement of fluids in long sections without compromising the system operation.

    1993-01-01

    In December 1991, a pipeline ruptured near Fountain Inn, South Carolina, resulting in the release of approximately 13,000 barrels of No. 2 fuel oil to the inland surface water system. Final estimates provided by CPC for the amount of oil discharged from the pipeline rupture indicate that up to 13,100 barrels (over 555,000 gallons) of No. 2 fuel oil were released into the environment - of which approximately 12,600 barrels (530,000 gallons) were recovered. The recovery rate of greater than 95% of spilled product is considered to be well above average for a major discharge of oil in the inland zone. The primary factors influencing this rate of recovery were the ability to provide containment at the leak site within 12 hours of the release and to establish containment downstream of the spill in advance of the leading edge of the oil plume. A total of 23,320 barrels (almost a million gallons) of an oil/water mixture were collected within a five day period. Although the water systems in Clinton and Whitmire were affected by the spill, adequate backup systems provided alternate drinking water to these residents until the primary intakes could be opened. However, this spill caused significant environmental impacts. The South Carolina Wildlife and Marine Resources Department reports that 2,123 fish, representing 24 different species were killed along nine miles of Durbin Creek. From an overall standpoint, the response to this incident was sufficient to protect human health and minimize environmental damage. Contingency planning had prepared CPC for a spill of this magnitude and resources committed to the cleanup were adequate to accomplish the removal of the spilled product. The RRT concept proved to be of valuable assistance to the OSC from a resource perspective; and implementing the organizational components of the RRT provided the necessary mechanism for input and decision making for various parties affected by this incident

    Most of the pipelines of oil and gas pipelines in our country have been for more than 25 years. These pipes are buried underground and was difficult to daily test. In addition, it was vulnerable to environmental, corrosion and natural disasters, So there is a hidden nature of accidents. The rapid development of urbanization, population accumulation, dense building and insufficient safety range are all the reasons for the frequent accidents of oil and gas pipelines. Therefore, to appraise and know the safe condition of the city various regions oil and gas pipelines is vital significant. In order to ensure the safety of oil and gas pipeline city, this paper defines the connotation of oil and gas pipeline city vulnerability according to the previous research on vulnerability. Then from three perspectives of environment, structure and behavior, based on the analytical paradigm of “structure—vulnerability conduct—performance” about oil and gas, the influential indicators of vulnerable oil and gas pipelines were analysed, the vulnerability mechanism framework of Oil and gas pipeline city was also constructed. Finally, the paper proposed the regulating strategy of the vulnerability of the oil and gas pipeline city to decrease its vulnerability index, which can be realize the city’s vulnerability evaluation and provides new ideas for the sustainable development of the city.

    Microbiologically influenced corrosion is a problem commonly encountered in facilities in the oil and gas industries. The present study describes bacterial enumeration and identification in diesel and naphtha pipelines located in the northwest and southwest region in India, using traditional cultivation technique and 16S rDNA gene sequencing. Phylogenetic analysis of 16S rRNA sequences of the isolates was carried out, and the samples obtained from the diesel and naphtha-transporting pipelines showed the occurrence of 11 bacterial species namely Serratia marcescens ACE2, Bacillus subtilis AR12, Bacillus cereus ACE4, Pseudomonas aeruginosa AI1, Klebsiella oxytoca ACP, Pseudomonas stutzeri AP2, Bacillus litoralis AN1, Bacillus sp., Bacillus pumilus AR2, Bacillus carboniphilus AR3, and Bacillus megaterium AR4. Sulfate-reducing bacteria were not detected in samples from both pipelines. The dominant bacterial species identified in the petroleum pipeline samples were B. cereus and S. marcescens in the diesel and naphtha pipelines, respectively. Therefore, several types of bacteria may be involved in biocorrosion arising from natural biofilms that develop in industrial facilities. In addition, localized (pitting) corrosion of the pipeline steel in the presence of the consortia was observed by scanning electron microscopy analysis. The potential role of each species in biofilm formation and steel corrosion is discussed. (orig.)

    1977-07-29

    The objective of the work reported here was to develop a model which could be used to assess the economic effects of energy-conservative technological innovations upon the pipeline industry. The model is a dynamic simulator which accepts inputs of two classes: the physical description (design parameters, fluid properties, and financial structures) of the system to be studied, and the postulated market (throughput and price) projection. The model consists of time-independent submodels: the fluidics model which simulates the physical behavior of the system, and the financial model which operates upon the output of the fluidics model to calculate the economics outputs. Any of a number of existing fluidics models can be used in addition to that developed as a part of this study. The financial model, known as the Systems, Science and Software (S/sup 3/) Financial Projection Model, contains user options whereby pipeline-peculiar characteristics can be removed and/or modified, so that the model can be applied to virtually any kind of business enterprise. The several dozen outputs are of two classes: the energetics and the economics. The energetics outputs of primary interest are the energy intensity, also called unit energy consumption, and the total energy consumed. The primary economics outputs are the long-run average cost, profit, cash flow, and return on investment.

    2006-07-01

    Moving biomass and energy through pipelines was presented. Field sourced biomass utilization for fuel was discussed in terms of competing cost factors; economies of scale; and differing fuel plant sizes. The cost versus scale in a bioenergy facility was illustrated in chart format. The transportation cost of biomass was presented as it is a major component of total biomass processing cost and is in the typical range of 25-45 per cent of total processing costs for truck transport of biomass. Issues in large scale biomass utilization, scale effects in transportation, and components of transport cost were identified. Other topics related to transportation issues included approaches to pipeline transport; cost of wood chips in pipeline transport; and distance variable cost of transporting wood chips by pipeline. Practical applications were also offered. In addition, the presentation provided and illustrated a model for an ethanol plant supplied by truck transport as well as a sample configuration for 19 truck based ethanol plants versus one large facility supplied by truck plus 18 pipelines. Last, pipeline transport of bio-oil and pipeline transport of syngas was discussed. It was concluded that pipeline transport can help in reducing congestion issues in large scale biomass utilization and that it can offer a means to achieve large plant size. Some current research at the University of Alberta on pipeline transport of raw biomass, bio-oil and hydrogen production from biomass for oil sands and pipeline transport was also presented. tabs., figs.

    2009-03-01

    This report discussed an oil spill which occurred in July 2007 when a contractor's excavator bucket punctured a pipeline during the excavation of a trench for a new storm sewer line at a location in Burnaby, British Columbia (BC). The puncture caused the release of approximately 234 cubic meters of crude oil, which flowed into Burrard Inlet Bay via a storm sewer system. Eleven houses were sprayed with crude oil, and many other properties required restoration. Approximately 250 residents left their homes. While emergency workers and firefighters responding to the incident were sprayed with crude oil, no explosions, fires, or injuries occurred. The report provided details of studies conducted to determine the placement of the sewer line, as well as attempts made by the contractors to determine the lateral connection of the crude oil pipeline. Discrepancies between the location of the pipeline design drawing and its actual location on other construction drawings were also noted by the contractor. Twenty-four minutes after the rupture, the terminal was fully isolated and the drain-down of the pipeline was completed within an hour. The cause of the accident was attributed to inaccurate construction drawings and inadequate communications between contractors and consulting companies. 3 figs

    2004-01-01

    At the start of the 1990s there were concerns over the increasing threat of corrosion to the integrity of high-pressure oil and gas transmission pipelines. For example: corrosion was the major cause of reportable incidents in North America (1]. Corrosion was the major cause of pipeline failure in the Gulf of Mexico [2]. Corrosion in a North American onshore oil pipeline had required over $1 billion in repairs(3]. Internal corrosion along the complete length of pipelines had resulted in replacement[4] . However, the worldwide published failure statistics indicate that the incidents of corrosion are not increasing year on year(5-9]. Indeed, CONCA WE[8,9] statistics (for pipelines In Western Europe) show that the failure rate from corrosion (the most likely failure mode with increasing age) has not increased with pipeline age (Figure 1). In fact the statistics for gas pipelines in Europe

    Two thermophilic archaea, strain PK and strain MG, were isolated from a culture enriched at 80°C from the inner surface material of a hot oil pipeline. Strain PK could ferment complex organic nitrogen sources (e.g. yeast extract, peptone, tryptone) and was able to reduce elemental sulfur (S°), Fe(3+) and Mn(4+) . Phylogenetic analysis revealed that the organism belonged to the order Thermococcales. Incubations of this strain with elemental iron (Fe°) resulted in the abiotic formation of ferrous iron and the accumulation of volatile fatty acids during yeast extract fermentation. The other isolate, strain MG, was a H(2) :CO(2) -utilizing methanogen, phylogenetically affiliated with the genus Methanothermobacter family. Co-cultures of the strains grew as aggregates that produced CH(4) without exogenous H(2) amendment. The co-culture produced the same suite but greater concentrations of fatty acids from yeast extract than did strain PK alone. Thus, the physiological characteristics of organisms both alone and in combination could conceivably contribute to pipeline corrosion. The Thermococcus strain PK could reduce elemental sulfur to sulfide, produce fatty acids and reduce ferric iron. The hydrogenotrophic methanogen strain MG enhanced fatty acid production by fermentative organisms but could not couple the dissolution Fe° with the consumption of water-derived H(2) like other methanogens. © 2012 Society for Applied Microbiology and Blackwell Publishing Ltd.

    2016-09-01

    Multipurpose pipeline is often seriously corroded during its service life, and the phenomenon is more prominent once the transportation medium is changed. Electrochemical polarization curves and impedance spectroscopy of the API 5L Gr. X60 steel pipeline's corrosion process in sedimentary water with different ion types and their concentrations have been studied in this work. The results showed that the corrosion rates were found to be 0.00418 and 0.00232 mm/a for pure water and crude oil, respectively. However, for the mixtures of water and crude oil (with water content increased from 0.2 vol% to 10 vol%), the corrosion rate increased consistently and reached a maximum value of 0.15557 mm/a for 10 vol% water in crude oil. The effect of the concentration of various ions, namely, chloride, bicarbonate and sulfate in (oil/water) mixtures on the corrosion rate was characterized by weight-loss method. The results showed that with increasing the ions' concentrations, the corresponding exchange current density increased significantly. The results were further supported by the observations of corrosion morphology using scanning electron microscopy and are helpful in devising guidelines which would help in reducing corrosion in multipurpose transport pipelines involving a change of transported medium during their service life.

    2004-07-01

    The reliability of a land pipeline operated by PEMEX in Mexico was estimated under a range of failure modes. Reliability and safety were evaluated in terms of the pipeline's internal pressure, bending, fracture toughness and its tension failure mode conditions. Loading conditions were applied individually, while bending and tension loads were applied in a combined fashion. The mechanical properties of the steel were also considered along with the degradation effect of internal corrosion resulting from the type of product being transported. A set of internal pressures and mechanical properties were generated randomly using Monte Carlo simulation. Commercial software was used to obtain the pipeline response under each modeled condition. The response analysis was based on the nonlinear finite element method involving a calculation of maximum stresses and stress concentration factors under conditions of corrosion and no corrosion. The margin between maximum stresses due to internal pressure, tension and bending was evaluated along with the margin between stress concentration factor and fracture initiation toughness. The study showed that internal pressure, stress concentration and tension-bending were the critical failure modes. It was suggested that more research should be conducted to improve the modeling of the deteriorating effects of corrosion and to adjust the probability distribution for fracture toughness and the length/depth defect ratio. The consideration of welding geometries along with features of marine pipelines and pipeline products would help to generalize the study to facilitate the creation of codes for the construction, design, inspection and maintenance of pipelines in Mexico. 7 refs., 1 tab., 14 figs.

    1993-01-01

    A road grader punctured a high-pressure crude oil pipeline in the California high desert resulting in the release of approximately 4,200 barrels of Alaska North Slope crude oil. Oil sprayed over a steeply sloped hillside and flowed into an adjacent, densely vegetated ephemeral stream channel which carried secondary treatment sewage discharge. Three underflow dams were constructed in the channel within 2.8 km of the site. To ensure containment at the first dam, the sewage discharge was diverted from the channel, eventually to an upland impulse sprinkler irrigation system. Channel water and phase-separated ANS crude oil, impounded behind the first dam, percolated through alluvial sands/gravels to a depth of about five meters. The oil percolated through the soils on the receding surface of the water, affecting soils to an equivalent depth and saturating a horizontally narrow band of stream-bank soils as much as two to four meters into the bank. Stream channel undergrowth and a small number of mature trees were cleared to provide access for cleanup and/or to remove oiled plants. A large number of trees experienced partial leaf-drop within 25 days of the spill while two heavily oiled trees died. New vegetative growth was evident within five weeks of the spill. Site restoration included planting cuttings of five riparian tree species and hydroseeding exposed banks. Total petroleum hydrocarbon concentrations ranged from not detectable to 203,000 parts per million and averaged approximately 25,000 ppm in affected soils as sampled in place and in stockpiles. Approximately 30,000 tons of hydrocarbon-contaminated soil was excavated from the length of the stream channel (3,600 tons) as well as the area behind the first dam and spill site (26,400 tons). All soils were staged on site for waste profiling and final disposition. After treatment, the contaminated soil was beneficially reused as daily cover at a southern California landfill at a turnkey cost of approximately $57/ton

    Mexico has a very important oil industry, comprehending the exploration, production, transformation, storage and distribution of crude oil and its fractions. Petroleos Mexicanos (PEMEX) is a state-owned monopoly in charge of these activities. Oil and oil-products transport is an extremely crucial operation for the cycle production-transformation-distribution. Pipeline system transport crude oil and sub-products along the country (including liquids, gases and mixtures). It has been reported that more than 30% of the oil ducts in Mexico have been operating for over 30 years, although their lifetime has been calculated in 25-30 years. This work is aimed at characterizing a zone around six oil-pipeline pumping stations located at northern Mexico. The specific places to evaluate soil contamination were (1) the distribution head of the Gomez Palacio (GOPA) pumping station; (2) the north side of the old ditch, the API oil separator and the wastewater zones of the Jimenez (JIM) pumping station; (3) the pumping stations of Ceballos (CE), Peronal (PER), Simon Bolivar (SIBO), and Mayran (MAY). The study comprehended sampling of the areas, delimitation of contamination in the vertical and horizontal extension, analysis of the sampled soils, regarding TPH and, in some cases, the 16 PAHs considered as a priority by USEPA, calculation of areas and volumes contaminated (according to the Mexican legislation, specifically NOM-EM-138-ECOL-2002) and, finally, a proposal for the best remediation techniques suitable for the encountered contamination levels and the localization of contaminants. In general, TPHs were found in all the pumping stations analyzed in this study. Regarding maximal TPHs concentrations at the stations, their order of contamination was as follows: SIBO>CE>PER>MAY>JIM>GOPA. PAHs were found only in a few points at concentrations above the detection limit. At the Jimenez, Gomez Palacio, Peronal, and Ceballos stations, only one point, with PAHs values over the

    Full Text Available Oil and gas pipelines are the infrastructure of national economic development. Deployment problem of wireless underground sensor networks (WUSN for oil and gas pipeline systems is a fundamental problem. This paper firstly analyzed the wireless channel characteristics and energy consumption model in near-surface underground soil, and then studied the spatial structure of oil and gas pipelines and introduced the three-layer system structure of WUSN for oil and gas pipelines monitoring. Secondly, the optimal deployment strategy in XY plane and XZ plane which were projected from three-dimensional oil and gas pipeline structure was analyzed. Thirdly, the technical framework of using kinetic energy of the fluid in pipelines to recharge sensor nodes and partition strategy for energy consumption balance based on the wireless communication technology of magnetic induction waveguide were proposed, which can effectively improve the energy performance and connectivity of the network, and provide theoretical guidance and practical basis for the monitoring of long oil and gas pipeline network, the city tap water pipe network and sewage pipe network.

    Full Text Available A commercially available ASPEN PLUS simulation using a pipe model was employed to determine the maximum safe pipeline distances to subsequent booster stations as a function of carbon dioxide (CO2 inlet pressure, ambient temperature and ground level heat flux parameters under three conditions: isothermal, adiabatic and with account of heat transfer. In the paper, the CO2 working area was assumed to be either in the liquid or in the supercritical state and results for these two states were compared. The following power station data were used: a 900 MW pulverized coal-fired power plant with 90% of CO2 recovered (156.43 kg/s and the monothanolamine absorption method for separating CO2 from flue gases. The results show that a subcooled liquid transport maximizes energy efficiency and minimizes the cost of CO2 transport over long distances under isothermal, adiabatic and heat transfer conditions. After CO2 is compressed and boosted to above 9 MPa, its temperature is usually higher than ambient temperature. The thermal insulation layer slows down the CO2 temperature decrease process, increasing the pressure drop in the pipeline. Therefore in Poland, considering the atmospheric conditions, the thermal insulation layer should not be laid on the external surface of the pipeline.

    2015-01-01

    Full Text Available This article reveals the practice of "ship or pay" principle in the US, Canada and Europe. The authors analyze the practice of concluding contracts for oil and petroleum products transportation, procedures, terms and conditions stipulated in the contract. The "take or pay" principle is a common practice in developed countries like the US, Canada and the UK. The specific feature of the United States is that the pipelines are not built only for one shipper, but rather for all market, which is caused the "open season" tradition. In Canada, "take or pay" principle applies to cover the capital costs of the carrier. The main reasons for usage of terms "take or pay" are to minimize risks of the carrier, building or expanding his own pipeline network, by guaranteeing shipper's financial benefits after the putting pipeline into operation. "Take or pay" contracts cover the carrier's obligation to provide agreed minimum amount of petroleum to the consignor within a certain period. In turn, the shipper is obliged to accept the minimum amount of petroleum and pay, regardless of the fact of acceptance of oil. "Take or pay" principle is a kind of risk-sharing mechanism, which allows to shift the risks of non-fulfillment of the contract to the shipper. Besides, the "take or pay" principle can be indirect guarantee in the context of project financing, and therefore, financing. The article emphasizes the main advantages of the application of this principle and opportunities for its use in Russia.

    Oil sands transportation diversification is important for preventing discounted crude pricing. Current life cycle assessment (LCA) models that assess greenhouse gas (GHG) emissions from crude oil transportation are linearly-scale and fail to account for project specific details. This research sets out to develop a detailed LCA model to compare the energy inputs and GHG emissions of pipeline and rail transportation for oil sands products. The model is applied to several proposed oils sands transportation routes that may serve as future markets. Comparison between transportation projects suggest that energy inputs and GHG emissions show a high degree of variation. For both rail and pipeline transportation, the distance over which the product is transported has a large impact on total emissions. The regional electricity grid and pump efficiency have the largest impact on pipeline emissions, while train engine efficiency and bitumen blending ratios have the largest impact on rail transportation emissions. LCA-based GHG regulations should refine models to account for the range of product pathways and focus efforts on cost-effective emission reductions. As the climate-change impacts of new oil sands transportation projects are considered, GHG emission boundaries should be defined according to operation control. -- Highlights: •A life cycle model is developed to compare transportation of oil sands products. •The model is applied to several potential future oil sands markets. •Energy inputs and GHG emissions are compared. •Model inputs are explored using sensitivity analysis. •Policy recommendations are provided

    Trace amounts of vanadium in crude oil and in heavy distillate fuels are very harmful due to their corrosive action. Thus the necessity arises for continuous control of the vanadium content in oil pipelines. Moreover, the development of a nuclear on-line sensor that can continuously analyze the vanadium content in oil pipelines may lead to a better control of processing operations. In this paper a feasibility study for on-line analysis of vanadium in crude oil by means of neutron activation analysis is presented. (author)

    Incrustations can be defined as chemical compounds organic, inorganic and mixed, initially insoluble, and which precipitate accumulating in the internal wall of pipes, surface equipment and/or parts of components involved in the production and transport of oil. These compounds, when precipitating, cause problems in the oil industry and consequently result in losses in the optimization of the extraction process. Although the importance and impact of the precipitation of these compounds in the technological and economic scope, there is still the difficulty in determining methods that enable the identification and quantification of the incrustations at an initial stage. The use of the gamma transmission technique may provide support for a better understanding of the deposition of these compounds, making it a suitable tool for the non-invasive determination of their deposition in oil transport pipelines. The geometry used for the incrustations detection include a 280 mm diameter steel pipe containing barium sulphide incrustations (BaSO 4 ) ranging from 5 to 80 mm, a gamma radiation source with divergent beam and as NaI(Tl) 2 x 2” scintillation detector. The opening size of the collimated beam was evaluated (2 to 7 mm) to also quantify the associated error in calculating the incrustations. The study was realized with computer simulation, using the MCNP-X code and validated by means of analytical equations that indicate the possibility of using this study for this purpose. (author)

    Yeeles, Adam; Akporiaye, Alero

    2016-01-01

    Political unrest in the Niger Delta has long been viewed as a hurdle for extracting maximum value from Nigeria's oil resources. Recently, investors and policymakers have laid blame for sector under-performance on pipeline sabotage and theft, and sounded the alarm for an impending ‘oil crisis’. However, our understanding of the economic effects of social action against oil companies is incomplete. Rigorous analysis has not heretofore been offered as evidence for such dire futures. Despite the obvious risk of pipeline interdiction, price dynamics and aggregate production respond minimally to pipeline interdiction. Based on quantitative analysis of the relationship among price, production and pipeline interdiction from multiple data sources covering different time intervals (monthly data from 2005 to 2014 and annual data from 1999 to 2013), we find no evidence of significant effects of pipeline interdiction on production and a weak relationship between pipeline interdiction and Bonny light crude prices. Reported losses in product are substantial, but there is no evidence of statistically significant impacts on price or production in the aggregate. Explanations for this counterintuitive result are cast in terms of sector resilience. The implications of this finding for producer risk and the likelihood of an impending ‘oil crisis’ are discussed. - Highlights: • We examine the impact of pipeline sabotage and theft on the Nigerian oil economy. • Econometric analysis of production, price and pipeline interdiction over different time intervals. • Aggregate price and production are impacted minimally by pipeline interdiction. • Oil sector business risk is high, but production is resilient to interruptions from social and political unrest.

    1979-01-01

    CONCAWE's annual report on oil industry cross-country pipelines in Western Europe shows that in 1978 the pipeline network reached a combined length of 18,500 kilometres and transported 594 million cubic metres of crude oil and refined products. The gross spillage amounted to 3639 m/sup 3/, that is 0.000613 percent or about 6.1 parts per million of the total quantity transported. The net spillage loss was 1,377 m/sup 3/ since 2,262 m/sup 3/ were recovered at site. There were 15 spillage incidents reported during 1978, all of which were directly related to pipelines (none to pump-stations). In 4 incidents the oil spilled was completely recovered, and in 10 cases clean-up was completed within one week of the discovery of the spillage. No contamination of potable water sources was reported. The causes of the spillages are attributed to corrosion (7 incidents), third party activities (4), mechanical failure (3) and natural hazards, i.e. excessive rainfall (1). The report also gives a comparison for the five-year period 1974 to 1978.

    Although oil leaks from pipelines are less dangerous than a blowout of oil as a result of a pipeline break, the presence of oil in the ocean can have a devastating affect on the marine environment, particularly as oil leaks are difficult to detect and can occur over long periods of time. This paper discussed oil pollution in the Bohai Sea. Most of the crude oil in the Bohai oil fields is heavy and contains both paraffin and sand, both of which contribute to greater incidences of cracks and corrosion wormholes in pipes. The Main Points of Model for Assessment of Environmental Consequence of the Oil Leaks from Marine Pipeline (MAECOLMP) is based on the assumption that oil leaks from wormholes on seabed pipelines generate separate oil drops which float up to create a plume in the water. After their emergence on the sea surface, an oil slick forms, which has the shape of a serpentine strip extending along the surface in the direction of the current. The main parameters that define environmental oil pollution are: the dimensions of oil drops in the water; the dimension of the oil slick on the sea surface; and the carryover of crude oil on the coastline. According to the model, the assessment of environmental effects of the oil leaks from the sea bed consist of the following stages: selection of the probable position of wormholes in the pipeline and their size; calculation of the rate of the oil leak from the wormhole for selected sizes and positions; estimation of probable average sizes of oil drops for the selected diameter of wormhole; calculation of boundaries of the plume; calculation of the width and extension of the oil slicks for each selected position of the wormhole; and estimation of the volume of crude oil that can be carried over to the coastline in each case and detection of the most dangerous accident variant. This model permits the use of the Lagrangian description in order to take into account the difference in the velocities of emerging oil drops. It

    The overhead transmission of large amounts of electricity over long distances requires high transmission voltages which can generate high electric fields that may have harmful effects on both human and animals. Therefore, corridors or right-of-way are left on both sides along the route of transmission lines. Overhead power transmission lines need strips of land to be designated as rights-of-way. These strips of land can also support other uses such as pipelines, railroads and highways. The primary purpose for minimizing the field effects of high voltage AC lines is to reduce the electric field at ground level. This study investigated the effects of oil-pipelines running parallel to the lines in the rights-of-way corridors on the electric fields generated from high voltage electrical networks in Kuwait. In order to examine the impact of certain design parameters on the electric field distribution near the ground surface, this study varied the oil pipelines diameter, the proximity of the pipeline from the transmission line center and the number of pipelines. The objective was to determine if the amount of land which is required as right-of-way can be reduced. This study also examined the effect of two parallel oil pipelines on the field distribution. Both pipelines were separated by a given distance and ran parallel to the transmission line conductors. The charge simulation method (CSM) was used to simulate and model both the conductors of the transmission lines and the oil-pipelines. Graphs for the electric field distribution profiles at the ground surface, at transmission line conductors' surfaces and at the surfaces of the oil pipelines were presented and evaluated for each scenario. 10 refs., 12 figs.

    Throughout the historic evolution of the Brazilian legislation, including a brief analysis of the prevailing laws regarding the subject, this paper provides an ample vision of the civil and environmental liability in transport contracts, and, especially, in the transport of oil and gas through pipelines, discussing the present influence of environmental norms and the New Brazilian Civil Code. And what was brought to a conclusion is, if on one hand were kept the liability of the Sender (user company of the transportation service contracted with the Carrier) and Carrier (personal entity operator of the pipeline system), who respond jointly and regardless of fault for damages to third parties and the environment (extendible also to the owner of the product and to financial institutions that participate in some form in the contract), on the other hand the New Civil Code authorizes the National Petroleum Agency - ANP to rule the liabilities between the parties to the transport contract, providing greater safety to the system operators.

  17. The transit oil and gas pipeline and the role of bargaining: A non-technical discussion

    Transit oil and gas pipelines are growing in relevance, and face a number of topical problems. One of such issues is the problem of potential disruption from a number of sources, notably post-construction behaviour of the transit country. Present and future pipelines face the risk of continuous conflict over legal, economic and political issues. Once the pipeline is built and in operation, the threat of disruption of the pipeline by the transit country over disputed transit terms exists. This is due to two key problems: first, a shift in bargaining powers to the transit country upon construction and operation of the pipeline and, second, changes in the value of the throughput imply price changes that can affect the behaviour of the transit country. This paper discusses the role of basic bargaining principles in cross-border oil and gas pipelines involving transit through one or more countries. It finds that the motive behind the pipeline plays a key role in the prevention of potential disruptions to the pipeline due to rent squeezing. Also, although the potential of such disruptions does exist, there are a number of factors that could serve to mute the consequences of shifts in bargaining power to the transit countries

    Our purpose is to focus on the Safety, Environment and Health (SEH) Management, integrated to pipeline construction and assembly, aiming at minimizing the risks involving the transportation and handling of 20-inch pipes. Please note that peculiar, challenging situations occur when constructing a gas pipeline at the Coari-Anama Section, which leads to some difficulty in the exploitation of oil and gas, where fragile elements represented by the environment and man are faced in this evolution and progress process. Overcoming the severe conditions while streaming 196.6-km-length of pipes in flooded lands no doubt represented a real challenge. State-of-the-art techniques have been implemented such as air transportation of pipes, with two large-sized helicopters being used (Kamov and S64 Skycrane). This has demanded integrated actions to be adopted, involving transportation of concrete pipes, double joints, pipesak, hydraulic excavators, net carrier containing assorted materials, skids and natural gas pressure, measurement and filtering equipment. Nevertheless, we have succeeded in reducing the rate of exposure to the construction and assembly process risks, thus minimizing occurrences and improving the conditions of processes, where, had the conventional method been used, would have led to a great amount of incidents and accidents, resulting mainly from the huge logistic difficulties, which would expose the task force to high potential risks.

    According to the existing prognoses more than 1 million km of gas pipelines, oil pipelines and water pipelines are built up to the year 2030. The predominant portion is from gas pipelines. The safe continued utilization of the aging pipelines is a large challenge. In addition, the diagnostic technology, the evaluation and risk assessment have to be developed further. With the design of new oil pipelines and gas pipelines, aspects of environmental protection, the energy efficiency of transport and thus the emission reduction of carbon dioxide, the public acceptance and the market strategy of the exporters gain in importance. With the offshore pipelines one soon will exceed the present border of 2,000 m depth of water and penetrate into larger sea depths.

    CONCAWE has collected 39 years of spillage data on European cross-country oil pipelines. At about 35,000 km the inventory covered currently includes the vast majority of such pipelines in Europe, transporting around 870 million m3 per year of crude oil and oil products. This report covers the performance of these pipelines in 2009 and a full historical perspective since 1971. The performance over the whole 39 years is analysed in various ways including gross and net spillage volumes and spillage causes grouped into five main categories: mechanical failure, operational, corrosion, natural hazard and third party. The rate of inspections by in line tools (intelligence pigs) is also reported. 5 spillage incidents were reported in 2009, corresponding to 0.14 spillages per 1000 km of line, well below the 5-year average of 0.28 and the long-term running average of 0.53, which has been steadily decreasing over the years from a value of 1.2 in the mid 70s. There were no fires, fatalities or injuries connected with these spills. 4 incidents were due to mechanical failure and 1 was connected to past third party activities. Over the long term, third party activities remain the main cause of spillage incidents although mechanical failures have increased in recent years, a trend that needs to be scrutinised in years to come.

There were no fires, fatalities or injuries connected with these spills. 7 incidents were due to mechanical failure, 1 incident to corrosion and 4 were connected to third party activities. Over the long term, third party activities remain the main cause of spillage incidents although mechanical failures have increased in recent years, a trend that needs to be scrutinised in years to come.

    CONCAWE has collected 39 years of spillage data on European cross-country oil pipelines. At about 35,000 km the inventory covered currently includes the vast majority of such pipelines in Europe, transporting around 870 million m3 per year of crude oil and oil products. This report covers the performance of these pipelines in 2009 and a full historical perspective since 1971. The performance over the whole 39 years is analysed in various ways including gross and net spillage volumes and spillage causes grouped into five main categories: mechanical failure, operational, corrosion, natural hazard and third party. The rate of inspections by in line tools (intelligence pigs) is also reported. 5 spillage incidents were reported in 2009, corresponding to 0.14 spillages per 1000 km of line, well below the 5-year average of 0.28 and the long-term running average of 0.53, which has been steadily decreasing over the years from a value of 1.2 in the mid 70s. There were no fires, fatalities or injuries connected with these spills. 4 incidents were due to mechanical failure and 1 was connected to past third party activities. Over the long term, third party activities remain the main cause of spillage incidents although mechanical failures have increased in recent years, a trend that needs to be scrutinised in years to come.

    Pipelines are usually buried and have the function of long-distance transport. For this, special safety measures are requires. For example, pipelines of the chemical industry have defined locations that must be easily identifiable. Pipelines must be adapted to infrastructural and topographic boundary conditions, in consideration of environmental protection and because the pipeline may be damaged by external influences. Even minor releases of chemical substances may pollute water and soil and cause damage to humans. The contribution discusses the possible damage resulting from a pipeline leak. (orig.)

    A major problem about the planning of production in refinery is the determination of what should be done in each stage of production as a horizon of time. Among such problems, distribution of oil products through networks of pipelines is a very significant problem because of its economic importance. In this work, a problem of distribution of oil through a network of pipelines is modeled. The network studied is a simplification of a real network. There are several restrictions to be met, such as limits of storage, transmission or receipt of limits and limitations of transport. The model is adopted bi-goal where you want to minimize the fragmentation and the time of transmission, given the restrictions of demand and storage capacity. Whereas the occupancy rate of networks is increasingly high, is of great importance optimize its use. In this work, the technique of optimization by Cloud of particles is applied to the problem of distribution of oil products by networks of pipelines. (author)

    Full Text Available Constructive, technical and technological reliability of major pipeline ensures ecological safety on different stages of life circle - beginning with project preparation activities up to the end of major pipeline operation. Even in the process of transition into new life circle stage, no matter if the pipeline needs major repairs or reconstruction, such technical and technological solutions should be found, which would preserve ecological stability of nature-anthropogenic system. Development of ecology protection technologies of construction, reconstruction and major repairs of main pipelines is of great importance not only for a region, but ensures ecological safety across the globe. The article presents a new way of trenching the main oil and gas pipeline, preservation and increase of ecological safety during its service. The updated technological plan is given in the paper for overhaul of the main oil and gas pipeline using the new technology of pipeline trenching. The suggested technical solution contributes to environment preservation with the help of deteriorating shells - the shells’ material decomposes into environment-friendly components: carbon dioxide, water and humus. The quantity of polluting agents in the atmosphere decreases with the decrease of construction term and quantity of technical equipment.

    Although the multiple roles of wetland ecosystems and their value to humanity have been increasingly understood and documented in recent years, the efforts to conserve and restore wetlands are not in harmony with the press for high speed of economy growth. The degradation of wetlands is proceeding, especially in China. Russia- China Oil Pipe-line Project (Mohe-Daqing Section) has already begun in May 2009, and is ongoing. The pipeline runs through four riverine wetlands and two marshlands of Heilongjiang Province, Northeast China. Although the project has vital significance of mitigating the energy crisis as well as guaranteeing the energy security of China, it will bring a series of ecological and environmental problems, especially for wetland ecosystems

    A method is presented for construction of hydraulic characteristics of sections of an oil pipeline by pattern recognition methods. In the theory of pattern recognition, the characteristics of a complex object are studied by means of adaptation algorithms. These algorithms allow the generation of models of processes, establishment of the relationships between their defining parameters and output characteristics on the basis of successive processing of information on the object (for example, dispatchers data on a pipeline sector). The analysis does not require analytic formalization of the processes. This work presents a solution of the problem of determination of the pressure loss to friction over the sections of a main pipeline on the basis of the following initial data: oil flowrate, diameter of pipeline, length of section, and viscosity of oil. The range of change of the pressure drop is divided into intervals (classes), and the task of determination of the continuous value is reduced to recognition of its membership in one of the classes with an accuracy equal to the size of an interval. The potential functions method from pattern recognition theory is used to perform the classification. The algorithm presented allows actual operational characteristics of main oil pipelines to be defined with an accuracy sufficient for practical application.

    Full Text Available Lowering uncertainty in crude oil volume measurement has been widely considered as one of main purposes in an oil export terminal. It is found that crude oil temperature at metering station has big effects on measured volume and may cause big uncertainty at the metering point. As crude oil flows through an aboveground pipeline, pick up the solar radiation and heat up. This causes the oil temperature at the metering point to rise and higher uncertainty to be created. The amount of temperature rise is depended on exterior surface paint color. In the Kharg Island, there is about 3 km distance between the oil storage tanks and the metering point. The oil flows through the pipeline due to gravity effects as storage tanks are located 60m higher than the metering point. In this study, an analytical model has been conducted for predicting oil temperature at the pipeline exit (the metering point based on climate and geographical conditions of the Kharg Island. The temperature at the metering point has been calculated and the effects of envelope color have been investigated. Further, the uncertainty in the measurement system due to temperature rise has been studied.

    The gas pipeline networks in Sichuan and Chongqing (Sichuan-Chongqing) region have formed a fully-fledged gas pipeline transportation system in China, which supports and promotes the rapid development of gas market in Sichuan-Chongqing region. In the circumstances of further developed market-oriented economy, it is necessary to carry out further the pipeline system reform in the areas of investment/financing system, operation system and pricing system to lay a solid foundation for improving future gas production and marketing capability and adapting itself to the national gas system reform, and to achieve the objectives of multiparty participated pipeline construction, improved pipeline transportation efficiency and fair and rational pipeline transportation prices. In this article, main thinking on reform in the three areas and major deployment are addressed, and corresponding measures on developing shared pipeline economy, providing financial support to pipeline construction, setting up independent regulatory agency to enhance the industrial supervision for gas pipeline transportation, and promoting the construction of regional gas trade market are recommended.

  15. Leak Detection Modeling and Simulation for Oil Pipeline with Artificial Intelligence Method

    Directory of Open Access Journals (Sweden)

    Pudjo Sukarno

    2007-05-01

    Full Text Available Leak detection is always interesting research topic, where leak location and leak rate are two pipeline leaking parameters that should be determined accurately to overcome pipe leaking problems. In this research those two parameters are investigated by developing transmission pipeline model and the leak detection model which is developed using Artificial Neural Network. The mathematical approach needs actual leak data to train the leak detection model, however such data could not be obtained from oil fields. Therefore, for training purposes hypothetical data are developed using the transmission pipeline model, by applying various physical configuration of pipeline and applying oil properties correlations to estimate the value of oil density and viscosity. The various leak locations and leak rates are also represented in this model. The prediction of those two leak parameters will be completed until the total error is less than certain value of tolerance, or until iterations level is reached. To recognize the pattern, forward procedure is conducted. The application of this approach produces conclusion that for certain pipeline network configuration, the higher number of iterations will produce accurate result. The number of iterations depend on the leakage rate, the smaller leakage rate, the higher number of iterations are required. The accuracy of this approach is clearly determined by the quality of training data. Therefore, in the preparation of training data the results of pressure drop calculations should be validated by the real measurement of pressure drop along the pipeline. For the accuracy purposes, there are possibility to change the pressure drop and fluid properties correlations, to get the better results. The results of this research are expected to give real contribution for giving an early detection of oil-spill in oil fields.

    Safe and financially efficient pipeline transportation of carbon dioxide is a critical issue in the developing field of the CCS Technology. In this part of the process, carbon dioxide is transported via pipes with diameter of 1.5 m and entry pressure of 150 bar, with Reynolds number of 107 and viscosity of 8×10(-5) Pa.s as dense fluid [1]. Presence of large and small scale structures in the pipeline, high Reynolds numbers at which CO2 should be transferred, and 3 dimensional turbulence caused by local geometrical modifications, increase the importance of simulation of turbulent material transport through the individual components of the CO2 chain process. In this study, incompressible turbulent channel flow and pipe flow have been modeled using OpenFoam, an open source CFD software. In the first step, simulation of a turbulent channel flow has been considered using LES for shear Reynolds number of 395. A simple geometry has been chosen with cyclic fluid inlet and outlet boundary conditions to simulate a fully developed flow. The mesh is gradually refined towards the wall to provide values close enough to the wall for the wall coordinate (y+). Grid resolution study has been conducted for One-Equation model. The accuracy of the results is analyzed with respect to the grid smoothness in order to reach an optimized resolution for carrying out the next simulations. Furthermore, three LES models, One-Equation, Smagorinsky and Dynamic Smagorinsky are applied for the grid resolution of (60 × 100 × 80) in (x, y, z) directions. The results are then validated with reference to the DNS carried out by Moser et al.[2] for the similar geometry using logarithmic velocity profile (U+) and Reynolds stress tensor components. In the second step the similar flow is modeled using Reynolds averaged method. Several RANS models, like K-epsilon and Launder-Reece-Rodi are applied and validated against DNS and LES results in a similar fashion. In the most recent step, it has been intended

    2014-01-01

    This paper explores the response by members of the lay public to the prospect of an onshore CO 2 pipeline through their locality as part of a proposed CCS development and presents results from deliberative Focus Groups held along a proposed pipeline route. Although there is a reasonable level of general knowledge about CO 2 across the lay public, understanding of its specific properties is more limited. The main concerns expressed around pipelines focused on five areas: (i) safe operation of the pipeline; (ii) the risks to people, livestock and vegetation arising from the leakage of CO 2 from the pipeline; (iii) the innovative and ‘first of its kind' nature of the pipeline and the consequent lack of operational CO 2 pipelines in the UK to demonstrate the technology; (iv) impacts on coastal erosion at the landfall site; and (v) the potential disruption to local communities during pipeline construction. Participants expressed scepticism over the motivations of CO 2 pipeline developers. Trust that the developer will minimise risk during the route selection and subsequent construction, operation and maintenance of the pipeline is key; building trust within the local community requires early engagement processes, tailored to deliver a variety of engagement and information approaches. - Highlights: • Lay publics express good general knowledge of CO 2 but not of its specific properties. • Key concerns relate to risk and safety and ‘first of a kind' nature of CO 2 pipeline. • Group participants are sceptical about motivations of CO 2 pipeline developers. • Communities' trust in developer is a major element of their risk assessment

    This report identifies those potential energy-conservative pipeline innovations that are most energy- and cost-effective, and formulates recommendations for the R, D, and D programs needed to exploit those opportunities. From a candidate field of over twenty classes of efficiency improvements, eight systems are recommended for pursuit. Most of these possess two highly important attributes: large potential energy savings and broad applicability outside the pipeline industry. The R, D, and D program for each improvement and the recommended immediate next step are described. The eight programs recommended for pursuit are: gas-fired combined-cycle compressor station; internally cooled internal combustion engine; methanol-coal slurry pipeline; methanol-coal slurry-fired and coal-fired engines; indirect-fired coal-burning combined-cycle pump station; fuel-cycle pump station; internal coatings in pipelines; and drag-reducing additives in liquid pipelines.

    The Alberta Chamber of Resources programs and initiatives on oil sands and heavy oil, and strategies for revitalizing oilsands development in Alberta are described. The regional upgrader and satellite production facilities concept, and technology requirements for mineable oil sands by the year 2010 are discussed. Strategic alliances in furtherence of oil sands research and development and the National Task Force on Oil Sands Strategies are described. Changes in requirements for transportation fuels due to stricter regulations and environmental initiatives will cause a trend to lighter fuels with more hydrogen content, less aromatics, nitrogen, sulfur and metals. A preferred refinery configuration will be able to process heavier crudes and synthetic crudes, have no heavy fuel oil product, low sulfur products, low aromatics with high octane, and low operating cost. A regional or central facility that combines the processing capabilities of a bitumen upgrader with the process units of a refinery is preferred. Advantages of this concept are: value addition to the feedstock is maximized; dependence on refineries is eliminated; restriction on synthetic crude oil volumes due to capacity limitations at refineries is eliminated; directly marketable finished products are produced; more stringent quality specifications are satisfied; and the synergies between upgrading and refining improve overall economics of processing. It is recommended that the concept of regional upgraders be adopted for Alberta, strategic alliances be encouraged, incentives for bitumen production be provided, and a bitumen pipeline network be developed. 12 refs

    Daqing oil field is the largest oil field in China. This crude oil is a typical waxy crude oil, with a wax content of 26% and a gel point of 32 deg C. Flow behaviors of waxy crude oils at temperatures near the gel point/pour point are vital for both pipeline hydraulic calculation and evaluation on restartability of a shutdown pipeline. In this study, experimental simulation was conducted by using a stirred vessel with the energy dissipation of viscous flow as the shear simulation parameter. The viscosity, gel point, yield stress and thixotropy were measured by sampling from the simulation vessel. The viscosity under simulated pipelining condition was found less than that measured under quiescent cooling condition. The gel point decreased with decreasing temperature of sampling, i.e. the end temperature of the dynamic cooling process. At sampling temperatures above 35 deg C, that is 3 deg C above the gel point measured under quiescent cooling condition, both the yield stresses and the thixotropic parameters showed little dependence on the shear history. However, at lower sampling temperatures, remarkable shear history dependence was found. Empirical correlations were developed between the yield stress and the sampling temperature as well as the measurement temperature, and between the thixotropic parameters and the sampling temperature.

    This presentation outlined the immense potential of the western Canadian oil sands reserves. Recoverable reserves have been estimated at 180 billion barrels, with production forecasts estimated at 5 million barrels per day by 2030. Resource development is occurring at a time when the world's largest oil importer is increasing supplies through concern for security of supply. The second and third largest oil importers in the world are experiencing economic and energy demand growth. These factors underscore the motivation for rapid growth of the Western Canadian Oil Sands reserves. One of the challenges that must be addressed is to ensure that incremental markets for the increased production are accessed. Another challenge is to ensure adequate infrastructure in terms of pipeline capacity to ensure deliverability of the product. tabs., figs

  10. Economic impacts of oil spills: Spill unit costs for tankers, pipelines, refineries, and offshore facilities

    International Nuclear Information System (INIS)

    1993-01-01

    The impacts of oil spills -- ranging from the large, widely publicized Exxon Valdez tanker incident to smaller pipeline and refinery spills -- have been costly to both the oil industry and the public. For example, the estimated costs to Exxon of the Valdez tanker spill are on the order of $4 billion, including $2.8 billion (in 1993 dollars) for direct cleanup costs and $1.125 billion (in 1992 dollars) for settlement of damages claims caused by the spill. Application of contingent valuation costs and civil lawsuits pending in the State of Alaska could raise these costs appreciably. Even the costs of the much smaller 1991 oil spill at Texaco's refinery near Anacortes, Washington led to costs of $8 to 9 million. As a result, inexpensive waming, response and remediation technologies could lower oil spin costs, helping both the oil industry, the associated marine industries, and the environment. One means for reducing the impact and costs of oil spills is to undertake research and development on key aspects of the oil spill prevention, warming, and response and remediation systems. To target these funds to their best use, it is important to have sound data on the nature and size of spills, their likely occurrence and their unit costs. This information could then allow scarce R ampersand D dollars to be spent on areas and activities having the largest impact. This report is intended to provide the ''unit cost'' portion of this crucial information. The report examines the three key components of the US oil supply system, namely, tankers and barges; pipelines and refineries; and offshore production facilities. The specific purpose of the study was to establish the unit costs of oil spills. By manipulating this key information into a larger matrix that includes the size and frequency of occurrence of oil spills, it will be possible' to estimate the likely future impacts, costs, and sources of oil spills

    Highlights: • Externalities are examined for pipelines, truck, rail, and barge. • Safety impact factors include incidences of injuries, illnesses, and fatalities. • Environmental impact factors include CO_2eq emissions and air pollution disease burden. • Externalities are estimated for constructing and operating a large domestic pipeline. • A large pipeline has lower cumulative impacts than other modes within ten years. - Abstract: The construction of pipelines along high-throughput fuel corridors can alleviate demand for rail, barge, and truck transportation. Pipelines have a very different externality profile than other freight transportation modes due to differences in construction, operation, and maintenance requirements; labor, energy, and material input intensity; location and profile of emissions from operations; and frequency and magnitude of environmental and safety incidents. Therefore, public policy makers have a strong justification to influence the economic viability of pipelines. We use data from prior literature and U.S. government statistics to estimate environmental, public health, and safety characterization factors for pipelines and other modes. In 2008, two pipeline companies proposed the construction of an ethanol pipeline from the Midwest to Northeast United States. This proposed project informs our case study of a 2735-km $3.5 billion pipeline (2009 USD), for which we evaluate potential long-term societal impacts including life-cycle costs, greenhouse gas emissions, employment, injuries, fatalities, and public health impacts. Although it may take decades to break even economically, and would result in lower cumulative employment, such a pipeline would likely have fewer safety incidents, pollution emissions, and health damages than the alternative multimodal system in less than ten years; these results stand even if comparing future cleaner ground transport modes to a pipeline that utilizes electricity produced from coal

    Coburn, L. L.

    1980-12-01

    The undersizing theory hypothesizes that integrated oil companies have a strong economic incentive to size the petroleum pipelines they own and ship over in a way that means that some of the demand must utilize higher cost alternatives. The DOJ theory posits that excess or monopoly profits are earned due to the natural monopoly characteristics of petroleum pipelines and the existence of market power in some pipelines at either the upstream or downstream market. The theory holds that independent petroleum pipelines owned by companies not otherwise affiliated with the petroleum industry (independent pipelines) do not have these incentives and all the efficiencies of pipeline transportation are passed to the ultimate consumer. Integrated oil companies on the other hand, keep these cost efficiencies for themselves in the form of excess profits.

    The construction of the Baku-Tbilisi-Ceyhan (BTC) oil and South Caucasus gas (SCP) pipelines was completed in 2005 and 2006, respectively. The Azerbaijan section of the BTC oil and SCP gas pipelines is 442 km long and lies in a 44 m wide corridor named as the Right-of-Way (RoW). BTC and SCP pipelines are aligned parallel to each other within the RoW. The construction process significantly disturbed vegetation and soil cover along the RoW of the pipelines. The revegetation and erosion control measures were conducted after the completion of construction to restore disturbed footprints of construction. The general goals of the present studies, dedicated to the environmental monitoring and erosion control measures were to evaluate the status of the revegetation in 2007 since the completion of the construction activities and to determine erosion-prone areas along the RoW. Quantitative assessment of vegetation cover (VC) was based on the regression and RMSE analysis using IKONOS NDVI 2007 and in-situ estimation of VC percentage for the normalization of NDVI to VC. The prediction of erosion-prone areas was based on the Universal Soil Loss Equation (USLE). The prediction reliability of USLE was evaluated using in-situ collected erosion occurrences. (orig.)

    In order to determine the feasibility of pipeline as an intercity freight transportation mode, it was necessary to examine its technological feasibility and reliability. This report describes the technology of the major generic freight pipelines in terms of both historical and current trends and operations. Additionally, it presents a state-of-the-art review of calculating energy requirements of various generic freight pipelines. It was concluded that slurry and pneumatic pipelines are technologically feasible and reliable. There are many commercial installations of both types operating around the world. Based on European experience with pneumo-capsule pipelines for mail delivery and Russian gravel- and sand-transport installations, it appears that a pneumo-capsule pipeline is a technologically feasible and operationally reliable mode for transport of solids. Since no commercial pneumo-capsule pipeline installations yet exist in the U.S., it seems desirable that a service demonstration of the advantages and feasibility of this mode of transport be undertaken to attract the shippers' confidence. Hydro-capsule pipelines are technologically feasible, but its reliability within a commercial environment remains to be tested.

    Pipelines are naturally vulnerable to operational, environmental and man-made effects such as internal erosion and corrosion; mechanical deformation due to geophysical risks and ground movements; leaks from neglect and vandalism; as well as encroachments from nearby excavations or illegal intrusions. The actual detection and localization of incipient and advanced faults in pipelines is a very difficult, expensive and inexact task. Anything that operators can do to mitigate the effects of these faults will provide increased reliability, reduced downtime and maintenance costs, as well as increased revenues. This talk will review the on-line monitoring of an extensive network of oil pipelines in service in Colombia using optical fiber Bragg grating (FBG) strain sensors for the measurement of strains and bending caused by geohazard risks such as soil movements, landslides, settlements, flooding and seismic activity. The FBG sensors were mounted on the outside of the pipelines at discrete locations where geohazard risk was expected. The system has been in service for the past 3 years with over 1,000 strain sensors mounted. The technique has been reliable and effective in giving advanced warning of accumulated pipeline strains as well as possible ruptures.

    In response to public concerns regarding the safe operation of pipelines, operators are relying on risk management to balance the demands of pipeline integrity and service competitiveness. This paper presented a procedure for calculating the probability of failure according to the API 581 BRD RB I methodology that uses data collected from 3 existing oil pipelines subject to internal corrosion. The risk exposure that the pipeline may be subjected to during its remaining operating life was evaluated. Risk is a function of the probability of failure and the consequences of that failure. Therefore, if the consequences of the failure are assumed to remain unchanged for a given equipment under specific operational conditions, then risk reduction will only be achieved by decreasing the probability of failure and through management of the inspection process. It was shown that if the confidence on the damage rate and on the inspection effectiveness is known, then it is possible to design an alternative to an existing inspection plan. This calls for pig inspections at 5 year intervals to ensure that the probability of failures for pipelines will be under a certain level of tolerable risk. 9 refs., 4 tabs., 3 figs.

    Highlights: • Comprehensive analysis of the efficiency and safety strategies of transport CO 2 . • Selection of safety zones around pipelines transporting CO 2 . • Optimization of CO 2 pipeline transportation conditions. - Abstract: The aim of this paper is to analyze CO 2 compression and transportation processes with safety issues for post-combustion CO 2 capture applications for basic technological concepts of a 900 MW pulverized coal-fired power plant. Four various types of compressors including a conventional multistage centrifugal compressor, an integrally geared centrifugal compressor, a supersonic shock wave compressor, and pump machines were used. This study emphasizes that total compression power is a strong function of the thermodynamic process and is not only determined by the compressor efficiency. The compressor increases the CO 2 pressure from normal pressure to critical pressure and the boosting pump continues to increase the pressure to the required pressure for the pipeline inlet. Another problem analyzed in this study is the transport of CO 2 by pipeline from the compressor outlet site to the disposal site under heat transfer conditions. Simulations were made to determine maximum safe pipeline distance to subsequent booster stations depending on inlet pressure, environmental temperature, the thermal insulation thickness and the ground level heat transfer conditions. From the point of view of environmental protection, the most important problem is to identify the hazards which indirectly affect CO 2 transportation in a strict and reliable manner. This identification is essential for effective hazard management. A failure of pipelines is usually caused by corrosion, material defects, ground movement or third party interference. After the rupture of the pipeline transporting liquid CO 2 , a large pressure drop will occur. The pressure will continue to fall until the liquid becomes a mixture of saturated vapour/liquid.

    North Slope oil and gas resources are a critical part of US energy supplies and their development is facing a period of new growth to meet increasing national energy needs. While this growth is taking place in areas active in development for more than 20 years, there are many increasing environmental challenges facing industry and management agencies. A majority of all exploration and development activities, pipeline maintenance and other field support activities take place in the middle of winter, when the fragile tundra surface is more stable. The window for the critical oil and gas winter operational season has been steadily decreasing over the last 25 years. The number of companies working on the North Slope is increasing. Many of these companies are smaller and working with fewer resources than the current major companies. The winter operations season starts with the tundra-travel opening, which requires 15 cm of snow on the land surface in the coastal management areas and 23 cm in the foothills management areas. All state managed areas require -5°C soil temperatures at a soil depth of 30 cm. Currently there are no methods to forecast this opening date, so field mobilization efforts are dependent on agency personnel visiting field sites to measure snow and soil temperature conditions. Weeks can be easily lost in the winter operating season due to delays in field verification of tundra conditions and the resulting mobilization. After the season is open, a significant percentage of exploration, construction, and maintenance do not proceed until ice roads and pads can be built. This effort is dependent on access to lake ice and under-ice water. Ice chipping is a common ice-road construction technique used to build faster and stronger ice roads. Seasonal variability in water availability and permitting approaches are a constant constraint to industry. At the end of the winter season, projects reliant on ice-road networks are often faced with ending operations

    2014-11-01

    Full Text Available This paper describes the transient dynamics behavior of oil flow in a pipe with the presence of one or two leaks through fluid dynamics simulations using the Ansys CFX commercial software. The pipe section is three-dimensional with a pipe length of 10 m, a pipe diameter of 20 cm, and leak diameter of 1.6 mm. The interest of this work is to evaluate the influence of the flow velocity, and the number and position of leaks on the transient pressure behavior. These new data may provide support for more efficient detection systems. Thus, this work intends to contribute to the development of tools of operations in oil and gas industry.

  1. Pollution from pipelines

    International Nuclear Information System (INIS)

    1991-01-01

    During the 1980s, over 3,900 spills from land-based pipelines released nearly 20 million gallons of oil into U.S. waters-almost twice as much as was released by the March 1989 Exxon Valdez oil spill. Although the Department of Transportation is responsible for preventing water pollution from petroleum pipelines, GAO found that it has not established a program to prevent such pollution. DOT has instead delegated this responsibility to the Coast Guard, which has a program to stop water pollution from ships, but not from pipelines. This paper reports that, in the absence of any federal program to prevent water pollution from pipelines, both the Coast Guard and the Environmental Protection Agency have taken steps to plan for and respond to oil spills, including those from pipelines, as required by the Clean Water Act. The Coast Guard cannot, however, adequately plan for or ensure a timely response to pipeline spills because it generally is unaware of specific locations and operators of pipelines

  2. Transnational opposition and negotiation: Challenges to an oil pipeline in Ecuador

    Science.gov (United States)

    Widener, Patricia

    The literature on transnational networks portrays transnational collaborations as advantageous to domestic stakeholders. Yet, the gains of transnational engagement may be accompanied by hardship for domestic groups. This dissertation examines how domestic stakeholders experienced the benefits and burdens of transnational collaboration in challenging the construction of the oil pipeline, the Oleoducto de Crudos Pesados, in Ecuador. Four community cases along the pipeline's route were selected for analysis. Each case varied by the experienced externalities of the oil industry and distributive struggle with the industry and the state. Lago Agrio, an oil town on the edge of the Amazon, represented a community with 30 years of oil saturation that engaged the state to determine just compensation. The capital Quito represented the nation's environmental organizations that sought a role in directing oil-funded conservation efforts. The third site, the eco-tourism community of Mindo, mobilized to reject the pipeline's route near their private reserves and to promote eco-tourism as an economic alternative to oil extraction. The final site was Esmeraldas, a coastal community experienced in tanker loading and oil refining that achieved a collective dignity in pressing for community-determined compensation. To better understand the impacts of transnational activities, this dissertation synthesizes theories of social movements, environmental justice and development. In its longitudinal and case study design, the examination of one project at four sites of contention offers insight into how transnational mobilization drives or hinders environmental justice and how grassroots groups gain or lose a forum for participation. My findings indicate that transnational campaigns benefited locals by providing expert assessments, facilitating international access and influencing international financing policies. However, the unintended consequences included a focus on international concerns

    Full text : Baku-Tbilisi-Ceyhan (BTC) oil pipeline covers the area of 6 districts of the Western region of Azerbaijan. This area mainly consists of fertile agricultural lands and rich in rivers and valuable Tugay forests around Kura river. Each small breakdown that can take place during oil transportation can be a reason of irreversible ecological calamity in this region. For avoiding transformation of breakdown into calamity and timely liquidation of damage to environment during the pipeline exploitation an increase of public activeness in the communities along the pipeline is one of the main factors in bio-diversity protection. Eco-Renaissance Organization took part in the monitoring of BTC oil pipeline on the project of Open Society Institute - Assistance Foundation and conducted a social survey concerning environment at the areas crossed by the pipeline. Analyzed the results of the survey it became clear that one of the main problems worrying the population is a restoration of disturbed bio-diversity. During the survey conducting it was also found out that there is a pre-condition for increase of public activeness in the communities living along the pipeline. Taking into account that the majority of the Organization's members are employees of Sustainable Development and Ecological Monitoring Laboratory of Ganja Regional Scientific Center of Azerbaijan National Academy of Sciences, we see that increase of activeness of the public in environment protection at the areas crossed by the pipeline also meets our professional interests. The public's assistance is a very important factor for creation of ecological monitoring of the region. We think that it's necessary. To define active citizen in the communities; To organize training of these people and through it creation of strongpoints at the areas along the pipeline can be reached. With the purpose of detailed analysis of environment situation at these areas a committee consisting of inhabitants of the communities

    Subsea oil well blowouts and pipeline leaks release oil and gas to the environment through vigorous jets. Predicting the breakup of the released fluids in oil droplets and gas bubbles is critical to predict the fate of petroleum compounds in the marine water column. To predict the gas bubble size in oil well blowouts and pipeline leaks, we observed and quantified the flow behavior and breakup process of gas for a wide range of orifice diameters and flow rates. Flow behavior at the orifice transitions from pulsing flow to continuous discharge as the jet crosses the sonic point. Breakup dynamics transition from laminar to turbulent at a critical value of the Weber number. Very strong pure gas jets and most gas/liquid co-flowing jets exhibit atomization breakup. Bubble sizes in the atomization regime scale with the jet-to-plume transition length scale and follow -3/5 power-law scaling for a mixture Weber number. Copyright © 2018 Elsevier Ltd.

    A large scale risk assessment was performed by Det Norske Veritas (DNV) for the entire Kuwait Oil Company (KOC) pipeline network. This risk assessment was unique in that it incorporated the assessment of all major sources of process related risk faced by KOC and included root cause management system related risks in addition to technical risks related to more immediate causes. The assessment was conducted across the entire pipeline network with the scope divided into three major categories:1. Integrity Management 2. Operations 3. Management Systems Aspects of integrity management were ranked and prioritized using a custom algorithm based on critical data sets. A detailed quantitative risk assessment was then used to further evaluate those issues deemed unacceptable, and finally a cost benefit analysis approach was used to compare and select improvement options. The operations assessment involved computer modeling of the entire pipeline network to assess for bottlenecks, surge and erosion analysis, and to identify opportunities within the network that could potentially lead to increased production. The management system assessment was performed by conducting a gap analysis on the existing system and by prioritizing those improvement actions that best aligned with KOC's strategic goals for pipelines. Using a broad and three-pronged approach to their overall risk assessment, KOC achieved a thorough, root cause analysis-based understanding of risks to their system as well as a detailed list of recommended remediation measures that were merged into a 5-year improvement plan.

    The execution of the OSBAT 24{sup o}il pipeline rehabilitation project, comprising the substitution of a 30 km section of the 37 years old pipeline has become a real benchmark in the history of this kind of job. The pipeline is inserted in one of the most sensitive environmental areas of the Sao Paulo State - the last Environmental Protection Area of the Mata Atlantica . The growth of human presence in its surroundings during the last three decades, has caused the right-of-way to be totally confined by luxury housing developments, streets, highways and resorts, as well as by the local communities and their activities, schools, and commerce. The pipeline runs through the Serra do Mar unstable mountain range slopes, with sequences of very steep hills and ravines followed by swamps and rivers. The success of such a challenging project - assembling the new line in a narrow ROW with all its restrictions, where the old line was still in operation, and complying with the tight work schedule required by PETROBRAS, was only possible due to a carefully managed combination of: accurate planning, best engineering methods and equipment and experienced workforce, deeply integrated in a massive effort towards safety, environmental care and social responsibility.

    1996-01-01

    Sites in northern Alberta, in which oil spills occurred more than 23 years ago, were revisited. The Nipisi spill occurred when a rupture in the underground oil pipeline leaked 60,000 barrels of crude into a 25 acre bog, with very little drainage. It was one of the largest spills in Canadian history. The Rainbow spill was into a fen that was draining by subsurface seepage. Treatments at the time included burning, tilling, and fertilizer addition. The sites were revisited in order to take samples and to evaluate both the natural and enhanced recovery and the effectiveness of the cleanup techniques. The long-term persistence of oil residues and changes in oil character resulting from weathering and biodegradation over time, were studied. Results showed that samples of oil residue and vegetation were still highly contaminated with oil which was heavily degraded. Subsurface samples were contaminated but the oil was only slightly degraded. The Nipisi site still had large areas devoid of vegetation. The unique drainage of peat bogs and the influence it has on rehabilitation was described. It was concluded that although the sites are recovering, they are doing so at a very slow pace and will require some more time to be complete. 12 refs., 4 tabs., 9 figs

    Business process modeling (BPM) using event driven process chain diagrams (EPCs) to lay out business process work flows is now widely adopted around the world. The EPC method was developed within the framework of the ARIS Toolset developed by Prof. Wilhelm-August Scheer at the Institut fur Wirtschaftsinformatik at the Universitat des Saarlandes, in the early 1990s. It is used by many companies to model, analyze and redesign business processes. As such it forms the core technique for modeling in ARIS, which serves to link the different aspects of the so-called control view, which is discussed in the section on ARIS business process modeling. This paper describes a proposal made to TRANSPETRO's Oil Pipelines and Terminals Division in the states of Rio de Janeiro and Minas Gerais, which will be jointly developed by specialists and managers from TRANSPETRO and from COPPETEC, the collaborative research arm of Rio de Janeiro Federal University (UFRJ). The proposal is based on ARIS business process modeling and is presented here according to its seven phases, as follows: information survey and definition of the project structure; mapping and analysis of Campos Eliseos Terminal (TECAM) processes; validation of TECAM process maps; mapping and analysis of the remaining organizational units' processes; validation of the remaining organizational units' process maps; proposal of a business process model for all organizational units of TRANSPETRO's Oil Pipelines and Terminals Division in Rio de Janeiro and Minas Gerais; critical analysis of the process itself and the results and potential benefits of BPM.

    The oil export pipelines of Marlim Sul field Module 3, Campus Basin, offshore Brazil, will operate in high pressure and temperature conditions, and will be laid on seabed crossing ten previously laid pipelines along the routes. In terms of thermo-mechanical design, these conditions turn out to be great challenges. In order to obtain initial results and recommendations for detail design, a preliminary thermo-mechanical design of pipelines was carried out as a fast-track design before the bid. This way, PETROBRAS can assess and emphasize the susceptibility of these lines to lateral buckling and pipeline walking behavior. Therefore, PETROBRAS can present a preliminary mitigation strategy for lateral buckling showing solutions based on displacement controlled criteria and by introducing buckle initiation along the pipeline using distribution buoyancy. Besides that, axial displacements and loads at the pipeline ends can be furnished also in order to provide a basis for the detailed design. The work reported in this paper follows the SAFEBUCK JIP methodology and recommendation, which were used to determine the allowable strain and maximum allowable VAS (Virtual Anchor Spacing) considered in the buckling mitigation strategy. The paper presents also the formation of uncontrolled buckles on the seabed and the propensity for pipeline walking in its sections between buckles. The buckling mitigation strategy established in this preliminary design confirms that the oil pipeline specifications are adequate to maintain integrity during design life. (author)

High molecular weight polymers are used to reduce the frictional pressure loss ratio in crude oil pipelines, refined fuel and aqueous pipelines. Chemical structure of the main used pipeline drag reducers is one of the following polymers and copolymers classified according to the type of fluid to ; low density polyethylene, copolymer of I-hexane cross linked with divinyl benzene, polyacrylamide, polyalkylene oxide polymers and their copolymers, fluorocarbons, polyalkyl methacrylates and terpolymer of styrene, alkyl acrylate and acrylic acid. Drag reduction is the increase in pump ability of a fluid caused by the addition of small amounts of an additive to the fluid. The effectiveness of a drag reducer is normally expressed in terms of percent drag reduction. Frictional pressure loss in a pipeline system is a waste of energy and it costly. The drag reducing additive minimizes the flow turbulence, increases throughput and reduces the energy costs. The Flow can be increased by more than 80 % with existing assets. The effectiveness of the injected drag reducer in Mostorod to Tanta crude oil pipeline achieved 35.4 % drag reduction and 23.2 % flow increase of the actual performance The experimental application of DRA on Arab Petroleum Pipeline Company (Summed) achieved a flow increase ranging from 9-32 %

    The objective of this study consisted in investigating the possible causes which give rise to the presence of low wall pipe thicknesses on a 16'' natural gas transport pipeline, even though during the last 12-year period cathodic protection (CP) potentials were kept in the protection range at which external corrosion should not occur. Results from in-line inspection from a 16'' natural gas transport pipeline showed 46 indications with more than 80% wall thickness lost due to external corrosion in the second segment of the pipeline. Direct inspection at the indication locations, review of the CP system performance, pipeline maintenance programs and studies, allowed to make an integral diagnostic where it was found out that the main cause of external corrosion was an inappropriate coating application since the pipeline construction, this situation has originated the increase of CP shielding effects through time.

    Highlights: • The influence of stochastic properties and conditions on permafrost foundation was investigated. • A stochastic analysis for the uncertain thermal characteristic of crude oil pipe is presented. • The mean temperature and standard deviation of foundation soils are obtained and analyzed. • Average standard deviation and maximum standard deviation of foundation soils increase with time. - Abstract: For foundation soils surrounding the crude oil pipeline in permafrost regions, the soil properties and the upper boundary conditions are stochastic because of complex geological processes and changeable atmospheric environment. The conventional finite element analysis of thermal characteristics for crude oil pipeline is always deterministic, rather than taking stochastic parameters and conditions into account. This study investigated the stochastic influence of an underground crude oil pipeline on the thermal stability of the permafrost foundation on the basis of a stochastic analysis model and the stochastic finite element method. A stochastic finite element program is compiled by Matrix Laboratory (MATLAB) software, and the random temperature fields of foundation soils surrounding a crude oil pipeline in a permafrost region are obtained and analyzed by Neumann stochastic finite element method (NSFEM). The results provide a new way to predict the thermal effects of the crude oil pipeline in permafrost regions, and it shows that the standard deviations in temperature increase with time when considering the stochastic effect of soil properties and boundary conditions, which imply that the results of conventional deterministic analysis may be far from the true value, even if in different seasons. It can improve our understanding of the random temperature field of foundation soils surrounding the crude oil pipeline and provide a theoretical basis for actual engineering design in permafrost regions.

    The authors discuss the history and importance of the East-Siberia-Pacific Oil Pipeline (ESPO). This new pipeline is a crucial element of Russia's energy strategy, which calls for the diversification of Russian energy exports by developing East Siberia's oil and gas resources. The authors recall how the Russian state lost its grip on the economy in the 1990s when oligarchs, such as Michail Khodorkovsky, were able to take control over the oil sector, in particular East Siberia's resources. Khodorkovsky bypassed the Moscow government and proposed building a pipeline to China. His plans were only focused on his company's interests, while the Russian state would only get a small share of the revenues. The re-emerging Russian state under president Putin brought a halt to this project and opted for a route that would give Russia the opportunity to export oil to Japan. The struggle for this pipeline and its final route provides an interesting case study of recent political changes in Russia. Furthermore, it illustrates how the Russian state has re-asserted control over the energy industry and which role energy plays in the country's foreign economic policy. Siberia's energy resources can help Russia to participate in the economic rise of the Asia-Pacific region. ESPO is a first step to realize Siberia's potential and to boost Russia's political and economic position in East Asia and beyond. Hence the pipeline is a clear signal of Russia's re-emergence as a powerful player on the Eurasian continent. [Dutch] De auteurs bespreken de geschiedenis en het belang van de Oost-Siberie - Pacific Oil Pipeline (ESPO). Deze nieuwe pijpleiding is een cruciaal onderdeel in de Russische energie-strategie, waarin wordt opgeroepen tot de diversificatie van de Russische energie-export door het ontwikkelen van Oost-Siberische olie- en gasbronnen. De auteurs herinneren eraan hoe de Russische staat zijn greep verloor op de economie in de jaren 1990

  7. Intrusion detection on oil pipeline right of way using monogenic signal representation

    We present an object detection algorithm to automatically detect and identify possible intrusions such as construction vehicles and equipment on the regions designated as the pipeline right-of-way (ROW) from high resolution aerial imagery. The pipeline industry has buried millions of miles of oil pipelines throughout the country and these regions are under constant threat of unauthorized construction activities. We propose a multi-stage framework which uses a pyramidal template matching scheme in the local phase domain by taking a single high resolution training image to classify a construction vehicle. The proposed detection algorithm makes use of the monogenic signal representation to extract the local phase information. Computing the monogenic signal from a two dimensional object region enables us to separate out the local phase information (structural details) from the local energy (contrast) thereby achieving illumination invariance. The first stage involves the local phase based template matching using only a single high resolution training image in a local region at multiple scales. Then, using the local phase histogram matching, the orientation of the detected region is determined and a voting scheme gives a certain weightage to the resulting clusters. The final stage involves the selection of clusters based on the number of votes attained and using the histogram of oriented phase feature descriptor, the object is located at the correct orientation and scale. The algorithm is successfully tested on four different datasets containing imagery with varying image resolution and object orientation.

    A light crude oil spill occurred along a section of pipeline near the bank of a major river of a southern Alberta community in December of 1995. Crude oil was observed at ground surface over an area of 2,000 sq m at the top of the river slope. It had also migrated down slope through the subgrade soils and along the groundwater table toward the river. The initial emergency response measures included removing and disposing of oil-stained vegetation and snow, and the containment and recovery of free oil pooled on the ground surface. Other measures included the drilling of test holes and boreholes and the installation of groundwater monitoring and recovery wells. It was determined that phase-separated crude oil had accumulated at the water table within the flood plain sediments near the river. The water was remediated on-site to Canadian drinking water quality standards. The zone of impacted water was effectively captured, and ground water quality steadily improved

    PETROBRAS has been using THPS biocide since 2000 to control sulphate reducing bacteria (SRB) and H{sub 2}S generation in FPSO's tanks, storage tanks, seawater injection systems, produced water systems and hydrostatic testings. The advantage of this product over other biocides is to be effective against sessile SRB and to have low environmental impact and low risk to operators' health. Since 2005 the use of THPS was also extended to oil pipelines and has being demonstrating high efficacy in controlling sessile SRB and sulfide formation, even in fluids with very low water cut (BSW < 1%). However, some deleterious effects were observed when THPS (formulated with 75% of active ingredient) was dosed continuously in the produced fluids, in high concentration and/or for long periods. This paper presents the results of THPS treatment in two PETROBRAS' oil pipelines and describes the side effects that were detected during the biocide injection. The actions taken to minimize these harmful effects, without losing the good biocide efficiency were also presented. (author)

  14. Entropy Production in Pipeline Flow of Dispersions of Water in Oil

    2014-08-01

    Full Text Available Entropy production in pipeline adiabatic flow of water-in-oil emulsions is investigated experimentally in three different diameter pipes. The dispersed-phase (water droplets concentration of emulsion is varied from 0 to 41% vol. The entropy production rates in emulsion flow are compared with the values expected in single-phase flow of Newtonian fluids with the same properties (viscosity and density. While in the laminar regime the entropy production rates in emulsion flow can be described adequately by the single-phase Newtonian equations, a significant deviation from single-phase flow behavior is observed in the turbulent regime. In the turbulent regime, the entropy production rates in emulsion flow are found to be substantially smaller than those expected on the basis of single-phase equations. For example, the entropy production rate in water-in-oil emulsion flow at a dispersed-phase volume fraction of 0.41 is only 38.4% of that observed in flow of a single-phase Newtonian fluid with the same viscosity and density, when comparison is made at a Reynolds number of 4000. Thus emulsion flow in pipelines is more efficient thermodynamically than single-phase Newtonian flow.

    Safety operation, condition monitoring, periodical inspection and rehabilitation of high-pressure hydro-carbon transporting pipelines are a complex problem. To answer arising questions is inconceivable without technical-critical evaluation of defects - originated during manufacturing or operation - can be found on the pipeline. This evaluation must be in line with requirements of our age, i.e. it has to assert such concept of which basis is not the `possible worst` but the `just happening wrong`. Solving these problems without application of computer resources is inconceivable in our time. The final purpose of the solution is the expert system and among the components of the expert system primarily the development of the knowledge base is needed. The paper demonstrates a possible structure of the knowledge base, furthermore its fundamental elements and their contents (defect types, evaluation possibilities of defects, categorisation of pipelines) and summaries the prospective advantages of its application.

    It is impractical to transport bitumen and heavy oil by pipelines at ambient temperature unless diluents are added to reduce the viscosity. A diluted bitumen pipeline is commonly referred to as a dilbit pipeline. The diluent routinely used is natural gas condensate. Since natural gas condensate is limited in supply, it must be recovered and reused at high cost. This paper presented an alternative to the use of diluent to reduce the viscosity of heavy oil or bitumen. The following two basic design issues for a hot bitumen (hotbit) pipeline were presented: (1) modelling the restart problem, and, (2) establishing the maximum practical operating temperature. The transient behaviour during restart of a high temperature pipeline carrying viscous fluids was modelled using the concept of flow capacity. Although the design conditions were hypothetical, they could be encountered in the Athabasca oilsands. It was shown that environmental disturbances occur when the fluid is cooled during shut down because the ground temperature near the pipeline rises. This can change growing conditions, even near deeply buried insulated pipelines. Axial thermal loads also constrain the design and operation of a buried pipeline as higher operating temperatures are considered. As such, strain based design provides the opportunity to design for higher operating temperature than allowable stress based design methods. Expansion loops can partially relieve the thermal stress at a given temperature. As the design temperature increase, there is a point at which above grade pipelines become attractive options, although the materials and welding procedures must be suitable for low temperature service. 3 refs., 1 tab., 10 figs.

  18. Use of Short Chained Alkylphenols (SCAP in Analysis of Transport Behaviour of Oil Contaminated Groundwater

    Directory of Open Access Journals (Sweden)

    M. Sauter

    2002-06-01

    Full Text Available Shortchained alkylphenols (SCAP represent a main constituent of crude oil and coal liquefaction products. Due to their specific oil/water partitioning behaviour and high aqueous solubility they can be detected in oil exploitation waters and groundwaters affected by various spills near oil pipelines, oil exploitation sites and coal liquefaction plants. New efficient and powerful analytical techniques have been developed that allow the identification of all 34 individual compounds (C0-C3 without derivatisation and in complex matrices. Due to the different physico-chemical properties of the SCAP, differential transport behaviour in groundwater can be observed, changing the relative concentrations of SCAP downgradient in space and time. These characteristic ratios can be employed to derive information on migration direction and the ageing of the source of contamination. A case study is presented to illustrate the use of this new tool.

    2017-11-01

    The aim of this study was to identify an optimal CCS transport infrastructure for Polish energy sector in regards of selected European Commission Energy Roadmap 2050 scenario. The work covers identification of the offshore storage site location, CO2 pipeline network design and sizing for deployment at a national scale along with CAPEX analysis. It was conducted for the worst-case scenario, wherein the power plants operate under full-load conditions. The input data for the evaluation of CO2 flow rates (flue gas composition) were taken from the selected cogeneration plant with the maximum electric capacity of 620 MW and the results were extrapolated from these data given the power outputs of the remaining units. A graph search algorithm was employed to estimate pipeline infrastructure costs to transport 95 MT of CO2 annually, which amount to about 612.6 M€. Additional pipeline infrastructure costs will have to be incurred after 9 years of operation of the system due to limited storage site capacity. The results show that CAPEX estimates for CO2 pipeline infrastructure cannot be relied on natural gas infrastructure data, since both systems exhibit differences in pipe wall thickness that affects material cost.

  20. Development of the Write Process for Pipeline-Ready Heavy Oil

    Work completed under this program advances the goal of demonstrating Western Research Institute's (WRI's) WRITE{trademark} process for upgrading heavy oil at field scale. MEG Energy Corporation (MEG) located in Calgary, Alberta, Canada supported efforts at WRI to develop the WRITE{trademark} process as an oil sands, field-upgrading technology through this Task 51 Jointly Sponsored Research project. The project consisted of 6 tasks: (1) optimization of the distillate recovery unit (DRU), (2) demonstration and design of a continuous coker, (3) conceptual design and cost estimate for a commercial facility, (4) design of a WRITE{trademark} pilot plant, (5) hydrotreating studies, and (6) establish a petroleum analysis laboratory. WRITE{trademark} is a heavy oil and bitumen upgrading process that produces residuum-free, pipeline ready oil from heavy material with undiluted density and viscosity that exceed prevailing pipeline specifications. WRITE{trademark} uses two processing stages to achieve low and high temperature conversion of heavy oil or bitumen. The first stage DRU operates at mild thermal cracking conditions, yielding a light overhead product and a heavy residuum or bottoms material. These bottoms flow to the second stage continuous coker that operates at severe pyrolysis conditions, yielding light pyrolyzate and coke. The combined pyrolyzate and mildly cracked overhead streams form WRITE{trademark}'s synthetic crude oil (SCO) production. The main objectives of this project were to (1) complete testing and analysis at bench scale with the DRU and continuous coker reactors and provide results to MEG for process evaluation and scale-up determinations and (2) complete a technical and economic assessment of WRITE{trademark} technology to determine its viability. The DRU test program was completed and a processing envelope developed. These results were used for process assessment and for scaleup. Tests in the continuous coker were intended to

    Visual operations management (VOM) takes advantage of visual cues to communicate information, simplify processes and improve the quality and safety of operations. Because of heightened competition, the importance of standardization and quality management processes has become more evident for pipeline companies. Petrobras Transporte's marine terminal units has been working over the last years to be recognized as a reference in the activities it pursues. This is based on the Petrobras Transporte's strategic plan 2020, which foresees amongst others, the specialization of technical workforce, operational safety excellence, capital discipline, customer satisfaction, the search for new technologies and markets and the rendering of new services. To achieve these goals, the Marine Terminals standardization program must be adhered to. Focusing on communication and adoption of standards and procedures, this paper describes how visual guides were conceived and implemented within Petrobras Transporte to enable operators and technicians to meet operational, environmental and occupational health and safety requirements.

    This paper intends to give a brief overview of some cost reduction alternatives in oil pipelines, to optimize the pipeline operation. Four different alternatives are presented, based on previous studies made on existing pipelines, to demonstrate the response obtained with these solutions. Pipeline operation, especially on mature ones, tends to have a high operational cost, be by tradition, the aging of the installation, change of operational characteristics - such as nominal flow, product, or even flow direction - for which the pipeline wasn't originally designed. The alternatives showed allow for an increase survival time of the pipeline, without resorting to major changes, such as replacement of pipes or adding pumping stations to the system. The alternative studied varies from no implementation cost to high installation cost or operational cost increase, depending on the system and the alternative chosen. From changing the pump arrays during operation or changing the products viscosity with different blends, that represent virtually no cost to the pipeline operation, to the use of VFDs, with a high installation cost or DRA, which increase the operational cost.

    In 2002 we changed 13 valves on deck of one gas production platform called Nohoch-A-Enlace at Cantarell Offshore Oil Field. The 20'' diameter gas pipeline and 200 km of length, transport and deliver gas for others production platforms in the Gas Lift System, So 2 millions of oil barrels per day depends of the operation of this gas pipeline but there was 13 valves on pig traps to be changed after 20 years of service to high pressure (64 to 63 kg/cm{sup 2}). We could not stop the operation of this pipeline and some little gas leaks were eliminated in some parts of the valves. This pipeline has two risers so the gas can be injected by two sides of the ring of 20 Km. So we found the proper technology in order to isolate one riser nad change 8 valves and the isolate the other and change the 5, and the gas lift system never stop during the plug and maintenance operations on platform. In the first isolation plug operation this tool run 20 mts inside the riser and was actionated and resists 65 Kg/cm{sup 2} of gas pressure during 44 hours so we changed 8 valves: 2 of 20'', 2 of 10'', 3 of 4'' and 1 of 8'' diameter. In the second isolation the plug run 30 mts inside the second risers and resist 64 Kg/cm{sup 2} of gas during 46 hours and we changed 5 valves of 20'' diameter. In the paper I will describe all the details of this successful operations and procedures. Also the aspects of Health, Security and Environment that we prepared one year before this operations at platform. Pemex save almost 2.5 millions of dollars because the gas lift system never stop and all valves were changed and now we can run cleaning and inspection tools inside the full ring. We used the first isolation plug in Latin America and we want to share this experience to all the pipeline operators in the world as a good practice in pipeline maintenance using plugging technology in the main and large pipelines of high pressure.

    As a response to the Russian dominance of the EU's natural gas supplies and the EU's increasing gas demands, major gas pipeline projects are currently under way to enhance the EU's energy supply security. Oftentimes to raise financing and to allocate gas transportation capacities, auctions are carried out to allow gas shippers to book transportation rights. In recent years, auctions have emerged as one of the most successful allocation mechanisms in the microeconomic theory. However, different auction designs can lead to different outcomes making the choice of auction design a decisive one, especially for divisible-good auctions. This paper seeks to give a formulation of an optimal auction design for gas pipeline transportation capacity. Specifically three different mechanisms are tested: (i) NPV allocation; (ii) pro rata allocation; and (iii) optimization. In addition, Nabucco is taken as a case study to empirically show results of such auction designs. Results show that a trade-off between revenue optimization and fair allocation can be observed: allocation per optimization is the favorable auction design when revenue maximization is more important than fair allocation. On the other hand, pro rata allocation is the auction design to be chosen when fairness of allocation is considered most central. - Research highlights: → Auction design for gas pipeline transportation capacity. → Empirical market-survey of Nabucco pipeline project auction as input data. → Testing of three different allocation mechanisms: (i) NPV allocation; (ii) pro rata allocation; and (iii) optimization. → Results show a trade-off between revenue optimization and fair allocation. → Allocation per optimization is the favorable auction design when revenue maximization is more important than fair allocation. → On the other hand, pro rata allocation is the auction design to be chosen when fairness of allocation is considered most central.

    The implementation of an Integrity Management Program (IMP) in a crude oil pipeline system is focused on the accomplishment of two primary corporative objectives: to increase safety operation margins and to optimize available resources. A proactive work philosophy ensures the safe and reliable operation of the pipeline in accordance with current legislation. The Integrity Management Program is accomplished by means of an interdisciplinary team that defines the strategic objectives that complement and are compatible with the corporative strategic business plan. The implementation of the program is based on the analysis of the risks due to external corrosion, third party damage, design and operations, and the definition of appropriate mitigation, inspection and monitoring actions, which will ensure long-term integrity of the assets. By means of a statistical propagation model of the external defects, reported by high-resolution magnetic inspection tool (MFL), together with the information provided by corrosion sensors, field repair interventions, close internal surveys and operation data, projected defect depth; remaining strength and failure probability distributions were obtained. From the analysis, feasible courses of action were established, including the inspection and repair plan, the internal inspection program and both corrosion monitoring and mitigation programs.

    Full Text Available THE INVISIBLE COST OF PIPELINE CONSTRAINTS Over much of the last decade pipeline constraints and the resulting apportionment of pipeline capacity have meant reduced returns on Alberta’s Oil Exports. There is a natural price discount between the US benchmark West Texas Intermediate (WTI Crude oil price and the Canadian benchmark Western Canada Select (WCS price. This differential reflects the lower quality of WCS relative to WTI and the costs associated with pipeline tolls to transport this oil from Alberta to US refining hubs. However, at present western Canada is experiencing significant pipeline capacity constraints which have dramatically increased this discount relative to historical levels.

    Full text : All way of hydrocarbonic raw material from a mouth of oil wells up to the consumer is accompanied by losses which occur as a result of evaporation, outflow and change of quality. Therefore preservation of quantity and quality of oil and mineral oil during transportation and storages is the major not only economic, but also an ecological problem. The facilitated fractional structure, the big maintenance concern to prominent features of the majority oil from underground salts adjournment Prycaspi in them of the easy hydrocarbons, the raised gas factor in conditions of deposits and presence in structure of gases, except for hydrocarbons and sour a component, - hydrogen sulphide, carbonic gas, etc. The superficial tests stabilized on phase structure oil depending on conditions of preparation for external transport and the subsequent processing can contain this or that quantity of residual hydrogen sulphide, easy hydrocarbons and the lowest sulfhydrates. For change of temperature and external pressure, during transportation and storage the part of easy hydrocarbons and not hydrocarbonic connections (sulfur organic) can be allocated from oil in a gaseous phase and in case of hit in an atmosphere sharply worsens ecology. In the Western Kazakhstan during the years period the temperature of air sometimes reaches up to 40-45 degrees. As is known, at such temperature there is a strengthened warming up of the open surface of oil tanks, that finally leads to increase evaporation easy oil and oil hydrocarbons. With this purpose experiences by quantitative definition evaporation lungs oil and petromixes of the Western Kazakhstan were spent. As a result of the lead works it is found out, that the size of losses at the given fixed temperature depends on evaporation by nature, fractional and hydrocarbonic structures of oil

    2013-01-01

    China is currently in the stage of industrialization and urbanization, which is characterized by rigid energy demand and rapid growth of energy consumption. Therefore, energy conservation will become a major strategy for China in a transition to low-carbon economy. China's transport industry is of high energy consumption. In 2010, oil consumption in transport industry takes up 38.2% of the country's total oil demand, of which 23.6% is taken up by road transport sector. As a result, oil saving in China's road transport sector is vital to the whole nation. The co-integration method is developed to find a long-run relationship between oil consumption and affecting factors such as GDP, road condition, labor productivity and oil price, to estimate oil demand and to predict future oil saving potential in China's transport sector under different oil-saving scenarios. Monte Carlo simulation is further used for risk analysis. Results show that under BAU condition, oil demand of China's road transport sector will reach 278.5 million ton of oil equivalents (MTOE) in 2020. Oil saving potential will be 86 MTOE and 131 MTOE under moderate oil-saving scenario and advanced oil-saving scenario, respectively. This paper provides a reference to establishing oil saving policy for China's road transport sector. - Highlights: • We adopt the co-integration model to estimate oil demand and oil saving potential of China's road transport sector. • Monte Carlo simulation is further used for risk analysis. • GDP, ratio of classified highway, labor productivity and oil price are main factors affecting oil consumption. • Scenario analysis approach is applied to calculate oil saving potential under different energy saving scenarios. • Future policy for oil conservation in China's road transport sector is suggested

  13. Canadian hydrocarbon transportation system : transportation assessment

    International Nuclear Information System (INIS)

    2006-06-01

    This document provided an assessment of the Canadian hydrocarbon transportation system. In addition to regulating the construction and operation of Canada's 45,000 km of pipeline that cross international and provincial borders, Canada's National Energy Board (NEB) regulates the trade of natural gas, oil and natural gas liquids. The ability of pipelines to delivery this energy is critical to the country's economic prosperity. The pipeline system includes large-diameter, cross-country, high-pressure natural gas pipelines, low-pressure crude oil and oil products pipelines and small-diameter pipelines. In order to assess the hydrocarbon transportation system, staff at the NEB collected data from pipeline companies and a range of publicly available sources. The Board also held discussions with members of the investment community regarding capital markets and emerging issues. The assessment focused largely on evaluating whether Canadians benefit from an efficient energy infrastructure and markets. The safety and environmental integrity of the pipeline system was also evaluated. The current adequacy of pipeline capacity was assessed based on price differentials compared with firm service tolls for major transportation paths; capacity utilization on pipelines; and, the degree of apportionment on major oil pipelines. The NEB concluded that the Canadian hydrocarbon transportation system is working effectively, with an adequate capacity in place on existing natural gas pipelines, but with a tight capacity on oil pipelines. It was noted that shippers continue to indicate that they are reasonably satisfied with the services provided by pipeline companies and that the NEB-regulated pipeline companies are financially stable. 14 refs, 11 tabs., 28 figs., 4 appendices

  14. Economic impacts of oil spills: Spill unit costs for tankers, pipelines, refineries, and offshore facilities. [Task 1, Final report

    Energy Technology Data Exchange (ETDEWEB)

    1993-10-15

    The impacts of oil spills -- ranging from the large, widely publicized Exxon Valdez tanker incident to smaller pipeline and refinery spills -- have been costly to both the oil industry and the public. For example, the estimated costs to Exxon of the Valdez tanker spill are on the order of $4 billion, including $2.8 billion (in 1993 dollars) for direct cleanup costs and $1.125 billion (in 1992 dollars) for settlement of damages claims caused by the spill. Application of contingent valuation costs and civil lawsuits pending in the State of Alaska could raise these costs appreciably. Even the costs of the much smaller 1991 oil spill at Texaco`s refinery near Anacortes, Washington led to costs of $8 to 9 million. As a result, inexpensive waming, response and remediation technologies could lower oil spin costs, helping both the oil industry, the associated marine industries, and the environment. One means for reducing the impact and costs of oil spills is to undertake research and development on key aspects of the oil spill prevention, warming, and response and remediation systems. To target these funds to their best use, it is important to have sound data on the nature and size of spills, their likely occurrence and their unit costs. This information could then allow scarce R&D dollars to be spent on areas and activities having the largest impact. This report is intended to provide the ``unit cost`` portion of this crucial information. The report examines the three key components of the US oil supply system, namely, tankers and barges; pipelines and refineries; and offshore production facilities. The specific purpose of the study was to establish the unit costs of oil spills. By manipulating this key information into a larger matrix that includes the size and frequency of occurrence of oil spills, it will be possible` to estimate the likely future impacts, costs, and sources of oil spills.

    This paper reports the experiences acquired through the modifications and improvements implemented in the manufacture, construction and assembly of the oil flow centrifugal pumps of the Osorio-Canoas Oil Pipeline (OSCAN 22''), located in Rio Grande do Sul. The OSCAN 22'' pumping capacity expansion was conceived aiming at meeting the Alberto Pasqualini Refinery (REFAP) processing increase project from 20,000 m{sup 3}/day to 30,000 m{sup 3}/day, besides changing the product profile from processed product to national high viscosity national oils. Due to this reason, a new pump park at the Almirante Soares Dutra Terminal (TEDUT) and a new intermediate pump station named Estacao de Santo Antonio da Patrulha (ESPAT) have been erected. Thus, the oil received by a tanker and stored at TEDUT was now pumped to ESPAT and then to REFAP through a 97 km long and 22 inch diameter oil pipeline named OSCAN 22''. In order to get such oil flow done, 03 new main pumps have been installed at TEDUT, one of them being a stand-by one, and other 03 pumps at ESPAT, one of them being also a stand-by one. During the startup of TEDUT's pumps, high vibration levels were observed in the rotors and in the equipment structures. The values defined by the manufacturer for equipment alarm and shutdown were, respectively, 50.0 {mu}m and 75.0 {mu}m, measured on the pump rotors in the bearing region. However, the global vibration levels of the TEDUT's pumps reached 110.0 {mu}m during the startup attended by the manufacturers. The equipment warranty period started after that, and a detailed activity planning was drawn up with the purpose of keeping TEDUT running with the new pumps at the lowest possible operational risk and avoiding a production reduction at REFAP. Simultaneously, various actions were taken in order to identify the vibration sources and reduce its intensity to the lowest possible values. After equipment modifications, median vibration values at 15

    The under laid gas and oil pipelines on the seafloor are prone to various disturbances like seismic movements of the sea bed, oceanic currents, tsunamis. These factors tend to damage such pipelines connecting different locations of the world dependent on these pipelines for their day-to-day use of oil and natural gas. If damaged, the oil spills in the water bodies cause grave loss to marine life along with serious economic issues. It is not feasible to monitor the undersea pipelines manually because of the huge seafloor depth. For timely detection of such damage, a new technique using optical Fiber Bragg grating (FBG) sensors and its installation has been given in this work. The idea of an FBG sensor for detecting damage in pipeline structure based on the acoustic emission has been worked out. The numerical calculation has been done based on the fundamental of strain measurement and the output has been simulated using MATLAB.

    The use of corrosion inhibitors is spread out in oil and gas industry and is the most common methodology to control pipeline internal corrosion. However, their effectiveness depends on the pipeline material, inhibitor composition, flow type and scale characteristics. When a pipeline has heavy scale deposits, thick bacterial biofilm, or oxygen contamination, the corrosion control via filmic inhibitors is not effective. So, the only way to control internal corrosion of an oil pipeline is to primary identifies the corrosive agent and the main corrosion mechanism. The monitoring of the inhibitor efficiency and the determination of minimal residual concentration to prevent corrosion, are also fundamental. In this paper, is presented the criteria used to identify the main corrosion mechanism of oil pipelines, the treatment proposed in each case and the techniques employed in real time corrosion monitoring.

    2014-01-01

    Full Text Available The present article studies a procedure of calculating the strength of pipeline support constructions of the above-ground oil trunk pipeline system «Zapolyar'e — oil pumping station «Pur-pe». The calculations of the supports stress-strain state are performed with the use of computer complex Ansys v13, which applies the finite element method. The article provides a short description of the construction of fixed, linear-sliding and free-sliding supports of the oil pipeline of above-ground routing, developed for the installation in complex climatic and geologic conditions of the far north. According to the operation specification for design — the support constructions have to maintain the resistance power and bearing capacity under the influence of the pipeline stress without sagging and considering the possible sagging of the neighboring support. The support constructions represent space structures with a complex geometry. Together with the complex geometry, contacting elements are present in the construction of the supports. There is also an interaction of the pile foundation and the nonhomogeneous foundation. The enumerated peculiarities of the construction and operating conditions of the supports considerably complicate the strength calculations by engineering methods. The method of numerical modeling (finite element method used in the article for the analysis of the supports’ operation under the stress is widely applied at the present time for calculations of space structures with a complex geometry. For the first time, while performing the supports’ strength calculations, the article considers the mutual deformation of the support, foundation grill and pile foundation in the ground, thus making it possible to consider real operation of the construction altogether. The main development stages of the calculation model “support — pile foundation — ground” in ANSYS, calculation and testing of the static strength of the support

    For the year 1996, 366 incidents related with clandestine poaching of oil-products were reported in Mexico, 159 in 1997, and 240 in 1998. For the year 2003 (the most recently reported figure), there were 136 events. Petroleos Mexicanos (PEMEX), very concerned with the environmental agenda, has developed programs oriented to diminish contamination levels in all of its oil facilities. This work was aimed at characterizing zones around polyduct segments, pipelines, pumping stations, and right-of-way pipelines located in the center of Mexico. The TPH contaminated sites were, in decreasing order, polyduct km 39 + 150 > polyduct km 25 + 020 > Zoquital > Tepetitlan > Catalina > Venta Prieta > Ceiba. Most of the sampled points showed the presence of more than one of the 16 PAHs considered by USEPA as priority pollutants. Except point TEPE 2A, where no PAHs were detected, all the sampled points showed values from low to medium concentrations; however, values found at the sites did not exceed the limits according to the Mexican or the American legislation. The place with the largest contaminated area corresponded to the polyduct km 39 + 150, with 130 m2 and 260 m3 to be treated. The least contaminated area was that around the JUAN 4 point at Juandho station, with 20 m2 and 22 m3 of contaminated soil. The total area to be treated is about 230 m2 and 497 m3.

    Full Text Available Thermophilic sulfide-producing microorganisms from an oil pipeline network were enumerated with different sulfur oxyanions as electron acceptors at 55 oC. Most-probable number (MPN analysis showed that thiosulfate-reducing bacteria were the most numerous sulfidogenic microorganisms in pipeline inspection gauge (PIG scrapings. Thiosulfate-reducing and methanogenic enrichments were obtained from the MPN cultures that were able to use yeast extract as the electron donor. Molecular analysis revealed that both enrichments harbored the same dominant bacterium, which belonged to the genus Anaerobaculum. The dominant archaeon in the methanogenic enrichment was affiliated with the genus Methanothermobacter. With yeast extract as the electron donor, the general corrosion rate by the thiosulfate-reducing enrichment (8.43 ± 1.40 milli-inch per year, abbreviated as mpy was about 5.5 times greater than the abiotic control (1.49 ± 0.15 mpy, while the comparable measures for the methanogenic culture were 2.03 ± 0.49 mpy and 0.62 ± 0.07 mpy, respectively. Total iron analysis in the cultures largely accounted for the mass loss of iron measured in the weight loss determinations. Profilometry analysis of polished steel coupons incubated in the presence of the thiosulfate-reducing enrichment revealed 59 pits over an area of 71.16 mm2, while only 6 pits were evident in the corresponding methanogenic incubations. The results show the importance of thiosulfate-utilizing, sulfide-producing fermentative bacteria such as Anaerobaculum sp. in the corrosion of carbon steel, but also suggest that Anaerobaculum sp. are of far less concern when growing syntrophically with methanogens.

    The Law 10.233/2001 of 2001 designated the National Agency of Land Transportation (ANTT) as responsible for the gathering and organizing of information about Brazilian pipeline infrastructure. In order to fulfill this legal requirement, ANTT is developing the Brazilian Pipeline Catalog System (SISDUT) and is creating a geo referenced database. The priority is to collect information on the critical points, those where the pipelines intersect with road and rail networks. The SISDUT geo processing catalog will store all information required to manage and track critical points, such as: technical construction standards, as built plans, adjustments terms with roads and rail networks, special usage grants, inspection procedures, pictures taken on local visits, ANTT deliberations, usage of soil, etc. The system was designed using the Object Oriented Analysis and Design paradigms, modeled in the Unified Modeling Language. The database will be populated by ANTT and with data imported from partners. The queries for literal and geographic data will be available on the Internet using Web mapping. SISDUT system will allow spatial cross referencing among its many entities, allowing complex analysis and tracking of events in the critical points. (author)

    2018-02-01

    Acting as a new type of energy transportation mode, the coal pipeline hydraulic transmission can reduce the energy transportation cost and the fly ash pollution of the conventional coal transportation. In this study, the effect of average velocity, particle size and pumping time on particle composition of coal particles during hydraulic conveying was investigated by ring tube test. Meanwhile, the effects of particle composition change on slurry viscosity, transmission resistance and critical sedimentation velocity were studied based on the experimental data. The experimental and theoretical analysis indicate that the alter of slurry particle composition can lead to the change of viscosity, resistance and critical velocity of slurry. Moreover, based on the previous studies, the critical velocity calculation model of coal slurry is proposed.

    This investigation deals with the characterization carried out in zones around two pipeline pumping stations and one pipeline right-of-way in the north of Mexico. In particular those areas where contamination was evaluated: (a) south area of the separation ditch in the Avalos station, (b) the area between the separation ditch at the Avalos station, (c) km 194+420 of the Moctuzma station, and (d) km 286+900 in the Candelaria station. Results of this investigation showed that only four samples showed TPH values higher than the Mexican limit for 2004: AVA 1B, with 21,191 mg kg(-1); AVA 1C, with 9348 mg kg(-1); AVA 2B, with 13,970 mg kg(-1); and MOC 2A, with 4108 mg kg(-1).None of the sampled points showed the presence of PAHs at values higher than those found in the Mexican or American legislations. PAH were detected in the range of 0.0004 and 13.05 mg kg(-1).It is suggested to implement surfactant soil washing as a remediation technique for the approximately 600 m(3) that need to be treated.

    2017-06-01

    Full Text Available Multiphase flow of oil, gas and water occurs in the petroleum industry from the reservoir to the processing units. The occurrence of heavy oils in the world is increasing significantly and points to the need for greater investment in the reservoirs exploitation and, consequently, to the development of new technologies for the production and transport of this oil. Therefore, it is interesting improve techniques to ensure an increase in energy efficiency in the transport of this oil. The core-flow technique is one of the most advantageous methods of lifting and transporting of oil. The core-flow technique does not alter the oil viscosity, but change the flow pattern and thus, reducing friction during heavy oil transportation. This flow pattern is characterized by a fine water pellicle that is formed close to the inner wall of the pipe, aging as lubricant of the oil flowing in the core of the pipe. In this sense, the objective of this paper is to study the isothermal flow of heavy oil in curved pipelines, employing the core-flow technique. A three-dimensional, transient and isothermal mathematical model that considers the mixture and k-e  turbulence models to address the gas-water-heavy oil three-phase flow in the pipe was applied for analysis. Simulations with different flow patterns of the involved phases (oil-gas-water have been done, in order to optimize the transport of heavy oils. Results of pressure and volumetric fraction distribution of the involved phases are presented and analyzed. It was verified that the oil core lubricated by a fine water layer flowing in the pipe considerably decreases pressure drop.

  12. Leakage Risk Assessment of CO{sub 2} Transportation by Pipeline at the Illinois Basin Decatur Project, Decatur, Illinois

    Energy Technology Data Exchange (ETDEWEB)

    Mazzoldi, A.; Oldenburg, C. M.

    2013-12-17

    The Illinois Basin Decatur Project (IBDP) is designed to confirm the ability of the Mt. Simon Sandstone, a major regional saline-water-bearing formation in the Illinois Basin, to store 1 million tons of carbon dioxide (CO{sub 2}) injected over a period of three years. The CO{sub 2} will be provided by Archer Daniels Midland (ADM) from its Decatur, Illinois, ethanol plant. In order to transport CO{sub 2} from the capture facility to the injection well (also located within the ADM plant boundaries), a high-pressure pipeline of length 3,200 ft (975 m) has been constructed, running above the ground surface within the ADM plant footprint. We have qualitatively evaluated risks associated with possible pipeline failure scenarios that lead to discharge of CO{sub 2} within the real-world environment of the ADM plant in which there are often workers and visitors in the vicinity of the pipeline. There are several aspects of CO{sub 2} that make its transportation and potential leakage somewhat different from other substances, most notable is its non-flammability and propensity to change to solid (dry ice) upon strong decompression. In this study, we present numerical simulations using Computational Fluid Dynamics (CFD) methods of the release and dispersion of CO{sub 2} from individual hypothetical pipeline failures (i.e., leaks). Failure frequency of the various components of a pipeline transportation system over time are taken from prior work on general pipeline safety and leakage modeling and suggest a 4.65% chance of some kind of pipeline failure over the three-years of operation. Following the Precautionary Principle (see below), we accounted for full-bore leakage scenarios, where the temporal evolution of the mass release rate from the high-pressure pipeline leak locations was simulated using a state-of-the-art Pipe model which considers the thermodynamic effects of decompression in the entire pipeline. Failures have been simulated at four representative locations along

    Many pipelines are located in remote regions and subjected to harsh environmental conditions. Damage to pipelines can have significant economic and environmental impacts. This paper discussed the use of supervisory control and data acquisition (SCADA) systems to monitor and control oil and gas pipeline infrastructure. SCADA systems are a real time, distributed computerized system with an intelligent capability for condition identification and fault diagnosis. SCADA systems can be used to capture thousands of miles of pipeline system process data and distribute it to pipeline operators, whose work stations are networked with the SCADA central host computer. SCADA architectures include monolithic, distributed, and networked systems that can be distributed across wide area networks (WANs). SCADA security strategies must be implemented to ensure corporate network security. Case studies of SCADA systems currently used by oil and gas operators in Alberta were also presented. 15 refs., 1 fig.

    An efficient management of the natural gas business chain, based on pipeline transmission network and taking into consideration the interaction between the main players such as shippers, suppliers, transmission companies and local distribution companies, requires the use of decision-making support systems to maximize resources and mitigate contingencies due to gas supply shortfalls, operational contingencies from scheduled and non-scheduled equipment outages as well as market demand shortfalls. This work presents a practical utilization of technologies such as thermohydraulic simulation of gas flow through pipelines, Monte Carlo simulation for compressor station availability studies and economic risk evaluation related to potential revenue losses and contractual penalties and linear programming for maximization and minimization objective function. The proposed system allows the definition of the optimum availability level to be maintained by the Transporter, by means of installing redundancy, to mitigate losses related to revenue and contractual penalties. Identifies, quantifies and justifies economically the installation of stand-by compressor units, mitigating Transporter exposure to losses due to capacity shortfalls as consequence of scheduled and non-scheduled outages.

    This paper employs Muthoo's bargaining principles/prerequisites for an effective bargaining result (. A Non-Technical Introduction to Bargaining Theory, World Economics 1(2): 145-166) to decide whether Greece and Bulgaria can form a successful energy coalition. Motivation for this is the proposed construction of the crude oil pipeline from the Bulgarian port Burgas to the Greek Aegean port of Alexandroupolis. The reason Turkey is the third country in the analysis despite its current non-membership in this venture, is that: (i) Turkey offers to host a competitive route of the pipeline, (ii) It is a transit, neighboring country to Greece forming an important geopolitical triangle together with Greece and Bulgaria and (iii) co-operates separately with Bulgaria and Greece in other energy pipelines. Therefore, the three countries engage to interwining energy and geopolitical futures. Whether B-A oil pipeline will be implemented or not, will be due to a mix of bargaining procedures. The paper shows that Muthoo's principles/prerequisites for an effective bargaining result, through their constituents (selected economy and energy figures and characteristics), are fulfilled by Greece and Bulgaria. A broader coalition with the inclusion of Turkey might also be permissible and promising based on this theory. - Research Highlights: →The B-A oil pipeline project is currently at a junction point. Bargaining and public discussion is ongoing. →Muthoo's principles/prerequisites for an effective bargaining result, through their constituents (selected economy, energy, socio-demographic and E-governance figures and characteristics as well as environmental effects and construction characteristics of the pipeline), are fulfilled by Greece and Bulgaria.

  19. Oil and gas pipeline construction cost analysis and developing regression models for cost estimation

    Science.gov (United States)

    Thaduri, Ravi Kiran

    In this study, cost data for 180 pipelines and 136 compressor stations have been analyzed. On the basis of the distribution analysis, regression models have been developed. Material, Labor, ROW and miscellaneous costs make up the total cost of a pipeline construction. The pipelines are analyzed based on different pipeline lengths, diameter, location, pipeline volume and year of completion. In a pipeline construction, labor costs dominate the total costs with a share of about 40%. Multiple non-linear regression models are developed to estimate the component costs of pipelines for various cross-sectional areas, lengths and locations. The Compressor stations are analyzed based on the capacity, year of completion and location. Unlike the pipeline costs, material costs dominate the total costs in the construction of compressor station, with an average share of about 50.6%. Land costs have very little influence on the total costs. Similar regression models are developed to estimate the component costs of compressor station for various capacities and locations.

    Full Text Available Since the beginning of the twenty-first century, there has been widespread construction of submarine oil-gas transmission pipelines due to an increase in offshore oil exploration. Vessel anchoring operations are causing more damage to submarine pipelines due to shipping transportation also increasing. Therefore, it is essential that the influence of anchoring on the required burial depth of submarine pipelines is determined. In this paper, mathematical models for ordinary anchoring and emergency anchoring have been established to derive an anchor impact energy equation for each condition. The required effective burial depth for submarine pipelines has then been calculated via an energy absorption equation for the protection layer covering the submarine pipelines. Finally, the results of the model calculation have been verified by accident case analysis, and the impact of the anchoring height, anchoring water depth and the anchor weight on the required burial depth of submarine pipelines has been further analyzed.

    Gas hydrate deposition can cause plugging in oil and gas pipelines with resultant flow assurance challenges. Presently, the energy industry uses chemical additives in order to manage hydrate formation, however these chemicals are expensive and may be associated with safety and environmental...... concerns. Here we show the effect of a hydrophobically coated surface on hydrate formation in the presence of an antifreeze protein type I (AFP I) and a biodegradable synthetic polymer (LuvicapBio) in a high pressure crystallizer setup. The hydrophobic surface increased the hydrate induction time...... crystallizer. This indicates that 10 to 14 times less KHI is needed in the presence of a hydrophobically coated surface. These experimental studies suggest that the use of hydrophobic surfaces or pipelines could serve as an alternative or additional flow assurance approach for gas hydration mitigation...

    The buried China-Russia Crude Oil Pipeline (CRCOP) across the permafrost-associated cold ecosystem in northeastern China carries a risk of contamination to the deep active layers and upper permafrost in case of accidental rupture of the embedded pipeline or migration of oil spills. As many soil microbes are capable of degrading petroleum, knowledge about the intrinsic degraders and the microbial dynamics in the deep subsurface could extend our understanding of the application of in-situ bioremediation. In this study, an experiment was conducted to investigate the bacterial communities in response to simulated contamination to deep soil samples by using 454 pyrosequencing amplicons. The result showed that bacterial diversity was reduced after 8-weeks contamination. A shift in bacterial community composition was apparent in crude oil-amended soils with Proteobacteria (esp. α-subdivision) being the dominant phylum, together with Actinobacteria and Firmicutes. The contamination led to enrichment of indigenous bacterial taxa like Novosphingobium, Sphingobium, Caulobacter, Phenylobacterium, Alicylobacillus and Arthrobacter, which are generally capable of degrading polycyclic aromatic hydrocarbons (PAHs). The community shift highlighted the resilience of PAH degraders and their potential for in-situ degradation of crude oil under favorable conditions in the deep soils.

    Full Text Available Ground vibrations induced by blasting in the cement quarries are one of the fundamental problems in the quarrying industry and may cause severe damage to the nearby utilities and pipelines. Therefore, a vibration control study plays an important role in the minimization of environmental effects of blasting in quarries. The current paper presents the influence of the quarry blasts at the National Cement Company (NCC on the two oil pipelines of SUMED Company southeast of Helwan City, by measuring the ground vibrations in terms of Peak Particle Velocity (PPV. The seismic refraction for compressional waves deduced from the shallow seismic survey and the shear wave velocity obtained from the Multi channel Analysis of Surface Waves (MASW technique are used to evaluate the closest site of the two pipelines to the quarry blasts. The results demonstrate that, the closest site of the two pipelines is of class B, according to the National Earthquake Hazard Reduction Program (NEHRP classification and the safe distance to avoid any environmental effects is 650 m, following the deduced Peak Particle Velocity (PPV and scaled distance (SD relationship (PPV = 700.08 × SD−1.225 in mm/s and the Air over Pressure (air blast formula (air blast = 170.23 × SD−0.071 in dB. In the light of prediction analysis, the maximum allowable charge weight per delay was found to be 591 kg with damage criterion of 12.5 mm/s at the closest site of the SUMED pipelines.

    2000-01-01

    The feasibility of treating a 1985 pipeline spill of light Pembina Cardium crude oil at a bog near Violet Grove, Alberta was discussed. Pembina Pipeline Corporation arranged for a treatability test to be conducted on oil-contaminated sphagnum peat moss from the site to determine effective in situ or ex situ remediation options for the site. The test was used to evaluate the biodegradation potential of contaminants. Four tests were designed to simulate field different field treatment approaches and to collect critical data on toxicity and leachability of the peat moss. The tests included a bioslurry test, a soil microcosm test, an aerated water saturated peat column test, and a standard toxicity characteristic leachate potential test. The first three tests gave similar results of at least 74 per cent biodegradation of the residual crude oil on the peat solids and no residual toxicity as measured by the Microtox Assay. It was determined that both in situ bioremediation using an aerated water injection system or an ex situ landfarming approach would achieve required criteria and no fertilizers would be necessary to maintain active bioremediation. The new gas-liquid reactor (GLR) aeration technology used in these tests creates a constant supply of hyperoxygenated water prior to column injection. The continuous release of tiny air bubbles maximizes air surface area and increases the gas transfer rates. 3 tabs., 3 figs

    One of the most challenging tasks in an oil field is implementation of a software-based leak detection system on a multi-phase flow pipeline. This paper will discuss implementation of a leak detection system in a particular oil field using state-of-the-art signal processing techniques to apply to the data collected in a oil pipeline. This leak detection system is still in development and uses a more practical approach to the problem than traditional methods and was implemented on a PC under the Windows operating system. Windowing, joint time-frequency analysis and wavelets were considered to develop methods of detecting leaks by watching for the wavefront. The idea behind these techniques is to cut the signal of interest into several parts and then analyze the parts separately. It is impossible to know the exact frequency and the exact time of occurrence of the leak frequency in a signal. In other words, a leak signal can simply not be represented as a point in the time-frequency space. It is very important how one cuts the signal to implement the analysis. The wavelet transform or wavelet analysis is probably the most recent solution to overcome the shortcomings of the Fourier transform. So, this paper shows some tests and how these techniques are being implementing during the development of the system. (author)

    2005-01-01

    The oil transit company, Transpetrol, expects the new Bratislava-Schwechat pipeline connecting the OMV refinery to the Druzba pipeline to increase the use of the pipeline and improve company revenues by 20%. The Austrian project partner, OMV, looks to the project to decrease transportation costs for Russian oil. One sixth of the 60 km pipeline will be built in Slovakia, but there is a problem - the Slovak Ministry of Environment and the City of Bratislava have not approved the route proposed by Transpetrol. In their opinion, the propose route would endanger the protected area, Zitny ostrov, that provides drinking water to the capital. Slovnaft also plans a new pipeline to replace the old obsolete one used to transport its products to the mineral oils transhipment centre at Bratislava docks. One of the alternatives proposed by Slovnaft is the construction of a pipeline and transhipment centre on Zitny ostrov. Unlike the Transpetrol project, this has already received approval from the Ministry of Environment. Before construction work on the pipeline to Schwechat can start. OMV will have resolve issues related to the supply of oil from Russia. According to the original plans, Yukos, which owns a 49% stake in Transpetrol, was to supply the oil. But due to tax problems in Russia, Yukos lost its main drilling division, Juganskneftgaz

    Li, Xinhong; Chen, Guoming; Zhu, Hongwei

    2017-10-15

    This paper develops a 3D, transient, mathematical model to estimate the oil release rate and simulate the oil dispersion behavior. The Euler-Euler method is used to estimate the subsea oil release rate, while the Eulerian-Lagrangian method is employed to track the migration trajectory of oil droplets. This model accounts for the quantitative effect of backpressure and hole size on oil release rate, and the influence of oil release rate, oil density, current speed, water depth and leakage position on oil migration is also investigated in this paper. Eventually, the results, e.g. transient release rate of oil, the rise time of oil and dispersion distance are determined by above-mentioned model, and the oil release and dispersion behavior under different scenarios is revealed. Essentially, the assessment results could provide a useful guidance for detection of leakage positon and placement of oil containment boom. Copyright © 2017 Elsevier Ltd. All rights reserved.

    As a strategic project management with a transport capacity of 31 billion m{sup 3} per year of natural gas, Nabucco 1.0 should diversify the natural gas suppliers for the EU market and the import pipeline network. Significant amounts of natural gas should be imported from the Caspian and the Middle East region. Nabucco 1.0 failed as a project management. The Nabucco consortium wants to convey natural gas through a small-scale and cheaper Nabucco west pipeline via Bulgaria, Romania and Hungary to Austria. Also the Trans-Adriatic Pipeline will transport the same natural gas reserves into the European Union (EU).

    Pipeline leakage during transportation of combustible substances leads to explosion and fire thus causing death of people and destruction of production and accommodation facilities. Continuous pipeline monitoring allows identifying leaks in due time and quickly taking measures for their elimination. The paper describes the solution of identification of pipeline leakage using unmanned aerial vehicles. It is recommended to apply the spectral analysis with input RGB signal to identify pipeline damages. The application of multi-zone digital images allows defining potential spill of oil hydrocarbons as well as possible soil pollution. The method of multi-temporal digital images within the visible region makes it possible to define changes in soil morphology for its subsequent analysis. The given solution is cost efficient and reliable thus allowing reducing timing and labor resources in comparison with other methods of pipeline monitoring.

    Leak detection is always interesting research topic, where leak location and leak rate are two pipeline leaking parameters that should be determined accurately to overcome pipe leaking problems. In this research those two parameters are investigated by developing transmission pipeline model and the leak detection model which is developed using Artificial Neural Network. The mathematical approach needs actual leak data to train the leak detection model, however such data could not be obtained ...

    The failure of a pipeline depends on many causal factors which cannot be predicted with certainty and which even vary by region. For the purposes of consistent traffic route and land use planning it would therefore be desirable to at least be able to estimate the consequential damages of a pipeline rupture. Publications on pipeline accidents are hardly available, at least not in German speaking regions. Where they are, they are usually fire brigade reports. However, these are not sufficient for a documentation of the whole situation. For this reason the Federal Institute for Materials Testing and Research has evaluated a large number of international inspection reports and publications and compiled them into the present research report giving special consideration to the types of risk and in particular consequential damage.

    In this paper we present a surface electromagnetic technology for the non-destructive pipeline coating inspection (SEMPI). This technology allows: determination of the depth and plane position of pipelines, quantitative evaluation of the insulation resistance and delimitation of zones with coating damages, estimation of the performance of the cathodic protection system (CPS) and detection of its connections to out-of-service pipes and other grounded constructions, and assessment of the soil aggressively. The SEMPI technology is based on the approximation of pipelines by heterogeneous transmission lines with variable leakage conductance and pipe impedance to represent insulation coating and wall thickness damages. Based on the result of simulations, we have optimized the field measurements and developed the interpretation procedure of experimental data. The field operations include surface measurements of magnetic field, voltage on the control posts of the CPS and soil resistivity. In zones with coating damages the detailed measurements can be performed using magnetic or electric field to increase the resolution in localizing and evaluating the insulation damages. The SEMPI technology has been applied for inspections of pipelines with different technical characteristics in complicated environmental conditions. The examples presented in this work confirm the high efficiency of the developed technology for external integrity evaluation of pipelines. (author)

    Full Text Available Improving leak detection capability to eliminate undetected releases is an area of focus for the energy pipeline industry, and the pipeline companies are working to improve existing methods for monitoring their pipelines. Computer model-based leak detection methods that detect leaks by analyzing the pipeline hydraulic state have been widely employed in the industry, but their effectiveness in practical applications is often challenged by real-world uncertainties. This study quantitatively assessed the effects of uncertainties on leak detectability of a commonly used real-time transient model-based leak detection system. Uncertainties in fluid properties, field sensors, and the data acquisition system were evaluated. Errors were introduced into the input variables of the leak detection system individually and collectively, and the changes in leak detectability caused by the uncertainties were quantified using simulated leaks. This study provides valuable quantitative results contributing towards a better understanding of how real-world uncertainties affect leak detection. A general ranking of the importance of the uncertainty sources was obtained: from high to low it is time skew, bulk modulus error, viscosity error, and polling time. It was also shown that inertia-dominated pipeline systems were less sensitive to uncertainties compared to friction-dominated systems.

  5. Transportation in the future : blind side of the oil market

    2002-01-01

    The first oil embargo of 1974 and the oil crisis of 1979/1980 demonstrated that of all sectors, the transportation sector is the most threatened by abrupt changes in fuel prices. For that reason, the International Energy Agency (IEA) and member countries have strived to develop a good set of analytical tools for forecasting future energy demand in transportation. This presentation addressed issues regarding oil demand and explained why it may never be the same. Oil demand has been changed by the imposition of fuel economy standards in North America, voluntary agreements to limit fuel consumption in Europe, and the freight related component. Motor vehicle ownership is growing significantly in developing countries. Neither oil problems nor carbon dioxide emissions will slow that growth for a long time to come. Traffic congestion and pollution are major problems in most of the developing world. Therefore, policies to save oil or reduce carbon dioxide emissions should be integrated with strategies to improve transportation and clean the air in developing countries. New incentives may include clean vehicles, fuel efficiency, clean and low carbon fuels, and transportation planning. The paper also described how information technology, such as use of the Internet, is a low energy product that can boost economic activity and which in the future, may have a broader impact on transportation. It was concluded that while transportation energy is driven by economic growth, it can be impacted by higher prices and by energy policies. 16 figs

    New deterministic and stochastic predictive models are proposed for external pitting corrosion in underground pipelines. The deterministic model takes into consideration the local chemical and physical properties of the soil as well as the pipeline coating to predict the time dependence of pitting depth and rate in a range of soils. This model, based on results from a field study, was used to conduct Monte Carlo simulations that established the probability distribution of pitting depth and growth rate in the studied soils and their evolution over the life of the pipeline. In the last stage of the study, an empirical Markov chain-based stochastic model was developed for predicting the evolution of pitting corrosion depth and rate distributions from the observed properties of the soil.

  7. Induced electric currents in the Alaska oil pipeline measured by gradient, fluxgate, and SQUID magnetometers

    1979-01-01

    The field gradient method for observing the electric currents in the Alaska pipeline provided consistent values for both the fluxgate and SQUID method of observation. These currents were linearly related to the regularly measured electric and magnetic field changes. Determinations of pipeline current were consistent with values obtained by a direct connection, current shunt technique at a pipeline site about 9.6 km away. The gradient method has the distinct advantage of portability and buried- pipe capability. Field gradients due to the pipe magnetization, geological features, or ionospheric source currents do not seem to contribute a measurable error to such pipe current determination. The SQUID gradiometer is inherently sensitive enough to detect very small currents in a linear conductor at 10 meters, or conversely, to detect small currents of one amphere or more at relatively great distances. It is fairly straightforward to achieve imbalance less than one part in ten thousand, and with extreme care, one part in one million or better.

  8. Developing a pipeline risk assessment tool for the upstream oil and gas industry

    2010-07-01

    This paper described an in-house pipeline risk assessment process developed by Talisman Energy. The semi-quantitative methodology was used to identify high-risk pipelines. The first phase of the methodology consisted of determining only the consequence of failures, while the second phase included a detailed, more traditional approach that considered consequences and the likelihood of failure. A mathematical algorithm was developed to generate a final consequence score between 0 and 4. The algorithm combined both public concern and environmental concern scores to form a base value for the health and safety score. A production score was then factored in to yield an overall consequence score. The algorithm yielded results consistent with real pipeline failure consequences. Phase 2 considered internal and external corrosion likelihood, historical likelihood, third party damage likelihood. and geotechnical likelihood. A cascading approach was to yield an overall likelihood score. Examples of the methodology were included. 9 refs., 1 tab., 6 figs.

    2017-01-01

    To protect the pipelines from significant danger, the acoustic leak detection and location method for oil and gas pipelines is studied, and a de-noising system is established to extract leakage characteristics from signals. A test loop for gas and oil is established to carry out experiments. First, according to the measured signals, fitting leakage signals are obtained, and then, the objective signals are constructed by adding noises to the fitting signals. Based on the proposed evaluation indexes, the filtering methods are then applied to process the constructed signals and the de-noising system is established. The established leakage extraction system is validated and then applied to process signals measured in gas pipelines that include a straight pipe, elbow pipe and reducing pipe. The leak detection and location is carried out effectively. Finally, the system is applied to process signals measured in water pipelines. The results demonstrate that the proposed de-noising system is effective at extracting leakage signals from measured signals and that the proposed leak detection and location method has a higher detection sensitivity and localization accuracy. For a pipeline with an inner diameter of 42 mm, the smallest leakage orifice that can be detected is 0.1 mm for gas and water and the largest location error is 0.874% for gas and 0.176% for water. - Highlights: • Three evaluation indexes are proposed: SNR, RMSE and ALPD. • The de-noising system is established in the gas and oil pipelines. • The established system is used for gas pipeline effectively, including interference pipes. • The established de-noising system is used for water pipeline effectively.

    2005-01-01

    Environmentally sound decommissioning practices in the remediation and reclamation process were reviewed, with reference to abandoned oil and gas facilities and pipelines. There are inherent dangers associated with aged infrastructure, and decommissioning companies should be the first service on site to ensure that all facilities have been located, removed and cleaned. All licensed, unlicensed and on-lease pipelines are required to be properly abandoned. Site research is needed to identify any industry or government regulated requirements that may impact the decommissioning process. Decommissioning companies are also responsible for recording all relevant site information so that it can be conveyed to remediation and reclamation companies. A knowledge of landowner sensitivities, weather affected access, unlicensed facilities and locations of historic contamination are crucial to all parties involved. Additional documentation, such as photographs and survey drawings, can assist remediation and reclamation companies in locating areas of concern. Once a well has been abandoned in Alberta, surface equipment, cement pads, debris and produced liquids associated with the well license must be removed within 12 months of the cutting and capping operation. Records of the removal and cleanup activities must be retained by the licensee. Many sites have been sitting dormant for several years and can be harboring dangerous production fluids, asbestos, Hantavirus and other hazardous materials. All equipment must be steam-cleaned by qualified personnel and all production fluids and contaminated water from the cleaning process must be captured and transported to a waste facility. All equipment that is deemed re-usable can be returned to inventory or re-used. Equipment that can not be salvaged is sold for recycling at a steel mill. All pipelines are required to be cleaned of hydrocarbons, purged and left with a medium of inert gas or atmospheric air. Residual fluids left in a

To take a planned long-distance gas pipeline as an example, the assessment method and principles for coal resources covered by linear projects are introduced. The areas covered by multiple coal seams are determined according to the linear projection method, and the resources covered by pipelines directly and indirectly are estimated by using area segmentation method on the basis of original blocks. The research results can provide references for route optimization of projects and compensation for mining right..

    The Caspian Sea basin holds large quantities of both oil and natural gas that could help meet the increasing global demand for energy resources. Consequently, the oil and gas potential of the region has attracted the attention of the international oil and gas industry. The key to realizing the energy producing potential of the region is the development of transnational export routes to take oil and gas from the landlocked Caspian Sea basin to world markets. The evaluation and selection of alternative transnational export routes is a complex multi-criteria problem with conflicting objectives. The decision makers (DMs) are required to consider a vast amount of information concerning internal strengths and weaknesses of the alternative routes as well as external opportunities and threats to them. This paper presents a hybrid model that combines strength, weakness, opportunity and threat (SWOT) analysis with the Delphi method. - Highlights: ► The evaluation and selection of the pipeline routes is a multi-criteria problem. ► A hybrid SWOT-Delphi method is proposed to evaluate five potential routes. ► The Southern and Northern routes are chosen as the best and second-best options. ► The second best option is identified to provide some degree of diversification.

    2007-01-01

    In this paper, the transport and distribution aspects of hydrogen during the transition period towards a possible full-blown hydrogen economy are carefully looked at. Firstly, the energetic and material aspects of hydrogen transport through the existing natural-gas (NG) pipeline infrastructure is discussed. Hereby, only the use of centrifugal compressors and the short-term security of supply seem to constitute a problem for the NG to hydrogen transition. Subsequently, the possibility of percentwise mixing of hydrogen into the NG bulk is dealt with. Mixtures containing up to 17 vol% of hydrogen should not cause difficulties. As soon as more hydrogen is injected, replacement of end-use applications and some pipelines will be necessary. Finally, the transition towards full-blown hydrogen transport in (previously carrying) NG pipelines is treated. Some policy guidelines are offered, both in a regulated and a liberalised energy (gas) market. As a conclusion, it can be stated that the use of hydrogen-natural gas mixtures seems well suited for the transition from natural gas to hydrogen on a distribution (low pressure) level. However, getting the hydrogen gas to the distribution grid, by means of the transport grid, remains a major issue. In the end, the structure of the market, regulated or liberalised, turns out not to be important. (author)

    The geopolitical background to the export of oil and gas from Kazakhstan by pipeline is explored with particular reference to the sensitivities of the USA. There are now a number of pipeline proposals which would enable Kazakhstan to get its hydrocarbons to world markets. The construction of two of these formed part of a major oil deal signed recently with China in the face of stiff competition from major US companies. The most convenient and cost effective route, connecting up with Iran's existing pipeline network to the Gulf, is unlikely to be developed given continuing US sanctions against Iran. Equally unlikely seems to be the Turkmenistan to Pakistan pipeline in the light of the political volatility of Afghanistan. US companies continue to face limits on export capacity via the existing Russian pipelines from Kazakhstan. A temporary solution could be to carry some oil in the existing pipeline from Azerbaijan to Georgia which has been upgraded and is due to become operational soon, and later in a second proposed pipeline on this route. The Caspian Pipeline Consortium, consisting of three countries and eleven international companies, is building a 1500 km pipeline from the Tergiz field to Novorossiysk on the Black Sea with a view to completion in 2000. An undersea pipeline crossing the Caspian from Azerbaijan is being promoted by Turkey. There is an international perception that within the next five years Kazakhstan could be in a position to export its oil via as many as half a dozen different routes. (UK)

    Advanced geochemical soil gas methods have been successfully developed for the exploration of oil/gas/uranium and for environmental assessments. Application of these cost-effective technologies in India can substantially reduce exploration risk while accelerating the development of oil/gas/uranium onshore resources. A reliable and effective monitoring system using geochemical soil gas surveys ensures that CO 2 Enhanced Oil Recovery operations as well as CO 2 sequestration projects are safe and acceptable for the disposal of CO 2 , Soil gas surveys along with other technologies can also be applied for monitoring of oil/gas pipelines for leakage, especially those that are old or pass through populated regions

    The transportation of natural gas, oil and other commodities is effected by pipelines throughout most of the country. Safety in the vicinity of a pipeline is very important because damage to a pipeline could result in adverse conditions to public safety and/or the environment. Before digging, written approval must be obtained from the pipeline company. If a landowner is having difficulty negotiating an agreement with the pipeline company, they should call the National Energy Board. It is illegal to construct or excavate without authorization, and approval or denial of a request must be granted within 10 business days by the pipeline company. Three days are allowed to the pipeline company to locate its pipeline. A section dealing with pipeline right-of-way is included, as well as the safety zone and the restricted area. A 10-step checklist of safety tips assists the landowner in taking the appropriate measures in the vicinity of a pipeline. A brief overview of the responsibilities of the National Energy Board is provided, followed by a list of the main pipelines regulated by the National Energy Board. 2 figs

  6. An integrated multi−period planning of the production and transportation of multiple petroleum products in a single pipeline system

    2011-01-01

    Full Text Available A multiproduct pipeline provides an economic way to transport large volumes of refined petroleum products over long distances. In such a pipeline, different products are pumped back−to−back without any separation device between them. The sequence and lengths of such pumping runs must be carefully selected in order to meet market demands while minimizing pipeline operational costs and satisfying several constraints. The production planning and scheduling of the products at the refinery must also be synchronized with the transportation in order to avoid the usage of the system at some peak−hour time intervals. In this paper, we propose a multi−period mixed integer nonlinear programming (MINLP model for an optimal planning and scheduling of the production and transportation of multiple petroleum products from a refinery plant connected to several depots through a single pipeline system. The objective of this work is to generalize the mixed integer linear programming (MILP formulation proposed by Cafaro and Cerdá (2004, Computers and Chemical Engineering where only a single planning period was considered and the production planning and scheduling was not part of the decision process. Numerical examples show how the use of a single period model for a given time period may lead to infeasible solutions when it is used for the upcoming periods. These examples also show how integrating production planning with the transportation and the use of a multi−period model may result in a cost saving compared to using a single−period model for each period, independently.

  7. Time-Varying Hydraulic Gradient Model of Paste-Like Tailings in Long-Distance Pipeline Transportation

    2017-01-01

    Full Text Available Paste-like tailings slurry (PTLS is always simplified as a Bingham plastic fluid, leading to excessive computational errors in the calculation of the hydraulic gradient. In the case of paste-like tailings in long-distance pipeline transportation, to explore a high-precision and reliable hydraulic gradient formula, the rheological behavior of paste-like tailings slurry was analyzed, a time-varying hydraulic gradient model was constructed, and a series of laboratory shear tests were conducted. The results indicate that the PTLS shows noticeable shear-thinning characteristics in constant shear tests; the calculated hydraulic gradient declined by about 56%, from 4.44 MPa·km−1 to 1.95 MPa·km−1 within 253 s, and remained constant for the next four hours during the pipeline transportation. Comparing with the balance hydraulic gradient obtained in a semi-industrial loop test, the computational errors of those calculated by using the time-varying hydraulic gradient model, Jinchuan formula, and Shanxi formula are 15%, 78%, and 130%, respectively. Therefore, our model is a feasible and high-precision solution for the calculation of the hydraulic gradient of paste-like tailings in long-distance pipeline transportation.

    The deposition of paraffins in submarine pipelines poses a serious problem for the offshore petroleum production. Paraffins precipitate off oily solutions due to a temperature decrease according to the phase equilibrium conditions of the liquid-solid system. After some time, the continuous precipitation leads to deposits in the internal walls of the pipe, clogging the lines and promoting an increase in the head loss of the flow. Consequently, there is an increase in the pressure gradient required to maintain the flow, and the flow rate is reduced. A complete obstruction of the pipeline may occur. In the present work, this phenomenon was studied in a simulation of the subsea operational conditions, where the oil pipelines laying on the seabed are subjected to low temperatures, just a little above the freezing point of water. The pipeline behaves as a heat exchanger and the hot oil from the underground reservoir emerging from the wellhead is effectively cooled down to the point where paraffin precipitation occurs somewhere along the line. An experimental apparatus was built for a 25.4 mm (1 in) diameter pipe-flow model with 13 m of length, submerged in a chilling bath of near frozen water. Stream wise pressure and temperature gradients were measured, in order to evaluate the differences in the behavior of paraffin deposition between one-phase oil flow and two-phase oil-water flow.

    Before reaching the ocean surface, the oil and gas released from the DWH MC 252 blowout at 1500 m moves as a buoyant plume until the trapping depth and plume transition point are reached (Zheng et al 2002). At the transition point, the oil droplets and bubbles move independently of each other, and rise at a rate related to their diameter. The oil density, droplet size distribution and currents primarily determine the distribution of the oil between: Large droplets that rise quickly and create a surface expression of the oil. Moderate size droplets that rise over the course of days, and so spread out quite differently than the surface oil, and commonly do not reach the surface in large enough quantities to create a surface sheen. These droplets separate in the currents, particularly in the strong current shear in upper 500 m currents. Very tiny droplets that rise very slowly, over the course or weeks to months, and may be removed by dissolution, biodegradation or marine snow before ever reaching the surface. Modeling and observations (Joint Analysis Group, 2010) confirm the presence of a deep layer of oil and gas between approximately 1100 and 1300 m over the release location and spreading out along the isopycnal surfaces. Later in the event, a small oxygen depression was a proxy for where oil and gas had been. The DWH MC252 well is located at intermediate depth in the Gulf of Mexico (GoM). The water mass is Antarctic Intermediate Water, which enters and exits the GoM through the Yucatan Straits. Surface influences, such as Loop Current Frontal Eddies (e.g. Berger et al 2000) can reach down to these depths, and alter the flow within De Soto Canyon. The water mass containing the deep layer of oil droplets changes depth within the GoM, but does not reach above a depth of about 900 m. There are no physical processes that could cause this deep layer of oil to reach the continental shelf or the Florida Straits. Observed and historical hydrographic data, observations

    Full Text Available Whereas geomagnetically induced currents are a source of problems for technological systems mainly at high geomagnetic latitudes, strong geomagnetic disturbances can have quite strong effects even at mid-latitudes. This paper deals with the analysis of the pipe-to-soil (P/S voltage measured in oil pipelines in the Czech Republic during the Halloween magnetic storms in 2003. It is shown that the simplest - plane wave and uniform Earth-model of the electric field corresponds well to the measured P/S voltage. Although the largest amplitudes of the geomagnetic field were reached on the onset of the geomagnetic storm, large voltages were also induced in the main and recovery phases due to Pc5 oscillations.

    The thermal stability of palm oil as energy transport media in a hydraulic system was studied. The oils were aged by circulating the oil in an open loop hydraulic system at an isothermal condition of 55 deg. C for 600 h. The thermal behavior and kinetic parameters of fresh and degraded palm oil, with and without oxidation inhibitor, were studied using the dynamic heating rate mode of a thermogravimetric analyser (TGA). Viscometric properties, total acid number and iodine value analyses were used to complement the TGA data. The thermodynamic parameter of activation energy of the samples was determined by direct Arrhenius plot and integral methods. The results may have important applications in the development of palm oil based hydraulic fluid. The results were compared with commercial vegetable based hydraulic fluid. The use of F10 and L135 additives was found to suppress significantly the increase of acid level and viscosity of the fluid

    Transportation of liquids is a primary aspect of human life. The most important infrastructure used accordingly is the pipeline. It serves as an asset for transporting different liquids and strategic goods. The latter are for example: chemical substances, oil, gas and water. Thus, it is necessary to monitor such infrastructures by means of specific tools. Leakage detection methods are used to reveal liquid leaks in pipelines for many applications, namely, waterworks, oil pipelines, industry heat exchangers, etc. The configuration of pipelines is a key issue because it impacts on the effectiveness of the method to be used and, consequently, on the results to be counterchecked. This research illustrated an improvement of the impedance method for zigzag pipeline by carrying out an experimental frequency analysis that has been compared with other methods based on frequency response. Hence, the impedance method is generally used for simple (straight) pipeline configurations because complicated pipelines with many curves introduce difficulties and major uncertainties in the calculation of characteristic impedance and in the statement of boundary conditions. The paper illustrates the case of a water pipeline where the leakage is acquired thanks to pressure transducers.

    Full Text Available In the simulation of oil-gas pipeline multiphase flow, thermodynamic computation is an important process interacting with the hydraulic calculation and it influences the convergence of the program and the accuracy of the results. The form of the energy equation is the key to the thermodynamic computation. Based on the energy equation of oil-gas flow in pipeline, the Explicit Temperature Drop Formula (ETDF is derived for oilgas steady state temperature calculation. This new energy equation has considered many factors, such as Joule-Thomson effect, pressure work, friction work and impact of terrain undulation and heat transfer Oil & Gas Science and Technology – Rev. IFP Energies nouvelles with the surroundings along the line. So it is an overall form of energy equation, which could describe the actual fact of multiphase pipeline accurately. Therefore, some standpoints in literatures on the temperature calculation of oil-gas two-phase flow in pipelines are reviewed. Elimination of temperature iteration loop and integration of the explicit temperature equation, instead of enthalpy energy equation, into the conjugated hydraulic and thermal computation have been found to improve the efficiency of algorithm. The calculation applied to both the component model, also applied to the black-oil model. This model is incorporated into the component model and black-oil model, respectively, and two simulations are carried out with two practical pipeline Yingmai-Yaha and Lufeng multiphase pipeline and the temperature results are compared with the simulation calculated by the OLGA and the measured. It is shown that this model has simulated the temperature distribution very well. Finally, we analyzed the influence of the specific heat capacity of oil and gas on the temperature of the mixture of fluids and the influence of the Joule-Thomson effect on the temperature distribution on the pipeline. It is shown that the Joule-Thomson coefficient is a key factor to

    Fluid in a pipeline or container at a refinery or at any of various petroleum producing operations is bombarded with neutrons and high energy gamma rays resulting from capture of thermal neutrons are detected. The spectra of the detected gamma rays are then analyzed to determine the concentration of the element chlorine, which gives an indication of the presence and concentration of salt water in the fluid. The concentration of sulfur and the percentage gas in the fluid may be determined simultaneously with the concentration of chlorine. (Auth.)

    The Rio de Janeiro is one of 27 units of Brazil. It is located in the eastern portion of the Southeast and occupies an area of 43 696.054 km², being effectively the 3rd smallest state in Brazil. This state in recent years has suffered from erosion problems caused by the deployment of the network pipeline. The deployment pipeline is part of the activities related to the oil industry has caused a more intense conflict between the environment and economic activities, modifying the soil structure and distribution of surface and subsurface flows. This study aimed to analyze the erosion caused by the removal of soil for the deployment of pipeline transportation, with the consequences of the emergence of numerous gullies, landslides and silting of rivers. For the development of this study were performed bibliographic research, field work, mapping and digital preparation of the initial diagnosis of active processes and what the consequent environmental impacts. For these reasons, we conclude that the problems could be avoided or mitigated if there was a prior geological risk management. (author)

    2009-10-01

    Four pipeline projects have been proposed for northern British Columbia that could threaten the health of the Fraser, Skeena, and Kitimat watersheds. The pipelines will expose salmon to risks on several fronts. Enbridge's Northern Gateway pipeline project has generated the most concern for a several reasons, including the risks to salmon and freshwater habitat from pipeline failures, notably leaks or ruptures. This paper reviewed the salmon resources in affected watersheds; salmon and BC's economy; salmon diversity and abundance; impacts on fish from pipeline construction, operations and failures; behaviours of different petroleum products in fresh water; hydrocarbon toxicity; history of pipeline failures; sabotage and natural disasters; and Canadian case studies. Salmon are already experiencing stresses from forestry, hydro-electricity, transportation, agriculture, mining, mountain pine beetle, climate change and coalbed methane development. Their cumulative impact will dictate the long-term health and viability of salmon. It was concluded that if all of the proposed pipelines were built, they would extend over 4,000 km, crossing more than 1,000 rivers and streams in some of Canada's most productive salmon habitat. During construction, pipeline stream crossings are vulnerable to increased sedimentation, which can degrade salmon habitat. In the event of a spill, the condensate and oil sands products carried in the pipelines are highly toxic to salmon, with serious and lasting adverse impacts on salmon and their habitat. Any decision to approve such a pipeline should be made in recognition of these risks. 73 refs., 5 tabs., 15 figs., 2 appendices.

    The continuous pipeline operators training and certification of the TRANSPETRO's Pipeline National Operations Control Center (CNCO) is an essential task aiming the efficiency and safety of the oil and derivatives transport operations through the Brazilian pipeline network. For this objective, a hydraulic simulator is considered an excellent tool that allows the creation of different operational scenarios for training the pipeline hydraulic behavior as well as for testing the operator's responses to normal and abnormal real time operational conditions. The hydraulic simulator is developed based on a pipeline simulation software that supplies the hydraulic responses normally acquired from the pipeline remote units in the field. The pipeline simulation software has a communication interface system that sends and receives data to the SCADA supervisory system database. Using the SCADA graphical interface to create and to customize human machine interfaces (HMI) from which the operator/instructor has total control of the pipeline/system and instrumentation by sending commands. Therefore, it is possible to have realistic training outside of the real production systems, while acquiring experience during training hours with the operation of a real pipeline. A pilot Project was initiated at TRANSPETRO - CNCO targeting to evaluate the hydraulic simulators advantages in pipeline operators training and certification programs. The first part of the project was the development of three simulators for different pipelines. The excellent results permitted the project expansion for a total of twenty different pipelines, being implemented in training programs for pipelines presently operated by CNCO as well as for the new ones that are being migrated. The main objective of this paper is to present an overview of the implementation process and the development of a training environment through a pipe simulation environment using commercial software.

    An experimental study, as well as theoretical and numerical models, are used to validate a methodology to exploit conventional geochemical data with regard to the concentration profiles of organic components occurring naturally in hydrocarbon reservoir oils. The experiment was designed to study transport of organic compounds from immobile oil during water injection. A homogeneous oil-filled core sample was made heterogeneous by drilling a hole through its central axis and filling it with a highly permeable material. Under the present conditions, diffusion coefficients are the most important parameters controlling the transport, and the effect of partitioning could be accounted for by a simple normalization. The experimental results are well described by a simple 2-D analytical model which assumes instantaneous removal of solutes from the oil-water interface. The experimental results are also well described by two numerical models, of which one is a full featured reservoir scale model, suitable for applications of the methodology to reservoir scale cases.

    Full Text Available In the contemporary world, despite the growing importance and scale of the use of renewable energy , conventional energy resources still play a huge role. The European Union countries are dependent on the oil imports and the their main supplier of crude oil and natural gas has been the Russian Federation. After the collapse of the Soviet Union , the Caspian Sea region has become an alternative to Russian energy resources. The Unit-ed States , European Union, China and many other countries have shown their interest about this region. Despite a relatively large oil and natural gas reserves, the export of the-se commodities to the West is still problematic. Based on the available data and infor-mation, the publication explores the issue of energy resources transport directions with a particular emphasis on the crude oil from the Caspian Sea region to Europe.

    The Trans-Ecuadorian Pipeline carries crude oil from oilfields in eastern Ecuador to refineries on the Pacific coast, crossing the Páramo region, an alpine tundra ecosystem within the province of Pichincha, which also serves as the water supply for the capital city of Quito. The objective of this study has been to create a model for predicting the likelihood that the effects of a crude oil spill in the Páramo region would impact the water supply of Quito by comparing the residence times of organic compounds in soil with the time required for microbial degradation. A custom MATLAB script included linear partitioning of multiple organic compounds among the water, air, soil and NAPL phases. The three organic compounds considered were anthracene, benzene, and naphthalene. The relevant soil parameters for the Páramo region were obtained from the ISRIC-WISE Harmonized Global Soil Profile Dataset. The soil organic matter content is a critical parameter that was estimated from a very small number of measurements. Residence time half-lives were calculated for depths of penetration of the initial spill ranging from 0.1-5 m. For a depth of penetration of 1 m, residence time half-lives for benzene, naphthalene and anthracene were 1.5, 23.1 and 247.8 years, respectively. Comparing with typical biodegradation half-lives of 10-730 days for benzene, 1-258 days for naphthalene, and 199-252 days for anthracene, it can be seen that penetration to groundwater and transport to the reservoir that supplies water to Quito is unlikely for naphthalene and anthracene, but is a distinct possibility for benzene. Current modeling involves including the effect of volatilization within the soil and improving the estimates of biodegradation rates within an alpine tundra ecosystem. Further results will be reported at the meeting.

    European Union is interested also like USA to lower its own dependence on oil distributors from problematic region of Persian Gulf. Therefore the attention is turning on to Russia and to region of Caspian Sea. However except political and safety problems the import of oil from these territories meets also the lack of transport capacities. Slovakia can become the important transit territory, where could flow more Russian or Caspian oil to the European market. After a break-up of Soviet Union Russia lost oil export terminals on the coast of Baltic Sea. These terminals became a part of territories of three independent Baltic countries. The frequent storms in the region of Novorossiysk are disadvantage of Black Sea's ports Novorossiysk and Tuapse. The overloading of Turkish straits Bospor and Dardanely, which connect Black Sea and Mediterranean Sea, is becoming a new and more serious problem. In the present time up to 500 tankers swim over through these straits annually, which transport together around 70 million tones of oil and of oil products. Owing to the rising mining of oil the only one way out is the circumvention of these straits. New pipeline from Baku through Georgia to Turkish terminal Ceyhan on the coast of Mediterranean Sea is the only one but not sufficient solution. Therefore Russia promotes the project of integration of pipelines Druzba and Adria. The intensions is to open the continuous export pipeline way through Belarus, Ukraine, Slovakia and Hungary into Croatian terminal Omisajl on the coast of Adriatic Sea. Other possibility how to rise the oil transit through Slovakia is the construction of pipeline to the refinery OMW in Schweechat near Vienna. In the end of the last year the representatives of Transpetrol, Yukos and OMW signed the contract of its construction in Bratislava. Annual capacity of this pipeline is 2 million tonnes of oil. Other possibility how to transport the Caspian oil is pipeline Odessa-Brody. More then 600 km of this pipeline

    The wheel test provides good mixing of the condensate and water phases, the coupons are exposed to both phases. Therefore, the wheel test cannot distinguish between inhibitors that need continuous mixing of the these phases to maintain a water dispersion of the inhibitor and inhibitors that will self disperse into the water. This concept becomes important for pipelines in stratified flow where the water can settle out. In these cases with low turbulence, the inhibitor must self disperse into the water to be effective. The paper describes a test method to measure the effectiveness of an inhibitor and its ability to self disperse. The effectiveness of several inhibitors as predicted by the new test method is discussed relative to data from the wheel test and breaker tests. Field performance of these inhibitors in a gas gathering line, with liquids in stratified flow, are cities and compared with the results of the various laboratory tests.

    In this study, we propose a method for estimating the amount of expansion that occurs in subsea pipelines, which could be applied in the design of robust structures that transport oil and gas from offshore wells. We begin with a literature review and general discussion of existing estimation methods and terminologies with respect to subsea pipelines. Due to the effects of high pressure and high temperature, the production of fluid from offshore wells is typically caused by physical deformation of subsea structures, e.g., expansion and contraction during the transportation process. In severe cases, vertical and lateral buckling occurs, which causes a significant negative impact on structural safety, and which is related to on-bottom stability, free-span, structural collapse, and many other factors. In addition, these factors may affect the production rate with respect to flow assurance, wax, and hydration, to name a few. In this study, we developed a simple and efficient method for generating a reliable pipe expansion design in the early stage, which can lead to savings in both cost and computation time. As such, in this paper, we propose an applicable diagram, which we call the standard dimensionless ratio (SDR) versus virtual anchor length (L A ) diagram, that utilizes an efficient procedure for estimating subsea pipeline expansion based on applied reliable scenarios. With this user guideline, offshore pipeline structural designers can reliably determine the amount of subsea pipeline expansion and the obtained results will also be useful for the installation, design, and maintenance of the subsea pipeline.

    According to Revista Brasil Energia (2011a), the local natural gas distribution concessionaire in the State of Sao Paulo Gas Brasiliano Distribuidora - GBD, plans to expand its distribution pipeline network in western Sao Paulo up to the border of the State of Minas Gerais, near the region known as Minas Triangle where a connection with the pipeline network of the State of Minas Gerais' natural gas distribution company, Companhia de Gas de Minas Gerais - GASMIG shall be built in order to supply natural gas to an ammonia plant to be built by PETROBRAS in the City of Uberaba. Still according to the publication, the project described above would be an alternative to the construction of a transportation pipeline that, since the enforcement of the Gas Law - Law No. 11.909/09 (Brasil, 2009), should be subject to concession contracts preceded by a complex, and probably delayed, planning and procurement. However, there is a transportation pipeline project, deriving from the Bolivia-Brazil transportation pipeline near the city of Sao Carlos, in Sao Paulo, crossing the Minas Triangle and finishing in the State of Goias. This project is owned by TGBC Company. The existence of two gas pipeline projects with very similar paths to supply virtually the same regions and based on different regulatory frameworks, one consisting of a connection between the distribution networks of different States and another based on the concept of pipeline transportation of gas under the legal and regulatory federal jurisdiction raises the discussion about the possibility of legal and regulatory interstate connections of distribution pipeline networks as an alternative to planning, allocation and construction of a transportation pipelines. This article aims to examine the legal and regulatory foundations of both alternatives and delineate the limits of performance of States and Federal Government on legislation and regulation concerning the movement of natural gas pipeline through the Country

    During the design stage of a thermal heavy oil pipeline, the design engineer should include the consideration of more factors than what is normally used for the design of a conventional pipeline. In the Steam Assisted Gravity Drainage (SAGD) production, for the extraction of bitumen from oily soil, it is required that a stream of hot and pressurized steam (over 300 deg C) to be injected into the oil reservoir. The steam reaches the oily soil reservoir from a steam sour such as boilers by traveling through above-ground pipeline arrangements. As a result of the steam injection into the well site, bitumen oil is released from the oily soil. The produced bitumen also consists of high pressure and temperature (over 200 deg C) and requires a gathering pipeline arrangement for traveling to the processing plant. During the layout design, both steam injection and hot production lines are usually designed parallel with each other by using a series of anchor-loop-anchor supported by steel structures and pilings. The coexistence of two extremely hot pipelines (Injecting Steam and Production pipelines) on the aboveground pipe rack should be designed with extreme care. The higher than normal design temperature of these lines creates considerable lateral and longitudinal movements and heavy loads on the supporting structure and piling. In addition, since both lines contain high pressure mediums, the design engineer shall include a few more parameters than what is normally considered for conventional pipelines. These parameters include; sustain loads, slug forces, natural frequency, mechanical interactions, frictional forces on anchors and guides, and mechanical engagement of supporting components, as well as the effects of these loads on the steel structure-piling and their reaction with the surrounding soil. In addition the design engineer shall be aware of any potential failures associated with these physical and mechanical parameters, the impact and probability rationales and

    Full Text Available The article deals with the questions of designing the foundations for the Oil Pumping Station-2 site of "Kuyumba - Tayshet" trunk oil pipeline. The problems of choice and grounds for technical solutions are considered basing on the results of complex thermotechnical calculations. The construction territory of OPS-2 site of "Kuyumba - Tayshet" trunk oil pipeline is characterized by complex engineering and geocryological conditions: 1 presence of permafrost soil on 80 % of the site area; 2 absence of sufficiently widespread rocky soils under designed buildings and constructions; 3 transition of loamy grounds into yield during thawing. The buildings and facilities are designed on the basis of pile foundation type with high rigid foundation grill. The piles’ diameter is 325 mm and 426 mm, the total length of piles is 9-12 m. The full designed vertical loading, transferred to the pile, is ranging from 10.6 to 50.4 tf. According to the results of the calculations, in order to provide the necessary bearing capacity of piles, securing the perception of transmitted designed loadings, the equivalent temperature of the soil along the side surface of piles ( e should not be higher than -0,5 °C. Taking into account that the soil temperatures on the projected site mainly range from -0.1 to -0.3 °C, in order to lower their temperatures to the calculated values ventilated underground areas are arranged under the buildings and facilities and seasonally active cooling devices (soil thermal stabilizers are installed. Assembly technique and construction of ventilated underground areas with application of soil thermal stabilizers were developed earlier while designing the pipeline system "Zapolyarye - Oil Pumping Station Purpe". For confirmation of the accepted decisions forecasting thermotechnical calculations were performed with the use of a special computer program TermoStab 67-87, which allows simulating the changes of temperature regimes of the permafrost

    The Oil Pollution Act of 1990 (''OPA'') and an even more problematic array of State pollution laws have raised the cost, and risk, of carrying oil into and out of the US. This report, prepared under contract to the US Department of energy's Office of Domestic and International Policy, examines the impact of Federal and State oil spill legislation on the tanker market. It reviews the role of marine transportation in US oil supply, explores the OPA and State oil spill laws, studies reactions to OPA in the tanker and tank barge industries and in related industries such as insurance and ship finance, and finally, discusses the likely developments in the years ahead. US waterborne oil imports amounted to 6.5 million B/D in 1991, three-quarters of which was crude oil. Imports will rise by almost 3 million B/D by 2000 according to US Department of energy forecasts, with most of the crude oil growth after 1995. Tanker demand will grow even faster: most of the US imports and the increased traffic to other world consuming regions will be on long-haul trades. Both the number of US port calls by tankers and the volume of offshore lightering will grow. Every aspect of the tanker industry's behavior is affected by OPA and a variety of State pollution laws

    The purpose of the study was to assess the biocorrosive activity of oil pipeline soil in the Khanty-Mansiysk Autonomous Region of Yugra and the Krasnodar Territory of the Russian Federation, due to the action of a complex of factors and analysis of sulfate-reducing and thionic bacteria content. The number of bacteria in the sulfur cycle (autotrophic thionic and sulfate-reducing bacteria), the total concentration of sulfur and iron in soil samples adjacent to the surface of underground pipelines, the specific electrical resistivity of the soil was determined. A criterion for the biocorrosive activity of the soil (CBA) was established. The study of the biocorrosive activity of the soil has established its features in the area of the oil pipeline construction in the compared territories. In the soil of the Krasnodar Territory pipeline, aggressive samples were recorded in 5.75% of cases, samples with moderate aggressiveness (49.43%), with weak soil aggressiveness (42.53% of cases), and samples with potential aggressiveness (2.30%). On the territory of the Khanty-Mansiysk Autonomous Region of Yugra, samples with weak soil aggressiveness prevailed (55.17% of cases), with moderate aggressiveness (34.5% of cases). When carrying out multiple regression analysis in the system of variables "factors of soil biocorrosive activity", informative data of modeling the indicator "the content of thiobacteria in soil" was established. The results of the research show the need for dynamic monitoring and the development of preventive measures to prevent biocorrosion.

    Recent national and international emission legislations to reduce emissions of carbon dioxide are forcing power generation industries using coal to look at various alternatives, such as biomass and especially by co-firing techniques. Biomass is transported to the burners either mixed with the primary fuel, in general, coal, or used in dedicated pipelines. In both cases, transportation of biomass is difficult due to its composition, size, shape and physical behaviour in comparison to the transportation of coal. This study considers experimental measurements for biomass particle transportation in a pipeline with a transverse elbow and compares the results with those using computation fluid dynamic (CFD) techniques. Various materials: flour, willow, wood, bark and a mixture of flour and willow, have been considered in the present investigation. The experimental work was performed using the dynamic changes in the electrostatic charges of biomass particles in conjunction with correlation signal processing techniques. The CFD simulations were performed by considering the effects of gravity, non-spherical drag (based on estimated shape factor), detailed information of the particle distribution, particle wall collisions and particle–particle interactions. Good quantitative and qualitative agreement was obtained between the CFD simulations and the experimental data. It is concluded that particle–particle interactions are of less importance if the mass loading ratio of particles to air is less than 0.03. -- Highlights: ► Dispersed biomass particle transportation is studied using experiments and CFD. ► Inclusion of asphericity in the drag model clearly demonstrated the improvements. ► Gravity effects are found to be important for correct particle distribution in pipe lines. ► Inter-particle collisions were less important for mass loading ratios <0.05 kg/kg.

    Oil Sector plays a crucial role in the development of a country and provides the required balance and stability to the economy. Though traditionally coal has had the largest share in the energy basket in India, oil and gas as a source of energy have gradually gained importance and it is expected that oil and gas will continue to command a significant share in the years to come. Transportation of oil and gas by pipelines, which are recognized worldwide as the most reliable and cost effective mode for transportation is a developing business in India. With the increasing demand for oil and gas, a necessity has arisen for according priority attention to develop a well-spread out pipeline network throughout the country so as to facilitate efficient transportation to various consumption centres. The country has already opened its doors to private sector within the country as well as to multinationals. Thus, considerable scope exists not only for making investments but also for consultants, equipment and material manufacturers/suppliers and contractors for providing their services to the Indian pipeline industry. With growth of the economy, the opportunities for investment in the Indian pipeline industry are likely to improve further. (author)

  16. Russia: the pipeline diplomacy

    First world producer of oil and gas, Russia wishes to use its mastery of energy distribution to recover its great power status. The oil and gas pipelines network is the basement used by Russia to build up its hegemony in Europe. The Russian oil and gas companies are also carrying out a long-term strategy of international expansion, in particular thanks to investments in the neighboring countries for the building of new infrastructures or the purchase of oil refineries.

  17. Chevron Texaco wants Kazakh oil to flow through Slovakia

    International Nuclear Information System (INIS)

    Janoska, J.

    2004-01-01

    Chevron Texaco is offering Slovakia an option for the diversification of its oil stocks. It plans to use the Druzba pipeline to transport about 3 million tons of Kazakhstan oil. Most of it should be delivered to the refinery in Czech Kralupy. Pipeline administrator, the company Transpetrol, rejects the proposal and argues that adjusting the pipeline designed for heavy Russian oil to allow the transmission of light oil would cost over SKK 2 billion (Eur 50.04 million). Transpetrol is managed by Russian concern Yukos. Russian oil companies view Caspian oil as competition and the reaction of Transpetrol only follows in line with this attitude. It may sound paradoxical, but letting Caspian oil flow through the Transpetrol pipelines would help Russian concerns expand to Western European markets. The refinery in Kralupy is connected to the IKL pipeline, which connects the Czech Republic to the German network close to the German refinery in Ingolstadt. The one-way pipeline that the Czech used to decrease their dependency on Russian oil and the Druzba pipeline in the nineties would remain unused and discussions about an investment in a change of flow direction to allow the transport of oil to Germany would take on an entirely new dimension. The interest of Chevron may therefore indicate major changes in the European oil distribution network. If the flow direction of the IKL pipeline were to change, it would not only be possible to transport Caspian oil, but also Russian oil. What's more, both US and Western European companies have their sights set on Czech and German refineries that get their oil form the Caspian region and they are also interested in capital entry to Russian oil concerns. This scenario is likely to come true in the case of Yukos

    The degradation problem of petroleum products arises since hydrocarbon acts as an excellent food source for a wide variety of microorganisms. Microbial activity leads to unacceptable level of turbidity, corrosion of pipeline and souring of stored product. The present study emphasizes the role of Bacillus cereus ACE4 on degradation of diesel and its influence on corrosion of API 5LX steel. A demonstrating bacterial strain ACE4 was isolated from corrosion products and 16S rRNA gene sequence analysis showed that it has more than 99% similarity with B. cereus. The biodegradation and corrosion studies revealed that B. cereus degraded the aliphatic protons and aromatic protons in diesel and is capable of oxidizing ferrous/manganese into oxides. This is the first report that discloses the involvement of manganese oxidizer B. cereus ACE4 on biodegradation of diesel and its influence on corrosion in a tropical country pipeline

  2. Consensus Ecological Risk Assessment of Potential Transportation-related Bakken and Dilbit Crude Oil Spills in the Delaware Bay Watershed, USA

    Directory of Open Access Journals (Sweden)

    Ann Hayward Walker

    2016-03-01

    Full Text Available Unconventionally-produced crude oils, i.e., Bakken oil and bitumen diluted for transport and known as dilbit, have become prominent components of the North American petroleum industry. Spills of these oils have occurred during transport from production areas to refineries via pipeline, rail, and barge. Some of their physical and chemical properties are distinct and present new challenges in mitigating spill impacts on people and the environment. This paper describes the adaptation of a qualitative risk assessment process to improve spill preparedness and response decisions for these oils when transported in an estuarine area. The application of this collaborative, interdisciplinary process drew upon a literature review, the local knowledge and experience of a broad set of decision makers, practitioners, and technical experts who developed consensus-based recommendations aimed at improving response to spills of these oils. Two emphasized components of this consensus ecological risk assessment (CERA concerned risks: (1 to human health and safety and (2 from spilled oil and the associated response actions on endangered species. Participants in the process defined levels of concern associated with Bakken and dilbit oils relative to a set of response actions in freshwater, brackish and saltwater habitats and on resources at risk.

    2017-11-01

    In we introduced a novel methodology for efficient transport of heavy oil via a triple layer core-annular flow. Pumping pressures are significantly reduced by concentrating high shear rates to a lubricating layer, while ideas from Visco-Plastic Lubrication are used to eliminate interfacial instabilities. We purposefully position a shaped unyielded skin of a viscoplastic fluid between the transported oil and the lubricating fluid layer to balance the density difference between the fluids. Here we address the sculpting of the shaped skin within a concentric inflow manifold. We use the quasi-steady model to provide inputs to an axisymmetric triple layer computation, showing the development of the streamwise skin profile and establishment of the flow. For this, we use a finite element discretization with the augmented-Lagrangian method to represent the yield surface behaviour accurately and a PLIC method to track the interface motion.

    1982-01-01

    Slurry pipelines have proven to be a technically feasible, environmentally attractive and economic method of transporting finely divided particles over long distances. A pipeline system normally consists of preparation, pipeline and utilization facilities and requires optimization of all three components taken together. A considerable amount of research work has been done to develop hydraulic design of a slurry pipeline. Equipment selection and estimation of corrosion-erosion are considered to be as important as the hydraulic design. Future applications are expected to be for the large-scale transport of coal and for the exploitation of remotely located mineral deposits such as iron ore and copper. Application of slurry pipelines for the exploitation of remotely located mineral deposits is illustrated by the Kudremukh iron concentrate slurry pipeline in India.

    Highlights: → Learning for pipeline construction, if available, is outshadowed by cost variability. → Pipelining is a mature technology, for which much experience has been gained. → Pipeline projects are heterogeneous with widely varying technical and cost specifics. → Pipeline cost components tend to reflect (commodity) market price developments. → Pipeline costs are strongly determined by the properties of the transported gas. -- Abstract: Gases like CH 4 , CO 2 and H 2 may play a key role in establishing a sustainable energy system: CH 4 is the least carbon-intensive fossil energy resource; CO 2 capture and storage can significantly reduce the climate footprint of especially fossil-based electricity generation; and the use of H 2 as energy carrier could enable carbon-free automotive transportation. Yet the construction of large pipeline infrastructures usually constitutes a major and time-consuming undertaking, because of safety and environmental issues, legal and (geo)political siting arguments, technically un-trivial installation processes, and/or high investment cost requirements. In this article we focus on the latter and present an overview of both the total costs and cost components of the distribution of these three gases via pipelines. Possible intricacies and external factors that strongly influence these costs, like the choice of location and terrain, are also included in our analysis. Our distribution cost breakdown estimates are based on transportation data for CH 4 , which we adjust for CO 2 and H 2 in order to account for the specific additional characteristics of these two gases. The overall trend is that pipeline construction is no longer subject to significant cost reductions. For the purpose of designing energy and climate policy we therefore know in principle with reasonable certainty what the minimum distribution cost components of future energy systems are that rely on pipelining these gases. We describe the reasons why we observe

    Controlling the paraffin deposition is one of the most serious and costly problems for high-paraffin crude-oil production and transportation. This holds especially for offshore, deep-water wells and pipelines, like in Vietnam. For finding solutions for these problems, a series of experiments has been performed in order to study the effects of a magnetic field on the rheology of two often produced crude oil samples, using the high and variable magnetic-flux density of a Nd-Fe-B magnet. The resulting changes in the essential characteristics of the magnetically treated (MT) crude oils, like form and size of the paraffin clusters as well as the rheology parameters, have definitely proved the possibility to use a Nd-Fe-B magnetic tool as an environmentally friendly and effective method to control the paraffin deposition in crude oils of Vietnam that have a high paraffin content

    In this work, we investigate the dynamics mechanism of oil transportation in nanochannel using molecular dynamics simulations. It is demonstrated that the interaction between oil molecules and nanochannel has a great effect on the transportation properties of oil in nanochannel. Because of different interactions between oil molecules and channel, the center of mass (COM) displacement of oil in a 6-nm channel is over 30 times larger than that in a 2-nm channel, and the diffusion coefficient of oil molecules at the center of a 6-nm channel is almost two times more than that near the channel surface. Besides, it is found that polarity of oil molecules has the effect on impeding oil transportation, because the electrostatic interaction between polar oil molecules and channel is far larger than that between nonpolar oil molecules and channel. In addition, channel component is found to play an important role in oil transportation in nanochannel, for example, the COM displacement of oil in gold channel is very few due to great interaction between oil and gold substrate. It is also found that nano-sized roughness of channel surface greatly influences the speed and flow pattern of oil. Our findings would contribute to revealing the mechanism of oil transportation in nanochannels and therefore are very important for design of oil extraction in nanochannels.

  12. Slurry pipeline design approach

    2009-12-19

    Compared to other engineering technologies, the design of a commercial long distance Slurry Pipeline design is a relatively new engineering concept which gained more recognition in the mid 1960 's. Slurry pipeline was first introduced to reduce cost in transporting coal to power generating units. Since then this technology has caught-up worldwide to transport other minerals such as limestone, copper, zinc and iron. In South America, the use of pipeline is commonly practiced in the transport of Copper (Chile, Peru and Argentina), Iron (Chile and Brazil), Zinc (Peru) and Bauxite (Brazil). As more mining operations expand and new mine facilities are opened, the design of the long distance slurry pipeline will continuously present a commercially viable option. The intent of this paper is to present the design process and discuss any new techniques and approach used today to ensure a better, safer and economical slurry pipeline. (author)

    Understanding seasonal changes in natural attenuation processes is critical for evaluating source-zone longevity and informing management decisions. The seasonal variations of natural attenuation were investigated through measurements of surficial CO2 effluxes, shallow soil CO2 radiocarbon contents, subsurface gas concentrations, soil temperature, and volumetric water contents during a 2-yr period. Surficial CO2 effluxes varied seasonally, with peak values of total soil respiration (TSR) occurring in the late spring and summer. Efflux and radiocarbon data indicated that the fractional contributions of natural soil respiration (NSR) and contaminant soil respiration (CSR) to TSR varied seasonally. The NSR dominated in the spring and summer, and CSR dominated in the fall and winter. Subsurface gas concentrations also varied seasonally, with peak values of CO2 and CH4 occurring in the fall and winter. Vadose zone temperatures and subsurface CO2 concentrations revealed a correlation between contaminant respiration and temperature. A time lag of 5 to 7 mo between peak subsurface CO2 concentrations and peak surface efflux is consistent with travel-time estimates for subsurface gas migration. Periods of frozen soils coincided with depressed surface CO2 effluxes and elevated CO2 concentrations, pointing to the temporary presence of an ice layer that inhibited gas transport. Quantitative reactive transport simulations demonstrated aspects of the conceptual model developed from field measurements. Overall, results indicated that source-zone natural attenuation (SZNA) rates and gas transport processes varied seasonally and that the average annual SZNA rate estimated from periodic surface efflux measurements is 60% lower than rates determined from measurements during the summer.

    Wax precipitation and deposition is one of the most significant flow assurance challenges in the production system of the crude oil. Wax inhibitors are developed as a preventive strategy to avoid an absolute wax deposition. Wax inhibitors are polymers which can be known as pour point depressants as they impede the wax crystals formation, growth, and deposition. In this study three formulations of wax inhibitors were prepared, ethylene vinyl acetate, ethylene vinyl acetate co-methyl methacrylate (EVA co-MMA) and ethylene vinyl acetate co-diethanolamine (EVA co-DEA) and the comparison of their efficiencies in terms of cloud point¸ pour point, performance inhibition efficiency (%PIE) and viscosity were evaluated. The cloud point and pour point for both EVA and EVA co-MMA were similar, 15°C and 10-5°C, respectively. Whereas, the cloud point and pour point for EVA co-DEA were better, 10°C and 10-5°C respectively. In conclusion, EVA co-DEA had shown the best % PIE (28.42%) which indicates highest percentage reduction of wax deposit as compared to the other two inhibitors.

  16. New reclamation standards for oil and gas well sites and pipelines in the agricultural land reserve

    International Nuclear Information System (INIS)

    Jones, P.

    1995-01-01

    Reclamation standards are a necessity because of increasing density of oil and gas developments, and the number of wells which may be abandoned over the next few years. All petroleum industry users of land are subject to the Agricultural Land Commission Act and require the approval of the Commission. The new General Order 293/95 was discussed, the purpose of which is to streamline existing regulations and to clarify reclamation standards. The new standards are similar to requirements currently in place in northwestern Alberta because landforms, soils, and land there are similar to those that exist in the Peace River region of B.C. Adopting similar requirements also has the added benefit of providing consistency for the industry between adjacent jurisdictions. In essence, the official view is that petroleum developments are temporary activities as long as the land is restored to its original or better condition, and the disruption to farm operations is minimal. Major provisions of General Order 293/95 were reviewed. It was noted that site contamination and the disposal of wastes were not addressed in the General Order. The reason for this is that these matters fall under the jurisdiction of other government agencies. 7 refs

  17. Investigation the Kinetic Models of Biological Removal of Petroleum Contaminated Soil Around Oil Pipeline Using Ryegrass

    Full Text Available The industrial revolution of the past century has resulted in significant damage to environmental resources such as air, water and soil. Petroleum contamination of soil is a serious problem throughout the oil producer countries. Remediation of petroleum contamination of soils is generally a slow and expensive process. Phytoremediation is a potentially less-damaging, cost-effective, but needs longer-term for remediation of contaminated land compared to the alternative methods. In this study the kinetics of petroleum hydrocarbon contaminated soils in Khozestan were investigated. For this paper Ryegrass (Lolium perenne plant selected and the decline of total petroleum hydrocarbon (TPH was analyzed after growth stage, every 10 days up to 90 days. The results of TPH concentration was fitted with zero-order kinetic, first-order kinetic and Higuchi model. The result indicated that degradation of TPH with presence of plants as a function of time was well fitted with the first-order kinetic model. The first-order rate constants (K and half-lives (T1/2 for TPH degradation were 0.0098 1/day and 71 day; respectively. The results of phytoremediation showed that there were 65% decreases in TPH concentration with Ryegrass during the 17 weeks.

    Jones, Jack A.; Chao, Yi

    2011-01-01

    A preliminary study has shown that the use of a high-strength composite fiber cloth material may greatly reduce fabrication and deployment costs of a subsea offshore pipeline. The problem is to develop an inexpensive submerged pipeline that can safely and economically transport large quantities of fresh water, oil, and natural gas underwater for long distances. Above-water pipelines are often not feasible due to safety, cost, and environmental problems, and present, fixed-wall, submerged pipelines are often very expensive. The solution is to have a submerged, compliant-walled tube that when filled, is lighter than the surrounding medium. Some examples include compliant tubes for transporting fresh water under the ocean, for transporting crude oil underneath salt or fresh water, and for transporting high-pressure natural gas from offshore to onshore. In each case, the fluid transported is lighter than its surrounding fluid, and thus the flexible tube will tend to float. The tube should be ballasted to the ocean floor so as to limit the motion of the tube in the horizontal and vertical directions. The tube should be placed below 100-m depth to minimize biofouling and turbulence from surface storms. The tube may also have periodic pumps to maintain flow without over-pressurizing, or it can have a single pump at the beginning. The tube may have periodic valves that allow sections of the tube to be repaired or maintained. Some examples of tube materials that may be particularly suited for these applications are non-porous composite tubes made of high-performance fibers such as Kevlar, Spectra, PBO, Aramid, carbon fibers, or high-strength glass. Above-ground pipes for transporting water, oil, and natural gas have typically been fabricated from fiber-reinforced plastic or from more costly high-strength steel. Also, previous suggested subsea pipeline designs have only included heavy fixed-wall pipes that can be very expensive initially, and can be difficult and expensive

    2005-01-01

    Commercial shippers and regulatory agencies face the challenge of evaluating the merits of various alternative policies for the transportation of crude oil and petroleum products. This paper presented a new risk estimation and assignment methodology that assesses the risk costs for the bodies of water where shipping lanes exist. The methodology is based on historical spills and uses causal data to estimate risk cost between 2 points of reference for numerous products transported by a variety of vessels. In response to public concerns regarding the environmental impacts of accidental spills from tanker ships, laws have been imposed on companies for all costs relating to environmental damage. This measure has prompted the oil industry to take greater responsibility, but a better understanding of tanker re-routing on environmental sensitive areas is needed in order to implement detailed emergency response plans and greater safety precautions. This methodology addressed the need for an efficient maritime transportation system that provides routing for various vessels carrying different petroleum products. The risk estimation methodology successfully modeled a multi-objective, multi-commodity routing problem. 23 refs., 3 figs

    This work develops an optimization structure to aid the operational decision-making of scheduling activities in a real world pipeline network. The proposed approach is based on a decomposition method to address complex problems with high computational burden. The Pre-analysis makes a previous evaluation of a batch sequencing, getting information to be entered into optimization block. The continuous time Mixed Integer Linear Program (MILP) model gets such information and calculates the scheduling. The models are applied to a pipeline network that connects different areas including refineries, terminals, and final clients. Many oil derivatives (e.g. gasoline, liquefied petroleum gas, naphtha) can be sent or received in this network. The computational burden to determine a short-term scheduling within the considered scenario is a relevant issue. Many insights have been derived from the obtained solutions, which are given in a reduced computational time for oil industrial-size scenarios. (author)

  11. Simulating surface oil transport during the Deepwater Horizon oil spill: Experiments with the BioCast system

    Jolliff, Jason Keith; Smith, Travis A.; Ladner, Sherwin; Arnone, Robert A.

    2014-03-01

    The U.S. Naval Research Laboratory (NRL) is developing nowcast/forecast software systems designed to combine satellite ocean color data streams with physical circulation models in order to produce prognostic fields of ocean surface materials. The Deepwater Horizon oil spill in the Gulf of Mexico provided a test case for the Bio-Optical Forecasting (BioCast) system to rapidly combine the latest satellite imagery of the oil slick distribution with surface circulation fields in order to produce oil slick transport scenarios and forecasts. In one such sequence of experiments, MODIS satellite true color images were combined with high-resolution ocean circulation forecasts from the Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS®) to produce 96-h oil transport simulations. These oil forecasts predicted a major oil slick landfall at Grand Isle, Louisiana, USA that was subsequently observed. A key driver of the landfall scenario was the development of a coastal buoyancy current associated with Mississippi River Delta freshwater outflow. In another series of experiments, longer-term regional circulation model results were combined with oil slick source/sink scenarios to simulate the observed containment of surface oil within the Gulf of Mexico. Both sets of experiments underscore the importance of identifying and simulating potential hydrodynamic conduits of surface oil transport. The addition of explicit sources and sinks of surface oil concentrations provides a framework for increasingly complex oil spill modeling efforts that extend beyond horizontal trajectory analysis.

    Pipelining crude oils that contain large proportions of paraffins can cause many specific difficulties. These oils, known as waxy crude oils, usually exhibit high 'pour point', where this temperature is higher than the external temperature conditions surrounding the pipeline. During the shutdown, since the temperature decreases in the pipeline, the gel-like structure builds up and the main difficulty concerns the issue of restarting. This PhD attempts to improve waxy crude oil behaviour understanding thanks to experiment, modelling and numerical simulation in order to predict more accurately time and pressure required to restart the flow. Using various contributions to the literature, waxy crude oils are described as viscoplastic, thixotropic and compressible fluid. Strong temperature history dependence plays a prevailing role in the whole shutdown and restart process. Thus, waxy crude oils under flowing conditions correspond to the non-isothermal flow of a viscoplastic material with temperature-dependent rheological properties. Besides, the restart of a waxy crude oil is simulated by the isothermal transient flow of a weakly compressible thixotropic fluid in axisymmetric pipe geometry. We retain the Houska model to describe the thixotropic/viscoplastic feature of the fluid and compressibility is introduced in the continuity equation. The viscoplastic constitutive equation is involved using an augmented Lagrangian method and the resulting equivalent saddle-point problem is solved thanks to an Uzawa-like algorithm. Governing equations are discretized using a Finite Volume method and the convection terms are treated thanks to a TVD (Total Variation Diminishing) scheme. The Lagrangian functional technique usually used for incompressible viscoplastic flows, is adapted to compressible situations. Several numerical results attest the good convergence properties of the proposed transient algorithm. The non-isothermal results highlight the strong sensitivity of

    2014-12-01

    Full Text Available Three commercially available intercooled compression strategies for compressing CO2 were studied. All of the compression concepts required a final delivery pressure of 153 bar at the inlet to the pipeline. Then, simulations were used to determine the maximum safe pipeline distance to subsequent booster stations as a function of inlet pressure, environmental temperature, thickness of the thermal insulation and ground level heat flux conditions. The results show that subcooled liquid transport increases energy efficiency and minimises the cost of CO2 transport over long distances under heat transfer conditions. The study also found that the thermal insulation layer should not be laid on the external surface of the pipe in atmospheric conditions in Poland. The most important problems from the environmental protection point of view are rigorous and robust hazard identification which indirectly affects CO2 transportation. This paper analyses ways of reducing transport risk by means of safety valves.

  16. Hydrogeological considerations in northern pipeline development. [Permafrost affected by hot or chilled pipeline

    Energy Technology Data Exchange (ETDEWEB)

    Harlan, R L

    1974-11-01

    Some of the hydrogeological implications of construction and operation of oil and gas pipelines in northern regions of Canada are considered in relation to their potential environmental impacts and those factors affecting the security of the pipeline itself. Although the extent to which water in permafrost participates in the subsurface flow regime has not been fully demonstrated, the role of liquid as well as vapor transport in frozen earth materials can be shown from theory to be highly significant; water movement rates in frozen soil are on the same order as those in unsaturated, unfrozen soil. Below 0/sup 0/C, the unfrozen water content in a fine-grained porous medium is dependent on temperature but independent of the total water content. The thermal gradient controls the rate and direction of water movement in permafrost. The groundwater stabilizes the streamflow and in the absence of large lakes provides the main source of flow during the winter. As groundwater is frequently confined by the permafrost, degradation of the permafrost can have significant consequences. The thaw bulb formed around a hot oil pipeline can induce liquefactioned flow of the thawed material. A chilled pipeline could restrict groundwater movement, resulting in buildup of artesian conditions and icings. The liberation and absorption of latent heat on freezing and thawing affects the thermal regime in the ground surface. Recommendations are given for pipeline construction and areas for further study pointed out. (DLC)

    Real-time monitoring and control of complex and large-scale oil pipeline networks is complicated by several requirements, among them: reliability of data acquisition and communication systems; strict time limits between data acquisition and decision of control action; operational constraints of a large number of pipeline devices and multi-objective control, involving economic, operational, environmental and institutional objectives and constraints. The MDTP system was designed for meeting such requirements. A simulation-optimization approach is the strategy adopted for the network state prediction and control. The simulation module is based on the quasi-steady state hydraulics of oil-water flow. The control is centered on the pumping systems, respecting operational constraints of tanks and pipes, without reducing the oil production targets. For real-time control, an optimization scheme generates multiple operational scenarios, the optimum of them being selected by means of a meta-heuristics approach. To meet the strict time limits for deciding the control strategy, a grid computing architecture was adopted, instead of conventional dedicated high-performance computers. (author)

  3. Pipeline Bending Strain Measurement and Compensation Technology Based on Wavelet Neural Network

    Directory of Open Access Journals (Sweden)

    Rui Li

    2016-01-01

    Full Text Available The bending strain of long distance oil and gas pipelines may lead to instability of the pipeline and failure of materials, which seriously deteriorates the transportation security of oil and gas. To locate the position of the bending strain for maintenance, an Inertial Measurement Unit (IMU is usually adopted in a Pipeline Inspection Gauge (PIG. The attitude data of the IMU is usually acquired to calculate the bending strain in the pipe. However, because of the vibrations in the pipeline and other system noises, the resulting bending strain calculations may be incorrect. To improve the measurement precision, a method, based on wavelet neural network, was proposed. To test the proposed method experimentally, a PIG with the proposed method is used to detect a straight pipeline. It can be obtained that the proposed method has a better repeatability and convergence than the original method. Furthermore, the new method is more accurate than the original method and the accuracy of bending strain is raised by about 23% compared to original method. This paper provides a novel method for precisely inspecting bending strain of long distance oil and gas pipelines and lays a foundation for improving the precision of inspection of bending strain of long distance oil and gas pipelines.

  4. The case history of the first pipeline installed in the Arctic and subsequent developments

    Large reserves of gas and oil have been discovered in Arctic areas which have led various companies to initiate research and development in ways to produce and transport these resources to market. The primary mode of transportation is by pipelines. The main problem is that these areas are remote and transportation systems are long and expensive, especially when considering conventional methods of pipeline construction. The reserves in Canada's Arctic areas are large but, at this time, gas cannot be delivered to market at prices competitive with other gas supplies being completed. This, however, is changing as gas and oil reserves in the lower Arctic have increased, and the combining of a transportation system for both, improves the economics for their development. This paper discusses some of the initial works which have been completed to the stage of an actual pipeline installation, and the planned techniques envisioned for future field developments and for long distance transmission systems

    The role of nondestructive evaluation (NDE) of materials used in H pipelines and storage facilities is examined. NDE techniques are available which detect critical flaws in today's natural gas lines, and which should have some success in hydrogen lines made of resistant materials. However, the critical flaws in a hydrogen line which is built of a steel whose toughness is significantly reduced in hydrogen, or which contains low-toughness defects such as weld hard spots, would be extremely difficult to detect with today's instrumentation. That instrumentation is designed to test efficiently long lengths of line with minimum disruption of service. Technology is available that would be capable of the more detailed inspection required for the smaller defects. However, the equipment might be expensive and time-consuming to operate, and these costs must be included in the overall assessment of a system using existing lines without embrittlement protection. In addition, it is evident that strong motivation exists to construct new facilities from steels with improved resistance to hydrogen

    In this work, two investment projects that are characteristic of the recent phase of the Brazilian natural gas industry were economically valued, taking into account the government going Thermoelectric Priority Program or PPT: economical design of a gas pipeline, to be built and operated by a Proprietary Carrier, where the interest variable is the transport tariff that will remunerate the investment and pipeline expansion through compressor stations, sponsored by the only shipper in the system, as it aims at selling gas to a thermoelectric plant, where the interest variable is the net present value of the project. In both cases, some sensitive analyses of the interest variable to variables that carry greater uncertainty are presented. Results show that pipeline expansion is viable. (author)

  8. The cost of pipelining climate change mitigation. An overview of the economics of CH4, CO2 and H2 transportation

    Gases like CH4, CO2 and H2 may play a key role in establishing a sustainable energy system: CH4 is the least carbon-intensive fossil energy resource; CO2 capture and storage can significantly reduce the climate footprint of especially fossil-based electricity generation; and the use of H2 as energy carrier could enable carbon-free automotive transportation. Yet the construction of large pipeline infrastructures usually constitutes a major and time-consuming undertaking, because of safety and environmental issues, legal and (geo)political siting arguments, technically untrivial installation processes, and/or high investment cost requirements. In this article we focus on the latter and present an overview of both the total costs and cost components of the distribution of these three gases via pipelines. Possible intricacies and external factors that strongly influence these costs, like the choice of location and terrain, are also included in our analysis. Our distribution cost breakdown estimates are based on transportation data for CH4, which we adjust for CO2 and H2 in order to account for the specific additional characteristics of these two gases. The overall trend is that pipeline construction is no longer subject to significant cost reductions. For the purpose of designing energy and climate policy we therefore know in principle with reasonable certainty what the minimum distribution cost components of future energy systems are that rely on pipelining these gases. We describe the reasons why we observe limited learning-by-doing and explain why negligible construction cost reductions for future CH4, CO2 and H2 pipeline projects can be expected. Cost data of individual pipeline projects may strongly deviate from the global average because of national or regional effects related to the type of terrain, but also to varying costs of labor and fluctuating market prices of components like steel.

  9. Chaperone turns gatekeeper: PCBP2 and DMT1 form an iron-transport pipeline.

    2014-08-15

    How is cellular iron (Fe) uptake and efflux regulated in mammalian cells? In this issue of the Biochemical Journal, Yanatori et al. report for the first time that a member of the emerging PCBP [poly(rC)-binding protein] Fe-chaperone family, PCBP2, physically interacts with the major Fe importer DMT1 (divalent metal transporter 1) and the Fe exporter FPN1 (ferroportin 1). In both cases, the interaction of the Fe transporter with PCBP2 is Fe-dependent. Interestingly, another PCBP Fe-chaperone, PCBP1, does not appear to bind to DMT1. Strikingly, the PCBP2-DMT1 interaction is required for DMT1-dependent cellular Fe uptake, suggesting that, in addition to functioning as an intracellular Fe chaperone, PCBP2 may be a molecular 'gate- keeper' for transmembrane Fe transport. These new data hint at the possibility that PCBP2 may be a component of a yet-to-be-described Fe-transport metabolon that engages in Fe channelling to and from Fe transporters and intracellular sites.

    Full Text Available Epidemiological studies suggest that consuming diets rich in (extra virgin olive oil is associated with a low incidence of chronic disease, including cardiovascular disease and cancer. Recent evidence has emerged which implicates raised concentrations of plasma triglycerides in the pathogenesis of coronary artery disease (CAD. It has been demonstrated that olive oil contributes to modulate metabolic processes related to secretion and transport of triglycerides. Intestinal triglyceride-rich lipoproteins from olive oil are very efficiently cleared during postprandial metabolism compared to other oils. Then, there is a massive interaction of nascent and remnant triglyceride-rich lipoproteins, as well as lipid metabolites and fat-soluble components, with hepatic and non-hepatic tissues. A diet-related response involves a multitude of gene products, including proteins implicated in lipid synthesis, oxidation and cell differentiation. Particularly, it has been reported a health beneficial effect of several components from (extra virgin olive oil (fatty acids and minor compounds, which are functioning as regulators of gene transcription . This review reaffirm that a diet rich in extra virgin olive oil is of vital importance in the prevention of cardiovascular and other diseases.Estudios epidemiológicos asocian el consumo de una dieta rica en aceite de oliva (virgen extra con una baja incidencia de enfermedades crónicas, como las enfermedades cardiovasculares y el cáncer. Una concentración elevada de triglicéridos en plasma, tanto en ayunas como durante el metabolismo postprandial, está implicada en la patogénesis cardiovascular. Se ha demostrado que el aceite de oliva contribuye a modular los procesos metabólicos relativos a la secreción y al transporte de triglicéridos. Con respecto a otros aceites comestibles, el aceite de oliva genera lipoproteínas intestinales ricas en triglicéridos que se metabolizan con rapidez. En este contexto, se

  13. Hollow-core fiber sensing technique for pipeline leak detection

    Challener, W. A.; Kasten, Matthias A.; Karp, Jason; Choudhury, Niloy

    2018-02-01

    Recently there has been increased interest on the part of federal and state regulators to detect and quantify emissions of methane, an important greenhouse gas, from various parts of the oil and gas infrastructure including well pads and pipelines. Pressure and/or flow anomalies are typically used to detect leaks along natural gas pipelines, but are generally very insensitive and subject to false alarms. We have developed a system to detect and localize methane leaks along gas pipelines that is an order of magnitude more sensitive by combining tunable diode laser spectroscopy (TDLAS) with conventional sensor tube technology. This technique can potentially localize leaks along pipelines up to 100 km lengths with an accuracy of +/-50 m or less. A sensor tube buried along the pipeline with a gas-permeable membrane collects leaking gas during a soak period. The leak plume within the tube is then carried to the nearest sensor node along the tube in a purge cycle. The time-to-detection is used to determine leak location. Multiple sensor nodes are situated along the pipeline to minimize the time to detection, and each node is composed of a short segment of hollow core fiber (HCF) into which leaking gas is transported quickly through a small pressure differential. The HCF sensing node is spliced to standard telecom solid core fiber which transports the laser light for spectroscopy to a remote interrogator. The interrogator is multiplexed across the sensor nodes to minimize equipment cost and complexity.

    At present, the optimization theory and method have been widely used in the optimization scheduling and optimal operation scheme of complex production systems. Based on C++Builder 6 program development platform, the theoretical research results are implemented by computer. The simulation and intelligent decision system of crude oil storage and transportation inventory scheduling are designed. The system includes modules of project management, data management, graphics processing, simulation of oil depot operation scheme. It can realize the optimization of the scheduling scheme of crude oil storage and transportation system. A multi-point temperature measuring system for monitoring the temperature field of floating roof oil storage tank is developed. The results show that by optimizing operating parameters such as tank operating mode and temperature, the total transportation scheduling costs of the storage and transportation system can be reduced by 9.1%. Therefore, this method can realize safe and stable operation of crude oil storage and transportation system.

    2004-07-01

    We present the application of a network transportation model, with capacity restrictions, to determine the minimal cost of supply of a group of markets at the Bolivia Brazil Gas Pipeline influence area, as a function of city gate price. We consider the potential of integration of pipeline transportation at the South Cone, looking forward to supply the Brazilian market. The city gate price consists of the sum of commodity price plus transportation tariffs over every gas pipeline through which the gas passes (except distribution pipelines). There is no distinction related to product quality (e.g. heating value) among suppliers, or among end uses (thermal, thermoelectric or chemical). The model is numerically solved by linear programming. Flow direction alternatives and transportation tariffs alternatives (postal and by zone) are proposed. The model allows, among other applications: identification of the lowest cost supply strategy, identification of network flow capacity bottlenecks, determination of operation and expansion marginal costs using dual solution analysis, investigation of alternative sceneries through sensibility analysis and appreciation of non-optimal solutions that might be attractive.

    2007-09-01

    This report was written to satisfy a milestone of the Enhanced Coal Bed Methane Recovery and CO2 Sequestration task of the Big Sky Carbon Sequestration project. The report begins to assess the costs associated with separating the CO2 from flue gas and then injecting it into an unminable coal seam. The technical challenges and costs associated with CO2 separation from flue gas and transportation of the separated CO2 from the point source to an appropriate sequestration target was analyzed. The report includes the selection of a specific coal-fired power plant for the application of CO2 separation technology. An appropriate CO2 separation technology was identified from existing commercial technologies. The report also includes a process design for the chosen technology tailored to the selected power plant that used to obtain accurate costs of separating the CO2 from the flue gas. In addition, an analysis of the costs for compression and transportation of the CO2 from the point-source to an appropriate coal bed sequestration site was included in the report.

  18. Nord Stream, the German-Russian oil pipeline under the Baltic Sea from the Swedish point of view

    International Nuclear Information System (INIS)

    Crone, Olivier

    2007-01-01

    Nord Stream is a 1.200 km long gas pipeline project between Russia and Germany through the Baltic Sea. It crosses the Swedish, Danish, and Finnish economic zones, and, at mid-way, comprises a control platform about which any traffic will be forbidden within a radius of 500 m. After having recalled some design aspects of this project, the author discusses whether it results in some energetic benefits for Sweden where the project has been a matter of debates on environmental and safety issues. It appears that Sweden is not interested at all in importing fossil energies, and that politicians are opposed to this project, but have no influence on it as the pipeline does not cross Swedish territorial waters. After having evoked the role of Gazprom as energetic weapon of the Russian foreign policy, the author discusses safety issues related to this pipeline and its control platform, and environmental risks as they are perceived by Sweden. Sweden indeed perceives the project infrastructure as being possibly used as a spying tool. As far as environmental issues are concerned, Nord Stream is to submit an environmental impact assessment to Denmark, Finland, Sweden, Germany and Russia. As a Swedish law could constrain and even impede the project, some alternate tracks are already envisaged and studied for the pipeline in order to minimise the environmental impact

    The increasing expansion of the oil and gas industry in Brazil, the current legal requirements relating to security, health and environment in the industrial installations, is necessary that the companies, responsible by the operation of pipelines for oil and gas transport, adopt efficient techniques to assure the operational continuity of these of trustworthy form and insurance. To fulfill this important function it is important that the companies implement a management program to control and register the integrity of the pipelines during the all operational life cycle. Inside of this context of management of the integrity of pipelines, the DNV developed the software ORBIT Pipeline with the intention to serve as an important tool to monitor the technique and security condition of the pipeline, to define the frequency and content technician of the inspection program and to recommend the work of intervention or repair in pipeline when necessary. Additionally to these activities that are carried through directly in the ORBIT Pipeline, also an evaluation of the activity of third part and the land/soil movement is made inside of the systematic for analysis of integrity and risk for onshore pipelines performed by DNV.

    Highlights: • A deceleration system for fuel transportation in a pebble bed reactor is designed. • Dynamic analysis and motion analysis of the deceleration process are conducted. • The effectiveness of the system is verified by the analysis and the experiment. • Some key design parameters are studied to achieve effective deceleration. • This research provides a guide for the design of a pebble bed reactor. - Abstract: The fuel elements cycle occurring inside and outside the core of a pebble bed reactor is carried out by pneumatic conveying. In some processes of conveyance, it is necessary to reduce the velocity of the moving fuel element in a short time to avoid damage to the fuel elements and the equipment. In this research, a deceleration system for near-diameter spheres in pipeline transportation based on the resistance of a pneumatic cushion is designed to achieve an effective and reliable deceleration process. Dynamic analysis and motion analysis of the deceleration process are conducted. The results show that when the fuel element is moving in the deceleration pipeline, the gas in the pipeline is compressed to create a pneumatic cushion which resists the movement of the fuel element. In this way, the velocity of the fuel element is decreased to below the target value. During this process, the deceleration is steady and reliable. On this basis some key design parameters are studied, such as the deceleration pipeline length, the ratio of the diameter of the fuel element to the internal diameter of the pipeline, etc. The experimental results are generally consistent with the analysis and demonstrate the considerable effectiveness of the deceleration process as well. This research provides a guide for the design of the fuel elements cycling system in a pebble bed reactor along with the optimization of its control

  4. Mathematical modelling of oil spill fate and transport in the marine environment incorporating biodegradation kinetics of oil droplets

    Science.gov (United States)

    Spanoudaki, Katerina

    2016-04-01

    Oil biodegradation by native bacteria is one of the most important natural processes that can attenuate the environmental impacts of marine oil spills. However, very few numerical models of oil spill fate and transport include biodegradation kinetics of spilled oil. Furthermore, in models where biodegradation is included amongst the oil transformation processes simulated, it is mostly represented as a first order decay process neglecting the effect of several important parameters that can limit biodegradation rate, such as oil composition and oil droplets-water interface. To this end, the open source numerical model MEDSKIL-II, which simulates oil spill fate and transport in the marine environment, has been modified to include biodegradation kinetics of oil droplets dispersed in the water column. MEDSLIK-II predicts the transport and weathering of oil spills following a Lagrangian approach for the solution of the advection-diffusion equation. Transport is governed by the 3D sea currents and wave field provided by ocean circulation models. In addition to advective and diffusive displacements, the model simulates several physical and chemical processes that transform the oil (evaporation, emulsification, dispersion in the water column, adhesion to coast). The fate algorithms employed in MEDSLIK-II consider the oil as a uniform substance whose properties change as the slick weathers, an approach that can lead to reduced accuracy, especially in the estimation of oil evaporation and biodegradation. Therefore MEDSLIK-II has been modified by adopting the "pseudo-component" approach for simulating weathering processes. Spilled oil is modelled as a relatively small number of discrete, non-interacting components (pseudo-components). Chemicals in the oil mixture are grouped by physical-chemical properties and the resulting pseudo-component behaves as if it were a single substance with characteristics typical of the chemical group. The fate (evaporation, dispersion

    2017-11-01

    Pipelining Liquefied Petroleum Gas (LPG) is a mode of LPG transportation more environmentally-friendly than others due to the lower energy consumption and exhaust emissions. Worldwide, there are over 20000 kilometers of LPG pipelines. There are a number of codes that industry follows for the design, fabrication, construction and operation of liquid LPG pipelines. However, no standards exist to modelling particular critical phenomena which can occur on these lines due to external environmental conditions like the solar radiation pressurization. In fact, the solar radiation can expose above ground pipeline sections at pressure values above the maximum Design Pressure with resulting risks and problems. The present work presents an innovative practice suitable for the Oil & Gas industry to modelling the pressurization induced by the solar radiation on above ground LPG pipeline sections with the application to a real case.

  3. Better US energy policy in pipeline

    Energy Technology Data Exchange (ETDEWEB)

    1979-11-01

    The article points out that criticism from fellow industrialized nations as well as criticism from oil-producing nations is leading America to a steady rationalization of its energy policy. The Carter Administration's decontrol programs which will alter the prices for domestic oil are applauded. Another good sign is the pipeline to transport gas from Alaskan fields, through Canada, directly to major US market areas. Gas is mentioned as the major alternative to oil available to the US and Canada, but there are many environmental issues and pressure groups to contend with before the project can be begun. Carter appointments to the Federal Reserve and the Treasury are viewed as the sound money brigade taking control - namely those who believe that a major stimulant to the growth of inflation is the growth of money stock without an equivalent growth in goods or services. Finally, the symbiotic relationship between America's inflation troubles and its trade deficit is analyzed.

    The aim of this work is to evaluate the reliability of non-destructive test (NDT) techniques for the inspection of pipeline welds employed in the petroleum industry. Radiography, manual and automatic ultrasonic techniques using pulse-echo and time of flight diffraction (TOFD) were employed. Three classes of defects were analyzed: lack of penetration (LP), lack of fusion (LF) and undercut (UC). The tests were carried out on specimen made from pipelines containing defects, which had been artificially inserted on laying the weld bead. The results showed the superiority of the automatic ultrasonic tests for defect detection compared with the manual ultrasonic and radiographic tests. Additionally, artificial neural networks (ANN) were used in the detection and automatic classification of the defects

  5. A hybrid model to predict the entrainment and subsurface transport of oil

    The entrainment of surface oil into the water column and its subsequent subsurface transport and dispersion are predicted by a hybrid analytic-numerical solution to the advective diffusion equation. Total oil or selected hydrocarbon component concentrations in the water column are predicted. Assuming that the principal mechanism for entrainment is due to breaking waves, the oil entrainment rate is specified using the empirically based algorithm of Delvigne and Sweeney (1988). The subsurface transport model explicitly accounts for buoyant forces on dispersed oil by droplet size. Application of the model to an analytic test case and several hypothetical scenarios illustrates the model's utility. 35 refs., 8 figs., 2 tabs

  6. Historical analysis of US pipeline accidents triggered by natural hazards

    Natural hazards, such as earthquakes, floods, landslides, or lightning, can initiate accidents in oil and gas pipelines with potentially major consequences on the population or the environment due to toxic releases, fires and explosions. Accidents of this type are also referred to as Natech events. Many major accidents highlight the risk associated with natural-hazard impact on pipelines transporting dangerous substances. For instance, in the USA in 1994, flooding of the San Jacinto River caused the rupture of 8 and the undermining of 29 pipelines by the floodwaters. About 5.5 million litres of petroleum and related products were spilled into the river and ignited. As a results, 547 people were injured and significant environmental damage occurred. Post-incident analysis is a valuable tool for better understanding the causes, dynamics and impacts of pipeline Natech accidents in support of future accident prevention and mitigation. Therefore, data on onshore hazardous-liquid pipeline accidents collected by the US Pipeline and Hazardous Materials Safety Administration (PHMSA) was analysed. For this purpose, a database-driven incident data analysis system was developed to aid the rapid review and categorization of PHMSA incident reports. Using an automated data-mining process followed by a peer review of the incident records and supported by natural hazard databases and external information sources, the pipeline Natechs were identified. As a by-product of the data-collection process, the database now includes over 800,000 incidents from all causes in industrial and transportation activities, which are automatically classified in the same way as the PHMSA record. This presentation describes the data collection and reviewing steps conducted during the study, provides information on the developed database and data analysis tools, and reports the findings of a statistical analysis of the identified hazardous liquid pipeline incidents in terms of accident dynamics and

    Oil and gas today being developed at different water depth characterized as shallow, deep and ultra-deep waters. Among the major components involved during the offshore installation is pipelines. Pipelines are a transportation method of material through a pipe. In oil and gas industry, pipeline come from a bunch of line pipe that welded together to become a long pipeline and can be divided into two which is gas pipeline and oil pipeline. In order to perform pipeline installation, we need pipe laying barge or pipe laying vessel. However, pipe laying vessel can be divided into two types: S-lay vessel and J-lay vessel. The function of pipe lay vessel is not only to perform pipeline installation. It also performed installation of umbilical or electrical cables. In the simple words, pipe lay vessel is performing the installation of subsea in all the connecting infrastructures. Besides that, the installation processes of pipelines require special focus to make the installation succeed. For instance, the heavy pipelines may exceed the lay vessel’s tension capacities in certain kind of water depth. Pipeline have their own characteristic and we can group it or differentiate it by certain parameters such as grade of material, type of material, size of diameter, size of wall thickness and the strength. For instances, wall thickness parameter studies indicate that if use the higher steel grade of the pipelines will have a significant contribution in pipeline wall thickness reduction. When running the process of pipe lay, water depth is the most critical thing that we need to monitor and concern about because of course we cannot control the water depth but we can control the characteristic of the pipe like apply line pipe that have wall thickness suitable with current water depth in order to avoid failure during the installation. This research will analyse whether the pipeline parameter meet the requirements limit and minimum yield stress. It will overlook to simulate pipe

    2003-01-01

    This conference highlights new developments in refining processes for heavy oil, bitumen, and synthetic crudes. The oil sands/heavy oil industry in Canada has grown significantly in the last decade and could triple by 2012 to reach 2.6 million barrels per day. Experts from the petroleum industry, government organizations and technology providers attended this conference which identified technology gaps and areas where improvements are needed. The presentations demonstrated that many new technologies associated with heavy oil bitumen upgrading and refining have posed compatibility and stability challenges for pipeliners, upgraders and refiners. One of the issues addressed at the conference was the effect of upgrading technologies on market price due to the expected increase in production. Another important issue is how production of bitumen can be increased without significantly increasing greenhouse gas emissions from the refineries and upgrading facilities. The sessions of the conference were entitled: new technology developments in bitumen upgrading; secondary upgrading developments and expanded product opportunities; environmental issues and expanded oil sands development; and, stability and compatibility during the production, transportation and refining of petroleum. Twenty six presentations were indexed separately for inclusion in this database. tabs., figs

    2018-03-01

    This research initiated from the area of oil palm plantations in Indonesia 13 million hectares, triggering consternation of abundance of oil palm trunk when garden regeneration is done. If 4 percent of the area is rehabilitated every year, almost 100 million cubic feet of oil palm will be trash. Biomass in the form of pellets can be processed from oil palm trunk. It is then disseminated back to the palm oil processing area into biomass. The amount of transportation cost of the used ships and trucks was defined as parameters. So the objective function determined the type and number of ship and truck trips that provide the minimum transportation cost. To optimize logistics transportation network in regional port cluster, combining hub-and-spoke transportation system among regional port with consolidation and dispersing transportation systems between ports and their own hinterlands, a nonlinear optimization model for two-stage logistics system in regional port cluster was introduced to simultaneously determine the following factors: the hinterlands serviced by individual ports and transportation capacity operated between each port and its hinterland, cargo transportation volume and corresponding transportation capacity allocated via a hub port from an original port to a destination port, cargo transportation volume and corresponding transportation capacity allocated directly from an original port to a destination port. Finally, a numerical example is given to demonstrate the application of the proposed model. It can be shown that the solution to the proposed non-linear model can be obtained by transforming it into linear programming models.

    It is too early to speculate on where the Transpetrol shares will end up. The bankruptcy trustee of Yukos, Eduard Rebgun, has so far received three offers from Gazprom, the Rusneft oil company and the Penta private equity group via its Cyprian company. All three would like to gain control over the Slovak oil transporting company. As yet, no formal request from the Slovak Republic has been delivered to Moscow. By Trend's deadline, President Ivan Gasparovic and the Minister of Economy, Lubomir Jahnatek, were still negotiating in Moscow with the Russian President, Vladimir Putin. One of the topics on the agenda was the future of the company which transports Russian oil to Europe. Both Slovakia and Russia aim to gain control over the stock and the situation is locked in stalemate The stock in question is owned by the Dutch company, Yukos Finance. And although this company is owned by the bankrupt Yukos, the property rights are in the hands of foundation, Stichting Administratiekantoor Yukos International. Yukos Finance is not in bankruptcy and it is therefore difficult to detach the Yukos shares from the company assets. (authors)

  11. Global offshore pipeline markets

    2001-01-01

    In this article, two experts forecast a recovery in the offshore pipeline market followed by accelerating growth. A number of clearly definable macro trends are affecting the world offshore oil and gas industry and will be of considerable significance to the offshore pipelines industry. The authors' view is of markets that show every chance of enjoying long-term growth prospects driven by the fundamentals of a continuing increase in demand for offshore oil and gas. The offshore industry however has a highly cyclical nature, due to the impact of variations in oil and gas prices and the differing state of maturity of individual regions. Therefore those companies that are able to offer the widest range of pipe types and diameters and methods of installation across the greatest range of geographic markets are likely to prosper most. Thus, this continues to be a market best suited to those able to operate on a global scale and make a corporate commitment measured in decades

    Serious problems were encountered with bears during construction of the 1274-km trans-Alaska oil pipeline between Prudhoe Bay and Valdez. This multi-billion-dollar project traversed both black bear (Ursus americanus Pallas) and grizzly bear (U. arctos L.) habitat throughtout its entire length. Plans for dealing with anticipated problems with bears were often inadequate. Most (71%) problems occurred north of the Yukon River in a previously roadless wilderness where inadequate refuse disposal and widespread animal feeding created dangerous situations. Of the 192 officially reported bear problems associated with the Trans-Alaska Pipeline System (TAPS) (1971-1979), about 65% involved the presence of bears in camps or dumps, 13% the feeding of bears on garbage or handouts, 10% property damage or economic loss, 7% bears under and in buildings, and only 5% charges by bears. Remarkably, no bear-related injuries were reported, suggesting that bears became accustomed to people and did not regard them as a threat. Following construction of the TAPS there have been proposals for pipelines to transport natural gas from Prudhoe Bay to southern and Pacific-rim markets. Based on past experience, some animal control measures were developed during the planning phase for the authorized gas pipeline route in Alaska. Fences installed around 100-person survey camps were found to be effective in deterring bears in two traditionally troublesome areas. 16 refs., 7 figs., 1 tab.

    Currently in the oil industry the logistic chain stands out as a strong candidate to obtain highest profit, since recent studies have pointed out to a cost reduction by adoption of better policies for distribution of oil derivatives, particularly those where pipelines are used to transport products. Although there are models to represent transfers of oil derivatives in pipelines, they are quite complex and computationally burden. In this paper, we are interested on models that are less detailed in terms of fluid dynamics but provide more information about operational decisions in a pipeline network. We propose a discrete event simulation model in ARENA that allows simulating a pipeline network based on average historical data. Time delays for transferring different products can be evaluated through different routes. It is considered that transport operations follow a historical behavior and average time delays can thus be estimated within certain bounds. Due to its stochastic nature, time quantities are characterized by average and dispersion measures. This allows comparing different operational scenarios for product transportation. Simulation results are compared to data obtained from a real world pipeline network and different scenarios of production and demand are analyzed. (author)

    This work investigated effects of three model oil dispersants (Corexit EC9527A, Corexit EC9500A and SPC1000) on settling of fine sediment particles and particle-facilitated distribution and transport of oil components in sediment-seawater systems. All three dispersants enhanced settling of sediment particles. The nonionic surfactants (Tween 80 and Tween 85) play key roles in promoting particle aggregation. Yet, the effects varied with environmental factors (pH, salinity, DOM, and temperature). Strongest dispersant effect was observed at neutral or alkaline pH and in salinity range of 0-3.5wt%. The presence of water accommodated oil and dispersed oil accelerated settling of the particles. Total petroleum hydrocarbons in the sediment phase were increased from 6.9% to 90.1% in the presence of Corexit EC9527A, and from 11.4% to 86.7% for PAHs. The information is useful for understanding roles of oil dispersants in formation of oil-sediment aggregates and in sediment-facilitated transport of oil and PAHs in marine eco-systems.

  17. Multi-dimensional rheology-based two-phase model for sediment transport and applications to sheet flow and pipeline scour

    Sediment transport is fundamentally a two-phase phenomenon involving fluid and sediments; however, many existing numerical models are one-phase approaches, which are unable to capture the complex fluid-particle and inter-particle interactions. In the last decade, two-phase models have gained traction; however, there are still many limitations in these models. For example, several existing two-phase models are confined to one-dimensional problems; in addition, the existing two-dimensional models simulate only the region outside the sand bed. This paper develops a new three-dimensional two-phase model for simulating sediment transport in the sheet flow condition, incorporating recently published rheological characteristics of sediments. The enduring-contact, inertial, and fluid viscosity effects are considered in determining sediment pressure and stresses, enabling the model to be applicable to a wide range of particle Reynolds number. A k − ε turbulence model is adopted to compute the Reynolds stresses. In addition, a novel numerical scheme is proposed, thus avoiding numerical instability caused by high sediment concentration and allowing the sediment dynamics to be computed both within and outside the sand bed. The present model is applied to two classical problems, namely, sheet flow and scour under a pipeline with favorable results. For sheet flow, the computed velocity is consistent with measured data reported in the literature. For pipeline scour, the computed scour rate beneath the pipeline agrees with previous experimental observations. However, the present model is unable to capture vortex shedding; consequently, the sediment deposition behind the pipeline is overestimated. Sensitivity analyses reveal that model parameters associated with turbulence have strong influence on the computed results.

    1992-05-01

    The Oil Pollution Act of 1990 (``OPA``) and an even more problematic array of State pollution laws have raised the cost, and risk, of carrying oil into and out of the US. This report, prepared under contract to the US Department of energy`s Office of Domestic and International Policy, examines the impact of Federal and State oil spill legislation on the tanker market. It reviews the role of marine transportation in US oil supply, explores the OPA and State oil spill laws, studies reactions to OPA in the tanker and tank barge industries and in related industries such as insurance and ship finance, and finally, discusses the likely developments in the years ahead. US waterborne oil imports amounted to 6.5 million B/D in 1991, three-quarters of which was crude oil. Imports will rise by almost 3 million B/D by 2000 according to US Department of energy forecasts, with most of the crude oil growth after 1995. Tanker demand will grow even faster: most of the US imports and the increased traffic to other world consuming regions will be on long-haul trades. Both the number of US port calls by tankers and the volume of offshore lightering will grow. Every aspect of the tanker industry`s behavior is affected by OPA and a variety of State pollution laws.

    1999-01-01

    This report presents the methods and results of calculations performed to predict the critical velocity and pressure drop required for the two-inch pipeline transfer of solid/liquid waste slurry from underground waste storage Tank 241-SY-101 to Tank 241-SY- 102 at the Hanford Site. The effects of temperature and dilution on the critical velocity were included in the analysis. These analyses show that Tank 241-SY-101 slurry should be diluted with water prior to delivery to Tank 241-SY-102. A dilution ratio of 1:1 is desirable and would allow the waste to be delivered at a critical velocity of 1.5 ft/sec. The system will be operated at a flow velocity of 6 ft/sec or greater therefore, this velocity will be sufficient to maintain a stable slurry delivery through the pipeline. The effect of temperature on the critical velocity is not a limiting factor when the slurry is diluted 1:1 with water. Pressure drop at the critical velocity would be approximately two feet for a 125-ft pipeline (or 250-ft equivalent straight pipeline). At 6 ft/sec, the pressure drop would be 20 feet over a 250-ft equivalent straight pipeline

    The E and P activity has a great importance in the oil industry. First, it assesses hydrocarbon reserves that can be recovered in order to provide the highest revenues. Second, it supplies the forecast oil and gas production through adequate lift and transportation methods. These flows become rather difficult and requires high investments for heavy oils, which can be understood as having density larger than 934 kg/m{sup 3} (API grade smaller than about 20) and viscosity higher than 100 cP at reservoir conditions. In this work, the flow of a heavy crude oil and air mixture was made viable by injecting water in the pipe, in order to lubricate the flow and reduce pressure drop, as in the core flow technique. The main objective is to observe the three-phase flow patterns formed in the vertical pipe at different mixture compositions, for application in artificial lift. The oil flow rate was measured through a mass flow meter. Water and gas flow rates were given by rotameters. A high-speed VHS camera (1000 frames/s) attached to the pipeline was used to record the experiments for the determination of the final patterns. These are described and represented in flow maps.

    1995-01-01

    Often oil/gas and other hydrocarbons discovered and produced offshore are transported to onshore facilities via submarine pipelines. The route of such pipelines traverses through coastal/shore approach regions. For a rational/economic design, safe installation and subsequent operation it is of utmost importance to review, evaluate and finalize various environmental hazard such as winds, waves, currents, seabed topography, seabed and sub-bottom soils, seabed erosion and soil accretion. This paper addresses the above described environmental hazards, their assessment and techniques to prepare design parameters which must be used for stability analysis, installation methods, long term operation and maintenance for the shore approaches. Additionally, various proven pipeline installation and stabilization techniques for the shore approach region are detailed. As case histories, three approaches installed in the Dutch North Sea are described

    The system of water injection in XAREU oil production field has an water pipeline sizing 4'' of diameter, between the offshore platform PXA-1 and another PXA-2, that it transfers 165 m{sup 3}/d of salt water for pressurization of the reservoir through the injection well Xareu-23. This water pipeline always presented high degree of corrosion needing frequently installation of cramps to eliminate leakages. After evaluating the costs we conclude that the more attractive it would be the installation of a liner than the launching of a new water pipeline. For the installation of a new water pipeline we would need the approval of IBAMA and of a great number of resources for the substitution of that pipeline. In spite of treating of an unpublished service between two offshore platforms we chose for the installation of a liner, because we had a great technological domain in this service in onshore oil production facilities with many pipelines recovered with this technique. We had to revise all of the procedures so that there was not any surprise to make unfeasible this service. The installation of the system liner, consisted of an internal coating 'in situ' through the insert of plastic tubes(high density polyethylene-HDPE), that it forms a barrier between the pipeline and the transported fluid.

    This work presents a computational tool to assist the operational scheduling of a pipeline network. In this network, transfer of products is carried out by batches, from a source to a destination. This tool implements a proposal to determine priorities of the outgoing batches as well as alternatives for sequencing them fulfilling the stated periods stipulated. This proposal uses an analysis of production and demand plans, stockage, products draining in terminals, as well as operational restrictions of the pipeline network, looking for optimizing the use of resources such as pipes, bombs and tanks. The scenario in study is composed by 14 areas (4 refineries, 2 harbours, 6 distribution centres and 2 costumers) and 29 pipes. Prioritizing the attendance to the areas of source or demand, the algorithm carries choices between routes and possible batches volumes, considering calculations of time windows, that determine the limited interval when transference operations must occur. Moreover, operations called 'lung' are also treated, which involve flow changes during the movement. (author)

  4. Review of the Factors that Influence the Condition of Wax Deposition in Subsea Pipelines

    Directory of Open Access Journals (Sweden)

    Koh Junyi

    2018-03-01

    Full Text Available When crude oil is transported via sub-sea pipeline, the temperature of the pipeline decreases at a deep depth which causes a difference in temperature with the crude oil inside. This causes the crude oil to dissipate its heat to the surrounding until thermal equilibrium is achieved. This is also known as the cloud point where wax begins to precipitate and solidifies at the walls of the pipeline which obstruct the flow of fluid. The main objective of this review is to quantify the factors that influence wax deposition such as temperature difference between the wall of the pipeline and the fluid flowing within, the flow rate of the fluid in the pipeline and residence time of the fluid in the pipeline. It is found the main factor that causes wax deposition in the pipeline is the difference in temperature between the petroleum pipeline and the fluid flowing within. Most Literature deduces that decreasing temperature difference results in lower wax content deposited on the wall of the pipeline. The wax content increases with rising flow rate. As for the residence time, the amount of deposited wax initially increases when residence time increases until it reaches a peak value and gradually decreases. Flow-loop system and cold finger apparatus were used in literature investigations to determine the trends above. Three new models are generated through a regression analysis based on the results from other authors. These new models form a relationship between temperature difference, flow rate, residence time and Reynolds number with wax deposition. These models have high values of R-square and adjusted R-square which demonstrate the reliability of these models.

    Since its invention by M. U. Schoop in the beginning of the 20th century, thermal spray has been used for corrosion protection applications in naval, on-shore, submerged and atmospheric environments. Thermally sprayed coatings of zinc, zinc alloys, aluminum and aluminum alloys are currently the most popular materials used for active corrosion protection of steel and concrete, which can be applied using either of the widely known thermal spray processes of combustion wire or electric arc wire. In the oil and gas exploration and production industry, corrosion protection applications using these technologies have evolved since the early sixties. Thermal spray technology has successfully been used to protect steel-based materials from corrosion in many different fields of application like platforms and pipelines. The most used material in the oil and gas industry is TSA (Thermally Sprayed Aluminum) coating. TSA coatings, with a lifetime of 25 to 30 years, require no maintenance except for cosmetic reasons when painted. The surface temperature of a TSA can go as high as 480 deg C. Although TS (Thermal Spray) is an older process, the number of applications and the number of m{sup 2} it is applied to is still increasing resulting from its maintenance-free and reliable active corrosion-protection features.

  7. Challenges for the heavy oil exportation though pipelines in deep waters; Desafios da exportacao de oleos pesados atraves de oleodutos em aguas profundas

    Due to the high pressures, low temperatures, and high viscosities involved, the heavy oil exportation in deep waters through pipelines imposes a number of challenges to be feasible. The viscosities involved in such scenarios are usually very high, which brings most of the system to a laminar flow even for the higher flow rates. In a laminar flow the viscosity is linearly and directly related to the frictional pressure drop and so its precise determination is crucial for the correct results from simulations in transient or in steady state, including the modeling thermal. This work presents some results in steady state and transient simulations of heavy oil of deg API around 16 and pipe length of approximately 20km. For the analyses in the steady state was concluded that in low outflows the required pressures can surpass the pressures in high outflows. In the transient regimen was concluded that in case of long stop, the return to the full outflow surpasses 6 days and the replacement of the fluids from the pipe by diesel is a solution to reduce significantly this time.

    In the petroleum pipelines flow the objective of the maximum production with the minor cost is desired, considering the techniques, operational and administrative restrictions. One of the biggest difficulties in the pipelines flow is related to increase of viscosity that the fluids produced can present and to the variations during the transport. In this study had been analyzed through computational simulations, using Smart Pumping software, the hydraulic behavior of the network and the operational cost with energy consumption, in function of the variation of the viscosity. Two scenes had been simulated, using a initial kinematic viscosity of 3,029x10{sup -5} m{sup 2}/s, that it was reduced gradually until the minimum limit of 10% of initial viscosity, remaining the too much constant the fluid properties. In scene 1 it was verified that the reduction of viscosity implied in the reduction of the energy cost in up to 14,53%, increase of the daily production in up to 3,88% and the reduction in the cost for m3 flowed off in up to 17,73%, without alterations in the operations. Scene 2 presented similar behavior to scene 1, however, had been necessary interventions to get operations that did not violate the restrictions. The results had ratified the interference of viscosity in the operations and the system petroleum flow costs. (author)

    Since the end of the Sixties, steam-transporting pipelines are given great attention, as pipeline components often fail, partially even long before their designed operation time is over. Thus, experts must increasingly deal with questions of pipelines and their components. Design and calculation, production and operation of pipelines are included in the discussion. Within the frame of this discussion, planners, producers, operators, and technical surveillance personnel must be able to offer a homogenous 'plan for assuring the quality of pipelines' in fossil and nuclear power plants. This book tries to make a contribution to this topic. 'Quality assuring' means efforts made for meeting the demands of quality (reliability). The book does not intend to complete with well-known manuals, as for as a complete covering of the topic is concerned. A substantial part of its sections serves to show how quality assurance of pipelines can be at least partially obtained by surveillance measures beginning with the planning, covering the production, and finally accompanying the operation. There is hardly need to mention that the sort of planning, production, and operation has an important influence on the quality. This is why another part of the sections contain process aspects from the view of the planners, producers, and operators. (orig.) [de

    This presentation focused on four main topics: (1) the existing path of pipelines to eastern Canada, (2) the Chicago hub, (3) transport alternatives, and (4) the Vector Pipeline' expansion plans. In the eastern Canadian market, TransCanada Pipelines dominates 96 per cent of the market share and is effectively immune to expansion costs. Issues regarding the attractiveness of the Chicago hub were addressed. One attractive feature is that the Chicago hub has access to multiple supply basins including western Canada, the Gulf Coast, the mid-continent, and the Rockies. Regarding Vector Pipelines' future plans, the company proposes to construct 343 miles of pipeline from Joliet, Illinois to Dawn, Ontario. Project description included discussion of some of the perceived advantages of this route, namely, extensive storage in Michigan and south-western Ontario, the fact that the proposed pipeline traverses major markets which would mitigate excess capacity concerns, arbitrage opportunities, cost effective expansion capability reducing tolls, and likely lower landed costs in Ontario. Project schedule, costs, rates and tariffs are also discussed. tabs., figs

  13. Reliable pipeline repair system for very large pipe size

    The oil and gas industry worldwide has been mainly depending on the long-term reliability of rigid pipelines to ensure the transportation of hydrocarbons, crude oil, gas, fuel, etc. Many other methods are also utilized onshore and offshore (e.g. flexible lines, FPSO's, etc.), but when it comes to the underwater transportation of very high volumes of oil and gas, the industry commonly uses large size rigid pipelines (i.e. steel pipes). Oil and gas operators learned to depend on the long-lasting integrity of these very large pipelines and many times they forget or disregard that even steel pipelines degrade over time and more often that that, they are also susceptible to various forms of damage (minor or major, environmental or external, etc.). Over the recent years the industry had recognized the need of implementing an 'emergency repair plan' to account for such unforeseen events and the oil and gas operators have become 'smarter' by being 'pro-active' in order to ensure 'flow assurance'. When we consider very large diameter steel pipelines such as 42' and 48' nominal pipe size (NPS), the industry worldwide does not provide 'ready-made', 'off-the-shelf' repair hardware that can be easily shipped to the offshore location and effect a major repair within acceptable time frames and avoid substantial profit losses due to 'down-time' in production. The typical time required to establish a solid repair system for large pipe diameters could be as long as six or more months (depending on the availability of raw materials). This paper will present in detail the Emergency Pipeline Repair Systems (EPRS) that Oceaneering successfully designed, manufactured, tested and provided to two major oil and gas operators, located in two different continents (Gulf of Mexico, U.S.A. and Arabian Gulf, U.A.E.), for two different very large pipe sizes (42'' and 48'' Nominal Pipe Sizes

    The unique difficulties that face oil spill response planning for the oil transportation industry in Alaska were discussed. Three levels of response strategies and actions proposed by the Alaska Petroleum Distributors and Transporters (APD and T) member companies were reviewed. They were: (1) immediate response (on-board resources), (2) in-region response (caches in Subareas), and (3) out-of-region cascaded resources (from Anchorage and other sources). The strategies and levels of capability were proposed as emergency measures in addition to the more important prevention measures already instituted to prevent discharges of non-persistent oil. 5 refs., 2 tabs., 9 figs

    In November 2005, during Hurricane Rita, the tank barge DBL-152 struck a drilling rig that sank, spilling an estimated 3 million gallons of high density, low viscosity oil. A large portion of the oil sank to the sea floor, forming large discrete mats along with smaller globules in other areas, which suggested that long-period wave energy events redistributed the sunken oil. This paper presented details of a study conducted to examine the long-term transport mechanisms of the Louisiana Shelf relating to the spill, as well as potential shoreline and environmental impacts on coastal beaches and nature sanctuaries. An examination of local existing sediments was conducted along with an analysis of wave data and current metre data. Previous spills of relatively heavy oils were compared to the spill, including: Barge Bouchard 155; IXTOC 1 exploratory well; Morris Berman Barge; T/B MCN-5; T/V Alvenus; T/V Berge Banker; and T/V Mobiloil; T/V Sansinena. An examination of the case studies suggested that the oil was expected to remain stationary on the bottom of the sea floor until bottom wave energy generated by storms causes the oil to break up and mix the oil into the water column. It was observed that net transport on the Louisiana-Texas shelf is down-coast and offshore. The oil will remain for a significant period once it is deep enough on the shelf to be infrequently disturbed by storm-induced waves. It was noted that shoreline contacts above background are not anticipated. 12 refs., 6 figs

    This working group provided an update on provincial, federal and industry directions regarding the security of pipeline facilities. The decision to include security issues in the NEB Act was discussed as well as the Pipeline Security Management Assessment Project, which was created to establish a better understanding of existing security management programs as well as to assist the NEB in the development and implementation of security management regulations and initiatives. Amendments to the NEB were also discussed. Areas of pipeline security management assessment include physical safety management; cyber and information security management; and personnel security. Security management regulations were discussed, as well as implementation policies. Details of the Enbridge Liquids Pipelines Security Plan were examined. It was noted that the plan incorporates flexibility for operations and is integrated with Emergency Response and Crisis Management. Asset characterization and vulnerability assessments were discussed, as well as security and terrorist threats. It was noted that corporate security threat assessment and auditing are based on threat information from the United States intelligence community. It was concluded that the oil and gas industry is a leader in security in North America. The Trans Alaska Pipeline Incident was discussed as a reminder of how costly accidents can be. Issues of concern for the future included geographic and climate issues. It was concluded that limited resources are an ongoing concern, and that the regulatory environment is becoming increasingly prescriptive. Other concerns included the threat of not taking international terrorism seriously, and open media reporting of vulnerability of critical assets, including maps. tabs., figs.

    Several fiery rail accidents in 2013-2015 in the U.S. and Canada carrying crude oil produced from the Bakken region of North Dakota have raised questions at many levels on the safety of transporting this, and other types of crude oil, by rail. Sandia National Laboratories was commissioned by the U.S. Department of Energy to investigate the material properties of crude oils, and in particular the so-called "tight oils" like Bakken that comprise the majority of crude oil rail shipments in the U.S. at the current time. The current report is a literature survey of public sources of information on crude oil properties that have some bearing on the likelihood or severity of combustion events that may occur around spills associated with rail transport. The report also contains background information including a review of the notional "tight oil" field operating environment, as well a basic description of crude oils and potential combustion events in rail transport.
