    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.

    Estimates are developed of the energy consumption and energy intensity (EI) of five categories of U.S. pipeline industries: natural gas, crude oil, petroleum products, coal slurry, and water. For comparability with other transportation modes, it is desirable to calculate EI in Btu/Ton-Mile, and this is done, although the necessary unit conversions introduce additional uncertainties. Since water and sewer lines operate by lift and gravity, a comparable EI is not definable.

    1977-11-30

    A qualitative projection (the ''baseline scenario'') is made of the pipeline industry growth to the year 2000. This projection is based on the conventional wisdom of the industry. It is concluded that, to achieve significant growth, the industry must develop the capability, called freight pipeline, to move other commodities than oil and gas, i.e., bulk and packaged goods. Technical and economic performance criteria are identified which, if met by the freight pipeline capability, could induce modal shifts resulting in a reduction of total transportation energy consumption, and would offer other benefits, including compatibility with high-speed rail passenger service.

    This paper describes the experience of TRANSPETRO's Oil Pipelines and Terminals Unit regarding an institutionalized knowledge management (KM) process of systematically promoting technical forums focused on: pipeline and terminal operations; industrial maintenance; and right-of-way activities management. This empirical work adds evidence that in the model of cooperative and communicative knowledge management it is necessary to motivate staff to provide the company with their tacit knowledge and to take a proactive part in knowledge management processes, particularly in technical forums. Within this KM perspective, technical forums have been held by TRANSPETRO for the following purposes: to discuss the main barriers and challenges the oil pipelines and terminals unit has to face in the coming years; to share and disseminate good practices concerning oil pipeline and terminal activities; to discuss new processes, methods and equipment developments with potential application in business and operational processes; to establish action plans concerning the main challenges, barriers and opportunities; to disseminate Research and Development (R and D) projects in course, new procedures, methods and equipment and to promote integration among forum attendees. The two year-experience in TRANSPETRO's Oil Pipelines and Terminals Unit revealed that technical forums have been an important instrument for cooperative and communicative knowledge management, according to evaluations from 173 attendees.

    This paper described the significant impact that meditation can have on a pipeline project and company management in general. It was noted that project managers tend to address organization and mechanical issues in promoting innovation and creativity. As such, the use of meditation is a leading edge concept in advanced management tools. This paper presented a practical and functional meditation approach. The foundation of meditation was described as being a mind-body state where there is alert awareness, sensory inversion, coherence in the brain and deep relaxation that give individual's access to the subconscious mind where the well of creativity is to be found. It was suggested that the use of meditation can be used in the pipeline industry as an effective tool to address soft management issues such as project team stress reduction, enhanced teamwork, increased innovation and improved decision making. It was concluded that as a soft technology, meditation has great potential to become more prominent as progressive industries look for ways to promote creativity and well-being. 14 refs.

    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.

    A project that deploys new technologies need to be confident that the technology can be implemented successfully and will perform reliably as designed. New technology is critical to industry, especially where such technology is a project enable without the existence of a backup solution, but also for projects where such technologies bring potential benefits such as technical, economic, schedule, and environmental improvements. DNV developed and has been implementing for many years a systematic, risk based technology qualification process as described in DNV RP-A203, qualification procedures for new technology. One of the major objectives of a formal technology qualification process is to ensure that risks are properly addressed. The DNV process includes several levels of technology qualification and review, starting with a statement of feasibility and concluding with a Certificate of Fitness for Service. Fluor Corporation (Fluor) has developed a new subsea cryogenic pipe-in-pipe configuration for offshore LNG loading and receiving terminals. The configuration uses a highly efficient thermal nano-porous insulation in the annular space between the inner and outer pipes. This material is kept in an ambient pressure environment, which is produced through sealing by metal bulkheads. The bulkheads transfer the contraction induced axial compression load on the inner cryogenic carrier pipe to the external jacket pipe. The resulting pipeline bundle is a structural element, which addresses the thermal contraction and expansion loads without the use of expansion bellows or ultra-low thermal contraction alloys. Fluor has followed the DNV technology qualification process to achieve the defined milestones therein which culminated in DNV issuing a certificate of fitness for service. Particular focus was put on the new aspects of the design. The certificate of fitness for service for the Fluor subsea LNG pipe technology provides project management with the confidence that this

  16. PIPELINE PRODUCTION LOSSES IN THE NIGERIAN OIL INDUSTRY FROM 1999 TO 2008

    Directory of Open Access Journals (Sweden)

    DR. STELLA MADUEME

    2010-08-01

    Full Text Available This empirical investigation tries to identify the causes and economic costs of pipeline production losses in the Nigerian oil industry from 1999 to 2008. It brings out the total product and value loss within the selected years. It also shows the frequency of occurrence in pipeline incidences as a result of fire outbreak, vandalization and rupture in various areas in Nigeria. Five null hypotheses were formulated to guide the study and time series data data was collected through archival sources and analysed using descriptive and inferential statistics. Data are presented in tables and graphs. Results show that vandalization has been increasing from 1999 to 2008 with its highest incidences at Port Harcourt pipelines. Production losses due to rupture were less frequent though physical product losses were highest between 1999 to 2006. Fire outbreaks were discovered to unfortunately be a yearly event with its highest evidences at Port Harcourt and Warri pipelines. This led to very high wastages and monetary losses over the years. Some of the recommendations are effective protection guideline policies for oil pipelines to avoid product losses through vandalisation and fire out break regular maintenance of oil pipelines to reduce incidences of rupture and increased participation or partnership with communities where pipelines are located for protection.

  17. Federal regulation of the pipeline industry. A summary review. Technical report, Task 2

    1977-05-31

    The principal purposes of this report are to identify the jurisdiction areas of the federal pipeline regulating agencies, and to examine the amenability of the regulatory system to the introduction of energy-conservative new technology into the pipeline industry. The history, scope, and agency structure of state and federal regulation are recounted and some gaps, overlaps, and ambiguities are identified. The only significant inhibitory effects upon technological innovation are found to derive from the FPC and ICC limits upon profit, the 1941 Justice Department consent decree limiting dividends to shipper-owned pipelines, and the income tax rules governing recovery of investment credits and startup losses. Effects of these limits are explored by simulation studies using the Systems, Science and Software pipeline economic model (PEM). Two new concepts of regulation are proposed which would neutralize the inhibitory effect of the present regulatory system and would motivate pipeline operators to conserve energy: one, the use of a national equivalent value in the economic trade-off analyses which justify entry of a technological innovation into the rate base (valuation); and two, a valuation allowance which would reverse the presently often-existing situation and insure that the pipeline operator would realize a greater profit from saving energy than from wasting it.

  18. Hazardous waste management in pipeline terminal: a multi-pronged approach for safe disposal of tank bottom sludge

    2009-12-19

    Indian Oil Corporation Ltd., Pipeline Division owns and operates the 1850 Km long Salaya-Mathura Crude Oil Pipeline (SMPL) with installed capacity of 21 MMTPA. Almost 25 types of crude [90% imported and 10% indigenous] are received into 13 on-shore tanks at Vadinar (the Mother Station of SMPL) through 2 Nos. SPM's anchored in the Arabian Sea and located on the west coast of India in the Gulf of Kutch. Larger quantities of tank bottom sludge that gets generated in the terminal during tank M and I pose serious environmental hazards, as procedures for handling, treatment and disposal of hazardous waste are not well established. With increasingly stringent Environmental norms being enforced by Statutory / Regulatory Authorities, storage of hazardous solid waste in lagoons and its disposal through designated approved agencies within the specified time frame, becomes extremely difficult. This paper seeks to address this issue by putting forth an innovative approach to hazardous waste management in pipeline terminals having large crude oil tank farms that has been adopted at Indian Oil Corporation's Vadinar terminal of SMPL where a multi-pronged approach for safe disposal of tank bottom sludge has been successfully implemented. The terminal has since become a 'Zero sludge location'. (author)

    In order to solve transport problems of industry solid, firstly, a new application notion of pipeline transport was presented, that is to say, combining pretreatment and transport with disposal techniques of industry solid waste. Secondly, the integrated disposal and transport system for industry solid waste was introduced, in particular, the operating principles, equipment set-up, key technology and technical parameters. Next, this paper illustrated the application of this integrated system. Such as it can transport coal sludge with sufficiently high solids content ( about 72%~77%) and high apparent viscosity Generally, the transport distance is about 1 000 m. This system has been successfully used in innocuous disposition and efficient utilization of other industrial byproducts or solid wastes, such as city sludge and paper making waste. The integrated system causes no pollution to the environment for its complete seal and realizes protecting the environment,conserving the energy, promoting the development of cycling economic. Finally, the paper discussed the research works that were needed for studying such pipeline transport system and narrates the relevant condition and application status.

    Two kinds of situations may be distinguished for estimating the operating reliability when maneuvering industrial valves and the probability of undesired events in pipelines and industrial plants: situations in which the risk is identified in repetitive cycles of operations and situations in which there is a permanent hazard due to project configurations introduced by decisions during the engineering design definition stage. The estimation of reliability based on the influence of design options requires the choice of a numerical index, which may include a composite of human operating parameters based on biomechanics and ergonomics data. We first consider the design conditions under which the plant or pipeline operator reliability concepts can be applied when operating industrial valves, and then describe in details the ergonomics and biomechanics risks that would lend itself to engineering design database development and human reliability modeling and assessment. This engineering design database development and reliability modeling is based on a group of engineering design and biomechanics parameters likely to lead to over-exertion forces and working postures, which are themselves associated with the functioning of a particular plant or pipeline. This approach to construct based on ergonomics and biomechanics for a more common industrial valve positioning in the plant layout is proposed through the development of a methodology to assess physical efforts and operator reach, combining various elementary operations situations. These procedures can be combined with the genetic algorithm modeling and four elements of the man-machine systems: the individual, the task, the machinery and the environment. The proposed methodology should be viewed not as competing to traditional reliability and risk assessment bur rather as complementary, since it provides parameters related to physical efforts values for valves operation and workspace design and usability.

    Remote Operated Vehicles are routinely used to undertake inspection and maintenance activities of underwater pipelines in north-west Australia. In doing so, many terabytes of geo-referenced underwater video are collected at depths, and on a scale usually unobtainable for ecological research. We assessed fish diversity and abundance from existing ROV videos collected along 2-3 km sections of two pipelines in north-west Australia, one at 60-80 m water depth and the other at 120-130 m. A total of 5962 individual fish from 92 species and 42 families were observed. Both pipelines were characterised by a high abundance of commercially important fishes including: snappers (Lutjanidae) and groupers (Epinephelidae). The presence of thousands of unidentifiable larval fish, in addition to juveniles, sub-adults and adults suggests that the pipelines may be enhancing, rather than simply attracting, fish stocks. The prevalence and high complexity of sponges on the shallower pipeline and of deepwater corals on the deeper pipeline had a strong positive correlation with the fish abundance. These habitats likely offer a significant food source and refuge for fish, but also for invertebrates upon which fish feed. A greater diversity on the shallower pipeline, and a higher abundance of fishes on both pipelines, were associated with unsupported pipeline sections (spans) and many species appeared to be utilising pipeline spans as refuges. This study is a first look at the potential value of subsea pipelines for fishes on the north-west shelf. While the results suggest that these sections of pipeline appear to offer significant habitat that supports diverse and important commercially fished species, further work, including off-pipeline surveys on the natural seafloor, are required to determine conclusively the ecological value of pipelines and thereby inform discussions regarding the ecological implications of pipeline decommissioning.

    The benzene (C6H6) is a stable hydrocarbon, with pleasant smell, plenty toxic, being able to injure sanguine cells and to cause cancer. It is used as raw materials in the obtainment of several products (inks, waxes, lubricants, etc.), chemicals intermediate and, also, it is found in the petrochemical naphtha and in the gasoline. About 80% of the contaminations for benzene are attributed to the gasoline. In relation to the benzene contents present in the petrochemical processes produced in Brazil, the recent Portaria Interministerial no. 775 (Brazil,2004), of April 28, 2004, prohibits, in whole national territory, the commercialization of finished products that contain benzene in its composition. It is admitted, even so, the presence of this substance as contaminant agent in percentage non superior at 0,8% (in volume), from July 1st, 2004, 0,4% (in volume), from 1st of December of 2005 and 0,1% (in volume), from December 1st, 2007. The Brazilian Ministry of Labour regulation NR-15, P. 776, establish that the companies that produce, transport, store, use or manipulate benzene and its liquid mixtures contends 1% or more of volume, accomplish the registration in the SST - MTE and initiation the Programa de Prevencao de Exposicao Ocupacional ao Benzeno - PPEOB in TRANSPETRO. During the evaluations they had been carried through the recognition of the places, equipment and they had defined the homogeneous groups of exhibition - GHE. From these information, environmental and biological evaluations in the terminals and intermediary stations (TECAM, TEVOL, ESTAP, ESMAN, ESVOL and ESJAP), had been executed, including the accomplishment of essays to determine the presence of benzene in the liquid phase, through the infrared base equipment, GS 1000. With base in the results mitigation and remediation actions were implemented in order to guarantee the occupational health of the components of GHE. (author)

    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.

    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.

    Full Text Available The foreshadowed lockout by Qantas on Saturday, 29 October 2011 of approximately 3000 employees affecting potentially hundreds of thousands of passengers globally, with no warning to the public, sharply focused the public mind on the powers of the Federal industrial tribunal to intervene in industrial disputes. Scenes of stranded passengers, late night Fair Work Australia (FWA hearings and the interventions by Federal and state governments captured the public's attention in ways reminiscent of some of the nation-stopping oil industry disputes of the 1970s and 1980s.Why, people asked, did Qantas have to act so precipitously? Why couldn't the industrial relations system have avoided such a calamity? Trade unions were quick to claim that Qantas had it all planned, which was denied vigorously by Qantas' CEO, Alan Joyce. Federal minister for Workplace Relations, Bill Shorten MP labelled Qantas' decision as a ‘radical over-reaction [with] certainly no warning.’ Approximately one month later, the unions and the Australian Labour Party (ALP would combine at the ALP National Conference to formally respond to the dispute through policy. A plan to investigate whether FWA should be handed greater powers to arbitrate Qantas-type disputes now forms part of the ALP National Policy Agenda.For practitioners and scholars, the Qantas dispute has created an important debate about FWA’s power to arbitrate these kinds of damaging industrial disputes. FWA's swift response to terminate Qantas' intended lockout, in a decision handed down at 2:00 am on the morning on 31 October 2011, invites analysis of the powers of FWA to deal with protracted disputes and the legislative policy drivers at work.The purpose of this article is to do just that, by first providing the context and history of how such disputes were settled by predecessor industrial tribunals. The authors then summarise FWA's current jurisdiction and give a précis of relevant decisions that have been

    During the last two decades we have witnessed great improvements in ICT hardware and software technologies. Three-dimensional content is starting to become commonplace now in many applications. Although for many years 3D technologies have been used in the generation of assets by researchers and experts, nowadays these tools are starting to become commercially available to every citizen. This is especially the case for smartphones, that are powerful enough and sufficiently widespread to perform a huge variety of activities (e.g. paying, calling, communication, photography, navigation, localization, etc.), including just very recently the possibility of running 3D reconstruction pipelines. The REPLICATE project is tackling this particular issue, and it has an ambitious vision to enable ubiquitous 3D creativity via the development of tools for mobile 3D-assets generation on smartphones/tablets. This article presents the REPLICATE project's concept and some of the ongoing activities, with particular attention being paid to advances made in the first year of work. Thus the article focuses on the system architecture definition, selection of optimal frames for 3D cloud reconstruction, automated generation of sparse and dense point clouds, mesh modelling techniques and post-processing actions. Experiments so far were concentrated on indoor objects and some simple heritage artefacts, however, in the long term we will be targeting a larger variety of scenarios and communities.

  13. St. James marine terminal facility description

    Energy Technology Data Exchange (ETDEWEB)

    1993-10-01

    The US Department of Energy (DOE) currently owns and operates a marine terminal on the west bank of the Mississippi River at St. James, Louisiana. The St. James facility was constructed by the Department to provide marine services associated with the fill and drawdown of the Strategic Petroleum Reserve (SPR) crude oil storage facilities located at Bayou Choctaw and Weeks Island, Louisiana. Although strategic to the mission of the SPR in the event of a national emergency, the St. James terminal is situated such that it has a high potential to also serve the commercial industry`s needs for crude oil terminalling and storage. The St. James terminal is located approximately 45 miles west of New Orleans and 30 miles southeast of Baton Rouge, and approximately 160 miles upstream from the mouth of the Mississippi River. Construction of the St. James terminal was initiated in 1978 and was completed in 1980. Since then, the terminal has received and transferred over 125 million barrels of crude oil to the SPR sites for storage. For crude oil distribution, the St. James terminal was connected to the neighboring LOCAP terminal by a 0.1 mile 36-inch pipeline in 1981 and to the Capline terminal by a 0.5 mile 30-inch pipeline in 1988. The terminal also has a 30-inch pipeline connection to the Koch oil terminal which was used for initial fill purposes; however, this pipeline has been disconnected and is currently inactive. A complete description of the St. James terminal facilities, operational capabilities, operational certifications, and future Government requirements are presented in Sections 2, 3, 4, and 5 respectively.

    The chemical constituents within a snowpack can provide information about the atmosphere through which the snow was deposited. Valdez is located in south-central Alaska and has a high-latitude maritime climate, with annual snowfall typically exceeding 8 m within the city limits. Valdez is also the termination point of the trans-Alaska pipeline system, where tankers are loaded with crude oil from the North Slope of Alaska. Integrated samples of the top 1 m of snow were collected at seven sites near Valdez and analyzed for major solutes, lead, and alkylated aromatic compounds, in particular benzene, toluene, ethylbenzene, and xylene (BTEX). For comparison, sites were also sampled near Juneau, Alaska, which has a similar climate but no petroleum transport infrastructure. Major solute chemistry at all sites was dominated by chloride and was consistent with a marine air mass source of ions in precipitation. Sulfate levels in Valdez were typically on the order of 10 {mu}eq l{sup -1} and significantly higher than found in Juneau snow. Other major solute levels were low in Valdez and Juneau. Lead levels were below detection limits for all sites, with the exception of trace concentrations (<0.4 {mu}g l{sup -1}) reported at two Valdez locations. Alkylated organics were present at all Valdez locations, at levels similar to those documented previously in urban locations. No alkylated organics were detected in Juneau snowpacks.

    The transportation of concentrates and tailings through long distance pipeline has been proven in recent years to be the most economic, environmentally friendly and secure means of transporting of mine products. This success has led to an increase in the demand for long distance pipeline throughout the mining industry. In year 2007 alone, a total of over 500 km of pipeline has been installed in South America alone and over 800 km are in the planning stages. As more pipelines are being installed, the need to ensure its operating integrity is ever increasing. Hydrostatic testing of long distance pipeline is one of the most economical and expeditious way to proving the operational integrity of the pipe. The intent of this paper is to show the sound reasoning behind construction hydro testing and the economic benefit it presents. It will show how hydro test pressures are determined based on ASME B31.11 criteria. (author)

    There are two kinds of common cooling modes for unloading system of LNG receiving terminal, the first is directly using the LNG on board, or using the vaporizer to cool down the unloading pipe by vaporizing LNG on ship, and the second is using low-temperature nitrogen to cool down the unloading pipeline to a certain temperature, or using the ship's LNG or directly inputting the liquid. Comparison on the advantages and disadvantages of the two methods is made, and the consumed volume of coolant and cooling time are calculated at different lengths of unloading pipe and sensible heat ratio of 60%, 50%, 40% and 30% of cool insulation pipe. Furthermore, the comparison on the economy of cooling with LNG and liquid nitrogen is carried out. Results show that liquid nitrogen is more economic than that of LNG with half of cost saving, but, the earlier stage investment in LN2 is relatively large.%目前LNG接收站卸料系统的冷却方式有两种,其一是直接采用船上的LNG,使用船上的气化器将LNG气化冷却卸料管路;其二是先使用低温氨气将卸料管路冷却至一定温度后,再采用船上的LNG冷却或直接进液.对比了两种方法的优缺点,计算了不同长度卸料管路和保冷管路显热利用率分别为60%、50%、40%、30%4种情况下,冷却消耗的冷却介质的量和冷却时间,进而比较使用LNG冷却和使用液氮冷却的经济性.结果表明:使用液氮冷却卸料管路比使用LNG冷却卸料管路更经济,费用约可节省一半,但使用液氨冷却前期投资比较大.

    Methods developed by the staff of the Federal Energy Regulatory Commission in cooperation with the natural gas industry to expedite the emergency transfer of natural gas are described. The majority of the United States' natural gas fields are concentrated in the south central region, comprised of Louisiana, Oklahoma, and Texas together with adjacent areas offshore in the Gulf of Mexico. This is the major source area for gas consumed in the northern, northeastern, southeastern, and far western population/industrial centers. The geographic pattern of gas flow through interstate pipelines emanates in gas producing areas and terminates in gas consuming areas. There are many other areas in the United States which produce gas but the amounts are comparatively small compared with Texas, Louisiana, and offshore Louisiana production. The various interconnections associated with a given pipeline for both receipts and deliveries are defined. The maximum volume capability in MMCFD and the volume being delivered in MMCFD are to be considered as estimated volumes. These volumes do not represent absolute volumes that are available but rather volumes for general planning purposes to define the magnitude of each interconnection. If an actual transportation route is desired, a routing may be derived from this report which then must be checked for actual volumes at a particular point in time. It is always possible that at the time of interest, there is no available capacity or deliveries.The data and information are arranged by pipeline company name followed by which companies supply gas to the named pipeline and to which companies the named pipeline delivers gas. Each receipt or delivery location is defined by the county and state.

    Pemex Refinacion and NDT Systems and Services, executed a Total Integrated Maintenance Program of the Process Pipeline System in the Yucatan Peninsula in Mexico, in order to modernize, enhance and bring the pipeline system up to the best industry standards and ensure the integrity, reliability and safe operation of the system. This approach consisted in using multi-diameter ultrasonic inspection technology to determine the current status of the pipelines, repair every 'integrity diminishing' feature present on the system and establish a Certified Maintenance Program to ensure the future reliability and safety of the pipelines. Due to the complex nature of the pipeline construction, dated from 1984, several special modifications, integrations and solutions were necessary to improve the in line inspection survey as for all traditionally unpiggable systems. The Progreso Pipeline System consists in 3 major pipelines which transport diesel, jet fuel and gasoline respectively. The outside diameter of two pipelines varies along its length between 12 inches - 14 inches - 16 inches, making the inspection survey more difficult and particularly demanding an Inspection Tool solution. It is located on the coast of the Yucatan Peninsula, at the Mexican Caribbean, and its main purpose is to transport the product from the docked tanker ships to the Pemex Storage and Distribution Terminal.

    The weakening of Alberta`s regulatory grip on gas pipelines was discussed. Palliser Pipeline Limited has challenged Nova Corp`s monopoly by applying to the National Energy Board (NEB) for permission to build a 150-mile pipeline from Calgary to the Saskatchewan border. If the $350 million project proceeds, it would mean that gas would be flowing out of Alberta for the first time through a line that is not operated by Nova Corp. Palliser would operate with a lower shipping toll, set by the NEB rather than Alberta`s Energy and Utilities Board. Alliance Pipeline Ltd. will also apply to the NEB to build a 1850-mile pipeline that would originate in British Columbia, cross Alberta and terminate in Chicago. Nova Corp has implied that it might have to consider charging distance-based tolls if the Palliser bypass line proceeds. However, Palliser countered that it should not be necessary to change the postage stamp system for that small a fraction. Palliser suggested that Nova was simply reacting because it was facing competition for the first time. Final decision is in the hands of the federal government.

    2008-07-01

    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.

    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.

    2006-07-01

    Although pipelines may be damaged due to natural sources such as stress corrosion cracking (SCC) or hydrogen-induced cracking (HIC), most pipeline damages are a result of third-party interference, such as unauthorized construction in a right of way. Pipelines are also among the prime targets for sabotage because interruptions in energy distribution can render large segments of a population debilitated. The importance of protecting critical infrastructure was emphasized in this theme issue which disseminated information on vulnerability of pipelines due to third-party intrusions, both intentional and unintentional. It summarized the 10 presentations that were delivered at a pipelines security forum in Calgary, Alberta, addressing Canadian and U.S. government and industry approaches to oil and natural gas pipeline security. The opening keynote address remarked on the evolution of international terror networks, the targeting of the energy sector, and the terrorist threat and presence in Canada. Policies towards critical energy infrastructure protection (CIP) were then examined in light of these threats. A policy shift away from traditional defensive protective security towards an offensive intelligence-led strategy to forestall terrorist threats was advocated. Energy sector representatives agreed that Canada needs an effective national lead agency to provide threat assessments, alert notification, and coordination of information pertaining to CIP. It was agreed that early warning information must come from Canadian as well as U.S. sources in order to be pertinent. The conference session on information collection concentrated on defining what sort of threat information is needed by the energy sector, who should collect it and how should it be shared. It was emphasized that government leadership should coordinate threat reporting and disseminate information, set standards, and address the issues of terrorism risk insurance. Concern was raised about the lack of

    The two broad categories of fiber-reinforced composite liner repair and deposited weld metal repair technologies were reviewed and evaluated for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Principal conclusions from a survey of natural gas transmission industry pipeline operators can be summarized in terms of the following performance requirements for internal repair: (1) Use of internal repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling when a new bore must be created to solve a leak or other problem. (3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) The most common size range for 80% to 90% of operators surveyed is 508 mm (20 in.) to 762 mm (30 in.), with 95% using 558.8 mm (22 in.) pipe. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without

    Full Text Available Purpose: The pipeline production is one of major processes in shipbuilding industry. Quality improvement and risk assessment in this process can yield significant savings, both in terms of internal quality costs as well as in terms of customer satisfactions.Design/methodology/approach: Shipbuilding pipeline production quality improvement has been carried out by application of FMEA (Failure Mode and Effect Analysis method. For the successful implementation of FMEA method it is necessary to identify process failure modes or possibility of the appearance of non-compliance, as well as their possible causes. For qualitative analysis of key input variables of the process, in the paper is used Ishikawa diagram and p-chart.Findings: It is shown that proposed approach to risk assessment in shipbuilding pipeline production is applicable to real casa scenario. The analysis has identified the points in the process with the highest probability of occurrence of nonconformities, or the highest risk for error.Research limitations/implications: As the experimenting has been conducted in shipyard, within production process, research schedule must have been set in accordance with production pace. Also, due to character of production process the data collecting was adopted to the production plan in that particular moment.Practical implications: Dealing with causes of potential nonconformities in the process can significantly contribute to the reliability and robustness of the process. Corrective actions that have been taken based on results of analysis significantly contributed to the level of quality in the pipeline production process.Originality/value: The pepper is dealing with a well known method applied in different production environment that are mostly conservative in production approach. It was shown that successful application of proposed approach can yield benefits especially in improved quality of produced pipelines within shipbuilding industry.

    This article presented the views of Nature Quebec regarding the proposed installation of 3 deep water methane terminals in the St. Lawrence Seaway. A review of the proposed projects found that only one of the 3 proposed liquefied natural gas (LNG) terminals would be needed to reduce Quebec's reliance on natural gas coming from Alberta. It was suggested that in order to authorize this project, the advantages and disadvantages of all 3 proposals must be evaluated. In addition, a study should be conducted to determine the impact on local jobs, local economy, the environment and the security of maritime operations associated with the project. It was suggested that a study should review the installation of the associated land and shoreline facilities and their proximity to local residences and commercial institutions that may be affected in the event of a an accident. The infrastructures needed for gas pipeline distribution and rights of passages must also be considered as well as mechanisms to ensure an equitable price distribution between the promoters and the consumers. It was emphasized that although the terminal may be advantageous for Quebec, it is not a necessity. There are currently 68 LNG projects at different stages of implementation across North America. Only a fraction of the projects being constructed are actually needed to meet future energy needs. Nature Quebec does not see any reason to expose residents to environmental or security threats and suggests they demand controls to ensure a useful and safe installation. refs., figs.

    Global software pipelining is a complex but efficient compilation technique to exploit instruction-level parallelism for loops with branches.This paper presents a novel global software pipelining technique,called Trace Software Pipelining,targeted to the instruction-level parallel processors such as Very Long Instruction Word (VLIW) and superscalar machines.Trace software pipelining applies a global code scheduling technique to compact the original loop body.The resulting loop is called a trace software pipelined (TSP) code.The trace softwrae pipelined code can be directly executed with special architectural support or can be transformed into a globally software pipelined loop for the current VLIW and superscalar processors.Thus,exploiting parallelism across all iterations of a loop can be completed through compacting the original loop body with any global code scheduling technique.This makes our new technique very promising in practical compilers.Finally,we also present the preliminary experimental results to support our new approach.

    Pipelines tubes are part of vital mechanical systems largely used in petrochemical industries. They serve to transport natural gases or liquids. They are cylindrical tubes and are submitted to the risks of corrosion due to high PH concentrations of the transported liquids in addition to fatigue cracks due to the alternation of pressure-depression of gas along the time, initiating therefore in the tubes body micro-cracks that can propagate abruptly to lead to failure. The development of the prognostic process for such systems increases largely their performance and their availability, as well decreases the global cost of their missions. Therefore, this paper deals with a new prognostic approach to improve the performance of these pipelines. Only the first mode of crack, that is, the opening mode, is considered.

A technique, which provides accurate and reliable measurement data without interrupting the pipeline operation, ''through the wall'', is the ultrasonic technology. This non-intrusive technology provides data for pig detection as well as it is used for recognising products in pipelines, detecting levels or full/empty states and accomplishment of sediment measurement, distance measurements, position detections and leak search. The article gives a review and describes some applications of ultrasonic technology in pipeline technique. (orig.)

    The ALMA Pipeline is the automated data reduction tool that runs on ALMA data. Current version of the ALMA pipeline produces science quality data products for standard interferometric observing modes up to calibration process. The ALMA Pipeline is comprised of (1) heuristics in the form of Python scripts that select the best processing parameters, and (2) contexts that are given for book-keeping purpose of data processes. The ALMA Pipeline produces a "weblog" that showcases detailed plots for users to judge how each step of calibration processes are treated. The ALMA Interferometric Pipeline was conditionally accepted in March 2014 by processing Cycle 0 and Cycle 1 data sets. From Cycle 2, ALMA Pipeline is used for ALMA data reduction and quality assurance for the projects whose observing modes are supported by the ALMA Pipeline. Pipeline tasks are available based on CASA version 4.2.2, and the first public pipeline release called CASA 4.2.2-pipe has been available since October 2014. One can reduce ALMA data both by CASA tasks as well as by pipeline tasks by using CASA version 4.2.2-pipe.

    The two broad categories of fiber-reinforced composite liner repair and deposited weld metal repair technologies were reviewed and evaluated for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Principal conclusions from a survey of natural gas transmission industry pipeline operators can be summarized in terms of the following performance requirements for internal repair: (1) Use of internal repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling when a new bore must be created to solve a leak or other problem. (3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) The most common size range for 80% to 90% of operators surveyed is 508 mm (20 in.) to 762 mm (30 in.), with 95% using 558.8 mm (22 in.) pipe. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without liners

    The two broad categories of deposited weld metal repair and fiber-reinforced composite liner repair technologies were reviewed for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Preliminary test programs were developed for both deposited weld metal repair and for fiber-reinforced composite liner repair. Evaluation trials have been conducted using a modified fiber-reinforced composite liner provided by RolaTube and pipe sections without liners. All pipe section specimens failed in areas of simulated damage. Pipe sections containing fiber-reinforced composite liners failed at pressures marginally greater than the pipe sections without liners. The next step is to evaluate a liner material with a modulus of elasticity approximately 95% of the modulus of elasticity for steel. Preliminary welding parameters were developed for deposited weld metal repair in preparation of the receipt of Pacific Gas & Electric's internal pipeline welding repair system (that was designed specifically for 559 mm (22 in.) diameter pipe) and the receipt of 559 mm (22 in.) pipe sections from Panhandle Eastern. The next steps are to transfer welding parameters to the PG&E system and to pressure test repaired pipe sections to failure. A survey of pipeline operators was conducted to better understand the needs and performance requirements of the natural gas transmission industry regarding internal repair. Completed surveys contained the following principal conclusions: (1) Use of internal weld repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling (HDD) when a new bore must be created

    Due to the long term usage and irregular maintenance for corrosion checks, catastrophic accidents have been increasing in underground pipelines. In this study, a new safety management methodology of underground pipeline, risk-based pipeline management, is introduced reflecting corrosion effect. First, principle of the risk-based pipeline management is presented compared with an original method, qualitative measure. It is distinguished from the qualitative measure by reflecting societal risk and corrosion in safety management of underground pipeline. And then, it is applied to an existing underground propylene pipeline in Ulsan Industrial Complex, South Korea. The consequence analysis is based on real information, and the frequency analysis reflects degree of corrosion. For calculation of corrosion rate, direct current voltage gradient (DCVG) and close interval potential survey (CIPS) are conducted. As a result of applying the risk-based pipeline management, risk integral is reduced by 56.8% compared to the qualitative measure. Finally, sensitivity analysis is conducted on variables, which affect the risk of the pipeline. This study would contribute to introduce quantitative measure to pipeline management and increase safety of pipeline. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available In Surakarta and its surroundings (Solo Raya, there exists more than 400 Small-Medium Enterprises (SMEs that produce finished products of rattan. Due to the high procurement cost as total operational cost of raw rattan distribution network from the sources, e.g. Borneo and Celebes to the rattan industries, the competitiveness of their products is lower than products from other countries. Therefore, to overcome the problem, those costs should be reduced for example by aggregating the demand of rattan industries. This police needs to be supported by the warehouse for storing and distributing raw rattan. Hence, this research aims to develop a facility location-allocation model so that total supply chain costs, including raw rattan procurement costs as well as facilities opening and closing costs can be minimized. The location-allocation model will be presented in a mixed integer non-linear programming model and solved using MS-Excel Solver. The results are number and location of the warehouse along with the raw rattan allocation in the warehouse to ensure raw rattan supply for rattan industries.

    The mine of Miltonia is located in Paragominas-PA, in the north of Brazil. Bauxite slurry pipeline starts at the Mine of Miltonia and finishes in the draining installation of Alunorte refinery at the port of Barcarena-PA, located approximately 244km away from the mine. The pipeline runs over seven cities and passes below four great rivers stream beds. The system was designed for an underground 24 inches OD steel pipe to carry 9.9 million dry metric tonnes per annum (dMTAs) of 50.5% solid concentration bauxite slurry, using only one pumping station. The system is composed by four storage tanks and six piston diaphragm pumps, supplying a flow of 1680 m3/h. There is a cathodic protection system along the pipeline extension to prevent external corrosion and five pressure monitoring stations to control hydraulic conditions, there is also a fiber optic cable interconnection between pump station and terminal station. Pipeline Systems Incorporated (PSI) was the designer and followed the commissioning program of the start up operations. This paper will describe the beginning of the pipeline operations, technical aspects of the project, the operational experiences acquired in these two years, the faced problems and also the future planning.

    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)

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    In the oil and gas industry, the pipeline is a major component in the transmission and distribution process of oil and gas. Oil and gas distribution process sometimes performed past the pipeline across the various types of environmental conditions. Therefore, in the transmission and distribution process of oil and gas, a pipeline should operate safely so that it does not harm the surrounding environment. Corrosion is still a major cause of failure in some components of the equipment in a production facility. In pipeline systems, corrosion can cause failures in the wall and damage to the pipeline. Therefore it takes care and periodic inspections or checks on the pipeline system. Every production facility in an industry has a level of risk for damage which is a result of the opportunities and consequences of damage caused. The purpose of this research is to analyze the level of risk of 20-inch Natural Gas Transmission Pipeline using Risk-based inspection semi-quantitative based on API 581 associated with the likelihood of failure and the consequences of the failure of a component of the equipment. Then the result is used to determine the next inspection plans. Nine pipeline components were observed, such as a straight pipes inlet, connection tee, and straight pipes outlet. The risk assessment level of the nine pipeline’s components is presented in a risk matrix. The risk level of components is examined at medium risk levels. The failure mechanism that is used in this research is the mechanism of thinning. Based on the results of corrosion rate calculation, remaining pipeline components age can be obtained, so the remaining lifetime of pipeline components are known. The calculation of remaining lifetime obtained and the results vary for each component. Next step is planning the inspection of pipeline components by NDT external methods.

    The integrity assessment of defective pipelines represents a practically important task of structural analysis and design in various technological areas, such as oil and gas industry, power plant engineering and chemical factories. An iterative algorithm is presented for the kinematic limit analysis of 3-D rigid-perfectly plastic bodies. A numerical path scheme for radial loading is adopted to deal with complex multi-loading systems. The numerical procedure has been applied to carry out the plastic collapse analysis of pipelines with part-through slot under internal pressure, bending moment and axial force. The effects of various shapes and sizes of part-through slots on the collapse loads of pipelines are systematically investigated and evaluated. Some typical failure modes corresponding to different configurations of slots and loading forms are studied.

    This paper presents details of an Engineering Critical Assessment (ECA) performed to develop girth weld flaw acceptance criteria for the PETROBRAS Camarupim Pipeline which was installed in Espirito Santo Basin, ES, offshore Brazil in May 2008 by Global Industries. The pipeline was constructed using 24-inch diameter API Grade X65 pipe with wall thicknesses of 0.875-inch (22.2 mm) and 1.00 inch (25.4 mm). Although the Camarupim pipeline will initially transport sweet gas there is the potential for mildly sour service operation in mid to late life. To assess the effect of sour service on the material toughness properties a series of slow strain rate fracture toughness tests were performed in a Project representative sour service environment. In addition the results of sour service fatigue crack growth tests were analyzed to develop a conservative sour service fatigue crack growth law for the ECA analysis. (author)

    In the oil industry, pigging operations in pipelines have been largely applied for different purposes: pipe cleaning, inspection, liquid removal and product separation, among others. An efficient and safe pigging operation requires that a number of operational parameters, such as maximum and minimum pressures in the pipeline and pig velocity, to be well evaluated during the planning stage and maintained within stipulated limits while the operation is accomplished. With the objective of providing an efficient tool to assist in the control and design of pig operations through pipelines, a numerical code was developed, based on a finite difference scheme, which allows the simulation of two fluid transient flow, like liquid-liquid, gas-gas or liquid-gas products in the pipeline. Modules to automatically control process variables were included to employ different strategies to reach an efficient operation. Different test cases were investigated, to corroborate the robustness of the methodology. To validate the methodology, the results obtained with the code were compared with a real liquid displacement operation of a section of the OSPAR oil pipeline, belonging to PETROBRAS, with 30'' diameter and 60 km length, presenting good agreement.

    Two high-quality pipe coatings designed for northern environments were compared for their relative costs and suitability for the conditions that will be encountered in the field. Coating selection should consider local conditions to achieve the optimum life-cycle costs for the system. Some of the key factors affecting the integrity of the protective coating on a pipe include the effects of cold temperature and soil types. In this study, both Fusion Bonded Epoxy (FBE) and High Performance Composite Coatings (HPCC) were evaluated for an entire pipeline installation in a northern environment, from the coating plant to the pipe trench. The evaluation focused on the advantages of better abrasion resistance of the HPCC coating. This was compared against the incremental cost of HPCC coating over FBE on large diameter NPS 30 to NPS 48 pipelines. The following parameters influenced the choice of coating: storage, transportation and handling; bending ability under cold weather conditions; pipe installation and backfilling; weld joint coatings; coating repair and cathodic protection and pipeline integrity. Some of the construction costs that are indirectly affected by the choice of pipe coating include right-of-way preparation and restoration; trenching; supervision, service and downtime and specialist crossings. It was concluded that HPCC has better resistance to abrasion than FBE and is more flexible in extremely cold temperatures. Standard FBE is about 10 per cent less expensive than HPCC. In general HPCC will require less coating protection than FBE, depending on site conditions. 3 refs., 18 tabs., 8 figs.

    As oil and gas production continues to move into new frontier areas, novel applications of the existing riser and pipeline technologies need to be developed to meet the often more stringent requirements encountered in these environments. The challenges include ultra deep water, harsh environments, aggressive fluid conditions, and local content objectives, etc. They will require industry to constantly extend, expand, and enhance the broad range of solution options. Also, the existing design criteria in industry may need to be revised or new criteria may need to be developed to satisfy these needs. Exxon Mobil (Em) employs, and works with others in industry to promote robust design and operating practices. This approach requires in-depth understanding, sound engineering principles, advanced analysis, uncertainty management, and supportive qualification test data. It enables confident selection, extrapolation, and innovation of technologies to address new riser system and pipeline challenges. Focus on fundamental is imperative to ensure integrity of the selected systems during fabrication, installation, and operation phases. Recent and past project experience in deep water Gulf of Mexico and West Africa provides many successful examples of this approach. This paper reviews several examples of the key riser system and pipeline technology enhancements recently achieved by EM to provide confidence in addressing technical and project application challenges. Riser system technology enhancements addressed in this paper include steel catenary riser (SCR) application on turret-moored FPSO with severe motions, pipe-in-pipe (PIP) hybrid production riser to effectively manage gas lift and flow assurance requirements, irregular wave analysis methodology for flexible risers and umbilicals to reduce conservatism, and qualification of riser and pipeline VIV prediction and mitigation methods. Pipeline technology enhancements detailed in this paper include lateral buckling prediction

    2008-07-01

    Twin oil (20 & 24 inch) and gas (20 & 48 inch) pipeline systems stretching 800 km are being constructed to connect offshore hydrocarbon deposits from the Sakhalin II concession in the North to an LNG plant and oil export terminal in the South of Sakhalin island. The onshore pipeline route follows a regional fault zone and crosses individual active faults at 19 locations. Sakhalin Energy, Design and Construction companies took significant care to ensure the integrity of the pipelines, should large seismic induced ground movements occur during the Operational life of the facilities. Complex investigations including the identification of the active faults, their precise location, their particular displacement values and assessment of the fault kinematics were carried out to provide input data for unique design solutions. Lateral and reverse offset displacements of 5.5 and 4.5 m respectively were determined as the single-event values for the design level earthquake (DLE)—the 1000-year return period event. Within the constraints of a pipeline route largely fixed, the underground pipeline fault crossing design was developed to define the optimum routing which would minimize stresses and strain using linepipe materials which had been ordered prior to the completion of detailed design, and to specify requirements for pipe trenching shape, materials, drainage system, etc. Detailed Design was performed with due regard to actual topography and to avoid the possibility of the trenches freezing in winter, the implementation of specific drainage solutions and thermal protection measures.

    This article describes some of the difficulties in constructing an oil pipeline in Colombia across a forested mountain range that has erosion-prone slopes. Engineers are finding ways to protect the pipeline against slope failures and severe erosion problems while contending with threats of guerrilla attacks. Torrential rainfall, precipitous slopes, unstable soils, unfavorable geology and difficult access make construction of an oil pipeline in Colombia a formidable undertaking. Add the threat of guerrilla attacks, and the project takes on a new dimension. In the country's central uplands, a 76 cm pipeline traverses some of the most daunting and formidable terrain in the world. The right-of-way crosses rugged mountains with vertical elevations ranging from 300 m to 2,000 mm above sea level over a distance of some 30 km. The pipeline snakes up and down steep forested inclines in some spots and crosses streams and faults in others, carrying the country's major export--petroleum--from the Cusiana oil field, located in Colombia's lowland interior, to the coast.

    The Common Pipeline Library (CPL) is a set of ISO-C libraries that provide a comprehensive, efficient and robust software toolkit to create automated astronomical data reduction pipelines. Though initially developed as a standardized way to build VLT instrument pipelines, the CPL may be more generally applied to any similar application. The code also provides a variety of general purpose image- and signal-processing functions, making it an excellent framework for the creation of more generic data handling packages. The CPL handles low-level data types (images, tables, matrices, strings, property lists, etc.) and medium-level data access methods (a simple data abstraction layer for FITS files). It also provides table organization and manipulation, keyword/value handling and management, and support for dynamic loading of recipe modules using programs such as EsoRex (ascl:1504.003).

  4. Regulatory reform for natural gas pipelines: The effect on pipeline and distribution company share prices

    Jurman, Elisabeth Antonie

    1997-08-01

    The natural gas shortages in the 1970s focused considerable attention on the federal government's role in altering energy consumption. For the natural gas industry these shortages eventually led to the passage of the Natural Gas Policy Act (NGPA) in 1978 as part of the National Energy Plan. A series of events in the decade of the 1980s has brought about the restructuring of interstate natural gas pipelines which have been transformed by regulators and the courts from monopolies into competitive entities. This transformation also changed their relationship with their downstream customers, the LDCs, who no longer had to deal with pipelines as the only merchants of gas. Regulatory reform made it possible for LDCs to buy directly from producers using the pipelines only for delivery of their purchases. This study tests for the existence of monopoly rents by analyzing the daily returns of natural gas pipeline and utility industry stock price data from 1982 to 1990, a period of regulatory reform for the natural gas industry. The study's main objective is to investigate the degree of empirical support for claims that regulatory reforms increase profits in the affected industry, as the normative theory of regulation expects, or decrease profits, as advocates of the positive theory of regulation believe. I also test Norton's theory of risk which predicts that systematic risk will increase for firms undergoing deregulation. Based on a sample of twelve natural gas pipelines, and 25 utilities an event study concept was employed to measure the impact of regulatory event announcements on daily natural gas pipeline or utility industry stock price data using a market model regression equation. The results of this study provide some evidence that regulatory reforms did not increase the profits of pipeline firms, confirming the expectations of those who claim that excess profits result from regulation and will disappear, once that protection is removed and the firms are operating in

    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)

    Full Text Available In the petroleum, natural gas and petrochemical industries, great attention is being paid to safety, reliability and maintainability of equipment. There are a number of technologies to monitor, control, and maintain gas, oil, water, and sewer pipelines. The paper focuses on operational modal analysis (OMA application for condition monitoring of operating pipelines. Special focus is on the topicality of OMA for definition of the dynamic features of the pipeline (frequencies and mode shapes in operation. The research was conducted using two operating laboratory models imitated a part of the operating pipeline. The results of finite-element modeling, identification of pipe natural modes and its modification under the influence of virtual failure are discussed. The work considers the results of experimental research of dynamic behavior of the operating pipe models using one of OMA techniques and comparing dynamic properties with the modeled data. The study results demonstrate sensitivity of modal shape parameters to modification of operating pipeline technical state. Two strategies of pipeline repair – with continuously condition-based monitoring with proposed technology and without such monitoring, was discussed. Markov chain reliability models for each strategy were analyzed and reliability improvement factor for proposed technology of monitoring in compare with traditional one was evaluated. It is resumed about ability of operating pipeline condition monitoring by measuring dynamic deformations of the operating pipe and OMA techniques application for dynamic properties extraction.

    Offered is a new type of low-cost aerial pipeline for delivery of natural gas, an important industrial and residential fuel, and freshwater as well as other payloads over long distances. The offered pipeline dramatically decreases the construction and operation costs and the time necessary for pipeline construction. A dual-use type of freight pipeline can improve an arid rural environment landscape and provide a reliable energy supply for cities. Our aerial pipeline is a large, self-lofting flexible tube disposed at high altitude. Presently, the term "natural gas" lacks a precise technical definition, but the main components of natural gas are methane, which has a specific weight less than air. A lift force of one cubic meter of methane equals approximately 0.5 kg. The lightweight film flexible pipeline can be located in the Earth-atmosphere at high altitude and poses no threat to airplanes or the local environment. The authors also suggest using lift force of this pipeline in tandem with wing devices for che...

    Optical fibre is deployed widely across the oil and gas industry. As well as being deployed regularly to provide high bandwidth telecommunications and infrastructure for SCADA it is increasingly being used to sense pressure, temperature and strain along buried pipelines, on subsea pipelines and downhole. In this paper we present results from the latest sensing capability using standard optical fibre to detect acoustic signals along the entire length of a pipeline. In Distributed Acoustic Sensing (DAS) an optical fibre is used for both sensing and telemetry. In this paper we present results from the OptaSense{sup TM} system which has been used to detect third party intervention (TPI) along buried pipelines. In a typical deployment the system is connected to an existing standard single-mode fibre, up to 50km in length, and was used to independently listen to the acoustic / seismic activity at every 10 meter interval. We will show that through the use of advanced array processing of the independent, simultaneously sampled channels it is possible to detect and locate activity within the vicinity of the pipeline and through sophisticated acoustic signal processing to obtain the acoustic signature to classify the type of activity. By combining spare fibre capacity in existing buried fibre optic cables; processing and display techniques commonly found in sonar; and state-of-the-art in fibre-optic distributed acoustic sensing, we will describe the new monitoring capabilities that are available to the pipeline operator. Without the expense of retrofitting sensors to the pipeline, this technology can provide a high performance, rapidly deployable and cost effective method of providing gapless and persistent monitoring of a pipeline. We will show how this approach can be used to detect, classify and locate activity such as; third party interference (including activity indicative of illegal hot tapping); real time tracking of pigs; and leak detection. We will also show how an

    1999-01-01

    This project, which began in FY97, involves both the flow loop research on plugging and unplugging of waste transfer pipelines, and the large-scale industrial equipment test of plugging locating and unplugging technologies. In FY98, the related work was performed under the project name ''Mixing, Settling, and Pipe Unplugging of Waste Transfer Lines.'' The mixing, settling, and pipeline plugging and unplugging are critical to the design and maintenance of a waste transfer pipeline system, especially for the High-Level Waste (HLW) pipeline transfer. The major objective of this work is to recreate pipeline plugging conditions for equipment testing of plug locating and removal and to provide systematic operating data for modification of equipment design and enhancement of performance of waste transfer lines used at DOE sites. As the waste tank clean-out and decommissioning program becomes active at the DOE sites, there is an increasing potential that the waste slurry transfer lines will become plugged and unable to transport waste slurry from one tank to another or from the mixing tank to processing facilities. Transfer systems may potentially become plugged if the solids concentration of the material being transferred increases beyond the capability of the prime mover or if upstream mixing is inadequately performed. Plugging can occur due to the solids' settling in either the mixing tank, the pumping system, or the transfer lines. In order to enhance and optimize the slurry's removal and transfer, refined and reliable data on the mixing, sampling, and pipe unplugging systems must be obtained based on both laboratory-scale and simulated in-situ operating conditions.

    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

    Repair logistics is often a challenge in the pipeline industry because of extreme operating conditions. This paper presents an evaluation of the repair logistics at the Urucu-Coari-Manaus gas pipeline in Brazil. This study establishes strategies for each identified failure scenario, classified by type of repair, logistics, resources and costs. Several meetings and brain-storming workshops, bringing together experienced teams from PETROBRAS took place. They provided an analysis of operating conditions for different pipeline sections and an evaluation of the best practices and strategies to be adopted for pipeline repair. Different repair strategies and logistics options were compared with a base case crisis scenario to evaluate gains in terms of repair time reductions. A cost analysis was then done to prioritize these strategies. This study provided important support to the decision making process, with respect to different repair resources and logistics options. It provided formal and innovative solutions.

In order to prevent or effectively manage the impacts of black powder, it is essential to have knowledge of its chemical and physical properties, formation mechanisms and sources. The present paper is divided into three parts. The first part of this paper is a synopsis of published literature. The second part reviews the recent laboratory and field work conducted at Saudi Aramco Research and Development Center to determine the compositions, properties, sources and formation mechanisms of black powder in gas transmission systems. Microhardness, nano-indentation, X-ray Diffraction (XRD), X-ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM) techniques were used to analyze a large number of black powder samples collected from the field. Our findings showed that black powder is generated inside pipelines due to internal corrosion and that the composition of black powder is dependent on the composition of transported gas. The final part presents a summary and brief discussion of various black powder management methods. (author)

    2014-07-01

    Full Text Available The worldwide exploration and development of subsea and deepwater reservoirs has laid down some new and old engineering challenges to the offshore pipeline industry. This requires large D/t pipelines to be installed at water depths in the vicinity of up to 2700m. The deepwater collapse and buckle propagation event is almost unavoidable as the pipe wall thickness cannot be always determined from the codes and standards due to the limit state criteria. These codes also do not consider any fabrication imperfections and sustained damages emanating from transportation and handling. The objective of this paper is to present the Finite Element Analysis (FEA of dented pipes with D/t ratio more than 45, which is outside the applicability of current design codes, and to investigate the effects on installation capacity of these various damage sizes in terms of collapse and buckle propagation.

    A pipeline toolkit was developed to help organizing, reducing and analyzing a large number of near-identical datasets. This is a very general problem, for which many different solutions have been implemented. In this poster we present one such solution that lends itself to users of the Unix command line, using the Unix "make" utility, and adapts itself easily to observational as well as theoretical projects. Two examples are given, one from the CARMA CLASSy survey, and another from a simulated kinematic survey of early galaxy forming disks. The CLASSy survey (discussed in more detail in three accompanying posters) consists of 5 different star forming regions, observed with CARMA, each containing roughly 10-20 datasets in continuum and 3 different molecular lines, that need to be combined in final data cubes and maps. The strength of such a pipeline toolkit shows itself as new data are accumulated, the data reduction steps are improved and easily re-applied to previously taken data. For this we employed a master script that was run nightly, and collaborators submitted improved script and/or pipeline parameters that control these scripts. MIS is freely available for download.

    The Atacama Large Millimeter Array / Atacama Compact Array (ALMA / ACA) Pipeline Heuristics system is being developed to automatically reduce data taken with the standard observing modes such as single fields, mosaics or on-the-fly maps. The goal is to make ALMA user-friendly to astronomers who are not experts in radio interferometry. The Pipeline Heuristics must capture the expert knowledge required to provide data products that can be used without further processing. The Pipeline Heuristics system is being developed as a set of Python scripts using as the data processing engines the Common Astronomy Software Applications (CASA[PY]) libraries and the ATNF Spectral Analysis Package (ASAP). The interferometry heuristics scripts currently provide an end-to-end process for the single field mode comprising flagging, initial calibration, re-flagging, re-calibration, and imaging of the target data. A Java browser provides user-friendly access to the heuristics results. The initial single-dish heuristics scripts implement automatic spectral line detection, baseline fitting and image gridding. The resulting data cubes are analyzed to detect source emission spectrally and spatially in order to calculate signal-to-noise ratios for comparison against the science goals specified by the observer.

    The ALMA (Atacama Large Millimeter Array) Pipeline Heuristics system is being developed to automatically reduce data taken with the standard observing modes. The goal is to make ALMA user-friendly to astronomers who are not experts in radio interferometry. The Pipeline Heuristics system must capture the expert knowledge required to provide data products that can be used without further processing. Observing modes to be processed by the system include single field interferometry, mosaics and single dish `on-the-fly' maps, and combinations of these modes. The data will be produced by the main ALMA array, the ALMA Compact Array (ACA) and single dish antennas. The Pipeline Heuristics system is being developed as a set of Python scripts. For interferometry these use as data processing engines the CASA/AIPS++ libraries and their bindings as CORBA objects within the ALMA Common Software (ACS). Initial development has used VLA and Plateau de Bure data sets to build and test a heuristic script capable of reducing single field data. In this paper we describe the reduction datapath and the algorithms used at each stage. Test results are presented. The path for future development is outlined.

  9. The inverse electroencephalography pipeline

    Weinstein, David Michael

    The inverse electroencephalography (EEG) problem is defined as determining which regions of the brain are active based on remote measurements recorded with scalp EEG electrodes. An accurate solution to this problem would benefit both fundamental neuroscience research and clinical neuroscience applications. However, constructing accurate patient-specific inverse EEG solutions requires complex modeling, simulation, and visualization algorithms, and to date only a few systems have been developed that provide such capabilities. In this dissertation, a computational system for generating and investigating patient-specific inverse EEG solutions is introduced, and the requirements for each stage of this Inverse EEG Pipeline are defined and discussed. While the requirements of many of the stages are satisfied with existing algorithms, others have motivated research into novel modeling and simulation methods. The principal technical results of this work include novel surface-based volume modeling techniques, an efficient construction for the EEG lead field, and the Open Source release of the Inverse EEG Pipeline software for use by the bioelectric field research community. In this work, the Inverse EEG Pipeline is applied to three research problems in neurology: comparing focal and distributed source imaging algorithms; separating measurements into independent activation components for multifocal epilepsy; and localizing the cortical activity that produces the P300 effect in schizophrenia.

    This ammonia pipeline is about 30 km long and links the Fertilizer Plant (FAFEN-BA) to the Urea Marine Terminal (TMU) at the Port of Aratu in Candeias (Bahia State, Brazil). In this study, we characterize the remnants of vegetation and quantify the Permanent Preservation Areas. Furthermore, we propose areas and techniques for their recovery and / or management. The methodology was based on the Rapid Ecological Assessment, which combines selection of areas through remote sensing image analysis, with rapid field campaigns in the selected points. This methodology, successfully applied in PETROBRAS refineries, is first applied in a pipeline influence area. During these campaigns, the main aspects of vegetation, such as phyto physiognomy and ecological succession stages, were registered in field data sheets prepared for this purpose. The most representative remnants of vegetation that could be quantified were Atlantic Forest fragments, as well as those in the Permanent Preservation Areas. (author)

  19. Vortex induced vibrations of free span pipelines

    Energy Technology Data Exchange (ETDEWEB)

    Koushan, Kamran

    2009-07-01

    Pipelines from offshore petroleum fields must frequently pass over areas with uneven sea floor. In such cases the pipeline may have free spans when crossing depressions. Hence, if dynamic loads can occur, the free span may oscillate and time varying stresses may give unacceptable fatigue damage. A major source for dynamic stresses in free span pipelines is vortex induced vibrations (VIV) caused by steady current. This effect is in fact dominating on deep water pipelines since wave induced velocities and accelerations will decay with increasing water depth. The challenge for the industry is then to verify that such spans can sustain the influence from the environment throughout the lifetime of the pipeline. The aim of the present project is to improve the understanding of vortex induced vibrations (VIV) of free span pipelines, and thereby improve methods, existing computer programs and guidelines needed for design verification. This will result in more cost effective and reliable offshore pipelines when laid on a very rugged sea floor. VIV for multiple span pipeline is investigated and the dynamical interaction between adjacent spans has been shown. The interaction may lead to increased or decreased response of each spans depending on the current speed and the properties for the two spans. The extension of the contact zone between the spans and sea floor parameters will of course also be important for the interaction effect. The influence from temperature variation on vortex induced vibrations has been demonstrated. The response frequency is influenced through changes in pipe tension and sag. Both increase and decrease of the response frequency may be experienced. Moreover, it is shown that the influence from snaking of the pipe on the temperature effect is small, at least for large diameter pipes. A free span pipeline will necessarily oscillate close to the seabed. The presence of the seabed will therefore have some influences on the ambient flow profile and also

    1994-05-01

    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.

    Working Group 10 presented experiences acquired from the operation of pipeline systems in a northern environment. There are currently 3 pipelines operating north of 60, notably the Shiha gas pipeline near Fort Liard, the Ikhil gas pipeline in Inuvik and the Norman Wells oil pipeline. Each has its unique commissioning, operating and maintenance challenges, as well as specific training and logistical support requirements for the use of in-line inspection tools and other forms of integrity assessment. The effectiveness of cathodic protection systems in a permafrost northern environment was also discussed. It was noted that the delay of the Mackenzie Gas Pipeline Project by two to three years due to joint regulatory review may lead to resource constraints for the project as well as competition for already scarce human resources. The issue of a potential timing conflict with the Alaskan Pipeline Project was also addressed as well as land use issues for routing of supply roads. Integrity monitoring and assessment issues were outlined with reference to pipe soil interaction monitoring in discontinuous permafrost; south facing denuded slope stability; base lining projects; and reclamation issues. It was noted that automatic welding and inspection will increase productivity, while reducing the need for manual labour. In response to anticipated training needs, companies are planning to involve and train Aboriginal labour and will provide camp living conditions that will attract labour. tabs., figs.

    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.

    Horizontal drilling technology is the single most important enhanced oil recovery technology which has resulted in a significant increase in pipeline utilization. Pipeline operators such as Calgary-based Denim Pipeline Construction Ltd. are responding by using the latest equipment, including excavation equipment, to avoid maintenance delays and downtime. The sales of Denim's horizontal pipe bending equipment have increased due to their attention to worker safety. Denim's horizontal bending machine does not require as much technical support, plus it is faster to install and speeds up production. The machine consists of 3 hydraulic jacks that move on a horizontal plate. Curved dies can be modified to accommodate various diameters of pipe. The bending operation is performed very near to the ground, thereby significantly reducing the risk of pipe injury. Environmental damage is minimized through the use of mechanized mulching which has replaced burning of unwanted trees and brush to clean for pipelines. 1 fig.

    The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by

    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.

    Sloley, A.W. [Process Consulting Services, Inc., Houston, TX (United States)

    1996-09-01

    Both product pipeline operation and terminal blending often generate slops consisting of mixed hydrocarbon streams. Typical slops dispositions include local burning of the fuel for heat or power generation or reshipment to a refinery in a crude stream. Both of these dispositions can incur significant economic penalties. An alternative is the use of a small local plant for the separation of the streams back into pipeline products. This is achievable as long as blend stocks rather then final products containing performance additives are being separated. Final products (gasoline, diesel) contain additives and blending components difficult to handle within the constraints of a small process unit. A proposed multi-product separation unit is presented. The case investigated shows the process configuration required for a unit to process a range of mixtures containing material from LPG to atmospheric gas oil. The material presented includes the plant flow scheme, identification of major equipment, and overall sizing of major equipment. The study results summarize the investment and operating costs of the unit compared to the values of the recoverable products.

    In this paper we present GAIA's findings in three corporate social responsibility projects along pipelines owned by three Brazilian companies in gas, oil and mining sectors. The projects had as the main goal to improve the relationship with communities in the companies' direct influence areas. Clearly, the relationship with communities along pipelines is essential to prevent and reduce industrial hazards. The damage in pipelines due to agriculture, buildings, intentional perforations and traffic of heavy vehicles may cause fatal accidents, environmental and material losses. Such accidents have negative consequences with regard to economy, image and relationship with communities and environmental agencies. From communities' perspective, pipelines deteriorate their life quality due to risk of industrial hazards nearby their houses. The lack of proper information about the pipelines remarkably increases insecurity feelings and discourses against the companies among community leaders. The methodology developed by GAIA comprises companies' and communities' interests and encompasses nine stages. 1. Socio-environmental appraisal or inventory, mapping main risks, communities' needs and their leaders. 2. Communication plan, defining strategies, languages and communication vehicles for each stakeholder group. 3. Inter-institutional meetings to include other institutions in the program. 4. Launching seminar in partnership with local authorities, divulging companies' actions in the cities with pipelines. 5. Multiplier agents formation, enabling teachers, local leaders and government representatives to disseminate correct information about the pipelines such as their functioning, hazard prevention, maintenance actions, and restrictions of activities over the pipelines. 6.

    2015-04-16

    Concepts NREC (CN) has completed a Department of Energy (DOE) sponsored project to analyze, design, and fabricate a pipeline capacity hydrogen compressor. The pipeline compressor is a critical component in the DOE strategy to provide sufficient quantities of hydrogen to support the expected shift in transportation fuels from liquid and natural gas to hydrogen. The hydrogen would be generated by renewable energy (solar, wind, and perhaps even tidal or ocean), and would be electrolyzed from water. The hydrogen would then be transported to the population centers in the U.S., where fuel-cell vehicles are expected to become popular and necessary to relieve dependency on fossil fuels. The specifications for the required pipeline hydrogen compressor indicates a need for a small package that is efficient, less costly, and more reliable than what is available in the form of a multi-cylinder, reciprocating (positive displacement) compressor for compressing hydrogen in the gas industry.

    The National Energy Board (NEB) ensures the safe design, construction and operation of pipelines that cross provincial or national borders. Since 1991, there have been 22 major pipeline failures of which most were closed by corrosion, 5 from stress corrosion cracks, and 3 from slope stability problems. After a meeting of pipeline companies with the NEB, new regulations were put in place. The new regulations include: an emphasis on maintenance, a requirement for proactivity by owners and integrity management guidelines. While the integrity management guidelines are not regulations, they represent industry best practices, allow a degree of flexibility, and allow enforcement based on intent and the use of an audit process. The guidelines are comprised of a management system, a working records management system, condition monitoring, and mitigation.

    2005-03-14

    This report presents the results of an investigation into two methods of using the natural gas pipeline as a communication medium. The work addressed the need to develop secure system monitoring and control techniques between the field and control centers and to robotic devices in the pipeline. In the first method, the pipeline was treated as a microwave waveguide. In the second method, the pipe was treated as a leaky feeder or a multi-ground neutral and the signal was directly injected onto the metal pipe. These methods were tested on existing pipeline loops at UMR and Batelle. The results reported in this report indicate the feasibility of both methods. In addition, a few suitable communication link protocols for this network were analyzed.

  19. Nondestructive characterization of pipeline materials

    Engle, Brady J.; Smart, Lucinda J.; Bond, Leonard J.

    2015-03-01

    There is a growing need to quantitatively and nondestructively evaluate the strength and toughness properties of pipeline steels, particularly in aging pipeline infrastructure. These strength and toughness properties, namely yield strength, tensile strength, transition temperature, and toughness, are essential for determining the safe operating pressure of the pipelines. For some older pipelines crucial information can be unknown, which makes determining the pressure rating difficult. Current inspection techniques address some of these issues, but they are not comprehensive. This paper will briefly discuss current inspection techniques and relevant literature for relating nondestructive measurements to key strength and toughness properties. A project is in progress to provide new in-trench tools that will give strength properties without the need for sample removal and destructive testing. Preliminary experimental ultrasonic methods and measurements will be presented, including velocity, attenuation, and backscatter measurements.

    Since the beginning of the VLT operations in 1998, substantial effort has been put in the development of automatic data reduction tools for the VLT instruments. A VLT instrument pipeline is a complex system that has to be able to identify and classify each produced FITS file, optionally retrieve calibration files from a database, use an image processing software to reduce the data, compute and log quality control parameters, produce FITS images or tables with the correct headers, optionally display them in the control room and send them to the archive. Each instrument has its own dedicated pipeline, based on a common infrastructure and installed with the VLT Data Flow System (DFS). With the increase in the number and the complexity of supported instruments and in the rate of produced data, these pipelines are becoming vital for both the VLT operations and the users, and request more and more resources for development and maintenance. This paper describes the different pipeline tasks with some real examples. It also explains how the development process has been improved to both decrease its cost and increase the pipelines quality using the lessons learned from the first instruments pipelines development.

    a university career at some point in their lives but only 6% of the PhD respondents had applied for the open positions. 69% of Ph.D. students in the survey had graduation dates that would have made them eligible to apply for the open positions. 51% of the responding graduate students are US citizens. Full time graduate student enrollment would have to increase by 75% in order to provide enough graduate students to meet tenure and promotion expectations for mining engineering faculty in the U.S. New research funding on the order of $17M per year would have to be supplied to sustain the mining engineering faculty at a level expected of most R1 engineering colleges. Salaries for new faculty hires are comparable to those offered to BSc graduates by industry. The difficulties in achieving tenure due to lack of government research funding have made academic careers unattractive. If a solution is not found soon to refill the faculty pipeline, the U.S. is in danger of losing nearly all of its capacity to educate students in mining engineering.

    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)

  4. Pipeline bottoming cycle study. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-01

    The technical and economic feasibility of applying bottoming cycles to the prime movers that drive the compressors of natural gas pipelines was studied. These bottoming cycles convert some of the waste heat from the exhaust gas of the prime movers into shaft power and conserve gas. Three typical compressor station sites were selected, each on a different pipeline. Although the prime movers were different, they were similar enough in exhaust gas flow rate and temperature that a single bottoming cycle system could be designed, with some modifications, for all three sites. Preliminary design included selection of the bottoming cycle working fluid, optimization of the cycle, and design of the components, such as turbine, vapor generator and condensers. Installation drawings were made and hardware and installation costs were estimated. The results of the economic assessment of retrofitting bottoming cycle systems on the three selected sites indicated that profitability was strongly dependent upon the site-specific installation costs, how the energy was used and the yearly utilization of the apparatus. The study indicated that the bottoming cycles are a competitive investment alternative for certain applications for the pipeline industry. Bottoming cycles are technically feasible. It was concluded that proper design and operating practices would reduce the environmental and safety hazards to acceptable levels. The amount of gas that could be saved through the year 2000 by the adoption of bottoming cycles for two different supply projections was estimated as from 0.296 trillion ft/sup 3/ for a low supply projection to 0.734 trillion ft/sup 3/ for a high supply projection. The potential market for bottoming cycle equipment for the two supply projections varied from 170 to 500 units of varying size. Finally, a demonstration program plan was developed.

  5. Products pipelines facing major operational changes. Lead phasedown

    Energy Technology Data Exchange (ETDEWEB)

    Teel, H.L.

    1985-06-01

    This paper studies the impact which the US Environmental Protection Agency's new standards for lead in gasoline will have on petroleum products pipelines. The options that refiners may exercise in their approach to lead phasedown are examined. Although most refiners will have little trouble complying with the 0.1 gm/gal standard, the authors express concern in the area of handling gasoline at 0.1 gm/gal if EPA specifies a minimum lead content necessary to protect those engines that require lead. For those pipelines that operate loading terminals, the handling of sub-grades will tax existing facilities. Alcohol storage tanks must be designed to prevent water entry from rain and snow. Additional mainline monitoring will be required. The types of fuels that multi-product pipelines will be asked to handle as a result of lead phasedown is uncertain at this time. But the authors are certain that the products pipeline business is in for challenging, interesting, and perhaps, even revolutionary times.

    The success in developing of the oil industry operating in offshore-onshore terminals, connected by pipelines with the facilities of the coastal zone, can be attributed partially to the beach morpho dynamic monitoring. This study represents a solution to the concerns of the technical operations in coastal zones because it minimizes the impact of the petroleum production and it assures the environmental protection associated to the risks of the pipelines breaking. This impact type results mainly of the vertical and horizontal displacements of the beach, from the coastal dunes to the shore face. The mobility of the profile is associated to the magnitude of the sedimentary processes, which reproduce naturally or not, in scale of time that can vary among few days, years or decades. For the monitoring and interpretation of the beach profile mobility the following methods are recommended: calculation of the closure depth with base in the wave data; bathymetric survey with sled; calculation of the equilibrium beach profile, and monitoring of the variations of the shoreline using satellite images, GPS or aerial photography.

  8. Local scour at submarine pipelines

    Institute of Scientific and Technical Information of China (English)

    Yee-Meng Chiew

    2010-01-01

    The rapid development of offshore oil_fields has increased the number of submarine pipelines being constructed for the transport of crude oil to onshore refineries.Interactions between the pipeline and an erodible bed under the influence of current and waves often lead to local scouring around the structure.When this occurs, the pipeline may be suspended on the seabed resulting in the formation of a span.If the free span is long enough, the pipe may experience resonant flow-induced oscillations,leading to structural failure.This study examines the complex flow-structure-sediment interaction leading to the development of local scour holes around submarine pipelines.It reviews published literature in this area,which primarily is confined to the development of 2-dimensional scour holes.Despite the abundance of such research studies,pipeline-scour in the field essentially is 3-dimensional in nature.Hence, most of these studies have overlooked the importance of the transverse dimension of the scour hole,while emphasizing on its vertical dimension.This dearly is an issue that must be re-examined in light of the potential hazard and environmental disaster that one faces in the event of a pipeline failure.Recent studies have begun to recognize this shortcoming,and attempts have been made to overcome the deficiency.The study presents the state-of-the-art knowledge on local scour at submarine pipelines,both from a 2-dimensional as well as the 3-dimensional perspective.

  9. Optimisation of pipeline route in the presence of obstacles based on a least cost path algorithm and laplacian smoothing

    2017-09-01

    Full Text Available Subsea pipeline route design is a crucial task for the offshore oil and gas industry, and the route selected can significantly affect the success or failure of an offshore project. Thus, it is essential to design pipeline routes to be eco-friendly, economical and safe. Obstacle avoidance is one of the main problems that affect pipeline route selection. In this study, we propose a technique for designing an automatic obstacle avoidance. The Laplacian smoothing algorithm was used to make automatically generated pipeline routes fairer. The algorithms were fast and the method was shown to be effective and easy to use in a simple set of case studies.

    Banks, W. F.

    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.

    The purpose of this analysis is to predict how it can be affected the individual risk and the public's general security due to the operation of a gas pipeline. In case that the single or social risks are considered intolerable, compared with the international standards, to be recommended measures of mitigation of the risk associated to the operation until levels that can be considered compatible with the best practices in the industry. The quantitative risk analysis calculates the probability of occurrence of an event based on the frequency of occurrence of the same one and it requires a complex mathematical treatment. The present work has as objective to develop a calculation methodology based on the previously mentioned publication. This calculation methodology is centered in defining the frequencies of occurrence of events, according to representative database of each case in study. Besides, it settles down the consequences particularly according to the considerations of each area and the different possibilities of interferences with the gas pipeline in study. For each one of the interferences a typical curve of ignition probabilities is developed in function from the distance to the pipe. (author)

  15. Thermoplastic liners for carbon steel pipelines

    2009-12-19

    Materials selection for pipe and fittings used to convey corrosive fluids has often been a challenge. Traditionally, exotic Corrosion Resistant Alloys (CRA) have been used in corrosive environments despite their high cost. Plastic lined carbon steel piping offers a cost effective alternative to the use of CRAs by eliminating corrosion, significantly reducing the use of toxic chemicals and the heavy metal usually present in CRAs. Thermoplastic Liners offer the combination of corrosion resistance and mechanical strength, which are unachievable with singular materials. Under pressure conditions, the liner is fully supported by the metalwork, while under vacuum conditions, the liner must be thick enough along with venting system to withstand the collapsing forces created by the negative pressure. Plastic liners have been used successfully to line and protect metallic pipelines for many years and have become an indispensable requirement of the oil and gas industry particularly with water injection and hydrocarbon services. In the case of internally corroded pipes, the use of thermoplastic liners for rehabilitation is an option to extend the lifetime of companies' assets, reduce maintenance cost and increase intervals between T and Is. For new construction, plastic liners in carbon steel pipes can compete technically and economically with pipelines of CRA materials and other corrosion inhibition systems. This paper describes various design features, installations of thermoplastic liners in comparison to other corrosion inhibition methods. (author)

    activities are involved in the flow of goods between place of origin and place of consumption or application:Demand forecasting, Facility site selection, Procurement,Materials handling, Packaging, Warehouse management, Inventory management,Order processing, Logistics communications, Transport, Reverse logistics. Because cost is incurred without adding value each time goods are handled (activity 4 at a terminal or storage facility, a primary logistics objective is to eliminate handling wherever possible. With the carriage of crude oil and petroleum products by pipeline this objective is fully met. Commodity intake, haulage, and discharge are combined in one process, usually a remote-controlled operation. Pipeline transport is a non-containerised bulk mode of transport thereby obviating the need for packaging (activity 5 and returning empty containers. Pipelines provide a direct and long-term link between these origins and destinations. If necessary a continuous service can be provided with no need for a return trip or a reverse pumping process (activity 11.The elimination of handling, packaging and reverse logistics activities contribute substantially to the high measure of economies of scale that pipeline transport enjoys. The article provides adscription of each of the eleven logistics activities in the context of pipeline transport. Effective logistics service is a prerequisite to help ensure that customers receive the required products at the desired quality and quantity, where and when needed. The most pertinent determinants of logistics service performance aresuitability, accessibility, goods security, transit time, reliability and flexibility. The article offers a discussion of the extent to which pipeline transport conforms to each of these measures of effectiveness.

    In the oil industry, monitoring pipeline structural integrity is necessary for both regulatory and environmental purposes. Weir-Jones Engineering Consultants developed an automated structural integrity monitoring (SIM) system, data on strain, displacement and temperature are continuously acquired and automatically transmitted to the monitoring personnel. The aim of this paper is to present this technology and its implementation on one of Inter Pipeline Fund's lines as well. The automated SIM equipment was installed on a new 42'' line at the crossing of the Clearwater River close to Fort McMurray. Results showed that this technology is a good way to monitor pipelines in remote locations, environmentally sensitive areas, river and embankment crossings and in locations where external forces can put the pipeline at risk; but it should not be used otherwise as that would not be cost effective. This paper described the developed automated SIM and showed that it should only be used in specific locations to be cost effective.

    The decommissioning and abandonment of platforms and pipelines are big challenges for the pipeline industry. This paper presents a review of the decommissioning and abandonment processes based on a study case, the Rabon Grande pipeline system. First, the applicable international codes, standards and regulations associated with the decommissioning of pipelines are discussed. Next, this paper presents a review of the decommissioning and abandonment options and considerations available for the study case. The Rabon Grande pipeline system, which was shut down and isolated in 1990 pending decommissioning, is used as an example of applying decommissioning and abandonment best practice and establishing a realistic scope of work. A decommissioning plan is developed in light of these previous studies, followed by an environmental impact assessment. It is found that contrary to what was done in the case of the Rabon Grande pipeline, when a pipeline is to be shutdown, the best practice methodology is to temporally or fully decommission the system as soon as possible.

    Trends in the oil and gas pipeline industry see that the demand for new technologies and engineered solutions for pipeline external coatings are increasing. In general, superior mechanical resistance and long term performance are being required in addition to operating at higher temperatures. This demand for more robust coatings has been created because of factors such as more remote fields, deep onshore reservoirs, deep water offshore fields and heavy oil that must be pumped at higher temperatures. The development of new techniques for pipeline construction is also exposing the coatings to more aggressive construction conditions. Because of this, the use of three layer and multi-layer polypropylene mainline coating systems have been growing considerably. Following this trend, the field joint coating manufacturers developed polypropylene systems and more recently had to work on engineered solutions required for recent offshore projects in Europe where very thick polypropylene field joint heat-shrinkable systems were provided. In addition, projects in remote locations such as the recently completed projects in the Brazilian Amazon required special logistics and field services. The growth of the mining industry in South America with slurry pipelines constructed in the recent years also demanded thicker, more robust coatings. The popularization of directional drilling and shore approach applications moved the industry to develop improved abrasion resistant coating systems such as using sacrificial elements to protect the primary coating integrity after the pipeline pull. PETROBRAS plans to replace existing thermally insulated pipelines crossing Great Sao Paulo. Therefore, pumping heavy oil at high temperatures created the need to develop improved mainline and field joint coatings to avoid having the same sort of problems they are facing in existing thermally insulated lines. Due to these needs, the field joint coating manufactures have been challenged to provide

    The Mid-Infrared Instrument (MIRI) Medium Resolution Spectrometer (MRS) is the only mid-IR Integral Field Spectrometer on board James Webb Space Telescope. The complexity of the MRS requires a very specialized pipeline, with some specific steps not present in other pipelines of JWST instruments, such as fringe corrections and wavelength offsets, with different algorithms for point source or extended source data. The MRS pipeline has also two different variants: the baseline pipeline, optimized for most foreseen science cases, and the optimal pipeline, where extra steps will be needed for specific science cases. This paper provides a comprehensive description of the MRS Calibration Pipeline from uncalibrated slope images to final scientific products, with brief descriptions of its algorithms, input and output data, and the accessory data and calibration data products necessary to run the pipeline.

    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.

    The approximately 200,000-mile fuel pipeline system in the US operates at flow rates up to 2.5 {times} 10{sup 6} gallons per hour (GPH). Most commercial technologies only provide on-line leak detection at about 0.3% of flow rate, i.e., about 7,500 GPH or larger. Detection of leaks at about 1 GPH or so is desirable both from a regulatory and leak-prevention standpoint. Brookhaven`s commercially-accepted perfluorocarbon tracer (PFT) technology for underground leak detection of utility industry dielectric fluids at leak rates less than 0.1 GPH, with new enhancements, will be able to cost-effectively detect fuel pipeline system leaks to about 1 GPH--3 orders-of-magnitude better than any on-line system. The magnitude of detected leaks would be calculable as well. Proposed mobile surveys (such as those used periodically in the gas pipeline industry) at about 110 to 120 miles per day would allow such small leaks to be detected at 10-ppb tagging levels (less than $1,500 of PFT for a 48-hour tag at the maximum transport rate) under worst-case meteorological dispersion conditions. Smaller leaks could be detected by proportionately larger tagging concentrations. Leaks would be pinpointed by subsequent conventional barholing and vapor analyses. There are no health nor safety issues associated with the use of the proposed technological approach nor any consequential environmental impacts associated with the proposed magnitudes of PFT tagging.

    Steel pipelines are huge ferromagnetic structures and can be easily subjected to arc blow during the DC arc welding process. The development of methods to avoid arc blow during pipeline DC arc welding is a major objective in the pipeline industry. This study developed a simple procedure to compensate the residual magnetic field in the groove during DC arc welding. A Gaussmeter was used to perform magnetic flux density measurements in pipelines in southern Mexico. These data were used to perform magnetic finite element simulations using FEMM. Different variables were studied such as the residual magnetic field in the groove or the position of the coil with respect to the groove. An empirical predictive equation was developed from these trials to compensate for the residual magnetic field. A new method of compensating for the residual magnetic field in the groove by selecting the number of coil turns and the position of the coil with respect to the groove was established.

    This paper presented an upstream pipeline integrity management program developed by Husky Energy. Three levels of risk assesment were used to optimize technical expertise and resources. The first level consisted of prioritizing gathering systems for the net assessment level. Level 2 was comprised of a subject matter expert (SME) based assessment performed in collaboration with industry operators and integrity management specialists. The assessment focused on the development of a mitigation strategy for higher risk pipelines. Level 3 investigated frequent failures of systematic mechanisms and pipelines with a high risk of failure. The risk assessment process was shown to effectively manage pipeline integrity when risk validation and mitigation actions were implemented, closely followed up, and evaluated in relation to their consistency. 9 refs., 3 tabs., 7 figs.

    The assessment of hydrogen content in pipeline steel is an essential requirement to monitor loss of pipe integrity with time and to prevent failures. The use of pipeline steels of increasing strength significantly reduces the threshold hydrogen concentration for hydrogen cracking. Cathodic protection and corrosion processes both contribute to accumulation of hydrogen as a function of time, which may eventually meet the cracking criteria. New and unique methodologies based on electronic property measurements offer the pipeline industry advanced non-destructive tools to provide quantified in-situ hydrogen content measurements in real-time. The use of low frequency impedance measurements as a non-contact sensor has been demonstrated for real-time determination of hydrogen content in coated pipeline steel specimens in the laboratory. Scale-up to field measurements is in progress, and the development and use of a field sensor are discussed.

    Full Text Available Optimal control, prevention and investigation of accidents, and detection of discrepancies in estimated gas supply and distribution volumes are relevant problems of trunkline operation. Efficient dealing with these production tasks is based on the numerical recovery of spacetime distribution of nonisothermal transient flow parameters of transmitted gas mixtures based on full-scale measurements in a substantially limited number of localities spaced considerable distances apart along the gas pipelines. The paper describes a practical method of such recovery by defining and solving a special identification problem. Simulations of product flow parameters in extended branched pipelines, involving calculations of the target function and constraint function for the identification problem of interest, are done in the 1D statement. In conclusion, results of practical application of the method in the gas industry are briefly discussed.

This paper discussed a research study currently being implemented to test the compatibility of girth-weld coatings with fusion-bonded epoxy (FBE) mainline coatings. The study is part of a larger research project initiated to develop standards and standard tests for coating performance. The pipeline samples will be conditioned for a 6 month period and subjected to impact; flexibility; adhesion; cathodic disbondment; squeeze; ice adhesion; and peel tests. Various coating samples will be prepared removing mainline coatings in certain parts of the pipes and replacing them with girth-weld coatings. Results of the study will be used to obtain feedback from industry and stakeholders in relation to the development of standards and further studies. 9 refs., 5 tabs., 1 appendix.

    The implementation of the coordinate rotational digital computer (CORDIC) algorithm with wave pipelining technique on field programmable gate array (FPGA) is described. All data in FPGA-based wave pipelining pass through a number of logic gates, in the same way that all data pass through the same number of registers in a conventional pipeline. Moreover, all paths are routed using identical routing resources. The manual placement, timing driven routing and timing analyzing techniques are applied to optimize the layout for achieving good path balance. Experimental results show that a 256-LUT logic depth circuit mapped on XC4VLX15-12 runs as high as 330MHz, which is a little lower than the speed of 336MHz based on the conventional 16-stage pipelining in the same chip. The latency of the wave pipelining circuit is 30.3ns, which is 36.4% shorter than the latency of 16-stage conventional pipelining circuit.

    Full Text Available From Enron to Evo is a long-term study of Enron and Shell’s construction of the Cuiabá pipeline in eastern Bolivia. The pipeline goes through the middle of the Chiquitano forest and affects a population of about 8,000. The project also has a negative impact on four critical ecoregions; the Gran Chaco and Cerrado, which are a mixture of grasslands and scattered trees, the Chiquitano dry forest, and the Pantanal wetlands. The Cuiabá pipeline has been highly contested by the thirty-four Chiquitano and two Ayoreo communities that live in the area. After years of field research, extensive interviews and document analyses, Dr. Hindery manages to expose the murky ways in which the hydrocarbon industry works in Bolivia. This is an industry where the powerful –mainly multinational oil companies and the Bolivian government– abuse the ecoregion and the indigenous populations that live on it.

    1987-03-24

    A tubular lining material for pipelines having bends or curved portions comprises a tubular textile jacket made of warps and wefts woven in a tubular form overlaid with a coating of a flexible synthetic resin. It is applicable onto the inner surface of a pipeline having bends or curved portions in such manner that the tubular lining material with a binder onto the inner surface thereof is inserted into the pipeline and allowed to advance within the pipeline, with or without the aid of a leading rope-like elongated element, while turning the tubular lining material inside out under fluid pressure. In this manner the tubular lining material is applied onto the inner surface of the pipeline with the binder being interposed between the pipeline and the tubular lining material. The lining material is characterized in that a part of all of the warps are comprised of an elastic yarn around which, over the full length thereof, a synthetic fiber yarn or yarns have been left-and/or right-handedly coiled. This tubular lining material is particularly suitable for lining a pipeline having an inner diameter of 25-200 mm and a plurality of bends, such as gas service pipelines or house pipelines, without occurrence of wrinkles in the lining material in a bend.

    This report highlights the Pipeline integrity Management methods being implemented by gas companies. These aim at maintaining the current high safety level, prevent major hazards, ensure the integrity of the pipeline and protect people and environment in the vicinity of the pipeline in the most cost effective way. It should be noticed that Pipeline Integrity Management aspects, technical and organisational, are included in the more general framework of the Safety Management System. Currently, more and more gas companies implement such a system on the basis of standards like ISO 9000 and so on. In this way, the report shows how practices of Pipeline Integrity Management are continually developing in order to adapt to their environment, and to improve performance. Past experience and imminent developments show that Pipeline Integrity Management is a flexible and efficient approach to improve safety in the long term. Consequently, Pipeline Integrity Management Systems are, under the control of authorities, the best alternative to additional safety regulations. Within the context of deregulation of the European markets and globalization Pipeline Integrity Management appears to be a tool to promote the gas industry in the eyes of the authorities, the market regulators and the customers (industrialists,...).

    The production of oil and gas from offshore oil fields is, nowadays, more and more important. As a result of the increasing demand of oil, and being the shallow water reserves not enough, the industry is pushed forward to develop and exploit more difficult fields in deeper waters. In this paper, there will be deployed the new design code DNV 2012 in terms of checking an offshore pipeline as compliance with the requests of this new construction code, using the Bentley Autopipe V8i. The August 2012 revision of DNV offshore standard, DNV- OS-F101, Submarine Pipeline Systems is supported by AutoPIPE version 9.6. This paper provides a quick walk through for entering input data, analyzing and generating code compliance reports for a model with piping code selected as DNV Offshore 2012. As seen in the present paper, the simulations comprise geometrically complex pipeline subjected to various and variable loading conditions. At the end of the designing process the Engineer has to answer to a simple question: is that pipeline safe or not? The pipeline set as an example, has some sections that are not complying in terms of size and strength with the code DNV 2012 offshore pipelines. Obviously those sections have to be redesigned in a manner to meet those conditions.

    One of the problems existing in the area of maintenance of systems for the transport of mass and / or energy is to examine the integrity of the lines of service in the basic infrastructure of cities and industries. For the development of maintenance, whether predictive, preventive or corrective is necessary to conduct the inspection of these lines. To carry out this task is necessary count on help of appropriate technological tools. The main tools for inspection of service lines come from the area of external inspection of pipelines and are also in development, the problem happens when we need to achieve internal or external failures in places of difficult access, and move the inspection equipment to places where it's going to fail. In these cases it is necessary to the use of mechatronic systems, more specifically robotic systems, which may be developed for inspection. This paper aims to present the main robotic systems used for inspection, especially for internal inspection of pipelines. These systems have been developed by the research groups in Brazil, Japan, and Belgium among others, giving up a classification of robots for inspection of pipelines and the main features necessary for its project.

    Pipelines are regarded by many as passive structures with the technology involved in their construction and operation being viewed as relatively simple and stable. If such is the case how can there be much room for cost improvement? In reality, there have been many technological and regulatory innovations required within the pipeline industry to meet the challenges posed by ever increasing consumer demand for hydrocarbons, the effects of aging infrastructure and a need to control operating and maintenance expenditures. The importance of technology management, as a subset of overall project management, is a key element of life cycle cost control. Assurance of public safety and the integrity of the system are other key elements in ensuring a successful pipeline project. The essentials of best practise project management from an owner/ operator's perspective are set out in the paper. Particular attention is paid to the appropriate introduction of new technology, strategic procurement practice and material selection, indicating that capital cost savings of up to 15% are achievable without harming life cycle cost. The value of partnering leading to technical innovation, cost savings and improved profitability for all the participants is described. Partnering also helps avoid duplicated effort through the use of common tools for design, planning schedule tracking and reporting. Investing in appropriate technology development has been a major source of cost reduction in recent years and the impact of a number of these recently introduced technologies in the areas of materials, construction processes and operation and maintenance are discussed in the paper.

    Pipeline rehabilitation and maintenance decisions are made using a wide variety of data, criteria, and expertise. The goal is to arrive at an optimal plan that considers risk and best return on Repair and Maintenance (R and M) expenditures for aging pipeline systems in both regulated and non-regulated environments. In order to achieve these goals, historical, operations, and assessment data is gathered, aligned and integrated as part of a baseline assessment. Integrity threats are identified based on operations and industry experience, and combined with potential consequences to public safety, the environment, and business to clearly delineate high risk exposure segments in the system. Integrity assessments are conducted in a prioritized manner, using the most appropriate technology and methods to address the threats. These include In Line Inspection technologies: MFL, Deformation, UT, INS (combinations thereof), Direct Assessment for EC and SCC threats, Hydro testing, and other indirect methods. From these results, decisions are made and R and M plans developed. To arrive at an optimal R and M plan, proper use of existing data, new integrity assessment data, and decision risk models is required. This paper presentation will detail the tactical aspect of an effective integrity management platform. Experience in decision support, operations priorities and execution of a rehabilitation plan using LinaView Pro{sup TM} integrity management system with risk-based integrity tools and maintenance planning will be presented. A process overview, results, and benefits will be given using these examples from operating oil and gas transmission pipelines. (author)

    Pipelines in industrial plants must be constantly monitored due to occurring erosion and corrosion. The determination of the residual wall thickness is generally carried out with ultrasound. Often, the critical points are difficult to access and the pipes insulated. The preparation and evaluation of a measurement is therefore very costly. The measuring system SONOWALL S ultrasonic probes are firmly attached to the pipeline and installed into isolation. The number and position of the probes can be freely selected. Often, the load is not known exactly why the monitoring of the pipe wall thickness over the entire circumference is necessary. The acoustic coupling to the pipe is done with proven adhesives that do not lose their adhesive strength even under changing ambient temperatures. The connecting cables are housed away up to 20 m in an easily accessible place in a terminal box. There can be done a wall thickness measurement with conventional ultrasonic testing devices. By using standardized components, the measuring system meets the requirements of DIN EN 12668 and DIN EN 14127.

    Recent technological advances have opened unprecedented opportunities for large-scale sequencing and analysis of populations of pathogenic species in disease outbreaks, as well as for large-scale diversity studies aimed at expanding our knowledge across the whole domain of prokaryotes. To meet the challenge of timely interpretation of structure, function and meaning of this vast genetic information, a comprehensive approach to automatic genome annotation is critically needed. In collaboration with Georgia Tech, NCBI has developed a new approach to genome annotation that combines alignment based methods with methods of predicting protein-coding and RNA genes and other functional elements directly from sequence. A new gene finding tool, GeneMarkS+, uses the combined evidence of protein and RNA placement by homology as an initial map of annotation to generate and modify ab initio gene predictions across the whole genome. Thus, the new NCBI's Prokaryotic Genome Annotation Pipeline (PGAP) relies more on sequence similarity when confident comparative data are available, while it relies more on statistical predictions in the absence of external evidence. The pipeline provides a framework for generation and analysis of annotation on the full breadth of prokaryotic taxonomy. For additional information on PGAP see https://www.ncbi.nlm.nih.gov/genome/annotation_prok/ and the NCBI Handbook, https://www.ncbi.nlm.nih.gov/books/NBK174280/.

    Full Text Available Convolutional encoding is used in almost all digital communication systems to get better gain in BER (Bit Error Rate, and all applications needs high throughput rate. The Viterbi algorithm is the solution in decoding process. The nonlinear and feedback nature of the Viterbi decoder makes its high speed implementation harder. One of promising approaches to get high throughput in the Viterbi decoder is to introduce a pipelining. This work applies a carry-save technique, which gets the advantage that the critical path in the ACS feedback becomes in one direction and get rid of carry ripple in the “Add” part of ACS unit. In this simulation and implementation show how this technique will improve the throughput of the Viterbi decoder. The design complexities for the bit-pipelined architecture are evaluated and demonstrated using Verilog HDL simulation. And a general algorithm in software that simulates a Viterbi Decoder was developed. Our research is concerned with implementation of the Viterbi Decoders for Field Programmable Gate Arrays (FPGA. Generally FPGA's are slower than custom integrated circuits but can be configured in the lab in few hours as compared to fabrication which takes few months. The design implemented using Verilog HDL and synthesized for Xilinx FPGA's.

    Pipeline defects are dislocations that connect the source region of the transistor with the drain region. They were widely reported to occur in CMOS, BiCMOS devices and recently in SOI technologies. They can reduce device yield either by affecting the devices functionality or by increasing the current consumption under stand-by conditions. In this work the electrical fingerprint of these dislocations is studied, its purpose is to enable us to identify these defects as the ones responsible for device failure. It is shown that the pipeline defects are responsible for a leakage current from source to drain in the transistors. This leakage has a resistive characteristic and it is lightly modulated by the body bias. It is not sensitive to temperature; vice versa the off-current of a good transistor exhibits the well-known exponential dependence on 1/T. The emission spectrum of these defects was studied and compared with the spectrum of a good transistor. The paper aims to show that the spectrum of a defective transistor is quite peculiar; it shows well defined peaks, whereas the spectrum of a good transistor under saturation conditions is characterized by a broad spectral light emission distribution. Finally the deep-level transient spectroscopy (DLTS) is tried on defective diodes.

    Twin oil (20 & 24 inch) and gas (20 & 48 inch) pipeline systems stretching 800 km are being constructed to connect offshore hydrocarbon deposits from the Sakhalin II concession in the North to an LNG plant and oil export terminal in the South of Sakhalin island. The onshore pipeline route follows a regional fault zone and crosses individual active faults at 19 locations. Sakhalin Energy, Design and Construction companies took significant care to ensure the integrity of the pipelines, should large seismic induced ground movements occur during the Operational life of the facilities. Complex investigations including the identification of the active faults, their precise location, their particular displacement values and assessment of the fault kinematics were carried out to provide input data for unique design solutions. Lateral and reverse offset displacements of 5.5 and 4.5 m respectively were determined as the single-event values for the design level earthquake (DLE)—the 1000-year return period event. Within the constraints of a pipeline route largely fixed, the underground pipeline fault crossing design was developed to define the optimum routing which would minimize stresses and strain using linepipe materials which had been ordered prior to the completion of detailed design, and to specify requirements for pipe trenching shape, materials, drainage system, etc. This Paper describes the steps followed to formulate the concept of the special trenches and the analytical characteristics of the Model.

    Pipeline PE-3, with a length of approximately 17 Km mainly inside of Guanabara Bay, connects the refinery of Duque de Caxias to the terminal of the Ilha D'Agua. It is used to export dark products from the refinery. Product transfer, by operational necessity, is conducted at a temperature of 75 deg C. This introduces a considerable load of tension on the pipeline, in addition to creating a fatigue-inducing thermal cycle. Because of this, and unlike almost all other existing oil and gas pipelines, PE-3 posses a zig zag configuration, alternating a straight tube with a curve of 10 degrees. This stands out as an innovative concept. Their are only two other similar installations in the world, but in very different conditions, thus conferring a pioneering aspect on this pipeline. Due to its criticality, the pipeline is predicated on complete certification in its entirety, from design to operation and in adherence with the strictest requirements. The environmental conditions encountered along its right of way, and the constructive tolerances imposed by the project, obligate the adoption of constructive and technical solutions that are themselves innovative in the terrestrial and marine realms. The principal objective of this work is to present a general overview of the methodology employed in PE-3 construction, installation and assembly. (author)

    The OCENSA pipeline system is vulnerable to geotechnical problems such as faults, landslides or creeping slopes, which are well-known in the Andes Mountains and tropical countries like Colombia. This paper proposes a methodology to evaluate the pipe behaviour during the soil displacements of slow landslides. Three different cases of analysis are examined, according to site characteristics. The process starts with a simplified analytical model and develops into 3D finite element numerical simulations applied to the on-site geometry of soil and pipe. Case 1 should be used when the unstable site is subject to landslides impacting significant lengths of pipeline, pipeline is straight, and landslide is simple from the geotechnical perspective. Case 2 should be used when pipeline is straight and landslide is complex (creeping slopes and non-conventional stabilization solutions). Case 3 should be used if the pipeline presents vertical or horizontal bends.

    The initial phase of a pipeline integrity management program (IMP) is conducting a baseline assessment of the pipeline system and segments as part of Quantitative Risk Assessment (QRA). This gives the operator's integrity team the opportunity to identify critical areas and deficiencies in the protection, maintenance, and mitigation strategies. As a part of data gathering and integration of a wide variety of sources, in-line inspection (ILI) data is a key element. In order to move forward in the integrity program development and execution, the baseline geometry of the pipeline must be determined with accuracy and confidence. From this, all subsequent analysis and conclusions will be derived. Tuboscope Pipeline Services (TPS), in conjunction with Pipeway Engenharia of Brazil, operate ILI inertial navigation system (INS) and Caliper geometry tools, to address this integrity requirement. This INS and Caliper ILI tool data provides pipeline trajectory at centimeter level resolution and sub-metre 3D position accuracy along with internal geometry - ovality, dents, misalignment, and wrinkle/buckle characterization. Global strain can be derived from precise INS curvature measurements and departure from the initial pipeline state. Accurate pipeline elevation profile data is essential in the identification of sag/over bend sections for fluid dynamic and hydrostatic calculations. This data, along with pipeline construction, operations, direct assessment and maintenance data is integrated in LinaViewPRO{sup TM}, a pipeline data management system for decision support functions, and subsequent QRA operations. This technology provides the baseline for an informed, accurate and confident integrity management program. This paper/presentation will detail these aspects of an effective IMP, and experience will be presented, showing the benefits for liquid and gas pipeline systems. (author)

  14. DETECTION OF INTERSTATE LIQUIDS PIPELINE LEAKS: FEASIBILITY EVALUATION.

    The approximately 200,000-mile fuel pipeline system in the U.S. operates at flow rates up to 2.5 x 10{sup 6}gallons per hour (GPH). Most commercial technologies only provide on-line leak detection at about 0.3% of flow rate, i.e., about 7,500 GPH or larger. Detection of leaks at about 1 GPH or so is desirable both from a regulatory and leak-prevention standpoint. Brookhaven's commercially-accepted perfluorocarbon tracer (PFT) technology for underground leak detection of utility industry dielectric fluids at leak rates less than 0.1 GPH, with new enhancements, will be able to cost-effectively detect fuel pipeline system leaks to about 1 GPH--3 orders-of-magnitude better than any on-line system. The magnitude of detected leaks would be calculable as well. Proposed mobile surveys (such as those used periodically in the gas pipeline industry) at about 110 to 120 miles per day would allow such small leaks to be detected at 10-ppb tagging levels (less than $1,500 of PFT for a 48-hour tag at the maximum transport rate) under worst-case meteorological dispersion conditions. Smaller leaks could be detected by proportionately larger tagging concentrations. Leaks would be pinpointed by subsequent conventional barholing and vapor analyses. There are no health nor safety issues associated with the use of the proposed technological approach nor any consequential environmental impacts associated with the proposed magnitudes of PFT tagging.

    The demands for monitoring of pipeline operations have recently increased greatly due to new regulatory requirements. Most companies rely upon conventional System Control and Data Acquisition (SCADA) system architecture to meet their needs. Current systems are often plagued by limited data conversion and processing capacity at the workstations. A state-of-the-art Data Acquisition Node (DAN) that relieves the workstation of much of its workload is described in this paper. Use of this DAN may eliminate the need for installing completely new systems. It facilitates marrying foreign devices to existing operation monitoring systems to satisfy new regulatory requirements. The DAN allows a system to utilize commercial communications satellites or other communication networks and real-time, object oriented programming and different devices and data requirements without the necessity of custom software development.

    Transient radio phenomena and pulsars are one of six LOFAR Key Science Projects (KSPs). As part of the Transients KSP, the Pulsar Working Group (PWG) has been developing the LOFAR Pulsar Data Pipelines to both study known pulsars as well as search for new ones. The pipelines are being developed for the Blue Gene/P (BG/P) supercomputer and a large Linux cluster in order to utilize enormous amounts of computational capabilities (50Tflops) to process data streams of up to 23TB/hour. The LOFAR pipeline output will be using the Hierarchical Data Format 5 (HDF5) to efficiently store large amounts of numerical data, and to manage complex data encompassing a variety of data types, across distributed storage and processing architectures. We present the LOFAR Known Pulsar Data Pipeline overview, the pulsar beam-formed data format, the status of the pipeline processing as well as our future plans for developing the LOFAR Pulsar Search Pipeline.

    This paper describes how the OPUS pipeline, currently used for processing science data from the Hubble Space Telescope (HST), was used as the backbone for developing the science data pipeline for a much smaller mission. The far ultraviolet spectroscopic explorer (FUSE) project selected OPUS for its data processing pipeline platform and selected the OPUS team at the STScI to write the FUSE pipeline applications. A total of 105 new modules were developed for the FUSE pipeline. The foundation of over 250 modules in the OPUS libraries allowed development to proceed quickly and with considerable confidence that the underlying functionality is reliable and robust. Each task represented roughly 90 percent reuse, and the project as a whole shows over 70 percent reuse of the existing OPUS system. Taking an existing system that is operational, and will be maintained for many years to come, was a key decision for the FUSE mission. Adding the extensive experience of the OPUS team to the task resulted in the development of a complete telemetry pipeline system within a matter of months. Reusable software has been the siren song of software engineering and object- oriented design for a decade or more. The development of inexpensive software systems by adapting existing code to new applications is as attractive as it has been elusive. The OPUS telemetry pipeline for the FUSE mission has proven to be a significant exception to that trend.

    The offshore pipeline network in the U.S. Gulf of Mexico is the largest and most transparent system in the world. A review of deepwater projects in the region provides insight into construction cost and installation methods and the evolution of contract strategies. Pipeline projects are identified as export systems, infield flowline systems, and combined export and infield systems, and three dozen deepwater pipeline installations from 1980-2014 are described based on OTC/SPE industry publications and press release data. Export lines and infield flowlines are equally represented and many projects used a combination of J-lay, S-lay and reel methods with rigid steel, flexible line, and pipe-in-pipe systems. The average 2014 inflation-adjusted cost for pipeline projects based on OTC/SPE publications was 2.76 million/mi and ranged from 520 000/mi to 12.94 million/mi. High cost pipelines tend to be short segments or specialized pipeline. Excluding the two cost endpoints, the majority of projects ranged from 1 to 6 million/mi. The average inflation-adjusted cost to install deepwater pipelines in the U.S. Gulf of Mexico based on available public data is estimated at 3.1 million/mi.

    The design of Capixaba North Terminal pipelines (TNC) became very complex, once the pipelines are exposed to elevated temperature variations. As the pipelines are buried, the interaction with the seabed can become critical with the thermal expansion development, since an axial compressive force arise, reaching critical values and then leading the pipeline to the thermo mechanical instability phenomenon. To minimize these effects, the pipeline will cross the shore approach through a horizontal directional drilling, and expansion loops and intermediate tie-ins took place on his route in order to permit pipeline displacements, working thermally. The objective of this present work is to develop a numerical model, able to analyze the entire pipeline stress, strain and displacements, considering different kinds of soil along of his route. The influence of expansion loops is evaluated and a comparative analysis in order to discover the minimum curvature radius at the directional drilling region is carried out. This study defines a methodology based on the developed numerical model which will be extended to future applications in subsea buried pipeline design. (author)

    Full Text Available Looking at the struggle between Iran, Russia, China, and the US over their preferred pipeline routes for Central Asian oil and gas gives a good glimpse as to the world's future geopolitical order. Despite the formidable difficulties in building pipelines, those four powers are converging upon the region with an eagerness that is almost desperate. In previous eras, a country's military was the sole arbiter of her strength, but today her economy has become nearly as important, if not more so, and all industrial economies – and militaries – run on oil and gas. The US and China desire those resources to fuel their power plants, factories, automobiles, aircraft, and armored vehicles. Iran and Russia want the pipelines to go through their territory in order to claim transit fees and use the resources as political tools. For each country wresting control of the Central Asian oil and gas is necessarily a vital part of its grand strategy.

    Pipeline inspection gauges (pigs) have been used for many years to perform various maintenance operations in oil and gas pipelines. Different pipeline parameters can be inspected during the pig journey. Although pigs use many sensors to detect the required pipeline parameters, matching these data with the corresponding pipeline location is considered a very important parameter. High-end, tactical-grade inertial measurement units (IMUs) are used in pigging applications to locate the detected problems of pipeline using other sensors, and to reconstruct the trajectories of the pig. These IMUs are accurate; however, their high cost and large sizes limit their use in small diameter pipelines (8″ or less). This paper describes a new methodology for the use of MEMS-based IMUs using an extended Kalman filter (EKF) and the pipeline junctions to increase the position parameters' accuracy and to reduce the total RMS errors even during the unavailability of above ground markers (AGMs). The results of this new proposed method using a micro-electro-mechanical systems (MEMS)-based IMU revealed that the position RMS errors were reduced by approximately 85% compared to the standard EKF solution. Therefore, this approach will enable the mapping of small diameter pipelines, which was not possible before.

    Implementation of recent federal and state regulations promulgated to protect wetlands makes information on effects of gas pipeline rights-of-way (ROWs) in wetlands essential to the gas pipeline industry. This study is designed to record vegetational changes induced by the construction of a large-diameter gas pipeline through deciduous forested wetlands. Two second-growth forested wetland sites mapped as Lenawee soils, one mature and one subjected to recent selective logging, were selected in Midland County, Michigan. Changes in the adjacent forest and successional development on the ROW are being documented. Cover-class estimates are being made for understory and ROW plant species using 1 {times}1-m quadrats. Counts are also being made for all woody species with stems < 2 cm in diameter at breast height (dbh) in the same plots used for cover-class estimates. Individual stem diameters and species counts are being recorded for all woody understory and overstory plants with stems {ge}2 cm dbh in 10 {times} 10-m plots. Although analyses of the data have not been completed, preliminary analyses indicate that some destruction of vegetation at the ROW forest edge may have been avoidable during pipeline construction. Rapid regrowth of many native wetland plant species on the ROW occurred because remnants of native vegetation and soil-bearing propagules of existing species survived on the ROW after pipeline construction and seeding operations. 91 refs., 11 figs., 3 tabs.

    Problems involving wax deposition threaten seriously crude pipelines both economically and operationally. Wax deposition in oil pipelines is a complicated problem having a number of uncertainties and indeterminations. The Grey System Theory is a suitable theory for coping with systems in which some information is clear and some is not, so it is an adequate model for studying the process of wax deposition.In order to predict accurately wax deposition along a pipeline, the Grey Model was applied to fit the data of wax deposition rate and the thickness of the deposited wax layer on the pipe-wall, and to give accurate forecast on wax deposition in oil pipelines. The results showed that the average residential error of the Grey Prediction Model is smaller than 2%. They further showed that this model exhibited high prediction accuracy. Our investigation proved that the Grey Model is a viable means for forecasting wax deposition.These findings offer valuable references for the oil industry and for firms dealing with wax cleaning in oil pipelines.

    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)

  2. Essays on the economics of natural gas pipelines

    Science.gov (United States)

    Oliver, Matthew E.

    The natural gas pipeline transportation industry is comprised of a primary market and a secondary market. In the primary market, pipelines sell 'firm' transport capacity contracts to gas traders, local distribution companies, and other parties. The (per unit) secondary market value of transport is rarely comparable to the regulated primary market two-part tariff. When and where available capacity in the secondary market is scarce, its value can far exceed the primary market tariffs paid by firm contract holders, generating scarcity rents. The following essays demonstrate that this phenomenon has predictable effects on natural gas spot prices, firm capacity reservations, the pipeline's capacity construction and expansion decisions, and the economic welfare of producers and consumers at the market hubs connected by the pipeline. Chapter 1 provides a theoretical framework for understanding how pipeline congestion affects natural gas spot prices within the context of the current regulatory environment, and empirically quantifies this effect over a specific regional pipeline network. As available pipeline capacity over a given route connecting two hubs becomes scarce, the spot prices for gas at the hubs are driven apart---a phenomenon indicative of some market friction that inhibits the ability of spot price arbitrage to fully integrate the two prices, undermining economic efficiency. The theoretical component of Chapter 1 illuminates a potential source of this friction: the deregulated structure of the secondary market for gas transportation services. To support and quantify the predictions of the theoretical model, the empirical component demonstrates that the effect of congestion on the secondary market value of transport---the key factor in driving apart spot prices---can be quite strong. Coefficient estimates indicate that dramatic increases in transport costs are likely to result from marginal increases in congestion. This result has important implications because

  3. Astronomical pipeline processing using fuzzy logic

    Shamir, Lior

    In the past few years, pipelines providing astronomical data have been becoming increasingly important. The wide use of robotic telescopes has provided significant discoveries, and sky survey projects such as SDSS and the future LSST are now considered among the premier projects in the field astronomy. The huge amount of data produced by these pipelines raises the need for automatic processing. Astronomical pipelines introduce several well-defined problems such as astronomical image compression, cosmic-ray hit rejection, transient detection, meteor triangulation and association of point sources with their corresponding known stellar objects. We developed and applied soft computing algorithms that provide new or improved solutions to these growing problems in the field of pipeline processing of astronomical data. One new approach that we use is fuzzy logic-based algorithms, which enables the automatic analysis of the astronomical pipelines and allows mining the data for not-yet-known astronomical discoveries such as optical transients and variable stars. The developed algorithms have been tested with excellent results on the NightSkyLive sky survey, which provides a pipeline of 150 astronomical pictures per hour, and covers almost the entire global night sky.

  4. Consensus between pipelines in structural brain networks.

    Directory of Open Access Journals (Sweden)

    Christopher S Parker

    Full Text Available Structural brain networks may be reconstructed from diffusion MRI tractography data and have great potential to further our understanding of the topological organisation of brain structure in health and disease. Network reconstruction is complex and involves a series of processesing methods including anatomical parcellation, registration, fiber orientation estimation and whole-brain fiber tractography. Methodological choices at each stage can affect the anatomical accuracy and graph theoretical properties of the reconstructed networks, meaning applying different combinations in a network reconstruction pipeline may produce substantially different networks. Furthermore, the choice of which connections are considered important is unclear. In this study, we assessed the similarity between structural networks obtained using two independent state-of-the-art reconstruction pipelines. We aimed to quantify network similarity and identify the core connections emerging most robustly in both pipelines. Similarity of network connections was compared between pipelines employing different atlases by merging parcels to a common and equivalent node scale. We found a high agreement between the networks across a range of fiber density thresholds. In addition, we identified a robust core of highly connected regions coinciding with a peak in similarity across network density thresholds, and replicated these results with atlases at different node scales. The binary network properties of these core connections were similar between pipelines but showed some differences in atlases across node scales. This study demonstrates the utility of applying multiple structural network reconstrution pipelines to diffusion data in order to identify the most important connections for further study.
