  20. Puncturing the pipeline: Do technology companies alienate women in recruiting sessions?

    Science.gov (United States)

    Wynn, Alison T; Correll, Shelley J

    2018-02-01

    A 'chilly' environment limits women's advancement through the educational pipeline leading to jobs in science and technology. However, we know relatively little about the environment women encounter after making it through the educational pipeline. Do technology companies create environments that may dampen women's interest at the juncture when they are launching their careers? Using original observational data from 84 recruiting sessions hosted by technology companies at a prominent university on the US West Coast, we find that company representatives often engage in behaviors that are known to create a chilly environment for women. Through gender-imbalanced presenter roles, geek culture references, overt use of gender stereotypes, and other gendered speech and actions, representatives may puncture the pipeline, lessening the interest of women at the point of recruitment into technology careers.

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

    Science.gov (United States)

    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

  8. Insurance companies' perspectives on the orphan drug pipeline.

    Science.gov (United States)

    Handfield, Robert; Feldstein, Josh

    2013-11-01

    Rare diseases are of increasing concern to private and public healthcare insurance plans. Largely neglected by manufacturers before the 1983 passing of the Orphan Drug Act (ODA), orphan drugs have become a commercialization target of steadily increasing importance to the healthcare industry. The ODA mandates the coverage of rare diseases, which are defined in research communities as diseases that are so infrequent that there is no reasonable expectation of a drugmaker recovering the cost of developing that drug. To determine the views of leading commercial US payers regarding providing access to and coverage for orphan drugs; to assess whether and to what degree cost-effectiveness analysis (CEA) is viewed by payers as relevant to rare disease coverage. The study sample was identified through a call for action sent by America's Health Insurance Plans to its members, resulting in 4 interviews conducted and 3 completed surveys from a total of 7 companies. These 7 US health insurance companies represent approximately 75% of the US private insurance market by revenue and include approximately 157 million covered lives (using self-reported data from insurance companies). Representatives of 3 companies responded to the survey, and representatives of 4 companies were interviewed via the phone. The interviews were conducted with subject matter experts at each company and included 2 senior vice presidents of a pharmacy program, 1 chief medical director, and 1 head of pharmacoeconomics. The surveys were completed by 1 vice president of clinical pharmacy strategy, 1 chief pharmacy director, and 1 medical director. Based on the responses in this study, approximately 67% of US private insurance companies are concerned about orphan drugs, but only approximately 17% have developed meaningful strategies for addressing the cost of orphan drugs. Of the companies who do have such a strategy, 100% are unsure how to determine the best economic assessment tools to control orphan drug

  11. A root cause analysis approach to risk assessment of a pipeline network for Kuwait Oil Company

    Energy Technology Data Exchange (ETDEWEB)

    Davies, Ray J.; Alfano, Tony D. [Det Norske Veritas (DNV), Rio de Janeiro, RJ (Brazil); Waheed, Farrukh [Kuwait Oil Company, Ahmadi (Kuwait); Komulainen, Tiina [Kongsberg Oil and Gas Technologies, Sandvika (Norway)

    2009-07-01

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

  12. Powers of detection : technology companies vie to capture leak survey business for natural gas pipelines

    Energy Technology Data Exchange (ETDEWEB)

    Byfield, M.

    2005-09-01

    ITT Industries Inc., Physical Sciences Inc., and LaSen Inc. are 3 American companies leading the way to find more efficient methods for identifying leaks from natural gas pipelines. Edmonton-based Synodon Inc. has recently joined the leaders with its newly developed and more sensitive equipment that it hopes to have on the market by the summer of 2006. Leak detection technology was first developed in 1993 in response to concerns about the reliability of aging pipeline infrastructure. In addition to safety concerns, there are concerns over global warming. Methane is a potential greenhouse gas and the United states Environmental Protection Agency estimates that 300 billion cubic feet escape into the atmosphere every year from pipeline leaks. The 2002 Pipeline Safety Improvement Bill in the United States stipulates that leak inspections must be conducted up to 4 times per year in densely populated areas. Violators face fines as high as $1 million. In response to the pipeline safety bill, Synodon raised private equity financing to commercialize an airborne leak detection technology stemming from Canada's space program. In the United States, leak detection technologies that appear likely to take 5 to 20 years for commercialization have been been financed by the Department of Energy and the Office of Pipeline Safety. This paper summarized 5 leak detection prototypes, including ITT's Airborne Natural Gas Emission LiDAR (ANGEL) system which targets high-pressure, long-distance pipelines in North America, LaSen's Airborne LiDAR Pipeline Inspection System (ALPIS) based on DIAL Technology, and a hand-held remote methane leak detector developed jointly by Physical Sciences Inc. of Massachusetts and Houston-based Heath Consultants Inc. Synodon claims that hand-held detectors are too slow and that LiDAR systems still aren't reliable for detection of leaks much below 500 scf/h. Synodon's realSens technology may be more difficult to develop, but it detects

    Since the operation of PS09 SR module in 2007, it has been observed that there is vibration in various parts of the structures, on various segments of piping, and on appurtenance items. At DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) request, ORNL Subject Matter Experts support PHMSA in its review and analysis of the observed vibration phenomenon. The review and analysis consider possible effects of pipeline design features, vibration characteristics, machinery configuration, and operating practices on the structural capacity and leak tight integrity of the pipeline. Emphasis is placed on protection of welded joints and machinery against failure from cyclic loading. A series of vibration measurements were carried out by the author during the site visit to PS09, the power of the operating pump during the data collection is at about 2970KW, which is less than that of APSC's vibration data collected at 3900KW. Thus, a first order proportional factor of 4900/2970 was used to project the measured velocity data to that of APSC's measurement of the velocity data. It is also noted here that the average or the peak-hold value of the measured velocity data was used in the author's reported data, and only the maximum peak-hold data was used in APSC's reported data. Therefore, in some cases APSC's data is higher than the author's projective estimates that using the average data. In general the projected velocity data are consistent with APSC's measurements; the examples of comparison at various locations are illustrated in the Table 1. This exercise validates and confirms the report vibration data stated in APSC's summary report. After the reinforcement project for PS09 Station, a significant reduction of vibration intensity was observed for the associated pipelines at the SR Modules. EDI Co. provided a detailed vibration intensity investigation for the newly reinforced Pump Module structures and the associated

    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.

  19. Pipelines 'R' us

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

    In order to fulfill contractual agreements, three Bolivian companies decided to create Transierra S.A., a gas transportation company that would increase the gas transportation capacity from the gas fields, located in the Southern part of Bolivia. The overall objective was to build and operate a gas pipeline from Yacuiba to Rio Grande in time to comply with already agreed dates to star commercial operation. The creation of the company and the construction process were conducted in a highly competitive and regulated environment. Construction completion schedules were tight; therefore, under the previously mentioned scenario, the company implemented creative strategies to achieve its goals. (author)

  1. United States petroleum pipelines: An empirical analysis of pipeline sizing

    Science.gov (United States)

    Coburn, L. L.

    1980-12-01

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

    Pipeline operators are continuously working to improve the safety of their systems and operations. In the US both liquid and gas pipeline operators have worked with the regulators over many years to develop more systematic approaches to pipeline integrity management. To successfully manage pipeline integrity, vast amounts of data from different sources needs to be collected, overlaid and analyzed in order to assess the current condition and predict future degradation. The efforts undertaken by the operators has had a significant impact on pipeline safety, nevertheless, during recent years we have seen a number of major high profile accidents. One can therefore ask how effective the pipeline integrity management systems and processes are. This paper will present one methodology 'The Pipeline System Operability Review' that can evaluate and rate the effectiveness of both the management systems and procedures, as well as the technical condition of the hardware. The result from the review can be used to compare the performance of different pipelines within one operating company, as well as benchmark with international best practices. (author)

    Regulated US interstate pipelines began 1995 under the momentum of impressive efficiency improvements in 1994. Annual reports filed with the US Federal Energy Regulatory Commission (FERC) show that both natural-gas and petroleum liquids pipeline companies increased their net incomes last year despite declining operating revenues. This article discusses trends in the pipeline industry and gives data on the following: pipeline revenues, incomes--1994; current pipeline costs; pipeline costs--estimated vs. actual; current compressor construction costs; compressor costs--estimated vs. actual; US interstate mileage; investment in liquids pipelines; 10-years of land construction costs; top 10 interstate liquids pipelines; top 10 interstate gas pipelines; liquids pipeline companies; and gas pipeline companies

  7. Pipeline Drag Reducers

    International Nuclear Information System (INIS)

    2004-01-01

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

    1998-01-01

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

    Energy Technology Data Exchange (ETDEWEB)

    Rook, M.E.

    The spray of leakage from the wood stave water supply pipeline serving the New England Power Company's (NEPCO) Searsburg hydroelectric development had caused this facility to be dubbed ''The Searsburg Car Wash.'' In July, 1982, excessive leakage from this pipeline prompted NEPCO to perform a technical inspection which would inform the company's decision to replace, repair, or abandon the pipeline. The inspection indicated that a combination of interrelated factors has led to rapid deterioration. The feasibility study, which included a benefit -cost analysis of a times replacement with a continued repair program weighed annually by a risk factor representing the probability of pipeline failure during the replacement period, determined that direct replacement was most advantageous. 4 figures, 1 figures.

    Folga, S. M.; Decision and Information Sciences

    2007-11-01

    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

    2007-07-01

    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.

  19. Global offshore pipeline markets

    International Nuclear Information System (INIS)

    Knight, R.; Parsons, B.

    2001-01-01

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

  20. Environmental audit guidelines for pipelines

    International Nuclear Information System (INIS)

    1991-01-01

    Environmental auditing is a form of management control which provides an objective basis by which a company can measure the degree of compliance with environmental regulations. Other benefits of this type of auditing include improved environmental management, furthering communication on environmental issues of concern within the company, and provision of documentation on environmental diligence. A series of environmental audit guidelines for pipelines is presented in the form of lists of questions to be asked during an environmental audit followed by recommended actions in response to those questions. The questions are organized into seven main categories: environmental management and planning; operating procedures; spill prevention; management of wastes and hazardous materials; environmental monitoring; construction of pipelines; and pipeline abandonment, decommissioning and site reclamation

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

    Constructing natural gas pipelines in wide areas requires investments of a huge amount. Many countries are building natural gas supply infrastructures under public support as nations' basic policy of promoting use of natural gas. This paper describes the present conditions of building pipelines in Western Europe, the U.S.A., Korea and Taiwan. In Western Europe, transporting companies established in line with the national policy own trunk pipelines and storage facilities, and import and distribute natural gas. The U.S.A. has 2300 small and large pipeline companies bearing transportation business. Pipelines extend about 1.9 million kilometers in total, with trunk pipelines accounting for about 440,000 kilometers. The companies are given eminent domain for the right of way. Korea has a plan to build a pipeline network with a distance of 1600 kilometers in around 2000. Taiwan has completed trunk pipelines extending 330 kilometers in two years. In Japan, the industry is preparing draft plans for wide area pipeline construction. 5 figs., 1 tab.

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

  6. Oil pipeline energy consumption and efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Hooker, J.N.

    1981-01-01

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

    This study presents an experimental work in a petrochemical company for scanning a buried pipeline using Tc{sup 99m} radiotracer based on the measured velocity changes, in order to determine the flow reduction along a pipeline. In this work, Tc{sup 99m} radiotracer was injected into the pipeline and monitored by sodium iodide scintillation detectors located at several positions along the pipeline. The flow velocity has been calculated between every two consecutive detectors along the pipeline. Practically, six experiments have been carried out using two different data acquisition systems, each of them being connected to four detectors. During the fifth experiment, a bypass was discovered between the scanned pipeline and another buried parallel pipeline connected after the injection point. The results indicate that the bypass had a bad effect on the volumetric flow rate in the scanned pipeline.

    2009-07-01

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

  16. Customer service drives pipelines' reorganization

    International Nuclear Information System (INIS)

    Share, J.

    1997-01-01

    The concept behind formation of Enron Transportation and Storage tells plenty about this new gas industry. When executives at the Enron Gas Pipeline Group considered plans last year to streamline operations by merging the support functions of Transwestern Pipeline and their other wholly owned pipeline company, Northern Natural Gas, seamless customer service was foremost on their agenda. Instead of worrying about whether employees would favor one pipeline over the other, perhaps to the detriment of customers, they simply created a new organization that everyone would swear the same allegiance to. The 17,000-mile, 4.1 Bcf/d Northern system serves the upper Midwest market and two major expansion projects were completed there last year. Transwestern is a 2,700-mile system with an eastward capacity of 1 Bcf/d and westward of 1.5 Bcf/, that traditionally served California markets. It also ties into Texas intrastate markets and, thanks to expansion of the San Juan lateral, to southern Rocky Mountain supplies. Although Enron Corp. continues to position itself as a full-service energy company, the Gas Pipeline Group continues to fuel much of corporate's net income, which was $584 million last year. With ET and S comprising a significant portion of GPG's income, it was vital that the merger of Northern's 950 employees with Transwestern's 250 indeed be a seamless one. It was not easy either psychologically or geographically with main offices in Omaha, NE and Houston as well as operations centers in Minneapolis, MN; Amarillo, TX; W. Des Moines, IA; and Albuquerque, NM. But the results have been gratifying, according to William R. Cordes, President of ET and S and Nancy L. Gardner, Executive Vice President of Strategic Initiatives

    2010-07-01

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

  3. Induced AC voltages on pipelines may present a serious hazard

    International Nuclear Information System (INIS)

    Kirkpatrick, E.L.

    1997-01-01

    The problem of induced AC voltages on pipelines has always been with us. Early pipeline construction consisted of bare steel or cast iron pipe, which was very well grounded. Bell and spigot, mechanical, or dresser-style joint couplings often were used, creating electrically discontinuous pipelines which are less susceptible to AC induction. Although induced AC affects any pipeline parallel to a high-voltage alternating current (HVAC) power line, the effects were not noticeable on bare pipelines. With the advent of welded steel pipelines, modern cathodic protection (CP) methods and materials, and the vastly improved quality of protective coatings, induced AC effects on pipelines have become a significant consideration on many pipeline rights-of-way. In the last two to three decades, one has been seeing much more joint occupancy of the same right-of-way by one or more pipelines and power lines. As the cost of right-of-way and the difficulty in acquisition, particularly in urban areas, have risen, the concept of joint occupancy rights-of-way has become more attractive to many utility companies. Federal and state regulations usually insist on joint-use right-of-way when a utility proposes crossing regulated or publicly owned lands, wherever there is an existing easement. Such joint use allows the induced AC phenomena to occur and may create electrical hazards and interference to pipeline facilities. Underground pipelines are especially susceptible if they are well-coated and electrically isolated for CP

  6. Outlook '98 - Gas and oil pipelines

    International Nuclear Information System (INIS)

    Curtis, B.

    1998-01-01

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

    1994-01-01

    Pipelines to be decontaminated are parts of pipelines contaminated with radioactive materials, and they are connected to a fluid transfer means (for example, a bladeless pump) and a ball collector by way of a connector. The fluid of a mixture of chemical decontaminating liquid and spheres is sent into pipelines to be decontaminated. The spheres are, for example, heat resistant porous hard or soft rubber spheres. The fluid discharged from the pipelines to be decontaminated are circulated by way of bypassing means. The inner surface of the pipelines is decontaminated by the circulation of the fluid. When the bypass means is closed, the fluid discharged from the pipelines to be decontaminated is sent to the ball collector, and the spheres are captured by a hopper. Further, the liquid is sent to the filtrating means to filter the chemical contaminating liquid, and sludges contained in the liquid are captured. (I.N.)

  8. Overview of slurry pipelines

    1982-01-01

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

    2009-07-01

    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.

    2009-12-19

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

    Von Bassenheim, G.; Mohitpour, M.; Klaudt, D.; Jenkins, A.

    2000-01-01

    The challenges, risks and uncertainties that the natural gas industry faces in developing market-based pipeline projects were discussed. Market-based pipeline investments are fundamentally different from user-driven projects. Market-based projected involve finding enough energy users and linking them with a pipeline infrastructure to viable supplies of natural gas. Each unique project is developed individually and requires a strong corporate vision and support before it can be successfully implemented. The three phases of a pipeline investment include the business development phase, the project development phase, and the implementation/operations phase. Market-based companies will need a clear vision for long-term goals and the desire to succeed. The company will have to prepare a detailed strategy and policies that clearly define geographic areas of operations, risk tolerance, availability of capital and expected project performance. 3 refs., 3 tabs., 2 figs

    European, North American and Australian pipeline companies are busy building pipelines to transport natural gas to power stations throughout South East Asia. Many countries, such as Thailand, Malaysia, Singapore and Indonesia, have economies expanding at more than eight percent a year. Cambodia and Laos are awaiting energy development. Myanmar will not only benefit from the global economic expansion but from the flourishing economies of nearby Thailand and Malaysia which are now investing in neighbouring countries, while their national petroleum companies are starting to operate worldwide. It is the ever expanding rush of industrialisation, urbanisation and the move to raise living standards throughout the region that is accelerating the need for more power stations, both gas and coal-fired, throughout South East Asia.

    International Nuclear Information System (INIS)

    Scholes, W.

    1994-01-01

    European, North American and Australian pipeline companies are busy building pipelines to transport natural gas to power stations throughout South East Asia. Many countries, such as Thailand, Malaysia, Singapore and Indonesia, have economies expanding at more than eight percent a year. Cambodia and Laos are awaiting energy development. Myanmar will not only benefit from the global economic expansion but from the flourishing economies of nearby Thailand and Malaysia which are now investing in neighbouring countries, while their national petroleum companies are starting to operate worldwide. It is the ever expanding rush of industrialisation, urbanisation and the move to raise living standards throughout the region that is accelerating the need for more power stations, both gas and coal-fired, throughout South East Asia.

    Alliance Pipeline has taken on as its primary role to improve the competitive position of the Western Canadian Sedimentary Basin (WCSB), to increase market access for WCSB production, to provide a link for North American gas pricing, and to increase the total gas supply available across North America to serve current and future requirements. A summary of the company's partnership structure and construction program is presented. Also discussed were issues facing Canadian transporters and producers such as: pricing dynamics, gas supplies, regulatory change, competition, convergence, pipeline integrity, land issues, environmental issues, aboriginal issues, cost structures and taxes. The potential impact of the Alliance Pipeline coming on-stream in October 2000 on existing pipelines, possible future pipelines and on the existing supply scene is also assessed. tabs., figs

  4. Pollution from pipelines

    International Nuclear Information System (INIS)

    1991-01-01

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

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

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

    2000-12-01

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

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

  13. The pipeline service obligation under changing LDC purchasing practices

    International Nuclear Information System (INIS)

    Neff, S.J.

    1990-01-01

    Historically, interstate natural gas pipelines served as aggregators and transporters of gas supplies from the producing fields to the city-gate. In turn, local distribution companies (LDCs) bought gas from pipelines at the city-gate under long-term sales contracts and resold the gas to retail customers. Once a pipeline/LDC sales relationship was established through a regulated certificate process, the LDC was assured of gas supply up to the level of its contract demand (CD) at just and reasonable rates until abandonment of the pipeline's sales service obligation was granted by the Federal Energy Regulatory Commission (FERC). During the years of regulated wellhead pricing and limited gas deliverability, pipelines signed long-term take-or-pay contracts with producers to induce them to develop and commit new gas supplies. Those supply cost obligations were reflected in tariff minimum bill provisions. For years, this pipeline/LDC arrangement was mutually beneficial and provided assured firm service. With the load diversity on large interstate pipeline systems and the make-up provisions under take-or-pay clauses, these gas purchase contracts provided supply reliability without negative economic consequence to the pipelines. Then, with the issuance of FERC Order Nos. 380, 436, and 500, LDCs' obligations to purchase gas from pipeline suppliers according to the terms of those long term sales agreements were irrevocably altered. The impacts of those long term sales agreements were irrevocably altered. The impacts of those orders the elimination of minimum bills and the advent of open access transportation caused a serious erosion of the mutual obligations between pipelines and their LDC customers. The result has been a significant loss of pipeline sales markets as LDC customers have chosen alternative supplied, often at the urging of state public utility commissions (PUCs) to lower short-term costs

    1978-01-01

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

    After the accidents happened on years 2000 and 2001, in TRANSPETRO's operated pipelines, appeared a common conscientiousness about the necessity for the creation of a basic infrastructure for emergency and contingency pipeline repair that centralize equipment, procedures and technologies applied to pipeline maintenance. Then, it was planned the creation of the On-Shore Pipeline Emergency Center (CRE-DUT), following the model of the Off-Shore Pipelines Repair Group from PETROBRAS/EP, (Exploration and Production) and other similar centers of pipeline transport companies worldwide (Canada, Colombia, Mexico, Argentina). The CRE-DUT has the Mission of offering contingency; emergency and specials on-shore pipelines repair services, with safety, quality and at the less possible time, seeking for the leadership on applying new technologies and the excellency in repair activities.

    1998-12-01

    The National Energy Board has requested the preparation of a comprehensive study report (CSR) for the proposed Halifax Lateral Pipeline Project in support of Maritimes and Northeast Pipeline Company's proposal to construct the lateral pipeline to transport natural gas produced in offshore Nova Scotia to the Tufts Cove electric generating station in the Halifax Regional Municipality. The project will also enhance the access of natural gas to potential markets located along the pipeline route. This CSR was prepared according to guidelines of the Canadian Environmental Assessment Agency. The report presents: (1) an overview of the project, (2) a summary of the regulatory requirements for assessment, (3) a description of the environmental assessment and regulatory process to date, (4) a summary of the predicted residual environmental and socio-economic effects associated with the project, and (5) a summary of the public consultation process. The environmental and socio-economic assessment focused on these eleven issues: groundwater resources, surface water resources, wetlands, soils, air quality, fish habitat, rare herpetiles, mammals, avifauna, rare plants and archaeological heritage resources. The report identified potential interactions between the project and valued socio-economic and environmental components. These were addressed in combination with recommended mitigative measures to reduce potential adverse effects. It was concluded that the overall environmental effects from the proposed project are likely to be minimal and can be effectively managed with good environmental management methods. 14 refs., 5 tabs., 5 figs., 2 appendices

    2008-01-01

    Twin oil (20 and 24 inch) and gas (20 and 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

    Providing effective protection for oil and gas pipelines is proving to be a difficult and expensive business, particularly in heavily used and environmentally sensitive waters such as the North Sea. The Danish Company Seditech has produced a design for ''hinged'' pipeline covers in concrete which are claimed to offer an effective solution to the problem. Model tests are currently (end of August 1977) being carried out at Trondheim, Norway, and this will be followed by a six-month feasibility study into the design of a suitable underwater installation vehicle. The aim is to produce total costs of the same order as pipe burial. The first step towards this has been achieved, as another Danish company has developed a combined vibration/pressure moulding system which allows individual cover elements to be produced in 3 to 5 min.

  1. LNG transport through pipelines

    Pfund, P; Philipps, A

    1975-01-01

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

    In the present invention, water levels of a feedwater heater and a drain tank in a nuclear power plant are detected at high accuracy. Detection pipeline headers connected to the upper and lower portions of a feedwater heater or a drain tank are connected with each other. The connection line is branched at appropriate two positions and an upper detection pipeline and a lower detection pipeline are connected thereto, and a gauge entrance valve is disposed to each of the detection pipelines. A diaphragm of a pressure difference generator is connected to a flange formed to the end portion. When detecting the change of water level in the feedwater heater or the drain tank as a change of pressure difference, gauge entrance valves on the exit side of the upper and lower detection pipelines are connected by a connection pipe. The gauge entrance valve is closed, a tube is connected to the lower detection pipe to inject water to the diaphragm of the pressure difference generator passing through the connection pipe thereby enabling to calibrate the pressure difference generator. The accuracy of the calibration of instruments is improved and workability thereof upon flange maintenance is also improved. (I.S.)

    Nowhere in Latin America has the privatization process been more aggressively pursued than in Argentina where President Carlos Menem has successfully turned over the bulk of state companies to the private sector. In the energy sector, that meant the divestiture in 1992 of Gas del Estado, the state-owned integrated gas transportation and distribution company. It was split in two transportation companies: Transportadora de Gas del Sur (TGS) and Transportadora de Gas del Norte (TGN), and eight distribution companies. TGS is the largest transporter of natural gas in Argentina, delivering more than 60 percent of that nation's total gas consumption with a capacity of 1.9 Bcf/d. This is the second in a series of Pipeline and Gas Journal special reports that discuss the evolving strategies of the natural gas industry as it continues to restructure amid deregulation. The article focuses on TGS, the Argentine pipeline system in which Enron Corp. is a key participant

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

    An operator faced with an onshore pipeline that has extensive damage must consider the need for rehabilitation, the sort of rehabilitation to be used, and the rehabilitation schedule. This paper will consider pipeline rehabilitation based on the authors' experiences from recent projects, and recommend a simple strategy for planning pipeline rehabilitation. It will also consider rehabilitation options: external re-coating; internal lining; internal painting; programmed repairs. The main focus will be external re-coating. Consideration will be given to rehabilitation coating types, including tape wraps, epoxy, and polyurethane. Finally it will discuss different options for scheduling the rehabilitation of corrosion damage including: the statistical comparison of signals from inspection pigs; statistical comparison of selected measurements from inspection pigs and other inspections; the use of corrosion rates estimated for the mechanisms and conditions; expert judgement.

    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).

    The sustainability of Social and Environmental programs along pipelines, have shown to be a major challenge. Gas pipelines in Bolivia and Brazil operate in a diversity of environments and communities with different cultures, values and expectations. However, the pipeline network can also provide opportunities for contributing to regional development and working with local populations on topics of mutual interest. Many of these are quite strategic because they arise from topics of mutual interest for both the company and neighboring populations, and because they provide opportunities for achieving results of mutual benefit. These opportunities could include helping to make gas available to local communities, contributions to urban planning, hiring local services and other initiatives. Sustainable and integrated Social and Environmental programs are therefore key to a successful pipeline operation. These opportunities are often missed or under valued. Some successful examples are presented from Transredes S.A., Bolivia. (author)

  12. Northern pipelines : backgrounder

    International Nuclear Information System (INIS)

    2002-04-01

    Most analysts agree that demand for natural gas in North America will continue to grow. Favourable market conditions created by rising demand and declining production have sparked renewed interest in northern natural gas development. The 2002 Annual Energy Outlook forecasted U.S. consumption to increase at an annual average rate of 2 per cent from 22.8 trillion cubic feet to 33.8 TCF by 2020, mostly due to rapid growth in demand for electric power generation. Natural gas prices are also expected to increase at an annual average rate of 1.6 per cent, reaching $3.26 per thousand cubic feet in 2020. There are currently 3 proposals for pipelines to move northern gas to US markets. They include a stand-alone Mackenzie Delta Project, the Alaska Highway Pipeline Project, and an offshore route that would combine Alaskan and Canadian gas in a pipeline across the floor of the Beaufort Sea. Current market conditions and demand suggest that the projects are not mutually exclusive, but complimentary. The factors that differentiate northern pipeline proposals are reserves, preparedness for market, costs, engineering, and environmental differences. Canada has affirmed its role to provide the regulatory and fiscal certainty needed by industry to make investment decisions. The Government of the Yukon does not believe that the Alaska Highway Project will shut in Mackenzie Delta gas, but will instead pave the way for development of a new northern natural gas industry. The Alaska Highway Pipeline Project will bring significant benefits for the Yukon, the Northwest Territories and the rest of Canada. Unresolved land claims are one of the challenges that has to be addressed for both Yukon and the Northwest Territories, as the proposed Alaska Highway Pipeline will travel through traditional territories of several Yukon first Nations. 1 tab., 4 figs

  13. Pipeline protection with multi component liquid polyurethane coating systems

    Protective coating systems are one of the major defence mechanisms against corrosion for transmission pipelines, pipes within a refinery or petrochemical processing facilities. More and more pipelines are being constructed for the supply and transmission of gas and oil, each year but, in addition many existing pipelines are approaching an age where inspection reveals the necessity to consider complete refurbishment. However, the number of rehabilitation projects each year is still relatively small. Therefore, in the coming years, a rising need and necessity can be expected, for the owners and operating companies to be faced with the option of either replacing the pipeline or refurbishing of the existing pipeline. If the pipeline is known to have external corrosion, then safe and economic operation should be assured. Rehabilitation should be done before it is too late in order to ensure its future integrity and operational life. Rehabilitation of pipelines has been both the economic solution and, more significantly, the ecological solution and in many of those cases the coatings selected for the external protection has been multi component liquids based on 100% solids polyurethanes.

    This paper describes the potential economic impact and benefits to Alberta from the proposed development of the Alaska Highway Pipeline (AHP) and the Mackenzie Valley Pipeline (MVP). It also includes a planning framework for business and industry in the province. Each proposed pipeline was evaluated separately. The paper includes a list of Alberta companies that stand to benefit from the construction of one or both pipelines. The main findings indicate that northern pipeline development will bring opportunities to Alberta business in design, construction and management. There will be a secondary impact on petrochemical industries and infrastructure. Both pipeline developments will increase employment and yield billions of dollars in gross domestic product. The existing oil and gas industry in Alberta will receive value-added opportunities in areas of specialized expertise such as natural gas and natural gas liquid storage, natural gas liquid processing, and gas to liquid technology projects. The industry will also benefit from power generation and cogeneration. The northern pipelines have the potential to improve the role of First Nations in economic development. Gas consumers in Alberta should benefit from a secure supply of gas and lower prices. refs., tabs., figs

    Many times a year natural gas transmission and distribution companies need to make new connections to pipelines to expand or modify their existing system through hot tapping procedure. This procedure involves the installation of a new pipeline connection while the pipeline remains in service, flowing natural gas under pressure. The hot tap procedure includes attaching a branch connection and valve on the outside of an operating pipeline, and then cutting out the pipe-line wall within the branch and removing the wall section, which is called object of coupon through the valve. During the hot tapping process a critical problems occurred when a coupon fell into the mother pipeline. To overcome this problem, a gamma-ray absorption technique was chosen whereby a mapping technique will be done to detect the coupon position. The technique is non-destructive as it applies Co-60 (5 mCi) as a radioisotope sealed source to emit gamma radiation and a NaI(Tl) scintillation as detector. The result provided a visible representation of density profile inside pipeline where the coupon location can be located. This paper provides the detail of the technique used and presents the result obtained. (author)

    This paper reports that North American pipelines and utilities will spend more than $170 million on new or upgraded supervisory control and data acquisition (scada) systems during the 30-month period that commenced Sept. 1. Another $12.5 million will be spent on peripherals and consulting. Among the 699 various projects to be implemented during the period, companies will install 151 scada systems, add 154 remote-terminal units (RTUs) to existing scada units, and install 196 communications systems. Scada systems are computerized hardware and software systems that perform a set of monitoring and control functions. In gas utilities, these systems perform functions normally associated with gas transmission and distribution as well as production plant process control. In gas and oil pipelines, the systems perform these functions as well as such specialized functions as batch tracking, leak detection, and gas load flow

    The Caspian Pipeline Consortium (CPC), a shipper-owned oil pipeline carrying Caspian oil to Russia's Black Sea port of Novorossyisk, remains to this day the only oil export pipeline on Russian territory that is not under the control of the state company Transneft. Completed in 2001, the CPC was, from the start, the product of a fragile balance of power between states eager to maintain control of hydrocarbon flows and private companies able to finance the necessary infrastructure. Despite its economic success, the future of the CPC currently hinges on a share-holding dispute pitting Russia against private shareholders. This essay places the CPC dossier in the broader context of Russia's investment climate and argues that the dispute's dynamic is an important bellwether of the Russian energy policy. (author)

    Deliverability on the Interstate Natural Gas Pipeline System examines the capability of the national pipeline grid to transport natural gas to various US markets. The report quantifies the capacity levels and utilization rates of major interstate pipeline companies in 1996 and the changes since 1990, as well as changes in markets and end-use consumption patterns. It also discusses the effects of proposed capacity expansions on capacity levels. The report consists of five chapters, several appendices, and a glossary. Chapter 1 discusses some of the operational and regulatory features of the US interstate pipeline system and how they affect overall system design, system utilization, and capacity expansions. Chapter 2 looks at how the exploration, development, and production of natural gas within North America is linked to the national pipeline grid. Chapter 3 examines the capability of the interstate natural gas pipeline network to link production areas to market areas, on the basis of capacity and usage levels along 10 corridors. The chapter also examines capacity expansions that have occurred since 1990 along each corridor and the potential impact of proposed new capacity. Chapter 4 discusses the last step in the transportation chain, that is, deliverability to the ultimate end user. Flow patterns into and out of each market region are discussed, as well as the movement of natural gas between States in each region. Chapter 5 examines how shippers reserve interstate pipeline capacity in the current transportation marketplace and how pipeline companies are handling the secondary market for short-term unused capacity. Four appendices provide supporting data and additional detail on the methodology used to estimate capacity. 32 figs., 15 tabs.

    This paper presents the experience acquired by PETROBRAS Transporte S.A., TRANSPETRO, signaling the crossing of Sao Paulo - Brasilia Pipeline, OSBRA, with the Grande River, important brazilian river that has in this cross section 400 m in width and 10 m of average depth. In sub aquatic inspections carried through by divers to confirm the pipeline's silting condition, evidences of basin format dredging near the pipeline have been identified and, even though it was not sufficient to expose de pipeline, has reduced its covering significantly. This site is an important area of sand extraction, and although the intense works of awareness of local dredging companies to not operate in the pipeline area, TRANSPETRO was surprised by the evidences. In testimonials, local dredge operators complained about difficulties in identifying the pipeline position in nightly operations. Expecting to improve the operational security in the pipeline crossing, a joint project was developed by TRANSPETRO, Brazilian Navy and the dredging companies, with the intention to signal safe area around the submerged pipeline, avoiding dredge operations with the installation of polyethylene floating buoys equipped with night signaling kits and fixed by concrete anchors. Although it was technically simple, the unprecedented proposal in Brazil increased safety in the pipeline operations and made them much safer for the local population and for the environment, in one of the biggest water resources of the Southeastern region of Brazil.

    Energy and Pipeline Companies wrestle to control operating costs largely affected by new government regulations, ageing buried metal assets, rising steel prices, expanding pipeline operations, new interference points, HCA encroachment, restrictive land use policies, heightened network security, and an ageing soon-to-retire work force. With operating costs on the rise, seemingly out of control, many CP and Operations Professionals look to past best practices in cost containment through automation. Many companies achieve solid business results through deployment of telemetry and SCADA automation of remote assets and now hope to expand this success to further optimize operations by automating remote cathodic protection systems. This presentation will provide examples of how new remote cathodic protection systems are helping energy and pipeline companies address the growing issue of the aging pipeline infrastructure and reduce their costs while optimizing their operations.

    This paper presents preliminary findings from six vegetational surveys of gas pipeline rights-of-way (ROW) through wetlands and quantifies the impacts of a 20-year-old pipeline ROW through a boreal forest wetland. Six sites of various ages were surveyed in ecosystems ranging from coastal marsh to forested wetland. At all sites except one, both the number and the percentage of wetland species on the Row approximated or exceeded those in the adjacent natural area. The boreal forest study showed that (1) adjacent natural wetland areas were not altered in type; (2) water sheet flow restriction had been reversed by nature; (3) no nonnative plant species invaded the natural area; (4) three-quarters of the ROW area was a wetland, and (5) the ROW increased diversity

    Central Florida Pipeline Company (CFPL), a subsidiary of GATX Terminals Corp., Tampa, FL, has used directional drilling under seven water bodies in Hillsborough, Polk and Osceola Counties in constructing its new pipeline from Tampa to Orlando. Primary reason for using directional drilling is to protect the environment by minimizing water turbidity while the 16-inch diameter, 109-mile refined petroleum products pipeline is being installed. Total cost of the project is pegged at $68.5 million. Directional drilling enabled the pipe to be placed about 20 feet below the bottom of: The Alafia River in Riverview with 999 feet drilled; Port Sutton Channel near the Port of Tampa with 2,756 feet drilled; Reedy Creek Swamp at the intersection of Interstate 4 and Highway 192 which had 1,111 feet drilled; Wetland number-sign 70 southwest of Lake Wales with 1,575 feet drilled; Peace River south of Bartow had 2,470 feet drilled; Bonnet Creek west of Kissimmee had 693 feet drilled.

    2006-07-01

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

    Pipeline safety in the United States has increased in recent decades, but incidents involving natural gas pipelines still cause an average of 17 fatalities and $133 M in property damage annually. Natural gas leaks are also the largest anthropogenic source of the greenhouse gas methane (CH4) in the U.S. To reduce pipeline leakage and increase consumer safety, we deployed a Picarro G2301 Cavity Ring-Down Spectrometer in a car, mapping 5893 natural gas leaks (2.5 to 88.6 ppm CH4) across 1500 road miles of Washington, DC. The δ(13)C-isotopic signatures of the methane (-38.2‰ ± 3.9‰ s.d.) and ethane (-36.5 ± 1.1 s.d.) and the CH4:C2H6 ratios (25.5 ± 8.9 s.d.) closely matched the pipeline gas (-39.0‰ and -36.2‰ for methane and ethane; 19.0 for CH4/C2H6). Emissions from four street leaks ranged from 9200 to 38,200 L CH4 day(-1) each, comparable to natural gas used by 1.7 to 7.0 homes, respectively. At 19 tested locations, 12 potentially explosive (Grade 1) methane concentrations of 50,000 to 500,000 ppm were detected in manholes. Financial incentives and targeted programs among companies, public utility commissions, and scientists to reduce leaks and replace old cast-iron pipes will improve consumer safety and air quality, save money, and lower greenhouse gas emissions.

    VNIIgaz has improved the conventional Japanese SECT pipeline-heating system, which uses a small steel tube that contains an insulated heater/conductor and is welded to the top of the pipeline. The improved version has two insulated electric heaters - one on the top and the other on the bottom of the pipeline - located inside steel angle irons that are welded to the pipeline. A comparison of experimental results from heating a 200-ft pipeline with both systems at currents of up to 470 A clearly demonstrated the better heating efficiency of the VNIIgaz unit. The improved SECT system would be suitable for various types of pipelines, including gas lines, in the USSR's far north regions.

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

    Lima, Marco Aurelio [Det Norske Veritas (DNV), Rio de Janeiro, RJ (Brazil)

    2008-07-01

    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.

    The need to easily access pipeline information and the increasing number of inspections using distinct techniques from different vendors makes the use of systems in the Integrity Management Program indispensable. For this reason, MOPI has been developed by two Brazilian companies, Pipeway Engenharia in partnership with Minds at Work. This tool allows data recording from the design, construction and operation of the pipeline, the storage of documents, the comparison between the results of different inspections, the planning inspections, contracts and maintenance of the pipeline. Furthermore, the information registered in the system can be accessed by a network user without limitation of time or number of users. This work presents the main details and features of MOPI.

    International Nuclear Information System (INIS)

    Wirick, J.

    2001-01-01

    The existing interstate pipelines and proposed pipeline projects for the Chicago hub area were illustrated. The presentation explained why energy suppliers in the current competitive market need to balance and manage energy and transportation services for gas-fired power generators in terms of hourly winter and summer peaking services. The new infrastructure of the energy market will include new pipelines, storage and balancing to meet the ever increasing power demand. One of the options to meet power demand is to increase natural gas supply, transportation, storage, and hourly balancing capabilities. Other options are to build nuclear or coal-fired power generating facilities, or to go with renewables such as solar and wind power. Energy conservation and the reduction of natural gas usage per capita is another option to eliminate blackouts. This presentation also addressed the role that local distribution companies (LDC) and unbundling will play in the choice of these options. tabs., figs

  15. Alaska-Canada Pipeline Project : getting it done

    Energy Technology Data Exchange (ETDEWEB)

    Brintnell, R. [Enbridge Pipelines Inc., Calgary, AB (Canada)

    2005-07-01

    Enbridge's unique qualifications for the proposed Alaska-Canada pipeline that will extend from Prudhoe Bay, Alaska to Fort Saskatchewan, Alberta was discussed. Enbridge is Canada's largest local distribution company (LDC), handling approximately 14 bcf of natural gas per day through pipeline, processing and marketing. It also operates the world's longest liquids pipeline, delivering more than 2 million barrels per day. The company also has 20 years of operational experience in perma frost regions. The key challenges facing the construction of the proposed new high pressure liquids rich pipeline were discussed with reference to market outlook; cost reduction; U.S. fiscal and regulatory issues; Alaska fiscal contract; and, Canadian regulatory efficiency. A successful project will mean a $15 billion capital expenditure in Canada, $16 billion in government revenues, 12,000 construction work years, and tens of thousands of new jobs. It will also improve Alberta's position as the key energy hub and will increase the utilization of the existing infrastructure. Canadian consumers will benefit from access to a new supply basin and a more secure source of clean-burning natural gas at a cost competitive price. In order to get the project completed, the following requirements must be met: regulatory regimes must be clear and predictable; land access must be ensured in a timely manner; access to skilled human resources, material and equipment must also be ensured to facilitate timely and efficient project implementation; and, the safe and environmentally sound operation of the pipelines must also be ensured. This paper highlighted Canadian regulatory options in terms of the National Energy Board Act, Canadian Environmental Assessment Act, the Yukon Environmental and Socio-Economic Assessment Act, and the Northern Pipeline Act. Enbridge's proposed straddle plant at Fort Saskatchewan was discussed along with inter-connecting pipeline options. Enbridge

  16. Planning international transit oil pipeline projects in Croatia

    International Nuclear Information System (INIS)

    Sekulic, G.; Vrbic, D.

    2004-01-01

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

  17. Pipeline Processing for VISTA

    Lewis, J. R.; Irwin, M.; Bunclark, P.

    2010-12-01

    The VISTA telescope is a 4 metre instrument which has recently been commissioned at Paranal, Chile. Equipped with an infrared camera, 16 2Kx2K Raytheon detectors and a 1.7 square degree field of view, VISTA represents a huge leap in infrared survey capability in the southern hemisphere. Pipeline processing of IR data is far more technically challenging than for optical data. IR detectors are inherently more unstable, while the sky emission is over 100 times brighter than most objects of interest, and varies in a complex spatial and temporal manner. To compensate for this, exposure times are kept short, leading to high nightly data rates. VISTA is expected to generate an average of 250 GB of data per night over the next 5-10 years, which far exceeds the current total data rate of all 8m-class telescopes. In this presentation we discuss the pipelines that have been developed to deal with IR imaging data from VISTA and discuss the primary issues involved in an end-to-end system capable of: robustly removing instrument and night sky signatures; monitoring data quality and system integrity; providing astrometric and photometric calibration; and generating photon noise-limited images and science-ready astronomical catalogues.

    1997-01-01

    Some of the new major pipeline projects that will bring Canadian gas into Chicago and the United States northeastern market were described. The seven projects discussed were: Independence Pipeline Company, Columbia's Millennium Project, Alliance Pipeline, Viking Voyageur, Pan Energy's Spectrum, Tennessee's Eastern Express, and National Fuel Expansion. The need for all this new capacity was questioned. The US FERC Commissioners are willing to let the market decide the need for this capacity. It was noted that the serious regulatory issues pipelines will face lie in the radically different rate treatment for pipelines, depending on the support the market shows for their respective projects. Various past decisions of the Federal Energy Regulatory Commission (FERC) were reviewed to illustrate the direction of the Commission's thinking in terms of regulatory approval, and to examine the question of whether FERC's approval policy makes good sense. The author's view is that the 'at risk' conditions of approval, coupled with incremental rate treatment by the Commission does, in fact, provide protection for consumers

  4. Optimal Energy Consumption Analysis of Natural Gas Pipeline

    Science.gov (United States)

    Liu, Enbin; Li, Changjun; Yang, Yi

    2014-01-01

    There are many compressor stations along long-distance natural gas pipelines. Natural gas can be transported using different boot programs and import pressures, combined with temperature control parameters. Moreover, different transport methods have correspondingly different energy consumptions. At present, the operating parameters of many pipelines are determined empirically by dispatchers, resulting in high energy consumption. This practice does not abide by energy reduction policies. Therefore, based on a full understanding of the actual needs of pipeline companies, we introduce production unit consumption indicators to establish an objective function for achieving the goal of lowering energy consumption. By using a dynamic programming method for solving the model and preparing calculation software, we can ensure that the solution process is quick and efficient. Using established optimization methods, we analyzed the energy savings for the XQ gas pipeline. By optimizing the boot program, the import station pressure, and the temperature parameters, we achieved the optimal energy consumption. By comparison with the measured energy consumption, the pipeline now has the potential to reduce energy consumption by 11 to 16 percent. PMID:24955410

    1998-12-31

    This paper is the press release of the talk given at the `Gaz de France scientific meeting with the press` by P. Gadonneix, chairman of Gaz de France company, on October 7, 1998. The aim of this talk concerns the new French and European supply link for bringing natural gas from the Norwegian North Sea fields. This new supply link is the first direct link between Norway and France and the NorFra gas pipeline which brings natural gas from the North Sea to France is the longest offshore pipeline in the world. The `Artere des Hauts de France` pipeline (the largest diameter gas pipeline ever laid in France) is devoted to the transfer of natural gas from Dunkerque to the Gournay-sur-Aronde underground storage site. This paper describes successively: the French European gas supply hub, the NorFra project, the Artere des Hauts de France pipeline, the network performance research, the safety and quality guaranties, the reduction of overland natural gas transmission costs (improvement of pipe-laying techniques and optimization of line route and welding operations), the specific techniques used for road and river crossing (micro-tunnel digging, river-crossing ditches) and for anchoring (buoyancy compensation). Finally, the environmental impact of the laying operations is briefly described. (J.S.)

  6. Microcap pharmaceutical firms: linking drug pipelines to market value.

    Science.gov (United States)

    Beach, Robert

    2012-01-01

    This article examines predictors of the future market value of microcap pharmaceutical companies. This is problematic since the large majority of these firms seldom report positive net income. Their value comes from the potential of a liquidity event such as occurs when a key drug is approved by the FDA. The typical scenario is one in which the company is either acquired by a larger pharmaceutical firm or enters into a joint venture with another pharmaceutical firm. Binary logistic regression is used to determine the impact of the firm's drug treatment pipeline and its investment in research and development on the firm's market cap. Using annual financial data from 2007 through 2010, this study finds that the status of the firm's drug treatment pipeline and its research and development expenses are significant predictors of the firm's future stock value relative to other microcap pharmaceutical firms.

  7. An integrated approach to route selection in slurry pipeline design

    Energy Technology Data Exchange (ETDEWEB)

    Betinol, Roy G.; Altmann, Nara [Brass Chile S.A., Santiago (Chile)

    2009-12-19

    The pressure to get engineering projects done and constructed as fast as possible in order to take advantage of the high prices in metals and petrochemicals has been driving companies to skip the conceptual phase and go straight into basic engineering with cost estimates in the level of 15% accuracy. By-passing early engineering and demanding higher cost estimating accuracy is a contradiction. In most cases, savings made on capital investment is much higher had money been spent in conceptual studies which allow for the optimal solution to be found. This paper reviews one of the key aspects in conceptual engineering of slurry pipeline designs: route selection. This activity is often overlooked, causing capital cost and operating difficulties to rise unnecessarily. This paper describes and gives example on how an integrated client/engineering company's approach to route selection can produce significant savings in pipeline construction and operating costs.

  8. Viability of using different types of main oil pipelines pump drives

    Science.gov (United States)

    Zakirzakov, A. G.; Zemenkov, Yu D.; Akulov, K. A.

    2018-05-01

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

    Knolle, Ernst G.

    1994-01-01

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

  14. Should the Nabucco pipeline project be shelved?

    International Nuclear Information System (INIS)

    Barysch, K.

    2010-05-01

    It is easy to be pessimistic about the prospects of Nabucco, a pipeline designed to bring Caspian and possibly Middle Eastern gas to the EU. The financing is not yet secure, European gas demand is down, and the question of where Nabucco's gas will come from is open. Russia, meanwhile, is pushing hard for its rival South Stream pipeline. Nabucco would be good for the EU in various ways. It would make Central and East European countries a lot less dependent on Gazprom and increase the energy security of the EU as a whole. It could help reduce intra-EU divisions over Russia. It would underpin stronger ties between the EU and potential supplier countries such as Azerbaijan and Turkmenistan. It could help improve EU-Turkey relations. Many of the benefits that Nabucco would bring do not accrue to the companies that are trying to build it or the banks that lend the money for it. Therefore, the EU and its governments should back Nabucco more strongly, both politically and financially.

  15. Thermoplastic liners for carbon steel pipelines

    Energy Technology Data Exchange (ETDEWEB)

    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)

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

    The geomagnetic fluctuations are accompanied by geo-electric (telluric) field and telluric currents at the surface of the Earth and in the pipelines. These currents interfere with pipeline corrosion protection, creating pipe-to-soil potential (PSP) fluctuations. It impacts pipeline operations in two ways. One is that non-disturbed "true" level of the protection is not known, which might lead to the wrong conclusions that a pipeline coating is damaged and digging out the section of the pipeline is needed. The other effect is changes in the electrical conditions in the pipeline-soil interface, compromising the corrosion protection and possibly causing enhancement of the corrosion. The global trend for construction of more pipelines in northern regions means placing them into areas where natural geomagnetic variations are larger and consequently telluric activity is more extreme, in comparison with pipelines located further south. This paper describes the solutions implemented as the result of the two projects done by NRCan researchers led by the author on request from pipeline companies. Two methods were proposed and implemented to address the problems. One is the statistical estimation of the telluric activity in the area of the planned pipelines. These statistical considerations then used as guidance in the design of corrosion protection systems to counteract the excessive corrosion. The other, to deal with the corrupted results during the pipeline surveys, is to forecast the geomagnetic storms for proper planning of the surveys. In addition, the developed telluric activity identification tool can be used in the analysis of the corrupted survey data.

  6. Optimal valve location in long oil pipelines

    OpenAIRE

    Grigoriev, A.; Grigorieva, N.V.

    2007-01-01

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

  7. Pipeline for Contraceptive Development

    2016-01-01

    The high rates of unplanned pregnancy reflect unmet need for effective contraceptive methods for women, especially for individuals with health risks such as obesity, diabetes, hypertension, and other conditions that may contraindicate use of an estrogen-containing product. Improvements in safety, user convenience, acceptability and availability of products remain important goals of the contraceptive development program. Another important goal is to minimize the impact of the products on the environment. Development of new methods for male contraception has the potential to address many of these issues with regard to safety for women who have contraindications to effective contraceptive methods but want to protect against pregnancy. It also will address a huge unmet need for men who want to control their fertility. Products under development for men would not introduce eco-toxic hormones in the waste water. Investment in contraceptive research to identify new products for women has been limited in the pharmaceutical industry relative to investment in drug development for other indications. Pharmaceutical R&D for male contraception was active in the 1990’s but was abandoned over a decade ago. The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) has supported a contraceptive development program since 1969. Through a variety of programs including research grants and contracts, NICHD has developed a pipeline of new targets/products for male and female contraception. A number of lead candidates are under evaluation in the NICHD Contraceptive Clinical Trials Network (CCTN) (1–3). PMID:27523300

  8. Crude oil pipeline expansion summary

    International Nuclear Information System (INIS)

    2005-02-01

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

  9. Solving an unpiggable pipeline challenge

    2009-07-01

    Technically, any pipeline can be retrofitted to enable in line inspection. Sensibly however, the expense of excavations and construction of permanent facilities have been, in many cases, exceedingly prohibitive. Even where traditional modifications are feasible from engineering perspectives, flow interruption may not be an option - either because they are critical supply lines or because the associated lost revenues could be nearly insurmountable. Savvy pipeline integrity managers know the safety issue that is at stake over the long term. They are also well aware of the accuracy benefits that high-quality in-line inspection data offer over potentially supply disruptive alternatives such as hydrostatic testing. To complicate matters further, many operators, particularly in the US, now face regulatory pressure to assess the integrity of their yet-uninspected pipelines located in highly populated areas. This paper describes an important project National Grid undertook that made use of a unique pipeline access method that did not require permanent installation of expensive facilities required for in line inspection of a pipeline previously considered 'unpiggable'. Since the pipeline was located in an urban area, flow disruption had to be minimized. This paper will define the project background, its challenges, outcomes and lessons learned for the future.

    The X-rays diffraction technique is a well established and effectiveness method in the determination of the residual and applied stresses in fine grained crystalline materials. It allows to characterize and to quantify the magnitude and direction of the existing surface stresses in the studied point of the material. The objective of this work is the evaluation of the surface stresses in a 10 in diameter Natural Gas Distribution Pipeline manufactured from API 5 L Gr B steel of COMPAGAS company, in a crossing with a Natural Gas Transportation Pipeline, in Araucaria-PR. This kind of evaluation is important to establish weather you have to perform a repositioning of one of the pipeline or not. The measurements had been made in two transversal sections of the pipe, the one upstream (170 mm of the external wall of the pipeline) and another one downstream (840 mm of the external wall of the pipeline). Each transversal section measurements where carried out in 3 points: 9 hours, 12 hours and 3 hours. In each measured point of the pipe surface, the longitudinal and transversal stresses had been measured. The magnitude of the surface residual stresses in the pipe varied of +180 MPa at the -210 MPa. The residual stress state on the surface of the points 12 hours region is characterized by tensile stresses and by compressive stresses in the points of 3 and 9 hours region. The surface residual stresses in gas-pipeline have been measured using X-ray diffraction method, by double exposure technique, using a portable apparatus, with Cr-K-alpha radiation. (author)

  14. Gathering pipeline methane emissions in Fayetteville shale pipelines and scoping guidelines for future pipeline measurement campaigns

    Directory of Open Access Journals (Sweden)

    Daniel J. Zimmerle

    2017-11-01

    Full Text Available Gathering pipelines, which transport gas from well pads to downstream processing, are a sector of the natural gas supply chain for which little measured methane emissions data are available. This study performed leak detection and measurement on 96 km of gathering pipeline and the associated 56 pigging facilities and 39 block valves. The study found one underground leak accounting for 83% (4.0 kg CH4/hr of total measured emissions. Methane emissions for the 4684 km of gathering pipeline in the study area were estimated at 402 kg CH4/hr [95 to 1065 kg CH4/hr, 95% CI], or 1% [0.2% to 2.6%] of all methane emissions measured during a prior aircraft study of the same area. Emissions estimated by this study fall within the uncertainty range of emissions estimated using emission factors from EPA’s 2015 Greenhouse Inventory and study activity estimates. While EPA’s current inventory is based upon emission factors from distribution mains measured in the 1990s, this study indicates that using emission factors from more recent distribution studies could significantly underestimate emissions from gathering pipelines. To guide broader studies of pipeline emissions, we also estimate the fraction of the pipeline length within a basin that must be measured to constrain uncertainty of pipeline emissions estimates to within 1% of total basin emissions. The study provides both substantial insight into the mix of emission sources and guidance for future gathering pipeline studies, but since measurements were made in a single basin, the results are not sufficiently representative to provide methane emission factors at the regional or national level.

  15. Pipeline investigation report : crude oil pipeline-third party damage : Trans Mountain Pipeline LP 610 millimetre-diameter crude oil pipeline : kilometre post 3.10, Westridge dock transfer line, Burnaby, British Columbia

    International Nuclear Information System (INIS)

    2009-03-01

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

  17. Report of study group 4.3 ''pipeline integrity management and safety''

    Energy Technology Data Exchange (ETDEWEB)

    Clavel, P.

    2000-07-01

    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,...).

  18. Natural gas pipelines: emerging market challenges

    International Nuclear Information System (INIS)

    Smart, A.; Balfe, P

    2001-01-01

    The Australian gas industry has come a long way in recent years. Most of the formerly government owned gas transmission, distribution and retail businesses have been privatised; major utility companies have been fundamentally restructured; the convergence of energy markets has seen many companies stepping outside the boundaries of their traditional businesses; and national competition policy has led to profound changes in the regulatory landscape. Yet despite the magnitude of these changes, it is clear that the journey of competitive reform has a long way to go. The Australian Gas Association's Industry Development Strategy identifies the potential for gas to increase its share of Australia's primary energy market, from around 18 percent at present to 22 percent by 2005, and 28 percent by 2015. Our analysis, using ACIL's Eastern Australian Gas Model, clearly shows that in the absence of major new sources of gas, these challenging targets will not be met and, indeed, there will be an increasing supply shortfall. However, with the emergence of new competitive supply sources such as Papua New Guinea and the Timor Sea, our modelling suggests that most of this demand can be satisfied at prices which will maintain gas' competitiveness in energy markets. Such developments provide both opportunities and challenges for the industry. In particular, they will profoundly affect the owners and operators of transmission pipeline systems. (Authors)

  19. New territory for NGL pipelines

    International Nuclear Information System (INIS)

    Turner, C.L.; Billings, F.E.

    1994-01-01

    Even though the NGL pipeline industry appears mature, new geographic territory exists for expansion of NGL pipelines. However, the most fertile territory that must be pursued is the collective opportunities to better link the existing NGL industry. Associations like the Gas Processors Association can not perform the role demanded by a need to share information between the links of the chain on a more real time basis. The Association can not substitute for picking up the phone or calling a meeting of industry participants to discuss proposed changes in policies and procedures. All stakeholders must participate in squeezing out the inefficiencies of the industry. Some expansion and extension of NGL pipelines will occur in the future without ownership participation or commitments from the supply and demand businesses. However, significant expansions linking new supply sources and demand markets will only be made as the supply and demand businesses share long-term strategies and help define the pipeline opportunity. The successful industries of the twenty-first century will not be dominated by a single profitable sector, but rather by those industries which foster cooperation as well as competition. A healthy NGL industry will be comprised of profitable supply businesses and profitable demand businesses, linked together by profitable pipeline businesses

  20. Environmental, public health, and safety assessment of fuel pipelines and other freight transportation modes

    International Nuclear Information System (INIS)

    Strogen, Bret; Bell, Kendon; Breunig, Hanna; Zilberman, David

    2016-01-01

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

  1. Innovations in optimizing mitigation and pipeline risk management for natural gas and hazardous liquid systems

    Gloven, Michael P; Hendren, Elaine S; Zeller, Sherri A; Ramirez, Pete V [Bass-Trigon (United States)

    2003-07-01

    Pipeline risk management has been stimulated by pipeline ruptures throughout the world. This paper explores risk management and mitigation strategies for minimizing consequences from pipeline releases, and optimizing financial resources in response or in prevention of these events. More specifically, it examines private sector innovations which optimize mitigation activities in combination with public sector programs such as regulations and standards (i.e., ASME B31.S, API 1160). The mitigation of risk involves the implementation of measures to reduce the frequency of failure, the severity of consequences, or both these attributes of risk. A wide variety of risk mitigation measures are available to pipeline operators. Given the diversity of mitigation measures available, this paper proposes a framework that can assist operating companies in selecting risk mitigation strategies based on risk results, mitigation costs and benefits.

  2. Use of GRASS for routing gas pipeline rights-of-way

    International Nuclear Information System (INIS)

    Sydelko, P.J.

    1992-01-01

    This study, sponsored by the Gas Research Institute (GRI), was conducted to illustrate how a GIS (Geographic Information System) can be used to assess alternative routes for new gas pipeline rights-of-way (ROWs). The results show that a least-cost analysis using GRASS (Geographic Resources Analysis and Support System) is a good method for siting new gas pipeline ROWs on the basis of environmental and engineering constraints to pipeline construction and maintenance. The cost and time needed to use this least-cost approach compare favorably with the current methods used by gas pipeline company planners and engineers. The types of criteria used, as well as the costs or weights given to the criteria, can be changed easily. This provides the flexibility to assess several alternatives quickly and easily

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

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

    There are many earthquakes in Japan. If a large earthquake were to occur, it is necessary to consider how pipelines such as: gas, sewage, telecommunications, and so on are restored quickly. At that time, damaged gas pipelines are very dangerous because fire in large areas could be caused by the leakage of gas from the damaged pipeline. Accordingly, it is necessary for gas companies to stop the supply of gas to houses over a large area. Once the gas supply is stopped, there is a considerable a...

    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.

    Some new pipelines undertakings aim to establish connection between gas provinces in the Southeast and consumers in the Northeast of Brazil, in order to supply medium consuming centers and regions with minor potential of development. Consulting companies are carrying out Environmental Assessments studies and among them is the Risk Analyses of these pipeline transmission systems, in order to receive environmental permits by IBAMA, the Federal Brazilian Environmental Agency. In addition, existing interstate pipeline systems which are under IBAMA regulation will also require the same attention. For the purpose of defining a Pipeline Risk Analysis Protocol with methodology and risk criteria, with minimum risk analysis information on a comprehensive process, it has been decided for a 'tour de force' formed by experts from IBAMA and PETROBRAS engineers. The risk assessment protocol is focus on the risk to communities in the neighborhood of these pipelines and on the potential damage to the environment near and far from the ROW. The joined work ended up in two protocols, which attempt to provide environmental license permits for oil pipeline and gas pipelines with minimum contents for risk analysis studies. Another aspect is the environmental risk that has been focused on the contingency plan approach, since there are no consolidated environmental risk criteria for application as a common worldwide sense. The environmental risk mapping - MARA methodology will indicate areas with potential to be affected by leakages along a pipeline system. (author)

    1977-01-01

    Purpose: To enable effective operation for the gas centrifuge cascade system upon failures in the system not by interrupting the operation of all of the centrifuges in the system but by excluding only the failed centrifuges. Constitution: A plurality of gas centrifuges are connected by way of a pipeline and an abnormal detector for the automatic detection of abnormality such as destruction in a vacuum barrel and loss of vacuum is provided to each of the centrifuges. Bypass lines for short-circuitting adjacent centrifuges are provided in the pipelines connecting the centrifuges. Upon generation of abnormality in a centrifuge, a valve disposed in the corresponding bypass is automatically closed or opened by a signal from the abnormal detector to change the gas flow to thereby exclude the centrifuge in abnormality out of the system. This enables to effectively operate the system without interrupting the operation for the entire system. (Moriyama, K.)

    1990-01-01

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

    In this work the quantitative risks analysis to the external public of the Pipeline Cabiunas - REDUC (GASDUC III), with 180 km, linking the municipalities of Macae and Duque de Caxias - RJ was performed by the Companies PETROBRAS and ITSEMAP do Brasil. In addition to the large diameter of the pipeline 38 inches and high operation pressure 100 kgf/cm{sup 2} operating with natural gas through several densely populated areas. Initially, the individual risk contours were calculated without considering mitigating measures, obtaining as result the individual risk contour with frequencies of 1x10{sup -06} per year involving sensitive occupations and therefore considered unacceptable when compared with the INEA criterion. The societal risk was calculated for eight densely populated areas and their respective FN-curves situated below the advised limit established by INEA, except for two areas that required the proposal of additional mitigating measures to the reduction of societal risk. Regarding to societal risk, the FN-curve should be below the advised limit presented in the Technical Instruction of INEA. The individual and societal risk were reassessed incorporating some mitigating measures and the results situated below the advised limits established by INEA and PETROBRAS has obtained the license for installation of the pipeline.

    2004-01-01

    Canada's National Energy Board (NEB) is responsible for the promotion of safety, environmental protection and economic efficiency in the Canadian public interest in regulating the design, construction, operation and abandonment of interprovincial and international pipelines within Canada. This second annual report provides a review of the safety performance of oil and gas pipeline companies that are regulated by the NEB. The data used to prepare this report originates from two sources: incident reports submitted under the Onshore Pipeline Regulations, 1999, and from information voluntarily provided by pipeline companies under the Safety Performance Indicators (SPI) initiative. Data comparisons with external reference organizations were included. Six key indicators have been identified to provide comprehensive measures of safety performance for pipeline companies: fatalities, ruptures, injury frequencies, liquid releases, gas releases, and unauthorized activities on the right of way. The safety performance of the federally regulated pipeline industry within Canada was satisfactory during this reporting period (2000-2002). The contractor injury frequency rates reported in 2002 were lower than those reported in 2001, and exhibited more consistency with the levels reported in 2000. The NEB is of the opinion that the elevated number of liquid hydrocarbon spills reported in 2000 were a result of elevated construction levels. No fatalities were reported. There was an increase to three from two in the number of ruptures, due in large part to metal loss (corrosion) and cracking, and external interference (third party damage). The number of spills increased to 76 in 2002 from 55 in 2001, which appears to be more in line with industry averages. The volume of hydrocarbon liquid released in 2002 represented one third the volume released in 2001. refs., 5 tabs., 14 figs

After the first run of the cleaning tool, was scheduled the launch of the dummy scraper (scraper tool) along to the first 210 Km of the 32 inches natural gas pipeline , given changes in elevation along the trace and the low flow of transport. This scraper tool could not reach the final destination. After many series operational maneuvers as venting, creation of differential pressure in valves, the scraper tool only reach the first 75 Km of the trace. After an exhaustive analysis of trending pressure variations, it was concluded that this scraper showed intermittent progress of short durations, concluding that this scraper had not reach the next check point. In this way was decided to conduct operational maneuvers in order to locate, relocated and retrieve the scrapper tool from de 32 inches natural gas pipeline. (author)

    PETROBRAS has been conducting several wildlife programs in response to environmental licensing requirements from IBAMA (Brazilian environmental agency). Since 2007, IBAMA has been requiring the application of the Normative Instruction n. 146 (NI), which establishes criteria for wildlife management in the influence areas of new enterprises. However, experience from PETROBRAS has shown that many of the NI articles are not applicable to pipelines. Thus, a critical analysis of this NI was done based on data from company's wildlife programs. Our analysis indicated that the main NI items that do not apply to pipelines are: 1 - Animal rescue programs in deforested areas and selection of release areas, 2 - More than two fauna monitoring campaigns a year, 3 - Monitoring programs involving all groups of terrestrial vertebrates and also invertebrate classes. The non-applicability of these items is due to: 1 - The majority of pipelines are built in areas without significant native vegetation or with small fragments only, which are usually in secondary stage of ecological succession. Most pipelines scarcely involve removal of primary vegetation, 2 - Pipelines have an influence area restricted to a range of 800 m and the construction directly affects only strips from 20 m to 30 m, 3 - The most relevant impacts associated with pipelines are temporary, and do not persist during their operation.

  14. Coalbed methane : evaluating pipeline and infrastructure requirements to get gas to market

    International Nuclear Information System (INIS)

    Murray, B.

    2005-01-01

    This Power Point presentation evaluated pipeline and infrastructure requirements for the economic production of coalbed methane (CBM) gas. Reports have suggested that capital costs for CBM production can be minimized by leveraging existing oil and gas infrastructure. By using existing plant facilities, CBM producers can then tie in to existing gathering systems and negotiate third party fees, which are less costly than building new pipelines. Many CBM wells can be spaced at an equal distance to third party gathering systems and regulated transmission meter stations and pipelines. Facility cost sharing, and contracts with pipeline companies for compression can also lower initial infrastructure costs. However, transmission pressures and direct connect options for local distribution should always be considered during negotiations. The use of carbon dioxide (CO 2 ) commingling services was also recommended. A map of the North American gas network was provided, as well as details of Alberta gas transmission and coal pipeline overlays. Maps of various coal zones in Alberta were provided, as well as a map of North American pipelines. refs., tabs., figs

    2010-01-01

    The trend for increased oil and gas consumption implies a growth of long-distance pipeline installations. Welding is a critical factor in the installation of pipelines, both onshore and offshore, and the rate at which the pipeline can be laid is generally determined by the speed of welding. This has resulted in substantial developments in pipeline welding techniques. Arc welding is still the dominant process used in practice, and forge welding processes have had limited successful application to date, in spite of large investments in process development. Power beam processes have also been investigated in detail and the latest laser systems now show promise for practical application. In recent years the use of high strength steels has substantially reduced the cost of pipeline installation, with X70 and X80 being commonly used. This use of high strength pipeline produced by thermomechanical processing has also been researched. They must all meet three requirments, high productivity, satisfactory weld properties, and weld quality

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

    Heating coils, for example, are wound around sea water pipelines as a heater. The outer wall surface of the sea water pipelines is heated by the heating coils. The inner wall surfaces of the sea water pipelines can be warmed to higher than a predetermined temperature by heating the outer wall surfaces to die out marine organisms deposited at the inner surfaces. Further, thermocouples for the external wall and the internal wall are disposed so that the temperature at the inner wall surface of the sea water pipelines can be controlled. Further, a temperature keeping material is disposed at the external surface of the sea water system pipelines. With such a constitution, the marine organisms deposited on the internal wall surface of the sea water system pipelines are died out to suppress the deposition amount of the marine organisms. Accordingly, the maintenance and the operation reliability is improved after maintenance. (I.N.)

    There is a battle on in Northern Chile to supply the region with gas and electricity. Two pipelines and a transmission line are being built, but there is insufficient demand to merit the construction of all of these projects. It is widely believed that the first pipeline to be finished will be the overall winner, but the situation is not that simple. A more sensible conclusion could be the merger of the two pipeline projects, rationalising supply of gas to the region. (Author)

  7. Thermal expansion absorbing structure for pipeline

    International Nuclear Information System (INIS)

    Nagata, Takashi; Yamashita, Takuya.

    1995-01-01

    A thermal expansion absorbing structure for a pipeline is disposed to the end of pipelines to form a U-shaped cross section connecting a semi-circular torus shell and a short double-walled cylindrical tube. The U-shaped longitudinal cross-section is deformed in accordance with the shrinking deformation of the pipeline and absorbs thermal expansion. Namely, since the central lines of the outer and inner tubes of the double-walled cylindrical tube deform so as to incline, when the pipeline is deformed by thermal expansion, thermal expansion can be absorbed by a simple configuration thereby enabling to contribute to ensure the safety. Then, the entire length of the pipeline can greatly be shortened by applying it to the pipeline disposed in a high temperature state compared with a method of laying around a pipeline using only elbows, which has been conducted so far. Especially, when it is applied to a pipeline for an FBR-type reactor, the cost for the construction of a facility of a primary systems can greater be reduced. In addition, it can be applied to a pipeline for usual chemical plants and any other structures requiring absorption of deformation. (N.H.)

    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.

    The ownership structure of Finland's leading natural gas company, Gasum, changed fundamentally in 1999, and the company is now no longer a subsidiary of Fortum Corporation. 'Our new strong and broad ownership base will enable us to develop the natural gas business and pipeline network in Finland in response to the requirements of our Finnish customers', says Antero Jaennes, Gasum's Chairman and CEO, who stresses that Gasum is committed to remaining the leading developer of the Finnish natural gas market and the number-one gas supplier. Natural gas usage in Finland in 1999 totalled 3.9 billion m 3 (38.7 TWh), unchanged from 1998. Natural gas accounted for 11% of Finland's total primary energy need, as it did in 1998. The proportion of natural gas used in district heating rose by 2% to 36%, and moved down 2% in power generation to 10%. Industry's use of natural gas fell 1% to 17%. 75% of natural gas was used in combined heat and power (CHP) generation in industry and district heating. In 2000, Gasum expects to sell 4 billion m 3 of natural gas (40 TWh)

    Analysis pipelines are an essential part of bioinformatics research, and ad hoc pipelines are frequently created by researchers for prototyping and proof-of-concept purposes. However, most existing pipeline management system or workflow engines are too complex for rapid prototyping or learning the pipeline concept. A lightweight, user-friendly and flexible solution is thus desirable. In this study, we developed a new pipeline construction and maintenance tool, PipelineDog. This is a web-based integrated development environment with a modern web graphical user interface. It offers cross-platform compatibility, project management capabilities, code formatting and error checking functions and an online repository. It uses an easy-to-read/write script system that encourages code reuse. With the online repository, it also encourages sharing of pipelines, which enhances analysis reproducibility and accountability. For most users, PipelineDog requires no software installation. Overall, this web application provides a way to rapidly create and easily manage pipelines. PipelineDog web app is freely available at http://web.pipeline.dog. The command line version is available at http://www.npmjs.com/package/pipelinedog and online repository at http://repo.pipeline.dog. ysun@kean.edu or xing@biology.rutgers.edu or ysun@diagnoa.com.

    1997-01-01

    Operations and financial activities of TransCanada PipeLines Limited (TPL) during 1996 were reviewed and made available for the benefit of shareholders. TransCanada PipeLines Limited is a Canadian company with assets in excess of $12 billion. Its pipeline system transports natural gas and crude oil from the Western Canada Sedimentary Basin to North America's major energy markets. By all accounts the company had a successful year in 1996, having delivered a record 2.4 Bcf of gas, up 3.7 per cent from 1995, through the Canadian Mainline, TransCanada's largest asset. Among other notable achievements was the decision to join the Portland Natural Gas Transmission System as a 20 per cent partner in a project to construct a natural gas pipeline between Quebec and Haverhill, Massachusetts. Another accomplishment was the completion of the acquisition of all remaining shares of Alberta Natural Gas company, thereby extending the company's energy transmission, gas processing and specialty chemical operations. Other achievements were the purchase of Enron Louisiana Energy Company, the acquisition of assets that position TPL as one of the largest natural gas liquids processors in North America and the completion and commissioning of two new independent power generation plants in Ontario. Shareholder's return on investment was 34 per cent, more than double the target of between 12 to 15 per cent. Net income to common shares amounted to $1.85 per share, up from $1.75 in 1995. The strong performance was attributed to continued growth in all four segments of TPL's business, i. e. energy transmission, energy marketing, energy processing and international. tabs., figs

    A secure and affordable energy supply is essential for achieving U.S. national security, in continuing U.S. prosperity and in laying the foundations to enable future economic growth. To meet this goal the next generation energy workforce in the U.S., in particular those needed to support instrumentation, controls and advanced operations and maintenance, is a critical element. The workforce is aging and a new workforce pipeline, to support both current generation and new build has yet to be established. The paper reviews the challenges and some actions being taken to address this need.

The difference was primarily due to a general increase in retail rates which became effective in January 1989 for distribution customers in the state. A December 1989 settlement of a pipeline subsidiary's rate increase also added to the increase. The rate increase had been in effect since 1986, but the full effect had been reserved pending the outcome of regulatory proceedings, the company stated

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

    International Nuclear Information System (INIS)

    Brown, R.J.

    1990-01-01

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

    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.

    An overview of the Canadian pipeline industry's initiatives to limit greenhouse gas (GHG) emissions was presented. The commitment of the Canadian Energy Pipeline Association (CEPA) and its 11 member companies to the Voluntary Climate Change Challenge Program which aims to stabilize GHG emissions at 1990 levels by the year 2000, was reaffirmed. At the same time, questions were raised about whether the absolute reduction of greenhouse gas emissions to 1990 levels is a realistic or desirable goal for the Canadian transmission pipeline industry, given the increased demand for Canadian gas and petroleum products both domestically and internationally. it was argued that the Voluntary Climate Change Challenge Program must recognize the differing abilities of Canada's economic sectors to achieve absolute reductions in greenhouse gas emissions

    The growing concern of PETROBRAS with the environmental protection aspects is intimately related with the need of developing preventive works of protection to the pipelines of the company. A study was accomplished in the pipelines inside the Guanabara Bay, whose goals was divided in three parts: identification of the risk areas for the pipelines; determination of the minimum depth of burying of the pipelines so that the risk in appreciation is minimized; identification of the areas in that the burying or a complemental burying make herself necessary. The study went based on to theory of conservation of energy, being admitted the non preservative embarkation system, and in the theory of the elasticity. For such a commercial program of finite elements was used. With base in the limits foreseen in the study, two critical areas of the Guanabara Bay were considered, which already suffered intervention with lowering. (author)

  6. Internal corrosion control of northern pipelines

    Energy Technology Data Exchange (ETDEWEB)

    Papavinasam, S.

    2005-02-01

    The general causes of internal corrosion in pipelines were discussed along with the methods to control them. Efficient methods are needed to determine chemical efficiency for mitigating internal corrosion in transmission pipelines, particularly those used in environmentally sensitive regions in the Arctic where harsh environmental conditions prevail. According to the Office of Pipeline Safety, 15 per cent of pipeline failures in the United States from 1994 to 2000 were caused by internal corrosion. Since pipelines in the United States are slightly older than Canadian pipelines, internal corrosion is a significant issue from a Canadian perspective. There are 306,618 km of energy-related pipelines in western Canada. Between April 2001 and March 2002 there were 808 failures, of which 425 failures resulted from internal corrosion. The approach to control internal corrosion comprises of dehydrating the gases at production facilities; controlling the quality of corrosive gases such as carbon dioxide and hydrogen sulphide; and, using internal coatings. The approaches to control internal corrosion are appropriate, when supplemented by adequate integrity management program to ensure that corrosive liquids do not collect, over the operational lifetime of the pipelines, at localized areas. It was suggested that modeling of pipeline operations may need improvement. This paper described the causes, prediction and control of internal pitting corrosion. It was concluded that carbon steel equipment can continue to be used reliably and safely as pipeline materials for northern pipelines if the causes that lead to internal corrosion are scientifically and accurately predicted, and if corrosion inhibitors are properly evaluated and applied. 5 figs.

    A Software for 'pipeline integrity management' was developed. It allows to deal with Geographical Information and a PODS database (Pipeline Open database Standard) simultaneously, in a simple and reliable way. The premises for the design were the following: didactic, geo referenced, multiple reference systems. Program skills: 1.PODS+GIS: the PODS database in which the software is based on is completely integrated with the GIS module. 2 Management of different kinds of information: it allows to manage information on facilities, repairs, interventions, physical inspections, geographical characteristics, compliance with regulations, training, offline events, operation measures, O and M information treatment and importing specific data and studies in a massive way. It also assures the integrity of the loaded information. 3 Right of way survey: it allows to verify the class location, ROW occupation, sensitive areas identification and to manage landowners. 4 Risk analysis: it is done in a qualitative way, depending on the entered data, allowing the user to identify the riskiest stretches of the system. Either results from risk analysis, data and consultations made about the database, can be exported to standard formats. (author)

  16. Electrical fingerprint of pipeline defects

    International Nuclear Information System (INIS)

    Mica, Isabella; Polignano, Maria Luisa; Marco, Cinzia De

    2004-01-01

    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

  17. System reliability of corroding pipelines

    International Nuclear Information System (INIS)

    Zhou Wenxing

    2010-01-01

    A methodology is presented in this paper to evaluate the time-dependent system reliability of a pipeline segment that contains multiple active corrosion defects and is subjected to stochastic internal pressure loading. The pipeline segment is modeled as a series system with three distinctive failure modes due to corrosion, namely small leak, large leak and rupture. The internal pressure is characterized as a simple discrete stochastic process that consists of a sequence of independent and identically distributed random variables each acting over a period of one year. The magnitude of a given sequence follows the annual maximum pressure distribution. The methodology is illustrated through a hypothetical example. Furthermore, the impact of the spatial variability of the pressure loading and pipe resistances associated with different defects on the system reliability is investigated. The analysis results suggest that the spatial variability of pipe properties has a negligible impact on the system reliability. On the other hand, the spatial variability of the internal pressure, initial defect sizes and defect growth rates can have a significant impact on the system reliability.

    Full text : For increase of ecological safety of the pipeline, necessary decrease of damage (risk) rendered by the pipeline on surrounding natural environment which depends: on the frequency of damage of the pipeline; on the volume poured oil; on the factor of sensitivity of an environment where flood of oil was. Frequency of damage of the pipeline depends on physico-chemical properties of a material of the pipeline, from its technical characteristics (thickness of a wall, length of a pipe, working pressure), on the seismic area of the district where the pipeline passed and also on the way of lining of the pipeline (underground or overground). The volume poured oil depends on diameter of the received damage, from stability of the pipeline mechanical and other external actions, from an ambient temperature, from capacity of the pipeline, from distance between the latches established in the pipeline, and also from time, necessary for their full closing. The factor of sensitivity of environment depends on geological structure and landscapes of district (mountain, the river, settlements) where passed the pipeline. At designing the pipeline, in report is shown questions of increase of ecological safety of the pipeline are considered at his construction and exploitation. For improvement of ecological safety of the pipeline is necessary to hold the following actions: Ecological education of the public, living near along a line of the oil pipeline; carrying out ecological monitoring; working of the public plan of response to oil spills; For ecological education of the public is necessary: carrying out informing of the public for all (technical, ecological, social and economic and legal) questions connected to an oil pipeline, and also on methods of protection of the rights at participation in acceptance of ecological significant decisions; Creation of public groups for realization of activity on observance of the legislation and to prevention of risks; Exposure of hot

    Pipeline leak detection method based on dynamic pressure is studied. The feature of dynamic pressure which is generated by the leakage of pipeline is analyzed. The dynamic pressure method is compared with the static pressure method for the advantages and disadvantages in pipeline leak detection. The dynamic pressure signal is suitable for pipeline leak detection for quick-change of pipeline internal pressure. Field tests show that the dynamic pressure method detects pipeline leak rapidly and precisely. (author)

    Pipeline regulations implemented in 2006 require that licensees register all pipelines. Training must also be provided for ground disturbance supervisors. In addition, signage must be maintained on abandoned pipelines, and discontinued pipelines must be properly isolated. Corrosion control and internal inhibition is required for discontinued lines. However, pipelines are often neglected during the well abandonment process. This presentation provided recommendations for coordinating well and pipeline abandonment processes. Pipeline ends can be located, depressurized, flushed and purged while wells are being abandoned. Contaminated soils around the wells can also be identified prior to reclamation activities. Administrative reviews must be conducted in order to provide accurate information on pipeline location, reclamation certification, and line break history. Field operation files must be reviewed before preliminary field work is conducted. Site inspections should be used to determine if all ends of the line are accessible. Landowners and occupants near the line must also be notified, and relevant documentation must be obtained. Skilled technicians must be used to assess the lines for obstructions as well as to cut and cap the lines after removing risers. The presentation also examined issues related to pressure change, movement, cold tapping, and live dead legs. tabs., figs.

    2008-07-01

    Production characteristics and gas-fluid compositions of fluids must be known in order to assess pipelines for internal corrosion risk. In this study, a gathering system pipeline network was built in order to determine corrosion risk for gathering system pipelines. Connections were established between feeder and collector lines in order measure upstream production and the weighted average of the upstream composition of each pipeline in the system. A Norsok M-506 carbon dioxide (CO{sub 2}) corrosion rate model was used to calculate corrosion rates. A spreadsheet was then used to tabulate the obtained data. The analysis used straight lines drawn between the 'from' and 'to' legal sub-division (LSD) endpoints in order to represent pipelines on an Alberta township system (ATS) and identify connections between pipelines. Well connections were established based on matching surface hole location and 'from' LSDs. Well production, composition, pressure, and temperature data were sourced and recorded as well attributes. XSL hierarchical computations were used to determine the production and composition properties of the commingled inflows. It was concluded that the corrosion assessment process can identify locations within the pipeline network where potential deadlegs branched off from flowing pipelines. 4 refs., 2 tabs., 2 figs.

    Pipelines after decontamination of radioactive nuclides deposited on the pipelines in a nuclear power plant during operation or pipelines to replace pipelines deposited with radioactive nuclide are connected to each system of the nuclear power plant. They are heated in a gas phase containing oxygen to form an oxide film on the surface of the pipelines. The thickness of the oxide film formed in the gas phase is 1nm or greater, preferably 100nm. The concentration of oxygen in the gas phase containing oxygen must be 0.1% or greater. The heating is conducted by circulating a heated gas to the inside of the pipelines or disposing a movable heater such as a high frequency induction heater inside of the pipelines to form the oxide film. Then, redeposition of radioactive nuclide can be suppressed and since the oxide film is formed in the gas phase, a large scaled facilities are not necessary, thereby enabling to repair pipelines of reactor primary system at low cost.

It is well known that leaks in the piping associated with these systems account for a sizeable fraction of the leaks. EPA has established performance standards for pipeline leak detection systems, and published a document presenting test protocols for evaluating these systems against the standards. This paper discusses a number of facets and important features of evaluating such systems, and presents results from tests of several systems. The importance of temperature differences between the ground and the product in the line is shown both in theory and with test data. The impact of the amount of soil moisture present is addressed, along with the effect of frozen soil. These features are addressed both for line tightness test systems, which must detect leaks of 0.10 gal/h (0.38 L/h) at 150% of normal line pressure, or 0.20 gal/h (0.76 L/h) at normal line pressure, and for automatic line leak detectors that must detect leaks of 3 gal/h (11 L/h) at 10 psi (69 kPa) within an hour of the occurrence of the leak. This paper also addresses some statistical aspects of the evaluation of these systems. Reasons for keeping the evaluation process ''blind'' to the evaluated company are given, along with methods for assuring that the tests are blind. Most importantly, a test procedure is presented for evaluating systems that report a flow rate (not just a pass/fail decision) that is much more efficient than the procedure presented in the EPA protocol, and is just as stringent

    The revival of interest in Arctic natural gas and the developing competition to extend the pipeline grid to Alaska and the Yukon and the Northwest territories are the subject of this report. Substantial agreement between competing interest groups is reported with respect to the need for Arctic gas and the willingness of the market to pay for bringing it south to consumers. The discussion centers on the construction of the Alliance Pipeline Project that will reportedly bring two billion cubic feet per day of excess capacity to transport natural gas from northeastern British Columbia to Chicago, and the 2,400 km long Foothills Pipelines System that carries about one-third of Canadian gas exports to middle-western states and California. Plans are to extend the line to 5,240 km by laying pipe in a giant Y pattern between Prudhoe Bay and the Mackenzie delta in the north, and the start of the Foothills System at Caroline in central Alberta. The estimated cost of the line is about $US 6 billion, using a 36-inch diameter line at increased pressures in place of the 56-inch diameter pipe used in the 1970s. Construction plans are similar for the rest of the big Y, the Dempster Lateral beside the Dempster Highway between Whitehorse and Inuvik. A competing project, the Northern Gas Pipeline Project is also discussed. This line would run east of Prudhoe Bay under the Beaufort Sea to the Mackenzie Delta; then south along the Mackenzie Valley to Alberta. Cost of this line is also estimated at $US 6 billion, however, it would have a capacity of four billion cubic feet per day, including 2.5 billion cubic feet from Alaska and 1.5 billion cubic feet from Canada. Strong revival of interest is also reported from the supply side, with BP Amoco, ARCO, Chevron Canada Resources, Ranger 0il Ltd., Paramount Resources, Berkley Petroleum Corporation, Canadian Forest Oil, Alberta Energy Company, Petro-Canada, Anderson Resources, and Poco Petroleum Ltd., all showing interest to mount new

    This paper describes a technical procedure to assess a software based leak detection system (LDS), by deciding between a simpler low cost, less effective product, having a fast installation and tuning, and a complex one with high cost and efficiency, which however takes a long time to be properly installed. This is a common decision among the pipeline operating companies, considering that the majority of the lines are short, with single phase liquid flow (which may include batches), basic communication system and instrumentation. Service companies offer realistic solutions for liquid flow, but usually designed to big pipeline networks, flowing multiple batches and allowing multiple fluid entrances and deliveries. Those solutions are sometimes impractical to short pipelines, due to its high cost, as well as long tuning procedures, complex instrumentation, communication and computer requirements. It is intended to approach here the best solution according to its cost. In a practical sense, it means to differentiate the various LDS techniques. Those techniques are available in a considerable number, and they are still spreading, according to the different scenarios. However, two most known and worldwide implemented techniques hold the majority of the market: the Compensated Volume Balance (CVB), which is less accurate, reliable and robust, but cheaper, simpler and faster to install, and the Real Time Transient Model (RTTM), which is very reliable, accurate and robust, but expensive and complex. This work will describe a way to define whether one can use or not a CVB in a pipeline. (author)

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

    Routes of the proposed Millennium Pipeline project were presented. The pipeline is to originate at the Empress gas field in Alberta and link up to eastern markets in the United States. One of the key advantages of the pipeline is that it will have the lowest proposed rates from Empress to Chicago and through links via affiliates to New York and other eastern markets. It will include 380 miles of new 36-inch pipeline and have a capacity of 650 million cubic feet per day. In many instances it will follow existing rights-of-way. The pipeline is expected to be in service for the 1999 winter heating season. The project sponsors are Columbia Gas Transmission, CMS Energy, MCN Energy, and Westcoast Energy. 6 figs

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

    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.

  19. Location of leaks in pressurized underground pipelines

    Eckert, E.G.; Maresca, J.W. Jr.

    1993-01-01

    Millions of underground storage tanks (UST) are used to store petroleum and other chemicals. The pressurized underground pipelines associated with USTs containing petroleum motor fuels are typically 2 in. in diameter and 50 to 200 ft in length. These pipelines typically operate at pressures of 20 to 30 psi. Longer lines, with diameters up to 4 in., are found in some high-volume facilities. There are many systems that can be used to detect leaks in pressurized underground pipelines. When a leak is detected, the first step in the remediation process is to find its location. Passive-acoustic measurements, combined with advanced signal-processing techniques, provide a nondestructive method of leak location that is accurate and relatively simple, and that can be applied to a wide variety of pipelines and pipeline products

  2. Crossing Active Faults on the Sakhalin II Onshore Pipeline Route: Analysis Methodology and Basic Design

    International Nuclear Information System (INIS)

    Vitali, Luigino; Mattiozzi, Pierpaolo

    2008-01-01

    Twin oil (20 and 24 inch) and gas (20 and 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

  3. The impact of changing pipeline BS and W specifications : a survey

    1997-01-01

    The current situation in Canada and in the US regarding BS and W was presented. In Canada BS and W specifications are 0.5 per cent and are the same for light and heavy oils, while in the US, BS and W specifications range from 0.5 to 3 per cent. Some pipelines allow more relaxed specifications for heavy oil. A telephone survey was conducted in which 12 producers, 25 pipeline representatives and 18 upgrader facilities from 45 different sites in Canada and the US were contacted. Contacts were questioned on which components in crude oil most affected their operations and their reaction to changing pipeline BS and W specifications. The most troublesome component, according to the majority of contacts, were solids. Downstream users cannot accept any increase in solids within the crude. Many pipeline companies would like to see solids regulated separately from water. There are several advantages and disadvantages for producers, pipeliners, and refiners in relaxing water limits. Among the advantages, flash evaporation proved to provide the strongest case for relaxing water limits. 1 fig

  4. Effective use of the income trust as a vehicle to monetize pipeline assets

    International Nuclear Information System (INIS)

    Stedman, W. R.

    1998-01-01

    The application of the income trust structure as a method of financing pipeline and other long-life assets was explored. The case of Pembina Pipeline Corporation was used to illustrate the use of this method of financing. In this case, the assets of Pembina Pipeline were sold to the Pembina Pipeline Income Trust, with significant advantages afforded to the vendor, the issuer, and ultimately the individual investor. The success of income funds is based on the investor's willingness to use a yield type valuation methodology, as opposed to traditional price/earnings or price/cash flow methodologies. Such funds are characterized by stability of the underlying business, including the ability to handle high payout ratios, and minimization of the overall tax burden, since corporate taxes are lessened as part of the capitalization structure. The objective of income trust funds is to distribute operating cash flow directly to investors while minimizing income taxes at the corporate income level through the creation of the subordinated debt and common equity. The value is created by the tax efficiency inherent in the system, as interest expense on the notes is used to shield taxable income in the operating company. The process of creating the Pembina Pipelines Income Trust Fund was described to demonstrate the application of the structure

  5. Impact of the rheological studies in the transport for pipeline of paraffinic crude oils

    2000-01-01

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

  6. Mackenzie Valley Pipeline market demand, supply, and infrastructure analysis : final report

    International Nuclear Information System (INIS)

    2004-01-01

    Mackenzie Valley Pipeline Co-Venturers is a consortium of petroleum companies proposing to construct a 1,400 km long, large-diameter, high-pressure natural gas transmission pipeline from the northwestern edge of the Northwest Territories to the Alberta-Northwest Territories border. The Mackenzie Valley Pipeline will bring natural gas from the Mackenzie Delta region to markets in Alberta, central and eastern Canada and the United States. Navigant Consulting Ltd. prepared this assessment of the long-term market need for natural gas produced from the Mackenzie Delta. It presents an analysis of gas demand, supply and infrastructure. Three sensitivity cases were examined, incorporating different assumptions about the initial capacity of the pipeline, potential expansion of its capacity and different levels of gas demand in Canada and the United States. The report indicates that gas markets in North America support construction of the proposed 34 million cubic metre per day pipeline in the 2009 timeframe, with possible expansion in 2015 and 2020. It also indicates that there will be enough capacity on the intra-Alberta gas transmission system to accommodate the projected deliveries of Mackenzie Delta gas. The increase in gas demand is due to an increase in residential and commercial gas consumption, electric power generation and the energy intensive bitumen extraction and processing activities in the Alberta oil sands industry. 36 tabs., 56 figs

    In order to mitigate the effects caused by the rupture of a gas pipeline and following ASME B 31.8 recommendations, block valves are installed in these structures. However, many transportation companies also install devices capable of infer the occurrence of an accident in a gas pipeline. The most common devices are the ones that actuate when pressure in gas pipeline reaches a low value early established (PSL) and those which close valves due to high rate of pressure drop (line-break). Line-break has the function of identifying as fast as possible the occurrence of a rupture in a gas pipeline by high rate of pressure drop in that line. Although PSL presents a later actuation when compared to the line break, it represents redundancy to the line-break system, since it is able to isolate the segment where the accident happened even if other devices or the operator had not done it before. The growing of gas pipelines transport capacity has been generated transients capable of causing an erroneous shut down of the shut down valves (SDV). The aim of this paper, therefore, is to present how the operational limits of SDV can be overcome with remote operation using SCADA System. (author)

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

    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)

    We present the VLA Pipeline, software that is part of the larger pipeline processing framework used for the Karl G. Jansky Very Large Array (VLA), and Atacama Large Millimeter/sub-millimeter Array (ALMA) for both interferometric and single dish observations.Through a collection of base code jointly used by the VLA and ALMA, the pipeline builds a hierarchy of classes to execute individual atomic pipeline tasks within the Common Astronomy Software Applications (CASA) package. Each pipeline task contains heuristics designed by the team to actively decide the best processing path and execution parameters for calibration and imaging. The pipeline code is developed and written in Python and uses a "context" structure for tracking the heuristic decisions and processing results. The pipeline "weblog" acts as the user interface in verifying the quality assurance of each calibration and imaging stage. The majority of VLA scheduling blocks above 1 GHz are now processed with the standard continuum recipe of the pipeline and offer a calibrated measurement set as a basic data product to observatory users. In addition, the pipeline is used for processing data from the VLA Sky Survey (VLASS), a seven year community-driven endeavor started in September 2017 to survey the entire sky down to a declination of -40 degrees at S-band (2-4 GHz). This 5500 hour next-generation large radio survey will explore the time and spectral domains, relying on pipeline processing to generate calibrated measurement sets, polarimetry, and imaging data products that are available to the astronomical community with no proprietary period. Here we present an overview of the pipeline design philosophy, heuristics, and calibration and imaging results produced by the pipeline. Future development will include the testing of spectral line recipes, low signal-to-noise heuristics, and serving as a testing platform for science ready data products.The pipeline is developed as part of the CASA software package by an

    This Paper details the implementation of a 'Decommissioning Trial' to assess the feasibility of decommissioning the redundant pipeline operated by AWE located in Berkshire UK. The paper also presents the tool box of decommissioning techniques that were developed during the decommissioning trial. Constructed in the 1950's and operated until 2005, AWE used a pipeline for the authorised discharge of treated effluent. Now redundant, the pipeline is under a care and surveillance regime awaiting decommissioning. The pipeline is some 18.5 km in length and extends from AWE site to the River Thames. Along its route the pipeline passes along and under several major roads, railway lines and rivers as well as travelling through woodland, agricultural land and residential areas. Currently under care and surveillance AWE is considering a number of options for decommissioning the pipeline. One option is to remove the pipeline. In order to assist option evaluation and assess the feasibility of removing the pipeline a decommissioning trial was undertaken and sections of the pipeline were removed within the AWE site. The objectives of the decommissioning trial were to: - Demonstrate to stakeholders that the pipeline can be removed safely, securely and cleanly - Develop a 'tool box' of methods that could be deployed to remove the pipeline - Replicate the conditions and environments encountered along the route of the pipeline The onsite trial was also designed to replicate the physical prevailing conditions and constraints encountered along the remainder of its route i.e. working along a narrow corridor, working in close proximity to roads, working in proximity to above ground and underground services (e.g. Gas, Water, Electricity). By undertaking the decommissioning trial AWE have successfully demonstrated the pipeline can be decommissioned in a safe, secure and clean manor and have developed a tool box of decommissioning techniques. The tool box of includes

    During the second quarter of 2011 VIR-MS (VIS and IR Mapping Spectrometer) [1] aboard Dawn mission [2] has approached Vesta in order to start a long period of acquisitions that will end at the beginning of 2012. Data acquired by each instrument always require a calibration process in order to remove all the instrument effects that could affect the scientific evaluations and analysis. VIR-MS instrument team has realized a calibration pipeline which has the goal of producing calibrated (1b level) data starting from the raw (1a level) ones. The other goal of the tool has been the check of the goodness of acquired data by means of the evaluation of a series of minimum requisites of each data file, such as the percentage of the saturated pixels, the presence of spikes or the mean S/N ratio of each qube.

    The potential for growth in the U.S. northeast natural gas markets was discussed. In presenting a forecast for natural gas consumption, the growth in demand was attributed primarily to the planned conversion of coal and oil-fired electric generation plants to gas-fired ones, combined with nuclear plant shutdowns, and more stringent environmental policies. An overview of the development of the Millennium Pipeline bringing natural gas from the Alberta border all the way to New York City was also provided, with an update on the current status of the project. Assuming no unreasonable delays in the present schedule, the line should be in service sometime in the year 2000. figs

It updates to 2012 data provided by recent publications, and integrates these analyses with information on location of trials coordinators and patients recruitment status. Additionally, it provides (i) disease-specific information to better understand the rational of investments in NDs, (ii) yearly data, to understand the investment trends. The search identified 650 clinical studies. Leishmaniasis, Arbovirus infection, and Dengue are the top three diseases by number of clinical studies. Disease diffusion risk seems to be the most important driver of the clinical trials target choice, whereas the role played by disease prevalence and unmet need is controversial. Number of trials is stable between 2005 and 2010, with an increase in the last two years. Patient recruitment was completed for most studies (57.6%), and Phases II and III account for 35% and 28% of trials, respectively. The primary purpose of clinical investigations is prevention (49.3%), especially for infectious diseases with mosquitoes and sand flies as the vector, and treatment (43.2%), which is the primary target for parasitic diseases Research centres and public organisations are the most important clinical studies sponsors (58.9%), followed by the pharmaceutical industry (24.1%), foundations and non-governmental organisations (9.3%). Many coordinator centres are located in less affluent countries (43.7%), whereas OECD countries and BRICS account for 34.7% and 17.5% of trials, respectively. Information was partially missing for some parameters. Notwithstanding, and despite its descriptive nature, this research has enhanced the evidence of the literature on pipelines for NDs. Future contributions may further investigate whether trials metrics are consistent with the characteristics of the interested countries and the explicative variables of trials location, target

    When the construction of a pipeline has been completed, the pipeline flooding is done as part of the pipeline commissioning process. This method consists of filling the empty pipe with water or oil. In a pipeline situated in hilly terrain, air entrapped in the fluid causes problems with the flooding process and it is necessary to discharge the accumulated air to address this issue. The aim of this paper is to provide a model for predicting the location and volume of air pockets in a pipeline. This model was developed based on the fundamentals of mass balance and momentum transfer in multiphase flow and was then applied to a pipeline in China and compared with the SCADA data. Results showed a good match between the model's predictions of hydraulic movement and the real data from SCADA. The two flow model developed can predict hydraulic movement during pipeline flooding in a hilly area and thus it can be used to predict water front location and air pocket movement in the pipe.

  17. Laser-based gas sensors keep moisture out of pipelines

    Natural gas often contains contaminants that cause corrosion, and long-term deterioration, and must be cleaned and brought to pipeline standards before it can be delivered to high-pressure, long-distance pipelines. Many older sensors produce false data that can result in contaminated gas getting through. This article presented details of the SpectraSensor, a new laser-based sensor technology used by the El Paso Natural Gas Company (EPNG). The SpectraSensor is comprised of a tunable diode laser (TDL) based technology developed by the National American Space Agency (NASA). The gas analyzer provides non-contact measurement of moisture, carbon dioxide, and other corrosives in natural gas pipelines, and the tunable laser-based gas sensors are fast, accurate, and flexible. Producers can monitor El Paso's gas analyzer readings by capturing the electronic signal from El Paso's unit via a SCADA system and view the readings from control rooms. While initial purchase price is higher than more problematic surface-based gas sensors, an evaluation of the technology has indicated that maintenance savings alone may provide an almost immediate return on investments. Unlike electrochemical and crystal gas sensors, laser-based gas analyzers do not come into direct contact with any substances, a fact which practically eliminates maintenance and operational costs. Studies have shown that the cost of operating conventional electrochemical sensors can result in a cumulative annual expense exceeding $50,000 per unit including labour; recalibration and rebuilding; back-up sensor heads; and gas dehydration and tariffs. 1 fig.

  18. 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

    This paper discusses optimization strategies and techniques for the location of natural gas marketing hubs in the North American gas pipeline network. A hub is a facility at which inbound and outbound network links meet and freight is redirected towards their destinations. Common examples of hubs used in the gas pipeline industry include gas plants, interconnects and market centers. Characteristics of the gas pipeline industry which are relevant to the optimization of transportation costs using hubs are presented. Allocation techniques for solving location-allocation problems are discussed. An outline of the research in process by the authors in the field of optimal gas hub location concludes the paper.

    The Automated Radio Telescope Image Processing Pipeline (ARTIP) automates the entire process of flagging, calibrating, and imaging for radio-interferometric data. ARTIP starts with raw data, i.e. a measurement set and goes through multiple stages, such as flux calibration, bandpass calibration, phase calibration, and imaging to generate continuum and spectral line images. Each stage can also be run independently. The pipeline provides continuous feedback to the user through various messages, charts and logs. It is written using standard python libraries and the CASA package. The pipeline can deal with datasets with multiple spectral windows and also multiple target sources which may have arbitrary combinations of flux/bandpass/phase calibrators.

    The pandemic of multidrug-resistant (MDR) pathogens and their continuing spread is beyond dispute. In contrast to the past, today's antibacterial research and development (R&D) pipelines are nearly dry, failing to provide the flow of novel antibiotics required to match the clinical challenges of the multidrug resistance (MDR) crisis. Concerned over the rapidly worsening potential global healthcare crisis caused by MDR bacteria and the lack of robust drug pipelines, several multinational campaigns have issued policy recommendations and have initiated broad discussion with a goal of stimulating the development of novel antibacterial drugs and technologies. These activities have resulted in intensified co-operation between the USA and the EU. The recently announced extensive 'Action plan against the rising threats from antimicrobial resistance' substantially ramps up action within the EU. In recognising the potential crisis caused by MDR and the limited treatment options, the European Commission decided on an unprecedented approach to drive the search for novel antibiotics by integrating the pharmaceutical industry, the research capacities of universities and small companies supported by public funding along with pricing/reimbursement and regulatory bodies. The European Commission has shown leadership and put action plans in place. Only the future will tell whether these initiatives will help curb the impact of the MDR pandemic.

    Pemex Gas has 12,134 km of natural gas transmission pipelines, 1,835 Km for LPG and 1,216 Km for basic petrochemicals. The must part of this infrastructure was built in the 70's and reaching their 35 years of operating life. To manage the integrity of the three systems, Pemex Gas has a portfolio of technological tools. This tools allow the Company to improves the decision taking, align the budget with their strategic goals, achieve efficient asset utilization, and increase the value generation. The process of integrity management starts with the risk evaluation on assets, with the use of a software called IAP (Integrity Assessment Program). This information is integrated to the SIIA (Assets Identification System). The results of both software are used to the construction of the Risk Atlas, which identifies graphically each pipeline segment, with their related risk and factors that influence their behavior. The Risk Atlas gives us information about the consequences to the people, environment and facilities, so we can design customized plans to prevent or mitigate emergencies. Finally a detailed analysis of the resulting information and scenarios simulations help us to determine the best investment projects that will minimize the risk through all our assets. (author)

    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.

  7. A Novel Method to Enhance Pipeline Trajectory Determination Using Pipeline Junctions.

    2016-04-21

    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.

It is therefore necessary that the flow diagrams of a plant are clearly understandable and in accordance with the technical rules even in the early stages of planning. This book concentrates on steel pipeline which are not laid underground but of the type used mostly in industrial applications. The pictures and equations provided can be used for the design of pipelines, tables and diagrams are given to facilitate estimation of elasticity, pipeline pressure losses and insulating thicknesses. An overview of the equations is given at the end of the book. Many examples facilitate learning. (orig.) [de

    The future is bright for continued development of Australia's natural gas pipeline infrastructure, as well as for privatization and private energy infrastructure growth. Gas demands are growing and the development of open access principles for all natural gas transmission and distribution pipelines heralds a much more market focused industry. Within the next few years gas-on-gas competition will apply to supply, pipelines, and retail marketing. No longer will operators be able to pass on high costs resulting from inefficiencies to their customers. This article describes the changing Australian gas industry, evaluates the drivers for change and looks at ways the industry is responding to new regulatory regimes and the development and use of new pipeline technology

    During the construction of a pipeline, the IENE - Engineering Unit of PETROBRAS, responsible for the construction and erection of pipelines and related plants in northeastern Brazil, crossed more than 7 states and 250 counties, had implemented a social responsibility program, in special a citizenship program. This action was the result of community studies located near of the pipelines AID - Direct Influence Area (438 yards right and left of the pipeline) and through the evidence that those locations were poor and have no personal documents and citizen position in society. This paper intents to share the experience of IENE about its citizen program that worked in three big lines: community mobilization; citizenship qualification; and citizenship board. This last one, turns possible to people obtains theirs personal documents and exercise the plenitude of citizenship. (author)

    Due to heterogeneity of the subsurface in the delta environment of the Netherlands, differential subsidence over short distances results in tension and subsequent wear of subsurface infrastructure, such as water and gas pipelines. Due to uncertainties in the build-up of the subsurface, however, it is unknown where this problem is the most prominent. This is a problem for asset managers deciding when a pipeline needs replacement: damaged pipelines endanger security of supply and pose a significant threat to safety, yet premature replacement raises needless expenses. In both cases, costs - financial or other - are high. Therefore, an interdisciplinary research team of geotechnicians, geologists and Big Data engineers from research institutes TNO, Deltares and SkyGeo developed a stochastic model to predict differential subsidence and the probability of consequent pipeline failure on a (sub-)street level. In this project pipeline data from company databases is combined with a stochastic geological model and information on (historical) groundwater levels and overburden material. Probability of pipeline failure is modelled by a coupling with a subsidence model and two separate models on pipeline behaviour under stress, using a probabilistic approach. The total length of pipelines (approx. 200.000 km operational in the Netherlands) and the complexity of the model chain that is needed to calculate a chance of failure, results in large computational challenges, as it requires massive evaluation of possible scenarios to reach the required level of confidence. To cope with this, a scalable computational infrastructure has been developed, composing a model workflow in which components have a heterogeneous technological basis. Three pilot areas covering an urban, a rural and a mixed environment, characterised by different groundwater-management strategies and different overburden histories, are used to evaluate the differences in subsidence and uncertainties that come with

    approximately 55,000 miles of crude oil trunk lines (usually 8 to 24 inches in diameter) in the United States that connect regional markets. The United States also has an estimated 30,000 to 40,000 miles of small gathering lines (usually 2 to 6 inches in diameter) located primarily in Texas, Oklahoma, Louisiana, and Wyoming, with small systems in a number of other oil producing states. These small lines gather the oil from many wells, both onshore and offshore, and connect to larger trunk lines measuring 8 to 24 inches in diameter. There are approximately 95,000 miles of refined products pipelines nationwide. Refined products pipelines are found in almost every state in the United States, with the exception of some New England states. These refined product pipelines vary in size from relatively small, 8- to 12-inch-diameter lines, to up to 42 inches in diameter. The overview of pipeline design, installation, and operation provided in the following sections is only a cursory treatment. Readers interested in more detailed discussions are invited to consult the myriad engineering publications available that provide such details. The two primary publications on which the following discussions are based are: Oil and Gas Pipeline Fundamentals (Kennedy 1993) and the Pipeline Rules of Thumb Handbook (McAllister 2002). Both are recommended references for additional reading for those requiring additional details. Websites maintained by various pipeline operators also can provide much useful information, as well as links to other sources of information. In particular, the website maintained by the U.S. Department of Energy's Energy Information Administration (EIA) (http://www.eia.doe.gov) is recommended. An excellent bibliography on pipeline standards and practices, including special considerations for pipelines in Arctic climates, has been published jointly by librarians for the Alyeska Pipeline Service Company (operators of the Trans-Alaska Pipeline System [TAPS]) and the

  13. Transient leak detection in crude oil pipelines

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

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

  17. Papers of the Canadian Energy Pipeline Association's 7. annual climate change workshop : energy efficiency and greenhouse gas reduction opportunities

    International Nuclear Information System (INIS)

    2003-01-01

    This conference focused on the role that Canadian pipeline companies will play in addressing greenhouse gas emissions. Ninety-five per cent of Canada's oil and gas is transported by pipeline. The Canadian Energy Pipeline Association (CEPA) is a national association representing all the major crude oil and natural gas transportation companies in Canada which operate 100,000 kilometres of pipeline in the country. CEPA's ongoing commitment to climate change includes a commitment to participate in the climate change process, share best management practices, develop energy efficient technology, and position Canadian companies so that they can be part of the solution. It was emphasized that a strong commitment to an effective innovation strategy will be crucial to a successful long term energy policy that meets both economic and environmental objectives. One of the key messages at the conference was that Canada's climate change policies should be consistent with those of the United States, its major trading partner, to ensure that Canada is not placed at a competitive disadvantage within North American and world energy markets. It was also noted that greenhouse gas emissions should be reduced in all consuming and producing sectors of the economy through energy efficiency practices and not through reductions in Canadian industry output for domestic or export markets. Five presentations were indexed separately for inclusion in the database. tabs., figs

    2009-07-01

    Despite its common occurrence in the gas industry, black powder is a problem that is not well understood across the industry, in terms of its chemical and physical properties, source, formation, prevention or management of its impacts. 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)

    Full Text Available Companies, especially nowadays, are characterized through great mobility, fast circulation of capital, occurring in their chase for profit. In this context, companies look for alliances, economical and political assistance. These objectives can materialize through merging of companies. The merger can be internal (between Romanian companies or transboundary, which includes foreign companies. In order to correctly reflect these events, the merger operations must be regulated and must respect national and international regulations. One important request concerning the merger operations is that the accounting values of the assets, debts and ownership equity must be brought to the present financial value.

  20. Simplified Technique for Predicting Offshore Pipeline Expansion

    2018-06-01

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

    This report presented some quick facts about oil and gas pipelines in Turkey and presented opportunities for trade. The key players and customers in the oil and gas sector were described along with an export check list. Turkey is looking into becoming an energy bridge between oil and gas producing countries in the Middle East, Central Asia and Europe. The oil and gas sectors are dominated by the Turkish Petroleum Corporation, a public enterprise dealing with exploration and production, and the State Pipeline Corporation which deals with energy transmission. They are also the key buyers of oil and gas equipment in Turkey. There are several pipelines connecting countries bordering the Caspian Sea. Opportunities exist in the areas of engineering consulting as well as contracting services for oil and gas pipeline transmission and distribution. Other opportunities lie in the area of pipeline construction, rehabilitation, materials, equipment, installation, and supervisory control and data acquisition (SCADA) systems. Currently, the major players are suppliers from Italy, Germany, France, United States and Japan. Turkey has no trade barriers and imported equipment and materials are not subjected to any restriction. The oil and gas market in Turkey expected in increase by an average annual growth rate of 15 per cent from 2001 to 2003.

    This paper reports on international pipeline construction which has entered a fast-growth period, accelerated by the new political and economic realities around the world and increasing demand for natural gas, crude oil and refined petroleum products. Many projects are under way or in planning for completion in the mid- to late 1990s in Europe, South America, Asia and the Middle East. Pipeline And Gas Journal's projection calls for construction or other work on 30,700 miles of new natural gas, crude oil and refined products pipelines in the 1992-93 period outside Canada and the U.S. These projects will cost an estimated $30 billion-plus. Natural gas pipelines will comprise most of the mileage, accounting for almost 23,000 miles at an estimated cost of $26.3 billion. Products pipelines, planned or under construction, will add another 5,800 miles at a cost of $2.8 billion. Crude oil pipelines, at a minimum, will total 1,900 new miles at a cost of slightly under $1 billion

    This work deals with the analysis of the interaction of earthquakes with pipelines transporting and distributing natural gas for industrial and civil use. To this aim, a new large data-set of seismic information classified on the basis of selected seismological, geotechnical and structural parameters is presented and analyzed. Particular attention is devoted to continuous pipelines under strong ground shaking, which is the geotechnical effect due to passage of waves in soil. Results are provided in terms of the likelihood of the loss of containment with respect to Peak Ground Velocity (PGV), a seismic intensity parameter which may be easily retrieved either from local authorities and public databases or from site dependent hazard analysis. Fragility functions and seismic intensity threshold values for the failure and for the loss of containment of gas from pipeline systems are also given. The obtained functions can be easily implemented in existing codes and guidelines for industrial risk assessment, land-use planning, and for the design of public distribution network, with specific reference to Natural—Technological interaction (Na-Tech). -- Highlights: • The seismic vulnerability of natural gas pipelines is analyzed. • A collection of data for pipelines damaged by earthquake is given. • Damage states and risk states for pipelines are defined. • Consequence-based fragility formulations for the loss of containment are given • Seismic threshold values for public authority, risk assessment and gas distribution are shown

    A difference between each of the pressures in a plurality of pipelines disposed in a shroud a reactor container and a pressure outside of the shroud is detected, thereby enabling safety and reliable detection even for simultaneous rapture and leakage of the pipelines. That is, a difference between the pressure of a steam phase outside of the shroud and a pressure in each of a plurality of low pressure injection pipelines in an emergency core cooling system opened to the inside of the shroud in the reactor container is detected by a difference pressure detector for each of them. Then, an average value for each of the pressure difference is determined, which is compared with the difference pressure obtained from each of the detectors in a comparator. Then, if openings should be caused by rupture, leakage or the like in any of the pipelines, the pressure in that pipeline is lowered to a vicinity of an atmospheric pressure and at the vapor phase pressure at the lowest. If the pressure is compared with the average value by the comparator, a negative difference is caused. Accordingly, an alarming unit generates an alarm based on the pressure difference signal, thereby enabling to specify the failed pipeline and provide an announce of the failure. (I.S.)

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

    In the buried natural gas pipelines, many defects may occur by construction faults, corrosion, third-party interference and ground movement. When a segment of a pipeline is found to be defective, one of the repair methods is to remove its contents and cut out the defective segment after shutting down the pipeline. However, the cost is extremely high in terms of venting and disrupting the gas supply. Therefore, most pipeline companies have developed in-service repair methods without removing the line from service. In general, in order to avoid removing the line from service, direct deposition of weld metal, full-encirclement sleeve, patches, stopple fittings, half-sole and branch connections are required. There are three important concerns in the sleeve-repair welding like other methods of in-service repair-welding. The first concern is the possibility of burn-through which is due to the localized heating and loss of meterial strength on the inner surface of pipe during the welding process. The pipe wall may burst under internal pressure if the loss in strength is too great. The second concern is the high cooling rates by the flowing gas which quickly removes heat from the pipe wall, resulting in accelerated cooling of the weld. Such rapid cooling rates promote the formation of hard heat affected zone microstructure making these welds susceptible to hydrogen cracking. The third concern is for the load carrying ability, such as tensile strength, fracture toughness and fatigue strength. This study was taken to investigate the effect of in-service welding conditions and assess the mechanical properties for the direct deposition welding and sleeve-repair welding of in-service gas pipelines and develope the welding procedure specification for in-service pipeline repair. 81 figs., 40 tabs.

    The use of hydrogen in the energy sector of the United States is projected to increase significantly in the future. Current uses are predominantly in the petroleum refining sector, with hydrogen also being used in the manufacture of chemicals and other specialized products. Growth in hydrogen consumption is likely to appear in the refining sector, where greater quantities of hydrogen will be required as the quality of the raw crude decreases, and in the mining and processing of tar sands and other energy resources that are not currently used at a significant level. Furthermore, the use of hydrogen as a transportation fuel has been proposed both by automobile manufacturers and the federal government. Assuming that the use of hydrogen will significantly increase in the future, there would be a corresponding need to transport this material. A variety of production technologies are available for making hydrogen, and there are equally varied raw materials. Potential raw materials include natural gas, coal, nuclear fuel, and renewables such as solar, wind, or wave energy. As these raw materials are not uniformly distributed throughout the United States, it would be necessary to transport either the raw materials or the hydrogen long distances to the appropriate markets. While hydrogen may be transported in a number of possible forms, pipelines currently appear to be the most economical means of moving it in large quantities over great distances. One means of controlling hydrogen pipeline costs is to use common rights-of-way (ROWs) whenever feasible. For that reason, information on hydrogen pipelines is the focus of this document. Many of the features of hydrogen pipelines are similar to those of natural gas pipelines. Furthermore, as hydrogen pipeline networks expand, many of the same construction and operating features of natural gas networks would be replicated. As a result, the description of hydrogen pipelines will be very similar to that of natural gas pipelines

    Full Text Available Little is known about companies whose core business is selling telecommunications products that lever open source projects. Open source telecommunications (OST companies operate in markets that are very different from typical software product markets. The telecommunications market is regulated, vertically integrated, and proprietary designs and special chips are widely used. For a telecommunications product to be useful, it must interact with both access network products and core network products. Due to specifications in Service Agreements Levels, penalties for failures of telecommunications products are very high. This article shares information that is not widely known, including a list of OST companies and the open source projects on which they depend, the size and diversity of venture capital investment in OST companies, the nature of the commercial product-open source software and company-project relationships, ways in which OST companies make money, benefits and risks of OST companies, and competition between OST companies. Analysis of this information provides insights into the ways in which companies can build business models around open source software. These findings will be of interest to entrepreneurs, top management teams of incumbent companies that sell telecommunications products, and those who care about Ontario's ability to compete globally.

    1995-01-01

    This paper describes the construction of a 10.8 km long NPS16 (406 mm, 16 inch diameter) pipeline, across Skaha Lake, in the south Okanagan valley, British Columbia, Canada. The water crossing is part of the 32 km South Okanagan Natural Gas Pipeline Project (SONG) operated by BC Gas. The pipeline is located in a region dependent on year-round tourism. Therefore, the design and construction was influenced by sensitive environmental and land use concerns. From earlier studies, BC Gas identified surface tow or lay as preferred installation methods. The contractor, Fraser River Pile and Dredge departed from a conventional laybarge methodology after evaluating environmental data and assessing locally available equipment. The contractor proposed a surface tow with multiple surface tie-ins. This approach modification to the ''Surface Tow and Buoy Release Method'' (STBRM) used previously with success on relatively short underwater pipelines. A total of 10 pipe strings, up to 1 km long, were towed into position on the lake and tied-in using a floating platform. The joined pipeline was lowered to the lakebed by divers releasing buoys while tension was maintained from a winch barge at the free end of the pipeline. From analysis and field verified measurement the installation stresses were well below the allowable limits during all phases of construction. The entire construction, including mobilization and demobilization, lasted less than three months, and actual pipelaying less than three weeks. Installation was completed within budget and on schedule, without any environmental or safety related incidents. The SONG pipeline became operational in December 1994

    2009-07-01

    As subsea pipeline developments continue to move into deep and ultra-deep water locations, there is an increasing need for the accurate prediction of expected pipeline fatigue life. A significant factor that must be considered as part of this process is the fatigue damage sustained by the pipeline during installation. The magnitude of this installation-related damage is governed by a number of different agents, one of which is the dynamic behavior of the tensioner systems during pipe-laying operations. There are a variety of traditional finite element methods for representing dynamic tensioner behavior. These existing methods, while basic in nature, have been proven to provide adequate forecasts in terms of the dynamic variation in typical installation parameters such as top tension and sagbend/overbend strain. However due to the simplicity of these current approaches, some of them tend to over-estimate the frequency of tensioner pay out/in under dynamic loading. This excessive level of pay out/in motion results in the prediction of additional stress cycles at certain roller beds, which in turn leads to the prediction of unrealistic fatigue damage to the pipeline. This unwarranted fatigue damage then equates to an over-conservative value for the accumulated damage experienced by a pipeline weld during installation, and so leads to a reduction in the estimated fatigue life for the pipeline. This paper describes a novel approach to tensioner modeling which allows for greater control over the velocity of dynamic tensioner pay out/in and so provides a more accurate estimation of fatigue damage experienced by the pipeline during installation. The paper reports on a case study, as outlined in the proceeding section, in which a comparison is made between results from this new tensioner model and from a more conventional approach. The comparison considers typical installation parameters as well as an in-depth look at the predicted fatigue damage for the two methods

  15. Pipeline capacity and heavy oil markets

    International Nuclear Information System (INIS)

    Scott, G.R.

    1993-01-01

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

  16. Multi-attribute risk assessment for risk ranking of natural gas pipelines

    International Nuclear Information System (INIS)

    Brito, A.J.; Almeida, A.T. de

    2009-01-01

    The paper presents a decision model for risk assessment and for risk ranking of sections of natural gas pipelines based on multi-attribute utility theory. Pipeline hazard scenarios are surveyed and the reasons for a risk assessment model based on a multi-attribute approach are presented. Three dimensions of impact and the need to translate decision-makers' preferences into risk management decisions are highlighted. The model approaches these factors by using a multi-attribute utility function, in order to produce multi-dimensional risk measurements. By using decision analysis concepts, this model quantitatively incorporates the decision-maker's preferences and behavior regarding risk within clear and consistent risk measurements. In order to support the prioritizing of critical sections of pipeline in natural gas companies, this multi-attribute model also allows sections of pipeline to be ranked into a risk hierarchy. A numerical application based on a real case study was undertaken so that the effectiveness of the decision model could be verified

  17. An emerging methodology of slope hazard assessment for natural gas pipelines

    Zhou, Z.J.; O' Neil, G.; Rizkalla, M. [TransCanada PipeLines Ltd., Calgary, AB (Canada)

    2000-07-01

    A new slope assessment methodology has been developed by TransCanada PipeLines Ltd. in an effort to switch from a reactive to a proactive hazard management approach and to optimize maintenance expenditure. The company operates 37,000 km of natural gas gathering and transmission pipelines, portions of which traverse slopes and stream crossings. The newly developed rainfall-ground movement model provides site-specific ground movement predictions for approximately 1100 slopes and establishes a risk-ranked list of slopes upon which maintenance decisions can be based. The input to the predictive model is derived from internal and public information regarding site conditions. This information serves as input to a pipe-soil interaction model to determine the probability of pipeline failure for each slope. The ground movement for this model is limited to creep-type which is typically less than 100 mm per year. Landslides are not addressed in this paper. A system-wide database has been constructed for slopes to prioritize the slope movement hazards.

    Full Text Available Design of modern water supply systems of large cities as well as their management via renovation of hydraulic models poses time-consuming tasks to researchers, and coping with this task requires specific approaches. When tackling these tasks, water services companies come across a lot of information about various objects of water infrastructure, the majority of which is located underground. In those cases, modern computer-aided design systems containing various components come to help. These systems help to solve a wide array of problems using existing information regarding pipelines, analysis and optimization of their basic parameters. CAD software is becoming an integral part of water supply systems management in large cities, and its capabilities allow engineering and operating companies to not only collect all the necessary data concerning water supply systems in any given city, but also to conduct research aimed at improving various parameters of these systems, including optimization of their hydraulic properties which directly determine the quality of water. This paper contains the analysis of automated CAD software for hydraulic design and management of city water supply systems in order to provide safe and efficient operation of these water supply systems. Authors select the most suitable software that might be used to provide hydraulic compatibility of old and new sections of water supply ring mains after selective or continuous draw-in renovation and decrease in diameter of distribution networks against the background of water consumption decrease in the cities.

  5. Make your company a talent factory.

    Despite the great sums of money companies dedicate to talent management systems, many still struggle to fill key positions - limiting their potential for growth in the process. Virtually all the human resource executives in the authors' 2005 survey of 40 companies around the world said that their pipeline of high-potential employees was insufficient to fill strategic management roles. The survey revealed two primary reasons for this. First, the formal procedures for identifying and developing next-generation leaders have fallen out of sync with what companies need to grow or expand into new markets. To save money, for example, some firms have eliminated positions that would expose high-potential employees to a broad range of problems, thus sacrificing future development opportunities that would far outweigh any initial savings from the job cuts. Second, HR executives often have trouble keeping top leaders' attention on talent issues, despite those leaders' vigorous assertions that obtaining and keeping the best people is a major priority. If passion for that objective doesn't start at the top and infuse the culture, say the authors, talent management can easily deteriorate into the management of bureaucratic routines. Yet there are companies that can face the future with confidence. These firms don't just manage talent, they build talent factories. The authors describe the experiences of two such corporations - consumer products icon Procter & Gamble and financial services giant HSBC Group -that figured out how to develop and retain key employees and fill positions quickly to meet evolving business needs. Though each company approached talent management from a different direction, they both maintained a twin focus on functionality (rigorous talent processes that support strategic and cultural objectives) and vitality (management's emotional commitment, which is reflected in daily actions).

    Plant genomes vary in size and are highly complex with a high amount of repeats, genome duplication and tandem duplication. Gene encodes a wealth of information useful in studying organism and it is critical to have high quality and stable gene annotation. Thanks to advancement of sequencing technology, many plant species genomes have been sequenced and transcriptomes are also sequenced. To use these vastly large amounts of sequence data to make gene annotation or re-annotation in a timely fashion, an automatic pipeline is needed. JGI plant genomics gene annotation pipeline, called integrated gene call (IGC), is our effort toward this aim with aid of a RNA-seq transcriptome assembly pipeline. It utilizes several gene predictors based on homolog peptides and transcript ORFs. See Methods for detail. Here we present genome annotation of JGI flagship green plants produced by this pipeline plus Arabidopsis and rice except for chlamy which is done by a third party. The genome annotations of these species and others are used in our gene family build pipeline and accessible via JGI Phytozome portal whose URL and front page snapshot are shown below.

    Purpose: To enable rapid and accurate operator's monitoring for the state of pipelines in a BWR type reactor. Constitution: Specific symbols are attached respectively to a fluid supply source constituting the pipelines of a nuclear reactor facility, a plurality of fluid passing points and equipments to be supplied with the fluid, and a symmetrical matrix comprising these symbols in rows and columns is constituted. Then, a matrix is prepared based on detection signals for the states of the liquid supply source, equipments to be supplied with fluid and pipeline equipments by rendering the matrix elements between the signals expressing the state capable of passing the fluid as 1 and the matrix elements between the signals expressing the state incapable of passing the fluid as 0 . The matrix thus prepared in a signal procession circuit and a matrix in a memory circuit previously storing the matrix expressing the normal state of the pipelines are compared to judge the state of the pipelines in a short time and with no misjudging.

    2013-04-01

    The processing pipeline of a digital camera converts the RAW image acquired by the sensor to a representation of the original scene that should be as faithful as possible. There are mainly two modules responsible for the color-rendering accuracy of a digital camera: the former is the illuminant estimation and correction module, and the latter is the color matrix transformation aimed to adapt the color response of the sensor to a standard color space. These two modules together form what may be called the color correction pipeline. We design and test new color correction pipelines that exploit different illuminant estimation and correction algorithms that are tuned and automatically selected on the basis of the image content. Since the illuminant estimation is an ill-posed problem, illuminant correction is not error-free. An adaptive color matrix transformation module is optimized, taking into account the behavior of the first module in order to alleviate the amplification of color errors. The proposed pipelines are tested on a publicly available dataset of RAW images. Experimental results show that exploiting the cross-talks between the modules of the pipeline can lead to a higher color-rendition accuracy.

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

    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.

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

    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.

  15. Corrosion induced failure analysis of subsea pipelines

    Yang, Yongsheng; Khan, Faisal; Thodi, Premkumar; Abbassi, Rouzbeh

    2017-01-01

    Pipeline corrosion is one of the main causes of subsea pipeline failure. It is necessary to monitor and analyze pipeline condition to effectively predict likely failure. This paper presents an approach to analyze the observed abnormal events to assess the condition of subsea pipelines. First, it focuses on establishing a systematic corrosion failure model by Bow-Tie (BT) analysis, and subsequently the BT model is mapped into a Bayesian Network (BN) model. The BN model facilitates the modelling of interdependency of identified corrosion causes, as well as the updating of failure probabilities depending on the arrival of new information. Furthermore, an Object-Oriented Bayesian Network (OOBN) has been developed to better structure the network and to provide an efficient updating algorithm. Based on this OOBN model, probability updating and probability adaptation are performed at regular intervals to estimate the failure probabilities due to corrosion and potential consequences. This results in an interval-based condition assessment of subsea pipeline subjected to corrosion. The estimated failure probabilities would help prioritize action to prevent and control failures. Practical application of the developed model is demonstrated using a case study. - Highlights: • A Bow-Tie (BT) based corrosion failure model linking causation with the potential losses. • A novel Object-Oriented Bayesian Network (OOBN) based corrosion failure risk model. • Probability of failure updating and adaptation with respect to time using OOBN model. • Application of the proposed model to develop and test strategies to minimize failure risk.

    Discharges to air and sea are inevitable during precommissioning and commissioning of long subsea pipelines. Large quantities of water is pumped through the pipeline during these operations. This water is normally treated with corrosion inhibiting chemicals to minimise internal corrosion of the pipeline. Chemicals like methanol or glycol may be used to prevent hydrate formation, and will normally be discharged to sea during commissioning. In order to minimise the environmental impact of these operations, while maintaining corrosion protection, the Norwegian Statoil has been working for several years along three main routes such as to develop concepts and methods that minimise the discharged volumes, the use of the most environmentally friendly chemicals available, and to monitor and identify the effects of discharges to various marine species. 3 refs., 4 figs

    1972-10-25

    A safety installation for preventing pollution by pipelines, particularly those used for transporting liquid hydrocarbons, is described. It is applicable to any pipeline, but particularly to underground or submarine pipelines, whether made of steel, plastics, or any other material. The 4 essential objects of the invention are to insure reliable prevention of pollution of the environment due to leakage of a hydrocarbon through cracks in the pipe; to evacuate the leakage flow without delay to a vessel; to signal almost instantaneously the existence of a leak; and to effect remote control of operations by which the dynamic pressure in the pipe is cancelled. Each equipped section consists of a fluid-type jacket of plastic material which surrounds the pipe, which at its ends is sealed off. It is these seals which delimit the sections. (7 claims)

    2015-10-22

    Next-generation sequencing technologies have allowed the rapid determination of the complete genomes of many organisms. Although shotgun sequences from large genome organisms are still difficult to reconstruct perfect contigs each of which represents a full chromosome, those from small genomes have been assembled successfully into a very small number of contigs. In this study, we show that shotgun reads from phage genomes can be reconstructed into a single contig by controlling the number of read sequences used in de novo assembly. We have developed a pipeline to assemble small viral genomes with good reliability using a resampling method from shotgun data. This pipeline, named V-GAP (Viral Genome Assembly Pipeline), will contribute to the rapid genome typing of viruses, which are highly divergent, and thus will meet the increasing need for viral genome comparisons in metagenomic studies.

  1. Design Against Propagating Shear Failure in Pipelines

    Science.gov (United States)

    Leis, B. N.; Gray, J. Malcolm

    Propagating shear failure can occur in gas and certain hazardous liquid transmission pipelines, potentially leading to a large long-burning fire and/or widespread pollution, depending on the transported product. Such consequences require that the design of the pipeline and specification of the steel effectively preclude the chance of propagating shear failure. Because the phenomenology of such failures is complex, design against such occurrences historically has relied on full-scale demonstration experiments coupled with empirically calibrated analytical models. However, as economic drivers have pushed toward larger diameter higher pressure pipelines made of tough higher-strength grades, the design basis to ensure arrest has been severely compromised. Accordingly, for applications where the design basis becomes less certain, as has occurred increasing as steel grade and toughness has increased, it has become necessary to place greater reliance on the use and role of full-scale testing.

    Las Cumbres Observatory Global Telescope (LCOGT) is building and deploying a world-wide network of optical telescopes dedicated to time-domain astronomy. In the past year, we have deployed and commissioned four new 1m telescopes at McDonald Observatory, Texas and at CTIO, Chile, with more to come at SAAO, South Africa and Siding Spring Observatory, Australia. To handle these new data sources coming from the growing LCOGT network, and to serve them to end users, we have constructed a new data pipeline and Science Archive. We describe the new LCOGT pipeline, currently under development and testing, which makes use of the ORAC-DR automated recipe-based data reduction pipeline and illustrate some of the new data products. We also present the new Science Archive, which is being developed in partnership with the Infrared Processing and Analysis Center (IPAC) and show some of the new features the Science Archive provides.

    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 a pipeline project, watercourse crossings are an important environmental and technical challenge. In identifying the best crossing location and method, many factors must be taken into account such as fish habitat, access, geotechnical and hydrological issues. The aim of this paper is to present a program used in a major pipeline project to assess crossings of sensitive watercourses. This program was implemented in the Enbridge Northern Gateway project which extends from Bruderheim, Alberta, to Kitimat, British Columbia, crossing over 750 watercourses. A sensitive watercourse assessment (SWAT) team composed of a fisheries biologist, a pipeline watercourse construction specialist and other personnel carried out assessments on the 200 sensitive watercourses identified. This program led to recommendations to shift the crossing location at 40% of the sensitive sites. This project showed that setting up a SWAT team be helpful in choosing the best location, method and construction timing for a crossing.

    2018-01-09

    The Dark Energy Survey (DES) is a five-year optical imaging campaign with the goal of understanding the origin of cosmic acceleration. DES performs a 5000 square degree survey of the southern sky in five optical bands (g,r,i,z,Y) to a depth of ~24th magnitude. Contemporaneously, DES performs a deep, time-domain survey in four optical bands (g,r,i,z) over 27 square degrees. DES exposures are processed nightly with an evolving data reduction pipeline and evaluated for image quality to determine if they need to be retaken. Difference imaging and transient source detection are also performed in the time domain component nightly. On a bi-annual basis, DES exposures are reprocessed with a refined pipeline and coadded to maximize imaging depth. Here we describe the DES image processing pipeline in support of DES science, as a reference for users of archival DES data, and as a guide for future astronomical surveys.

    Next-generation sequencing technologies have allowed the rapid determination of the complete genomes of many organisms. Although shotgun sequences from large genome organisms are still difficult to reconstruct perfect contigs each of which represents a full chromosome, those from small genomes have been assembled successfully into a very small number of contigs. In this study, we show that shotgun reads from phage genomes can be reconstructed into a single contig by controlling the number of read sequences used in de novo assembly. We have developed a pipeline to assemble small viral genomes with good reliability using a resampling method from shotgun data. This pipeline, named V-GAP (Viral Genome Assembly Pipeline), will contribute to the rapid genome typing of viruses, which are highly divergent, and thus will meet the increasing need for viral genome comparisons in metagenomic studies.

  7. A management systems approach to pipeline integrity

    Abes, J. [CC Technologies Canada, Calgary, AB (Canada)

    2008-07-01

    A management systems approach to pipeline integrity was discussed in terms of accident causation models, lessons from accidents, and management systems. Accident causation models include the Heinrich domino theory; epidemiological models; event chain models; and system-based models. A review of the Bellingham pipeline accident showed that if the pipeline had not been weakened by external damage, it likely would have been able to withstand the pressure that occurred on the day of the rupture, and the accident would not have happened. It was also determined that there was inadequate inspection of excavation work during the water treatment plant project and consequently, there was a failure to identify and repair the damage done to the pipeline. The presentation also addressed other findings, such as inaccurate evaluation of in-line pipeline inspection data; failure to manage and protect the supervisory control and data acquisition system (SCADA); and ineffective management oversight of construction and activation of products terminal. The Carlsbad pipeline explosion was also presented as another example of an accident. Several violations by El Paso were cited, including failure to ensure that qualified personnel performed internal corrosion control procedures; failure to perform necessary tests for corrosion; and failure to follow procedures for continuing surveillance of its facilities. Last, the presentation provided a definition of management systems and discussed the characteristics and elements of a management system. These elements included policy and leadership commitment; organizational structure and responsibilities; management of resources; communication plan; document and records management; operational controls; management of change; and continual improvement. 1 fig.

    The possibility of having technical data regarding pipeline mechanical properties (yield strength, engineering ultimate strength and real stress-strain curve) may be of great importance for pipeline operators specially for old pipes from which there are seldom precise information. The use of portable equipment based on the ball indentation technique offers the possibility of having such properties with high accuracy and speed, without the necessity of pipe specimen removal, being only necessary a ball indentation with a maximum depth of 300{mu}m, and totally nondestructive. This paper presents the calculation methodology used for obtaining the related properties trough use of the ball indentation technique as well as the final version of portable equipment with such features, named 'Propinsitu', developed by a government-company-university partnership. Finally, initial results comparing the ball indentation tests with those derived from tension test are presented for typical API steel X42 and X60. (author)

    2016-03-01

    Virtual screening, the search for bioactive compounds via computational methods, provides a wide range of opportunities to speed up drug development and reduce the associated risks and costs. While virtual screening is already a standard practice in pharmaceutical companies, its applications in preclinical academic research still remain under-exploited, in spite of an increasing availability of dedicated free databases and software tools. In this survey, an overview of recent developments in this field is presented, focusing on free software and data repositories for screening as alternatives to their commercial counterparts, and outlining how available resources can be interlinked into a comprehensive virtual screening pipeline using typical academic computing facilities. Finally, to facilitate the set-up of corresponding pipelines, a downloadable software system is provided, using platform virtualization to integrate pre-installed screening tools and scripts for reproducible application across different operating systems. © The Author 2015.

    1999-01-01

    Financial information from TransCanada PipeLines Limited and a review of the company's 1998 operations was made available for the benefit of shareholders. TransCanada's pipeline system transports natural gas and crude oil from Western Canada Sedimentary Basin to North America's major energy markets. Net earnings from continuing operations for 1998, before unusual charges, were $575 million ($ 355 million after unusual charges) compared to $522 million for 1997. Solid performances from the energy transmission and international business, when compared to 1997, were more than offset by a decreased contribution from energy processing. TransCanada recorded integration costs of $166 million, after tax, related to the merger with NOVA in 1998, which was the major operational accomplishment during the year, creating a seamless economic energy delivery, processing and marketing system from the wellhead to the market. tabs., figs

    The procedure to generate the dynamic stresses caused by external events, necessary for the structural calculation of pipelines and components in nuclear power plants is presented. A special attention is given to the stress caused by the action of earthquakes and exterior explosions. In the dynamic analysis of pipeline and components is usually to show the stresses procedured by these events under the response spectra form. The methodology to obtain these response spectra is shown and discussed. Some pratical examples of spectra from nuclear power plant building are still shown. (E.G.) [pt

    1997-01-01

    Watercourses are naturally vulnerable to erosion but the risk is particularly acute after sub-soil and armour materials have been disturbed by trenching and backfilling during construction. Various types of erosion (river scour, river bed, river channel bed and river bank ) and the progressive removal of pipeline cover resulting from erosion were discussed. Methods of estimating the risk of progressive erosion, river avulsions and beaver dam scour, and methods of mitigating erosion at pipeline crossings such as deep burial, proper siting, conventional armouring, and a combination of bank toe protection, and upper bank vegetation cover, were described

    Maps of risk for individual environmental aspects within the protection zone of the Czech part of the Druzba crude oil pipeline (505.7 km) were developed based on a modified 'H and V index' method. Risk data were added into a GIS of the Druzba pipeline so that the system could be used as conceptual material in the field of environmental protection (a base for the new SCADA system). Considered environmental aspects were assessed in terms of their vulnerability. The criteria were defined as the vulnerability of the aquatic environment (surface waters and ground waters), the vulnerability of soil environment and the vulnerability of biotic components of the environment.

    1997-01-01

    In this paper I will review the main properties of water lubricated pipelines and explain some new features which have emerged from studies of self-lubrication of Syncrudes' bitumen froth. When heavy oils are lubricated with water, the water and oil are continuously injected into a pipeline and the water is stable when in a lubricating sheath around the oil core. In the case of bitumen froth obtained from the Alberta tar sands, the water is dispersed in the bitumen and it is liberated at the wall under shear; water injection is not necessary because the froth is self-lubricating

    The objective of this paper is to present an overview of the long distance iron ore slurry pipeline from Anglo Ferrous Brazil. Anglo Ferrous Brazil is a company of Anglo American plc that is one of the world's largest mining and natural resource company. Minas-Rio is a world class iron ore project which has been developed in Brazil aiming to produce 26.6 million tons per year of concentrate. The mine, concentrator and pump station 1 will be located in Conceicao do Mato Dentro, Minas Gerais state, and the terminal station will be located at Acu Port in Sao Joao da Barra, Rio de Janeiro state. The long distance iron ore slurry pipeline will be one of major differentials of Minas-Rio Project and its useful life was initially estimated in 20 years. The slurry pipeline has a total length of 525 kilometers and will be constructed from predominately 26 inches external diameter API 5L X70 pipes. From kilometer 314 to kilometer 480, 24 inches pipe will be installed to prevent slack flow downstream pump station 2. The pump station 1 is designed to provide the hydraulic head necessary to transport the concentrate iron ore slurry with 8 positive displacement pumps to pump station 2. The pump station 2, located 240 kilometers downstream pump station 1, is designed to operate with 10 positive displacement pumps. The valve station will be located at kilometer 347 and will be used to break the static head between pump station 2 and the terminal station during a slurry pipeline shutdown. (author)

    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

    In order to fuel China's economic growth, PetroChina began construction of the West to East Natural Gas Pipeline Project (WEPP) in 2001 to transport large quantities of natural gas reserves from the Tarim Basin in the Xinjiang Autonomous Region in far western China to markets in eastern China. The WEPP is the first large diameter, cross-country pipeline project ever constructed in China, and was the first to use automatic welding and automatic ultrasonic inspection on pipelines in China. This paper addressed the management, engineering, procurement and construction challenges of the WEPP. Upon completion of the 3,800 km, 1.016 mm mainline pipeline, construction will begin on other major facilities, such 294 km of lateral line, dual fiber optic conduits with the mainline, 1,100 km of access roads, 23 metering stations, 18 pigging stations, 10 compressor stations, 16 mountain tunnels, 16 aerial crossings, 1 crossing of the Yangtze River, 3 crossings of the Yellow River, a gas control center, and SCADA system. Houston-based Universal Ensco Inc. was awarded a contract to perform a feasibility study as well as a construction supervision contract by PetroChina for the WEPP. Universal also designed a gas turbine drive compressor station at Lunnan and an electric drive compressor station at Zhengzhou. This paper demonstrated that business in China for foreign companies in the pipeline industry is evolving and several changes can be expected as the state planned economy is reformed to a free market economy. 4 refs., 5 tabs., 17 figs.

    2002-05-06

    A saddle bag-like device, a relatively simple invention to carry weights to hold pipelines stable in wet environments, has catapulted a small Athabasca, Alberta, company to international prominence. The saddle bag is made of 100 per cent non-biodegradable material called geotextile, commonly referred to as road matting. The bags have a life expectancy of 100 years or more, easily outlasting the pipe they protect from shifting. Weighting systems are used on pipelines to achieve the negative buoyancy required to prevent them from floating out of wet ground. They are essential in wide swats of the northern areas where the oil and gas industry operates. The saddle bags replace the traditional concrete weights which have been either bolted down or set on top of the pipe. They were bulky and hard to transport, as well as difficult to place on the pipe. In contrast, the saddle bags are easy to transport and easy to install. Indeed, the production process is portable, so that the weighted saddle bags can be made at the site of the pipeline construction job involved. This makes it easier to do pipeline weighting jobs in cold weather, at remote locations or in spots where considerable travel time is involved in completing projects. Saddle Tech has recently joined forces with the giant in the weighting system world from the United States, CRC-Evans. The U.S. firm is marketing the bags under a trademarked name 'the saddle bag'. The product being used on projects in California, as well as on almost 90 per cent of wetlands pipeline work in Alberta and British Columbia. Production was 17,000 bags in the first year of operation. So far this season, more than 40,000 bags have been made and distributed throughout North America. Plans are afoot to expand and convert the production facility to an automated operation, running 24 hours a day.

  16. For the North, from the North : Enbridge perspectives on a Mackenzie Valley gas pipeline

    International Nuclear Information System (INIS)

    Porter, E.

    2000-01-01

    The increase in natural gas demand and strong gas prices are the main driving forces behind northern pipeline development. While Western Canada can supply much of the demand growth to key markets in the Pacific Northwest, California, Eastern Canada, as well as the Eastern and Midwestern U.S. it is not expected to supply all the growth. Producers are acquiring land in the Northwest Territories (NWT) and planning to increase drilling activity. In February 2000, Imperial, Gulf, Shell and Mobil entered into an agreement to study the feasibility of developing Mackenzie Delta gas, a study in which Enbridge Inc. participated. Enbridge is the major transporter of Canadian crude oil and liquids and they have a growing involvement in natural gas transmission. They also own and operate the largest gas distribution company in Canada. They have extensive Northern experience and already operate two pipelines in the NWT. The proposed 2,100 km, 36 inch pipeline will transport 1.2 bcf/d of natural gas increasing to 1.7 bcf/d with more compression. Its estimated cost is $4.2 billion. Some of the economic risks of such a project include the need for large amounts of equity, timing of market development, competing sources of gas, and stability of gas prices. The multitude of regulatory processes are also complex. Clarity is needed in many jurisdictional processes. Support of indigenous people is also crucial. A historic January 25, 2000 meeting of Aboriginal leaders of the Northwest Territories resulted in a declaration of support for a Mackenzie Valley pipeline. Protecting the permafrost is also a priority when constructing and operating a pipeline in the North. It is unlikely that Mackenzie Delta gas will flow before 7 years .13 figs

  1. Eye of the storm : Enbridge's Michigan leak and debate over the integrity of North America's sprawling network of aging pipelines

    International Nuclear Information System (INIS)

    Stastny, R.P.

    2010-01-01

    In the aftermath of Enbridge's oil spill in Michigan from a pipe break, the company may face greater scrutiny in its Northern Gateway application for a pipeline crossing British Columbia to the coast, where tankers would ship Alberta bitumen to Asia. In addition, regulators in the United States are more likely to be more diligent regarding TransCanada's Keystone pipeline expansion and extension to the U.S. Gulf Coast, where refineries wait to process Canadian bitumen. The Enbridge spill has sparked a debate over the integrity of North America's aging pipelines. Operators claim that transmission pipelines can operate for an indefinite period of time, provided that the appropriate maintenance and inspection practices are used. Repairs can include outright replacement of corroded pipe sections or less demanding in-situ repairs to damaged pipe coatings or cathode replacement. Coatings and cathodic protection protects pipelines from the external environment. Pigging and chemicals prevent internal corrosion from water, carbon dioxide, hydrogen sulphide, chlorines and other residues. Despite these maintenance and repair efforts, many of the pipes currently in the ground were engineered for a useful life of 20 or 25 years. 6 figs.

  10. Modeling and monitoring of pipelines and networks advanced tools for automatic monitoring and supervision of pipelines

    CERN Document Server

    Torres, Lizeth

    2017-01-01

    This book focuses on the analysis and design of advanced techniques for on-line automatic computational monitoring of pipelines and pipe networks. It discusses how to improve the systems’ security considering mathematical models of the flow, historical flow rate and pressure data, with the main goal of reducing the number of sensors installed along a pipeline. The techniques presented in the book have been implemented in digital systems to enhance the abilities of the pipeline network’s operators in recognizing anomalies. A real leak scenario in a Mexican water pipeline is used to illustrate the benefits of these techniques in locating the position of a leak. Intended for an interdisciplinary audience, the book addresses researchers and professionals in the areas of mechanical, civil and control engineering. It covers topics on fluid mechanics, instrumentation, automatic control, signal processing, computing, construction and diagnostic technologies.

  11. Annual compensation for pipelines in Alberta

    The Surface Rights Board (SRB) in Alberta held a hearing in November 2007 to address three issues involving a pipeline for Enbridge Pipelines (Athabasca) Inc. as well as several land owner issues in Townships 66-68 and Ranges 17-19, all west of the 4th Meridian. The issues the SRB examined were the appropriate amount (i.e. magnitude) of compensation payable under right of entry orders under consideration; the appropriate structure of the compensation award; and to whom the compensation was payable. This document presented a review by the Farmer's Advocate Office (FAO) of the published decision of the SRB. The verbatim decision and rationale used by the SRB to award annual compensation for loss and/or ongoing nuisance and inconvenience was presented. The document could be useful to landowners as they determine their negotiation strategy when faced with considering future pipeline access agreements. The document included a discussion of the context for the decision and a case review. Specific topics that were covered included the rationale for the decision; long term effects of pipeline arguments and SRB commentary; the award and determination; and what still needs to be done. It was concluded that the SRB requires evidence in order to answer several questions regarding the magnitude of any losses, and to what degree, if any, had the nuisance, inconvenience, and loss of rights already been anticipated and factored into the operator's final offer

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