    2017-11-01

    Full Text Available Energy infrastructure projects have caused various conflicts between stakeholders, particularly among the residents around construction sites and operators. The conflicts are largely due to the “Not in My Backyard” mentality associated with hazardous projects. In natural gas pipeline (NGP projects, conflicts have been increasing with the increase in a wider range of linear projects, and they have been worsening because of the lack of clear countermeasures. This study proposes an effective conflict management strategy for NGP projects in Korea. To achieve the objectives, 25 conflict drivers were identified and 143 case-based surveys were conducted to determine the causal relationship between the drivers and the level of conflict using structural equation modeling (SEM. The SEM results show that factors such as economic (e.g., decreased value of the land, construction-related (e.g., disturbance due to using the original route and site, and safety-related characteristics (e.g., concerns about explosions and accidents are the most important in understanding the causes of conflicts. Based on the causal relationship, five key strategies were proposed to manage the critical conflicts. This study can serve as a basis for implementing better conflict management plans in the future for a more sustainable project execution.

    The sound development of marine resource usage relies on a strong maritime engineering industry. The perilous marine environment poses the highest risk to all maritime work. It is therefore imperative to reduce the risk associated with maritime work by using some analytical methods other than engineering techniques. This study addresses this issue by using an integrated interpretive structure modeling (ISM) and Bayesian network (BN) approach in a risk assessment context. Mitigating or managing maritime risk relies primarily on domain expert experience and knowledge. ISM can be used to incorporate expert knowledge in a systematic manner and helps to impose order and direction on complex relationships that exist among system elements. Working with experts, this research used ISM to clearly specify an engineering risk factor relationship represented by a cause–effect diagram, which forms the structure of the BN. The expert subjective judgments were further transformed into a prior and conditional probability set to be embedded in the BN. We used the BN to evaluate the risks of two offshore pipeline projects in Taiwan. The results indicated that the BN can provide explicit risk information to support better project management. - Highlights: • We adopt an integrated method for risk assessment of offshore pipeline projects. • We conduct semi-structural interview with the experts for risk factor identification. • Interpretive structural modeling helps to form the digraph of Bayesian network (BN) • We perform the risk analysis with the experts by building a BN. • Risk evaluations of two case studies using the BN show effectiveness of the methods

    International Nuclear Information System (INIS)

    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

    A key advantage of trenchless construction methods compared with traditional open-cut methods is their ability to install or rehabilitate underground utility systems with limited disruption to the surrounding built and natural environments. The equivalent monetary values of these disruptions are commonly called social costs. Social costs are often ignored by engineers or project managers during project planning and design phases, partially because they cannot be calculated using standard estimating methods. In recent years some approaches for estimating social costs were presented. Nevertheless, the cost data needed for validation of these estimating methods is lacking. Development of such social cost databases can be accomplished by compiling relevant information reported in various case histories. This paper identifies eight most important social cost categories, presents mathematical methods for calculating them, and summarizes the social cost impacts for two pipeline construction projects. The case histories are analyzed in order to identify trends for the various social cost categories. The effectiveness of the methods used to estimate these values is also discussed. These findings are valuable for pipeline infrastructure engineers making renewal technology selection decisions by providing a more accurate process for the assessment of social costs and impacts. - Highlights: • Identified the eight most important social cost factors for pipeline construction • Presented mathematical methods for calculating those social cost factors • Summarized social cost impacts for two pipeline construction projects • Analyzed those projects to identify trends for the social cost factors

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

    The environmental assessment process is one of the most important phases in the implementation of pipeline projects. For that reason, new technologies and work procedures are used to perform the environmental assessment of areas where pipeways will be implemented. Since the quality of environmental assessment studies influences the social acceptance of projects and, consequently, the time required to obtain the environmental permits, PETROBRAS (Engenharia/IETEG/ETEG/EAMB) applies advanced technological tools to acquire remote sensing data (conventional / digital aero-surveys and satellite images), as well as software for digital image processing and integration and spatial analysis of information. Information about the physical, biological and socioeconomic environments are further verified and complemented through field trips using helicopters. This process makes it possible to identify environmentally favorable corridors to develop guidelines for the implementation of the pipeline, assuring its environmental feasibility, and produces relevant data to support the Environmental Impact Assessment Study, the Environmental Impact Assessment Report and the Risk Analysis Study. As an example of the application of this methodology, this paper presents results of the assessment of the Cacimbas / Catu gas pipeline, which is currently being permitted and is planned to be implemented in areas of high environmental complexity.

    New sequencing technologies have accelerated research on prokaryotic genomes and have made genome sequencing operations outside major genome sequencing centers routine. However, no off-the-shelf solution exists for the combined assembly, gene prediction, genome annotation and data presentation necessary to interpret sequencing data. The resulting requirement to invest significant resources into custom informatics support for genome sequencing projects remains a major impediment to the accessibility of high-throughput sequence data. We present a self-contained, automated high-throughput open source genome sequencing and computational genomics pipeline suitable for prokaryotic sequencing projects. The pipeline has been used at the Georgia Institute of Technology and the Centers for Disease Control and Prevention for the analysis of Neisseria meningitidis and Bordetella bronchiseptica genomes. The pipeline is capable of enhanced or manually assisted reference-based assembly using multiple assemblers and modes; gene predictor combining; and functional annotation of genes and gene products. Because every component of the pipeline is executed on a local machine with no need to access resources over the Internet, the pipeline is suitable for projects of a sensitive nature. Annotation of virulence-related features makes the pipeline particularly useful for projects working with pathogenic prokaryotes. The pipeline is licensed under the open-source GNU General Public License and available at the Georgia Tech Neisseria Base (http://nbase.biology.gatech.edu/). The pipeline is implemented with a combination of Perl, Bourne Shell and MySQL and is compatible with Linux and other Unix systems.

    Five case histories of river channel changes and associated pipeline exposure problems at river and stream crossings in Alberta were discussed with emphasis on the need for proactive inspection. For each case, the different hydrologic and geomorphic factors that resulted in erosion problems were reviewed and the mitigative actions that were taken to solve the problems were described. It was shown that in some cases, there are inherent difficulties in identifying potential erosion problems at the project design stage. It was also demonstrated that systematic monitoring and inspection procedures are useful for planning and implementing remedial measures before problems occur. There are many natural and anthropogenic causes of channel degradation. Upstream progressing degradation is usually the most common problem encountered at pipeline crossings in Alberta. The two main causes are both flood related. They include channel shortening by cutoffs across long meandering loops, and washout of downstream slope controls such as large beaver dams. The five case studies presented in this paper were: (1) North Saskatchewan River crossing near Drayton Valley, (2) Smoky River crossing near Grande Cache, (3) Hells Creek crossing near Grande Cache, (4) Modeste Creek crossing near Breton, and (5) Freeman River crossing near Swan Hills. It was emphasized that pipeline operators must consider past channel changes and geomorphic analysis to predict future channel instability. 15 figs.

    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.

    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

  18. Saint John lateral pipeline project: comprehensive study report

    International Nuclear Information System (INIS)

    1999-02-01

    A descripion is given of the results of an environmental impact assessment of the construction of a natural gas pipeline that will bring gas from Maritimes and Northeast Pipeline Management Ltd.'s (M and NP) main transmission pipeline to clients in Lake Utopia and Saint John, NB. It will be 110 km long, and the Saint John lateral will join the mainline approximately 2 km south of Big Kedron Lake, NB. Various institutional, industrial, commercial and residential clients will be able to access the pipeline in the future, and it is intended to be capable of future expansion for markets along its route and for markets that become economically feasible in the future. A matrix was developed that relates environmental resources to Environmental Components of Concern (ECCs), and to the rationale for exclusion/inclusion of the ECC as a Valued Environmental Component (VECs). The positive benefits of the pipeline to clients in the Saint John area include: reduced dependence on foreign oil, fuel switching and price competition, lower air emission pollution, increased energy efficiency, and a source of energy that is secure and reliable. VECs were selected based on: concerns of various stakeholders including the public, community groups, scientific parties, Aboriginal groups, government officials and agencies, relevant regulations; relevant literature; and past evaluation experiences, including future developments of the proposed study area. Further selection of the VECs required an examination of the issues picked out via scoping to determine the ways in which the overall project could affect the ECCs, and included construction, operation, decommissioning/abandonment, malfunctions and accidents of the pipeline. The phases of the project as they impacted residually and cumulatively on the VECs were evaluated, and impacts on Valued Socio-Economic Components (VSCs) were assessed also. The mitigation efforts taken will minimize the potential effects of the project on VECs and VSCs

    2012-01-01

    The large-scale diffusion of Carbon Capture and Storage (CCS) imposes the construction of a sizeable CO 2 pipeline infrastructure. This paper analyzes the conditions for a widespread adoption of CCS by a group of emitters that can be connected to a common pipeline system. It details a quantitative framework capable of assessing how the tariff structure and the regulatory constraints imposed on the pipeline operator impact the overall cost of CO 2 abatement via CCS. This modeling framework is applied to the case of a real European CO 2 pipeline project. We find that the obligation to use cross-subsidy-free pipeline tariffs has a minor impact on the minimum CO 2 price required to adopt the CCS. In contrast, the obligation to charge non-discriminatory prices can either impede the adoption of CCS or significantly raises that price. Besides, we compared two alternative regulatory frameworks for CCS pipelines: a common European organization as opposed to a collection of national regulations. The results indicate that the institutional scope of that regulation has a limited impact on the adoption of CCS compared to the detailed design of the tariff structure imposed to pipeline operators.

    Sekulic, G.; Vrbic, D.

    2004-01-01

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

    The Developing Human Connectome Project (dHCP) seeks to create the first 4-dimensional connectome of early life. Understanding this connectome in detail may provide insights into normal as well as abnormal patterns of brain development. Following established best practices adopted by the WU-MINN Human Connectome Project (HCP), and pioneered by FreeSurfer, the project utilises cortical surface-based processing pipelines. In this paper, we propose a fully automated processing pipeline for the structural Magnetic Resonance Imaging (MRI) of the developing neonatal brain. This proposed pipeline consists of a refined framework for cortical and sub-cortical volume segmentation, cortical surface extraction, and cortical surface inflation, which has been specifically designed to address considerable differences between adult and neonatal brains, as imaged using MRI. Using the proposed pipeline our results demonstrate that images collected from 465 subjects ranging from 28 to 45 weeks post-menstrual age (PMA) can be processed fully automatically; generating cortical surface models that are topologically correct, and correspond well with manual evaluations of tissue boundaries in 85% of cases. Results improve on state-of-the-art neonatal tissue segmentation models and significant errors were found in only 2% of cases, where these corresponded to subjects with high motion. Downstream, these surfaces will enhance comparisons of functional and diffusion MRI datasets, supporting the modelling of emerging patterns of brain connectivity. Copyright © 2018 Elsevier Inc.

    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

    2000-01-01

    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

    Full Text Available Horizontal Directional Drilling (HDD is commonly associated with well exploration activity, onshore road crossing, nearshore pipeline installation, and offshore pipeline crossing which requires precise alignment of two barges from one to the other. Here, the purpose of this study was to show one of the projects that was successfully performed on December 2013 for the Bukit Tua Project in East Java, Indonesia costing USD 8 Million. From this project experience, there are 6 Best Practices in HDD Offshore Project for Pipeline Crossing Application (first in region which will serve as a guide to future projects in replicating similar success. Out from 6 Best practices, there are two main recipes for success of HDD offshore for offshore crossings which are the drilling fluid also known as mud, and the Gyro Steering Tool (GST. First, mud parameter varies on case by case basis depending on the soil condition at the location where HDD will be performed. Failure to maintain the above parameters may result in catastrophic failure whereby the bore hole may collapse and pipe may get stuck underneath the seabed. Secondly, the beauty of GST is extremely accurate and unaffected by other metal anomalies during drilling process, thus ensuring the curve profile and direction of drilling are as per design throughout the whole process.

  6. The political economy of trans-Pakistan gas pipeline project: assessing the political and economic risks for India

    There is a growing realisation among Indian policy makers to consider the import of natural gas to address India's growing energy demand. Among many policy options to import natural gas, Indo-Iran overland pipeline option is considered to be effective and economical in addressing India's long-term energy demands. Such a pipeline would have to traverse Pakistani territory thereby necessitating a role for Pakistan in the pipeline project. Though security guarantees have been offered, India refuses to entertain the role of Pakistan in the project for a fear of its energy supply being disrupted in case of a military conflict with Pakistan. This paper argues that gas pipeline project is not only aimed at addressing India's energy concerns but also to further its strategic objectives. This paper contends that India, Iran and Pakistan do not have shared objective to make the overland project a political and commercial reality. India's stakes in the overland pipeline project are high as India's economic interests in the pipeline project are not in congruence with the politico-economic and strategic objectives of Iran and Pakistan.

    The U.S. Department of Energy’s (DOE) FutureGen 2.0 Program involves two projects: (1) the Oxy-Combustion Power Plant Project and (2) the CO2 Pipeline and Storage Project. This Final Technical Report is focused on the CO2 Pipeline and Storage Project. The FutureGen 2.0 CO2 Pipeline and Storage Project evolved from an initial siting and project definition effort in Phase I, into the Phase II activity consisting permitting, design development, the acquisition of land rights, facility design, and licensing and regulatory approvals. Phase II also progressed into construction packaging, construction procurement, and targeted early preparatory activities in the field. The CO2 Pipeline and Storage Project accomplishments were significant, and in some cases unprecedented. The engineering, permitting, legal, stakeholder, and commercial learnings substantially advance the nation’s understanding of commercial-scale CO2 storage in deep saline aquifers. Voluminous and significant information was obtained from the drilling and the testing program of the subsurface, and sophisticated modeling was performed that held up to a wide range of scrutiny. All designs progressed to the point of securing construction contracts or comfort letters attesting to successful negotiation of all contract terms and willing execution at the appropriate time all major project elements – pipeline, surface facilities, and subsurface – as well as operations. While the physical installation of the planned facilities did not proceed in part due to insufficient time to complete the project prior to the expiration of federal funding, the project met significant objectives prior to DOE’s closeout decision. Had additional time been available, there were no known, insurmountable obstacles that would have precluded successful construction and operation of the project. Due to the suspension of the project, site restoration activities were developed and the work was accomplished. The site restoration

    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

    By the year 2030 Europe's gas imports will have risen to approximately 200 bn m{sup 3}, necessitating the installation of new pipelines and LNG terminals. The largest growth in imports is not expected from Russia but from Africa and the Near East. An analysis of projected pipelines demonstrates these regions' contribution to securing Europe's gas supply. Because they help to establish market dominance or to fend off potential competitors these pipelines also serve corporate strategies. The most reliable supply will continue to come from Norway. By contrast, gas imports via pipelines from North Africa, Russia and the Persian Gulf all carry high risks of approximately the same degree. The greatest risks are associated with gas imports from the Caspian Sea.

    2008-01-01

    In order to cater for its high energy demand, Pakistan is planning to import natural gas through pipelines from neighboring countries. For fully utilizing the imported gas, providing it to end customers, the infrastructure of gas pipeline needs to be developed. Therefore, huge investment has been done and proposed in this sector in coming future. Considering geological, topographical, geopolitical and climatic conditions of the country, there is added risk of earthquake, landslides and floods. Due to current geopolitical situation there is a persistent threat of unrest and terrorism in the country. Instable Government policies, high rate of inflation, rapid change in material prices are also important risk factors. All these factors make the situation very complex in quantifying the risk especially for a project in which the risk impact factor rises exponentially in case of risk occurrence. In this paper, most appropriate risk classification is made based on technological, organizational, political, natural climatic, security and environmental risk factors. Effort has been made to device a simpler risk management methodology to analyze and manage risks of gas pipeline project. In the proposed risk management model Monte Carlo simulation has been used to identify critical risks. (author)

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

    The negative wave pressure method is one of the processes used to detect leaks on oil pipelines. The development of new leakage recognition processes is difficult because it is practically impossible to collect leakage pressure samples. The method of leakage feature extraction and the selection of the recognition model are also important in pipeline leakage detection. This study investigated a new feature extraction approach Singular Value Projection (SVP). It projects the singular value to a standard basis. A new pipeline recognition model based on the multi-class Support Vector Machines was also developed. It was found that SVP is a clear and concise recognition feature of the negative pressure wave. Field experiments proved that the model provided a high recognition accuracy rate. This approach to pipeline leakage detection based on the SVP and SVM has a high application value.

  19. Auction design for gas pipeline transportation capacity-The case of Nabucco and its open season

    2011-01-01

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

    International Nuclear Information System (INIS)

    2008-01-01

    In June 2007, Enbridge Pipelines Inc. applied for approval to extend Line 4 of its Mainline pipeline upstream from Hardisty to Edmonton, Alberta. The project would relieve a potential bottleneck and would also add an additional line across this segment to increase system security and flexibility. The average annual capacity of Line 4 would be 140,000 cubic metres per day. The Enbridge Mainline from Edmonton to Hardisty currently includes 3 oil pipelines, while the Enbridge Mainline downstream of Hardisty includes 4 oil pipelines. This document presented the views of the Board regarding the construction and operation of the project facilities; public and Aboriginal consultation; environmental and socio-economic matters; land matters; tolls and tariffs; and, supply, markets, financing and economics. The Board noted that the benefits of this project outweigh the burdens associated with it. The project required an environmental assessment under the Canadian Environmental Assessment Act which found that it is not likely to cause significant adverse environmental effects. In its approval of the project, the Board attached 15 conditions, including a requirement for Enbridge to file an updated Environmental Protection Plan for the Board's approval. The Board also approved Enbridge's application for its tolling method and to reactivate 3 sections of pre-existing pipeline. 3 tabs., 3 figs., 3 appendices

    India′s energy situation is characterized by increasing energy demand, high fossil fuel dependency, large import shares, and significant portion of population deprived of modern energy services. At this juncture, natural gas, being the cleanest fossil fuel with high efficiency and cost effectiveness, is expected to play an important role. India, with only 0.6% of proven world reserves, is not endowed with adequate natural gas domestically. Nevertheless, there are gas reserves in neighbouring regions which gives rise to the prospects of three cross border gas pipeline projects, namely, Iran–Pakistan–India, Turkmenistan–Afghanistan–Pakistan–India, and Myanmar–Bangladesh–India. This study is a political analysis of these pipeline projects. First, it provides justification on use of natural gas and promotion of cross border energy trade. Then it examines these three pipeline projects and analyses the security concerns, role of different actors, their positions, shifting goals, and strategies. The study develops scenarios on the basis of changing circumstances and discusses some of the pertinent issues like technology options for underground/underwater pipelines and role of private players. It also explores impact of India′s broader foreign relations and role of SAARC on the future of pipelines and proposes energy induced mutually assured protection (MAP) as a concept for regional security. -- Highlights: •We justify the need for cross border energy trade through gas pipelines for India. •We examine prospective pipeline projects—IPI, TAPI, MBI and their security issues. •We develop scenarios and analyze role of actors, their positions, and strategies. •We discuss technology and policy options for realizing these gas pipelines. •We propose energy induced mutually assured protection (MAP) for regional security

    The controversial discussion over natural gas supply in Europe has been going on for several years now; it all started with the controversy between Russia, Europe's main supplier country, and Ukraine and Belorus. The wish to reduce the dependence on Russian imports resulted in several European projects. One of them is the so-called Nabucco pipeline, which will transport natural gas from the Caspian region to Western Europe without touching Russian territory. A comprehensive view of the case study and the scenarios derived from it shows that the supply and demand situation in the European Union will be the central element of all developments. The economic efficiency of the Nabucco pipeline will depend on the implementation of efficiency strategies within the EU. In case of peak gas production, it is difficult to see how the Nabucco pipeline will be affected; it will depend largely on the regions in which natural gas production will decline the most. Cooperative regimes may develop along the Nabucco pipeline if the pipeline is viewed not only as an economic project but also as an approach to getting many actors together with maximum benefit to all. For the EU itself, the Nabucco pipeline is an important instrument for reducing dependence on Russian natural gas. However, Nabucco will compete with the NordStream pipeline that is currently being laid through the Baltic Sea. The NordStream pipeline is contraproductive in that it increases dependence on Russian natural gas. At the same time, the existing energy partnership between the EU and Russia is to be deepened. In principle, the Nabucco pipeline is a relevant approach to avoiding possible supply and dependence conflicts on a transnational level. (orig./RHM)

    2000-03-01

    For the purpose of reducing greenhouse effect gas emissions, a study was conducted of a project for repair/optimization of the Shebelinka, Dikanka-Kyiv, gas pipeline system in the Republic of Ukraine. As a result of the study, the following plans were proposed. The gas turbine compressor now in use has been used more than 30 years, and is needed to be changed due to the superannuation. Changes are needed of the equipment used for pipeline inspection, corrosion prevention equipment, damaged data collecting equipment, pressure detection automatic drive valve, etc. Further needed are a portable compressor by which repair work can be done without gas release into the atmospheric air. The investment required for repair/installation of these equipment totaled approximately 216 million dollars. This brings the reduction in greenhouse effect gas emissions of 512,000 tons/year, and the energy conservation of 103,000 tons/year of crude oil or its equivalent. These are estimated at about 10 million dollars in greenhouse effect gas reduction and at 15 million dollars in energy conservation. (NEDO)

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

    In order to improve the requirements of industrial processes, many decision support systems have been introduced in recent years. In this context, the alarm management systems have great relevance. On the other hand, the informatics revolution allowed a great increase of information concerning the operation of the industrial processes. Currently, process operators handle an excessive number of about 1.500 alarms per day. Thus, this overdose of information implies in the discredit of alarms. Then, in order to improve the operation activities of industrial processes, it is mandatory to incorporate procedures to evaluate and rationalize alarms. Since the EMMUA191 Standard is the reference guide to alarm management, but it does not specify how to execute an alarm management procedure, in this paper, a systematic procedure to evaluate alarms configurations in industrial processes is proposed. This procedure is in line with EMMUA191 and is composed by the following steps: to use statistics analyses to identify problematic alarms, such as occurrence, intermittency, correlation, and flooding calculation; to indicate problematic alarm group; and to propose a set of actions to be implemented. To validate our proposal, we present a case study in a gas pipeline plant using the BR-AlarmExpert software. (author)

  7. Prospects of natural gas demand and pipeline projects in the East Asia

    International Nuclear Information System (INIS)

    Ishii, A.

    1997-01-01

    The development of the natural gas industry in East Asia was discussed. It was predicted that by 2010, the demand for natural gas could potentially reach 80 billion cubic feet per day. This represents an 8 per cent per year growth rate from a 1995 baseline. Similarly, it was predicted that by 2010, the region's natural gas supply could potentially reach 65 billion cubic feet per day which would represent 2.5 times the supply of natural gas in 1995. The additional demand will most likely be supplied from the Middle East in the form of liquefied natural gas (LNG), from Eastern Russia through pipelines of LNG, or from North America in the form of LNG. Some gas may also be supplied from Central Asia through pipelines. The price and cost of natural gas are major uncertainties in the future of the East Asian gas demand. Pipeline projects from Russia to China were discussed. Japan and Korea are also interested in collaborating on the feasibility study with Russia and China on a 3,400 km pipeline of 60 inch diameter from the Koviktinskoye gas field through Mongolia to Beijing, Tianjin and Korea, transporting 20 to 30 billion cubic metres of gas annually. A natural gas pipeline project transporting gas from the southern edge of the Sakhalin Island to the Tokyo area was also discussed. The project would involve construction of a 2,200 km 40-48 inch pipeline, much of it undersea, transporting 6 to 12 million tonnes of liquid natural gas, annually

    This paper provides new empirical insights on the capital structure of project-financed LNG infrastructures and gas pipeline projects, by using data relating to projects whose financial close occurred between June 2004 and March 2011. Most results are consistent with the basic view of risk-averse funds suppliers. Especially, the projects located in risky countries and larger projects tend to exhibit lower debt ratios and less-concentrated equity ownerships. In addition, regasification projects appear to have a more diluted equity ownership. Methodological issues raised by the financing of these projects are also examined from a capital-budgeting perspective. In particular, the equity residual method, usually used by industrial practitioners to value these projects, should be adjusted. - Highlights: • This paper provides new empirical insights on the capital structure of project-financed LNG and gas pipeline infrastructures. • Most of our results are consistent with the basic view of risk-averse funds suppliers. • Projects located in risky countries exhibit lower debt ratios and less-concentrated equity ownerships. • Larger projects and regasification projects also have less concentrated equity ownerships. • From a capital-budgeting viewpoint, we examine methodological issues raised by the financing of these projects

    Aldakheel, Y.; Zeineldin, F.

    2007-01-01

    This paper describes a field case study on the use of a semi-buried poly-vinyl chloride (PVC) pipeline system in Al-Hassa oasis, Saudi Arabia and its contribution in improving water conservation. Deteriorated concrete canals at Al-Hassa irrigation project, enhanced irrigation water losses, and the annual cost of maintenance became uneconomical for the long term. The PVC pipes easy maintenance, durability, modification and flexibility give them the potential to be an economical alternative to replace a concrete lateral canal, P1H4, at Al-Hassa irrigation project. Due to the availability of PVC pipes at low cost in the Kingdom and their common use in irrigation, they were selected to construct a pipeline, 362 m in length. An energy head, 2.7 m of water, was used in determining the pipeline capacity and its internal diameter, using the continuity equation. Dismantling of the concrete canal and installing of the pipeline took place simultaneously without water stresses to the grown crops. The conveyance and distribution efficiencies increased by 25.3% and 25% respectively due to installation of pipeline. The water use with illegal extra siphons was reduced by 29.2% under the pipeline system. (author)

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

    Full Text Available This paper deals with application of Value Stream Mapping (VSM as a sustainable construction tool on a real construction project of installation of underground pipelines. VSM was adapted to reduce the high percentage of non-value-added activities and time wastes during each construction stage and the paper searched for an effective way to consider the cost for studied construction of underground pipeline. This paper is unique in its way that it adopts cost implementation of VSM to improve the productivity in underground pipeline projects. The data was observed and collected from site during construction, indicating the cycle time, value added and non-value added of each construction stage. The current state was built based on these details. This was an eye-opening exercise and a process management tool as a trigger for improvement. After the current state assessment, a future state is attempted by Value Stream Mapping tool balancing the resources using a Line of Balance (LOB technique. Moreover, a sustainable cost estimation model was developed during current state and future state to calculate the cost of underground pipeline construction. The result shows a cost reduction of 20.8% between current and future states. This reflects the importance of the cost based Value Stream Mapping in construction as a sustainable measurement tool. This new tool could be utilized in construction industry to add the sustainability and effective cost management.

    The developing Human Connectome Project is set to create and make available to the scientific community a 4-dimensional map of functional and structural cerebral connectivity from 20 to 44 weeks post-menstrual age, to allow exploration of the genetic and environmental influences on brain development, and the relation between connectivity and neurocognitive function. A large set of multi-modal MRI data from fetuses and newborn infants is currently being acquired, along with genetic, clinical and developmental information. In this overview, we describe the neonatal diffusion MRI (dMRI) image processing pipeline and the structural connectivity aspect of the project. Neonatal dMRI data poses specific challenges, and standard analysis techniques used for adult data are not directly applicable. We have developed a processing pipeline that deals directly with neonatal-specific issues, such as severe motion and motion-related artefacts, small brain sizes, high brain water content and reduced anisotropy. This pipeline allows automated analysis of in-vivo dMRI data, probes tissue microstructure, reconstructs a number of major white matter tracts, and includes an automated quality control framework that identifies processing issues or inconsistencies. We here describe the pipeline and present an exemplar analysis of data from 140 infants imaged at 38-44 weeks post-menstrual age. Copyright © 2018 The Authors. Published by Elsevier Inc.

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

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

    2004-01-01

    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.

    2009-12-19

    This presentation will concentrate on the design challenges, experience and learning from the SIT and offshore installation of two deepwater pipeline tie-ins using first-of-its-kind subsea technology and installation methodologies on the 'Blind Faith' project. The Blind Faith Subsea Tie-Ins join the Blind Faith oil and gas pipelines with the Canyon Chief gas pipeline and the Mountaineer oil pipeline in 5100 feet of water. Both of the Blind Faith oil and gas pipelines are terminated with conventional PLEMs providing a horizontal connector for the tie-in and a vertical connector for a future tie-in connection point. The connectors are ROV operable/installable clamp style connectors. The method of joining to the Canyon Chief oil and gas pipelines and the type of jumper employed are unique to the tie-in. An ROV operable / installable mechanical pipe end connector connects the bare ends of the Canyon Chief and Mountaineer pipelines. The mechanical pipe end connector is fitted with an integral clamp connector hub and rests on an ROV installed mud mat. After installation of the mechanical connector, metrology was performed to create a neutral state horizontal jumper for joining the mechanical connector hub and the Blind Faith PLEM. The neutral state horizontal jumper is a compliant 'Z-Bend' design. During installation the jumper was elastically pre-deformed using a bowstring system. Pre-deformation of the jumper provided installation clearances and facilitated the neutral stress state after installation. Once landed the jumper bowstring was relaxed, allowing the jumper to expand to fit between the hubs. After expansion and make-up, the clamp connectors were tightened via an ROV operated hydraulic torque wrench. A seal test verified the integrity of the connections. After installation the jumper remains in a minimal residual stress state atypical of most horizontal jumpers. The horizontal jumper was chosen over the vertical jumper because it provides a

    Full Text Available Gas pipelines pass through different topographies. Their stress level is influenced not only by gas pressure, but also by the adjacent soil, the thickness of any covering layers, and soil movements (sinking, landslides. The stress level may be unevenly spread over a pipe due to these causes. When evaluating experimental measurements, errors may occur. The value of the resistance reserve of steel can be adjusted by a detailed analysis of any loading. This reserve can be used in the assessment of a pipeline’s actual state or in reconstructions. A detailed analysis of such loading and its comparison with the simple theory of elasticity is shown in this article.

    A water-quality monitoring program was implemented for Bechtel Corporation to measure the short-term increases in turbidity in the Moyie River caused by construction activities of the Pacific Gas Transmission-Pacific Gas & Electric Pipeline Expansion Project. Construction of the buried, 42-in.-diameter, steel pipeline, during the summer of 1992, involved eight wet crossings of the Moyie River along the 13-mi section of pipeline immediately south of the Canadian-United States border in Boundary County, Idaho. This report summarizes the sampling and analysis protocol used and gives the results and observations for each of the eight crossings. The data obtained from this monitoring program, in addition to satisfying regulatory requirements for the Pipeline Expansion Project, will contribute to an ongoing long-term study of the Moyie River crossings being performed for the Gas Research Institute by Argonne National Laboratory. The purpose of this document is strictly limited to reporting the results of the monitoring program. Interpretation of the data is not within the scope of this report.

  1. Colonial pipeline Enoree River oil spill: A case history

    International Nuclear Information System (INIS)

    Smith, A.B. Jr.

    1993-01-01

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

    For pipe joints stored during large-scale offshore pipeline construction projects, corrosion protection as well as protection from physical damage of pipelines is very important. Integrity Management does not just start with the operation of a pipeline. In the past, with the much lower risks and cost at stake in on shore constriction, this factor was often overlooked. Sometimes, newly laid pipelines failed upon hydrostatic testing or even during operation. Causes were corrosion or damage the pipe joints took before pipeline laying. For offshore projects, the cost and consequences associated with such failures are orders of magnitude higher and must be avoided by all means. Within six months from the conception of the idea, a system was developed and deployed that protected (and in part still protects) a large number of pipe joints used in a European offshore gas pipeline project more than 2000 km. The pipe joints were physically protected from corrosion, interior contamination, and condensation. At the same time, the system provided real-time monitoring of more than 100'000 pipe joints stored at 5 storage yards distributed over 3 countries with distances of more than 1200 km apart from each other. Every single joint was identified with its location and status at every time during the storage period. Any third-party interference was transmitted to a central control room in real time as well. Protection of the pipe joints was provided vs.: corrosion of pipe joint end cutbacks exposed to the maritime climate for up to 2 years; contamination of the pipe interior by: foreign material, dirt, water, ice, animals. Third party damage to the pipe joints; damage to the protection system or to the transmission network; fire; theft of pipe joints or other equipment. System features were: modular pipe caps that, protect the pipe interior, cover both inner and outer cutback, allow ventilation of the pipe interior, continuously monitor each pipe joint for third party damage

    International Nuclear Information System (INIS)

    1994-01-01

    The Southeast Regional Wastewater Treatment Plant (SERWTP) Facilities Improvement Plan and Geysers Effluent Pipeline and Effluent Injection Project are proposed as a plan to provide expanded wastewater treatment capabilities and to dispose of the effluent by injection in The Geysers geothermal field for purposes of power production. The project is located predominantly in the County of Lake, California, and also in part of Sonoma County. The plan includes various conventional facilities improvements in wastewater treatment to a secondary level of treatment at the SWERWTP. The plan includes facilities to convey the treated effluent in a 26-mile, 24-inch inside diameter pipeline to the Southeast Geysers. The wastewater from the SERWTP would be supplemented by raw lake water diverted from nearby Clear Lake. At The Geysers, the effluent would be directed into a system of distribution lines to wells. In the geothermal reservoir, the water will be converted to steam and collected in production wells that will direct the steam to six existing power plants. This document is a summary of a combined full Environmental Impact Report (EIR) and Environmental Impact Statement (EIS). The EIR/EIS describes the environmental impacts of the various components of the project. Mitigation measures are suggested for reducing impacts to a less than significant level

    Full Text Available Case study of corrosion failure of urban water supply system caused by the harmful effects of stray currents was presented. The failure occurred at a site distant from the sources of these currents namely the tramway and railway traction systems. Diagnosis revealed the stray currents flow to pipeline over a remote distance of 800/1000 m from the point of failure. At the point of failure stray currents flowed from the pipeline to the ground through external insulation defects, causing the process of electrolytic corrosion of the metal. Long distance between the affected section of the pipeline and the sources of stray currents excludes the typical protection against stray currents in the form of electrical polarized drainage. Corrosion protection at this point can be achieved by using the earthing electrodes made of magnesium, which will also provide cathodic current protection as galvanic anode.

    2008-09-15

    The flexibility of the CDM is intended to reduce the cost of compliance for Annex 1 countries and contribute to cost-effective reductions. This paper provides a framework for defining cost-effective payments for CDM carbon reductions. The projects in the CDM pipeline are categorised into project types. The data provided in the Project Design Documents is quantitatively assessed to calculate the median cost and range of costs for producing a CER from the project categories. These are measured against the range of prices in the market in order to estimate the level of cost-effectiveness. Global warming potential and size of the project were shown to be key factors in the cost of producing a CER. The results show that although prices for CERs are difficult to define in the primary CER market, many of the project categories generated CERs at a cost well below the lowest market price. The difference in these two values is defined as a loss in cost-effectiveness. The CDM is shown to be successful at developing the 'lowest hanging fruit' but the mechanism could be improved to fulfil the goal of cost-effectiveness by linking the price per CER to the cost of generating a CER.

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

    Energy Technology Data Exchange (ETDEWEB)

    Mazzoldi, A.; Oldenburg, C. M.

    2013-12-17

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

    2008-04-15

    In June 2007, Enbridge Pipelines Inc. applied for approval to extend Line 4 of its Mainline pipeline upstream from Hardisty to Edmonton, Alberta. The project would relieve a potential bottleneck and would also add an additional line across this segment to increase system security and flexibility. The average annual capacity of Line 4 would be 140,000 cubic metres per day. The Enbridge Mainline from Edmonton to Hardisty currently includes 3 oil pipelines, while the Enbridge Mainline downstream of Hardisty includes 4 oil pipelines. This document presented the views of the Board regarding the construction and operation of the project facilities; public and Aboriginal consultation; environmental and socio-economic matters; land matters; tolls and tariffs; and, supply, markets, financing and economics. The Board noted that the benefits of this project outweigh the burdens associated with it. The project required an environmental assessment under the Canadian Environmental Assessment Act which found that it is not likely to cause significant adverse environmental effects. In its approval of the project, the Board attached 15 conditions, including a requirement for Enbridge to file an updated Environmental Protection Plan for the Board's approval. The Board also approved Enbridge's application for its tolling method and to reactivate 3 sections of pre-existing pipeline. 3 tabs., 3 figs., 3 appendices.

    Concerning the surrounding flora, the implementation of pipelines may cause fragmentation and isolation of the remaining natural vegetation, possibly changing the forest structure; thus raising the border effect; modifying the ratio of species and life forms, decreasing the vegetal diversity and/or causing a lack of connectivity among the remaining indigenous forest resources. In the case of pipelines, the most important environmental measure intended to mitigate the damage caused to the flora is the adoption of Indigenous Flora Rescue Programs. This paper is aimed at analyzing the programs currently applied during the implementation of the GASENE project, by conducting a case study. The main targets of such program are obtaining seeds and fruits with a view to subsidize the potential production of sapling to be further employed in the recovery of areas impacted by the pipeline works; and then relocate the most significant samples of species rescued from the suppressed areas in order to comprise forest areas adjacent to the pipeline's right-of-way. The programs had little differences in their methodology while being implemented, however, we consider that up to the present moment the results obtained in the preservation of species of native flora have been satisfactory.

    The transport of liquid or gas fluids, such as water, fuel, chemical products, minerals, among others, through underground pipelines, is becoming more significant in the whole world, specially in Brazil, due to low cost, operational security and low physical interference at the surface. By the other hand, the ambient matters, the population's security in pipeline tracing and economic aspects lead to greater requirements in relation to the integrity of those installations. Corrosion is one of the most important causes of underground pipelines' deterioration and coating and cathodic protection are recommended to prevent it from occurring. However, both techniques must be considered in the pipeline project for it to be successful. At the present work the most important kinds of coating for underground pipelines are presented, as well as the applications, limitations, reference norms and the interface with the cathodic protection systems in relation to the efficiencies to be adopted and the expected performance. Is it also discussed the welded piping joints confection and the protection difficulties when the efficiencies are not corresponded to those foreseen in the cathodic protection systems project.

    In this paper, a case study in flow assurance is performed considering an offshore operating system, using the software OLGA. As operating system we consider a pipeline-riser geometry with typical dimensions of offshore oil production systems, and a three-phase flow of oil, gas and water. The model developed in OLGA considers the composition and dimensions of the tubes, heat transfer parameters, process equipment and fluid sources. The fluids properties are calculated using the software PVTsim. Simulations are ran in order to determine the pipeline inner diameter and insulation required to satisfy pressure and temperature requirements. It is also possible to simulate the transient behavior of the system, which allows to evaluate if production instabilities are present. In case instabilities exist, two mitigation alternatives are evaluated: closure of a choke valve before the separator and gas lift. Considering a possible production shutdown, the tubes insulation is calculated in order to avoid hydrate formation. (author)

    Sequencing of microbial genomes is important because of microbial-carrying antibiotic and pathogenetic activities. However, even with the help of new assembling software, finishing a whole genome is a time-consuming task. In most bacteria, pathogenetic or antibiotic genes are carried in genomic islands. Therefore, a quick genomic island (GI) prediction method is useful for ongoing sequencing genomes. In this work, we built a Web server called GI-POP (http://gipop.life.nthu.edu.tw) which integrates a sequence assembling tool, a functional annotation pipeline, and a high-performance GI predicting module, in a support vector machine (SVM)-based method called genomic island genomic profile scanning (GI-GPS). The draft genomes of the ongoing genome projects in contigs or scaffolds can be submitted to our Web server, and it provides the functional annotation and highly probable GI-predicting results. GI-POP is a comprehensive annotation Web server designed for ongoing genome project analysis. Researchers can perform annotation and obtain pre-analytic information include possible GIs, coding/non-coding sequences and functional analysis from their draft genomes. This pre-analytic system can provide useful information for finishing a genome sequencing project. Copyright © 2012 Elsevier B.V. All rights reserved.

  18. Reasons for decision in the matter of Enbridge Pipelines Inc. Alberta Clipper expansion project : facilities and tolls and tariffs

    International Nuclear Information System (INIS)

    2008-01-01

    In May 2007, Enbridge Pipelines Inc. applied for approval to construct the Alberta Clipper Expansion Project which consists of 1074 km of oil pipeline and associated facilities between its Hardisty, Alberta terminal and the Canada/United States border near Gretna, Manitoba. The purpose of the project is to increase the takeaway capacity out of the Western Canada Sedimentary Basin (WCSB) and into PADD 2 and eastern Canadian markets. The pipeline would have an initial capacity of 71,500 cubic metres per day. The estimated cost of the project is $2 billion with a targeted in-service data for July 2010. Public hearings into the Alberta Clipper project began in November 2007 and included an oral hearing. The Board was presented with evidence from intervenors on many issues including impacts to Aboriginal peoples and the impact of the project on domestic interests. The Board reviewed the design and operation of the proposed facilities as well as routing and land requirements. Issues regarding the environment, socio-economic matters, tolls, tariffs and economics were also addressed. The Board was satisfied from the evidence that the proposed facilities are, and will be, required by the present and future public convenience and necessity. In approving the project, the Board attached several conditions, including one that requires Enbridge to conduct an emergency response exercise at its South Saskatchewan River crossing. This condition is in response to public concerns raised during the hearing process. 11 refs., 6 tabs., 5 figs., 4 appendices

    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.

    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.

    If inquiries concerning buried pipelines in case of intended excavations on private ground are neglected, this may have dramatic consequences. As an example, at Griselenghein near Ath, Belgium, excavations damaged the gas pipeline on 30 July 2004, and 18 were killed during the subsequent explosion. The contribution outlines cases in which inquiries concerning buried pipelines in case of intended excavations on private ground are obligatory. It points out regulations that come into force in case of neglect, and the potential contributory negligence of the utility if pipelines are not buried deep enough. (orig.)

    The Sao Paulo - Brasilia Pipeline (OSBRA) is a highly automated pipeline using a SCADA system which operates from a control room. A new quality management system standard was established for transportation and storage operations. The products had to be sampled on an automatic basis. This paper reports the development of an automatic sampling system (ASS) in accordance with the new quality control standard. The prototype was developed to be implemented through a human-machine interface (HMI) from the control room SCADA screens. A technical cooperation agreement(TCA) was drawn up for development of this new ASS product. The TCA was a joint cooperation between the Holding, the Operator and the cooperators. The prototype will be on-field tested at Senador Canedo tank farm to SPEC requirements. The current performance of the ASS establishes reasonable expectations for further successful development.

  5. Pipelines and salmon in northern British Columbia : potential impacts

    International Nuclear Information System (INIS)

    Levy, D.A.

    2009-10-01

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

    2008-02-15

    In March 2007, Enbridge Southern Lights (ESL) GP on behalf of Enbridge Southern Lights LP and Enbridge Pipelines Inc. (EPI) applied for approvals related to the Southern Lights Project. The first component of the project involves the construction of a pipeline to transport diluent from Chicago, Illinois to Edmonton on Line 13, an existing EPI Mainline pipeline. The second component of the project involves a Capacity Replacement Project to replace the loss of southbound capacity on the EPI Mainline system resulting from the transfer of Line 13 to diluent service. The application required Board approvals for several related project components, including the transfer of ownership of EPI's Line 13 to ESL; the removal of Line 13 from southbound crude oil delivery service; reversing the flow on Line 13 to carry diluent from the Canada/US border northbound to Edmonton, Alberta; constructing a new oil pipeline to transport light sour crude oil; physical changes and alterations to EPI's Line 2; and, appropriate tolls and tariffs. The Board determined that the Southern Lights Project is an innovative and cost-effective solution to transport diluent. The applicants demonstrated sufficient diluent shipping commitments to ensure the long term viability of the pipeline. The Board found that the proposal to build new facilities on existing EPI sites and right-of-way should minimize negative impacts on area landowners, and also judged that mitigation planned for the construction phase will minimize potential adverse effects. The Board will require ESL to conduct an emergency response exercise where Line 13 crosses the South Saskatchewan River. Ongoing discussions between the applicants and Aboriginal groups, and a Heritage Resource Discovery Contingency Plan, will reduce potential impacts to traditional use sites. Having reviewed all evidence, the Board approved applications for the Southern Lights Pipeline Project, worth an estimated $247.5 million in Canadian spending

    2016-03-01

    Bridging ImmunoGenomic Data-Analysis Workflow Gaps (BIGDAWG) is an integrated data-analysis pipeline designed for the standardized analysis of highly-polymorphic genetic data, specifically for the HLA and KIR genetic systems. Most modern genetic analysis programs are designed for the analysis of single nucleotide polymorphisms, but the highly polymorphic nature of HLA and KIR data require specialized methods of data analysis. BIGDAWG performs case-control data analyses of highly polymorphic genotype data characteristic of the HLA and KIR loci. BIGDAWG performs tests for Hardy-Weinberg equilibrium, calculates allele frequencies and bins low-frequency alleles for k×2 and 2×2 chi-squared tests, and calculates odds ratios, confidence intervals and p-values for each allele. When multi-locus genotype data are available, BIGDAWG estimates user-specified haplotypes and performs the same binning and statistical calculations for each haplotype. For the HLA loci, BIGDAWG performs the same analyses at the individual amino-acid level. Finally, BIGDAWG generates figures and tables for each of these comparisons. BIGDAWG obviates the error-prone reformatting needed to traffic data between multiple programs, and streamlines and standardizes the data-analysis process for case-control studies of highly polymorphic data. BIGDAWG has been implemented as the bigdawg R package and as a free web application at bigdawg.immunogenomics.org. Copyright © 2015 American Society for Histocompatibility and Immunogenetics.

    Italian Astronomical Archives Center (IA2) is a research infrastructure project that aims at coordinating different national and international initiatives to improve the quality of astrophysical data services. IA2 is now also involved in the PESSTO (Public ESO Spectroscopic Survey of Transient Objects) collaboration, developing a complete archiving system to store calibrated post processed data (including sensitive intermediate products), a user interface to access private data and Virtual Observatory (VO) compliant web services to access public fast reduction data via VO tools. The archive system shall rely on the PESSTO Marshall to provide file data and its associated metadata output by the PESSTO data-reduction pipeline. To harmonize the object repository, data handling and archiving system, new tools are under development. These systems must have a strong cross-interaction without increasing the complexities of any single task, in order to improve the performances of the whole system and must have a sturdy logic in order to perform all operations in coordination with the other PESSTO tools. MySQL Replication technology and triggers are used for the synchronization of new data in an efficient, fault tolerant manner. A general purpose library is under development to manage data starting from raw observations to final calibrated ones, open to the overriding of different sources, formats, management fields, storage and publication policies. Configurations for all the systems are stored in a dedicated schema (no configuration files), but can be easily updated by a planned Archiving System Configuration Interface (ASCI).

    The Southeast Regional Wastewater Treatment Plant (SERWTP) Facilities Improvement Plan and Geysers Effluent Pipeline and Effluent Injection Project are proposed as a plan to provide expanded wastewater treatment capabilities and to dispose of the effluent by injection in The Geysers geothermal field for purposes of power production. The project is located predominantly in the County of Lake, California, and also in part of Sonoma County. The plan includes various conventional facilities improvements in wastewater treatment to a secondary level of treatment at the SWERWTP. The plan includes facilities to convey the treated effluent in a 26-mile, 24-inch inside diameter pipeline to the Southeast Geysers. The wastewater from the SERWTP would be supplemented by raw lake water diverted from nearby Clear Lake. At The Geysers, the effluent would be directed into a system of distribution lines to wells. In the geothermal reservoir, the water will be converted to steam and collected in production wells that will direct the steam to six existing power plants. This document is a summary of a combined full Environmental Impact Report (EIR) and Environmental Impact Statement (EIS). The EIR/EIS describes the environmental impacts of the various components of the project. Mitigation measures are suggested for reducing impacts to a less than significant level.

    Stress corrosion cracking (SCC) is a common phenomenon that occurs on the outer surfaces of buried pipelines. This paper investigated aspects of SCC on 3 transmission pipelines on the West-East Gas Pipeline Project in China. The study was comprised of 3 different investigations: (1) an investigation of SCC cases on constructed pipelines; (2) an evaluation of SCC sensitivity of pipeline steels in typical soil environments; and (3) an analysis of soil environments and operation conditions of western pipelines. The study included a review of pipeline corrosion investigations, as well as an examination of pipeline failure cases. Investigative digs were conducted at 21 sites to test soil chemistries. Slow strain rate stress were conducted to evaluate SCC sensitivity of steel pipelines used in China. Potentiodynamic polarization tests were conducted to characterize the electrochemical behaviour of the X70 line pipe steel in different soil environments. Results of the study showed that the environmental conditions in many locations in China contributed to SCC in pipelines. SCC was observed on the surface of X70 steel pipe specimens in both marsh and saline environments. Seasonal temperature changes also contributed additional stress on pipelines. The movement of soil bodies in mountainous areas also contributed to stress and coating damage. It was concluded that proper cathodic protection can alleviate concentrations of local solutions under disbanded coatings. Overprotection of SCC will accelerate the growth of cracks and the degradation of coatings. Samples gathered from the solutions found under the disbanded coatings of pipelines will be used to form part of a reference database for predicting SCC in oil and gas pipelines in the future. 2 refs., 4 tabs., 5 figs.

    2012-05-01

    Every year noticeable amount of money is spent on fixing and replacing the damaged pipes which carry gas and fuel. Since there is a possibility for a catastrophic failure, knowing the proper time of this repair is of great importance. Because significant proportion of failures is due to wall thinning of pipes because of the corrosion, detecting the wall thinning has been a main part of nondestructive testing of pipes. There are wide variety of NDT techniques to detect this kind of defect such as conventional ultrasonic, eddy current, radiography etc. but some of these techniques, for example conventional ultrasonic needs the insulation of pipes removed and in some other cases such as radiography the test is not done at a reasonable speed. A new method of nondestructive testing of pipes which has the potential to test a long distance in a short period of time and does not need the whole insulation removed, has drawn a lot of attention. In this paper, the ability of ultrasonic guided waves for detecting corrosion in gas pipelines is experimentally investigated.

    The Rural Girls in Science (RGS) program was developed to foster the interest in science, engineering, and mathematics among rural high school girls in the state of Washington. Girls served include American Indians, Latinas, and Whites. This article provides an overview of the program and its outcomes not only for the participants (girls, teachers, counselors, and schools) but the researchers. Lessons learned from and about the participants are presented, and lessons learned from the process are discussed to illustrate how RGS moved from a focus on individuals to a focus on the school. The initial guiding concepts (self-esteem and scientific pipeline) were replaced by “possible selves” and our proposed complementary concepts: science-affirming and affirming science education.

    1993-01-01

    Prior to the construction of the Vancouver Island natural gas pipeline, concern was expressed for the potential defilement of community domestic water supplies when the construction work occurred in community watersheds. When drinking water becomes turbid from rainfall runoff passing through construction sites, the community disinfection process is rendered inefficacious. At a specified turbidity level, the water becomes too risky to drink without alternative disinfection such as boiling. This situation creates significant administrative problems for local health officials, intolerable social problems for residents and processing problems for industries which require clean water. This document is a review of the weekly environmental surveillance reports submitted by D. Tripp Biological Consultants to the B.C. Utilities Commission. The material is organized to relate construction practices with weather patterns thereby showing the resultant effects on water quality (turbidity).

    In today's world, large scale projects can no longer be managed through tradition project management tools. The reasons why traditional controls do not work effectively in such projects, is due in large by the complexity of stake holders engagement found in the project's large areas of influence. These stake holders are composed by the communities, the government, the NGOs, and other institutions that are actively present in the project's area of impact and have power to influence the project's embargo. Therefore, it becomes extremely important to manage these impacts to avoid future conflicts with these stake holders. This new concept is a systematic monitoring system that monitors the project's impacts through the use of global indicators (social, economic and environmental) that not only provide a quantitative measure of change in time, but can be further used as a benchmarking tool to compare performance between projects and companies.

    Health impact assessment (HIA) of projects, programmes and policies is increasingly recognized as a powerful methodology for mitigating negative health impacts and enhancing equitable and sustainable development, yet applications in the developing world are sparse. Here, we focus on a large infrastructure development in sub-Saharan Africa, namely the Chad-Cameroon petroleum development and pipeline project. We adapted a five-step process for HIA, consisting of (1) screening of project documents, (2) profiling of affected communities, (3) identifying priority health areas, predicting potential impacts, and proposing mitigation measures, (4) implementing interventions, and (5) monitoring and evaluation of health impacts. We found that project scoping was broad, including extensive environmental and social assessments. Innovative features of the project include the high degree of public-private partnerships, and the management of oil revenues for purposes of poverty reduction. The project also addressed occupational and public health issues, and developed and implemented measures to prevent or mitigate potential health impacts. However, there was a disproportionate emphasis on workers' health, particularly on the prevention/mitigation of construction-related injuries, sexually transmitted infections (STIs; mainly HIV/AIDS), and malaria. Health impacts among surrounding communities, and cumulative health impacts in the larger region were not considered in a comprehensive way. Concluding, there is a need for a more systemic approach to HIA and its incorporation within 'Equator Principles', which are increasingly adopted by the international financial community. This process would include clarification of corporate social responsibility beyond the project fence line in the mitigation of health problems at regional levels. Finally, we propose the establishment and running of a longitudinal demographic surveillance system, which--coupled with regular household surveys

    In December 1992, the US Department of Energy (DOE) directed that the Plutonium-Uranium Extraction (PUREX) Plant be shut down and deactivated because it was no longer needed to support the nation's production of weapons-grade plutonium. The PUREX/UO 2 Deactivation Project will establish a safe and environmentally secure configuration for the facility and preserve that configuration for 10 years. The 10-year span is used to predict future maintenance requirements and represents the estimated time needed to define, authorize, and initiate the follow-on decontamination and decommissioning activities. Accomplishing the deactivation project involves many activities. Removing major hazards, such as excess chemicals, spent fuel, and residual plutonium are major goals of the project. The scope of the PUREX Transition Project is described within

    In this paper, the authors present an approach as an overall framework for the estimation of the failure probability of pipelines based on: the results of the deterministic-probabilistic structural integrity analysis (taking into account loads, material properties, geometry, boundary conditions, crack size, and defected zone thickness), the corrosion rate, the number of defects and failure data (involved into the model via application of Bayesian method). The proposed approach is applied to estimate the failure probability of a selected part of the Lithuanian natural gas transmission network. The presented approach for the estimation of integrated failure probability is a combination of several different analyses allowing us to obtain: the critical crack's length and depth, the failure probability of the defected zone thickness, dependency of the failure probability on the age of the natural gas transmission pipeline. A model's uncertainty analysis and uncertainty propagation analysis are performed, as well. - Highlights: • Degradation mechanisms of natural gas transmission pipelines. • Fracture mechanic analysis of the pipe with crack. • Stress evaluation of the pipe with critical crack. • Deterministic-probabilistic structural integrity analysis of gas pipeline. • Integrated estimation of pipeline failure probability by Bayesian method.

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

    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

    A 30-inch crude oil pipeline system was built between Nuevo Teapa to Venta de Carpjo from 1978 to 1980. It is owned by Pemex; its total length is 570 km, and it has strategic importance in Mexico's refining capability. In this oil pipeline, various degrees of external and internal corrosion have been found, and recent incidents occurred as a result of stress corrosion cracking (SCC). This paper presents an approach for managing high pH SCC in such a pipeline: it includes a comprehensive verification excavation plan, a strict in-ditch NDT investigation protocol, statistical models to determine the probability of detection and identification, sizing tolerance analyses, and an assessment methodology that is backed up by the material testing program. All the results provided by the application of the approach lead to the development of integrity management strategies. An integrity management plan is established and refined before the next inspection.

    Five patients were found to have spontaneous delayed migration/shortening of their Pipeline Embolization Devices on follow-up angiography. The device migrated proximally in 4 patients and distally in 1 patient. One patient had a subarachnoid hemorrhage and died as a result of migration of the Pipeline Embolization Device, and another patient presented with complete MCA occlusion and was left severely disabled. Mismatch in arterial diameter between inflow and outflow vessels was a constant finding. Migration of the Pipeline Embolization Device was managed conservatively, with additional placement of the device, or with parent vessel occlusion. Obtaining complete expansion of the embolization device by using a longer device, increasing vessel coverage, using adjunctive aneurysm coiling, and avoiding dragging and stretching of the device are important preventive measures. Neurointerventionalists should be aware of this potentially fatal complication and take all necessary preventive measures.

  9. Adding new natural gas pipeline capacity during a transition toward competitive natural gas markets: the case of California

    Jimison, J.W.

    1992-01-01

    Major changes are imminent for the California natural gas market. Enlargements of interstate natural gas pipeline capacity have been proposed, to California from six producing regions in the U.S. and Canada. Planned to alleviate current constraints, the proposed new capacity, if it is all built, will exceed the projected amount required for peak day supplies for years to come, and could overturn current market dynamics and price-setting. Concurrently, the regulatory controls applying to California utilities and customers have been undergoing a profound change under guidance of the California Public Utility Commission, as have the regulations applying to interstate pipelines under the Federal Energy Regulatory Commission. Under the new rules, the risks but not necessarily the benefits of excess pipeline construction and market changes appear likely to fall on shippers and industrial customers, rather than small utility ratepayers. Disputes are under way over the entitlement of various groups to the depreciated value of some existing capacity, including the issue of pricing the new capacity on a rolled-in or incremental basis. Disputes are also likely over responsibility for the costs of other existing interstate capacity which may be idled as a result of the surplus

    Andre, H.

    2003-01-01

    This presentation included a brief historical look at pipeline proposals submitted over the years to bring Alaska and Northwest Territories gas to market. The challenges facing the early proponents of a pipeline from Prudhoe Bay to the Mackenzie Delta, such as cost, environmental impact and socio-economic impact on Aboriginals living in the Mackenzie Valley, have now been removed. Lobbying efforts by politicians in Alaska nearly succeeded in forcing an Alaska Highway gas pipeline, instead of letting market economics dictate the route. The author indicated that an Alaska pipeline would not benefit the Canadian natural gas industry, rather it would force production from the Western Canada Sedimentary Basin (WCSB) to be slashed, resulting in reduced drilling and lower royalties to government. The author suggested that Canada should not grant any permit to construct a pipeline in Canada that is destined for markets in the contiguous United States if the pipeline was in any way subsidized to disadvantage Canadian producers. The author explained why the proposal to build a standalone pipeline in the Mackenzie Valley before the Alaska Highway pipeline is not a good idea. Gas prices and pipeline tolls are the most important economic elements. The author expressed the opinion that the over the top route combined with the Mackenzie Valley route would be beneficial to both Canada and the United States for a host of reasons. figs

    This paper focuses on the cleaning methodology and operational constrains involved with the removal of black powder in a high pressure natural gas transmission pipeline. In this case, the accumulation of black powder along the pipeline system over the seven year period since it was put into service was creating significant problems in the areas of maintenance, customer relations, and cost to the pipeline operator due to clogging of filters, reduced gas flow, and penalties as result of non-compliant delivery contracts. The pipeline cleaning project consisted of running cleaning pigs or scrappers with batches of cleaning solution through each section of the pipeline while dealing with such factors as three (3) pipeline section lengths in excess of 160 kms (100 miles), gas flow velocity fluctuations, shutdowns, and gas delivery schedule requirements. The cleaning program for the entire pipeline system included the use of chemical and diesel based cleaning solution, running multiple cleaning pigs, liquid injection and separation system, mobile storage tanks, various equipment and personnel for logistical support. Upon completion of the cleaning program, the level of black powder and other solids in all pipeline sections was reduced to approximately 0.5% liquid/solid ratio and the pipeline system returned to normal optimum operation.

  12. Nation-building, industrialisation, and spectacle: Political functions of Gujarat’s Narmada pipeline project

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Since 2000 the Indian state of Gujarat has been working to construct a state-wide water grid to connect 75% of its approximately 60 million urban and rural residents to drinking water sourced from the controversial Sardar Sarovar Dam on the Narmada River. This project represents a massive undertaking – it is billed as the largest drinking water project in the world – and is part of a broader predilection toward large, concrete-heavy supply-side solutions to water insecurity across present-day India. This paper tracks the claims and narratives used to promote the project, the political context in which it has emerged, the purposes it serves and, following Ferguson (1990, the functioning of the discursive-bureaucratic 'machine' of which it is a product. The dam’s reinvention as the solution to Gujarat’s drinking water shortfall – increasingly for cities and Special Industrial Regions – reflects a concern with attracting and retaining foreign investment through the creation of socalled 'world-class' infrastructure. At the same time, this reinvention has contributed to a project of nationbuilding, while remaining cloaked in a discourse of technological neutrality. The heavy infrastructure renders visible Gujarat’s commitment to 'development' even when that promise has yet to be realised for many, while the promise of Narmada water gives Gujarat’s leaders political capital with favoured investors and political supporters. In conclusion, I suggest that the success of infrastructure mega-projects as a political tool is not intrinsically tied to their ability to achieve their technical and social objectives. Instead, the 'spectacle' of ambitious infrastructural development projects may well yield political gains that outweigh, for a time, the realworld costs of their inequity and unsustainability.

    The main purpose of this job is to present the characteristics that influenced the elaboration of the Urucu-Manaus Gas Pipeline Project and the difference between this pipeline and other pipelines already installed on the Amazon region. In this project were emphasized the aspects related to the route definition, mapping technologies that had not been utilized in our pipeline projects, the crossing of vast flooded areas, requiring specific studies, as well the minimization of the environment impacts, in this case the existence of animal species present only in this region. Other differential factor was the Rio Negro crossing, where the pipeline will be installed in the riverbed. The know-how attained with this project consolidates ever so the activity of building pipelines in tropical forest regions. (author)

    A critical appraisal has been presented of the CHOP for a large-scale energy infrastructure development project that was implemented in two of the world's poorest countries. The project is under close scrutiny from various independent monitoring groups, civil society organizations, and human rights groups. Reviewing the achievements and shortcomings permits the extraction of important lessons that will be critical for the future adoption of the CHOP in the current setting and for the implementation of additional CHOPs elsewhere in the developing world. The authors believe that the design must be flexible, efficient, and innovative so that a CHOP promptly can address pressing public health issues as they arise (eg, epidemic outbreak) and include the needs and demands of the concerned communities. An innovative feature of the current project is the high degree and mix of public-private partnerships. The project's CHOP also relies on partnerships. As elaborated elsewhere, public-private partnerships should be seen as a social experiment--they reveal promise but are not the solution for every problem. For this CHOP, the focus is on partnerships between a multinational consortium, government agencies, and international organizations. The partnerships also include civil society organizations for monitoring and evaluation and local NGOs designated for the implementation of the selected public health interventions within the CHOP. The governments and their respective health policies often form the umbrella under which the partnerships operate. With the increase in globalization, however, the importance and capacities of governments have diminished, and there is growing private-sector involvement. Private enterprise is seen as an efficient, innovative, pragmatic, and powerful means to achieve environmental and social sustainability. Experiences with the partnership configurations in the current CHOP are of importance for tackling grand challenges in global health by

    Full Text Available Following the successful implementation of the oil strategy, Azerbaijan began to define strategic objectives in relation to gas export policy. Currently, Azerbaijan is the only country in the region exporting gas to the international markets (Turkey, Russia, Georgia. For this reason, it is seen as “the provider and participant” of Southern Gas Corridor by EU. In this direction, Azerbaijan aims to be the country of an important and strategic natural gas exporter. From Shahdeniz field to the end European user, it targets to take part in the every ring of the value chain. These assumptions bring Azerbaijan to the position of a remarkable natural gas supplier for the export of large amount of gas to the European markets through Nabucco West. The implementation of the project with financial and technical capabilities of Azerbaijan and Turkey has made it a project to be realized between Turkey-Azerbaijan. TANAP means Turkey and Azerbaijan will emerge together in the European market for energy transportation. Along with Baku-Tbilisi-Ceyhan and Baku-Tbilisi-Erzurum, TANAP has reinforced Turkey’s position as a necessary energy corridor in delivering the energy resources of the Caspian Sea to the Western markets. In this paper, expected strategic and economic outcomes of TANAP are analyzed.

    A unique public/private partnership of local, state, federal, and corporate stakeholders is constructing the world`s first wastewater-to-electricity system in Lake County, California. A rare example of a genuinely {open_quotes}sustainable{close_quotes} system, three Lake County communities will recycle their treated wastewater effluent through the Geysers geothermal steamfield to produce an estimated 625,000 MWh of electricity annually from six existing geothermal power plants. The concept is shown schematically. Construction was initiated in October 1995, and as of this writing, the system is approximately 85% complete. Operational start-up is expected in October 1997. The key to the project`s success thus far has been its emphasis on cooperative action among affected stakeholders; and a broad, community-based view of solving problems rather than the traditional, narrower view of engineering-driven technical solutions. Special attention has been given to environmentally-responsive engineering design to avoid or minimize adverse environmental impacts.

    2009-05-01

    An increasing number of pipelines are constructed in remote regions affected by harsh environmental conditions where pipeline routes often cross mountain areas which are characterized by unstable grounds and where soil texture changes between winter and summer increase the probability of hazards. Third party intentional interference or accidental intrusions are a major cause of pipeline failures leading to large leaks or even explosions. Due to the long distances to be monitored and the linear nature of pipelines, distributed fiber optic sensing techniques offer significant advantages and the capability to detect and localize pipeline disturbance with great precision. Furthermore pipeline owner/operators lay fiber optic cable parallel to transmission pipelines for telecommunication purposes and at minimum additional cost monitoring capabilities can be added to the communication system. The Brillouin-based Omnisens DITEST monitoring system has been used in several long distance pipeline projects. The technique is capable of measuring strain and temperature over 100's kilometers with meter spatial resolution. Dedicated fiber optic cables have been developed for continuous strain and temperature monitoring and their deployment along the pipeline has enabled permanent and continuous pipeline ground movement, intrusion and leak detection. This paper presents a description of the fiber optic Brillouin-based DITEST sensing technique, its measurement performance and limits, while addressing future perspectives for pipeline monitoring. The description is supported by case studies and illustrated by field data.

    The discovery of transiting planets around bright stars holds the potential to greatly enhance our understanding of planetary atmospheres. The Transit Ephemeris Refinement and Monitoring Survey (TERMS) project focuses on updating the ephemerides of known exoplanets, put tighter constraints on the orbital parameters and shrink the large errors on the predicted transit windows, enabling photometric monitoring to search for a transit signature. Here, we present the revised orbital parameters and the photometric coverage during a predicted transit window of HD168443b, a massive planet orbiting the bright star HD 168443 (V = 6.92) with a period of 58.11 days. The high eccentricity of the planetary orbit (e = 0.53) significantly enhances the a-priori transit probability (3.7%) from what is expected for a circular orbit (2.5%). The transit ephemeris was updated using refined orbital parameters from additional Keck-HIRES radial velocities. The photometry obtained at the 1 m telescope in Cerro Tololo Inter-American Observatory (CTIO) and the T8 0.8 m Automated Photometric Telescope (APT) at Fairborn Observatory achieved the necessary millimag precision. The expected change in flux (0.5%) for HD168443 was not observed during the predicted transit window, thus allowing us to rule out the transit and put tighter constrains on the orbital inclination of HD168443b. Additionally, we present the software used to analyze the CTIO data. Developed by the TERMS team, this IDL based package is a fast, precise, and easy to use program which has eliminated the need for external software and command line prompts by utilizing the functionality of a graphical user interface (GUI).

  2. Optimal design of a gas transmission network: A case study of the Turkish natural gas pipeline network system

    Science.gov (United States)

    Gunes, Ersin Fatih

    Turkey is located between Europe, which has increasing demand for natural gas and the geographies of Middle East, Asia and Russia, which have rich and strong natural gas supply. Because of the geographical location, Turkey has strategic importance according to energy sources. To supply this demand, a pipeline network configuration with the optimal and efficient lengths, pressures, diameters and number of compressor stations is extremely needed. Because, Turkey has a currently working and constructed network topology, obtaining an optimal configuration of the pipelines, including an optimal number of compressor stations with optimal locations, is the focus of this study. Identifying a network design with lowest costs is important because of the high maintenance and set-up costs. The quantity of compressor stations, the pipeline segments' lengths, the diameter sizes and pressures at compressor stations, are considered to be decision variables in this study. Two existing optimization models were selected and applied to the case study of Turkey. Because of the fixed cost of investment, both models are formulated as mixed integer nonlinear programs, which require branch and bound combined with the nonlinear programming solution methods. The differences between these two models are related to some factors that can affect the network system of natural gas such as wall thickness, material balance compressor isentropic head and amount of gas to be delivered. The results obtained by these two techniques are compared with each other and with the current system. Major differences between results are costs, pressures and flow rates. These solution techniques are able to find a solution with minimum cost for each model both of which are less than the current cost of the system while satisfying all the constraints on diameter, length, flow rate and pressure. These results give the big picture of an ideal configuration for the future state network for the country of Turkey.

    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

CPS engineering promises to impact system condition monitoring for a diverse range of fields from healthcare, manufacturing, and transportation to aerospace and warfare. CPS for environment monitoring applications completely transforms human-to-human, human-to-machine and machine-to-machine interactions with the use of Internet Cloud. A recent trend is to gain assistance from mergers between virtual networking and physical actuation to reliably perform all conventional and complex sensing and communication tasks. Oil and gas pipeline monitoring provides a novel example of the benefits of CPS, providing a reliable remote monitoring platform to leverage environment, strategic and economic benefits. In this paper, we evaluate the applications and technical requirements for seamlessly integrating CPS with sensor network plane from a reliability perspective and review the strategies for communicating information between remote monitoring sites and the widely deployed sensor nodes. Related challenges and issues in network architecture design and relevant protocols are also provided with classification. This is supported by a case study on implementing reliable monitoring of oil and gas pipeline installations. Network parameters like node-discovery, node-mobility, data security, link connectivity, data aggregation, information knowledge discovery and quality of service provisioning have been reviewed.

CPS for environment monitoring applications completely transforms human-to-human, human-to-machine and machine-to-machine interactions with the use of Internet Cloud. A recent trend is to gain assistance from mergers between virtual networking and physical actuation to reliably perform all conventional and complex sensing and communication tasks. Oil and gas pipeline monitoring provides a novel example of the benefits of CPS, providing a reliable remote monitoring platform to leverage environment, strategic and economic benefits. In this paper, we evaluate the applications and technical requirements for seamlessly integrating CPS with sensor network plane from a reliability perspective and review the strategies for communicating information between remote monitoring sites and the widely deployed sensor nodes. Related challenges and issues in network architecture design and relevant protocols are also provided with classification. This is supported by a case study on implementing reliable monitoring of oil and gas pipeline installations. Network parameters like node-discovery, node-mobility, data security, link connectivity, data aggregation, information knowledge discovery and quality of service provisioning have been reviewed.

  8. 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

  9. Reasons for decision in the matter of Enbridge Pipelines (Westpur) Inc. Alida to Cromer Capacity Expansion (ACCE) Project : facilities

    International Nuclear Information System (INIS)

    2007-01-01

    In January 2007, Enbridge Pipelines (Westpur) Inc. applied to the National Energy Board to increase the capacity of the Enbridge Westpur system to transport crude oil between Alida, Saskatchewan and Cromer, Manitoba from the existing annual capacity of 25,000 cubic metres per day to 29,900 m 3 /d. This document presented a simplified illustration of Enbridge Westpur's ownership structure. The company applied for a Certificate of Public Convenience and Necessity; an exemption to filing a plan, profile and book of reference; and, a change of service and increase in maximum and operating pressure of an existing pipeline. The Board considered the application in an oral public hearing in February 2007. A draft environmental screening report (ESR) was released by the Board in May 2007 for public comment. The final ESR included comments received by the draft ESR. The Board heard evidence on safety issues; public consultation; Aboriginal issues; land and routing matters; economic considerations; and, socio-economic and environmental matters. Views of the Board and interested parties were presented. The Board approved the application to increase the capacity of the pipeline but denied the request for exemption to filing a plan, profile or book of reference. The Board approved a change of service and increase in maximum operating pressure of the existing pipeline. 3 fig., 2 appendices

  11. Pipeline protection with multi component liquid polyurethane coating systems

    Energy Technology Data Exchange (ETDEWEB)

    Kuprion, Rainer; Hornig, Maja [TIB Chemicals Ag, Mannheim (Germany)

    2009-07-01

    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.

  12. Estimating Greenhouse Gas Emissions Level of A Natural Gas PipelineCase Study from A to B Point in West Java-Indonesia

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Indonesia is one of the highest greenhouse emitters in the world. As a response of this problem, Indonesia declared the national action plan to focus on national greenhouse gas (GHG reduction by 26 % by 2020. To achieve this target, Government puts energy sector as one of the top priorities since it is the second strongest contributor to national GHG emissions. The main purpose of this paper is to apply the method of fugitive emissions calculation to the existing natural gas pipeline in Indonesia. Fugitive emissions are the major component of GHG emissions from natural gas systems and methane (CH4, the primary component of natural gas pipeline, is a potent GHG. Tiered approaches from Interstate Natural Gas Association of America (INGAA are implemented in this paper as the estimation guidelines. A case study of a natural gas pipeline system in Indonesia is analyzed to compare the GHG emissions level resulted from Tier 1 and Tier 2 methods. In these methods, the input data are pipeline length, the number of compressor stations, and the number of meter and pressure regulation stations. In this case, the GHG emissions level of Tier 2 is significantly different from Tier 1. The variation of pipeline length shows that for the length under 479.2 miles, Tier 1 gives lower amount of CO2 equivalent than Tier 2. The differences of these estimation methods and results can be furtherly developed to provide relevant information and recommendation for the Companies and Government to record the emissions level from natural gas transmission pipeline according to their needs and purposes.

    Zuleta, Edgar A. [TRANSIERRA S.A., Santa Cruz (Bolivia)

    2005-07-01

    The Yacuiba - Rio Grande Pipeline (GASYRG), located in the southern part of Bolivia, is a 432 km, 32 inches pipeline. Its ROW layout goes through three states, 6 municipalities and eight recognized Indigenous Peoples Territories. Seven of these territories belong to the Guarani people and one to the Weenhayek. An extensive Environmental Impact Assessment (EIA) was conducted prior to the construction period. The EIA included a Public Consultation and Disclosure processes. One of the key requests from every town, municipality or indigenous communities was to have as many job opportunities as possible. An other concern was regarding the application of an environmental management plan for their territories, being the reforestation a great concern. (author)

    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.

    2005-07-01

    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.

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

    Santos, Sidney Pereira dos [PETROBRAS S.A., Rio de Janeiro, RJ (Brazil); Kurz, Rainer; Lubomirsky, Matvey [Solar Turbines, San Diego, CA (United States)

    2009-12-19

    Gas pipeline projects traditionally have been designed based on load factor and steady state flow. This approach exposes project sponsors to project sustainability risks due to potential losses of revenues and transportation contract penalties related to pipeline capacity shortage as consequence of compressor unit's unavailability. Such unavailability should previously be quantified during the design phase. This paper presents a case study and a methodology that highlights the practical benefits of applying Monte Carlo simulation for the compression system availability analysis in conjunction with quantitative risk analysis and economic feasibility study. Project economics main variables and their impacts on the project NPV (Net Present Value) are evaluated with their respective statistics distribution to quantify risk and support decision makers to adopt mitigating measures to guarantee competitiveness while protecting project sponsors from otherwise unpredictable risks. This practical approach is compared to load factor approach and the results are presented and evaluated. (author)

  2. Comprehensive investigation into historical pipeline construction costs and engineering economic analysis of Alaska in-state gas pipeline

    Science.gov (United States)

    Rui, Zhenhua

    This study analyzes historical cost data of 412 pipelines and 220 compressor stations. On the basis of this analysis, the study also evaluates the feasibility of an Alaska in-state gas pipeline using Monte Carlo simulation techniques. Analysis of pipeline construction costs shows that component costs, shares of cost components, and learning rates for material and labor costs vary by diameter, length, volume, year, and location. Overall average learning rates for pipeline material and labor costs are 6.1% and 12.4%, respectively. Overall average cost shares for pipeline material, labor, miscellaneous, and right of way (ROW) are 31%, 40%, 23%, and 7%, respectively. Regression models are developed to estimate pipeline component costs for different lengths, cross-sectional areas, and locations. An analysis of inaccuracy in pipeline cost estimation demonstrates that the cost estimation of pipeline cost components is biased except for in the case of total costs. Overall overrun rates for pipeline material, labor, miscellaneous, ROW, and total costs are 4.9%, 22.4%, -0.9%, 9.1%, and 6.5%, respectively, and project size, capacity, diameter, location, and year of completion have different degrees of impacts on cost overruns of pipeline cost components. Analysis of compressor station costs shows that component costs, shares of cost components, and learning rates for material and labor costs vary in terms of capacity, year, and location. Average learning rates for compressor station material and labor costs are 12.1% and 7.48%, respectively. Overall average cost shares of material, labor, miscellaneous, and ROW are 50.6%, 27.2%, 21.5%, and 0.8%, respectively. Regression models are developed to estimate compressor station component costs in different capacities and locations. An investigation into inaccuracies in compressor station cost estimation demonstrates that the cost estimation for compressor stations is biased except for in the case of material costs.

    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)

    Ecological monitoring is a complementary component of the overall environmental management and monitoring program of any Environmental Impact Assessment (EIA) report. The monitoring method should be developed for each project phase and allow for periodic reporting and assessment of compliance with the environmental conditions and requirements of the EIA. Also, this method should incorporate a variance request program since site-specific conditions can affect construction on a daily basis and require time-critical application of alternative construction scenarios or environmental management methods integrated with alternative mitigation measures. Finally, taking full advantage of the latest information and communication technologies can enhance the quality of, and public involvement in, the environmental management program. In this paper, a landscape-scale ecological monitoring method for major construction projects is described using, as a basis, 20 months of experience on the Baku-Tbilisi-Ceyhan (BTC) Crude Oil Pipeline Project, covering Turkish Sections Lot B and Lot C. This analysis presents suggestions for improving ecological monitoring for major construction activities.

    2018-05-01

    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.

  18. Economic case for CANDU life extension projects

    International Nuclear Information System (INIS)

    Qureshi, S.; Tenev, T.; Lewi, M.

    2014-01-01

    As CANDU reactors approach their original end of design life utilities are faced with two options: to extend the operating life of the reactor by undergoing a life extension project (LEP), or to commence decommissioning activities. Recent project experience has shown that there is economic merit in extending the life of the operating reactor. There are many benefits to such a decision, the most obvious being the revenue that will be generated from the additional years of electricity production by the utility. Delays in decommissioning are also advantageous since the large costs associated with such a long-term activity are pushed into the future, thereby decreasing the net present value (NPV) of the investment. In addition, relatively few power reactors have been fully decommissioned to date and deferring this activity transfers the associated risks to others that are currently obligated to undertake decommissioning activities sooner. Candu Energy has been involved with the life extension projects of the following CANDU reactors: Point Lepreau (New Brunswick, Canada), Bruce Unit 1 and Unit 2 (Ontario, Canada), and Wolsong Unit 1 (South Korea). These reactors underwent fuel channel replacement programs in addition to replacement of major reactor components. Most recently, both Ontario Power Generation (OPG) and Nucleoelectrica Argentina Sociedad Anonima (NA-SA) have commenced work on life extension projects at the Darlington (Canada) and Embalse (Argentina) sites respectively. The experience gained from previous LEP projects allows Candu Energy to deliver future projects in a timely, efficient, and cost effective manner. (author)

    Krass, W; Kittel, A; Uhde, A

    1979-01-01

    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.

  1. MAKER2: an annotation pipeline and genome-database management tool for second-generation genome projects.

    Holt, Carson; Yandell, Mark

    2011-12-22

    Second-generation sequencing technologies are precipitating major shifts with regards to what kinds of genomes are being sequenced and how they are annotated. While the first generation of genome projects focused on well-studied model organisms, many of today's projects involve exotic organisms whose genomes are largely terra incognita. This complicates their annotation, because unlike first-generation projects, there are no pre-existing 'gold-standard' gene-models with which to train gene-finders. Improvements in genome assembly and the wide availability of mRNA-seq data are also creating opportunities to update and re-annotate previously published genome annotations. Today's genome projects are thus in need of new genome annotation tools that can meet the challenges and opportunities presented by second-generation sequencing technologies. We present MAKER2, a genome annotation and data management tool designed for second-generation genome projects. MAKER2 is a multi-threaded, parallelized application that can process second-generation datasets of virtually any size. We show that MAKER2 can produce accurate annotations for novel genomes where training-data are limited, of low quality or even non-existent. MAKER2 also provides an easy means to use mRNA-seq data to improve annotation quality; and it can use these data to update legacy annotations, significantly improving their quality. We also show that MAKER2 can evaluate the quality of genome annotations, and identify and prioritize problematic annotations for manual review. MAKER2 is the first annotation engine specifically designed for second-generation genome projects. MAKER2 scales to datasets of any size, requires little in the way of training data, and can use mRNA-seq data to improve annotation quality. It can also update and manage legacy genome annotation datasets.

    Research on orphan crops is often hindered by a lack of genomic resources. With the advent of affordable sequencing technologies, genotyping an entire genome or, for large-genome species, a representative fraction of the genome has become feasible for any crop. Nevertheless, most genotyping-by-sequencing (GBS) methods are geared towards obtaining large numbers of markers at low sequence depth, which excludes their application in heterozygous individuals. Furthermore, bioinformatics pipelines often lack the flexibility to deal with paired-end reads or to be applied in polyploid species. UGbS-Flex combines publicly available software with in-house python and perl scripts to efficiently call SNPs from genotyping-by-sequencing reads irrespective of the species' ploidy level, breeding system and availability of a reference genome. Noteworthy features of the UGbS-Flex pipeline are an ability to use paired-end reads as input, an effective approach to cluster reads across samples with enhanced outputs, and maximization of SNP calling. We demonstrate use of the pipeline for the identification of several thousand high-confidence SNPs with high representation across samples in an F 3 -derived F 2 population in the allotetraploid finger millet. Robust high-density genetic maps were constructed using the time-tested mapping program MAPMAKER which we upgraded to run efficiently and in a semi-automated manner in a Windows Command Prompt Environment. We exploited comparative GBS with one of the diploid ancestors of finger millet to assign linkage groups to subgenomes and demonstrate the presence of chromosomal rearrangements. The paper combines GBS protocol modifications, a novel flexible GBS analysis pipeline, UGbS-Flex, recommendations to maximize SNP identification, updated genetic mapping software, and the first high-density maps of finger millet. The modules used in the UGbS-Flex pipeline and for genetic mapping were applied to finger millet, an allotetraploid selfing species

    The free spanning pipelines assessment is a highlighted issue to be considered during the project and maintenance of the submarine pipelines. It is required to evaluate the fatigue life and the maximum stress due to VIV (Vortex Induced Vibration) as well as wave forces when applicable in case of shallow water. The code DNV-RP-F105 (2006) presents a methodology to calculate the fatigue life for free spanning pipelines. Such methodology however considers the pipe with no kind of defects. Nevertheless, sometimes corrosion defects are detected in periodic inspections and therefore their effects need to be taken into account in the fatigue life evaluation. The purpose of this paper thus is to present a procedure to assess the influence of the corrosion defects in the fatigue life of free spanning pipelines. Some FE analyses were performed to determine the stress concentrate factor (SCF) of the corrosion defects, which were used as input in the methodology presented in the code DNV-RP-F105 (2006). Curves of damage and so lifetime have been generated as function of the span length and water depth. As a practical application, this methodology was applied to a sub sea pipeline with several corrosion defects, localized in shallow water offshore Brazil. (author)

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

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

    International Nuclear Information System (INIS)

    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

    The goal of our project was to implement a pipeline for the systematic, computationally-driven study and optimization of microbial interactions and their effect on lignocellulose degradation and biofuel production. We specifically sought to design and construct artificial microbial consortia that could collectively degrade lignocellulose from plant biomass, and produce precursors of energy-rich biofuels. This project fits into the bigger picture goal of helping identify a sustainable strategy for the production of energy-rich biofuels that would satisfy the existing energy constraints and demand of our society. Based on the observation that complex natural microbial communities tend to be metabolically efficient and ecologically robust, we pursued the study of a microbial system in which the desired engineering function is achieved through division of labor across multiple microbial species. Our approach was aimed at bypassing the complexity of natural communities by establishing a rational approach to design small synthetic microbial consortia. Towards this goal, we combined multiple approaches, including computer modeling of ecosystem-level microbial metabolism, mass spectrometry of metabolites, genetic engineering, and experimental evolution. The microbial production of biofuels from lignocellulose is a complex, multi-step process. Microbial consortia are an ideal approach to consolidated bioprocessing: a community of microorganisms performs a wide variety of functions more efficiently and is more resilient to environmental perturbations than a microbial monoculture. Each organism we chose for this project addresses a specific challenge: lignin degradation (Pseudomonas putida); (hemi)cellulose degradation (Cellulomonas fimi); lignin degradation product demethoxylation (Methylobacterium spp); generation of biofuel lipid precursors (Yarrowia lipolytica). These organisms are genetically tractable, aerobic, and have been used in biotechnological applications

    Water leakage in drinking water distribution systems is a serious problem for many cities and a huge challenge for water utilities. An integrated system for the detection, early warning, and control of pipeline leakage has been developed and successfully used to manage the pipeline networks in selected areas of Beijing. A method based on the geographic information system has been proposed to quickly and automatically optimize the layout of the instruments which detect leaks. Methods are also proposed to estimate the probability of each pipe segment leaking (on the basis of historic leakage data), and to assist in locating the leakage points (based on leakage signals). The district metering area (DMA) strategy is used. Guidelines and a flowchart for establishing a DMA to manage the large-scale looped networks in Beijing are proposed. These different functions have been implemented into a central software system to simplify the day-to-day use of the system. In 2007 the system detected 102 non-obvious leakages (i.e., 14.2% of the total detected in Beijing) in the selected areas, which was estimated to save a total volume of 2,385,000 m3 of water. These results indicate the feasibility, efficiency and wider applicability of this system.

  6. Business Cases for Major Public Infrastructure Projects in Canada

    Full Text Available When governments announce that they are going to spend vast sums of taxpayers’ money on a new public infrastructure project, you can be certain they will praise all the terrific new benefits that the project will bring to citizens, making everyone’s life easier, safer, greener and better. But this does not tell us whether we are better off as a society, after accounting for the cost of these projects borne by taxpayers today and well into the future. In reality, there is a meaningful risk that a project undertaken without a proper business case could end up making citizens’ lives worse. That new commuter train might look sleek and shiny and seem convenient for some, but a close business case analysis of recent transit projects in Canada’s three largest cities suggests that in as many as four cases out of 21 projects, the burden of paying for the projects does not justify the public investment. In a review of thirteen recent public transit projects in the Greater Toronto and Hamilton Area (GTHA, at least three projects had benefits that fell short of the costs. Yet, all three projects went ahead (or have been funded. Only one project showed large net benefits for citizens once all considerations were accounted for. Three projects showed small net benefits – of a size that can be easily offset by a modest cost over-run. The six remaining projects did not have any publicly available business cases. In the Greater Montreal area, a review of three recent major transit projects turned up no evidence of a publicly available business case for any of them. As a result, Montrealers are in the dark as to how much benefit or value destruction the three projects are responsible for. Things are far more encouraging in Vancouver, however, where three out of the five major transit projects undertaken or funded in recent years were backed by business cases showing a net benefit. Only one project did not show a net benefit and one project did not have a

  9. From cases to projects in problem-based medical education

    Directory of Open Access Journals (Sweden)

    Diana Stentoft

    2014-06-01

    Full Text Available Problem-based learning (PBL based on patient cases has become a well-established worldwide educational approach in medical education. Recent studies indicate that case-based PBL when used throughout an entire curriculum may develop into a counter-productive routine for students as well as teachers. Consequently, there is a need to develop PBL approaches further allowing students to work with more ill-defined problems and alternative learning structures. In this paper, we argue that this can be realised by introducing project-PBL into the medical curriculum, as in the medical education at Aalborg University, Denmark. We outline organisations of case- and project- PBL in the medical curriculum and present an explorative study of 116 first and second year students’ experiences working in the two settings of PBL. Results reveal that students generally rate their PBL experiences positively however, project-PBL is rated more positively than case-PBL on all parameters studied. These results invite further consideration of the differences in working with cases and projects. Two central differences are discussed; the nature of the problem as the trigger of learning and students' possibilities for directing their own learning processes. The study demonstrates that introducing project-PBL may contribute significantly in problem-based medical education. However, the need for extensive research into advantages and limitations of the combined use of case- and project-PBL is also emphasised.

    The involvement of the Calgary-based company NOVA Gas International (NGI) in Malaysia's peninsular gas utilization (PGU) project, was described. Phase I and II of the project involved linking onshore gas processing plants with a natural gas transmission system. Phase III of the PGU project was a gas transmission pipeline that began midway up the west coast of peninsular Malaysia to the Malaysia-Thailand border. The complex 549 km pipeline included route selection, survey and soil investigation, archaeological study, environmental impact assessment, land acquisition, meter-station construction, telecommunication systems and office buildings. NGI was the prime contractor on the project through a joint venture with OGP Technical Services, jointly owned by NGI and Petronas, the Thai state oil company. Much of NGI's success was attributed to excellent interpersonal skills, particularly NGI's ability to build confidence and credibility with its Thai partners

    The ISL project on the Straz deposit, located about 90 km north of Prague, the capital of the Czech Republic, is the only commercial in situe leaching plant, that has been operated in the Czech Republic. The facility began its first industrial production at the end of 1969, some 5 years after the discovery of the sandstone-hosted uranium deposits in the northern part of the Bohemian Cretaceous basin. The orebodies lie 180 to 280 m below the surface, depending on its configuration. The orebodies are situated in the lower part of the Cenomanian sediments - in brackish sediments, and especially in marine sandstones. At present, the leaching fields have the area of about 650 ha (6.5 km 2 ). Some of these fields were closed, wells decommissioned and surface is being reclaimed. Because of the technological properties of uranium ores and host rocks, the leaching is very slow. Therefore some leaching fields have been in production for more than 25 years and they still produce industrial amounts of uranium. The plants were constructed for the capacity of 30 to 40 m 3 /minute (400 to 650 litres per second). The highest annual production was more than 800 tonnes. The total amount of produced uranium was 15,000 tonnes between 1968 and 1994. (author)

    Full Text Available Flooding is a consequence of the prevailing meteorological situation, the intensity and duration of precipitation, geomorphology, human activities over a geographical region and other factors. Floods result in damage and destruction of infrastructure and private property and, in some cases, in fatalities. Flash floods are sudden and quite localized in extend, characterized by excessive amounts of rainfall within a short period of time and are distinguished from other floods by their degree of severity. The broader knowledge concerning flash floods is useful for the better understanding of the underlying thermodynamic and dynamic mechanisms, as well as the associated physical processes. The wider understanding of flashfloods can form part of an integrated system for short and very short forecasting of these events. In the present study, the synoptic, dynamic and thermodynamic conditions during the development of a baroclinic depression which affected the area of Cyprus on 6 November 2005 are studied. The depression was associated with extreme weather phenomena, such as thunderstorms, a water spout and high precipitation accumulations. The results indicate the importance of the dynamic parameters in the system's development and the thermodynamic analysis has shown the convective potential of the atmosphere.

    Work of heavy equipment or vehicles above existent right-of-ways, may cause undesired external overload at buried pipelines in operation. The effect of these loads shall be analyzed considering the deflections and stresses on the pipelines. The major variables, nominal diameter, thickness, material, soil parameters, operation pressure and external loads shall be related and verified according to the limits from original project. Cases when the external loads cause higher efforts, the traffic over the pipelines shall be restricted in order to avoid damages. In other cases, it may be adapted to any technical alternatives to modify the parameters in such a way to make possible work above the right-of-way, such as increase the machine support area, increase backfill covering, a reduction in the internal operation pressure in a short time, etc. This work presents the study on the parameters used to establish the maximum allowable external loads over buried pipelines in operation.

    Full Text Available This work intends to present the environmental conflict initiated due to the installation of pipeline Ferrous Ressources S / A, in the micro region of Viçosa-MG, building an analysis of the positioning of the main social actors involved, as well as their respective relations of power. Thepipeline of Ferrous will connect the complex Beam Mine in Congonhas-MG, the port of Ferrous Ressources in Presidente Kennedy-ES in order to export iron ore. To do so, were used as methodological procedures: bibliographical research; document analysis; semi-structured interviews with different actors; and follow-up meetings of the Popular Campaign Against the Water and Pipeline Ferrous, public hearings and demonstrations taken place in the Viçosa. Furthermore, there was monitoring of the pipeline discussion in local newspapers and on blogs. Thus, this study demonstrated that the Ferrous company, which owns high economic and symbolic power, assumes the role of dominating the conflict. On the other hand, those affected and social movements against the construction of the project, are sometimes in the role of dominated, leaving them to articulate strategies of resistance to delay / stop the construction of the pipeline. The state, in turn, assumes different roles in this context, demonstrating thereby weakness in mediation and conflict management established by pipeline Ferrous mainly in the micro region of Viçosa-MG.

    Blood-blister like aneurysms (BBAs) are challenging lesions because of their wide fragile neck. Flow-diverting stents (FDSs), such as the Pipeline Embolization Device (PED), have been applied to treat BBAs less amenable to more established techniques of treatment. However, the use of FDSs, including the PED, in acute subarachnoid hemorrhage (SAH) still remains controversial. We report a case of aneurysm regrowth following PED application for a ruptured BBA that overlapped the origin of the dominant posterior communicating artery (PCoA), which was successfully treated after coil trapping of the origin of the fetal-type PCoA. And, we discuss the clinical significance of the fetal-type PCoA communicating with a BBA in terms of PED failure.

    This work concerns in the development of a study on mapping and detection of structures and geological and geotechnical features associated with karstic relief and its implications in terms of ground stability to support the pipeline as well as from the point of view of cavities / caves conservation, potentially impacted by this activity. The limited mobility of track, carried by the existing restrictions, make the route of the Cacimbas-Catu pipeline pass through the cities of Itapebi (BA), Belomonte (BA), Mascote (BA) e Camaca (BA), where the local geology is characterized by rocks of Rio Pardo Group, dating from the Superior proterozoic (lower sequence predominantly carbonatic and upper sequence predominantly terrigenous). The study included a survey of secondary data, a field survey confirming karstic features, a 2D and subsequently 3D tomography survey, and a drilling survey to direct research at points of geo-electrical anomalies. The work did not identify underground cavities on the Cacimbas-Catu pipeline route. Even taking the studies presented geo-electric anomalies the direct investigation did not confirm the presence of voids in sub-surface, which enables the implementation of pipelines in this place, however the presence of electric anomalies with high resistivity indicate geotechnical areas where special care should be taken in relation to the stability of the ground.

    The Bolivia-Brazil Natural Gas Pipeline with 2,600 kilometers of extension from Rio Grande City in Bolivia down to Canoas City, in Brazil s south. The pipeline crosses quite a few types of geological fields and topography. The pipeline's south section is quite interesting due of its bumpy topography combined with a variety of geological materials, such as, colluviums deposits and landslide areas. Curriola River at kilometer 408 of the pipeline, east region of Parana's State, crosses inclination slopes as steeply as 40 degrees. A superficial drainage system was built in order to prevent soil's motions. Every year, during the rainy season, that system was incapable of a properly drainage, generating tension cracks mainly because the embankment is more than 6 meters high. This paper's goal is to present a historical case including some site characterization, with all the mechanical investigation made, including mechanical stresses status, residual stresses assessment and a total combined stress decompose attempt into its components and how they were used to support the studies for the slope stabilization and gas pipeline integrity.

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

    Full Text Available Facing the current socio-economic contingency while guaranteeing a high level of care quality is particularly challenging in the field of healthcare. Through an integrated adoption of emerging managerial solutions, projects that allow organizations to achieve both efficiency and patient safety improvements could be implemented, thereby transposing policy directives towards a safer and more sustainable healthcare system. Therefore, the purpose of this paper is to investigate the features of Lean & Safety (L&S projects. Three Health Lean Management (HLM projects that had unexpected patient safety results were selected from the same region. Differences and similarities among the cases have been highlighted and interesting points of evidence have been noted. Despite the fact that the projects were pursuing similar objectives and benefiting from comparable support, the obtained changes had direct impact on patient safety enhancement in the cases that involved the front-office processes, and an indirect impact on patient safely for the L&S project that focused on back-office activities. The implementation processes and the Information and Communication Technologies (ICT adoption of the cases are also different.

    Full Text Available In many cases, temporary websites may be simple, accessible solutions for knowledge management and dissemination of information. However, such sites may become outdated as the funding ends, but yet in many cases, still publicly available through the Internet. The issue of website sustainability is a relevant topic for all organizations that have websites. Website lifecycle, knowledge management, and website sustainability issues are discussed through a theoretical-based literature review. These issues are then summarized and used as lessons learned for the case study approach of this paper. The aim is to identify a solution to address a website’s life and longevity, post project. A practical case study assessment of the issue of project website sustainability is needed to address the website’s longevity—post project—as creation is often made through temporary endeavors. Recommendations for future project websites are made as the outcomes and results of this study and are expressed in the form of suggested practices for project website sustainability in future projects.

    Construction industry in India is growing at a rapid pace. Along with this growth, the industry is facing numerous challenges that are making delivery of projects inefficient. Experts believe that capacity constraints in the industry need to be addressed immediately. Government has recommended `introduction of efficient technologies and modern management techniques' to increase the productivity of the industry. In this context, lean principles can act as a lever to make project delivery more efficient and provide the much needed impetus to the Indian construction sector. Around the globe lean principles are showing positive results on the projects. Project teams are reporting improvements in construction time, cost and quality along with softer benefits of enhanced collaboration, coordination and trust in project teams. Can adoption of lean principles provide similar benefits in the Indian construction sector? This research was conducted to answer this question. Using an action research approach a key lean construction tool called Last Planner System (LPS) was tested on a large Indian construction project. The work described in this work investigates the improvements achieved in project delivery by adopting LPS in Indian construction sector. Comparison in pre- and post-implementation data demonstrates increase in the certainty of work-flow and improves schedule compliance. This is measured through a simple LPS metric called percent plan complete. Explicit improvements in schedule performance are seen during 8 week LPS implementation along with implicit improvements in coordination, collaboration and trust in the project team. This work reports the findings of LPS implementation on the case study project outlining the barriers and drivers to adoption, strategies needed to ensure successful implementation and roadmap for implementation. Based on the findings the authors envision that lean construction can make project delivery more efficient in India.

    The global demand for water transmission and service pipelines is expected to more than double between 2012 and 2022. This study compared the carbon footprint of the two most common materials used for large-diameter water transmission pipelines, steel pipe (SP) and prestressed concrete cylinder pipe (PCCP). A planned water transmission pipeline in Texas was used as a case study. Four life-cycle phases for each material were considered: material production and pipeline fabrication, pipe transportation to the job site, pipe installation in the trench, and operation of the pipeline. In each phase, the energy consumed and the CO2-equivalent emissions were quantified. It was found that pipe manufacturing consumed a large amount of energy, and thus contributed more than 90% of life cycle carbon emissions for both kinds of pipe. Steel pipe had 64% larger CO2-eq emissions from manufacturing compared to PCCP. For the transportation phase, PCCP consumed more fuel due to its heavy weight, and therefore had larger CO2-eq emissions. Fuel consumption by construction equipment for installation of pipe was found to be similar for steel pipe and PCCP. Overall, steel had a 32% larger footprint due to greater energy used during manufacturing. This study compared the carbon footprint of two large-diameter water transmission pipeline materials, steel and prestressed concrete cylinder, considering four life-cycle phases for each. The study provides information that project managers can incorporate into their decision-making process concerning pipeline materials. It also provides information concerning the most important phases of the pipeline life cycle to target for emission reductions.

    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.

    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)

    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

    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.

    Award of the degree MD has special relevance in Germany since the underlying research project can be started during the qualification for admission to doctoral training. This leads to a large number of thesis projects with a not always sufficiently pronounced enthusiasm and thus poor chances of success. Accordingly a case control study was undertaken in the Department of Human Medicine, Witten/Herdecke University to investigate reported drop-outs of thesis projects. In autumn 2012 all students in the clinical phases of human medicine education were surveyed using a self-conceived questionnaire on previously initiated or terminated thesis projects, "terminated" is defined as the unsuccessful ending of a project after working for at least 3 months. Individually reported thesis terminations were evaluated using defined items in a 4-stage Likert scale regarding thesis plan and project, subsequently, graduate students who successfully completed a project received the same questionnaire. The items possibly corresponding to process determinants were averaged to a total of 7 dimensions prior to the analysis; the resulting scores were normalised in value ranges 0.0 to 1.0 (1.0 = optimal project situation) whereby individual items could be included in several scores. By means of 5 items a primary endpoint from the faculty's perspective on "compliance with formal procedures" was aggregated; by means of a two-sided Wilcoxon test at the 5 % level students with unsuccessful and successful courses were compared along the corresponding scores. 181 of 276 students from 7 study semesters participated in the screening; details of 17 terminations and 23 currently successful courses could be evaluated in the case control study.

    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.)

    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.

    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

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

    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

    results show that, in not considering material uncertainty (resource buffers, projects schedules have the potential for approximately a 5% schedule growth with the accompanying delay charges. The findings have far-reaching applications for both oil and gas and other sectors. This CCPM case-study exemplifies that the material management method represents an opportunity for industry to administrate pipeline installation projects more effectively, eliminate project duration extension, develop schedule-based risk mitigation measures pre-construction, and enable project teams to efficiently manage limited human and material resources.

    Intracranial aneurysms in polyarteritis nodosa (PAN) are exceedingly rare lesions with unpredictable behavior that pose real challenges to microsurgical and endovascular interventions owing to their inflammatory nature. We introduce a safe and effective alternative for treating these aneurysms using Pipeline embolization devices (PEDs). A 20-year-old man presented with diplopia, headaches, chronic abdominal pain, and weight loss. Diagnostic evaluations confirmed PAN, including bilateral giant cavernous carotid aneurysms. Cyclophosphamide and steroids achieved significant and sustained clinical improvement, with a decision to follow the aneurysms serially. Seven years later the left unruptured aneurysm enlarged, causing a sudden severe headache and a cavernous sinus syndrome. Treatment of the symptomatic aneurysm was pursued using flow diversion (PED) and the internal carotid artery was successfully reconstructed with a total of four overlapping PEDs. At 6 months follow-up, complete exclusion of the aneurysm was demonstrated, with symptomatic recovery. This is the first description of using a flow-diverting technique in an inflammatory vasculitis. In this case, PEDs not only attained a definitive closure of the aneurysm but also reconstructed the damaged and fragile arterial segment affected with vasculitis.

    The implementation of a Nuclear Power Plant (NPP) is a major undertaking for all entities involved, due to the necessity of planning work and coordination of the implementation process of the different fields of interest, starting with the governmental authorities and ending with the public. Having in view the specific investment costs (relatively high) for a NPP, finding an adequate financing structure is possible through an iterative process that involves first an assessment of the technical performances of the project and secondly, the mathematical modelling of the financing structure effects on the projects. In this respect, the paper will be focused on the main steps needed in order to promote an investment project in nuclear field, starting with the decision phase, providing the documentation requested by the local and international authorities to promote the project and ending with the negotiation of the contracts (commercial contract, financing contract, purchase contract, etc). The case study will be focused on the phases achieved in order to promote the Unit 2 NPP Cernavoda completion works project. (authors)

    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)

    Performance advantages of the new pilot project technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities. The decision to move forward with funding usually hinges on demonstrating actual cost reductions that can be credited to budgets and thereby truly reduce O&M or capital costs. Technology enhancements, while enhancing work methods and making work more efficient, often fail to eliminate workload such that it changes overall staffing and material cost requirements. It is critical to demonstrate cost reductions or impacts on non-cost performance objectives in order for the business case to justify investment by nuclear operators. The Business Case Methodology (BCM) was developed in September of 2015 to frame the benefit side of II&C technologies to address the “benefit” side of the analysis—as opposed to the cost side—and how the organization evaluates discretionary projects (net present value (NPV), accounting effects of taxes, discount rates, etc.). The cost and analysis side is not particularly difficult for the organization and can usually be determined with a fair amount of precision (not withstanding implementation project cost overruns). It is in determining the “benefits” side of the analysis that utilities have more difficulty in technology projects and that is the focus of this methodology. The methodology is presented in the context of the entire process, but the tool provided is limited to determining the organizational benefits only. This report describes a the use of the BCM in building a business case for mobile work packages, which includes computer-based procedures and other automated elements of a work package. Key to those impacts will be identifying where the savings are

    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)

    Strand, Monica; Hardeberg, Jon Y.; Nussbaum, Peter

    2005-01-01

    Recently the use of projection displays has increased dramatically in different applications such as digital cinema, home theatre, and business and educational presentations. Even if the color image quality of these devices has improved significantly over the years, it is still a common situation for users of projection displays that the projected colors differ significantly from the intended ones. This study presented in this paper attempts to analyze the color image quality of a large set of projection display devices, particularly investigating the variations in color reproduction. As a case study, a set of 14 projectors (LCD and DLP technology) at Gjovik University College have been tested under four different conditions: dark and light room, with and without using an ICC-profile. To find out more about the importance of the illumination conditions in a room, and the degree of improvement when using an ICC-profile, the results from the measurements was processed and analyzed. Eye-One Beamer from GretagMacbeth was used to make the profiles. The color image quality was evaluated both visually and by color difference calculations. The results from the analysis indicated large visual and colorimetric differences between the projectors. Our DLP projectors have generally smaller color gamut than LCD projectors. The color gamuts of older projectors are significantly smaller than that of newer ones. The amount of ambient light reaching the screen is of great importance for the visual impression. If too much reflections and other ambient light reaches the screen, the projected image gets pale and has low contrast. When using a profile, the differences in colors between the projectors gets smaller and the colors appears more correct. For one device, the average ΔE*ab color difference when compared to a relative white reference was reduced from 22 to 11, for another from 13 to 6. Blue colors have the largest variations among the projection displays and makes them

  14. World War II, The CANOL project and the Marwell Tar Pit: a case study

    Dobrowolsky, H.

    2000-01-01

    The CANOL project was a joint U.S.-Canada undertaking during World War II. It entailed the construction of a road and pipeline from the oil fields of Norman Wells on the Mackenzie River, 960 kms over the Mackenzie Mountains to a new refinery at Whitehorse. The goal was to provide a secure supply of aviation fuel far from the menace of Japanese bombers. Initially, the pipeline was expected to operate by October 1942. In actual fact, the first gasoline was not produced in the crude distillation unit until April 24, 1944, and it was not until November 1944 that the refinery finally began producing aviation fuel. Four months later, the pipeline and the refinery were shut down. The project cost American taxpayers $ 134 million. A total of 2650 kms of pipeline was laid. During the first nine months of pipeline operation 46,000 barrels of oil was spilled, much of it directly into the Mackenzie River. Total production from the refinery, which itself cost $ 27 million, wa 866,670 barrels of products. When the refinery was shut down, most of the refinery structures were dismantled and moved, via the Alaska Highway, to the newly discovered Leduc oilfields, but buildings, tanks and hydrocarbon waste were left behind. In a 1960 report it was estimated that some four million litres of oil has been pumped into a pit located within the containment berm formerly surrounding an 80,000 barrel oil storage tank which was dismantled after the shutdown. The bureaucratic dispute about who is responsible for cleaning up has been an issue ever since. The cost of cleanup was estimated at about $ 4 million in 1994. Since the federal government, the original owners of the land , transferred the land to provincial jurisdiction in 1970, it disclaimed any responsibility for site cleanup, however, there has been some recent evidence of willingness on the part of the Department of National Defence and the Department of Indian and Northern Affairs to determine proper actions to clean up the site

    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

    The Environmental Pre-Communication is a tool developed to identify the profiles of communities surrounding the marked area (lifestyle, resources, fragilities, beliefs, culture and wishes), how they make their living, and production (community dependence relationship with ecosystems, such as rivers and subsistence areas), social organization, needs and expectations. Besides developing a social economic diagnostic, pre-communication prepares a community perception study. Regarding gas pipelines, the area of study comprehends 200 m towards each side of gas pipeline right-of-way in rural areas and 400 m towards each side in urban areas. Pre-Communication diagnostic, which is included in the process of environmental licensing, is aimed at subsidizing EIS (Environmental Impact Statement), providing data which help to elaborate mitigating and compensatory plans and programs. Moreover, diagnostic information make it possible to run public forums before Public Hearings take place, aiming at clarifying specific community issues related to construction and reduction of resistances, avoiding problems and conflicts. Also, during the entrepreneurship implementation phase, there is the advantage to know the bordering community and its daily activities, increasing the effectiveness of Environmental Programs.

    2009-09-01

    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

  20. 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

  4. Pipeline Drag Reducers

    International Nuclear Information System (INIS)

    Marawan, H.

    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 %

  5. 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 Bolivia-Brazil Natural Gas Pipeline has 2.593 kilometers since Rio Grande City in Bolivia until Canoas City, in south Brazil. The pipeline crosses a lot of types of geological fields and difficult topography. The south spread of the gas pipeline is the most interesting because of its hard topography combined with the variety of geological materials, such as, colluvium deposits and debris flow areas. Curriola River is located at the kilometer 408, north part of Parana State. In this area, the pipeline crosses slopes of 45 degrees of inclination. The down part of Curriola's slope is composed by a non-resistance material (clay and little rock blocks) with a high porosity. Every year, during the rainy seasons, tension cracks are observed evidencing the earth movement. The slope stability is above the minimum expected for pipeline operation. The aim of this paper is to present the site characterization of the Curriola River Slope, together with all the investigation made in order to supply the studies with condensed information for the slope stabilization.

    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.

    The continuous underrepresentation of women in science, technology, engineering, and math (STEM), referred to as the leaky pipeline, has been examined from multiple perspectives internationally, while the attitudes and perceptions of preadolescent girls regarding STEM remain largely ignored. Employing a constructivist paradigm, this qualitative case study explored the perceptions and attitudes of 40 public elementary school female students across three grade levels regarding science, scientists, and career aspirations. Mixed-methods data collections included three survey instruments combined with semi-structured interviews. Self-efficacy, stereotype threat, and career choice theory provided the framework for the overarching research question: What are the attitudes and perceptions of female preadolescent students at the third, fourth, and fifth grade levels regarding science and scientists, and how might these dispositions affect their early development of STEM career aspirations and interests? The Three-Dimensions of Student Attitude Towards Science (TDSAS) instrument informed the exploration of self-efficacy; the modified Draw-A-Scientist Test (mDAST) and Rubric informed the exploration of stereotype threat; and the STEM-Career Interest Survey (CIS) informed the exploration of career aspirations. Semi-structured interviews were conducted with six participants. Results from this study indicated that the majority of the preadolescent girls thought science was an important topic to study and displayed an attitude of self-confident ability to learn science and be successful in science class. They highly enjoyed scientific experimentation and deeply valued problem solving. While they inferred they did not experience gender bias, the girls did engage in stereotyping scientists. Over half the girls expected to use science in their future careers, while a minority had already determined they wanted to be scientists when they grow up. The study concludes with

    Estimating a woman's risk of breast cancer is becoming increasingly important in clinical practice. Mammographic density, estimated as the percent of dense (PD) tissue area within the breast, has been shown to be a strong risk factor. Studies also support a relationship between mammographic texture and breast cancer risk. We have developed a fullyautomated software pipeline for computerized analysis of digital mammography parenchymal patterns by quantitatively measuring both breast density and texture properties. Our pipeline combines advanced computer algorithms of pattern recognition, computer vision, and machine learning and offers a standardized tool for breast cancer risk assessment studies. Different from many existing methods performing parenchymal texture analysis within specific breast subregions, our pipeline extracts texture descriptors for points on a spatial regular lattice and from a surrounding window of each lattice point, to characterize the local mammographic appearance throughout the whole breast. To demonstrate the utility of our pipeline, and optimize its parameters, we perform a case-control study by retrospectively analyzing a total of 472 digital mammography studies. Specifically, we investigate the window size, which is a lattice related parameter, and compare the performance of texture features to that of breast PD in classifying case-control status. Our results suggest that different window sizes may be optimal for raw (12.7mm2) versus vendor post-processed images (6.3mm2). We also show that the combination of PD and texture features outperforms PD alone. The improvement is significant (p=0.03) when raw images and window size of 12.7mm2 are used, having an ROC AUC of 0.66. The combination of PD and our texture features computed from post-processed images with a window size of 6.3 mm2 achieves an ROC AUC of 0.75.

    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.

    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.

    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

    With the continuous development of the electric power system and the pipeline networks used to convey oil or natural gas, cases of close proximity of high voltage structures and metallic pipelines become more and more frequent. Accordingly there is a growing concern about possible hazards resulting from voltages induced in the metallic pipelines by magnetic coupling with nearby power transmission lines. This paper presents a methodology for computation of the induced voltages in buried isolated metallic pipelines. A practical example of computation is also presented. (Author)

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

    The involvement of the Calgary-based company NOVA Gas International (NGI) in Malaysia`s peninsular gas utilization (PGU) project, was described. Phase I and II of the project involved linking onshore gas processing plants with a natural gas transmission system. Phase III of the PGU project was a gas transmission pipeline that began midway up the west coast of peninsular Malaysia to the Malaysia-Thailand border. The complex 549 km pipeline included route selection, survey and soil investigation, archaeological study, environmental impact assessment, land acquisition, meter-station construction, telecommunication systems and office buildings. NGI was the prime contractor on the project through a joint venture with OGP Technical Services, jointly owned by NGI and Petronas, the Thai state oil company. Much of NGI`s success was attributed to excellent interpersonal skills, particularly NGI`s ability to build confidence and credibility with its Thai partners.

    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

    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)

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

    The 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.

  19. LNG transport through pipelines

    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.)

    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.

    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

    A study was conducted on the lives of women and their families in Fort Nelson, British Columbia, and Whitehorse, Yukon Territory, two communities which are to be affected by the proposed construction of the Alaska Highway gas pipeline. The womens' socio-economic concerns resulting from the proposed construction were examined by means of interviews with samples of women living in the two communities. Results from the study include descriptions of the communities and their basic services, community planning and housing, women's work in the home and for wages, and the perceived impact of the pipeline on such matters as employment, social services, living costs, business, housing, crime, and the overall community. Recommendations are made to improve the planning process for the pipeline to include the taking into account of womens' needs in such areas as training, health care, housing, and community services. 213 refs., 4 figs., 2 tabs.

    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).

    Commonly, it is said that there is lack of communication among scientists, conservators, restorers, project managers and architects. But sometimes this communication flows, and we can find enormous benefits from and for all the participating agents. This is the case we present in this work, in which technical agents in charge of the restoration of a building, asked for some scientific advice to perform the restoration of a heritage building. The results were successful and fantastic for both of them, in terms of one part asking for consultation and the other answering to the demands and resolving real problems. This is the case of a marvellous Renaissance building (Medinaceli Dukes palace, 15th-16th centuries) in the central area of Spain (Cogolludo, Guadalajara). Focused on the restoration project, we were asked for consultancy on how to solve matters like the assessment of the already fixed in project cleaning method for the stone façades, the efficacy and durability methods for some conservation products to be applied, the presence or not of a patina on the stone; the viability of using some restoration mortars, and the origin of some efflorescences that came out just after placed in the building a restoration rendering mortar. Responses to these matters were answered by performing tests both in the lab and on site in the building. The efficiency and effects on stone of the blasting cleaning method was assessed by first analysing the nature and thickness of the surface deposits to be removed (SEM-EDS analyses); secondly, roughness and colour measurements were performed, and thirdly, SEM-EDS analyses were carried out again to determine whether the cleaning method was able to remove part of the surface deposits, completely, or even part of the stone substrate. Some conservation products were tested on stone specimens, both their efficacy and their durability, concluding that it was better not to apply any of them. A patina was found on the stone façade under SEM

    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

    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

    Spending for new or upgraded supervisory control and data acquisition (scada) systems and for additional remote-terminal units (RTUs) by North American pipelines and utilities will exceed $165 million through February 1996. New and updated scada systems will total 122 at a cost of more than $127 million; 143 RTU add-on projects will cost more than $38 million. Pipelines and combined utilities/pipelines will spend $89.5 million for 58 scada-system projects and $30.2 million for RTU add-on projects. Scada systems are computerized hardware and software systems that perform 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

    2005-01-01

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

    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.

  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.

    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 result of a survey which involves a 520km-long gas pipeline (Shebelinka-Dikanka-Kyiv) modification in the Ukraine is described, which will promote joint implementation programs under COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). Since the greenhouse effect of methane gas is 21 times as serious as that of CO2, it is important to ensure good maintenance and structural soundness for natural gas transporting pipeline systems. The currently available Ukrainian gas turbines and compressors are so obsolescent that their efficiency rate is as low as 23%. The rate will rise to 36% when the old ones are replaced by high power equipment capable of high efficiency combustion. Pipelines will be checked for deterioration due to stress corrosion cracking and dangerous pipes will be replaced, with attention paid particularly to joint sections. It is expected that there will be a greenhouse gas reduction of 512,000 tons (in terms of CO2) and a saving of 103,000 tons on fuel (in terms of crude). Balance is tentatively estimated in case the expected reduction in emissions is transacted in emission trading. Profitability will occur, in view of profit from emission trading and gas sales revenue after gas leakage prevention thanks to project implementation, when the emission right sells at 30 dollars/ton or higher. The rippling effect will be great now that the Ukrainian pipeline system is quite extensive (with 30% thereof superannuated). (NEDO)

    The need to keep pipelines operating safely and efficiently is paramount for any operator. Additionally, there is an increasing awareness at both regulatory and public level. Authorities around the world are adopting a more proactive approach as they seek to minimize the risk of human injuries or harm to the environment resulting from pipeline leaks. A joint industry project (JIP) led by DNV Energy is formulating guidelines for how to manage the integrity of submarine pipeline system. The resultant document of recommended practice, DNV RP-F116, will provide the oil and gas industry with a useful tool in an area where no such formal guidance currently exists. This paper gives an overview of the RP and demonstrates the use with a case study for the Siri field. The Siri field is operated by DONG Energy, Denmark and all infield pipelines were subjected to an integrity assessment using the Integrity Management process as outlined in the upcoming DNV RP-116. In parallel with establishing the RP, DNV has further developed the web-based software system, Orbit+, which is aligned with the RP. The software system is implemented and used by Dong Energy.

    Full Text Available Concrete structure is commonly used in the anchorages of a large cable-suspended pipeline crossing construction. With the increase of span and load, the stress on the concrete anchorages may rise rapidly. In case of traditional anchoring structure fixed by anchor rods, concrete cracking will occur, thereby reducing the anchorage life. To solve this problem, the pre-stressed structure was designed to effectively improve the efficiency of anchoring and reduce engineering cost. In the crossing construction of China–Myanmar Gas Pipeline, the pre-stressed technology was used to establish an effective pre-stressed anchoring system, which integrates the pre-stressed structures (e.g. tunnel anchorages in the anchors and the optimization measures (e.g. positioning mode, anchorage structure, concrete placement, pre-stressed, and medium injection, in line with the crossing structure and load features of this project. The system can delay the occurrence of concrete cracking and enhance the stress durability of the structure and anchoring efficiency. This technology has been successfully applied in the crossing construction of China–Myanmar Gas Pipeline, with good economic and social benefits, indicating that this technology is a new effective solution to the optimization of suspended pipeline anchorage structures, providing technical support for the development of pipeline crossing structure.

  10. Italmontaggi builds expertise Conquering monsoons, adverse conditions Bangladesh pipelines

    Energy Technology Data Exchange (ETDEWEB)

    1984-10-01

    Bangladesh natural gas pipeline projects have become a specialty for Italmontaggi Pte Ltd., Singapore-based gas pipeline contractor and engineering organization. The firm's latest project is a 35-mile, 24-in. gas pipeline, branching from the Bakhrabad-Chittagong main gas pipeline to the city gate station at Demra, near the capital city of Dacca. Gas is delivered to the Titas gas distribution system. The 35-mile turnkey project, valued at $25 million, included design, procurement, construction, and commissioning. A small pipeline was in existence from the Titas gas field to Dacca, but increased demand caused acute power shortages in the capital city's industrial areas. The new gas line will alleviate that problem. That project is a followup to Italmontaggi's successful completion of the major 108-mile, 24-in. main gas pipeline between the Bakhrabad gas fields, outside Dhaha, to the country's principal port and industrial center at Chittagong. Italmontaggi also installed 22 miles of ring main for the Chittagong gas distribution system. That included 12 miles of 24-in. and 10 miles of 16- and 20-in. to provide connections to industrial customers. Bangladesh lines difficult. The $45million contract for the Bakhrabad-toChittagong pipeline to Italmlontaggi, an autonomous offshoot of the Italian firm, resulted in a constant battle against hostile ground conditions, difficult access, and rapidly changing weather conditions. October-to- April is the dry season and Mayto-September is the wet season in this region. To keep the project moving, Italmontaggi developed two independent techniques for ground preparation during the wet season, and a pipelaying technique for the dry season. The new gas pipeline provides a major saving to the Bangladesh national economy as industries convert from oil to gas. Predicted savings are for more than $100 million in energy costs.

    In a continental dimensions country like Brazil, the pipeline modal faces the challenge of opening ROW's in the most different kind of soils with the most different geomorphology. To safely fulfill the pipeline construction demand, the ROW opening uses all techniques in earthworks and route definition and, where is necessary, no digging techniques like horizontal directional drilling, micro tunneling and also full size tunnels design for pipelines installation in high topography terrains to avoid geotechnical risks. PETROBRAS has already used the tunnel technique to cross higher terrains with great construction difficult, and mainly to make it pipeline maintenance and operation easier. For the GASBOL Project, in Aparados da Serra region and in GASYRG, in Bolivia, two tunnels were opened with approximately 700 meters and 2,000 meters each one. The GASBOL Project had the particularity of being a gallery with only one excavation face, finishing under the hill and from this point was drilled a vertical shaft was drilled until the top to install the pipeline section, while in GASYRG Project the tunnel had two excavation faces. Currently, two projects are under development with tunnels, one of then is the Caraguatatuba-Taubate gas pipeline (GASTAU), with a 5 km tunnel, with the same concepts of the GASBOL tunnel, with a gallery to be opened with the use of a TBM (Tunneling Boring Machine), and a shaft to the surface, and the gas pipeline Cabiunas-Reduc III (GASDUC III) project is under construction with a 3.7 km tunnel, like the GASYRG tunnel with two faces. This paper presents the main excavation tunneling methods, conventional and mechanized, presenting the most relevant characteristics from both and, in particular, the use of tunnels for pipelines installation.

    The Bolivia-Brazil Natural Gas Pipeline - GASBOL - begins in the city of Santa Cruz of La Sierra, in Bolivia, arriving in Canoas (RS), in Brazil, traveling an extension of 3.150 Km. Of this total, 2.593 Km are in Brazilian soil. In the kilometer 526+500m of the south spread, GASBOL crosses the reservoir of the Vocoroca's dam (COPEL), which had its operational level reduced, in face of the station of the droughts that usually reaches the area in the months of March to September. The lowing of the reservoir caused the turn of the course of Fojo River (Sao Joaozinho River) to its natural quota, forming a waterfall, whose hydraulic gradient caused the removal of the sediment and part of the foundation soil, discovering the pipe that was with space free from approximately 13 m of length. This paper discusses the solution adopted, as well as the several details of the recovery project, besides geotechnical and hydraulic studies and the aspects of safety of the Gas Pipeline. (author)

  18. Managing IT Projects in Public Companies: A Case Study

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available As part of its public sector modernization effort, a North African government has put a lot of effort and allocated significant budgets since 1997 to modernize one of its main public sector companies. Consequently, this company, that mainly offers postal services, initiated many IT-based projects to computerize all paper-based ongoing services offered through its branches and to present new products to customers. This company was aiming to improve service quality and to diversify the range of its services. However, some of these IT-based projects inevitably faced problems. Some projects were either not completed successfully, cancelled, over-budget or taking more time than scheduled. As a result, many employees and customers of this company were dissatisfied and complained about bad planning, slowness and significant disruptions in these projects, an event that affected adversely the quality of service. This study aims at determining the causes of these project disruptions, failures or delays. To achieve this aim, 30 experienced project developers and engineers working in that company’s IT department volunteered to respond to a detailed questionnaire specifically developed for this purpose. The questionnaire included questions about project vision clarity, time/cost management, project quality assurance, risk management and human resources management. Results show that the main reasons for disruptions, failure or delays in IT projects are lack of business plan and poor documentation during and after finishing projects, lack of clear quality assurance criteria, standards and reviews, and poor project risk management practices. Ramifications of such results in terms of improving IT project management practices in the public service sector are finally presented.

    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

    2017-07-01

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

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

  4. PLUGGING AND UNPLUGGING OF WASTE TRANSFER PIPELINES

    International Nuclear Information System (INIS)

    Ebadian, M.A.

    1999-01-01

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

    2010-01-01

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

  11. Permanent cathodic protection monitoring systems for offshore pipelines

    Energy Technology Data Exchange (ETDEWEB)

    Britton, Jim [Deepwater Corrosion Services Inc., Houston, TX (United States)

    2009-07-01

    Historically offshore pipeline cathodic protection monitoring has relied on the use of portable survey techniques. This has typically relied on ROV assisted or surface deployed survey methods. These methods have been shown to have technical as well as economic shortcomings, this is particularly true of buried offshore pipelines where accuracy is always questionable. As more focus is being placed on offshore pipeline integrity, it was time for a new method to emerge. The technology discussed involves the retro-placement of permanent clamp-on monitors onto the pipeline which can measure pipeline to seawater potential as well as current density. The sensors can be interrogated locally using light powered subsea voltage readouts. Application of the technology can be either during pipeline construction, during installation of life extension CP systems, or during routine subsea pipeline interventions. The new method eliminates the need for long cables or expensive acoustic or modulated data transfer and provides all the information required to fully verify CP system performance, thus eliminating the need for expensive close-interval surveys. Some deployment case histories will be presented along with feasibility of application on deep water pipelines and comparative economics. (author)

    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

    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

    1990-06-01

    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.

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

  5. 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.

    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.

    1992-01-01

    Since the mid 1980s, much of the marine science research effort in the United Kingdom has been focused into large scale collaborative projects involving public sector laboratories and university departments, termed Community Research Projects. Two of these, the Biogeochemical Ocean Flux Study (BOFS) and the North Sea Project incorporated large scale data collection to underpin multidisciplinary modeling efforts. The challenge of providing project data sets to support the science was met by a small team within the British Oceanographic Data Centre (BODC) operating as a topical data center. The role of the data center was to both work up the data from the ship's sensors and to combine these data with sample measurements into online databases. The working up of the data was achieved by a unique symbiosis between data center staff and project scientists. The project management, programming and data processing skills of the data center were combined with the oceanographic experience of the project communities to develop a system which has produced quality controlled, calibrated data sets from 49 research cruises in 3.5 years of operation. The data center resources required to achieve this were modest and far outweighed by the time liberated in the scientific community by the removal of the data processing burden. Two online project databases have been assembled containing a very high proportion of the data collected. As these are under the control of BODC their long term availability as part of the UK national data archive is assured. The success of the topical data center model for UK Community Research Project data management has been founded upon the strong working relationships forged between the data center and project scientists. These can only be established by frequent personal contact and hence the relatively small size of the UK has been a critical factor. However, projects covering a larger, even international scale could be successfully supported by a

    2009-02-01

    Full Text Available A major challenge in engineering education is retaining student interest in the engineering discipline. Active student involvement in engineering projects is one way of retaining student interest. Such involvement can only be realized if project inception comes entirely from the student. This paper presents a software game, RMU Monopoly, developed as a project requirement for a software engineering course and describes the challenges and gains of implementing such a project. The RMU Monopoly was proposed by three junior software engineering students. The game is a multi-platform software program that allows up to eight players and implements the rules of the Monopoly board game. To ensure agility the game was developed using the spiral software development model. The Software Requirements Specification (SRS document was finalized through an iterative procedure. Standard Unified Modeling Language (UML diagrams were used for product design. A Risk Mitigation, Monitoring, and Management Plan (RMMM was developed to ensure proactive risk management. Gantt chart, weekly progress meetings and weekly scrum meetings were used to track project progress. C# and Sub- Version were used in a client-server architecture to develop the software. The project was successful in retaining student interest in the software engineering discipline

    Project finance represents neither recent news nor a panacea in the fields of long term financing. It is not able to solve the chronicle scarcity of resources applied in big projects financing in developing countries. In fact, underdeveloped markets as the Brazilian one offer, at the beginning, almost no chances to the project finance solution. In this case a path full of barriers overcome the solutions that project finance may offer. The process to adapt this instrument to the Brazilian reality presents the following hindrances: a different law framework, capital market underdevelopment; economical instability; political and regulating risks; incapability of the national insurance companies to insure big projects; cultural differences and lack of know-how in this area, and lastly, the out of date tax system.

    2012-07-01

    The research project 'KLIMAT' was 1.1.2009 to 31.8.2012. The main goal of this project was to develop a 'best practice' methodology for quantifying the carbon footprint of products with a focus on fruits, vegetables, dairy and meat products. The methodology was tested on six selected case products. One of these products was the carrot. The product was selected because it is a product with high sales volume, a large part of the production takes place in Norway, and it may be assumed to represent the root vegetables which are a very important group of vegetable products. Oestfold Research, in conjunction with BAMA and Gartnerhallen, collected the necessary data to conduct the study. Data came from a group of 13 producers with ties to Laagendalen that all products supplied to the Laagen Gulrot for processing and packing. The producers were voluntarily affiliated with an online reporting system for a variety of information, including information about resource use that were used in this study. Climate track of carrot packed in the cup was, according to the methodology that was developed 0.39 kg Co2-ekv/kg product delivered to the consumer, 0.44 kg Co2-ekv/kg consumed carrot. (Author)

    The Research and Special Programs Administration administers the Natural Gas Pipeline Safety Act of 1968 (NGPSA) and the Hazardous Liquid Pipeline Safety Act of 1979 (HLPSA). The RSPA issues and enforces design, construction, operation and maintenance regulations for natural gas pipelines and hazardous liquid pipelines. This paper discusses a number of proposed and pending safety regulations and legislative initiatives currently being considered by the RSPA and the US Congress. Some new regulations have been enacted. The next few years will see a great deal of regulatory activity regarding natural gas and hazardous liquid pipelines, much of it resulting from legislative requirements. The office of Pipeline Safety is currently conducting a study to streamline its operations. This study is analyzing the office's business, social and technical operations with the goal of improving overall efficiency, effectiveness, productivity and job satisfaction to meet the challenges of the future

    1981-04-01

    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.

    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

    2008-11-01

    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

    1977-11-30

    In the controversy surrounding the proposal to grant Federal eminent domain to coal-slurry pipelines, the fundamental issue is whether, on balance, such a grant is in the national interest. The principal subissues (peripheral issues) of economics, water supply and disposal, energy consumption and conservation, employment, safety, and environmental impact are analyzed. It is found that, as compared with unit trains, which are the only immediate alternative for movement of large quantities of Western coal, the pipelines are not against the national interest, except in the case of employment. It is concluded that, on balance, the pipelines are in the national interest and should be granted the power of Federal eminent domain.

    1985-01-01

    Action for ad interim judicial relief in response to large projects approved of by the authorities very frequently take several years until a decision is taken by the court. Experience has shown that this applies in particular to large projects such as the construction of nuclear power plants, large-size industrial plants, or airports. It has become regular practice by the authorities concerned to issue an order for immediate execution upon the plan approving decision and granting of licence for said projects, in accordance with section 80, sub-section (2), no.4 of the VwGO. The problems thus created with regard to interim legal remedy sought by the parties concerned are of great significance. The book in hand discusses the question as to whether the practice of the administrative authorities and the courts satisfies the requirements embodied in the law, to provide for efficient legal protection.

    The Kepler mission is designed to continuously monitor up to 170,000 stars at a 30 minute cadence for 3.5 years searching for Earth-size planets. The data are processed at the Science Operations Center (SOC) at NASA Ames Research Center. Because of the large volume of data and the memory and CPU-intensive nature of the analysis, significant computing hardware is required. We have developed generic pipeline framework software that is used to distribute and synchronize the processing across a cluster of CPUs and to manage the resulting products. The framework is written in Java and is therefore platform-independent, and scales from a single, standalone workstation (for development and research on small data sets) to a full cluster of homogeneous or heterogeneous hardware with minimal configuration changes. A plug-in architecture provides customized control of the unit of work without the need to modify the framework itself. Distributed transaction services provide for atomic storage of pipeline products for a unit of work across a relational database and the custom Kepler DB. Generic parameter management and data accountability services are provided to record the parameter values, software versions, and other meta-data used for each pipeline execution. A graphical console allows for the configuration, execution, and monitoring of pipelines. An alert and metrics subsystem is used to monitor the health and performance of the pipeline. The framework was developed for the Kepler project based on Kepler requirements, but the framework itself is generic and could be used for a variety of applications where these features are needed.

    The importance of reducing energy consumption per tonne of output in the mining projects needs an innovative approach and style to change the behaviour and postures of the technical characteristics. The need for suitable energy policy can not be overlooked with the addition of new large size surface mining projects having a lot of technological development. But the immediate prescription to the problem is to pinpoint specific high energy consuming areas prefixed by thorough diagnosis and followed by deep scientific thought into it. To that extent this paper makes a primary attempt to characterise the various problems. (author). 7 tabs

    The ability to quickly find, easily use and effortlessly integrate data from a variety of sources is a grand challenge in Earth sciences, one around which entire research programs have been built. A myriad of approaches to tackling components of this challenge have been demonstrated, often with some success. Yet finding, assessing, accessing, using and integrating data remains a major challenge for many researchers. A technology that has shown promise in nearly every aspect of the challenge is semantics. Semantics has been shown to improve data discovery, facilitate assessment of a data set, and through adoption of the W3C's Linked Data Platform to have improved data integration and use at least for data amenable to that paradigm. Yet the creation of semantic resources has been slow. Why? Amongst a plethora of other reasons, it is because semantic expertise is rare in the Earth and Space sciences; the creation of semantic resources for even a single discipline is labor intensive and requires agreement within the discipline; best practices, methods and tools for supporting the creation and maintenance of the resources generated are in flux; and the human and financial capital needed are rarely available in the Earth sciences. However, other fields, such as biomedicine, have made considerable progress in these areas. The NSF-funded ClearEarth project is adapting the methods and tools from these communities for the Earth sciences in the expectation that doing so will enhance progress and the rate at which the needed semantic resources are created. We discuss progress and results to date, lessons learned from this adaptation process, and describe our upcoming efforts to extend this knowledge to the next generation of Earth and data scientists.

    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.

    Since September 2010, ArcelorMittal Monlevade has gained flexibility and an important opportunity to reduce the cost of its energy mix due to the arrival of the Natural Gas (NG) via Steel Valley Pipeline. The proposal of the project included the substitution of the Liquefied Petroleum Gas (LPG), Fuel Oil and Compressed Natural Gas for natural gas via pipeline. To support the investment decision, in addition to domestic economic and technical aspects, the macro economic environment concerning the NG was also taken into account. This paper shows the analysis for adjustment of internal equipment, the structure of the contract, the conceptual project of the gas distribution built inside the main events, the gains achieved, the alternatives for the acquisition of NG and operational flexibility of ArcelorMittal Monlevade in case of interruption of supply of natural gas.

    2001-01-01

    This paper summarizes the results of an experimental study on the onset of scour below and self-burial of pipelines in currents/waves. Pressure was measured on the surface of a slightly buried pipe at two points, one at the upstream side and the other at the downstream side of the pipe, both...... in the sand bed. The latter enabled the pressure gradient (which drives a seepage flow underneath the pipe) to be calculated. The results indicated that the excessive seepage flow and the resulting piping are the major factor to cause the onset of scour below the pipeline. The onset of scour occurred always...... locally (but not along the length of the pipeline as a two-dimensional process). The critical condition corresponding to the onset of scour was determined both in the case of currents and in the case of waves. Once the scour breaks out, it will propagate along the length of the pipeline, scour holes being...

  20. Facilitating major additions to gas pipeline capacity: innovative approaches to financing, contracting, and regulation

    International Nuclear Information System (INIS)

    Schlesinger, B.; George, R.

    1997-01-01

    The North American gas pipeline industry is in the process of changing from a highly regulated merchant business to a less-regulated, more competitive, transportation industry. This has changed the risk profiles of many companies. This study examined various innovative approaches to successfully financing major pipeline projects emphasizing pipeline capacity financing, contractual terms between shippers and pipelines, and regulatory developments. Besides suggesting options to enhance prospects for financing major pipeline expansion projects, the study also aimed at creating a better understanding of the regulatory market and commercial changes in the pipeline industry and their financing implications. The study also includes a review of the evolution in gas markets and a record of consultations with lenders, producers, marketers and users. Innovative financing, contracting and regulatory solutions are identified and assessed. 25 refs., 17 tabs., 16 figs

    International Nuclear Information System (INIS)

    Langan, P.T.

    1998-01-01

    A general project description and time schedule of the Maritimes and Northeast Pipeline project was presented. The pipeline project is a component of the Sable Offshore Energy Project which involves the development of six separate gas fields near Sable Island on the Scotian Shelf about 250 km off the south coast of Nova Scotia. The six fields under development represent about 3.5 trillion cubic feet of proven gas supply. Another 2 trillion cubic feet of gas has been discovered in nearby pools. There is an estimated additional 13 trillion cubic feet of potential gas reserve in the Scotian Shelf region. The 2 billion-dollar offshore project involves twenty-eight production wells, construction and installation of six platforms and a 225-km long two-phase pipeline from the central platform that will transport the product to shore. A gas plant will be constructed on-shore at Goldboro at which point the liquids will be stripped from the gas stream and transported by an onshore pipeline to Point Tupper, Cape Breton Island, to a fractionation facility for further market processing. The Maritimes and Northeast Pipeline will transport the gas product to markets in Nova Scotia, New Brunswick and New England. A number of unique challenges associated with the Maritimes and Northeast Pipeline project such as the problems of serving a new market, the highly competitive anchor market in the U.S., supply and operating characteristics, the regulatory process, and various competing projects were also reviewed. Sable offshore gas is scheduled to flow by late 1999

    The gas pipeline is used for the transport of natural gas at a great distance. Risks derived from the handling of a combustible material transported under high pressure, by pipelines that pass close to where people live, makes it necessary to adopt prevention, mitigation and control measures to reduce the effect in case of ignition of a gas leak. This work shows the development of a new mathematical model to determine areas of high consequence and their application, using widely available and...

  5. Pipeline oil fire detection with MODIS active fire products

    Science.gov (United States)

    Ogungbuyi, M. G.; Martinez, P.; Eckardt, F. D.

    2017-12-01

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

  7. Pipelines, utilities plan over 150 scada systems

    International Nuclear Information System (INIS)

    Anon.

    1992-01-01

    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

    In 2007, the Halifax Regional Municipality (HRM) approved the Alderney 5 energy project, an energy-efficiency retrofit of five municipal buildings on the Dartmouth, Nova Scotia, waterfront. The buildings concerned are: the Alderney landing complex, the Alderney gate office, the library, the Dartmouth ferry terminal and the old Dartmouth city hall building. The project has five major components: a mini-district-energy system of heating and cooling pipes that will connect all buildings to one central energy centre in Alderney gate; new gas conversion and high-efficiency boilers; new lighting; new seawater cooling; and an advanced coaxial energy storage system, saving $350,000 per year in energy costs. Construction, started in 2008, was funded through an innovative public private partnership between the Halifax Regional Municipality (HRM: $1 million), the federal government's technology early action measures program, and a company called High Performance Energy Systems.

  9. What, me worry? Pipeline certification at the FERC

    International Nuclear Information System (INIS)

    Schneider, J.D.

    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

    Gardiner, M. [GL Industrial Services, Loughborough (United Kingdom); Mendes, Renato F.; Donato, Guilherme V.P. [PETROBRAS S.A., Rio de Janeiro, RJ (Brazil)

    2009-07-01

    Quantitative Risk Assessment (QRA) of pipelines requires two main components to be provided. These are models of the consequences that follow from some loss of containment incident, and models for the likelihood of such incidents occurring. This paper describes how PETROBRAS have used Structural Reliability Analysis for the second of these, to provide pipeline- and location-specific predictions of failure frequency for a number of pipeline assets. This paper presents an approach to estimating failure rates for liquid and gas pipelines, using Structural Reliability Analysis (SRA) to analyze the credible basic mechanisms of failure such as corrosion and mechanical damage. SRA is a probabilistic limit state method: for a given failure mechanism it quantifies the uncertainty in parameters to mathematical models of the load-resistance state of a structure and then evaluates the probability of load exceeding resistance. SRA can be used to benefit the pipeline risk management process by optimizing in-line inspection schedules, and as part of the design process for new construction in pipeline rights of way that already contain multiple lines. A case study is presented to show how the SRA approach has recently been used on PETROBRAS pipelines and the benefits obtained from it. (author)

    Landslides have a serious impact on the integrity of oil and gas pipelines in the tough terrain of Western China. This paper introduces a solving method of axial stress, which uses numerical simulation and regression analysis for the pipelines subjected to landslides. Numerical simulation is performed to analyze the change regularity of pipe stresses for the five vulnerability assessment indexes, which are: the distance between pipeline and landslide tail; the thickness of landslide; the inclination angle of landslide; the pipeline length passing through landslide; and the buried depth of pipeline. A pipeline passing through a certain landslide in southwest China was selected as an example to verify the feasibility and effectiveness of this method. This method has practical applicability, but it would need large numbers of examples to better verify its reliability and should be modified accordingly. Also, it only considers the case where the direction of the pipeline is perpendicular to the primary slip direction of the landslide.

    This report is addressed to the Minister of Indian Affairs and to the Canadian North in Ottawa and deals with the social and economic impacts of a proposed gas pipeline in the South of Yukon and with the attitudes of the Yukonnese people with respect to this project. Many public hearings were held. The report discusses the Yukon people (Indians and non-Indians) and the consequences of the projected pipeline on the environment, the economics of the region and the way of life of its people. The report also presents the claims of the Indians pertaining to the land. It is advocated that an advance payment of $50M be made to the Indians and that the pipeline corporation pay a compensation of at least $200M to a fund administered by the Yukon. An organization for planning and regulating the pipeline should be establised. It is advised to delay constructing the pipeline until August 1981. Other recommendations are made. Many witnesses supported a layout following roughly the Tintina groove, but none supported the Dawson deviation. Most witnesses opposed constructing the lateral Dempster pipeline for the moment. The report is illustrated with numerous colour photographs. 7 figs., 2 tabs.

  15. 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.

This study is a retrospective analysis of process improvement projects in hospitals, facilitating a case-based reasoning approach to project definition. Data sources were project documentation and hospital-performance statistics of 271 Lean Six Sigma health care projects from 2002 to 2009 of general, teaching, and academic hospitals in the Netherlands and Belgium. Objectives and operational definitions of improvement projects in the sample, analyzed and structured in a uniform format and terminology. Extraction of reusable elements of earlier project definitions, presented in the form of 9 templates called generic project definitions. These templates function as exemplars for future process improvement projects, making the selection, definition, and operationalization of similar projects more efficient. Each template includes an explicated rationale, an operationalization in the form of metrics, and a prototypical example. Thus, a process of incremental and sustained learning based on case-based reasoning is facilitated. The quality of project definitions is a crucial success factor in pursuits to improve health care delivery. We offer 9 tried and tested improvement themes related to patient safety, patient satisfaction, and business-economic performance of hospitals.

    1997-01-01

    Hungary and Czechoslovakia in 1977 concluded a treaty for the building of dam structures in Slovakia and Hungary for the production of electric power, flood control and improvement of navigation on the Danube. In 1989 Hungary suspended and subsequently abandoned completion of the project alleging that it entailed grave risks to the Hungarian environment and the water supply of Budapest. Slovakia (successor to Czechoslovakia) denied these allegations and insisted that Hungary carry out its treaty obligations. It planned and subsequently put into operation an alternative project only on Slovak territory, whose operation had effects on Hungary's access to the water of the Danube. In this judgement, the Court found: (1) that Hungary was not entitled to suspend and subsequently abandon, in 1989, its part of the works in the dam project, as laid down in the treaty signed in 1977 by Hungary and Czechoslovakia and related instruments; (2) that Czechoslovakia was entitled ti start, in November 1991, preparation of an alternative provisional solution (called V ariant C ) , but not to put that solution into operation in October 1992 as a unilateral measure; (3) that Hungary's notification of termination of the 1977 Treaty and related instruments on 19 May 1992 did not legally terminate them (and they are consequently still in force and govern the relationship between the Parties); (4) and that Slovakia, as successor to Czechoslovakia became a party the Treaty of 1997.As to the future conduct of the Parties, the Court found: (1) that Hungary and Slovakia must negotiate in good faith in the light of the prevailing situation, and must take all necessary measures to ensure the achievement of the objectives of the 1997 Treaty; (2) that, unless the Parties agree otherwise, a joint operational regime for the dam on Slovak territory must be established in accordance with the Treaty of 1977; (3) that each Party must compensate the other Party for the damage caused by its conduct; (4

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

    Full Text Available Outsourcing IT functions is being developed as a replacement for implementing IT projects or rendering IT services within organizations. Organizations’ past experiences in outsourcing indicate that this process poses variety of risks and problems. This study is aimed to identify and prioritize the risks of outsourcing IT infrastructure projects. Classifying risks of outsourcing along with incorporating thematic experts’ experiences through the Delphi method, reveals various risks associated with the employer and the contractor as the primary sources of risks as well as general risks and chronological risks which occur in the periods before, during and after contracts. A total of 22 main risks were identified and categorized. Afterwards, based on the opinions obtained from thematic experts and using the Analytic Hierarchy Process, different types of risks were prioritized. The results suggest that those risks arising due to failings of structure and content are more important than those of technical and contextual knowledge.

    Full Text Available All construction professionals such as civil, mechanical, and electrical engineers, quantity surveyors, and architects have important roles in the construction process. Among these, architects are frequently appointed as a project manager (PM. The role of a PM will drive the success of the projects implementation. Therefore, the capability of an architect as a PM (ArPM is critical in reducing challenges encountered. Accordingly, the identification of these challenges is an important task in selecting an appropriate ArPM. The aim of this study is to identify the most critical challenges faced by an ArPM for construction projects. The data were collected through questionnaires and interviews with architects and professionals in the Malaysian construction industry. Because of the fuzziness and uncertainty of subjective responses, Fuzzy Set Ttheory is applied to identify critical challenges. A total of 65 questionnaires were distributed and 36 questionnaires were returned. The results revealed that the critical challenges faced by an ArPM are “poor planning,” “unfamiliar technology,” “unfamiliarity with green buildings and materials,” “inappropriate scheduling,” and “poor workmanship.” All critical challenges were then categorized into six main groups including technical, managerial, personal skills, contractual, psychological, and financial.

    Full Text Available Materials Requirements and Planning (MRP is a system of production planning and inventory control, which is used to manage manufacturing processes. Most MRP systems are software-based and are used to ensure that the materials are available for production, that the products are available for delivery to customers, that the lowest possible material and product level is maintained in store, as well as to plan delivery schedules and purchasing activities. Upon completion of scheduling, begins the process of follow-up, which includes the achievement of the project goals in terms of quantity, quality and costs in accordance with deadlines. MRP system was applied to project of 5000 housing units in Solug area, which is close to Benghazi city, Libya, with the aim to provide necessary cash flow to pay dues on time without delay to all involved project sub-contractors and material suppliers, to ensure the smooth flow of operations, as well as to diminish costs by reduction of temporary storages and rented areas. There is a correlation between time and cost of each activity. If the required time is shorter than the scheduled time of the certain activity, it would demand more resources, which further leads to the increase in direct costs of the given activity. Therefore, the output of MRP is important since commands are issued through planning in order to launch the suggested orders with the required quantities and within the limited time period.

    Natural energy problem, including the environmental aspects had changes into certain circumstances in recent years and natural gas has been a focus of constant attention from the viewpoint of energy efficiency and pollution free. From that kind of background, pipeline construction for petroleum and natural gas were considerate as energy infrastructure maintenance plan. Based on the clarification of Asian Pipeline Project (1997-2007) centered in Japan, international pipeline is needed as the natural gas is mainly transported from gas field in Russia and Middle East to consumer country such as Japan etc. It used in severe condition such as cold district and sea. In the meantime, pipeline steel is not just received damages by earth crust fluctuation and corrosion, but also suffered from the corrosion caused by anions that were dissolved in sea and groundwater. The diversification of dispersion and consumption structure of natural gas supply acceptance base are seen regarding, that made the needs of the storing are rising and dealt with the quantitative spatial expansion of the demand. By that, corrosion resistance, not only the hardness, tough, weldability, corrosiveness gas environment is extremely required. (author)

    2010-07-01

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

    This Elastic pipeline mathematic model is of crucial importance in natural gas pipeline simulation because of its compliance with the practical industrial cases. The numerical model of elastic pipeline will bring non-linear complexity to the discretized equations. Hence the Newton-Raphson method cannot achieve fast convergence in this kind of problems. Therefore A new Newton Based method with Powell-Wolfe Condition to simulate the Isothermal elastic pipeline flow is presented. The results obtained by the new method aregiven based on the defined boundary conditions. It is shown that the method converges in all cases and reduces significant computational cost.

    2012-03-01

    Full Text Available Objectives – Interviews with library staff and volunteers were conducted to evaluate the use of volunteers in UK public libraries via a case study of the Walter Gardiner Photographic Project, a digitisation project based in Worthing Library, to inform future guidelines on volunteer usage and to make recommendations to existing practice.Methods – Fourteen semi-structured interviews were carried out to explore the perceptions and experiences of both staff and volunteers of the project. All interviews were fully transcribed and then coded to identify emergent themes.Results – Key positives for volunteers were professional training, good time management and organization by staff, the friendliness and approachability of staff, and the informal nature of the volunteering. Enjoyment of the work and forming close relationships with others were key motivating factors. For staff, the completion of work which would have otherwise been impossible was the most positive outcome. Problem areas identified by volunteers were lack of contact time with project staff and feeling isolated from other library staff. For project staff, a lack of professionalism on behalf of some volunteers was the primary negative. Key issues to emerge were the need to strike a balance between formal and informal management, the need for good integration between the volunteers and host organization, and the importance of acknowledging the nature of the voluntary commitment.Conclusions – The project proved overall to be a successful example of using volunteers in public library projects with good examples of volunteer recruitment, training, and management being demonstrated. Areas of conflict that did arise stemmed from differing expectations of levels of service between staff and volunteers. Clarification on these expectations through a written volunteer agreement is advocated for further projects.

    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.

    1996-01-01

    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. Shingle Creek near the borders of Osceola and Orange Counties with 1,700 feet drilled. This paper reviews the design plans for construction and the emergency response plans should a rupture occur in the line

    1996-10-01

    By agreement between Latvijas gaze and DONG (the Danish State Gas Company) the Sloka branch on the main gas pipeline Riga-Liepaja was selected for inspection. This pipeline is 30.5 km long and was constructed in 1966/67. The objective of the project has been, based on detailed inspection of relative short lengths of pipe, to determine the integrity of the pipeline and to give advice concerning the continued use as a high pressure transmission pipeline. A further objective has been to provide Latvijas gaze with a package of modern cathodic protection measuring instruments and the necessary know-how for using the instruments. The objectives have been met as follows: Based on a document review together with measurements and observations in the field and in the laboratory, the condition of approximately 10 km of pipeline has been evaluated; Recommendations are given in this report with the aim of extending the life of the pipeline; A cathodic protection instrument package was delivered and a two week training course was arranged in Latvia for Latvijas gaze`s staff covering the use of the instruments.

  4. Strategizing Carbon-Neutral Mines: A Case for Pilot Projects

    Directory of Open Access Journals (Sweden)

    Ian M. Power

    2014-05-01

    Full Text Available Ultramafic and mafic mine tailings are a valuable feedstock for carbon mineralization that should be used to offset carbon emissions generated by the mining industry. Although passive carbonation is occurring at the abandoned Clinton Creek asbestos mine, and the active Diavik diamond and Mount Keith nickel mines, there remains untapped potential for sequestering CO2 within these mine wastes. There is the potential to accelerate carbonation to create economically viable, large-scale CO2 fixation technologies that can operate at near-surface temperature and atmospheric pressure. We review several relevant acceleration strategies including: bioleaching of magnesium silicates; increasing the supply of CO2 via heterotrophic oxidation of waste organics; and biologically induced carbonate precipitation, as well as enhancing passive carbonation through tailings management practices and use of CO2 point sources. Scenarios for pilot scale projects are proposed with the aim of moving towards carbon-neutral mines. A financial incentive is necessary to encourage the development of these strategies. We recommend the use of a dynamic real options pricing approach, instead of traditional discounted cash-flow approaches, because it reflects the inherent value in managerial flexibility to adapt and capitalize on favorable future opportunities in the highly volatile carbon market.

  5. Middle East gas export projects: The case of Abu Dhabi

    1995-01-01

    Abu Dhabi is ranked in the industry journals in the top 5 in the world tables of both oil and gas reserves. Gas is produced both Onshore and Offshore from associated and non-associated fields. Production has tripped during the last ten years and will increase further in the next few years as a result of current and planned investment. Development of Abu Dhabi's gas resources is aimed at enhancing oil production and recovery, meeting local and export demand and eliminating waste. Companies in Abu Dhabi are involved in all the main sectors of gas industry including production, processing, transportation and sales. The first large LNG export project by sea in Arabian Gulf was established in 1977 from Abu to Japan. Development continues and the gas is exported as LNG and is also processed into LPG and Pentane Plus for export. Japan remains the main market. The volume of Condensate available for export and processing will increase significantly in the next few years. In order to ensure a continuing and increasing supply of gas to world markets, in future years, prices will need to provide an adequate return on investment and should also reflect the environmental advantages of gas. 9 tabs

  9. Historical Paths and Intellectual Projects: The Case of Max Weber

    Directory of Open Access Journals (Sweden)

    Sven Eliaeson

    2017-06-01

    Full Text Available Max Weber is an elusive classic, and competing traditions claim his legacy. As in other cases, the interpretation of this classic should take into account formative experiences, historical context and links to older traditions. Weber theorized rational modernity, albeit with a certain ambiguity (the “iron cage”. He reworked the legacy of German historicism, but took it in the direction of methodological individualism; at the same time, and through the very affiliation to historicism, he contributed to German nation-building. His emphasis on the state as a necessary unit of analysis now seems obsolete, and so does his inclination to take the imperialistic dominance of the European great powers for granted. He was not immune to the ideology that opposed Germany’s cultural calling to Western civilization and Russian barbarism.

  10. Comprehensive long distance and real-time pipeline monitoring system based on fiber optic sensing

    Nikles, Marc; Ravet, Fabien; Briffod, Fabien [Omnisens S.A., Morges (Switzerland)

    2009-07-01

    An increasing number of pipelines are constructed in remote regions affected by harsh environmental conditions. These pipeline routes often cross mountain areas which are characterized by unstable grounds and where soil texture changes between winter and summer increase the probability of hazards. Due to the long distances to be monitored and the linear nature of pipelines, distributed fiber optic sensing techniques offer significant advantages and the capability to detect and localize pipeline disturbance with great precision. Furthermore pipeline owner/operators lay fiber optic cable parallel to transmission pipelines for telecommunication purposes and at minimum additional cost monitoring capabilities can be added to the communication system. The Brillouin-based Omnisens DITEST monitoring system has been used in several long distance pipeline projects. The technique is capable of measuring strain and temperature over 100's kilometers with meter spatial resolution. Dedicated fiber optic cables have been developed for continuous strain and temperature monitoring and their deployment along the pipeline has enabled permanent and continuous pipeline ground movement, intrusion and leak detection. This paper presents a description of the fiber optic Brillouin-based DITEST sensing technique, its measurement performance and limits, while addressing future perspectives for pipeline monitoring.

    2002-01-01

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

  17. Improved, Low-Stress Economical Submerged Pipeline

    Science.gov (United States)

    Jones, Jack A.; Chao, Yi

    2011-01-01

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

    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

    Full Text Available The effective estimation of costs is crucial to the success of construction projects. Cost estimates are used to evaluate, approve and/or fund projects. Organizations use some form of classification system to identify the various types of estimates that may be prepared during the lifecycle of a project. This research presents a parametric-cost model for pump station projects. Fourteen factors have been identified as important to the influence of the cost of pump station projects. A data set that consists of forty-four pump station projects (fifteen water and twenty-nine waste water are collected to build a Case-Based Reasoning (CBR library and to test its performance. The results obtained from the CBR tool are processed and adopted to improve the accuracy of the results. A numerical example is presented to demonstrate the development of the effectiveness of the tool.

  5. Simulation of high consequence areas for gas pipelines

    Directory of Open Access Journals (Sweden)

    Orlando Díaz-Parra

    2018-01-01

    Full Text Available The gas pipeline is used for the transport of natural gas at a great distance. Risks derived from the handling of a combustible material transported under high pressure, by pipelines that pass close to where people live, makes it necessary to adopt prevention, mitigation and control measures to reduce the effect in case of ignition of a gas leak. This work shows the development of a new mathematical model to determine areas of high consequence and their application, using widely available and easy to use software, such as Google Earth and Excel, to determine and visualize the area up to which the level of radiation can affect the integrity of people and buildings. The model takes into account the pressure drop into the gas pipeline from the compression station, the gas leakage rate and possible forms of gas ignition. This development is an alternative to the use of specialized software and highly trained personnel. The simulation is applied to a traced of the Miraflores-Tunja gas pipeline, using a macro developed in Excel to determine the impact area and compare it with the coordinates of the vulnerable areas. The zones where these areas intersect are constituted in high consequence areas and are identified along with the sections of the pipeline that affect them, to provide the operator with a risk analysis tool for the determination and visualization of the gas pipeline and its environment.

  7. Economic evaluation: wood stave pipelines

    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.

  8. Putting the coal slurry pipelines to the test

    Energy Technology Data Exchange (ETDEWEB)

    Sauermann, H B

    1978-03-01

    This paper deals with the advantages and disadvantages of coal slurry pipelines and describes coal slurry tests undertaken in three test circuits with 100, 200 and 250 mm diameter pipes. The test results from the test circuits were used to scale-up pressure gradients to larger pipe diameters. The construction and installation of hydraulic transport pipelines is simple and requires a minimum of space. The crossing of rivers, roads, railways or any other obstacles is comparatively easy. The operation, supervision and maintenance of a pipeline is simple since any pipeline can be easily adapted for fully automatic control. For this reason manpower requirements are small resulting in only small increases in operating costs during the life of a pipeline. This is an attractive feature in any economy troubled by inflationary trends. In transporting a commodity such as coal the quantities handled are usually large and the distances are long. The profitability of hydraulic transportation systems benefits from such operating conditions. Even though the various components of a slurry transport system, such as the slurrying facilities at the mine end and the dewatering facilities at the utilization end, are complex, their reliability is high. Against the advantages, the following limitations can be visualized: It is practically impossible to transport solids other than those for which the pipeline was designed; in this regard, road and rail transportation is more versatile. The solids throughput through a pipeline cannot be economically increased beyond its design throughput. Pipelining involves the use of fluids, in most cases water, which in some instances may not be readily available.

  12. Quality Management in Project Management Consulting. A Case Study in an International Consulting Company

    Directory of Open Access Journals (Sweden)

    Eduard-Gabriel Ceptureanu

    2017-02-01

    Full Text Available The present paper addresses quality management from the specific perspective of project management consulting service providers, in the framework of large infrastructure projects. Because of their supposed superiority in knowledge and experience, project management consultants have an ultimate responsibility for the proper implementing of the project. Therefore, quality management in consulting organizations should focus on critical success factors. As there is no consensus yet regarding the most important aspects of the consulting activity on which depend the achievement of the project aims, there is scope for further investigating this subject. Here, the case of a project management consulting organization involved in large infrastructure projects in Romania, Bulgaria, Moldova, Ukraine and Serbia is analyzed. Data collected through a questionnaire-based survey among international consultants and support personnel suggest that factors related to leadership style and communication skills are more closely tied to the success of the project than more technical aspects. The results constitute an empirical evidence of main success factors for specialized consulting services in project management and can be useful in improving business and project performance and achieving business excellence.

  13. 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...

  14. R&D Project Valuation Considering Changes of Economic Environment: A Case of a Pharmaceutical R&D Project

    Directory of Open Access Journals (Sweden)

    Jung Ho Park

    2018-03-01

    Full Text Available R&D project valuation is important for effective R&D portfolio management through decision making, related to the firm’s R&D productivity, sustainable management. In particular, scholars have emphasized the necessities of capturing option value in R&D and developed methods of real option valuation. However, despite suggesting various real option models, there are few studies on simultaneously employing mean-reverting stochastic process and Markov regime switching to describe the evolution of cash flow and to reflect time-varying parameters resulting from changes of economic environment. Therefore, we suggest a mean-reverting binomial lattice model under Markov regime switching and apply it to evaluate clinical development with project cases of the pharmaceutical industry. This study finds that decision making can be different according to the regime condition, thus the suggested model can capture risks caused by the uncertainty of the economic environment, represented by regime switching. Further, this study simulates the model according to rate parameter from 0.00 to 1.00 and risk-free interest rates for regimes 1 and 2 from ( r 1 = 4%, r 2 = 2% to ( r 1 = 7%, r 2 = 5%, and confirms the rigidity of the model. Therefore, in practice, the mean-reverting binomial lattice model under Markov regime switching proposed in this study for R&D project valuation contributes to assisting company R&D project managers make effective decision making considering current economic environment and future changes.

  15. Pipeline for Contraceptive Development

    Blithe, Diana L.

    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

  16. 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

  17. New heavy aggregate for offshore petroleum pipeline concrete coating Central West Sinai, Egypt

    Directory of Open Access Journals (Sweden)

    M.I. Abdou

    2014-12-01

    Full Text Available In this paper the local materials used in concrete mix are studied in a manner that they can resist the aggressive marine environment and mechanical damage, which can occur at several stages during transportation, construction and installation of the pipelines. In earlier studies we succeeded in finding the Egyptian ilmenite ore adequate for concrete weight coating and already utilized for many pipeline projects in Egypt. According to the presence of about 30% titanium oxides in ilmenite composition which may be extracted to be used in others strategically fields, the object of this paper is to study and evaluate the mechanical, chemical and physical properties of another local hematite high density iron ore to be used in subsea concrete weight coating for offshore petroleum pipelines. The results indicate that the local material of Um Bogma hematite iron ore can substitute both imported iron ore and local ilmenite from Abu Ghalaga in this field to reduce the cost effective and increased economical value of local ores. Laboratory and field tests were conducted for the hematite ore forming a concrete mix, composed of hematite ore, cement and fresh water according to international concrete coating specification requirements, the ore produces a concrete mix with 190–195 pcf minimum dry density and compressive strength, after 28 days of hydration, varying from 40 to 45 N/mm2 (400–450 kg/cm2 which comply with the international standards and specifications of submarine petroleum pipeline coating. In addition, local hematite shows superior results than local ilmenite and achieves 190 pcf instead of 180 pcf in case of using ilmenite.

  1. Selection of pipeline steels with an engineering fracture mechanical analysis

    Energy Technology Data Exchange (ETDEWEB)

    Stenbacka, N [Swedish State Power Board, Vaellingby

    1985-01-01

    Selection of pipeline steels is discussed on the basis of two mutually independent failure mechanisms: elastic fracture and plastic collapse. The presentation is restricted to axial flaws. A formal analysis shows that brittle fracture in modern pipelines has no high priority in design, since steels used today have a high fracture toughness. Instead, a case of practical concern is tha plastic collapse mode, where failure is flow stress controlled. Conditions governing this design case are specified. In conjunction with this, criterions for material selection with regard to fracture toughness is presented.

    In the area called Poligono Hidalgo, inside the Cerro Prieto IV zone in the Cerro Prieto geothermal field, BC, corrosion has occurred in the last few years on well casings and pipelines used for geothermal fluids. Corrosion test results are presented here for pipes, type API L-80 and ASTM A-53 grade B, which were subjected to condensate from wells 403 and 424. These wells have thrown corroded material from their respective casings. With these data we pinpoint corrosive conditions in this field area and determine which pipes are adequate to case wells in similar chemical, production conditions to minimize adverse effects and extend the life of the well, allowing more efficient exploitation of the deepest production zones in the reservoir. [Spanish] En el campo geotermico de Cerro Prieto, BC, dentro del area del Poligono Hidalgo en el sector conocido como Cerro Prieto IV, algunos pozos han presentado en los ultimos anos desgastes en sus tuberias de revestimiento y en las tuberias de linea para el transporte del fluido geotermico. Se presentan resultados de pruebas de corrosion con tuberias tipo API L-80 y ASTM A-53 grado B al ser sometidas al condensado de los pozos 403 y 424, los cuales han estado arrojando material de sus respectivas tuberias de revestimiento. Con estos datos se pretende conocer las condiciones corrosivas de esa zona del campo y determinar cual seria la tuberia ideal a utilizar en pozos con condiciones quimicas de produccion semejantes a fin de minimizar este efecto adverso y prolongar la vida de los pozos, a la vez que se permita la explotacion eficiente de las zonas productoras mas profundas del yacimiento.

  7. 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.

  10. The Pan-STARRS PS1 Image Processing Pipeline

    Science.gov (United States)

    Magnier, E.

    The Pan-STARRS PS1 Image Processing Pipeline (IPP) performs the image processing and data analysis tasks needed to enable the scientific use of the images obtained by the Pan-STARRS PS1 prototype telescope. The primary goals of the IPP are to process the science images from the Pan-STARRS telescopes and make the results available to other systems within Pan-STARRS. It also is responsible for combining all of the science images in a given filter into a single representation of the non-variable component of the night sky defined as the "Static Sky". To achieve these goals, the IPP also performs other analysis functions to generate the calibrations needed in the science image processing, and to occasionally use the derived data to generate improved astrometric and photometric reference catalogs. It also provides the infrastructure needed to store the incoming data and the resulting data products. The IPP inherits lessons learned, and in some cases code and prototype code, from several other astronomy image analysis systems, including Imcat (Kaiser), the Sloan Digital Sky Survey (REF), the Elixir system (Magnier & Cuillandre), and Vista (Tonry). Imcat and Vista have a large number of robust image processing functions. SDSS has demonstrated a working analysis pipeline and large-scale databasesystem for a dedicated project. The Elixir system has demonstrated an automatic image processing system and an object database system for operational usage. This talk will present an overview of the IPP architecture, functional flow, code development structure, and selected analysis algorithms. Also discussed is the HW highly parallel HW configuration necessary to support PS1 operational requirements. Finally, results are presented of the processing of images collected during PS1 early commissioning tasks utilizing the Pan-STARRS Test Camera #3.

  11. Effects of Business Model Development Projects on Organizational Culture: A Multiple Case Study of SMEs

    Directory of Open Access Journals (Sweden)

    Ulla Santti

    2017-08-01

    Full Text Available Previous research has shown that links between organizational culture and innovativeness/performance may act as a “social glue” that helps a company develop organizational culture as a competitive advantage. In this study of three case companies, the organizational culture change due business model development projects is studied using the Competing Values Framework (CVF tool and interviews with respondents about discovered changes. To reveal intervention and implied effects between business model development project and organizational culture changes, we used CIMO logic (context, intervention, mechanism, and outcome to bridge practice and theory by explanatory, backward-looking research. Our case studies of companies in relatively short-duration business model development projects indicate that organizational culture may have some dynamic characteristics, for example, an increase of the adhocracy organizational type in all case companies or an increase in the hierarchical leadership type in one case company. Thus, the development of an organizational culture type can be partly controlled. Our results also indicated business model development projects do have a minor effect on organizational culture, even when development activities have not been put fully into practice. However, the more comprehensively business model development project activities have been put into practice, the larger the effect on organizational culture.

    Software development projects face numerous challenges that threaten their successful completion. Whether it is not enough money, too little time, or a case of "requirements creep" that has turned into a full sprint, projects must meet these challenges or face possible disastrous consequences. A robust, yet flexible process model can provide a mechanism through which software development teams can meet these challenges head on and win. This article describes how the spiral model has been successfully tailored to a specific project and relates some notable results to date.

    1997-01-01

    Case study of the remediation of an oil seepage into a school building in a First Nations community, on the shores of the Albany River, in the James Bay region of northern Ontario, was discussed. The spill has created significant health hazards as manifested by nausea, vomiting and severe headaches among both students and teachers. Investigation determined that the O-ring fittings of the pipe joints, used during the installation of the oil pipeline linking the above-ground oil tank farm and the school building, were unsuitable for the intended use. They subsequently failed, allowing heating oil to leak from the pipes along the building and migrating into the gymnasium. A variety of remediation alternatives have been considered. The remedial actions taken include: in-situ containment using an impermeable membrane with passive venting and continuous air quality monitoring for the area below the recreation complex, excavation to create draining trenches, replacement of contaminated soil around the building and from the building to the river, and installation of a clay collar and oil/water separator in each drain line. The work was completed in January 1996. To date, all systems function satisfactorily

    Banks, W. F.

    1977-07-29

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

    The Bolivia-Brazil natural gas pipeline, which transports natural gas more than 3000 km from Bolivia to Brazil, cost US$2.1 billion to construct. Despite the substantial benefits for both Bolivia and Brazil and the involvement of reputable private partners, the perceived risks and complexities of this large project made financing it major challenge. neither of these countries has had a tradition of independent regulation or economic fuel pricing, and the pipeline was the first major gas infrastructure project involving the private sector in Brazil. The presentation explains the historical features of the project and how the project was used to open up Brazilian oil and gas sector to private investment and competition. (author)

    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.

  1. REMOTE DETECTION OF INTERNAL PIPELINE CORROSION USING FLUIDIZED SENSORS

    Energy Technology Data Exchange (ETDEWEB)

    Pipelines present a unique challenge to monitoring because of the great geographical distances they cover, their burial depth, their age, and the need to keep the product flowing without much interruption. Most other engineering structures that require monitoring do not pose such combined challenges. In this regard, a pipeline system can be considered analogous to the blood vessels in the human body. The human body has an extensive ''pipeline'' through which blood and other fluids are transported. The brain can generally sense damage to the system at any location and alert the body to provide temporary repair, unless the damage is severe. This is accomplished through a vast network of fixed and floating sensors combined with a vast and extremely complex communication/decision making system. The project described in this report mimics the distributed sensor system of our body, albeit in a much more rudimentary fashion. Internal corrosion is an important factor in pipeline integrity management. At present, the methods to assess internal corrosion in pipelines all have certain limitations. In-line inspection tools are costly and cannot be used in all pipelines. Because there is a significant time interval between inspections, any impact due to upsets in pipeline operations can be missed. Internal Corrosion Direct Assessment (ICDA) is a procedure that can be used to identify locations of possible internal corrosion. However, the uncertainties in the procedure require excavation and location of damage using more detailed inspection tools. Non-intrusive monitoring techniques can be used to monitor internal corrosion, but these tools also require pipeline excavation and are limited in the spatial extent of corrosion they can examine. Therefore, a floating sensor system that can deposit at locations of water accumulation and communicate the corrosion information to an external location is needed. To accomplish this, the project is divided into four main

  2. Simulating security of supply effects of the Nabucco and South Stream projects for the European natural gas market

    2010-12-15

    Due to the increasing European import dependency, significant additional natural gas volumes will be required. In addition to the Nord Stream pipeline, the Nabucco and South Stream pipeline are projects planned for the next decade to provide further gas supplies to the European market. As one of the European Union's energy policies' foci is security of supply, the question can be raised if and how these projects contribute to this objective not only in terms of diversification but also in case of supply disruptions such as occurred in 2009 during the Russia-Ukraine gas crisis. This paper discusses the impact of these two major gas import pipeline projects on the South-Eastern Europe gas supply and analyzes their effects on gas flows and marginal cost prices in general and in case of gas supply disruptions via Ukraine in a model-based analysis with the European natural gas infrastructure and dispatch model TIGER.

    2015-04-16

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

  5. The benefits of SCADA integrated pipeline leak detection

    2003-07-01

    Software based leak detection and locating for pipelines based upon evaluation of hydraulic parameters is a widely used approach to online pipeline integrity monitoring. Typically, these software packages are installed in a stand-alone configuration with a narrow bandwidth interface to the pipeline SCADA system. However, the performance characteristics of the SCADA system and interface do have a substantial impact on the performance of the leak detection system. By a tight integration of leak detection software into the SCADA system, a source of false alarms typically experienced with leak detection systems can be eliminated, the overall performance of the leak detection system can be improved, and the project costs can be reduced.

    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

    The damage caused by Third Party Interference (TPI) is one of the major causes of pipeline failures. Consequently, new technologies for identifying activities that may cause damage to our pipelines are constantly being developed. A recently completed project sponsored by a number of pipeline operators has investigated the use of high-resolution satellites for the integrity management of onshore transmission pipelines. The sponsors were BG Technology (on behalf of Transco), Dansk Olie NatureGas, Gasunie, BP, Gaz de France, Distrigas, and the Health and Safety Executive. The project started with a general review of the satellite technologies available and their potential. The study was then focussed on the identification of activities that might result in damage to the pipeline and the potential of high-resolution optical satellites in identifying hazardous activities. A key element of the study was a comparison with existing surveillance systems, which generally involve regular aerial patrols of the pipeline route. To achieve this a survey was carried out to try and evaluate the costs and benefits of existing systems. In addition a simple model for analysing the cost benefit of pipeline surveillance was constructed, and a functional specification for a surveillance system drafted. Finally the performance of the IKONOS 2 high-resolution satellite system was tested in a controlled experiment using targets placed along a pipeline route. The results of this test were compared with a similar test of helicopter-based surveillance carried out by one of the sponsors. (author)

  10. Energy intensity, life-cycle greenhouse gas emissions, and economic assessment of liquid biofuel pipelines.

    Strogen, Bret; Horvath, Arpad; Zilberman, David

    Petroleum fuels are predominantly transported domestically by pipelines, whereas biofuels are almost exclusively transported by rail, barge, and truck. As biofuel production increases, new pipelines may become economically attractive. Location-specific variables impacting pipeline viability include construction costs, availability and costs of alternative transportation modes, electricity prices and emissions (if priced), throughput, and subsurface temperature. When transporting alcohol or diesel-like fuels, pipelines have a lower direct energy intensity than rail, barge, and trucks if fluid velocity is under 1 m/s for 4-inch diameter pipelines and 2 m/s for 8-inch or larger pipelines. Across multiple hypothetical state-specific scenarios, profit-maximizing design velocities range from 1.2 to 1.9 m/s. In costs and GHG emissions, optimized pipelines outperform trucks in each state and rail and barge in most states, if projected throughput exceeds four billion liters/year. If emissions are priced, optimum design diameters typically increase to reduce pumping energy demands, increasing the cost-effectiveness of pipeline projects. Copyright © 2013 Elsevier Ltd.

  11. The Role of Public-Private Partnerships in Local Infrastructure: the Case of Carbon Offset Projects

    International Nuclear Information System (INIS)

    Teichmann, Dorothee

    2011-01-01

    Investment in low carbon infrastructure is considered as an important component of the fight against climate change. The mechanisms of climate regulation (such as carbon offsets) transfer to project developers the risks associated with reducing emissions of greenhouse gas (GHG) emissions, i.e. operational and technological risk, or risks associated with the environmental monitoring and the regulatory mechanism itself. The success of projects - and thus their ability to attract private capital - depends importantly on the risk sharing arrangements between the private and public partners involved in the project. We show that the delegation of tasks between the partners can create risks that affect the environmental effectiveness and economic efficiency of the project. Contracts need to be well designed to mitigate those risks. For a sample of landfill gas flaring projects financed under the Clean Development Mechanism, it is shown that the out-sourcing of the provision of technology creates additional risks. The out-sourcing of the development of the Project Design Documents as required by UNFCCC and the separation of the operation of the landfill and the CDM project appear to be manageable by risk sharing arrangements between partners. In the latter case, each partner should bear the risk associated with his own responsibility. In fact, if carbon revenues are the only income stream for the CDM project developer, the incentive to reduce GHG emissions is maintained. (author)

  12. Estimating the greenhouse gas benefits of forestry projects: A Costa Rican Case Study

    2000-09-01

    If the Clean Development Mechanism proposed under the Kyoto Protocol is to serve as an effective means for combating global climate change, it will depend upon reliable estimates of greenhouse gas benefits. This paper sketches the theoretical basis for estimating the greenhouse gas benefits of forestry projects and suggests lessons learned based on a case study of Costa Rica's Protected Areas Project, which is a 500,000 hectare effort to reduce deforestation and enhance reforestation. The Protected Areas Project in many senses advances the state of the art for Clean Development Mechanism-type forestry projects, as does the third-party verification work of SGS International Certification Services on the project. Nonetheless, sensitivity analysis shows that carbon benefit estimates for the project vary widely based on the imputed deforestation rate in the baseline scenario, e.g. the deforestation rate expected if the project were not implemented. This, along with a newly available national dataset that confirms other research showing a slower rate of deforestation in Costa Rica, suggests that the use of the 1979--1992 forest cover data originally as the basis for estimating carbon savings should be reconsidered. When the newly available data is substituted, carbon savings amount to 8.9 Mt (million tones) of carbon, down from the original estimate of 15.7 Mt. The primary general conclusion is that project developers should give more attention to the forecasting land use and land cover change scenarios underlying estimates of greenhouse gas benefits.

    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.)

    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

    From twenty years of information and communication technology (ICT) projects in the health sector, we have learned one thing: most projects remain projects. The problem of pilotism in e-health and telemedicine is a growing concern, both in medical literature and among policy makers, who now ask for large-scale implementation of ICT in routine health service delivery. In this article, we turn the question of failing projects upside down. Instead of investigating the obstacles to implementing ICT and realising permanent changes in health care routines, we ask what makes the temporary ICT project survive, despite an apparent lack of success. Our empirical material is based on Norwegian telemedicine. Through a case study, we take an in-depth look into the history of one particular telemedical initiative and highlight how ICT projects matter on a managerial level. Our analysis reveals how management tasks were delegated to the ICT project, which thus contributed to four processes of organisational control: allocating resources, generating and managing enthusiasm, system correction and aligning local practice and national policies. We argue that the innovation project in itself can be considered an innovation that has become normalised in health care, not in clinical, but in management work. In everyday management, the ICT project appears to be a convenient tool suited to ease the tensions between state regulatory practices and claims of professional autonomy that arise in the wake of new public management reforms. Separating project management and funding from routine practice handles the conceptualised heterogeneity between innovation and routine within contemporary health care delivery. Whilst this separation eases the execution of both normal routines and innovative projects, it also delays expected diffusion of technology. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The TRANSIERRA pipeline construction project, a 432 Km, 32'' pipeline located in the southern part of Bolivia was ready to kick off, waiting for an Administrative Concession that would allow the project to proceed. The implementation of the EHS Management Plan and the Social Strategies Plan was designed to get the Environmental Permits for changes generated with the detailed engineering design, Clear Cutting License, and a Negotiated agreements with representatives of the 8 Indigenous People's Territories and 6 Municipalities a long the ROW. Any delays due to our failure in achieving the necessary permits would have had an impact in fulfilling the already challenging one year schedule and stand by costs. TRANSIERRA designed a strategy to approach each of the EHS and S aspects in order to meet deadlines, yet implementing a solid EHS and S management system. The necessary resources were deployed to ensure compliance at all levels. The reforestation process required of 35 native species. There were neither seeds nor most of the plants available to complete this task. In addition no data was available on seed processing to successfully grow the number of required individuals; therefore TRANSIERRA developed and implemented a program to reach the reforestation objective.

    The purpose of this research was to study the recognition, application and quantification of the risks associated in managing projects. In this research, the management of risks in an oil and gas project is studied and implemented within a case company in Oman. In this study, at first, the qualitative data related to risks in the project were identified through field visits and extensive interviews. These data were then translated into numerical values based on the expert's opinion. Further, the numerical data were used as an input to Monte Carlo simulation. RiskyProject Professional™ software was used to simulate the system based on the identified risks. The simulation result predicted a delay of about 2 years as a worse case with no chance of meeting the project's on stream date. Also, it has predicted 8% chance of exceeding the total estimated budget. The result of numerical analysis from the proposed model is validated by comparing it with the result of qualitative analysis, which was obtained through discussion with various project managers of company.
