    Full Text Available The Nord Stream transboundary submarine pipeline, significant for its impact on the EU energy policy, has been a heav- ily debated issue in the Baltic Sea region during the past decade. This is partly due to the concerns over the effects that the pipeline might have on the Baltic Sea as a particularly sensitive large marine ecosystem.  This manuscript focuses on the issue from the viewpoint of the UNCLOS legal framework and its related treaties. It thus illustrates some of the more polemical topics arising in modern law of the sea and environmental law, eg limitations on the freedom to lay submarine pipelines, the scope and boundaries of marine scientific research, the obligation to consider alter- natives in the course of an EIA. In broader terms, this manuscript presents an explanatory study of matters mostly related to sustainable development, the precautionary principle and the ecosystem approach.

    2000-07-01

    This paper described the contracting challenges and bid evaluations for the GasPacifico Project which involved the construction of 543 km of NPS 20 and NPS 24 high pressure gas pipeline to connect natural gas reserves in the Province of Neuquen, Argentina to industrial and domestic markets in Concepcion, Chile. The line passes through difficult terrain in the Andes Mountain Range and Coastal Mountain Range. TransCanada International Ltd. (TCI) was responsible for the overall project management of the project from design, construction and contract administration. Call for bids on the project went out in March 1998 and contracts were awarded less than 5 months later in July 1998. TCI's objective was to ensure that the contractors had the experience, resources and financial ability to successfully complete the project. The work was divided into distinct contract packages on the basis of changes in pipe diameter, natural changes in topography, border between Argentina/Chile, and considerations related to the large number of landowners in agricultural and urban zones. Based on a review of pre-qualifications, 18 contractors were invited on a reconnaissance tour to familiarize the bidders with the project. When a review of the technical bids was completed, evaluation of the commercial bids began. When the difference in technical rating was very small, the lowest technically acceptable bidder was accepted. The project was constructed on schedule and under budget. It was noted that much of this success is a result of the contract selection process. 5 tabs., 3 figs.

    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

    An optimized gas pipeline design requires not only a qualified management of good engineering and planning, but also accurate estimates of capital investment and O and M. Compressor stations play a very important role on the success of a gas pipeline design and a careful selection of centrifugal compressors and drivers are key aspects for the success of the project. The state of the art design available nowadays for these kind of equipment provides overall high thermodynamic performance and consequently minimizes installed power requirements and energy usage with expressive savings on operating expenses along the economic life of the project. This paper will present a guideline for proper station design and selection of its turbo-compressors giving emphasis on the impact of fuel consumption on the economics of a gas pipeline project.

    The project management techniques used to manage the challenges of constructing the Gasoducto del Pacifico Pipeline from Argentina to Chile was discussed. The 543 km natural gas pipeline relied on experience of the GasAndes Pipeline Project to execute it in one year, from October 1998 to October 1999. The project management team met with success by using innovative techniques designed specifically to the following challenges: (1) fast track nature of the project, (2) contractual obligations imposed by the project management agreement between GasPacifico and TransCanada International which had the responsibility for the right-of-way acquisition, applying for regulatory approvals, design and construction of the project, (3) environmental constraints of a route through a national park in Chile and areas of high erosion and instability through the imposing Andes mountain range, (4) seasonal constraints, (5) two countries with two sets of laws and strict regulatory requirements, and (6) procurement and importation of major equipment, materials and pipe. The initial capacity of the pipeline without the addition of compression facilities was 3.7 million cubic metres per day. Total investment was in the order of $321 million US. It was emphasized that the risk associated with meeting the projects goals were minimized by critically evaluating all prospective bidders on the project. 1 ref., 7 figs.

    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.

    This paper is a walkthrough of the geohazard risk assessment performed for the Front End Engineering Design (FEED) of a planned large-diameter natural gas pipeline, extending from Eastern Europe to Western Asia for a total length of approximately 1,850 km. The geohazards discussed herein include liquefaction-induced pipe buoyancy, cyclic softening, lateral spreading, slope instability, groundwater rise-induced pipe buoyancy, and karst. The geohazard risk assessment lifecycle was comprised of 4 stages: initially a desktop study was carried out to describe the geologic setting along the alignment and to conduct a preliminary assessment of the geohazards. The development of a comprehensive Digital Terrain Model topography and aerial photography data were fundamental in this process. Subsequently, field geohazard mapping was conducted with the deployment of 8 teams of geoprofessionals, to investigate the proposed major reroutes and delve into areas of poor or questionable data. During the third stage, a geotechnical subsurface site investigation was then executed based on the results of the above study and mapping efforts in order to obtain sufficient data tailored for risk quantification. Lastly, all gathered and processed information was overlain into a Geographical Information database towards a final determination of the critical reaches of the pipeline alignment. Input from Subject Matter Experts (SME) in the fields of landslides, karst and fluvial geomorphology was incorporated during the second and fourth stages of the assessment. Their experience in that particular geographical region was key to making appropriate decisions based on engineering judgment. As the design evolved through the above stages, the pipeline corridor was narrowed from a 2-km wide corridor, to a 500-m corridor and finally to a fixed alignment. Where the geohazard risk was high, rerouting of the pipeline was generally selected as a mitigation measure. In some cases of high uncertainty in

    The Human Connectome Project (HCP) faces the challenging task of bringing multiple magnetic resonance imaging (MRI) modalities together in a common automated preprocessing framework across a large cohort of subjects. The MRI data acquired by the HCP differ in many ways from data acquired on conventional 3 Tesla scanners and often require newly developed preprocessing methods. We describe the minimal preprocessing pipelines for structural, functional, and diffusion MRI that were developed by the HCP to accomplish many low level tasks, including spatial artifact/distortion removal, surface generation, cross-modal registration, and alignment to standard space. These pipelines are specially designed to capitalize on the high quality data offered by the HCP. The final standard space makes use of a recently introduced CIFTI file format and the associated grayordinate spatial coordinate system. This allows for combined cortical surface and subcortical volume analyses while reducing the storage and processing requirements for high spatial and temporal resolution data. Here, we provide the minimum image acquisition requirements for the HCP minimal preprocessing pipelines and additional advice for investigators interested in replicating the HCP's acquisition protocols or using these pipelines. Finally, we discuss some potential future improvements to the pipelines.

    This paper described the work of welding process design for the "West-East" pipeline project, which is high pressure, large diameter and heavy wall thickness. According to the different geographical situation, climate, culture and the flexibility of the welding methods, this work recommended the semi-automatic process at the east and middle sections and automatic process at the west section of the pipeline project. The manual process is recommended on the tie-in joints and repairs. The double joint pipe and the 3 joint pipe are recommended at the water net place and some in-ditch welding place to reduce the welding volume. Also the special redesigned bevels are recommended for the automatic process and the semiautomatic process. Through all destructive tests, the results shows the welds are meet the requirements of related standards,specifications and design documents.

    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.

  13. Gas elephants: Arctic projects revived by expanding markets and pipelines

    2000-01-03

    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

    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

    This paper deals with the pipeline recently constructed by Bord Gais Eireann near the city of Cork in The Irish Republic. The 47.5 km pipeline comprises over 30 km of 9.5 mm and 17 km of 19.1 mm wall thickness for an outside diameter of 610 mm. This paper presents the global engineering approach adopted for the project and describes more in detail the specificities of the project and the challenges faced during production. One of the difficulties encountered was to manufacture a high strength pipeline of 19.1 mm wall thickness for HFW produced pipeline. The chemical composition of the 19.1 mm coil strip had also required new developments to accommodate the demanding drop weight tear test toughness requirement. Several methods were applied to mitigate potential risks such as increase of initial production test frequency, close monitoring during pipe production, identification of potential construction issues and the weldability performance were also tested.

    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.

    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: {yields} Auction design for gas pipeline transportation capacity. {yields} Empirical market-survey of Nabucco pipeline project auction as input data. {yields} Testing of three different allocation mechanisms: (i) NPV allocation; (ii) pro rata allocation; and (iii) optimization. {yields} Results show a trade-off between revenue optimization and fair allocation. {yields} Allocation per optimization is the favorable auction design when revenue maximization is more important than fair allocation. {yields} On the other hand, pro rata allocation is the auction design to be chosen when fairness of allocation is considered most central.

    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)

    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)

    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.

    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)

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

    This 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

    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

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

    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

    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)

    In 1998, the World Bank applied environmental and social standards in connection with dam and pipeline projects. Their position on international lending was consolidated by the strict application of safeguard policies. This paper focused on the use of safeguard policies in pipeline projects during the planning and implementation phases. The standards have been analyzed according to the role of safeguard policies in the examination for credit rating; the structure and nature of the safeguard policies; and, new trends in the application of standards. The example of the Baku-Tiblisi-Ceyhan oil pipeline was presented along with the requirements established under the World Bank Operational Directive (OP) 4.01 on environmental assessment. In 2003, the largest internationally active commercial banks voluntarily complied with the World Bank standards in major projects. The safeguard policies of the World Bank refer to standards which are the foundation for environmental and ecological risk assessment in the context of credit-rating reviews. Although the safeguard policies were modeled largely on the specifications of the United States Environmental Protection Act, they requires consideration of the national legislation of the host country, and ratified international environmental agreements. The following elements compose the development of a financing model for credit rating review: internal check of the pipeline project; discussion of the project outline with financing institutions; execution of feasibility studies; project-preparatory phase; and, conclusion of contracts. The safeguards include procedural and qualitative guidelines for environmental assessment, natural habitats, pest management, cultural property, indigenous people, involuntary resettlement, forestry, dam safety, international waterways, disputed areas, and information disclosure. 8 refs., 1 tab., 3 figs.

    Semi-parallel, or folded, VLSI architectures are used whenever hardware resources need to be saved at design time. Most recent applications that are based on Projective Geometry (PG) based balanced bipartite graph also fall in this category. In this paper, we provide a high-level, top-down design methodology to design optimal semi-parallel architectures for applications, whose Data Flow Graph (DFG) is based on PG bipartite graph. Such applications have been found e.g. in error-control coding and matrix computations. Unlike many other folding schemes, the topology of connections between physical elements does not change in this methodology. Another advantage is the ease of implementation. To lessen the throughput loss due to folding, we also incorporate a pipelining strategy in the design methodology. A complete decoder has been prototyped for proof of concept, and is publicly available. Another specific high-performance design of an LDPC decoder based on this methodology was worked out in past, and has been p...

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

    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.

    2005-07-01

    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.

    Ginorio, Angela B.; Huston, Michelle; Frevert, Katie; Seibel, Jane Bierman

    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.

    油田管道建设工程项目一般跨越空间范围较广,涉及的环境要素多,油品介质一旦发生泄漏其造成的环境污染后果是十分严重的,因此当前油田管道建设工程项目环境风险评价已成为国内外学术界所关注的一个热点。本文应用突变理论及突变级数评价法对自然环境因素、社会环境因素、交通环境因素三大要素进行分类,识别环境风险,确定风险等级,构建了管输建设环境风险评价驱动力因素指标体系以及管输建设环境风险评价突变模型。以陕北安塞——永坪管输工程项目为案例进行了实证研究,结合实测数据,得出影响管段风险重要度排序,指出其主要影响因素,提出相应的治理措施。%Oil pipeline construction projects across the spatial extent is wider than other generally. The environmental pollution will cause very serious consequences once the oil medium leaks out, so the current oil pipeline construction projects ERA has become a concern hot issue in international academic. In this paper the author classifies the three elements of the natural environment factors, social environ- mental factors, and traffic environment factors by the catastrophe theory and the catastrophe series evalua- tion in order to identify the environmental risk and determine the level of the risk and construct the driv- ing force factors index system of the pipeline construction ERA and the catastrophe model of the pipeline construction ERA. There is a case for empirical study though An' Sai -Yong Ping pipeline oil pipeline construction project. Finally, we can obtain the level sort that has affected the pipe risk by measured data to find the main factors, and then we can propose appropriate control measures.

    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 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.

    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{sub 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.

    1993-11-01

    This paper reviews a new four billion dollar arrangement which would start a major gas network between Brazil and Bolivia. The proposed 2,200 mile long, 28 and 14 inch pipeline network would connect Bolivian reserves with the undeserved markets of southern Brazil. The paper briefly reviews the economic involvement and impacts on both countries and the current market for natural gas in Brazil. Because most of Brazil's energy is currently from hydroelectric power or petroleum, the new distribution network will have dramatic effects on industries which need this high-grade fuel source for operation. Financing of this project will be by Petrobras and 49 percent through stock options.

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

    Directory of Open Access Journals (Sweden)

    Mona Luxion

    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.

    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.

    1997-12-31

    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.

    This paper describes the experience of PETROBRAS Transporte S.A. concerning the standardization process for its pipeline right-of-way (ROW) activities. This standardization initiative has been carried out within the Oil Pipelines and Terminals Standardization Program (PRONOT), focusing on planning, standardization and implementation of all norms and corporate procedures referring to TRANSPETRO's right-of-way activities. The process promoted the integration of isolated regional initiatives, a sense of unity and the creation of a learning network consisting of 60 employees. This paper presents the last phase's results concerning implementation of corporate standards, based upon achievements of previous phases. It covers the following topics: a general view of the whole process by way of introduction; the potential of integration of recent standardization results with TRANSPETRO's corporate management tools and information systems; definition of four performance indicators and their metrics related to pipeline right-of-way management, as well as a corporate standard for the requirements for contracting services related to rights-of-way inspection, maintenance and communication; challenges, barriers and benefits perceived by the team responsible for formulating and implementing standards and procedures in TRANSPETRO's Oil Pipelines and Terminals Unit.

    The ethics of using deception in research are discussed, and Aguinis and Handelsman's (1997) arguments that research using the bogus pipeline (BPL), in particular, is unethical are reviewed and critiqued. Stances that view any deception research as unethical may be reasonable, and lead to the conclusion that BPL research is unethical. However, if the position taken is that deception research may be ethically acceptable, then there is not basis for concluding that BPL research is intrinsically unethical. The same considerations that are taken into account when deciding whether any deception in research is ethical apply to decisions about the ethical appropriateness of using the BPL.

    The synergy of computational and physical network components leading to the Internet of Things, Data and Services has been made feasible by the use of Cyber Physical Systems (CPSs). 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.

    The aim of a series of sessions on Company Case Studies, is to learn from practical experiences, to give feed back to researchers on applicability of theories, methods and techniques, and last but not least, to market ergonomics. In order to learn from case material, reports need to be easy accessible and well structured. System ergonomics provides such a structure. Usually a project is not done twice, i.e. with and without ergonomics. Therefore, it is not possible to make comparisons and determine the impact of ergonomics directly. A different approach is needed. It has been suggested at the IEA2006 World Congress, to compile a database of published case studies, each case to be reported in a fixed report format and critically reviewed to enable generalizing the outcomes. This paper proposes such a format. At the IEA2012 World Congress 40 case studies have been accepted, representing applied ergonomics cases in manufacturing, process industries, aviation and logistic systems.

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

    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.

    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)

    2002-12-01

    On August 19, 2000 two seismometer networks in southeastern New Mexico recorded signals from a natural gas pipeline explosion. The explosion killed 12 members of an extended family that had been camping on the banks of a nearby river. Analysis of the particle motion, arrival times, and durations of the seismic signals indicate that three impulsive events occurred with origin times of 11:26:18.8 +/- 1.9, 11:26:43.6 +/- 2.1, and 11:27:01.7 +/- 2.0 (GMT). Each event generated an Rg wave with group velocity of 1.7-2.0 km/s and an air-coupled Rayleigh wave with a group velocity of about 345 m/s. The air-coupled Rayleigh waves had especially large amplitudes because of a geometric waveguide created by an atmospheric temperature inversion at the time of the accident. The first event was due to the explosive blowout of the buried, high-pressure pipeline while the second event was due to the ignition of the vented natural gas. The nature of the third event is unclear, however it was likely created by a secondary ignition. There were also two extended seismic events that were coeval with the first two impulsive events. The first resulted from the pre-ignition venting of the gas and lasted for about 24~s, while the second resulted from the post-ignition roaring of the flames and lasted for about one hour. Many of the source constraints provided by the seismic data were not available from any other investigative technique and so were valuable to a diverse range of parties including the New Mexico State Police, law firms involved in litigation related to the accident, the National Transportation and Safety Board, and the general public. Especially important was the seismically derived time between the blowout and ignition. The 24.0~s lag indicates that the initial rending of the pipe did not cause the ignition and that a more likely source was the nearby campsite, and it also significantly affected the amount of punitive damages the families of the victims were due since the

    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.

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

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

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

    Flow diverters are an exciting new class of endovascular devices that treat aneurysms by curative reconstruction of the parent artery. The Pipeline embolization device (PED) is the first FDA-approved intracranial flow diverting device available in the USA. This paper presents periprocedural results with the device in a series of 35 consecutive cases. All patients who underwent PED treatment of an intracranial aneurysm at our institution following FDA approval of the device in April 2011 were included in the series. Patient demographics, aneurysm characteristics, procedural details and technical and clinical outcomes were analyzed. Thirty-four patients (age range 23-78 years, mean 56.4 years) with 41 unruptured aneurysms (37 anterior circulation, four posterior circulation, mean size 11.4 mm, 20/21 large or giant) were treated with the PED in 35 cases (one patient had bilateral aneurysms treated on 2 separate occasions). Thirty-four of 35 cases (97%) were successfully completed. A total of 64 PEDs were implanted, with a mean number of 1.2 PEDs implanted per anterior circulation cases and 6.5 per posterior circulation cases. A single PED was implanted in 73% of cases. Immediate flow disruption occurred in 97% of the cases. The overall rate of major stroke or mortality was 3% (1/35 patients). Minor stroke, cranial nerve palsy, transient neurological deficit and groin complication occurred in one patient each (3% each, 12% total). Treatment of cerebral aneurysms with the PED carries an acceptable risk profile when a rigorous and uniform technique is used. Although the long-term results will need to be analyzed, the immediate procedural outcomes in the study series using this technique appear quite promising.

    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.

    Long-distance pipeline construction results in marked human disturbance of the regional ecosystem and brings into question the safety of pipeline construction with respect to the environment. Thus, the direct environmental impact and proper handling of such large projects have received much attention. The potential environmental effects, however, have not been fully addressed, particularly for large linear pipeline projects, and the threshold of such effects is unclear. In this study, two typical eco-fragile areas in western China, where large linear construction projects have been conducted, were chosen as the case study areas. Soil quality indices (SQI) and vegetation indices (VI), representing the most important potential effects, were used to analyze the scope of the effect of large pipeline construction on the surrounding environment. These two indices in different buffer zones along the pipeline were compared against the background values. The analysis resulted in three main findings. First, pipeline construction continues to influence the nearby eco-environment even after a 4-year recovery period. During this period, the effect on vegetation due to pipeline construction reaches 300 m beyond the working area, and is much larger in distance than the effect on soil, which is mainly confined to within 30 m either side of the pipeline, indicating that vegetation is more sensitive than soil to this type of human disturbance. However, the effect may not reach beyond 500 m from the pipeline. Second, the scope of the effect in terms of distance on vegetation may also be determined by the frequency of disturbance and the intensity of the pipeline construction. The greater the number of pipelines in an area, the higher the construction intensity and the more frequent the disturbance. Frequent disturbance may expand the effect on vegetation on both sides of the pipeline, but not on soil quality. Third, the construction may eliminate the stable, resident plant

    Within the scope of a DVGW research project the KIWA, SKZ and MPA Darmstadt research institutes examined the condition and possible residual service life of gas and water pipelines of the first PE generation operating for more than 30 years. The creep rupture curves determined on the old pipelines are very similar to the ones ascertained approx. 40 years ago, allowing an extrapolation over at least another 25 years at service temperature upon expiry of the originally predicted service life of 50 years. Both the gas and water pipelines still show an actively effective thermal stabilization so that an early thermo-oxidative failure is not to be expected even after expiry of the originally estimated service life of 50 years. Nevertheless, public utilities operating gas and water pipelines made of PE of the first generation are recommended to closely observe the damage statistics/damage progression within the scope of the regular inspections of the pipeline network, thus being in a position to recognise ageing phenomena which indicate an end of the service life of the pipeline system in time and perform further examinations.

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

    Full Text Available This study aims are data acquisition, control and online modeling of an oil collection pipeline network using a SCADA «Supervisory Control and Data Acquisition» system, allowing the optimization of this network in real time by creating more exact models of onsite facilities. Indeed, fast development of computing systems makes obsolete usage of old systems for which maintenance became more and more expensive and their performances don’t comply any more with modern company operations. SCADA system is a telemetry and control system adapted for particular requirements of an oilfield management. Thanks to its different functions, we take advantage of this system to solve production problems especially those related to oil collecting pipeline network. In fact this network is confronted to some problems, in particular pressure losses which has significant effect on the production. This problem can be taken under control by the awareness of pipeline network operation and all its process data (especially junctions in real time. This will allow online creation of representative and accurate computerized models for the oil collecting pipeline network including producing wells, collecting pipelines, manifolds and others facilities.

    One of the aspects what more characterize the gas natural is the possibility of your state physical can be adapted the conditions of transport , since the zone where is producing until the region where it is consumer (distant only one from another), you can stand out this three principal alternatives: gas pipelines; in the form of liquefied, in cryogenic ships; in the form of derive compounds that can be liquids or solid. For susceptibilities to the corrosion of the carbons steels used in the equipment and natural gas pipelines of the production reservoirs until the denominated city gates, it makes be necessary to identify the acting corrosive agents and monitoring them along time, because, the failures for internal corrosion in natural gas pipelines can carry serious environmental problems, damages to the image of the distributors companies and prejudices related to operational continuity. Some aspects of the processing of the natural gas are argued, as well as your effect regarding the internal corrosion in natural gas pipelines. To leave of this analysis, it tries establishing a monitoring and controlling methodology of the internal corrosion in field for natural gas pipelines. For chemical characterization of the samples of the black powder were used analyses for Scanning Electron Microscopy, X-Ray Diffraction, X-Ray Fluorescence. (author)

    Accurate inspection techniques are needed to ensure the integrity of pipelines. This working group discussed methods of reducing pipeline failures for a variety of pipes. A summary of recent pipeline performance statistics was presented, as well as details of third party damage and fiberglass pipe failures. A batch inhibitor joint industry project was described. The session demonstrated that integrity program need to be developed at the field-level as well as at the upper management level. Fiberglass pipeline failures are significant problem for pipeline operators. Corrosion monitoring, pigging and specific budgets are needed in order to ensure the successful management of pipeline integrity. New software developed to predict pipeline corrosion rates was discussed, and methods of determining mole fractions and flow regimes were presented. The sessions included updates from regulators and standards agencies as well as discussions of best practices, regulations, codes and standards related to pipeline integrity. The working group was divided into 4 sessions: (1) updates since 2007 with input from the Canadian Association of Petroleum Producers (CAPP) and the Upstream Pipeline Integrity Management Association (UPIMA); (2) integrity of non-metallic pipelines; (3) upstream pipeline integrity issues; and (4) hot topics. tabs., figs.

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

    Toscana virus (TOSV) represents a frequent cause of viral meningitis in the Mediterranean Basin that remains neglected in neighbouring countries. We report a documented TOSV meningitis case in a traveller returning from Tuscany to Switzerland. While routine serological and PCR assays could not discriminate between TOSV and Sandfly fever Naples virus infection, a high-throughput sequencing performed directly on the cerebrospinal fluid specimen and analysed with the ezVIR pipeline provided an unequivocal viral diagnostic. TOSV could be unequivocally considered as the aetiological agent, proving the potential of ezVIR to improve standard diagnostics in cases of infection with uncommon or emerging viruses.

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

    Full Text Available Abstract Background 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. Results 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. Conclusions 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.

    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.

  12. Vortex induced vibrations of free span pipelines

    Energy Technology Data Exchange (ETDEWEB)

    Koushan, Kamran

    2009-07-01

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

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.

    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.

    The Cartier Pipeline is a proposed stand-alone pipeline involving equal partnership between Alberta's Enbridge Consumers Gas and Quebec's Gaz Metropolitain to bring offshore Atlantic gas to markets in eastern Canada and the New England states. The inservice date for the proposed pipeline is November 2004. The $270 million dollar project will require 262 km of pipeline in Quebec with an annual transportation capacity of 67 Bcf initially with a cost effective expandability to 125 Bcf. Contracted commitments so far include 30 Bcf/year from Gaz Metropolitain and the same from Enbridge. Cartier offers attractive, base load, long term, complementary market diversification for Atlantic production. It also provides producers with a competitive channel to Ontario storage. In addition, the pipeline will contribute to lower tolls in Canada and the overall path to Dracut (Boston). Several graphs depicting expected costs of delivered gas supplies to Montreal were also included with this power point presentation. tabs., figs.

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

    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.

    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.

    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.

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

    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. PMID:28316868

    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.

    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.

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

    Pipelines are the most modern, effective and safest transport system, which is world widely spread in a network of millions km length and is annually enlarged about thousands of km. It is sure that these systems, if they should stay save and effective, must be maintained adequately. A technique, which provides accurate and reliable measurement data without interrupting the pipeline operation, ''through the wall'', is the ultrasonic technology. This non-intrusive technology provides data for pig detection as well as it is used for recognising products in pipelines, detecting levels or full/empty states and accomplishment of sediment measurement, distance measurements, position detections and leak search. The article gives a review and describes some applications of ultrasonic technology in pipeline technique. (orig.)

    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.

  1. Astronomical pipeline processing using fuzzy logic

    Science.gov (United States)

    Shamir, Lior

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

    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.

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

    The paper studies on case-based reasoning of uncertain product attributes in configuration design of a product family. Interval numbers characterize uncertain product attributes. By interpolating a number of certain values randomly to replace interval numbers and making projection pursuit analysis on source cases and target cases of expanded numbers, we can get a projection value in the optimal projection direction. Based on projection value, we can construct a case retrieval model of projection pursuit that can handle coexisting certain and uncertain product attributes. The application examples of chainsaw configuration design show that case retrieval is highly sensitive to reliable results.

    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.

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

    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)

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

    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

    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.

    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.

    Heacock, Lucy Vogel

    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.

    The Cementitious Barriers Partnership Project (CBP) is a multi-disciplinary, multi-institution cross cutting collaborative effort supported by the US Department of Energy (DOE) to develop a reasonable and credible set of tools to improve understanding and prediction of the structural, hydraulic and chemical performance of cementitious barriers used in nuclear applications. The period of performance is >100 years for operating facilities and > 1000 years for waste management. The CBP has defined a set of reference cases to provide the following functions: (i) a common set of system configurations to illustrate the methods and tools developed by the CBP, (ii) a common basis for evaluating methodology for uncertainty characterization, (iii) a common set of cases to develop a complete set of parameter and changes in parameters as a function of time and changing conditions, (iv) a basis for experiments and model validation, and (v) a basis for improving conceptual models and reducing model uncertainties. These reference cases include the following two reference disposal units and a reference storage unit: (i) a cementitious low activity waste form in a reinforced concrete disposal vault, (ii) a concrete vault containing a steel high-level waste tank filled with grout (closed high-level waste tank), and (iii) a spent nuclear fuel basin during operation. Each case provides a different set of desired performance characteristics and interfaces between materials and with the environment. Examples of concretes, grout fills and a cementitious waste form are identified for the relevant reference case configurations.

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

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

    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)

    The world first successful SmartPlug operation took place at the Dimlington process plant in UK in 1999. Since 1999, the SmartPlug system has been deployed on more than 80 projects worldwide allowing the operators to perform pipeline repair work, modifications, or tie-ins with the pipeline systems full of product, and at full production pressure. Mid-line applications of the SmartPlug system allows the operator to tie a new pipeline into an existing pipeline without displacing the oil or gas and eliminates time needed to flare, depressurize, empty the line and commission the line before start up. The first SmartPlug installations were done to isolate pig trap valves or ESD valve from the pipeline allowing the valve to be replaced at full pipeline pressure, and in some instances while production was flowing. Some pipelines have multiple platforms or fields tied in along the pipeline, and the SmartPlug system is frequently used to isolate a single platform to allow platform removal or riser repair without impacting the production flow in the remaining part of the pipeline system.

    In India, the likelihood of a girl student opting out of a physics course only because of gender issues is remote. Even though no special care is taken to attract women, a large percentage of the top-ranking students opt to major in physics. However, subtle forces operate in higher academia. The number of women in teaching and research institutes continues to be dismally low. The confidence and motivation of women students shows a distinct attenuation at the tertiary level. Inasmuch as the undergraduate years lay the foundation for a career in physics, there is a critical need to create learning experiences for women students that would enhance their motivation, nurture talent, and generate confidence in their capacity to make a creative contribution. The author has spent several years teaching at a women's college and in a university department with few women on the faculty. She has coordinated the Learning Through Investigative Projects program for undergraduate students of both genders. In a dual-pronged strategy, students are constructively engaged in open-ended investigative projects and assigned specific tasks. The touchstone of this program is the ambience in which the projects are carried out and the cognitive changes it effects in students as they are weaned away from the prevalent transmissionist mode of teaching and led to a constructivist paradigm of learning. They acquire an ability to work independently. The program and the underpinning pedagogic model have been very successful in capacity building and have influenced many students to choose careers in physics and academia. I present a case study of the work carried out under Project Science Online, in which students helped develop a microcomputer-based laboratory.

    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.

    The Bonneville Power Administration is proposing to fund a fish passage enhancement project on Twelvemile Creek in Lemhi County, Idaho with the Lemhi Soil and Water Conservation District. The goal of this project is to enhance fish passage in Twelvemile Creek by eliminating barriers and increasing flows. The project goals will be accomplished by eliminating two diversions and two pumps from Twelvemile Creek by consolidating the flow into one diversion, eliminating ditch loss with pipe, and switching one irrigator from flood to sprinkler irrigation. This project will also attach the irrigators to a fish screen that will be installed by the Idaho Department of Fish and Game.

    In response to the interest in ensuring the continued safe operation of vintage pipelines and the integrity management challenges related to those pipelines, PRCI sponsored in 2009 a project called {sup V}intage Girth Weld Defect Assessment - Comprehensive Study{sup .} Its objectives focused on girth welds made with the shielded metal arc welding (SMAW) process, particularly with regard to: review of approaches for evaluating the integrity of these welds; description of the typical characteristics and properties of SMAW vintage welds; determination of gaps in available information and technology that hinder effective integrity assessment and management of vintage girth welds. A very extensive literature review was performed as part of this project. Key findings include the following. The failure rate of early generation girth welds is low, especially when considering the rate of catastrophic failures. Pipeline girth welds are unlikely to fail unless subjected to axial strains that far exceed the strains related to internal pressure alone.

    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.

    Gillette, J .L.; Kolpa, R. L

    2008-02-01

    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

    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).

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

    The 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.

  17. Application of pre-stressed technology in the crossing construction of the China–Myanmar Gas Pipeline

    Directory of Open Access Journals (Sweden)

    2015-01-01

    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.

    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.

    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.

    In bioinformatics, it is important to build extensible and low-maintenance systems that are able to deal with the new tools and data formats that are constantly being developed. The traditional and simplest implementation of pipelines involves hardcoding the execution steps into programs or scripts. This approach can lead to problems when a pipeline is expanding because the incorporation of new tools is often error prone and time consuming. Current approaches to pipeline development such as workflow management systems focus on analysis tasks that are systematically repeated without significant changes in their course of execution, such as genome annotation. However, more dynamism on the pipeline composition is necessary when each execution requires a different combination of steps. We propose a graph-based approach to implement extensible and low-maintenance pipelines that is suitable for pipeline applications with multiple functionalities that require different combinations of steps in each execution. Here pipelines are composed automatically by compiling a specialised set of tools on demand, depending on the functionality required, instead of specifying every sequence of tools in advance. We represent the connectivity of pipeline components with a directed graph in which components are the graph edges, their inputs and outputs are the graph nodes, and the paths through the graph are pipelines. To that end, we developed special data structures and a pipeline system algorithm. We demonstrate the applicability of our approach by implementing a format conversion pipeline for the fields of population genetics and genetic epidemiology, but our approach is also helpful in other fields where the use of multiple software is necessary to perform comprehensive analyses, such as gene expression and proteomics analyses. The project code, documentation and the Java executables are available under an open source license at http://code.google.com/p/dynamic-pipeline. The system

    2006-05-04

    Internal inspection of pipelines is an important tool for ensuring safe and reliable delivery of fossil energy products. Current inspection systems that are propelled through the pipeline by the product flow cannot be used to inspect all pipelines because of the various physical barriers they encounter. Recent development efforts include a new generation of powered inspection platforms that crawl slowly inside a pipeline and are able to maneuver past the physical barriers that can limit inspection. At Battelle, innovative electromagnetic sensors are being designed and tested for these new pipeline crawlers. The various sensor types can be used to assess a wide range of pipeline anomalies including corrosion, mechanical damage, and cracks. Battelle is in the final year on a projected three-year development effort. In the first year, two innovative electromagnetic inspection technologies were designed and tested. Both were based on moving high-strength permanent magnets to generate inspection energy. One system involved translating permanent magnets towards the pipe. A pulse of electric current would be induced in the pipe to oppose the magnetization according to Lenz's Law. The decay of this pulse would indicate the presence of defects in the pipe wall. This inspection method is similar to pulsed eddy current inspection methods, with the fundamental difference being the manner in which the current is generated. Details of this development effort were reported in the first semiannual report on this project. The second inspection methodology is based on rotating permanent magnets. The rotating exciter unit produces strong eddy currents in the pipe wall. At distances of a pipe diameter or more from the rotating exciter, the currents flow circumferentially. These circumferential currents are deflected by pipeline defects such as corrosion and axially aligned cracks. Simple sensors are used to detect the change in current densities in the pipe wall. The second

    2000-07-01

    The Petroleum authority of Thailand (PTT) operates onshore and offshore gas transmission system built in early 1980's power generating industry and increasingly, also the needs of other industrial users and retail customers. The current actual gas demand of 1,600 MMSCFD has a record of customer complaint due to inconsistent heating value of the gas systems. Working closely with specialist, we have conducted gas quality and pipeline flexibility study to examine the gas quality concerns of their existing and future pipeline system. Findings from Phase 1 of the gas quality and pipeline flexibility study were: 1. Low and inconsistent heating values of the gas streams due to the high content of CO{sub 2} and N{sub 2} in the streams: 2. Liquid carry- over in the gas streams to customers: 3. Demand will exceed the onshore existing and parallel pipeline capacity by the year 1999 unless facilities are implemented to reduce the CO{sub 2} content of the sales gas. Phase 2 of the Gas Quality and Pipeline Flexibility study concluded that based on the current gas composition and throughput of the Rayong Facilities, the maximum capacity of the onshore pipeline system is 333.9 trillion BTU's per annum, Based on this capacity and the demand for sales gas, the pipeline capacity will be exceeded by the year 1999 by 50.1 trillion BTU's. We developed 15 case studies which were evaluated based on the following: - Supply / demand criteria; - Technical merit; - Financial and economic merit. Phase 3 of the project is current status, A common header for mixing GSP1, GSP2, GSP3, DPCU and by pass gases prior to being compressed by OCS1 and OCS2 compressors is under construction, The project is undertaken by working closely with 140 customers to use new gas quality. Note: GSP = gas separation plant; OCS = on shore compressor; DPCU - dew point control unit. There are two main gas quality problems that exist in gas quality; PTT's pipeline system.

    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 goal of this project is to develop a Virtual Pipeline System Testbed (VPST) for natural gas transmission. This study uses a fully implicit finite difference method to analyze transient, nonisothermal compressible gas flow through a gas pipeline system. The inertia term of the momentum equation is included in the analysis. The testbed simulate compressor stations, the pipe that connects these compressor stations, the supply sources, and the end-user demand markets. The compressor station is described by identifying the make, model, and number of engines, gas turbines, and compressors. System operators and engineers can analyze the impact of system changes on the dynamic deliverability of gas and on the environment.

    Pressure pipe inspection in nuclear power plants is one of the mandatory regulation items. Comparing to manual ultrasonic inspection, automatic inspection has the benefits of more accurate and reliable inspection results and reduction of radiation disposal. final object of this project is to develop an automatic pipeline inspection system of pressure pipe welds in nuclear power plants. We developed a pipeline scanning robot with four magnetic wheels and 2-axis manipulator for controlling ultrasonic transducers, and developed the robot control computer which controls the robot to navigate along inspection path exactly. We expect our system can contribute to reduction of inspection time, performance enhancement, and effective management of inspection results. The system developed by this project can be practically used for inspection works after field tests. (author)

  15. PLUGGING AND UNPLUGGING OF WASTE TRANSFER PIPELINES

    Energy Technology Data Exchange (ETDEWEB)

    M.A. Ebadian, Ph.D.

    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.

    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

    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)

    1979-01-01

    The bottom-tow technique for installing pipe strings on the seabed and the explosive welding tie-in method complement each other to provide a technically and economically attractive pipeline construction method applicable over a wide range of water depths and weather conditions, including marginal cases where other pipelaying methods would not normally be justified. By using the bottom-tow method, pipe strings up to 20 km long can be transported at an optimum towing speed of about 5 knots and positioned within 1.8 m of the specified tow route. Both techniques can be operated from a single, nonspecialized surface vessel in a variety of projects. By using the bottom-tow/explosive welding method, savings of at least 50% can be achieved, compared with conventional lay-barge techniques, particularly for 10 mi or longer pipelines.

  2. Permanent cathodic protection monitoring systems for offshore pipelines

    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)

    2006-07-01

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

    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.

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

    This paper described research currently being conducted to develop a mechanics-based wrinkle ultimate limit state for evaluating the long-term integrity of wrinkled pipeline segments. Efforts included testing and non-linear finite element analysis (FEA) of small-scale and full-scale wrinkled pipeline segments. The aim of the program was to develop a set of monotonic and cyclic material properties for use in designing a failure assessment procedure. A failure criterion has also been developed to predict the fatigue life of experimental pipeline specimens. An experimental material properties database was developed for several pipeline materials ranging from API grade X60 to X100 steel pipelines. Multiple monotonic tensile tests were conducted for all materials used in the program. Experimental stress-strain curves were used to develop finite element material models during the modelling phase of the project. Complete strain life curves were also obtained. A small scale strip test was developed to predict the fatigue life of strip test specimens. Nonlinear kinematic material models were also developed. Results of the program to date indicate that the finite element method (FEM) model is capable of accurately estimating the cyclic fatigue life of pipelines with wrinkles. It was concluded that the FEM model will also be used to examine the interactions between soil and buried pipelines. 6 refs., 14 figs.

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

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

  16. The inverse electroencephalography pipeline

    Weinstein, David Michael

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

    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.

    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.

    The Pipeline Research Council International has undertaken a multi-year research program to investigate the local buckling (or wrinkling) of onshore pipelines affected by corrosion. Local buckling resistance depends on wall thickness and seems to be considerably reduced by metal-loss defects. Experimental data were lacking, which led to the use of overly conservative assumptions. C-FER and the University of Alberta conducted research in three phases in order to develop local buckling criteria for pipelines with corrosion defects. In Phase 1, the influence of various corrosion defect features was assessed with finite element analysis, and the ranking of key parameters was determined. On this basis, Phase 2 consisted in developing a test matrix and carrying out 10 full-scale tests to collect data. In Phase 3, finite element models were used to analyze over 150 parametric cases and develop criteria for assessing maximum moment and compressive strain limit. These criteria were applied to in-service pipelines with general corrosion features.

    The development of next-generation sequencing has generated high demand for data processing and analysis. Although there are a lot of software for analyzing next-generation sequencing data, most of them are designed for one specific function (e.g., alignment, variant calling or annotation). Therefore, it is necessary to combine them together for data analysis and to generate interpretable results for biologists. This study designed a pipeline to process Illumina sequencing data based on Perl programming language and SGE system. The pipeline takes original sequence data (fastq format) as input, calls the standard data processing software (e.g., BWA, Samtools, GATK, and Annovar), and finally outputs a list of annotated variants that researchers can further analyze. The pipeline simplifies the manual operation and improves the efficiency by automatization and parallel computation. Users can easily run the pipeline by editing the configuration file or clicking the graphical interface. Our work will facilitate the research projects using the sequencing technology.

    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

    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

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

    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)

    2000-01-01

    To explore emission baseline, technically the most difficult issue for Clean Development Mechanism (CDM) project development, as well as to examine whether CDM is a possible way to help Beijing restructure its heating energy consumption, this paper conducts a CDM baseline case study on residential heating in Beijing. Based on investigation, energy consumption forecast and economic analysis of future technology options, the technology benchmark and site-specific baselines for both retrofit projects and new heating projects have been discussed. The results indicate that fuel switching from coal to natural gas can meet the additionality criteria in many cases and will be the main type of CDM project. In addition, it also proves that the technology benchmark and the case-by-case baseline setting approach are applicable for future CDM cooperation projects on heating in Beijing.

    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.

    ENGLISH ABSTRACT: The case of a nuclear engineering project was investigated to establish the relevant success criteria for the development of complex, high-technology systems. The project was first categorised according to an existing scheme, and the Delphi method was used to determine the criteria for project success that apply to this specific case. A framework of project success dimensions was extended to include criteria that are of specific importance for the project under consideration.

    While project efficiency (delivery on time and within budget obviously still needs to be controlled, the results provide empirical evidence for the notion that, for ‘super high tech’ projects, this is relatively less important. The relative importance of the dimensions of success was also evaluated and presented on a timeline stretching from project execution to 10 years after project completion. This provided empirical evidence for certain concepts in the literature.

    Ever since entering ESO in 2006, Spain has made an in-kind contribution invarious fields. In the Pipeline Systems Department (PSD), this contribution hasbeen made to a number of projects, in particular to the CPL (Common Pipeline Library), to the pipelines of the instruments ISAAC, SofI and FORS, and to theintegration of the pipeline for the new VISTA telescope into the DFS (Data FlowSystem) at Paranal. Some of these projects started with the VLT a decade ago, and have experiencedan evolution since, as a consequence of standardization processes, of thesearch of elements in common and, especially in the last couple of years, ofthe efforts to provide the astronomy community with 'science-ready' dataproducts. At the same time, the PSD faces new challenges today, as the dramatic increase in the data volume of the Paranal Observatory since the start of operations of VISTA, or the needs of the pipelines of the future instruments of the E-ELT. In the latter, more concretely, the current status of the CPL is being analyzed, with the goal of establishing the necessary changes to meet those future needs.In this article we introduce briefly these projects and detail the Spanish in-kind contribution to them.

  5. Pipeline bottoming cycle study. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-01

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

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

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

    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.

    The purpose of this article is to create actionable knowledge, making the definition of process improvement projects in health care delivery more effective. 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.

  1. Joint Implementation Analysis: A Case Study of the Japan-China Coke Dry Quenching (CDQ) Project

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    One of the key issues for "Joint Implementation" is how to define a plausible baseline, a necessary benchmark for calculating net Greenhouse Gases (GHGs) emission reductions through a comparative approach. Based on a thorough case study of the China-Japan Coke Dry Quenching (CDQ) project, the first approved pilot project in China under the "Activities Implemented Jointly" (AIJ) framework, the paper not only describes in detail the complete procedure of baseline definition of the case project, but also discusses its approach to baseline determination. Furthermore, cost-benefit analysis of GHGs mitigation is conducted according to the baseline. This empirical case study, based on real AIJ project data, will be beneficial for the development of future projects under Kyoto mechanisms such as "Clean Development Mechanism" and "Joint Implementation".

    2011-01-01

    Requirements are found to change in various ways during the course of a project. This can affect the process in widely different manner and extent. Here we present a case study where-in we investigate the impact of requirement volatility pattern on project performance. The project setting described in the case is emulated on a validated system dynamics model representing the waterfall model. The findings indicate deviations in project outcome from the estimated thereby corroborating to previous findings. The results reinforce the applicability of system dynamics approach to analyze project performance under requirement volatility, which is expected to speed up adoption of the same in organizations and in the process contribute to more project successes.

    The Galactic O-Star Spectroscopic Survey (GOSSS) is an ambitious project that is observing all known Galactic O stars with B < 13 in the blue-violet part of the spectrum with R-2500. It is based on version 2 of the most complete catalog to date of Galactic O stars with accurate spectral types (v1, Ma\\'iz Apell\\'aniz et al. 2004 ;v2, Sota et al. 2008). Given the large amount of data that we are getting (more than 150 nights of observations at three different observatories in the last 4 years) we have developed an automatic spectroscopic reduction pipeline. This pipeline has been programmed in IDL and automates the process of data reduction. It can operate in two modes: automatic data reduction (quicklook) or semi-automatic data reduction (full). In "quicklook", we are able to get rectified and calibrated spectra of all stars of a full night just minutes after the observations. The pipeline automatically identifies the type of image and applies the standard reduction procedure (bias subtraction, flat field c...

  4. Global lateral buckling analysis of idealized subsea pipelines

    2014-01-01

    In order to avoid the curing effects of paraffin on the transport process and reduce the transport difficulty, usually high temperature and high pressure are used in the transportation of oil and gas. The differences of temperature and pressure cause additional stress along the pipeline, due to the constraint of the foundation soil, the additional stress can not release freely, when the additional stress is large enough to motivate the submarine pipelines buckle. In this work, the energy method is introduced to deduce the analytical solution which is suitable for the global buckling modes of idealized subsea pipeline and analyze the relationship between the critical buckling temperature, buckling length and amplitude under different high-order global lateral buckling modes. To obtain a consistent formulation of the problem, the principles of virtual displacements and the variation calculus for variable matching points are applied. The finite element method based on elasto-plastic theory is used to simulate the lateral global buckling of the pipelines under high temperature and pressure. The factors influencing the lateral buckling of pipelines are further studied. Based upon some actual engineering projects, the finite element results are compared with the analytical ones, and then the influence of thermal stress, the section rigidity of pipeline, the soil properties and the trigging force to the high order lateral buckling are discussed. The method of applying the small trigging force on pipeline is reliable in global buckling numerical analysis. In practice, increasing the section rigidity of a pipeline is an effective measure to improve the ability to resist the global buckling.

    The Gaia mission will have a profound impact on our understanding of the structure and dynamics of the Milky Way. Gaia is providing an exhaustive census of stellar parallaxes, proper motions, positions, colors and radial velocities, but also leaves some glaring holes in an otherwise complete data set. The radial velocities measured with the on-board high-resolution spectrograph will only reach some 10 % of the full sample of stars with astrometry and photometry from the mission, and detailed chemical information will be obtained for less than 1 %. Teams all over the world are organizing large-scale projects to provide complementary radial velocities and chemistry, since this can now be done very efficiently from the ground thanks to large and mid-size telescopes with a wide field-of-view and multi-object spectrographs. As a result, automated data processing is taking an ever increasing relevance, and the concept is applying to many more areas, from targeting to analysis. In this paper, I provide a quick overview of recent, ongoing, and upcoming spectroscopic surveys, and the strategies adopted in their automated analysis pipelines.

    2011-05-01

    Full Text Available The objective of the study was to identify the socio-economic and institutional factors which influence the level of awareness of Clean Development Mechanism (CDM projects and in so doing to highlight the policy implications for the stakeholders when designing clean development mechanism projects among smallholder farmers. Findings shows that 23% of the farmers were correctly aware of the project and the results of the ordered logit model indicate that age, gender, education level, group membership, existence of tree farming and contact with extension services was found to influence awareness level of smallholder forest Carbon projects. To assist the community to adapt to climate change and produce sufficiently on a sustainable basis and achieve the desired food security under climate change challenges, the study recommends policies to increase awareness of such agro-environmental initiatives and that of extension providers should distinguish their clientele anchored on vital demographic characteristics such as age and gender. If the probability of younger farmers to be aware this initiative is higher, extension communications should be directed to such age group, particularly during initial stages project information dissemination.

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

    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.

  6. The Use of Volunteers in Local Study Library Projects: A Case Study of the Walter Gardiner Photography Project

    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.

    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

    Full Text Available Problem statement: Achieving projects is primordial in the process of teaching in several disciplines, particularly software engineering courses. However, proposing this learning activity in a context of e-learning is not automatically guaranteed by the current platforms, even unsupported by the existing standards for creating educational content. Approach: Through this study, starting from the model developed in the “XESOP-Jaxe” project to represent the contents of an e-learning course, we tried to propose an improvement in order to formalize a project for learners as a learning object. Results: We grafted our model, formalized in XML Schema, to the “XESOP-Jaxe” schema of the course. Thus, to the elements that could constitute a course, comes a new element called “projet” (project. Conclusion: This model was built and tested within the “XESOP-Jaxe” platform whose goal is to provide an effective solution for creating educational content in compliance with existing standards.

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

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

    2009-10-01

    Full Text Available Abstract Background High-throughput screening of protein-protein interactions opens new systems biology perspectives for the comprehensive understanding of cell physiology in normal and pathological conditions. In this context, yeast two-hybrid system appears as a promising approach to efficiently reconstruct protein interaction networks at the proteome-wide scale. This protein interaction screening method generates a large amount of raw sequence data, i.e. the ISTs (Interaction Sequence Tags, which urgently need appropriate tools for their systematic and standardised analysis. Findings We develop pISTil, a bioinformatics pipeline combined with a user-friendly web-interface: (i to establish a standardised system to analyse and to annotate ISTs generated by two-hybrid technologies with high performance and flexibility and (ii to provide high-quality protein-protein interaction datasets for systems-level approach. This pipeline has been validated on a large dataset comprising more than 11.000 ISTs. As a case study, a detailed analysis of ISTs obtained from yeast two-hybrid screens of Hepatitis C Virus proteins against human cDNA libraries is also provided. Conclusion We have developed pISTil, an open source pipeline made of a collection of several applications governed by a Perl script. The pISTil pipeline is intended to laboratories, with IT-expertise in system administration, scripting and database management, willing to automatically process large amount of ISTs data for accurate reconstruction of protein interaction networks in a systems biology perspective. pISTil is publicly available for download at http://sourceforge.net/projects/pistil.

    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.

    Based on an earlier report indicating that an optimal match for solar energy applications is to preheat hot water used in nursing homes, this paper discusses the construction of a solar water pre-heating system at the Rockwood Terrace Nursing Home in Durham, Ontario. Performance of the system, costs and financial viability are predicted with the use of the RETScreen project management tool. In addition, system requirements and load and energy requirements are also taken into consideration with this tool, thereby ensuring the unique nature of each project. Thirty solar collectors were mounted on steel racks 3 stories above the mechanical room. A heat exchanger, heated by antifreeze, circulates to and from the solar collectors. Potable water is circulated from hot water storage tanks to the heat exchanger. Solar pre-heated water is then piped into a hot water storage tank, with a gas fired water heater heating potable hot water in a recirculation loop. The paper concludes that both Watsun 13.2 and RETScreen are both good predictive tools, having only exceeded actual measured performances of the system and its energy savings by 8 and 9 per cent respectively. 4 refs., 4 figs.

    A common challenge for pipeline designers is the placement and safe operation of pipelines within unstable slopes. Consequently, special design and operation procedures must be created to maintain the integrity of the pipeline through its operating life. Nova Gas Transmission Limited (NGTL) has developed a methodology to monitor pipeline integrity in slow moving (creeping) unstable slopes. This methodology uses Pipeline-Soil Interaction models to produce parameters that are in turn placed in Pipeline Integrity Assessment Techniques such as finite element analysis. For slope movements, pipeline integrity is based on pipeline strain criteria that are established from regulated codes or NGTL`s risk-based criteria. The result is that pipe strain can be estimated over time given a particular soil type and predicted ground movement. The ability to predict when a pipeline is reaching a critical strain allows NGTL to effectively quantify the risk and associated cost for various remedial measured based on a given operating life (life-cycle cost). These remedial measures can take the form of strain relieving outages, re-routing of the pipeline, directional drilling or conventional geotechnical remedial practices (dewatering, slope grading, buttressing, etc.). Two case studies are presented detailing this present state-of-practice methodology at NGTL.

    2010-07-01

    The pipelines of the Magallanes region are operated by Empresa Nacional del Petroleo (ENAP), a Chilean government company. Most of these pipelines were constructed in the 1960s and 1970s and are over 30 years of age. A pipeline integrity management program was initiated in the 1990s. Its first phase consisted in data gathering and high-level risk assessment. In-line inspections were then performed in the pipelines that were considered to be most at risk. Each inspection was followed with an integrity assessment designed to identify features that would require further investigation or repair. This included a pipeline-specific risk assessment, a defect assessment, and an estimation of corrosion growth rates. Most inspections were performed with MFL technology; a case study is shown where a pipeline was inspected three times with the same technology (in 2002, 2006 and 2009). The major threat in the Magallanes region is external corrosion, while some other risks such as third-party activities or ground instability are low.

    Parallel pipelines are frequently installed over long distances, due to the difficulty in creating or maintaining the required corridor. This implies that a release in one pipeline can seriously affect another one. The main risks associated with this domino effect are erosion by fluid-sand jets and the thermal action of jet fires. In this paper a survey has been performed on the accidents that have occurred, and the diverse associated domino sequences are analyzed. The probability of occurrence of domino effect is a function of the location of the hole, the jet direction and solid angle, the diameter of both pipelines and the distance between them. A mathematical model has been developed to estimate this probability. The model shows how the probability of domino effect decreases with the distance and diameter of the source pipe, and increases with the diameter of the target pipe. Its frequency can be estimated from this probability and from the frequency of the initiating pipe failure plus, in the case of jet fire impingement, the probability of ignition. The frequency of the target pipe failure thus calculated, always higher than its individual frequency, allows a more realistic risk analysis. Copyright © 2015 Elsevier B.V. All rights reserved.

    Abdallah Ali Imetieg

    2015-04-01

    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.

    2014-01-01

    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.

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

    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.

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

    Layered software architecture contains several intra-layer and inter-layer dependencies. Each layer depends on shared components making it difficult to release a code change, bug fix or feature without exhaustive testing and having to build the entire software code base. This paper proposed self-contained, cross-cutting pipeline architecture (SCPA) that is independent of existing layers.

  3. Projections of HIV infections and AIDS cases to the year 2000.

    1990-01-01

    After the recognition of AIDS (acquired immunodeficiency syndrome) in the early 1980s, uncertainty about the present and future dimensions of HIV (human immunodeficiency virus) infection led to the development of many models to estimate current and future numbers of HIV infections and AIDS cases. The Global Programme on AIDS (GPA) of the World Health Organization (WHO) has developed an AIDS projection model which relies on available HIV seroprevalence data and on the annual rate of progression from HIV infection to AIDS for use in areas where reporting of AIDS cases is incomplete, and where scant data are available to quantify biological and human behavioural variables. Virtually all models, including the WHO model, have projected large increases in the number of AIDS cases by the early 1990s. Such short-term projections are considered relatively reliable since most of the new AIDS cases will develop in persons already infected with HIV. Longer-term prediction (10 years or longer) is less reliable because HIV prevalence and future trends are determined by many variables, most of which are still not well understood. WHO has now applied the Delphi method to project HIV prevalence from the year 1988 to mid-2000. This method attempts to improve the quality of the judgements and estimates for relatively uncertain issues by the systematic use of knowledgeable "experts". The mean value of the Delphi projections for HIV prevalence in the year 2000 is between 3 and 4 times the 1988 base estimate of 5.1 million; these projections have been used to obtain annual estimates of adult AIDS cases up to the year 2000. Coordinated HIV/AIDS prevention and control programmes are considered by the Delphi participants to be potentially capable of preventing almost half of the new HIV infections that would otherwise occur between 1988 and the year 2000. However, more than half of the approximately 5 million AIDS cases which are projected for the next decade will occur despite the most

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

    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.

  6. Economic model of pipeline transportation systems

    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.

  7. REMOTE DETECTION OF INTERNAL PIPELINE CORROSION USING FLUIDIZED SENSORS

    Energy Technology Data Exchange (ETDEWEB)

    2005-10-31

    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

    The growth of oil-products demand in future years is leading the Yemen Arab Republic (Y.A.R.) to improve the distribution network for the products by constructing a pipeline system. Petroleum products are currently distributed by road tankers only between the receiving terminals and the main cities, which represent the most important consumption centers, together with new industrial plants such as cement factories, power plants, etc. The technical design and economic and financial feasibility study of the project was entrusted to Omnium Technique des Transports par Pipelines (OTP). The scope covers the setting up in the Y.A.R. of the basic equipment for the supply, storage, and land transportation of petroleum products with a view to: Meeting the national demand for the next 25 years. Providing an adequate strategic reserve of petroleum products with a total storage capacity amounting to 3 months of consumption. The only exception in the transportation of the petroleum products will involve heavy fuel oil which will continue to be transported by road tankers. This article describes the basic facilities which have to be installed before the start-up of the projected network. The project includes a marine terminal in Salif and a pipeline to Sana'a with the related storage, truck loading, and pumping facilities for white products and gas oil which will be transported by pipeline.

  10. Development Of A Centrifugal Hydrogen Pipeline Gas Compressor

    Energy Technology Data Exchange (ETDEWEB)

    Di Bella, Francis A. [Concepts NREC, White River Junction, VY (United States)

    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.

    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.)

    The Cartier Pipeline connects eastern Canadian natural gas supply with the Canadian transmission grid and central Canadian markets. This stand-alone pipeline also involves equal partnership between Alberta's Enbridge Consumers Gas and Quebec's Gaz Metropolitain to deliver offshore Atlantic gas to markets in Quebec and eastern Canada. The inservice date for the proposed pipeline is November 2004. The $270 million dollar project will require 262 km of pipeline in Quebec with an annual transportation capacity of 67 Bcf initially. Contracted commitments so far include 30 Bcf/year from Gaz Metropolitain and the same from Enbridge. Cartier offers attractive, base load, long term, complementary market diversification for Atlantic production. It also provides producers with a competitive channel to Ontario storage. In addition, the pipeline will contribute to lower tolls in Canada and the overall path to Dracut (Boston). Several graphs depicting expected costs of delivered gas supplies to Montreal were also included with this power point presentation. tabs., figs.

    Full Text Available ABSTRACT The interorganizational cooperation, through joint efforts with various actors, allows the high-tech companies to complement resources, especially in R&D projects. Collaborative projects have been identified in many studies as an important strategy to produce complex products and services in uncertain and competitive environments. Thus, this research aims at deepening the understanding of how the development dynamics of a collaborative R&D project in an industry of high technology occur. In order to achieve the proposed objective, the R&D project of the first microcontroller in the Brazilian semiconductor industry was defined as the object of analysis. The empirical choice is justified by the uniqueness of the case, besides bringing a diversity of actors and a level of complementarity of resources that were significant to the success of the project. Given the motivation to know who the actors were and what the main forms of interorganizational coordination were used in this project, interviews were carried out and a questionnaire was also made, besides other documents related to the project. The results presented show a network of nine actors and their roles in the interorganizational collaboration process, as well as the forms of social and temporal overlapping, used in the coordination of collective efforts. Focusing on the mechanisms of temporal and social integration highlighted throughout the study, the inclusion of R&D projects in the typology for interorganizational projects is proposed in this paper, which was also proposed by Jones and Lichtenstein (2008.

    Full Text Available Construction projects play an important role in infrastructure projects in developing countries. According to type, size, and complexity of the project, the number and importance of each risk could be different and many projects cannot reach the project goals due to exposure to multiple risks. Many papers have been published on the subject of risk management in construction projects; unfortunately most of them have not been implemented in practical conditions. The aim of this study is to identify and prioritize risks in construction projects. The classical approach used probability and impact for risk assessment, but these criteria do not sufficiently address all aspects of projects risks and there might be a relationship between different criteria. This study proposes the hierarchical dependencies between criteria. A case study of construction project is presented to illustrate performance and usage of the proposed model. Utilizing library studies and interview with experts, managers, and specialists, decision criteria were identified through brain storming. Risks were categorized by the experts into eleven risks. Important risks were evaluated based on the fuzzy ANP, fuzzy DEMATEL, and fuzzy TOPSIS methods. The proposed model is more suitable than the traditional decision-making methods in prioritizing risk concerning cost, time, and quality.

    Full Text Available Six Sigma is a strategic approach of significant value in achieving overall excellence. It helps to accomplish the organizations strategic aim through the effectual use of project controlled methodology. As Six Sigma is a project controlled approach, it is necessary to prioritize projects which give utmost economic benefits to the firm. In real practice, Six Sigma projects selection is very tough assignment because poor project selection also happens even in the well-managed organizations and this can weaken the success and trustworthiness of the Six Sigma practice. The present study aims to develop a project selection approach based on a combination of fuzzy and MADM technique to help organizations determine proper Six Sigma projects and identify the priority of these projects mainly in automotive companies. VIKOR and TOPSIS methods have been used to select the proper Six Sigma project composed with fuzzy logic. In this context, seven critical parameters have been considered for selection of finest alternative. The weights of evaluation criteria are obtained using the MDL (modified digital logic method and final ranking is calculated through primacy index obtained by using fuzzy based VIKOR and TOPSIS methodology. A factual case study from automotive industry is used to investigate the efficacy of the planned approach.

    2010-01-01

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

    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.

    2009-06-02

    This project builds on the results of previously funded research by integrating data and software that had been previously used in building resources used in the preparation of Bergey?s Manual of Systematic Bacteriology, 2nd Edition (Volumes 1 & 2A-C) and the Ribosomal Database Project-II (RDP-II) so as to both enhance the value of the data and create a pipeline approach to keeping the data current. Earlier, we demonstrated the value of using exploratory data analysis (EDA) to visualize large sets of sequence data (notably SSU rRNA gene sequences used in constructing a comprehensive phylogeny of prokaryotes. While the Self- Organizing Self-Correcting Classification (SOSCC) algorithms we developed were computationally efficient and useful for unraveling problems within the underlying data (e.g., identification of annotation errors, detection of unresolved synonymies, taxonomic and nomenclatural errors), bottlenecks at the preprocessing stage limited deployment of our applications as tools for end-users. To overcome the bottlenecks (which included hand alignment and computation of large matrices of pair-wise evolutionary distances), we proposed building a data pipeline between the ?Taxomatic? application and RDP-II. The objectives were to accelerate the production and distribution of the updated versions of the prokaryotic taxonomy in lock-step with publication of new taxa and rearrangement of existing taxa, and to distribute these data more readily with the RDP-II and and other stakeholders in the community. A related goal of the current project is to deploy our visualization techniques as an interactive web application by which end-users can view manipulate, and select datasets of particular interest based upon phylogenetic and genomic information, access sequence data, and ultimately the scientific literature where the original observations were made and those that build on the original observations. The Taxomatic is a web-based tool to visualize distance matrices

    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.

    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.

    2016-01-01

    The development of automated servers to predict the three-dimensional structure of proteins has seen much progress over the years. These servers make calculations simpler, but largely exclude users from the process. In this study, we present the PRotein Interactive MOdeling (PRIMO) pipeline for homology modeling of protein monomers. The pipeline eases the multi-step modeling process, and reduces the workload required by the user, while still allowing engagement from the user during every step. Default parameters are given for each step, which can either be modified or supplemented with additional external input.

    The development of automated servers to predict the three-dimensional structure of proteins has seen much progress over the years. These servers make calculations simpler, but largely exclude users from the process. In this study, we present the PRotein Interactive MOdeling (PRIMO) pipeline for homology modeling of protein monomers. The pipeline eases the multi-step modeling process, and reduces the workload required by the user, while still allowing engagement from the user during every step. Default parameters are given for each step, which can either be modified or supplemented with additional external input. PRIMO has been designed for users of varying levels of experience with homology modeling. The pipeline incorporates a user-friendly interface that makes it easy to alter parameters used during modeling. During each stage of the modeling process, the site provides suggestions for novice users to improve the quality of their models.

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

    Energy Technology Data Exchange (ETDEWEB)

    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.

  10. Assessment of pipeline stability in the Gulf of Mexico during hurricanes using dynamic analysis

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Pipelines are the critical link between major offshore oil and gas developments and the mainland. Any inadequate on-bottom stability design could result in disruption and failure, having a devastating impact on the economy and environment. Predicting the stability behavior of offshore pipelines in hurricanes is therefore vital to the assessment of both new design and existing assets. The Gulf of Mexico has a very dense network of pipeline systems constructed on the seabed. During the last two decades, the Gulf of Mexico has experienced a series of strong hurricanes, which have destroyed, disrupted and destabilized many pipelines. This paper first reviews some of these engineering cases. Following that, three case studies are retrospectively simulated using an in-house developed program. The study utilizes the offshore pipeline and hurricane details to conduct a Dynamic Lateral Stability analysis, with the results providing evidence as to the accuracy of the modeling techniques developed.

  11. Survival of the project: a case study of ICT innovation in health care.

    2015-05-01

    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.

    Offshore pipeline technology coprises a spectrum of technologies within seabed mapping, design, materials, construction, inspection and maintenance. This paper deals with some of the recent developments, characterised by achievements within two specific projects on the Norwegian continental shelf. These developments concern the Troll oil pipeline and the Haltenbank projects. These are the use of advanced subsea mapping and position technology, hydraulic flow modelling simulating unique flow conditions inside a deep and narrow fjord, control of multiple free span behaviour by use of advanced design methology, use of strain based criteria to reduce large scale seabed correction works, high precision pipeline installation in deep weater involving guided laying to ensure the correct position of the pipeline across pre-installed gravel burns and at lateral counteracts, and a midline tie-in concept comprising an above-water welded tie-in of a prefabricated bend section and on bottom installation of hydraulic operated mechanical connectors specially developed for diverless repair contingency in deep waters. 10 figs.

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

    Science.gov (United States)

    Widener, Patricia

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

    During a pipeline life cycle, some significant changes in the population may happen along its route. Such changes are indirectly evaluated by the increase in the amount of buildings constructed along the route, which determines the so called Location Class. Such changes, after licensing, provoke differences between what is required by the standards and what is actually done. This work has two goals. One is to study the requirements of international standards and legislations as well as some solutions used in the United States, Canada, United Kingdom and Netherlands. This goal intends to provide some technical bases for a comparative analysis on how the location class changes, during the life cycle of a pipeline, are treated in each country. Another goal is to present a risk-based methodology for the guideline development which can be used in decision-making concerning what to do in case of any location class change. Particularly, it has given special attention to the requirements which are imposed for the pipeline operational license continuation. This work is of supreme importance for the Brazilian pipeline segment, since the existing Brazilian design standard, ABNT NBR12712 for transmission and distribution pipeline design, does not deal with that issue. Moreover, a summary of the main solutions found in those countries together with a guideline, customized for the Brazilian reality, is presented. (author)

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

    2016-09-01

    Assistance algorithms for medical tasks have great potential to support physicians with their daily work. However, medicine is also one of the most demanding domains for computer-based support systems, since medical assistance tasks are complex and the practical experience of the physician is crucial. Recent developments in the area of cognitive computing appear to be well suited to tackle medicine as an application domain. We propose a system based on the idea of cognitive computing and consisting of auto-configurable medical assistance algorithms and their self-adapting combination. The system enables automatic execution of new algorithms, given they are made available as Medical Cognitive Apps and are registered in a central semantic repository. Learning components can be added to the system to optimize the results in the cases when numerous Medical Cognitive Apps are available for the same task. Our prototypical implementation is applied to the areas of surgical phase recognition based on sensor data and image progressing for tumor progression mappings. Our results suggest that such assistance algorithms can be automatically configured in execution pipelines, candidate results can be automatically scored and combined, and the system can learn from experience. Furthermore, our evaluation shows that the Medical Cognitive Apps are providing the correct results as they did for local execution and run in a reasonable amount of time. The proposed solution is applicable to a variety of medical use cases and effectively supports the automated and self-adaptive configuration of cognitive pipelines based on medical interpretation algorithms.

  16. Frequency spectrum method-based stress analysis for oil pipelines in earthquake disaster areas.

    Directory of Open Access Journals (Sweden)

    Xiaonan Wu

    Full Text Available When a long distance oil pipeline crosses an earthquake disaster area, inertial force and strong ground motion can cause the pipeline stress to exceed the failure limit, resulting in bending and deformation failure. To date, researchers have performed limited safety analyses of oil pipelines in earthquake disaster areas that include stress analysis. Therefore, using the spectrum method and theory of one-dimensional beam units, CAESAR II is used to perform a dynamic earthquake analysis for an oil pipeline in the XX earthquake disaster area. This software is used to determine if the displacement and stress of the pipeline meet the standards when subjected to a strong earthquake. After performing the numerical analysis, the primary seismic action axial, longitudinal and horizontal displacement directions and the critical section of the pipeline can be located. Feasible project enhancement suggestions based on the analysis results are proposed. The designer is able to utilize this stress analysis method to perform an ultimate design for an oil pipeline in earthquake disaster areas; therefore, improving the safe operation of the pipeline.

    Full Text Available This case study describes the bottom-up formation of a regional project for restoring a reservoir. Land use changes in the upper Vltava river basin caused the eutrophication of Orlík reservoir, which resulted in water blooms, which in association with socio-economic changes caused a decline in tourism in this region and serious difficulties for local people. The study examines how public awareness helped in the establishment of a restoration project, its framework and strategy. Regional governance of the project management took into consideration both knowledge-based solutions and the interests of local people and municipalities. The project has the potential for resolving both environmental and socio-economic problems and providing a sustainable win-win strategy for the region, residents, tourists and stakeholders.

    Full Text Available Context Lymphoepithelial cysts of the pancreas show various presentations on imaging studies often making a differential diagnosis difficult. Case report A 58-year-old man was admitted to our hospital with epigastric discomfort and abdominal bloating. Abdominal US was carried out and demonstrated a cystic lesion 5 cm in diameter which included an intracystic projection into the pancreatic body. This intracystic projection was also seen on CT and MR images. On FDG-PET images, the projection was positively visualized. Since we could not exclude a pancreatic cystic neoplasm, a distal pancreatectomy was performed. Postoperative pathological examination demonstrated that the lesion was a lymphoepithelial cyst of the pancreas. There were no atypical cells in the intracystic projection. Conclusion Resection is inevitable when a true pancreatic neoplasm cannot be excluded.

    2016-02-01

    The crucial role evaluation can play in the co-development of project design and its implementation will be addressed through the analysis of a case study, the Green Communities (GC) project, funded by the Italian Ministry of Environment within the EU Interregional Operational Program (2007-2013) "Renewable Energy and Energy Efficiency". The project's broader goals included an attempt to trigger a change in Italian local development strategies, especially for mountain and inland areas, which would be tailored to the real needs of communities, and based on a sustainable exploitation and management of the territorial assets. The goal was not achieved, and this paper addresses the issues of how GC could have been more effective in fostering a vision of change, and which design adaptations and evaluation procedures would have allowed the project to better cope with the unexpected consequences and resistances it encountered. The conclusions drawn are that projects should be conceived, designed and carried out as dynamic systems, inclusive of a dynamic and engaged evaluation enabling the generation of feedbacks loops, iteratively interpreting the narratives and dynamics unfolding within the project, and actively monitoring the potential of various relationships among project participants for generating positive social change.

  3. Existing Whole-House Solutions Case Study: Greenbelt Homes, Inc. Pilot Retrofit Project

    2015-06-01

    In the fall of 2010, a multiyear pilot energy efficiency retrofit project was undertaken by Greenbelt Homes, Inc., (GHI) a 1,566 home cooperative of circa 1930 and 1940 homes in Greenbelt, Maryland. GHI established this pilot project to serve as a basis for decision making for the rollout of a community-wide upgrade program that will incorporate energy efficiency improvements to the building envelope and mechanical equipment. With the community upgrade fully funded by the cooperative through their membership without outside subsidies, this project presents a unique opportunity to evaluate and prioritize the wide range of benefits of high-performance retrofits based on member experience with and acceptance of the retrofit measures implemented during the pilot project.

    Major transmission pipelines run through Ukraine carrying crude oil from Russia to Central and Western Europe. These pipelines were built as a socialist joint project during the Soviet era. During this period, however, no adequate maintenance was performed on these pipelines. After the collapse of the Soviet Union, the independent states of Belarus and Ukraine evolved and the oil pipelines duly passed into their ownership. In Ukraine, the Ukrainian state joint stock company Druzhba took over the western section of the oil transit pipelines in its capacity as both owner and operator. Since these pipelines are of major significance for the purpose of supplying oil to Western Europe and Druzhba did not have the relevant resources to introduce a state-of-the-art inspection and maintenance programme, the European Union decided to sponsor an audit which was funded within the context of the TACIS Programme.

    For every mobilization of a new enterprise it is necessary to quickly obtain the greatest amount of relative information in regards to location and availability of infra-structure, logistics, and work site amenities. Among this information are reports elaborated for management of the enterprise, (organizational chart, work schedule, objectives, contacts, etc.) as well as geographic anomalies, social-economic and culture of the area to be developed such as territorial extension, land aspects, local population, roads and amenities (fuel stations ,restaurants and hotels), infra-structure of the cities (health, education, entertainment, housing, transport, etc.) and logistically the distance between cities the estimated travel time, ROW access maps and notable points, among other relevant information. With the idea of making this information available for everyone involved in the enterprise, it was elaborated for GASCAC Spread 2A a rapid guide containing all the information mentioned above and made it available for all the vehicles used to transport employees and visitors to the spread. With this, everyone quickly received the majority of information necessary in one place, in a practical, quick, and precise manner, since the information is always used and controlled by the same person. This study includes the model used in the gas pipeline GASCAC Spread 2A project and the methodology used to draft and update the information. Besides the above, a file in the GIS format was prepared containing all necessary planning, execution and tracking information for enterprise activities, from social communication to the execution of the works previously mentioned. Part of the GIS file information was uploaded to Google Earth so as to disclose the information to a greater group of people, bearing in mind that this program is free of charge and easy to use.

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

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

    Full Text Available Several studies have documented benefits of prefabrication system (prefab compared to the traditional building system (TBS. However, the documented benefits have been anecdotal or fragmented with reports of isolated case study projects. Few studies have looked at the objectively quantified benefits from statistical significance point of view and across building types in New Zealand. This study contributes to filling this knowledge gap by analyzing cost and time-savings, and productivity improvement achievable by the use of prefab in place of the TBS. Records of completion times and final contract values of 66 building projects implemented using prefab in Auckland were collected. The building types included commercial, houses, apartments, educational, and community buildings. The project details included final contract sums, completion dates, gross floor areas, and number of floors. Based on these details, the equivalent completion times and the final cost estimates for similar buildings implemented using the TBS were obtained from the Rawlinsons construction data handbook and feedback from some designers and contractors. Marginal productivity outcome for each building project was computed as the product of the cost and time-savings achieved using the prefab. Results showed that the use of prefab in place of TBS resulted in 34% and 19% average reductions in the completion times and costs, respectively. This also translated to overall 7% average improvement in the productivity outcomes in the building projects. Univariate ANOVA-based hypothesis test results showed that ‘building type’ had no significant effects on the cost and productivity improvement outcomes, but had significant effect on the time savings analyzed in the case study projects. The greatest productivity gain of 11% was achieved in house projects. These evidence-based results could guide optimized use of prefab for specific building application.

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

    The objective of the investigation is to develop a physically based understanding of the mechanisms of stress corrosion cracking (SCC) in pipeline steels by applying advanced fracture surface and electrochemical characterization techniques to samples taken from fielded pipeline. The investigations found that the effect of pressure fluctuations on the propagation of stress corrosion cracks was readily evident from an analysis of the topographies of conjugate fracture surfaces. Substantial crack blunting was produced under normal pipeline operating conditions. Corrosion deposits were removed from the fracture surfaces of a stress corrosion crack in a pipeline specimen recovered from service. The topography of the underlying metal surface appears to be preserved with little corrosion damage after crack formation. This allowed the cracking process to be reconstructed from the surface topography. In some cases, deposits on the fracture surfaces of stress corrosion cracks contain significant concentrations of metallic elements that are not found in pipeline steels but are likely to be commonplace in the surrounding environment.

    High pressure and high temperature (HP/HT) offshore pipelines are frequently subjected to lateral buckling due to excessive compressive axial force. Several control processes have been designed such as sleepers to reduce lateral buckling. This paper investigated the effect of the introduction of sleepers as buckle triggers on the behavior of HP/HT pipelines. A 3D finite element analysis using ABAQUS software was performed to simulate concrete sleepers and a profile of the seabed. The analysis criteria were the buckling amplitude, Von Mises stress, equivalent plastic strain and the effective axial force on the pipeline. A case study for HP/HT pipeline was been carried out based on installation surveys. Comparisons between the results from a model without buckle trigger and those from a model with buckle trigger were carried out. It was found that the change to the support structure, adding a buckle trigger, affected the behaviour of the pipeline considerably.

    Inspection and maintenance are a significant part of pipeline operations costs. The objective of this work is to present the results obtained with the application of Risk-Based Inspection to two gas pipelines operated by TRANSPETRO. Based on the current state of knowledge about the degradation mechanisms acting on either pipeline and their respective operating conditions, the RBI study recommended that both be inspected next year. Alternatively in one case, the study lays out the conditions by which the pipeline inspection can be postponed to 2007. TRANSPETRO had already decided to inspect the other pipeline this year (for reasons not related to this study) and therefore, the RBI approach is going to be re-applied after the new inspection results are available. This application will set the date for the next inspection. (author)

    Recent reports place pipeline corrosion costs in North America at seven billion dollars per year. Pitting corrosion causes the higher percentage of failures among other corrosion mechanisms. This has motivated multiple modelling studies to be focused on corrosion pitting of underground pipelines. In this study, a continuous-time, non-homogenous pure birth Markov chain serves to model external pitting corrosion in buried pipelines. The analytical solution of Kolmogorov's forward equations for this type of Markov process gives the transition probability function in a discrete space of pit depths. The transition probability function can be completely identified by making a correlation between the stochastic pit depth mean and the deterministic mean obtained experimentally. The model proposed in this study can be applied to pitting corrosion data from repeated in-line pipeline inspections. Case studies presented in this work show how pipeline inspection and maintenance planning can be improved by using the proposed Markovian model for pitting corrosion.

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

  20. Developing Routines in Large Inter-organisational Projects: A Case Study of an Infrastructure Megaproject

    Directory of Open Access Journals (Sweden)

    Therese Eriksson

    2015-08-01

    Full Text Available General management research has increasingly recognised the significance of routines in organisational performance. Among organisational tasks, megaprojects depend more on routines selected and created within the project than standard, small-scale projects do, owing largely to their size, duration, and uniqueness. Within this context, the present paper investigates how project routines were established and developed during the early design phase of an inter-organisational megaproject. A case study of a large public infrastructure project was conducted, in which data were collected during observations, semi-structured interviews, and project document studies over the course of three years. Results of analysis revealed that the client exerted the greatest impact on choice of routines and that the temporary nature of tasks limited efforts to fine-tune routines. Changes in routines were primarily reactive to new knowledge concerning project needs. The findings suggest that meta-routines to consciously review routines should be used to a greater extent and designed to capture supplier experiences as well.

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

    1996-09-01

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

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

    The social environmental assessment consists in an instrument of planning which principal objective is to know the social ambient that will be changed by the PETROBRAS' pipe undertakings, that are planning to be implemented and will be analyzed by the licensers environmental organs. When pipeline projects are planned, their route cross some regions and ecological sensitive areas, therefore, the attitude of consider the social environmental aspects at the planning stage through the use of valuation instruments, anticipating, the potential social and environmental impacts, assumes more importance in integrating management of these undertakings. This presentation has the main objective to stand out the relevance of the social environmental assessment realization as preliminary knowledge base to the undertakings, since the research results developed represents a support of information about the regions where the undertakings install themselves in distinct stages: environmental permits, assembly and construction and operating. The social environmental assessment of the project named GASBEL II is presented as a case study once it allow to observe a gas pipeline transport project to be implemented at different regions and areas. The Pipeline will cross two different federal states, where the local research boarded many communities with different ways and conditions of life, territory use, cultural expressions and other aspects.

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

    2003-07-01

    The United States will continue to look to Canada and Alaska for a significant part of its natural gas supply in an effort to meet its growing demand for energy. The United States depends on Canadian gas as a reliable and secure supply of energy, and is therefore examining natural gas markets and the wide range of supply opportunities. This presentation highlighted changes in cross border natural gas trade in North America and noted that 94 per cent of natural gas going to the United States from Canada is shipped via pipeline. On the liquefied natural gas (LNG) front, U.S. exports to Mexico now exceed imports, but import volumes from Trinidad and Nigeria are increasing as expected. Total import volumes in 2001 surpassed the previous year. A look at the infrastructure of LNG in the United States was also presented along with the advantages and limitations of each option. Cost comparisons were also presented. It was noted that any import or LNG project would result in unique economics. LNG projects are now cheaper because of better engineering, economies of scale and better pipeline economics. The U.S. National Energy Policy recommends that the pipeline to bring Alaskan gas to U.S. markets should be constructed as soon as possible. It was emphasized that any project to ship natural gas from Alaska to the lower 48 will need to work closely with Canada in order to be successful. 15 figs.

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

    Full Text Available For technology-orientated enterprises that operate project-based businesses, the goal-oriented allocation of scarce marketing resources has great potential to help consolidate their competitive position. An important precondition for goal-oriented management is the identification of the most valuable customers. This enables technology-orientated enterprises to segment markets in order to make tactical marketing decisions. This theorybased paper aims to develop and test a holistic customer ranking model. By deploying the five steps presented in this paper, customer relationship managers are better able to identify and to rank their customers in project-based businesses. A case study provides an example of the application of the method from the automotive industry in Austria. The experiences derived from this case study show that using a customer ranking framework is a crucial factor for enterprises in narrow technology markets to be successful and to achieve their corporate goals.

    The experience of PETROBRAS's performance, when the implantation of the province of Urucu, in the City of Coari, state of Amazon, was constructed on empirical bases and it had as a support landmark the lines of direction dictated in 1988 for famous scientists who acted directly in the Amazon Region. The application of these lines of direction gave support to the implantation of essential activities, such as a fishery of changes, the recovery of sanded small rivers, prevention of spills and the opening of chances for research in that further and little known basin of the Urucu River. The convergence was that PETROBRAS made use of the logistic that the scientists needed; and they made use of the knowledge that the company needed. It was just necessary to adjust the language. The results had been very effective and the province of Urucu became the pioneer and the most expressive unit in environmental management in PETROBRAS. In 1999 the Project PIATAM was implanted: Potential Impacts and Risks of the Transport of Oil and Gas in Amazon, taking care of demands of the future transport of the natural gas to Manaus for gas-pipeline, that became possible in 2003 thanks to the support of the research, whose results had fully taken care of the demands of the environmental licensing of the workmanship. The current work synthesizes the bases of knowledge and the results gotten with the application of these bases in a project of construction of a gas-pipeline of 652 kilometers in full Amazonian forest. In the construction phase, one more time the integration with the scientific community was essential to guarantee the application of the concepts of environment in the workmanship of the Gas-pipeline Urucu - Manaus, with advising of teams from the INPA, like Limnology and of combat the tropical illnesses, as the malaria. Another point of support was the partnership with the Secretariat of Sustainable Development of Amazon in an Accord of application of resources, in 135

    Full Text Available Companies face high market demand and to remain competitive they need to invest in the relationship with their customers. Customer Relationship Management (CRM implies not only a new use of a tool but also a changing of its strategical approach to the market. As seen in previous studies, CRM projects are very likely to fail, however, actions can be taken to help overcome these problems, such as proper knowledge management integration. With this study we are able to answer the following research question: how the company can use knowledge management in a CRM project adoption? In order to answer this question, after a literature review, a case study was conducted. Data collection was carried out through direct observation in the company, with the analysis of documents, and interviews. We can observe that there are a set of knowledge management activities that can help the adoption of CRM projects, even if there is no formal policy for knowledge management in the group or for this specific project. Knowledge sharing is seen as an enabler of better results for CRM projects.

    Full Text Available The long-term sustainable provision of new and high quality maintained road stock is vitally important, especially in times of economic constraint such as Europe is currently experiencing. The Private Finance Initiative (PFI is one method of financing such large-scale, capital intensive projects. An important aspect of this form of financing projects is that the risks are borne not only by the sponsors but are shared by different types of investors such as equity holders, debt providers, and quasi-equity investors. Consequently, a comprehensive and heuristic risk management process is essential for the success of the project. The proposition made within this paper is that the PFI mechanism provides a Value-for-Money and effective mechanism to achieve this. The structure of this PFI finance and investment on a particular road project therefore enables all project stakeholders to take a long-term perspective. This long-term perspective is reflected in the mechanism of a case study of UK – Class A trunk roads which are examined in detail. This paper presents a novel solution to a modern dilemma.

    2017-05-01

    Production conditions in today’s world require software support at every stage of production and development of new products, for quality assurance and compliance with ISO standards. In addition to ISO standards such as usual metrics of quality, companies today are focused on other optional standards, such as CMMI (Capability Maturity Model Integrated) or prescribing they own standards. However, while there is intensive progress being made in the PM (project management), there is still a significant number of projects, at the global level, that are failures. These have failed to achieve their goals, within budget or timeframe. This paper focuses on checking the role of software tools through the rate of success in projects implemented in the case of internationally manufactured electrical equipment. The results of this research show the level of contribution of the project management software used to manage and develop new products to improve PM processes and PM functions, and how selection of the software tools affects the quality of PM processes and successfully completed projects.

    Research service cores at academic health centers are important in driving translational advancements. Specifically, biostatistics and research design units provide services and training in data analytics, biostatistics, and study design. However, the increasing demand and complexity of assigning appropriate personnel to time-sensitive projects strains existing resources, potentially decreasing productivity and increasing costs. Improving processes for project initiation, assigning appropriate personnel, and tracking time-sensitive projects can eliminate bottlenecks and utilize resources more efficiently. In this case study, we describe our application of lean six sigma principles to our biostatistics unit to establish a systematic continual process improvement cycle for intake, allocation, and tracking of research design and data analysis projects. The define, measure, analyze, improve, and control methodology was used to guide the process improvement. Our goal was to assess and improve the efficiency and effectiveness of operations by objectively measuring outcomes, automating processes, and reducing bottlenecks. As a result, we developed a web-based dashboard application to capture, track, categorize, streamline, and automate project flow. Our workflow system resulted in improved transparency, efficiency, and workload allocation. Using the dashboard application, we reduced the average study intake time from 18 to 6 days, a 66.7% reduction over 12 months (January to December 2015).

    Full Text Available A shortage of physicians in the United States has been long projected. Because of predictions of retirement among the aging pathology workforce, there is an anticipated shortage of pathologist as well. To address the pathology workforce shortage among pathologists, the Association of Pathology Chairs assembled a subcommittee of the Association of Pathology Chairs Advocacy Committee to explore ways to identify the strengths, weaknesses, opportunities, and threats to the pathology workforce. One opportunity to encourage strong candidates to pursue pathology as a career is to explore possibility to revisit advanced credit for the post-sophomore fellowship. A survey that was designed to understand the post-sophomore fellowship training better was distributed on the listserv of the Program Directors Section of the Association of Pathology Chairs. A review of the literature on post-sophomore fellowship programs is presented in light of the findings from this survey. Many post-sophomore fellowship programs are run similar to a first-year resident experience, although programs show great diversity in curriculum, including some programs that focus on research. Post-sophomore fellowships attract medical students to the area of pathology and tend to end up in academic and research positions. A second survey of program directors served as an opinion poll of challenging issues that affect residency training. From the second opinion poll, most program directors feel that residents can use additional training to improve the outcome of our future pathologists.

    2012-01-01

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

    Full Text Available Abstract Background Maize is the most important staple food in Kenya; any reduction in production and yield therefore often becomes a national food security concern. To address the challenge posed by the maize stem borer, the Insect Resistant Maize for Africa (IRMA agricultural biotechnology public-private partnership (PPP project was launched in 1999. There were, however, pre-existing concerns regarding the use of genetic engineering in crop production and skepticism about private sector involvement. The purpose of this case study was to understand the role of trust in the IRMA partnership by identifying the challenges to, and practices for, building trust in the project. Methods Data were collected by conducting face-to-face, semi-structured interviews; reviewing publicly available project documents; and direct observations. The data were analyzed to generate recurring and emergent themes on how trust is understood and built among the partners in the IRMA project and between the project and the community. Results Clear and continued communication with stakeholders is of paramount importance to building trust, especially regarding competition among partners about project management positions; a lack of clarity on ownership of intellectual property rights (IPRs; and the influence of anti-genetic modification (GM organizations. Awareness creation about IRMA’s anticipated products raised the end users’ expectations, which were unfulfilled due to failure to deliver Bacillus thuringiensis (Bt-based products, thereby leading to diminished trust between the project and the community. Conclusions Four key issues have been identified from the results of the study. First, the inability to deliver the intended products to the end user diminished stakeholders’ trust and interest in the project. Second, full and honest disclosure of information by partners when entering into project agreements is crucial to ensuring progress in a project. Third

    The tests of the prototype system indicated that the system is applicable for connecting pipeline bundle sections. The overall performance of the system is therefore concluded to be satisfactory. Some modifications are required though, for improving the reliability of the system to the level required for offshore North Sea application. The tests showed that connection of the pipeline bundle sections can be performed for alignment tolerances larger than those expected during a typical subsea installation. Pull-in of bundle end sections can be performed with pull-in wires deployed from surface. The offshore tests showed that handling of wires must be done with great care to avoid possibility for wire entanglement, especially if a fully diverless system is to be used. The flowline connection tool was found to be suitable for final alignment of the individual spool ends. It was demonstrated that face to face contact between the hub faces in the connector was obtained after tie-in. Pressure tests showed that the connector could be sealed by the tie-in force applied by the connection tool tie-in system. However, the standard connector clamp which was used, was found to be insuficient for maintaining the connector effectively sealed after removal of the pull-in force applied by the connection tool. Based on the results proposals for improvements of the system are included. Improvements are applicable to the current system for connection of bundle sections or for tie-in operations, relating to conventional pipelines. The improvements also includes a strong connection clamp suitable for subsea use. The connection clamp will replace the standard clamp devise used in this project. (au) EFP-96. 41 refs.

    The two broad categories of fiber-reinforced composite liner repair and deposited weld metal repair technologies were reviewed and evaluated for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without liners, indicating that this type of liner is generally ineffective at restoring the pressure containing capabilities of pipelines. Failure pressure for pipe repaired with carbon fiber-reinforced composite liner was greater than that of the un-repaired pipe section with damage, indicating that this type of liner is effective at restoring the pressure containing capability of pipe. Pipe repaired with weld deposition failed at pressures lower than that of un-repaired pipe in both the virgin and damaged conditions, indicating that this repair technology is less effective at restoring the pressure containing capability of pipe than a carbon fiber-reinforced liner repair. Physical testing indicates that carbon fiber-reinforced liner repair is the most promising technology evaluated to-date. Development of a comprehensive test plan for this process is recommended for use in the next phase of this project.

    The running condition of long distance water pipeline are complicated and changeable, and the lag of water flow is obvious, which is the key technical problem to be solved in the process of regulation and control. According to the present situation of the long-distance water conveyance project, the visualization simulation technology is used to study the operation and management of the long-distance water conveyance pipeline based on OpenGL technology. The system developed in this paper can combine pipeline information, working condition data and relevant data to provide a visualization platform for analysis and decision-making of project management and operation.

  10. Water quality regulation during construction of the trans-Alaska oil pipeline system

    Energy Technology Data Exchange (ETDEWEB)

    Zemansky, G.M.

    1983-01-01

    The trans-Alaska oil pipeline system (TAPS) was constructed by a consortium including some of the largest oil companies in the world. They had a strong economic incentive in rapid construction of the project, perceiving delay as equivalent to loss of large amounts of profit. State and federal governments had similarly compelling economic, political, and policy reasons to adopt this objective of the oil companies as their own. This dissertation is a retrospective assessment of water quality regulation during construction of the TAPS project (1974 through mid-1977). Its theoretical framework involves the degree to which regulatory redundancy (overlap) produced reliability in achieving compliance with water pollution control requirements. It was found during this research that noncompliance was widespread, frequent, and of a magnitude which was often large. The root cause of this unnecessary noncompliance was the overriding economic interest of the pipeline builders in rapid construction coupled with the failure of regulatory agencies to enforce. There was a greater appearance of regulatory redundancy than was actually the case. The same economic, political, and policy reasons that had led to TAPS project authorization and bureaucratic dynamics resulted in enforcement failure with regard to water pollution control requirements. Under a mandate to facilitate rapid construction, the regulatory agencies demonstrated an inability to accomplish any other objective at the same time. Common-mode failure largely defeated the beneficial potential of what limited regulatory redundancy there was. Additionally, meaningful public participation was prevented by lack of resources, lack of procedural opportunity, and resistance to it from industry and government. The dissertation is concluded with recommendations for improving regulatory performance through strengthened redundancy mechanisms.

  11. Pipeline coatings and joint protection: a brief history, conventional thinking and new technologies

    Buchanan, Robert [Canusa-CPS, Toronto, ON (Canada)

    2003-07-01

    Pipelines have been in use since oil was discovered and the need to move it efficiently from the well head to secondary transportation, refinery or market was first realized. Early pipelines were obviously crude, but corrosion was understood as being a problem which resulted in the need for corrosion preventive coatings. As coatings technology developed, pipeline coatings became better and longer lasting but also needed to advance as pipeline operating conditions became more severe. High performance pipeline coatings, such as the 3-layer polyethylene (3LPE) and, more recently, multi-layer polypropylene (MLPP), have been developed to meet the more demanding applications in today's market. Coatings are generally applied under well controlled factory conditions but weld joint systems need to be applied by contractors under unpredictable field conditions and yet provide performance and quality consistent with plant applied coatings. Polyethylene heat-shrinkable sleeves are the most commonly used corrosion protection system for field joints on 3LPE coated pipelines today due to their compatibility, ease of application, reliability and extensive track record. However, there has been an absence of a more universally accepted field joint solution for MLPP coated pipelines. This paper ultimately describes the evolution and development of the latest generation of heat-shrinkable sleeves for 3LPE plus a breakthrough technology in MLPP field joint coatings that has been tested, specified and successfully used in the field on many global projects by leading engineers and contractors, including in Brazil.

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

    2009-01-01

    Though Differential Ground Subsidence (DGS) impacts the seismic response of segmented buried pipelines augmenting their vulnerability, fragility formulations to estimate repair rates under such condition are not available in the literature. Physical models to estimate pipeline seismic damage considering other cases of permanent ground subsidence (e.g. faulting, tectonic uplift, liquefaction, and landslides) have been extensively reported, not being the case of DGS. The refinement of the study of two important phenomena in Mexico City - the 1985 Michoacan earthquake scenario and the sinking of the city due to ground subsidence - has contributed to the analysis of the interrelation of pipeline damage, ground motion intensity, and DGS; from the analysis of the 48-inch pipeline network of the Mexico City's Water System, fragility formulations for segmented buried pipeline systems for two DGS levels are proposed. The novel parameter PGV{sup 2}/PGA, being PGV peak ground velocity and PGA peak ground acceleration, has been used as seismic parameter in these formulations, since it has shown better correlation to pipeline damage than PGV alone according to previous studies. By comparing the proposed fragilities, it is concluded that a change in the DGS level (from Low-Medium to High) could increase the pipeline repair rates (number of repairs per kilometer) by factors ranging from 1.3 to 2.0; being the higher the seismic intensity the lower the factor.

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

    Full Text Available Hull construction process for a new shipbuilding project usualy consist of a set of stages. Starting from material identification, marking, cutting fabrication, assembly and testing. For many shipyard hull inspection activity and hull production stages are joined to simplify production progress monitoring. A 20% credit given for inspection activity. Inspection activities particulary for hull construction which consist of inspection and repair work. Schedule slip of a new shipbuilding is very potencial. This condition is met when man power allocation and work priority are not set properly. Therefore, a clear parameter which conduct with inspection productivity to production manager should be provided. This parameter could help production manager to determine priority of repair work. In this case, differences parameter between production that is using pane measurement and inspection that is using compartement measurement. These two different parameter could make difficulties, particulary when production manager want to know how much progess has been done. A new method to converting the two different parameter has become a topic of this paper

    Full Text Available Problem statement: Public participation has become a vital element of environmental decision-making. Although public participation has grown tremendously in Thailand due to a rising pressure from the public, this practice often fails to solve environmental problems and conflicts. There is a keen for a systematic evaluation of the public participation process to investigate whether the participation process is effective and what works or does not work in this respect. Approach: This study evaluates the effectiveness of the public participation process of the Hin Krut power plant project through an evaluation model developed from relevant literatures. Results: It was found that the public participation process of the case study was not completely effective when tested against the evaluation criteria. The affected people had no chance to present any comments at the very beginning. The public participation process started too late, after a decision had been made and conflicts among stakeholders already occurred. Conclusion: The public participation process is not yet properly established in the Thai context. There is an urgent need to find a working model and conditions of public participation which can assist in resolving environmental problems. Finally, a set of recommendations for improving public participation process are suggested.

    Dengue fever is one of the most serious vector-borne infectious diseases, especially in Guangzhou, China. Dengue viruses and their vectors Aedes albopictus are sensitive to climate change primarily in relation to weather factors. Previous research has mainly focused on identifying the relationship between climate factors and dengue cases, or developing dengue case models with some non-climate factors. However, there has been little research addressing the modeling and projection of dengue cases only from the perspective of climate change. This study considered this topic using long time series data (1998-2014). First, sensitive weather factors were identified through meta-analysis that included literature review screening, lagged analysis, and collinear analysis. Then, key factors that included monthly average temperature at a lag of two months, and monthly average relative humidity and monthly average precipitation at lags of three months were determined. Second, time series Poisson analysis was used with the generalized additive model approach to develop a dengue model based on key weather factors for January 1998 to December 2012. Data from January 2013 to July 2014 were used to validate that the model was reliable and reasonable. Finally, future weather data (January 2020 to December 2070) were input into the model to project the occurrence of dengue cases under different climate scenarios (RCP 2.6 and RCP 8.5). Longer time series analysis and scientifically selected weather variables were used to develop a dengue model to ensure reliability. The projections suggested that seasonal disease control (especially in summer and fall) and mitigation of greenhouse gas emissions could help reduce the incidence of dengue fever. The results of this study hope to provide a scientifically theoretical basis for the prevention and control of dengue fever in Guangzhou. Copyright © 2017 Elsevier B.V. All rights reserved.

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

    Scour depth prediction of offshore pipelines is of great significance to the design and construction of the submarine pipeline projects. In this paper, based on the CFD software package FLUENT and User Defined Function (UDF), an Eulerian two-phase model, which includes an Euler-Euler coupled model for water and sediment phases, and a turbulent model for the fluid phase, is adopted to predict the scour depth around pipelines. The model is verified by observation data obtained from laboratory experiments. On the basis of the simulations, the factors affecting the scour depth, including the effects of incipient velocity, pipe diameter and sediment particle size and so on, were investigated. Meanwhile, according to formulas of incipient velocity of various sediments, approximate calculation on theoretical scour depths is developed for pipelines of seven stations in the South China Sea, where engineering application information is available.

    The Ultramonit unit is a clamp-on tool (removable) that uses an array of sensors to provide online, real-time, reliable and repeatable high accuracy ultrasonic wall thickness measurements and corrosion monitoring at selected locations along the pipeline. The unit can be installed on new or existing pipelines by diver or ROV. The system is based on the well-established ultrasonic pulse-echo method (A-scan). Special processing methods, and the fact that the unit is fixed to the pipeline, enable detection of changes in wall thickness in the micro-meter range. By utilizing this kind of resolution, it is possible to project corrosion rates in hours or days. The tool is used for calibration of corrosion inhibitor programs, verification and calibration of inspection pig data and general corrosion monitoring of new and existing pipelines. (author)

    We present the data reduction pipeline for the Hi-GAL survey. Hi-GAL is a key project of the Herschel satellite which is mapping the inner part of the Galactic plane (|l| <= 70\\cdot and |b| <= 1\\cdot), using 2 PACS and 3 SPIRE frequency bands, from 70{\\mu}m to 500{\\mu}m. Our pipeline relies only partially on the Herschel Interactive Standard Environment (HIPE) and features several newly developed routines to perform data reduction, including accurate data culling, noise estimation and minimum variance map-making, the latter performed with the ROMAGAL algorithm, a deep modification of the ROMA code already tested on cosmological surveys. We discuss in depth the properties of the Hi-GAL Science Demonstration Phase (SDP) data.

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

    The Cactus-San Fernando gas pipeline system is 650 km in length and was constructed in the late 1970s. The system transports more than 1100 million standard cubic feet per day of dry natural gas to electricity generators in Mexico. This paper described a project undertaken to re-validate the pipeline and demonstrate the future integrity of the pipeline system and ensure that it was suitable for operation to 1219 psig. Pipeline sections were inspected using high resolution magnetic flux leakage (MFL) in-line inspection (ILI) tools, and inertial mapping unit vehicles equipped with global positioning surveys (GPS). The combined inspections allowed the project team to accurately identify features of the pipeline that required repairs. External and internal corrosion were identified as the most prevalent defects. RSTRENG methodologies were used to investigate the interaction of individual corrosion anomalies. Corrosion patterns were compared, and above-ground survey data were used to establish the causes of both the external and internal corrosion, as well as to establish future corrosion growth rates. Decision tree analysis was then used to analyze the growth rates and to identify statistical differences between corrosion growth rates as a function of distance along the pipeline. After the ILI reports were generated, an integrity assessment was then conducted to identify necessary repair options. Repairs plans were then developed along with recommended re-inspection intervals for each section. After the integrity assessments were accepted by a certification company, field work was conducted to locate and measure defects. Defects characteristic of major volumetric welding flaws introduced during pipeline construction were identified and repaired with an epoxy sleeve technique. It was concluded that repairs needed to operate the pipeline at the requested pressure were accomplished within a period of 8 months. 7 refs., 2 tabs., 4 figs.

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

  12. Joint implementation initiatives in South Africa: A case study of two energy-efficiency projects

    Energy Technology Data Exchange (ETDEWEB)

    Van Horen, C.; Simmonds, G.; Parker, G.

    1998-11-01

    This paper explores the issues pertinent to Joint Implementation (JI) in South Africa by examining two prototype potential projects on energy efficiency with the potential for reducing greenhouse gas (GHG) emissions. The first is an energy-efficient lighting project based on the public electricity utility, Eskom's plan for a compact fluorescent lighting program in the residential sector. The analysis indicates that the CFL program could avoid emissions of up to 243 thousand tons of carbon over the first five years, at negative cost (that is, with a positive economic return). The second project involves the delivery of passive solar, energy-efficient housing to a low-income township in the Western Cape Province, at an incremental capital cost of approximately $2.5m for the 6000 houses. In this case, the avoided GHG emissions over the first five years amount to between 14 and 20 tons of carbon, and over the 50 year life-span of the project it will result to 140 to 200 thousand tons of avoided emissions at a cost of $13 to $17 per ton. The housing project has significant non-GHG benefits such as savings on energy bills and health, which accrue to the low-income dwellers. A number of important JI-specific issues and concerns emerge with respect to the two projects, which can also be applied to other potential JI opportunities in the country generally. These include the issues of carbon credit sharing, for which a number of scenarios are suggested, as well as estimating unknown macroeconomic impacts, such as the effects of CFLs on the country's incandescent lighting industry. Findings from an examination of both potential projects conclude that capacity-building within the country is critical to ensure that the technology being transferred balances efficiency, cost and quality appropriate to the South African context. Finally, assessment and evaluation, monitoring and verification criteria and institutions are called for to guarantee measurable long

    Full Text Available Abstract Introduction Sustainable service delivery is a major challenge in the HIV response that is often not adequately addressed in project implementation. Sustainable strategies must be built into project design and implementation to enable HIV efforts to continue long after donor-supported projects are completed. Case description This paper presents the experiences in operational sustainability of Family Health International's Zambia Prevention, Care and Treatment Partnership in Zambia, which is supported by the US President's Emergency Plan for AIDS Relief through United States Agency for International Development (October 2004 to September 2009. The partnership worked with Zambia's Ministry of Health to scale up HIV clinical services in five of the country's nine provinces, reaching 35 districts and 219 facilities. It provided technical and financial support from within the ministry's systems and structures. By completion of the project, 10 of the 35 districts had graduated beyond receiving ongoing technical support. Discussion and evaluation By working within the ministry's policies, structures and systems, the partnership was able to increase the ministry's capacity to add a comprehensive HIV service delivery component to its health services. Ministry structures were improved through renovations of health facilities, training of healthcare workers, procurement of essential equipment, and establishment of a quality assurance plan to ensure continued quality of care. The quality assurance tools were implemented by both the ministry and project staff as the foundation for technical graduation. Facilities that met all the quality criteria for more than six months were graduated from project technical support, as were districts where most supported facilities met the criteria. The district health offices then provided ongoing supervision of services. This predetermined "graduation" exit strategy, with buy in of the provincial and district

    Full Text Available This paper presents a case study examining 3rd, 4th and 5th graders’ design fixation and cooperative learning in an engineering design project. A mixed methods instrument, the Cooperative Learning Observation Protocol (CLOP, was adapted to record frequency and class observation on cooperative learning engagement through detailed field notes. Students’ design journals and reflections were also analyzed for an inductive qualitative analysis. The findings indicate three major themes of design fixation: 1 fixation on common features of things; 2 fixation on popular teenage culture; 3 fixation on the first design idea. In the cooperative learning process of elementary engineering design project, although pupils had demonstrated some abilities to solve concrete problems in a logical fashion, the participants encountered a number of obstacles in the group. Dominance, social loafing, and other problems occurring in the group process might have offset certain benefits of cooperative learning. Implications of the findings are also discussed.

    Large sensor-based science infrastructures for radio astronomy like the SKA will be among the most intensive datadriven projects in the world, facing very high demanding computation, storage, management, and above all power demands. The geographically wide distribution of the SKA and its associated processing requirements in the form of tailored High Performance Computing (HPC) facilities, require a Greener approach towards the Information and Communications Technologies (ICT) adopted for the data processing to enable operational compliance to potentially strict power budgets. Addressing the reduction of electricity costs, improve system power monitoring and the generation and management of electricity at system level is paramount to avoid future inefficiencies and higher costs and enable fulfillments of Key Science Cases. Here we outline major characteristics and innovation approaches to address power efficiency and long-term power sustainability for radio astronomy projects, focusing on Green ICT for science and Smart power monitoring and control.

    Full Text Available Completing strategic Information Technology (IT projects as planned is certainly an important objective for large firms. One of the measures adopted to reach this goal systematically is to create a Project Management Office in the IT area (PMO-IT. However, many firms consider the possibility of creating a PMO-IT, but decide not to do it. This paper presents the results of an exploratory research about the contextual drivers that determine the decision to create PMO-Its. Through two case studies of large Brazilian firms – one that created the entity and another which believes does not need it –, the drivers of the decision to create or not to create a PMO-IT were identified, and it was possible to confirm some of the drivers mentioned in the literature. This paper increases the undertstanding about this topic, which is important in the Management Information Systems field, as well as indicates paths for future research.

    Against the backdrop of global oil industry trends and the specificity of the Brazilian energy sector, this study evaluates whether the option to develop a national market linked with a plan to export liquefied natural gas produced in Brazil is financially advantageous relative to the traditional pipeline alternative for the aim of satisfying the current natural gas deficit in the Northeast region. To this end, this dissertation analyses the economic conditions for Brazilian LNG in the international gas market, mainly for European and North-American gas markets. Employing a probabilistic analysis based on the Monte Carlo method and given the premises adopted and the amount of information available at the time of writing, the study concludes that, while the international LNG market has enjoyed vigorous growth in recent years, the option of using it as a strategy to develop local market is a less attractive investment choice compared with the pipeline alternative.
