    1985-02-01

    Imported LNG is temporarily stored in tanks at base-load plants. Because of the large quantities involved and the potential hazards associated with an accident spill, federal, state, and local governmental agencies have adopted stringent safety regulations for siting, design, construction, and operation of these facilities. Acceptance of a proposed LNG site by regulatory agencies is influenced by the risk levels associated with earthquakes, landslides, floods, winds, tornadoes and tsunamis. It is the responsibility of the project sponsor to investigate the geological and seismic conditions, population density and other requirements.

  2. Seismological investigations for siting an LNG facility

    Energy Technology Data Exchange (ETDEWEB)

    1985-05-01

    Siting of Liquefied Natural Gas (LNG) facilities requires seismological investigations to identify the closest capable faults, to estimate the capability of faults in the vicinity of proposed sites to generate earthquakes, and to provide engineers with appropriate ground-motion parameters (peak acceleration, predominant period, and duration of strong ground-motion) for design and construction. These investigations consist of analysis of seismicity data to correlate hypocenters and faults, estimation of the maximum magnitude of an earthquake for particular faults, and calculations of recurrence intervals of earthquakes. The investigation of the proposed Little Cojo Bay LNG Terminal Site, near Point Conception, California, for which a peak acceleration of about 0.65 g appears reasonable, is presented as an example.

  4. The role of consequence modeling in LNG facility siting.

    Science.gov (United States)

    Taylor, Dennis W

    2007-04-11

    Liquefied natural gas (LNG) project modeling focuses on two primary issues, facility siting and the physical layout of element spacing. Modeling often begins with an analysis of these issues, while ensuring code compliance and sound engineering practice. The most commonly performed analysis involves verifying compliance with the siting provisions of NFPA 59A, which primarily concern property-line spacing (offsite hazard impacts). If the facility is located in the US, compliance with 49 CFR 193 is also required. Other consequence modeling is often performed to determine the spacing of elements within the facility (onsite hazard impacts). Often, many issues concerning in-plant spacing are addressed with the guidance provided in Europe's LNG standard, EN-1473. Spacing of plant buildings in relation to process areas is also a concern as analyzed using the approach given in API RP 752. Studies may also include probabilistic analysis, depending on the perceived risk and cost of mitigation.

  5. How to protect underground water flowing into Fukushima Nuclear Facility. Using by heat pipes and LNG

    International Nuclear Information System (INIS)

    We invented an innovative artificial permafrost forming method to prevent the flowing of under-ground water into Fukushima nuclear facility. In this proposal, heat pipes are embedded at all around of the nuclear facility to cool the hygroscopic soil effectively, and LNG is used as both a cold source and the fuel of 1,000,000,000W gas-turbine electric generator. We calculated artificial permafrost wall forming by transient calculation at several condition, and we also calculated maximum amount of heat transport of heat pipe. Based on the result, we confirmed that this proposal have a good feasibility. Finally, we estimated the total cost of this proposal. (author)

    LNG storage facilities are indispensable to satisfy demand throughout the year by saturating the time difference of supply and demand that appears due to seasonal factors. The necessity of storage facilities is more important in a country like Korea where LNG is not produced at all and imports are relied upon. The problem of deciding how much storage facilities to keep and in what pattern to import LNG is a question to solve in order to minimize the costs related to the construction of LNG storage facilities while not causing any problem in the supply and demand of LNG. This study analyzes how the import of LNG and the consumption pattern of LNG for power generation affect the decision on the size of storage facilities. How the shipping control, and how LNG demand for power generation affect the decision of requirement of storage facilities, and why the possibility of shipping control should be investigated in the aspect of costs is investigated. As a result of this study, I presented necessary basic data for drafting a policy by assessing the minimum requirements of storage facilities needed for balancing the supply and demand with the various shipping control and LNG consumption patterns through simulation up to the year 2010. 10 refs., 33 figs., 66 tabs.

  11. North America and Asia Pacific LNG markets

    International Nuclear Information System (INIS)

    The liquefied natural gas (LNG) export opportunities in the Asia Pacific market were reviewed. Some of the differences that affect a North American LNG projects compared to more typical LNG projects were also outlined. The two main aspects of the LNG market in North America include the establishment of LNG import terminals on the east and southern coasts of the United States and the development of export oriented LNG projects. The Pac-Rim LNG project calls for initial delivery to South Korea of 4.0 MTPA by the end of 2000. A large LNG project has also been proposed for the year 2005 which would use Prudhoe Bay gas. Generally, in North America, there is little use for large scale LNG import projects because of the vast pipeline network that delivers gas reliably and at low cost anywhere in North America. However, LNG remains a good alternative for the Asia Pacific region because of the lack of a pipeline network. Also, Japan, Korea and Taiwan, the three main centers for LNG demand, have no domestic energy supplies and rely on imported energy sources. China is another major market opportunity for LNG. The Pac-Rim LNG project differs from others of its kind in that usually, an LNG project is based on the availability of large reservoirs of natural gas owned by state governments and involves production agreements with multi-national oil and gas companies. This scenario is simply not possible in Canada's deregulated environment. In contrast, the existence of upstream facilities, technical expertise, and low capital costs, hence reduced risks and time to develop an LNG project, gives Canada significant advantages. 3 tabs., 3 figs

  15. Consensual decision-making model based on game theory for LNG processes

    International Nuclear Information System (INIS)

    Highlights: ► A Decision Making (DM) approach for LNG projects based on game theory is presented. ► DM framework was tested with two different cases, using analytical models and a simple LNG process. ► The problems were solved by using a Genetic Algorithm (GA) binary coding and Nash-GA. ► Integrated models from the design and optimization of the process could result in more realistic outcome. ► The major challenge in such a framework is related to the uncertainties in the market models. - Abstract: Decision-Making (DM) in LNG projects is a quite complex process due to the number of actors, approval phases, large investments and capital return in the long time. Furthermore, due to the very high investment of a LNG project, a detailed and efficient DM process is required in order to minimize risks. In this work a Decision-Making (DM) approach for LNG projects is presented. The approach is based on a consensus algorithm to address the consensus output over a common value using cost functions within a framework based on game theory. The DM framework was tested with two different cases. The first case was used for evaluating the performance of the framework with analytical models, while the second case corresponds to a simple LNG process. The problems were solved by using a Genetic Algorithm (GA) binary coding and Nash-GA. The results of the DM framework in the LNG project indicate that considering an integrated DM model and including the markets role from the design and optimization of the process more realistic outcome could be obtained. However, the major challenge in such a framework is related to the uncertainties in the market models.

    The design, engineering and operation of LNG base load liquefaction and re-gasification facilities is now considered a mature technology. However, process efficiency at these plants is limited by fundamental thermodynamic principles and no radical technology breakthroughs are expected in the near future. Three important aspects affecting the cost of production are the molecular weight of the gas, the amount of nitrogen in the feed and the acid gas composition. Variations in composition will also affect the design of the facilities and production rate. Previous projects have optimised economies of scale, using processes based on large industrial gas turbines, to achieve the minimum unit cost for LNG production. LNG producers have continued to focus on larger train designs to further capitalize on economies of scale as well as continued expansion of existing facilities. The latest plant designs expect the optimum integration with existing facilities to be a major factor in optimising specific capital costs. Whilst design codes and standards have not been discussed in many papers on LNG cost reduction, it is generally accepted that project specifications can significantly impact the project cost. The cost of equipment can be significantly inflated by onerous specifications with non standard requirements that vendors have trouble meeting. The possibility of developing gas projects will mainly be determined by the requirements of power generation and/or the industrial sector. As far as power generation is concerned, expansion will rely greatly on combined cycle plants. The competitiveness of LNG as regards power generation can be further improved by adopting integrated solutions. As in all other industrial projects, one of the first concerns for the investor when he envisages building an LNG liquefaction or re-gasification terminal is the selection of the site where the terminal will be located.

    Germany needs an LNG receiving terminal to import LNG and supplement expected future gas supply shortages. Enormous economic benefits also abound if Germany is to install an LNG receiving terminal. Jobs will be created for several hundred people. New tax revenues will be generated for state and local governments and this will further enhance the economic competitiveness of Germany. Additionally, it will provide Germany with a reliable source of clean-burning energy. Any proposed LNG receiving terminal should incorporate safety right from the start. These safety requirements will: ensure that certain public land uses, people, and structures outside the LNG facility boundaries are protected in the event of LNG fire, prevent vapour clouds associated with an LNG spill from reaching a property line that can be built upon, prevent severe burns resulting from thermal radiation, specify requirements for design, construction and use of LNG facilities and other equipments, and promote safe, secure and reliable LNG operations. The German future LNG business will not be complete without the evolution of both local and international standards that can apply to LNG operations. Currently existing European standards also appear inadequate. With an OHSAS 18001 management system integrated with other existing standards we can better control our LNG occupational health and safety risks, and improve performance in the process. Additionally, an OHSAS 18001 System will help future German LNG contractors and operators safeguard their most important assets - their employees. (orig.)

The spot and short-term imports (based on importing contracts whose duration is equal to or less than 4 years) amounted to 56 106 m3 in liquid form (438 cargoes) as against 40 106 m3 (348 cargoes) in 2005, accounting for 16% of the world LNG trade. Tanker fleet: The world LNG tanker fleet consisted of 219 vessels at the end of 2006. Five of these, delivered in 2006, the Excelerate, the Seri Angkasa, the Seri Anggun, the LNG Lokoya and the Gaz de France Energy, did not unload any cargo during the year. Liquefaction plants: There were 18 sites of liquefaction plants in operation at the end of 2006 with the start-up of the Darwin LNG plant in Australia. Two new trains were commissioned in 2006: one at Bonny Island in Nigeria and one at Darwin in Australia. The total capacity of all liquefaction plants amounted to about 413 106 m3 of LNG per year, or 188 106 t for 78 liquefaction trains. Considering a total production of 348.4 106 m3 of LNG, the average utilization almost reached 85%. The total storage capacity amounted to approximately 6 106 m3 of LNG for 66 storage tanks, representing almost six days of production. Re-gasification plants: There were 57 re-gasification plants in the world. Six terminals went on stream in 2006: Sagunto in Spain, Aliaga in Turkey (completed in 2002), Altamira in Mexico, Guangdong Dapeng in China and Mizushima and Sakai in Japan. The total send-out capacity of the facilities in operation amounted to 516 billion Nm3 NG/year and their storage capacity to 25.8 106 m3 of LNG with 283 storage tanks

    Kitimat LNG terminal is the first fully permitted liquefied natural gas (LNG) on the west coast of Canada and the United States. The terminal was designed to have a small environmental footprint, and has the full support of communities and First Nations groups in the area. Regulatory approvals are now in place, and site construction is planned to start in 2007. This presentation provided details of the facility's gas production and liquefaction processes, shipping, and LNG import and regasification terminals. The site was selected due to its deepwater, all-season port and the fact that the Pacific Trail Pipelines provide access to major transmission lines. The terminal will be comprised of an offshore LNG tanker berth and unloading jetty, a construction and tug berth, 2 LNG storage tanks, a separation unit, and send-out pipelines for natural gas and gas liquids. The terminal was designed for maximum LNG receiving flexibility as it can handle a wide variety of gas specifications and will be able to receive the largest possible LNG tankers. Market interest in the terminal has been considerable as investors are increasingly convinced that LNG can provide long-term supply alternatives to the North American gas market. Once operational the terminal will attract supply from the Pacific basin and the Middle East. Western Canadian gas demand is projected to grow at nearly 6 per cent through 2015. It was concluded that marine safety is crucial to the successful operation of the terminal. Details of safety plans formed after consultation with various organizations were presented. refs., tabs., figs.

    This cooperative research project validates use of man made salt caverns to receive and store the cargoes of LNG ships in lieu of large liquid LNG tanks. Salt caverns will not tolerate direct injection of LNG because it is a cryogenic liquid, too cold for contact with salt. This research confirmed the technical processes and the economic benefits of pressuring the LNG up to dense phase, warming it to salt compatible temperatures and then directly injecting the dense phase gas into salt caverns for storage. The use of salt caverns to store natural gas sourced from LNG imports, particularly when located offshore, provides a highly secure, large scale and lower cost import facility as an alternative to tank based LNG import terminals. This design can unload a ship in the same time as unloading at a tank based terminal. The Strategic Petroleum Reserve uses man made salt caverns to securely store large quantities of crude oil. Similarly, this project describes a novel application of salt cavern gas storage technologies used for the first time in conjunction with LNG receiving. The energy industry uses man made salt caverns to store an array of gases and liquids but has never used man made salt caverns directly in the importation of LNG. This project has adapted and expanded the field of salt cavern storage technology and combined it with novel equipment and processes to accommodate LNG importation. The salt cavern based LNG receiving terminal described in the project can be located onshore or offshore, but the focus of the design and cost estimates has been on an offshore location, away from congested channels and ports. The salt cavern based terminal can provide large volumes of gas storage, high deliverability from storage, and is simplified in operation compared to tank based LNG terminals. Phase I of this project included mathematical modeling that proved a salt cavern based receiving terminal could be built at lower capital cost, and would have significantly higher

  9. The Japanese approach to financing LNG projects

    International Nuclear Information System (INIS)

    The Japanese approach approach to financing LNG project has been what could be called a combined purchase and finance system which has been arranged mainly at the initiative of japan's Sogo Shosh (general trading companies) with the support of japanese governmental financial agencies and a purchase commitment from japanese utilities. In the QATARGAS project, despite it being the first greenfield LNG project in decade since North West Shelf Australia LNG project, financing for the LNG plant phase has been successfully arranged through Japanese financing. The structuring of the financial facilities for the QATARGAS project seems to have lessons for future development of the next generation of greenfield LNG projects. Discharge of the parties' liability, proper sharing of the risk burden and reconfirmation of the spirit of mutual understanding and trust among the parties concerned are key factors for the success of any new LNG project in the future.

  10. Hazard identification for innovative LNG regasification technologies

    International Nuclear Information System (INIS)

    Emerging risks may arise from process intensification and new scenarios due to the innovative technologies and higher potentialities of new LNG regasification facilities. In the conventional hazard identification process it is difficult to include new scenarios related to innovative technologies or facilities, for which limited or no operational experience is available. In the present study, a new technique for HAZard IDentification (HAZID), named Dynamic Procedure for Atypical Scenarios Identification (DyPASI), was applied to identify atypical accident scenarios in LNG terminals. The technique aims to make easier and more systematic the process of learning from early warnings and identify atypical accident scenarios otherwise disregarded by common HAZID techniques. The comparison with a survey of the accident scenarios typically considered in available Environmental Impact Assessment (EIA) studies evidences that DyPASI is a valuable tool to obtain a complete and updated overview of potential hazards in particular for new or innovative technologies, where limited operational experience is available. - Highlights: • New accident scenarios related to innovative technologies are difficult to identify. • DyPASI allowed identifying LNG-specific scenarios disregarded by other techniques. • The analysis was based on the systematization of data from past events and studies. • These scenarios were partially overlooked by the Environmental Impact Assessments. • Emerging technologies may be inclined to atypical accident scenarios

  11. The LNG Industry - 2013

    International Nuclear Information System (INIS)

    In 2013 the LNG markets remained extremely tight due to the demand pull from nuclear closures in Japan and South Korea and the difficulties to ramp-up production of new facilities in Angola and Algeria, bringing LNG price levels in the Far East to record highs in the first quarter. In addition to Cheniere's Sabine Pass, three new liquefaction projects received full approvals in the U.S.A. last year, confirming the country's path to become the world's third largest LNG exporter by the end of the decade. Cameron joined their ranks in early 2014 so that at the time of this writing, a total 62.5 Mt/y of capacity have been approved to export to non-FTA countries by the Department of Energy, already impacting the LNG industry, if not in physical volume then in contracting strategy. 2013 could be considered a transition year. LNG traded volumes as a whole remained at the same level as in 2012, but new trade patterns seem to emerge. The past year may have seen a slowdown in the number of FIDs, counting only one greenfield (Yamal LNG) and two expansion projects, but not in capacity increase with a respectable 29 Mt/y committed in total. Demand remained strong in Asia, mainly in China and South Korea. In Japan, imports continued to increase, although more moderately in a response to high prices and the yen devaluation, shifting the energy mix towards other sources of energy. Demand also increased in South America, strongly related to weather factors. Europe remained the swing provider to the world's LNG market. In a context of depressed local demand and with the utilization rate of the re-gasification terminals in their region at a historical low, European players continued with innovative transactions in search for business (such as re-loadings, two-port loadings, ship-to-ship transfers) while developing new markets for LNG as a transportation fuel. Three new countries joined the ranks of LNG importers in 2013: Israel, Malaysia, and Singapore. Total

    To enhance the energy efficiency in the liquefied natural gas (LNG) vehicles, thermoelectric generator (TEG) is suggested in recovering the waste heat of the exhaust gas (EG) and the cold energy of the LNG.The TEGs here get higher efficiency than conventional ones, for they work with heat sinks at cryogenic temperatures and there are large temperature differences between EG and LNG.Based on the analyzing of the typical fuel system in the small LNG vehicles, two recovery systems for the LNG vehicles are proposed and the correla_tive parameters of systems are calculated and analyzed.The generation efficiency of TEGs is calculated and the recovery power of each sys_tem is analyzed.It is concluded that the output power of the vaporizer system is larger than that of the self_warming system; TEG with opti_mized multi_layer material brings larger output power than that with single_layer material for both systems.%为实现液化天然气(LNG)汽车的节能,提出了利用温差发电器(TEG)回收发动机排气(EG)的废热和低温燃料的冷能。指出了基于冷源所在的低温区,以及 EG 与 LNG 之间的大温差这两个特点,TEG 的热电转换效率会高于常规。基于对小型 LNG汽车中典型燃料系统的分析,设计了进行能量回收的两种系统流程,计算了其中各状态点的参数﹑及各换热器中布置温差发电器后的热电转换效率,得到了系统总的回收功率。结果表明,汽化器系统的回收功率大于自复温系统;在两种系统中,合理选取多种材料相较于仅用单种材料,TEG 的回收功率更大。

    Onshore LNG receiving terminal is an important facility in offshore LNG import system. According to the growing human accidents of LNG receiving terminals in China at present, based on the HFACS analysis of accident causation model which had been used in the aviation accident investigation, the impact factors of human accidents were divided into five categories, which contain personal factors, group factors, environmental factors, supervision and organizational factors, and the human accidents identification method of LNG receiving terminal was obtained based on grey relational analysis of gray theory. Finally, the method was applied to identify the accidents happened in an LNG receiving terminal, and it was found that the main insecurity events were "the una-wareness of security" in "personal factors" by calculating the grey relational grade. This method overcomes the disadvantage due to the small sample of accident data, which has certain guiding sense to safeguard the safety operation of LNG receiving terminals.%陆岸LNG接收终端是LNG海上进口系统中的重要设施.针对我国LNG接收终端人因事故不断增多的现状,基于航空事故调查分析中的HFACS事故致因分析模型,将人因事故的影响因素归纳为个人因素、人际因素、环境因素、监督因素和组织因素五大类,结合灰色理论中的灰色关联分析,得到了LNG接收终端人因事故辨识方法.最后,运用该方法对某LNG接收终端人因事故进行辨识,通过灰关联度的计算,找出其最主要的不安全事件来自“个人因素”中的个人“安全意识不强”.此方法克服了小样本事故数据带来的弊端,对保障LNG接收终端的安全运行具有一定的指导意义.

  14. LNG in transportation

    International Nuclear Information System (INIS)

    This document summarizes the content of a 402 p. study published by CEDIGAZ, the International Center for Natural Gas Information. According to this study, LNG as a fuel will capture a significant market share in the transport sector by 2035. The greatest potential is seen in road transport, were annual demand is projected to reach 96 million tons per year (mtpa) in CEDIGAZ' base scenario while demand in the marine sector could grow to an estimated 77 mtpa. The rail sector could add another 6 mtpa to global demand. However, the development of LNG as a transport fuel faces a number of challenges, and will have to go hand in hand with the development of fueling infrastructure

    While recognized standards exist for the systematic safety analysis of potential spills or releases from LNG (Liquefied Natural Gas) storage terminals and facilities on land, no equivalent set of standards or guidance exists for the evaluation of the safety or consequences from LNG spills over water. Heightened security awareness and energy surety issues have increased industry's and the public's attention to these activities. The report reviews several existing studies of LNG spills with respect to their assumptions, inputs, models, and experimental data. Based on this review and further analysis, the report provides guidance on the appropriateness of models, assumptions, and risk management to address public safety and property relative to a potential LNG spill over water.

    The conversion potential to replace oil in the energy intensive industries and diesel in heavy transport is estimated in the study to 6.8 TWh and 10 TWh per year, respectively. Several alternative fuels compete for this conversion potential. What fuels will take market share depends on several factors such as price, availability of fuel, availability of process technology and vehicles, technology development and possible future technological advances. For liquid methane to compete a new infrastructure is required that in a cost effective manner makes it possible to distribute the liquid methane to the regions where the need is the greatest. With today's distribution system, including truck delivery from import terminals in Nynaeshamn and Fredrikstad, virtually the entire southern Sweden is within reach of LNG deliveries. The study points out three nodes, Gaevle, Sundsvall and Luleaa, which is suitable for distribution of liquid methane to the central and northern Sweden. The three hubs are suitable for freight transfer to trucks as well as rail and shipping. A strategic nationwide network of refueling stations is also proposed, with a total of 18 new stations, in addition to the filling stations in southern and central Sweden that are already planned or in operation. Both the availability and use of liquid methane in Sweden today is limited. Liquid natural gas, LNG (liquefied natural gas), is primarily used as a backup to biogas plants, in a few industries and as supply for a few filling stations for compressed gas. The availability of LNG and also liquid biogas (LBG liquefied biogas), will increase in coming years. In 2011, two new LNG import terminals are put into operation in Nynaeshamn and Fredrikstad in Norway and two additional import terminals are planned in Gothenburg and Lysekil. Furthermore, two production plants for liquid biogas production have started, and four additional plants are planned, which together will produce around 0.5 TWh LBG annually

    The US Department of Energy (DOE) is conducting research on the safety and other environmental aspects of liquefied energy gases including liquefied natural gas (LNG). The effort reported here was conducted as part of the planning for further research into the safety aspects of transporting and storing LNG, with primary emphasis on public safety. Although the modern LNG industry has enjoyed excellent success in providing for safe operations, significant questions remain on the part of many, the expressions of which were intensified with the addition of marine-based LNG import terminals. Public safety with regard to large-scale importation of this fuel has received widespread attention in the US Congress, state legislatures, county and city governments, and from various individuals and public groups, with coverage in all the news media, including books published on the subject. The safety concerns have centered around the consequences to the public of a large spill of the cryogenic liquid from an ocean tanker or a larger storage tank, either of which might hold as much as 125,000 m/sup 3/ of LNG.

    This cooperative research project validates use of man made salt caverns to receive and store the cargoes of LNG ships in lieu of large liquid LNG tanks. Salt caverns will not tolerate direct injection of LNG because it is a cryogenic liquid, too cold for contact with salt. This research confirmed the technical processes and the economic benefits of pressuring the LNG up to dense phase, warming it to salt compatible temperatures and then directly injecting the dense phase gas into salt caverns for storage. The use of salt caverns to store natural gas sourced from LNG imports, particularly when located offshore, provides a highly secure, large scale and lower cost import facility as an alternative to tank based LNG import terminals. This design can unload a ship in the same time as unloading at a tank based terminal. The Strategic Petroleum Reserve uses man made salt caverns to securely store large quantities of crude oil. Similarly, this project describes a novel application of salt cavern gas storage technologies used for the first time in conjunction with LNG receiving. The energy industry uses man made salt caverns to store an array of gases and liquids but has never used man made salt caverns directly in the importation of LNG. This project has adapted and expanded the field of salt cavern storage technology and combined it with novel equipment and processes to accommodate LNG importation. The salt cavern based LNG receiving terminal described in the project can be located onshore or offshore, but the focus of the design and cost estimates has been on an offshore location, away from congested channels and ports. The salt cavern based terminal can provide large volumes of gas storage, high deliverability from storage, and is simplified in operation compared to tank based LNG terminals. Phase I of this project included mathematical modeling that proved a salt cavern based receiving terminal could be built at lower capital cost, and would have significantly higher

  1. The LNG Industry - 2012

    International Nuclear Information System (INIS)

    noteworthy that Europe makes up more than three quarters of these reloads, nearly all attributable to Spain and Belgium, two of the countries in Europe with sufficient firm destination supplies to sustain regular reloads. The hotly debated US LNG exports on the other hand are to be viewed as a far more important trend with profound commercial consequences, assuming that last year's pioneering FID by Cheniere will have several followers in 2013. At the time of this writing however none of the twenty or so projects somewhere 'in the pipeline' in the USA and Canada have reached this final stage yet. The commercial pricing principles will be groundbreaking if the Cheniere project is followed by other projects, eagerly awaited by many Asian importers, hoping that Henry Hub-based pricing can bring relief from crude price indexing in the future. The outlook for LNG demand remains strong, particularly in Asia and in the new markets of Latin America and the Middle East. Unless there is a rapid and sizeable restart of nuclear capacity in Japan- generally not regarded as likely- LNG markets are expected to remain tight until 2015, when a wave of new production is to come on-stream. Over the next two to three years as little as 20 million tons p.a. of new capacity ( a mere 8% addition ) are likely to start up and redirections from the Atlantic Basin of flexible cargoes would continue to balance demand In Asia. In the second part of the decade and beyond, a wave of new projects, many already under construction in Australia, as well as possibly in North America and from the promising East African discoveries should satisfy market demand growth and sustain the confidence in LNG thriving industry

The report includes a discussion of possible human error contributions to previous LNG accidents and incidents, and a discussion of generic HF considerations for peakshaving plants. More specific recommendations for improving HF practices at peakshaving plants are offered based on visits to six facilities. The HF aspects of the recently promulgated DOT regulations are reviewed, and recommendations are made concerning how these regulations can be implemented utilizing standard HF practices. Finally, the integration of HF considerations into overall system safety is illustrated by a presentation of human error probabilities applicable to LNG operations and by an expanded fault tree analysis which explicitly recognizes man-machine interfaces.

  3. Improvement of plant reliability in PT. Badak LNG plant

    International Nuclear Information System (INIS)

    PT. Badak's LNG sales commitment has been steadily increasing, therefore, there has been more emphasis to improve and maintain the LNG plant reliability. From plant operation historical records, Badak LNG plant experienced a high number of LNG process train trips and down time for 1977 through 1988. The highest annual number of LNG plant trips (50 times) occurred in 1983 and the longest LNG process train down time (1259 train-hours) occurred in 1988. Since 1989, PT. Badak has been able to reduce the number of LNG process train trips and down time significantly. In 1994 the number of LNG process train trips and was 18 times and the longest LNG process train down time was 377 train-hours. This plant reliability improvement was achieved by implementing plant reliability improvement programs beginning with the design of the new facilities and continuing with the maintenance and modification of the existing facilities. To improve reliability of the existing facilities, PT. Badak has been implementing comprehensive maintenance programs, to reduce the frequency and down time of the plant, such as Preventive and Predictive Maintenance as well as procurement material improvement since PT. Badak location is in a remote area. By implementing the comprehensive reliability maintenance, PT. Badak has been able to reduce the LNG process train trips to 18 and down time to 337 train hours in 1994 with the subsequent maintenance cost reduction. The average PT. Badak plant availability from 1985 to 1995 is 94.59%. New facilities were designed according to the established PT. Badak design philosophy, master plan and specification. Design of new facilities was modified to avoid certain problems from past experience. (au)

    Natural gas, especially liquefied (LNG), is in position to participate in the energy growth now being triggered by strong worldwide economic growth, increasingly open markets, and expanding international trade. Natural gas is abundant, burns cleanly, and is highly efficient in combined-cycle, gas-turbine power plants. Moreover, the comparative remoteness of much of the resource base to established and emerging markets can make LNG a compelling processing and transportation alternative. Discussed here are the resource distribution and emerging market opportunities that can make LNG attractive for monetizing natural-gas reserves

    @@ Liquefied Natural Gas (LNG) is a low-temperature liquid mixture (-162℃) obtained by cooling and liquefaction of natural gas after deacidification and dehydration. In recent years, along with the surging global demand for energy and the drop of LNG cost, demand for LNG has been rising steadily. The primary underlying causes of that are the reduction of cost, the improvement of ship transportation and the changes in the form of trade. The tightening energy bottleneck brought by the rapid growth of China's economy might be well addressed by the active development of LNG industry, which can also help diversify the energy resources and facilitate the protection of environment.

    The procedure of reliability-based fatigue analysis of liquefied natural gas (LNG) carrier of membrane type under wave loads is presented. The stress responses of the hotspots in regular waves with different wave heading angles and wave lengths are evaluated by global ship finite element method (FEM). Based on the probabilistic distribution function of hotspots' short-term stress-range using spectral-based analysis, Weibull distribution is adopted and discussed for fitting the long-term probabilistic distribution of stress-range. Based on linear cumulative damage theory, fatigue damage is characterized by an S-N relationship, and limit state function is established. Structural fatigue damage behavior of several typical hotspots of LNG middle ship section is clarified and reliability analysis is performed. It is believed that the presented results and conclusions can be of use in calibration for practical design and initial fatigue safety evaluation for membrane type LNG carrier.

    Full Text Available This paper describes a classification method for ra w sensor data using a Fuzzy Inference System to detect the defects in large LNG tanks. Th e data is obtained from a Magnetic Flux Leakage (MFL sensing system which is usually used in the industry to located defects in metallic surfaces, such as tank floors. A robotic i nspection system has been developed in conjunction with the presented work which performs the same inspection tasks at much lower temperatures than human operators would thus reduci ng the shutdown time significantly which is typically of the order of 15-20 million Dollars per day. The main challenge was to come up with an algorithm that can map the human heuristics used by the MFL inspectors in field to locate the defects into an automated system and yet keep the algorithm simple enough to be deployed in near real-time applications. Unlike the human operation of the MFL equipment, the proposed technique is not very sensitive to the sen sor distance from the test surface and the calibration requirements are also very minimal whic h are usually a big impediment in speedy inspections of the floor by human operator. The use of wavelet decomposition with Coiflet waves has been utilized here for deconvolving the e ssential features of the signal before calculating the classification features. This wavel et was selected to its canny resemblance with the actual MFL signals that makes these wavelets ve ry natural basis function for decomposition..

    Highlights: • We estimated energy demand of building groups in a town using an in-house tool. • We developed an operation simulator to match supply–demand processes of energy. • Detailed technological information to operate the CES is provided by the simulation. • LNG demand is forecasted for the expansion of the CES up to 14 years in the future. - Abstract: We analyzed energy consumption by a newly constructed part of a city in Korea to forecast the LNG demand for 14 years. The electricity, heating, cooling, and hot-water demands for a cogeneration-based CES (Community Energy System) accommodating 86,000 people in 29,000 houses are estimated using load models developed through direct measurements and statistical surveys. Based on published occupancy rates and forecasts of the rate of increase in energy consumption by third parties through independent study, the energy demands were driven in the form of 8760-h time series for each of the 14 years. Next, we simulate the demand–supply matching processes of a specifically chosen cogeneration engine for the CES to forecast the LNG consumption and the electricity trade for each year. We simulated the demand–supply matching processes with an automation tool specifically developed for this study. The methodology we established in this study can be applied to similar problems which may arise anywhere in the world

    The floating production, storage and offload-ing system for liquefied natural gas (LNG-FPSO), is a new conceptual unit and an effective and realistic way for exploitation, recovery, storage, transportation and end-use applications of marginal gas fields and offshore associated-gas resources. However, a real LNG-FPSO unit cannot be built unless some breakthroughs in many key technologies are produced. Many unique characteris-tics of LNG-FPSO, such as restricted space, platform motion, LNG sloshing in inner storage tank and offload-ing system, which have not been considered in the onshore projects, are the most rigorous factors to be taken into account during design. In this paper, the overall layout of a typical LNG-FPSO unit is reviewed; the leading liquefaction technologies and processes are compared and discussed. Taking the effects of the vessel motion and limited space into account, the applicability of the main systems and key equipments of storage, offloading and power supply, are analyzed.

    LNG plants are characterized by their relatively low number in the world, diversity of processes involved, very high investment and operating costs. The fuel consumption of this type of facilities (about 15%) may double in given cases, when the frequency of untimely and volunteer shut downs is high. Then, the improvement of the reliability of the LNG chain in its overall will lead objectively to substantial decrease of energy costs. For reparable systems, availability is more often used as reliability indicator. In reliability point of view, the LNG chain must be assimilated to a unique complex system. However, modeling of complex systems, in reliability point of view or other, is always difficult in relation with the large dimensions of the space of phases. In this paper, a systemic approach is used to reduce the space of phases. A representation of subsystems by reliability diagrams permit a more easy calculation of probabilities associated with every phase. A bottom up technique allows the reconstitution of the global model of reliability of the chain. In an environment characterized by its weakness in statistical data, a Bayesian estimation approach is used to define the failure and repair rates of different equipments composing the LNG chain.

  18. Project financing knits parts of costly LNG supply chain

    International Nuclear Information System (INIS)

    The supply and distribution infrastructure of an LNG project requires project sponsors and LNG buyers to make large, interdependent capital investments. For a grassroots project, substantial investments may be necessary for each link in the supply chain: field development; liquefaction plant and storage; ports and utilities; ships; receiving terminal and related facilities; and end-user facilities such as power stations or a gas distribution network. The huge sums required for these projects make their finance ability critical to implementation. Lenders have become increasingly comfortable with LNG as a business and now have achieved a better understanding of the risks associated with it. Raising debt financing for many future LNG projects, however, will present new and increasingly difficult challenges. The challenge of financing these projects will be formidable: political instability, economic uncertainty, and local currency volatility will have to be recognized and mitigated. Described here is the evolution of financing LNG projects, including the Rasgas LNG project financing which broke new ground in this area. The challenges that lie ahead for sponsors seeking to finance future projects selling LNG to emerging markets are also discussed. And the views of leading experts from the field of project finance, specifically solicited for this article, address major issues that must be resolved for successful financing of these projects

  1. Implementation of the HNS Convention in the LNG Industry: Singularities, Stakes, Issues and GIIGNL Proposed Solutions

    International Nuclear Information System (INIS)

    The International Group of Liquefied Natural Gas Importers (GIIGNL) is a non-profit organization founded in December of 1971. It is composed of 56 member companies from 18 different countries across the world and involved in the importation of Liquefied Natural Gas. The main objective of the GIIGNL is to promote the development of activities related to LNG: purchasing, importing, processing, transportation, handling, re-gasification and various uses of LNG. For this purpose, the GIIGNL is particularly involved in promoting the state-of-the art technology in the LNG industry, in communicating about the economic fundamentals of the industry, in enhancing facility operations, in diversifying contractual techniques, and in developing industry positions to be taken in international agencies. As a member of the IOPC Fund since June 2007, the GIIGNL prepared this LNG overview in order to offer a better understanding to state delegations about this specific product and its market and to contribute to the debate on the implementation of the HNS Convention. the first chapter constitutes an introduction to the LNG Industry: presentation of an LNG Chain, overview of the global LNG trade and its growth rate, type of contracts, LNG tankers and technical transportation constraints, liquefaction and re-gasification plants around the world. The second chapter focuses on some singularities of the LNG industry that differentiate LNG from other Hazardous and Noxious Substances: LNG, a clean and unique product and activity, high standards and firm regulations concerning security and maritime safety, high level of investment required for an LNG chain, DES and FOB, the fundamental Incoterms of LNG sales and purchase. The third chapter presents the HNS Convention as potentially applicable to the LNG market: a two tier compensation regime - a new perspective for the LNG industry, a potential impact on LNG sales and purchase agreements, the importance of global HNS ratification within LNG

  3. LNG - Status in Denmark. Technology and potential. Project report

    Energy Technology Data Exchange (ETDEWEB)

    Naeslund, M.

    2012-05-15

    The interest for LNG both on a small and a large scale is increasing worldwide. The experiences and knowledge on LNG is limited in Denmark. The Danish gas companies' Technical Management Group (TCG) has asked for a status report including a technology description and an evaluation of the potential in Denmark. A survey of primarily small-scale LNG technology is done in the report. The focus is motivated by the new areas of gas utilisation that become possible with small-scale LNG. Small-scale LNG in this study is defined as LNG stored and used at the application or in an isolated gas grid. The small-scale use of LNG has today an almost negligible share of the total LNG trade but offers interesting new applications for gas utilisation. LNG on a small scale can be used primarily as: 1) Ship fuel. 2) Truck fuel (heavy duty long distance). 3) Individual users not connected to the natural gas grid. 4) Backup for upgraded biogas to individual users and vehicle fleets. 5) Security of supply or supply enhancement of heavily loaded parts of the gas grid. 6) Small-scale storage and/or peak shaving. All but the first topics are natural uses for the current Danish gas distributors. LNG as ship fuel may engage other specialized LNG companies. The report contains a technical description of the parts in primarily small-scale LNG handling and operation. Liquefaction, transport, storage, engine technologies, gas quality and safety aspects related to LNG are covered. There seem to be two more or less separate paths for LNG in Denmark, onshore and off-shore use. These are not, apparently, sharing their experiences and knowledge. Rules and regulations are also different which may create some problems in the interface, for example ship bunkering. Further studies are suggested in the area of gas quality and engine technologies and adaptation of foreign guidelines for small-scale installations to Danish conditions. These guidelines ought to be based on international standards and

    2011-12-01

    Full Text Available Increasing natural gas consumption, declining North Sea gas reserves, increased production costs and the deregulation of European gas and electricity markets have all combined to create new opportunities for LNG in Europe. In these circumstances, LNG represents an opportunity for many European countries to diversify their natural gas supply, while decreasing their dependence on Russian natural gas import at the same time. The largest exporters of LNG to Europe are Qatar, Algeria, Nigeria, Trinidad & Tobago, Egypt and Oman. Spain, Great Britain and France are the largest European importers of LNG. Spain has six LNG regasification terminals, followed by four in Great Britain, three in France, two in Italy and Turkey and finally Greece and Portugal with one terminal each. New LNG regasification terminals are currently under construction in Italy, Spain, Sweden and Netherlands. In addition, more than 30 new LNG terminal projects have been proposed around Europe. Italy plans to construct as many as 10 new regasification terminals, due to the strong orientation of its national energy policy towards LNG. Many European countries are strongly considering participating in the LNG chain for the first time, namely Albania, Cyprus, Ireland, Lithuania, Germany, Poland, Romania, Ukraine and Croatia. This paper focuses on a specific aspect of the LNG supply chain: the import facility (the paper is published in Croatian.

  6. The LNG Industry - 2010

    International Nuclear Information System (INIS)

    In 2010, global energy demand has recovered. Estimates for World Natural Gas consumption show a 7.3% increase compared with 2009 thanks to the economic rally and the cold winter conditions in Western countries. Due to the decline of indigenous productions in mature markets and to the development of new gas markets, international gas flows continued to expand, and total international gas trade increased by 10.9% compared with 2009. In this context, LNG flows recorded the largest growth with a 21% increase in 2010, the operational start-up of new liquefaction capacity in Qatar being the primary reason. By comparison, pipeline trade increased by 7%.

    Simultaneously with its exploitation of offshore hydrocarbon reservoirs Chile is developing the production and selling of LNG. Chile produces a large quantity of associated gas from its reservoirs at Megallanes and processes it at the Manantiales, Cullen and Posesion plants recovering propane, butane and natural gas liguids. The stripped gas is reinjected for pressure maintenance operations. With the completion of the LNG program full use of the gas will be achieved. It will totally meet the needs of combustible liquids for the central and northern parts of the country, a volume of 2200 million cu m/yr. For its treatment natural gas is sent through gas pipelines to the LNG plant at Cabo Negro. By means of a cooling process, the gas is cooled to -160 C where it becomes a liquid and its volume is reduced by a factor of 600. It is then stored in tanks at atmospheric pressure.

  11. Asia-pacific LNG outlook

    International Nuclear Information System (INIS)

    Full text: There are powerful drivers at work in the Asia-Pacific region for clean and affordable energy. Liquefied Natural Gas (LNG) is providing a vital solution to this need. With demand in the region expected to grow from 70 million tonnes per annum to 110 million tonnes per annum by 2010, there are significant opportunities for the Australian natural gas industry and the country. The North West Shelf Venture, Australia's only LNG producer, currently provides some 7.5 million tonnes of LNG to Japanese customers. On 2 April 2001 a 50% expansion in LNG production was announced. The A$2.4 billion expansion project will be ready for start up in mid 2004 and will supply additional LNG to the Japanese customers. This increased demand and supply comes on the back of significant restructuring of the Japanese energy market. In addition to Japan, supply opportunities for LNG from Australia are emerging in China, Korea and Taiwan and the expectation is that there will be an increased reliance on LNG as an energy source. The challenge for Australian companies will be to ensure that opportunities are maximised for current and future LNG producers. David Maxwell, General Manager Commercial of Woodside Energy Limited, Operator of the North West Shelf Venture, will explore the current state of the LNG market, the forces at work in this industry and the outlook for LNG in the region.

    The project's main task was to review logistical, technical and economic feasibility for using Liquefied Natural Gas (LNG) and Compressed Natural Gas (CNG) as fuel for ship propulsion and the supply of LNG or CNG to Danish ports from existing natural gas lines, trucks or by ship. The following key findings are related to the use of natural gas as fuel for ships in Denmark: Natural gas as propulsion fuel in ships: 1) Advantages: Provide solution to present air emission challenges 2) Barriers: Capital investments large 3) Synergies: Developments in Norway and Baltic Sea area 4) Economy: Positive case for operation for large consumers 5) Future: Develop bunkering options for short sea shipping LNG: 6) Propulsion technology in ships is mature and proven 7) Distribution network not yet developed for use in ships 8) Safety concerns are demanding but manageable 9) Can enter existing bunkering value chain CNG: 10) Well developed for land based transport, not yet for shipping 11) Distribution network for natural gas exists in Denmark 12) Safety concerns are demanding but manageable 13) No seaborne CNG value chains in operation An immediate focus on the ferry sector in Denmark will reap benefits on a relatively short time scale. For the short sea shipping sector away to promote the conversion to natural gas is to support the development of storage and bunkering facilities in main ports. Given the general expectations in the shipping community LNG will presumably be the de facto choice at least for the 5-10 years ahead and the demand for facilities and bunkers will be for LNG. (LN)

    The increasing demand for natural gas could increase the number and frequency of Liquefied Natural Gas (LNG) tanker deliveries to ports across the United States. Because of the increasing number of shipments and the number of possible new facilities, concerns about the potential safety of the public and property from an accidental, and even more importantly intentional spills, have increased. While improvements have been made over the past decade in assessing hazards from LNG spills, the existing experimental data is much smaller in size and scale than many postulated large accidental and intentional spills. Since the physics and hazards from a fire change with fire size, there are concerns about the adequacy of current hazard prediction techniques for large LNG spills and fires. To address these concerns, Congress funded the Department of Energy (DOE) in 2008 to conduct a series of laboratory and large-scale LNG pool fire experiments at Sandia National Laboratories (Sandia) in Albuquerque, New Mexico. This report presents the test data and results of both sets of fire experiments. A series of five reduced-scale (gas burner) tests (yielding 27 sets of data) were conducted in 2007 and 2008 at Sandia's Thermal Test Complex (TTC) to assess flame height to fire diameter ratios as a function of nondimensional heat release rates for extrapolation to large-scale LNG fires. The large-scale LNG pool fire experiments were conducted in a 120 m diameter pond specially designed and constructed in Sandia's Area III large-scale test complex. Two fire tests of LNG spills of 21 and 81 m in diameter were conducted in 2009 to improve the understanding of flame height, smoke production, and burn rate and therefore the physics and hazards of large LNG spills and fires.

The above mentioned training program was held over a period of 20 hours, and was divided between theory and practice. In the theoretical part, the characteristics of the product, the history of accidents and the emergency response procedures were covered. In the practical part, 3000 gallons of LNG were utilized where the behavior of the product could be confirmed following a confined leak, thereby verifying the efficacy of the emergency control resources. The teaching process of the course was developed in the company through the preparation of specific procedures, emergency plans and the formation of internal instructors. (author)

  16. Steady-state and dynamic simulation study on boil-off gas minimization and recovery strategies at LNG exporting terminals

    Science.gov (United States)

    Kurle, Yogesh

    Liquefied natural gas (LNG) is becoming one of the prominent clean energy sources with its abundance, high calorific value, low emission, and price. Vapors generated from LNG due to heat leak are called boil-off gas (BOG). As world-wide LNG productions are increasing fast, BOG generation and handling problems are becoming more critical. Also, due to stringent environmental regulations, flaring of BOG is not a viable option. In this study, typical Propane-and-Mixed-Refrigerant (C3-MR) process, storage facilities, and loading facilities are modeled and simulated to study BOG generation at LNG exporting terminals, including LNG processing, storage, and berth loading areas. Factors causing BOG are presented, and quantities of BOG generated due to each factor at each location are calculated under different LNG temperatures. Various strategies to minimize, recover, and reuse BOG are also studied for their feasibility and energy requirements. Rate of BOG generation during LNG loading---Jetty BOG (JBOG)---changes significantly with loading time. In this study, LNG vessel loading is simulated using dynamic process simulation software to obtain JBOG generation profile and to study JBOG recovery strategies. Also, fuel requirements for LNG plant to run steam-turbine driven compressors and gas-turbine driven compressors are calculated. Handling of JBOG generated from multiple loadings is also considered. The study would help proper handling of BOG problems in terms of minimizing flaring at LNG exporting terminals, and thus reducing waste, saving energy, and protecting surrounding environments.

  17. LNG - the challenge of growth

    International Nuclear Information System (INIS)

    LNG growth prospects - both in the Far East and Atlantic Basin - have never been better. Natural gas is responding strongly to the green momentum and to its clear competitive advantage in power generation. To meet growing demand, the major energy buyers are turning increasingly to large remote reserves of gas which often can only be delivered as LNG. But, the market will decide when and which LNG projects are developed - and the trigger will be price. LNG will compete head-on not only with low priced oil and coal but, in some markets, also with long-haul pipeline gas. This paper outlines regional demand and supply opportunities for LNG and then considers the challenges that the LNG industry must now tackle if it is to realistically expect a larger share of the world's energy market

  18. LNG demand, shipping will expand through 2010

    International Nuclear Information System (INIS)

    The 1990s, especially the middle years, have witnessed a dramatic turnaround in the growth of liquefied-natural-gas demand which has tracked equally strong natural-gas demand growth. This trend was underscored late last year by several annual studies of world LNG demand and shipping. As 1998 began, however, economic turmoil in Asian financial markets has clouded near-term prospects for LNG in particular and all energy in general. But the extent of damage to energy markets is so far unclear. A study by US-based Institute of Gas Technology, Des Plaines, IL, reveals that LNG imports worldwide have climbed nearly 8%/year since 1980 and account for 25% of all natural gas traded internationally. In the mid-1970s, the share was only 5%. In 1996, the most recent year for which complete data are available, world LNG trade rose 7.7% to a record 92 billion cu m, outpacing the overall consumption for natural gas which increased 4.7% in 1996. By 2015, says the IGT study, natural-gas use would surpass coal as the world''s second most widely used fuel, after petroleum. Much of this growth will occur in the developing countries of Asia where gas use, before the current economic crisis began, was projected to grow 8%/year through 2015. Similar trends are reflected in another study of LNG trade released at year end 1997, this from Ocean Shipping Consultants Ltd., Surrey, U.K. The study was done too early, however, to consider the effects of the financial problems roiling Asia

  1. The LNG industry - 2008

    International Nuclear Information System (INIS)

    The average annual growth of the world primary energy consumption has been 2.2% over the last ten years, with the highest growth rate observed for 2004 (+4.7%). In 2007, world primary energy consumption registered a 2.4% increase, still exceeding the 10-year average but less than for the four previous years. As for the previous years, the Asia Pacific region shows the most important increase in volume for 2007, rising by 5% and accounting for two-third of the global growth (China alone accounts in 2007 for more than half of this global growth, as was already the case in 2005 and 2006). Over the last ten years, the world energy consumption rose from 8920 106 toe in 1998 to 11099 106 toe in 2007, a 24.4% overall increase. For the seventh year running, coal has increased its share of the overall energy market, up to 28.6%. It should be noted that nuclear power decreased by 2%, Germany and Japan accounting for more than 90% of this decline. The growth of natural gas consumption in 2007 (+3.1%) was higher than in 2006 (+2.4%). The US accounted for nearly half of the global increase. Strong growth was also observed in China (+19.9%), representing the second largest increment to world gas consumption. Inversely, the EU consumption decreased (-1.6%) for the second year in a row. The market share for natural gas remained stable in 2007 (23.8%) compared to 2006 (23.6%)(1). Estimates for the marketed production of natural gas in 2008(2) show a rise of about 3.4% over 2007. The share of LNG in the gas trade accounts for 27% of the total (excluding trade within the Former Soviet Union and United Arab Emirates).

    In the main, the global LNG industry can look back on 2014 as another year of relative stagnation with LNG trade reaching 239.2 MMT, a 1% increase over 2013, but just below 2011 levels. Although one new liquefaction plant came on stream in May in Papua New Guinea and one expansion train started producing in Algeria, disappointments in Angola and Egypt and slowdown in Qatar limited the volume of additional LNG supply. Low demand in South Korea as well as slower than expected growth in China contributed to loosen the market tightness observed in recent years, foreboding the return of a buyers' market as the year progressed. Other highlights in the past year's review of LNG imports are the remarkable gain in India, ahead of the U.K and Japan's demand increase, and the arrival of Lithuania as the world's 30. importer with a floating storage and re-gasification unit (FSRU). On the supply side, Queensland Curtis was on the brink at year-end of joining the producers' rank and managed to load its first cargo in December. Nigeria showed the second largest addition of supply (after PNG) attributable to a much improved feed-gas supply. During the second half of the year a sharp decrease in crude oil prices combined with a looser supply situation in the Pacific drove down prices in Asia, where spot prices were halved between March and October of last year. On the supply side, this price drop in Asia will inevitably slow down or defer development of expensive new supply projects. On the demand side, it has begun to translate into the return of flexible LNG cargoes to Europe, where spot prices have been disconnected from oil prices for some time. In this context of demand and price uncertainty, traditional procurement models are changing, as new players with different business models emerge, new procurement alliances are being formed and new commercial offerings are being structured; all mainly in the pursuit of enhanced flexibility both in terms of

    Although liquefied natural gas (LNG) storage tanks might seem to be the most passive components in the LNG plant or ship, this appearance of quiescence arises only because we too easily imagine LNG storage to be like the storage of water. The contents of an LNG storage tank are in continuous dynamic reaction because of heat leak into the tanks, changes in barometric pressure, and the circumstances surrounding the addition and withdrawal of LNG.

  4. The Venezuelan LNG project

    International Nuclear Information System (INIS)

    Substantial reserves of unassociated gas were discovered by Lagoven offshore the Paria Peninsula, Eastern Venezuela during 1978- 1982. In 1988/89 a Feasibility Study conducted by Lagoven and Shell identified the potential for a LNG Project to utilize these reserves. This study proposed piping the gas ashore to a 2 train liquefaction plant at Mapire from where an estimated 4 1/2 million tonnes of LNG per year would be exported to the USA. As a result of the Study, Lagoven entered into an agreement in February 1991 with Shell, Exxon and Mitsubishi with the objective of undertaking the work necessary to assess project viability. This agreement anticipates that once various legal and congressional approvals and acceptable fiscal terms have been obtained, a Joint Venture company will be formed to complete work and reach an investment decision. Currently the Project activities including one of the world's largest 3D seismic surveys, are being coordinated by a Project Team drawn from all the Participants

    The World Wide Web consortium has developed an Extensible Markup Language (XML) to support the building of better information management infrastructures. The scientific computing community realizing the benefits of XML has designed markup languages for scientific data. In this paper, we propose a XML based scientific data management ,facility, XDMF. The project is motivated by the fact that even though a lot of scientific data is being generated, it is not being shared because of lack of standards and infrastructure support for discovering and transforming the data. The proposed data management facility can be used to discover the scientific data itself, the transformation functions, and also for applying the required transformations. We have built a prototype system of the proposed data management facility that can work on different platforms. We have implemented the system using Java, and Apache XSLT engine Xalan. To support remote data and transformation functions, we had to extend the XSLT specification and the Xalan package.

  8. The LNG industry in 2011. Press revue

    International Nuclear Information System (INIS)

    The outlook of the LNG industry in 2011 is presented as a revue of press articles: The role of LNG as a flexible and secure energy source as well as the prompt response to provide back-up through additional supplies and cargo diversions to compensate for the sudden loss of nuclear capacity in Japan - with sellers exercising due price restraint in view of the human tragedy - has been a credit to the industry. The increase in production capacity in 2009 and 2010, in particular from Qatar, had permitted the necessary buffer to cope much better with the demand surge than during past disruptions (such as the aftermath of the Chuetsu earthquake in late 2007). Undoubtedly, the marked shift over the last decade in the industry's prevailing business model towards global trade, destination flexibility and portfolio play has also facilitated the rapid response. As the total volume of LNG trade is very much determined by the availability of supply, 2011 has seen a growth of 9.4% over 2010, mainly as a result of the full availability of the six Qatar mega-trains over the past year. On the demand side the two traditional basins have shown very contrasting trends: 15% higher LNG off-take in Asia (the five major markets all increasing between 37.4% and 8.9%), versus a 1.7% decrease in the Atlantic Basin. Cargo diversions and an increasing number of reloads have boosted the exports from the Atlantic Basin to Asia in 2011 to more than 14 million tons (equivalent to more than 200 large size cargoes). Remarkable is also the fast growth in new markets in Latin America and in the Middle East - albeit from a small base - with counter-seasonal but varying demand, offering attractive arbitrage opportunities to portfolio play. Not surprising then that 2011 has seen another hike in spot and short-term trade, not just in absolute terms but also as a percentage of total trade (50% over 2010, 25.4% of total trade). The outlook for LNG is strong and its global demand prospects further

It is also worth noticing that the cost estimation models used in this study sometimes contain large steps for the different cost situations.

In order to indicate the extent to which some key parameters affect the final cost, sensitivity analysis is carried out on the purchase price and the terminal costs. The results show that the Norwegian LNG costs 560-608 SEK/MWh (road), 570-689 SEK/MWh (railroad) and 537-555 SEK/MWh (sea). Algerian LNG costs 315-324 SEK/MWh (sea). The large difference between Norwegian and Algerian LNG is caused primarily by the much lower purchase costs of Algerian LNG, and also due to the difference in sea shipping costs. The purchase cost is about 80 % of the total cost for all cases. The transport cost is between 3 and 6 % and the terminal costs the balance, making it a larger component in the cases of Algerian than Norwegian LNG. It is shown that LNG could be an alternative to secure the Natural Gas supply after the Danish supply has run out. It has proven safe and the market is getting more and more mature. The fate of base-load LNG is largely determined by the other Natural Gas projects in the Nordic countries.

    2012-06-01

    THIS ARTICLE DEVELOPS A FORMAL MODEL FOR COMPARING THE COST STRUCTURE OF THE TWO MAIN TRANSPORT OPTIONS FOR NATURAL GAS: liquefied natural gas (LNG) and pipelines. In particular, it evaluates how variations in the prices of natural gas and greenhouse gas emissions affect the relative cost-efficiency of these two options. Natural gas is often promoted as the most environmentally friendly of all fossil fuels, and LNG as a modern and efficient way of transporting it. Some research has been carried out into the local environmental impact of LNG facilities, but almost none into aspects related to climate change. This paper concludes that at current price levels for natural gas and CO2 emissions the distance from field to consumer and the volume of natural gas transported are the main determinants of transport costs. The pricing of natural gas and greenhouse emissions influence the relative cost-efficiency of LNG and pipeline transport, but only to a limited degree at current price levels. Because more energy is required for the LNG process (especially for fuelling the liquefaction process) than for pipelines at distances below 9100 km, LNG is more exposed to variability in the price of natural gas and greenhouse gas emissions up to this distance. If the prices of natural gas and/or greenhouse gas emission rise dramatically in the future, this will affect the choice between pipelines and LNG. Such a price increase will be favourable for pipelines relative to LNG.

  15. Key issues considered at LNG 13

    International Nuclear Information System (INIS)

    In the past few years, deregulation of the gas markets throughout the world has changed the way LNG projects can be brought into realisation. Gone are the days when large consortia of buyers could aggregate demand into quantities that made an LNG project economic. Today's market is typified by buyers requesting greater flexibility in volumes, shorter contract terms and reduced exposure to take-or-pay clauses. This means that the onus is on the producer to aggregate volume to make a large project viable, and to find flexible supply options as demand increases. As a result, there is an increasing ability to source LNG from excess capacity around the world, as has been demonstrated with the extended shutdown of the Arun LNG plant in Indonesia. Although some flexibility exists for the supply of LNG, it is unlikely that a world market where LNG is freely traded will develop. LNG projects will still require long-term contracts to ensure project financing. Furthermore, the 'LNG world' will remain separated into two regions the Atlantic and Asia-Pacific basins with only small amounts of 'spot' trading occurring between them. This is primarily due to the increased shipping costs associated with the global movement of LNG, and thus the ability to compete with closer sources of LNG and pipeline gas. Australia's position and its challenges in the LNG market is analysed

    A major increase in LNG trade, expected from the 1990s onwards, is quite significant in that a new framework will be developed. These changes and developments may well prove to be some of the most notable that have ever occurred in the 30-year history of the LNG industry. All over the world, new buyers and sellers are entering the scene, while in Japan, small and medium-size businesses are switching to LNG. Transporters and LNG carriers are also expecting an increase in their numbers. We are about to see a wide-ranging diversification in terms of the geography and the size of the companies that deal with LNG. Safety continues to be the main issue in promoting the development of the LNG market. The wider the spread of LNG, the greater the need will be for further development of the systems and organizations for transferring safety technology and skills. In addition to enhancing safety, it will be necessary to seek harmony with the social environment.

    A study of the chaotic behavior of liquefied natural gas (LNG) after stratification in the main stream region of a storage tank was conducted. Based on non-linear dynamics, a 2-dimensional Rayleigh-Benard con-vection model was developed to simulate the convection, Lorenz equations of LNG convection were deduced from conservation equations, and the Runge-Kutta method was used to solve the equations. The results showed that when Pr = 1.33, 106 < r < 1470, chaos was obtained, which meant that the velocity field and the temperature field were highly unsteady. In addition, the influence of temperature and scale factor on the solutions and the corresponding range of parameters were studied. The results revealed that the chaos in LNG convection resulted from the interaction of buoyancy and viscid forces. A small quantity of heat impacting the storage tank would lead to a strong and unstable convection of LNG in the main stream region.

    The submerged combustion vaporizer (SCV) is indispensable general equipment for liquefied natural gas (LNG) receiving terminals. In this paper, numerical simulation was conducted to get insight into the flow and heat transfer characteristics of supercritical LNG on the tube-side of SCV. The SST model with enhanced wall treatment method was utilized to handle the coupled wall-to-LNG heat transfer. The thermal-physical properties of LNG under supercritical pressure were used for this study. After the validation of model and method, the effects of mass flux, outer wall temperature and inlet pressure on the heat transfer behaviors were discussed in detail. Then the non-uniformity heat transfer mechanism of supercritical LNG and effect of natural convection due to buoyancy change in the tube was discussed based on the numerical results. Moreover, different flow and heat transfer characteristics inside the bend tube sections were also analyzed. The obtained numerical results showed that the local surface heat transfer coefficient attained its peak value when the bulk LNG temperature approached the so-called pseudo-critical temperature. Higher mass flux could eliminate the heat transfer deteriorations due to the increase of turbulent diffusion. An increase of outer wall temperature had a significant influence on diminishing heat transfer ability of LNG. The maximum surface heat transfer coefficient strongly depended on inlet pressure. Bend tube sections could enhance the heat transfer due to secondary flow phenomenon. Furthermore, based on the current simulation results, a new dimensionless, semi-theoretical empirical correlation was developed for supercritical LNG convective heat transfer in a horizontal serpentine tube. The paper provided the mechanism of heat transfer for the design of high-efficiency SCV.

In addition, First Nations are cooperative overall and 8 of them (out of 20 impacted by LNG projects) have already signed revenue-sharing agreements with proponents. However, the development of projects has been slowed by uncertainties regarding the economics of the projects and difficulties in signing sales agreements. For a typical BC LNG plant, the break-even Asian sale price has been estimated at $11.8/mmbtu by CEDIGAZ in the base case scenario, which corresponds to a JCC price of $81/bbl for oil-indexed contracts with a 14.5% oil slope. The low case break-even price is $8.6/mmbtu while the high case price is $16.1/mmbtu. Considering oil long term price trend, Canadian projects should be profitable but will probably remain less competitive than US-produced LNG indexed to the Henry Hub price. Based on six objective criteria, CEDIGAZ has identified a group of four front-runner projects which, as of February 2015, stand the best chances to succeed: Pacific Northwest LNG, Goldboro LNG, LNG Canada and Douglas Channel LNG. The second group is composed of seven projects, dubbed challengers which are less advanced, but still have some chances to succeed.

  4. LNG links remote supplies and markets

    International Nuclear Information System (INIS)

    Liquefied natural gas (LNG) has established a niche for itself by matching remote gas supplies to markets that both lacked indigenous gas reserves and felt threatened in the aftermath of the energy crises of the 1970s and 1980s. It has provided a cost-effective energy source for these markets, while also offering an environmentally friendly fuel long before that was fashionable. The introduction of natural-gas use via LNG in the early years (mostly into France and Japan) has also allowed LNG to play a major role in developing gas infrastructure. Today, natural gas, often supplied as LNG, is particularly well-suited for use in the combined cycle technology used in independent power generation projects (IPPs). Today, LNG players cannot simply focus on monetizing gas resources. Instead, they must adapt their projects to meet the needs of changing markets. The impact of these changes on the LNG industry has been felt throughout the value chain from finding and producing gas, gas treatment, liquefaction, transport as a liquid, receiving terminals and regasification, and finally, to consumption by power producers, industrial users, and households. These factors have influenced the evolution of the LNG industry and have implications for the future of LNG, particularly in the context of worldwide natural gas

The paper is based on clinical reports of 21 cases of primary and secondary dysmenorrhea treated with the frameless LNG-IUS. Three typical examples of young women between 16 and 20 years of age, who presented with moderate-to-severe primary dysmenorrhea associated with heavy menstrual bleeding, are presented as examples. Following pelvic examination, including vaginal sonography, a frameless LNG-IUS, releasing 20 µg of LNG/day, was inserted. The three patients developed amenorrhea, or scanty menstrual bleeding, and absence of pain complaints within a few months. We conclude that continuous, intrauterine progestogen delivery could be a treatment of choice of this inconvenient condition. In addition, the good experiences with the frameless LNG-IUS in other studies suggests that the frameless design may be preferred over a framed LNG-IUS, as the absence of a frame, resulting in optimal tolerance, is particularly advantageous in these women.

    An environmental radiation calibration facility has been constructed by the Radiation and Nuclear Sciences unit of Queensland Health at the Forensic and Scientific Services Coopers Plains campus in Brisbane. This facility consists of five low density concrete pads, spiked with a NORM source, to simulate soil and effectively provide a number of semi-infinite uniformly distributed sources for improved energy response calibrations of radiation equipment used in NORM measurements. The pads have been sealed with an environmental epoxy compound to restrict radon loss and so enhance the quality of secular equilibrium achieved. Monte Carlo models (MCNP),used to establish suitable design parameters and identify appropriate geometric correction factors linking the air kerma measured above these calibration pads to that predicted for an infinite plane using adjusted ICRU53 data, are discussed. Use of these correction factors as well as adjustments for cosmic radiation and the impact of surrounding low levels of NORM in the soil, allows for good agreement between the radiation fields predicted and measured above the pads at both 0.15 m and 1 m.

    Full Text Available LNG tanks are complex in design and building process and high in costs, so LNG tank technology is one of the most advanced ones in the field of energy, which has been monopolized by foreign companies for a long time. In order to work out LNG tank technology domestically, China National Offshore Oil Corporation (CNOOC for short, the largest LNG importer in China, develops a LNG tank technology system “CGTank®” successfully in reference to the design and construction experience of domestic and foreign companies, after years of scientific research in tackling difficult problems. This system presents four traits as follows. First, a set of calculation software is developed independently by CNOOC, and the tanks in all operating conditions are calculated after 3D hologram and multi-point contact model of fluid-solid coupling effect is built up. Second, earthquake effect research and inner tank check research are improved innovatively by means of response spectrum analysis after European standards are introduced. Third, it is put forward for the first time that the stress strength discrimination standard is based on the principal stress which is obtained by means of the maximum shearing failure theory. And fourth, a large LNG full-capacity tank technology package with completely independent intellectual property right is established. The “CGTank®” system was first applied in the Tianjin LNG demonstration project, which has passed all indicator tests and is now in operation smoothly. The project is provided with the core tank design technology by CNOOC Gas and Power Group and with the EPC by CNOOC Engineering Co., Ltd. The independent LNG tank technology can be applied in a wide scope and it is favorable for impelling domestic production of LNG industry completely.

  16. LNG: a commodity in the making

    International Nuclear Information System (INIS)

    Although still far from being a commodity, LNG is undoubtedly emerging as an essential vector for world gas expansion. The flexibility it procures in terms of supply is of prime importance for future market equilibrium. Despite a number of uncertainties and constraints liable to thwart the realisation of the most optimistic growth prospects, the LNG trade remains wedded to rapid growth of about 7%/year by 2020, boosting its share of world gas trade to some 38% by that horizon.

    Enterotoxigenic Escherichia coli (ETEC) is a major cause of morbidity in children under 5 years of age in low- and middle-income countries and a leading cause of traveler's diarrhea worldwide. The ability of ETEC to colonize the intestinal epithelium is mediated by fimbrial adhesins, such as CS21 (Longus). This adhesin is a type IVb pilus involved in adherence to intestinal cells in vitro and bacterial self-aggregation. Fourteen open reading frames have been proposed to be involved in CS21 assembly, hitherto only the lngA and lngB genes, coding for the major (LngA) and minor (LngB) structural subunit, have been characterized. In this study, we investigated the role of the LngA, LngB, LngC, LngD, LngH, and LngP proteins in the assembly of CS21 in ETEC strain E9034A. The deletion of the lngA, lngB, lngC, lngD, lngH, or lngP genes, abolished CS21 assembly in ETEC strain E9034A and the adherence to HT-29 cells was reduced 90%, compared to wild-type strain. Subcellular localization prediction of CS21 proteins was similar to other well-known type IV pili homologs. We showed that LngP is the prepilin peptidase of LngA, and that ETEC strain E9034A has another peptidase capable of processing LngA, although with less efficiency. Additionally, we present immuno-electron microscopy images to show that the LngB protein could be localized at the tip of CS21. In conclusion, our results demonstrate that the LngA, LngB, LngC, LngD, LngH, and LngP proteins are essential for CS21 assembly, as well as for bacterial aggregation and adherence to HT-29 cells.

    LNG custody transfer measurements at large terminals have been based on ship tank level gauging for more than 50 years. Flow meter application has mainly been limited to process control in spite of the promise of simplified operations, potentially smaller uncertainties and better control over the measurements for buyers. The reason for this has been the lack of LNG flow calibration standards as well as written standards. In the framework of the EMRP1 ‘Metrology for LNG’ project, Van Swinden Laboratory (VSL) has developed a primary LNG mass flow standard. This standard is so far the only one in the world except for a liquid nitrogen flow standard at the National Institute of Standards and Technology (NIST). The VSL standard is based on weighing and holds a Calibration and Measurement Capability (CMC) of 0.12% to 0.15%. This paper discusses the measurement principle, results of the uncertainty validation with LNG and the differences between water and LNG calibration results of four Coriolis mass flow meters. Most of the calibrated meters do not comply with their respective accuracy claims. Recommendations for further improvement of the measurement uncertainty will also be discussed.

  2. Structural response of cargo containment systems in LNG carriers under ice loads

    International Nuclear Information System (INIS)

    Gas exploration has been extended into the Arctic region such as in the Russian Arctic area, because of the increasing demand for energy resources. As a result, shipping in ice-covered seas is also increasing. Many technical issues are involved in ensuring the safety of liquefied natural gas (LNG) ships during the transportation. This paper discussed an investigation of ship-ice interaction scenarios for possible operation routes in Arctic areas. Six scenarios were selected to study the structural response of cargo containment systems (CCS) in both membrane and spherical types of LNG ships. For selected ship-ice interaction scenarios, ice loads and loading areas in the hull structure were determined based on the energy theory. The configurations of LNG carriers were discussed and illustrated. The paper also outlined the assessment criteria and structure analysis procedures. It was concluded that the strength of the CCS of membrane-type LNG carrier and the strength of the skirt structure of spherical-type LNG carrier were strong enough under the design ice loads. 13 refs., 9 tabs., 18 figs

    In order to reduce the atmospheric pollution generated by ships, the International Marine Organization has established Emission Controlled Areas. In these areas, nitrogen oxides, sulphur oxides and particulates emission is strongly controlled. From the beginning of 2015, the ECA covers waters 200 nautical miles from the coast of the US and Canada, the US Caribbean Sea area, the Baltic Sea, the North Sea and the English Channel. From the beginning of 2020, strong emission restrictions will also be in force outside the ECA. This requires newly constructed ships to be either equipped with exhaust gas cleaning devices or propelled with emission free fuels. In comparison to low sulphur Marine Diesel and Marine Gas Oil, LNG is a competitive fuel, both from a technical and economical point of view. LNG can be stored in vacuum insulated tanks fulfilling the difficult requirements of marine regulations. LNG must be vaporized and pressurized to the pressure which is compatible with the engine requirements (usually a few bar). The boil-off must be controlled to avoid the occasional gas release to the atmosphere. This paper presents an LNG system designed and commissioned for a Baltic Sea ferry. The specific technical features and exploitation parameters of the system will be presented. The impact of strict marine regulations on the system's thermo-mechanical construction and its performance will be discussed. The review of possible flow-schemes of LNG marine systems will be presented with respect to the system's cost, maintenance, and reliability.

  7. A structural and stochastic optimal model for projections of LNG imports and exports in Asia-Pacific.

    2016-06-01

    The Asia-Pacific region, the largest and fastest growing liquefied natural gas (LNG) market in the world, has been undergoing radical changes over the past few years. These changes include considerable additional supplies from North America and Australia, and a recent LNG price slump resulting from an oil-linked pricing mechanism and demand uncertainties. This paper develops an Asia-Pacific Gas Model (APGM), based on a structural, stochastic and optimising framework, providing a valuable tool for the projection of LNG trade in the Asia-Pacific region. With existing social-economic conditions, the model projects that Asia-Pacific LNG imports are expected to increase by 49.1 percent in 2020 and 95.7 percent in 2030, compared to 2013. Total LNG trade value is estimated to increase to US$127.2 billion in 2020 and US$199.0 billion in 2030. Future LNG trade expansion is mainly driven by emerging and large importers (i.e., China and India), and serviced, most importantly, by new supplies from Australia and the USA. The model's projected results are sensitive to changes in expected oil prices, pricing mechanisms, economic growth and energy policies, as well as unexpected geopolitical-economic events.

    As the world enters the 21st Century, policy makers around the world are grappling with issues related to energy security, energy poverty, global climate change, and the need to reduce greenhouse gas emissions while meeting an expected increase in demand for all energy sources. As a clean burning fuel, many policy leaders have suggested that LNG can play an important role as the world struggles to develop a more environmental sustainable energy future. Others claim that the safety and environmental impact of LNG, including life-cycle emissions, may nullify any clean burning benefit LNG might otherwise provide.

  12. Retail LNG handbook. Retail LNG and The Role of LNG Import Terminals. Report by the GIIGNL Technical Study Group on the possible role of LNG import terminals within the emerging Retail LNG Market

    International Nuclear Information System (INIS)

    The natural gas and liquefied natural gas (LNG) industries are changing. The influx of supply, low prices, and environmental benefits of natural gas are driving consumers to convert from other fossil fuels. Natural gas consumers on pipeline systems have the ability to benefit, but for those not connected, LNG may be the only opportunity to convert to natural gas. As this market evolves, a unique opportunity may emerge for some existing participants in the LNG market and could lead to a shift in business focus, potentially adding to or even transforming the traditional role of LNG Import Terminals. As surmised by the GIIGNL's Technical Study Group (TSG) at the outset of their endeavor, virtually every member company had historical experience with, was in the midst of expanding its services to include, or was actively engaged in the study of, Retail LNG. The market drivers, value propositions, trends and future prospects for Retail LNG that have widely been publicized were generally confirmed although in an overall more conservative outlook. As a representative body of experienced, long term LNG Import Terminal operators, GIIGNL was uniquely qualified to stress in its Handbook the importance of managing the inherent risk associated with LNG, the application of suitable codes and standards and the use of proper equipment. The study of the aspects of LNG supply and use including safety, security, staffing, equipment siting, and operations is hoped to provide an illustrative framework form which the industry can jointly move towards best practices. While Retail LNG is considered by many to be 'new' there is substantial historical experience with all aspects of the market. LNG Import Terminals, including the experience and competence of their staffing, can play a key role in not only the incubation and growth of the Retail market, but the molding and shaping of regulatory framework, applicable codes and standards and operational best practices.

  13. The economic value of LNG in the Korean manufacturing industry

    International Nuclear Information System (INIS)

    Although LNG is an important input to industrial production for manufacturing firms, its economic value has been rarely investigated in the literature. This paper attempts to estimate the economic value of LNG in Korea's manufacturing sector by employing the concept of the value of marginal product (VMP). For this, we used data on 328 firms using LNG as an input. Two types of production functions (the Cobb–Douglas and trans-log functions) are applied. The result of the specification test indicates that the trans-log function is more appropriate for estimating the data. The output elasticity and VMP of industrial LNG are estimated to be 0.1346 and KRW 6844 (USD 6.22) per m3, respectively. The results have important implications for various areas of industrial LNG management. For example, any cost–benefit analysis of new projects providing industrial LNG requires information on the economic value of industrial LNG. In addition, such information is useful for the Korean government's future policies on LNG pricing. - Highlights: • We estimate the economic value of LNG in the Korean manufacturing industry. • We employ the concept of the value of marginal product (VMP). • The VMP of industrial LNG is estimated to be KRW 6844 (USD 6.22) per m3. • It significantly outweighs the price of industrial LNG (KRW 629.4 per m3)

However, a doubling of LNG truck demand will initialize network commercialization in the modeling base year, 2012 (the same year Clean Energy Corp. launched their national LNG network) in California and then gradually establish in other hotspot regions in Mid-West and Mid-Atlantic throughout the time horizon. The model shows that trucking routes in California are highly commercial due to high traffic volume and regional advantages. The model can be used by industry to inform necessary policies and to plan future infrastructure deployment along trucking routes that are likely to provide the highest returns.

    1996-07-01

    The study aims at clarifying the framework for possible LNG exports from Northern Russia and focuses on the European natural gas markets. The first stage provides general background information on the market structure and related topics. In the second stage this information is used to develop a formal market model and subject it to simulations with various assumptions of the future gas supply. The model is described and results from simulations are given. In the first stage facts from the history of the European natural gas market are outlined. Underlying conditions for the development of natural gas markets in Europe are addressed. The EU has been promoting trade liberalisation in the energy sector but most counties resist freer gas trade across the boarders. New infrastructure development for natural gas are either underway or planned. Some important projects are mentioned. Gas in a global perspective is discussed. The cost structure of the LNG chain is mentioned and an overview of existing LNG export capacities world-wide and major reception terminals in Europe and the USA is given. The second stage employs a scenario analysis to evaluate the economic effects of hypothetical LNG deliveries from Northern Russia. The model is developed for the analysis of West European natural gas markets and designed to allow users to create a structural system of interconnected producers and market regions. Basic assumptions for the evolution of natural gas markets till 2005 is developed and base case scenarios calculated for the years 2000 and 2005 and used as a point of reference for the alternative scenarios considered. According to the analysis the introduction of a new LNG supplier in the European gas market will inflict a substantial loss upon all the existing producers. The primary keys to this result are the assumptions made for gas demand and supply capacity. The LNG alternative will hardly be approved for purely economic reasons as long as the Russians maintain

  19. Russian LNG: The Long Road to Export

    International Nuclear Information System (INIS)

    On December 1, 2013 a law on liquefied natural gas (LNG) export liberalization came into legal force in Russia. The law grants two categories of companies other than Russia's state gas giant Gazprom and its subsidiary companies the right to export LNG: (1) users of mineral resources that have a license to construct an LNG plant or to send their gas production for liquefaction, and (2) companies that are more than 50% owned by the Russian government, for gas produced from Russian offshore fields or under production-sharing agreements. This is-without exaggeration-a historic decision for the Russian gas industry, the path to which was certainly not easy. Recent years have seen a radical change in the global economic climate, which has changed the dynamics of the European gas market (gas demand decline and Russian gas import reduction, changing pricing mechanism for a much higher share of spot indexing, European Commission anti-trust investigations against Gazprom, etc) and is increasingly pushing Russia to diversify its gas exports. However, diversifying exports through the development of LNG has proven to be not so simple. Over the past 20 years, with the exception of the Sakhalin-2 project, structured under a project-sharing agreement (PSA) rather than in the framework of national legislation, all other projects failed to come close to completion. The Kharasavey and Baltic LNG projects were abandoned in the early stages of project evaluation, while the Shtokman project progressed to the point of the operating company being created, but in the end was postponed indefinitely. The first stage of LNG development in Russia ended in failure. However, the Russian government considers the development of LNG exports to be a priority, which can be evidenced in all official policy papers. It is believed that LNG will help in achieving a set of objectives, namely: increasing the absolute volume of exports, allowing the country to enter into previously inaccessible markets

    A plant operator training simulator is developed for training the plant operators as well as for design verification of plant control system (PCS) and plant protection system (PPS) for the Kharkov Institute of Physics and Technology Neutron Source Facility. The simulator provides the operator interface for the whole plant including the sub-critical assembly coolant loop, target coolant loop, secondary coolant loop, and other facility systems. The operator interface is implemented based on Experimental Physics and Industrial Control System (EPICS), which is a comprehensive software development platform for distributed control systems. Since its development at Argonne National Laboratory, it has been widely adopted in the experimental physics community, e.g. for control of accelerator facilities. This work is the first implementation for a nuclear facility. The main parts of the operator interface are the plant control panel and plant protection panel. The development involved implementation of process variable database, sequence logic, and graphical user interface (GUI) for the PCS and PPS utilizing EPICS and related software tools, e.g. sequencer for sequence logic, and control system studio (CSS-BOY) for graphical use interface. For functional verification of the PCS and PPS, a plant model is interfaced, which is a physics-based model of the facility coolant loops implemented as a numerical computer code. The training simulator is tested and demonstrated its effectiveness in various plant operation sequences, e.g. start-up, shut-down, maintenance, and refueling. It was also tested for verification of the plant protection system under various trip conditions.

    To provide decision-making basis for the selection of arrival and departure organization scheme for LNG vessel, a multi-objective lattice order decision-making theory is applied to the evaluation and selection of organization scheme. Combined with the characteristics of LNG vessel manoeuvring, the evaluation index system for the selection of arrival and departure organization scheme for LNG vessel is constructed , in which the management factors such as safety, economy, operability, etc, are considered. The entropy method is adopted to calculate the weights of the indices, and the method is tested and illustrated by an example. The result indicates that the proposed method is applicable, and the model is of certain value for reference for the selection of arrival and departure organization scheme for LNG vessel.%为给液化天然气(Liquefied Natural Gas,LNG)船舶进出港组织方案选择提供决策依据,将多目标格序决策理论运用到组织方案评价比选中.结合LNG船舶操纵特点构建针对方案安全性、经济性、可操作性等管理因素的LNG船舶进出港组织方案比选的评价指标体系.运用熵值法计算指标权重,并结合实例对该方法进行检验与说明.结果表明该方法较为适用,对LNG船舶进出港组织方案的比选有一定借鉴价值.

    Full Text Available In this paper, a nonlinear model for locating service facilities is introduced in a competitive ‎ region. In the proposed model the factors of travel time, quality of service facilities and price ‎ are considered that are the most important effective factors in attracting and maintaining the ‎ customers in the competitive environments. For identifying the customers’ probabilistic ‎ behavior in selecting the competitor’s and entering firm’s facilities, the spatial interaction ‎ model and Logit function are used. Since the decision making for locating is not only based on ‎ the sale quantity and market demand captured and ignoring other important organizational ‎ goals such as minimizing the cost may provide problems in long term for firms, therefore in ‎ addition to the capturing demand, the fixed cost of locating is considered in the model that ‎ will provide better results in the real world problems. Due to the computational complexity, a ‎ genetic algorithm is developed for solving the model. The numerical results verify the ‎ performance of the proposed model and effectiveness of ‏ ‏ ‎ the genetic algorithm in solving it ‏ ‏ and show that the study of costumers’ ‎ ‏ ‏ probabilistic demand considering the factors of price, ‎ travel time and quality of service facilities has the major role in the increasing of sale and profit ‎ of the entering firm so that, in spite of selecting the most appropriate locations by the ‎ competitor, the ‏ ‏ sale and profit quantities of entering firm are more than the competitor’s, in the ‎ equal situation of price, quality and number of facilities. ‎

    Last year, 51 LNG carriers were delivered in the world. From January to February this year, more than 10 LNG carriers have been deliveredglobally. Some shipowners are planning to expand LNG carrier fleet, which is a stark contrast to the look of the three main ship types which is embarrassing. As the recognized clean fuel, natural gas plays an important role in carbon politics and low carbon economy. At present, LNG powered vessel is growing vigorously. LNG fueled vessels have also emerged in Europe. Now, discussion about natural gas application on inland water transport is gradually warming up. Although there are still many technical problems to be solved about LNG powered vessel, the trend is irreversible.

    A group of European gas transportation companies within the European Gas Research Group launched in 2007 the 'MOLAS' Project to provide a software program for the analysis of the Liquefied Natural Gas (LNG) ageing process during ship transportation. This program contains two different modeling approaches: a physical algorithm and an 'intelligent' model. Both models are fed with the same input data, which is composed of the ship characteristics (BOR and capacity), voyage duration, LNG composition, temperature, pressure, and volume occupied by liquid phase at the port of origin, together with pressure at the port of destination. The results obtained are the LNG composition, temperature and liquid volume at the port of destination. Furthermore, the physical model obtains the evolution over time of such variables en route as it is based on unsteady mass balances over the system, while the i-model applies neural networks to obtain regression coefficients from historical data composed only of origin and destination measurements. This paper describes both models and validates them from previous published models and experimental data measured in ENAGAS LNG regasification plants. (author)

    2015-06-01

    Full Text Available A thermal Neutron Radiography (NR facility based on the use of thermal neutron flux, generated by the PULSTAR experimental reactor, has been designed and simulated using the MCNPX code. The key objective of the proposed facility is to deliver thermal neutron flux in this range for variable values of L/D ratio, instantaneously with acceptable values for all NR parameters. Thus, with suitable aperture and collimators designs, optimization for the parameters for thermal NR was achieved, for a wide range of the collimator ratio. The short time requirements for obtaining the radiography images justify the use of the proposed system for ‘real time radiography’. The system was designed under the limitation that the total Dose Equivalent Rate does not exceed at the external shield surface the limit recommended by ICRP-26.

    2014-02-01

    At the request of GDF Suez, a Rough Order of Magnitude (ROM) cost estimate was prepared for the design, construction, testing, and data analysis for an experimental series of large-scale (Liquefied Natural Gas) LNG spills on land and water that would result in the largest pool fires and vapor dispersion events ever conducted. Due to the expected cost of this large, multi-year program, the authors utilized Sandia's structured cost estimating methodology. This methodology insures that the efforts identified can be performed for the cost proposed at a plus or minus 30 percent confidence. The scale of the LNG spill, fire, and vapor dispersion tests proposed by GDF could produce hazard distances and testing safety issues that need to be fully explored. Based on our evaluations, Sandia can utilize much of our existing fire testing infrastructure for the large fire tests and some small dispersion tests (with some modifications) in Albuquerque, but we propose to develop a new dispersion testing site at our remote test area in Nevada because of the large hazard distances. While this might impact some testing logistics, the safety aspects warrant this approach. In addition, we have included a proposal to study cryogenic liquid spills on water and subsequent vaporization in the presence of waves. Sandia is working with DOE on applications that provide infrastructure pertinent to wave production. We present an approach to conduct repeatable wave/spill interaction testing that could utilize such infrastructure.

    Tsuta, T.; Yamamoto, K.; Tetsuka, S.; Koyama, K. [Tokyo Gas Co., Ltd. (Japan)

    1997-11-01

    The Tokyo Gas LNG terminals are among the major energy centers of the Tokyo area, supplying 8 million customers with city gas, and also supplying fuel for thermal power generation at the neighboring thermal power plant operated by the Tokyo Electric Power Company. For this reason, in the event of an emergency at the terminal operators have to be able to respond quickly and accurately to restore operations and prevent secondary damage. Modern LNG terminals are highly reliable and are equipped with backup systems, and occurrences of major trouble are now almost nil. Operators therefore have to be trained to respond to emergencies using simulators, in order to heighten their emergency response capabilities. Tokyo Gas Co., Ltd. has long been aware of the need for simulators and has used them in training, but a new large-scale, real-time simulator has now developed in response to new training needs, applying previously accumulated expertise to create a model of an entire LNG terminal incorporating new features. The development of this new simulator has made possible training for emergencies affecting an entire terminal, and this has been very effective in raising the standards of operators. (au)

    The location of commercial facility decides the benefit of the operator to a large degree. Existing location methods can express the static relationships between site selection result and location factors, but there still are some limites when express the dynamic and uncertain relationship between them. Hence, a dynamic, stochastic and forecastable location model should be built which can introduce the customer's behavior into the model and combine the macro pattern and micro spatial interaction. So the authors proposes Geosim-LM based on MAS. Geosim-LM has 3 kinds of agents, CustAgent, SiteAgent and GovAgent. They represent the customers, commercial fercilities and government. The land type, land price and traffic are the model environment. Then Geosim-LM is applied in the bank branches site evaluation and selection in Liwan district, Guangzhou. In existing bank branches site evaluation, there are 70% consistent in score grade between result of Geosim-LM after 200 round runing and actual rebust location. It proves the model is reliable and feasible. The conclusions can be get from the paper. MAS have advantages in location choice than existed methods. The result of Geosim-LM running can powerfully proves that building location model based on MAS is feasible.

    The growing importance of liquefied natural gas (LNG) to global energy demand has increased interest in the possible hazards associated with its storage and transportation. Concerning the event of an LNG spill, a study was performed on the relationship between the distance at which the lower flammability limit (LFL) concentration occurs and that corresponding to the visible contour of LNG vapor clouds. A parameter called the dispersion safety factor (DSF) has been defined as the ratio between these two lengths, and two expressions are proposed to estimate it. During an emergency, the DSF can be a helpful parameter to indicate the danger of cloud ignition and flash fire. PMID:23305750

    SSPA experiences a growing interest in twin skeg ships as one attractive green ship solution. The twin skeg concept is well proven with obvious advantages for the design of ships with full hull forms, restricted draft or highly loaded propellers. SSPA has conducted extensive hull optimizations studies of LNG ships of different size based on an extensive hull data base with over 7,000 models tested, including over 400 twin skeg hull forms. Main hull dimensions and different hull concepts such as twin skeg and single screw were of main interest in the studies. In the present paper, one twin skeg and one single screw 170 K LNG ship were designed for optimally selected main dimension parameters. The twin skeg hull was further optimized and evaluated using SHIPFLOW FRIENDSHIP design package by performing parameter variation in order to modify the shape and positions of the skegs. The finally optimized models were then built and tested in order to confirm the lower power demand of twin skeg designed compaed with the signle screw design. This paper is a full description of one of the design developments of a LNG twin skeg hull, from early dimensional parameter study, through design optimization phase towards the confirmation by model tests.

    The acceleration of beams of unstable nuclei has opened up new research frontiers. Experiments at existing accelerators, and particularly at the first generation of radioactive ion beam facilities, have demonstrated convincingly that unique information becomes accessible. Critical cross sections for astrophysical processes that were impossible to obtain previously, qualitatively new and unexpected nuclear structure effects in nuclei far from stability, completely new approaches to studies of nuclear decays, reactions and structure, all have triggered much excitement for this new dimension in nuclear research. To explore this new dimension, an extension of present technical capabilities and facilities is needed. This need and its scientific basis were discussed in various workshops and symposia and in the Isospin Laboratory (ISL) White Paper. A report by the European community was published recently on prospects of radioactive beam facilities in Europe, and some next-generation projects for such facilities are starting in both Europe and Japan.

    Full Text Available Ever growing energy industry requires larger quantities of LNG to be transported by bigger ships between terminals. Every day, new kind of large vessels created by new technologies, and these are used to trade around the globe. This is the dynamic change in shipping industry. But on the other hand these new vessels need to safely berth to existing terminals which we may accept as more static part of the trade. Thus this study born by the request of Ege Gaz Aliaga LNG Terminal management to determine if it is safe to berth to the terminal by a new breed of large LNG carrier type named as Q-Flex and Q-Max. Transas Bridge Simulator NTPRO 5000 series was used in this study for extensive experiments which had been simulated by the use of hook function. During the study, every force applied to mooring hooks and dolphins by the ship lines were divided into 3 dimensions and then measured by simulation experiments. With analysis of the data, required hook and dolphins strengths were determined for the safe mooring arrangements. Upon the completion of the study Ege Gaz Aliaga LNG Terminal became the first safe berth for Q-Flex type vessels in the Mediterranean and the Black Sea. And finally all experiments were confirmed with real life experience when the first Q-Flex type LNG carrier berthed to the Ege Gaz Aliaga LNG Terminal.

  13. LNG pool fire spectral data and calculation of emissive power.

    Science.gov (United States)

    Raj, Phani K

    2007-04-11

    Spectral description of thermal emission from fires provides a fundamental basis on which the fire thermal radiation hazard assessment models can be developed. Several field experiments were conducted during the 1970s and 1980s to measure the thermal radiation field surrounding LNG fires. Most of these tests involved the measurement of fire thermal radiation to objects outside the fire envelope using either narrow-angle or wide-angle radiometers. Extrapolating the wide-angle radiometer data without understanding the nature of fire emission is prone to errors. Spectral emissions from LNG fires have been recorded in four test series conducted with LNG fires on different substrates and of different diameters. These include the AGA test series of LNG fires on land of diameters 1.8 and 6m, 35 m diameter fire on an insulated concrete dike in the Montoir tests conducted by Gaz de France, a 1976 test with 13 m diameter and the 1980 tests with 10 m diameter LNG fire on water carried out at China Lake, CA. The spectral data from the Montoir test series have not been published in technical journals; only recently has some data from this series have become available. This paper presents the details of the LNG fire spectral data from, primarily, the China Lake test series, their analysis and results. Available data from other test series are also discussed. China Lake data indicate that the thermal radiation emission from 13 m diameter LNG fire is made up of band emissions of about 50% of energy by water vapor (band emission), about 25% by carbon dioxide and the remainder constituting the continuum emission by luminous soot. The emissions from the H2O and CO2 bands are completely absorbed by the intervening atmosphere in less than about 200 m from the fire, even in the relatively dry desert air. The effective soot radiation constitutes only about 23% during the burning period of methane and increases slightly when other higher hydrocarbon species (ethane, propane, etc.) are

  14. Technical bases for establishing a salt test facility

    International Nuclear Information System (INIS)

    The need for a testing facility in which radioactive materials may be used in an underground salt environment is explored. No such facility is currently available in salt deposits in the United States. A salt test facility (STF) would demonstrate the feasibility of safely storing radioactive waste in salt and would provide data needed to support the design, construction, licensing, and operation of a radioactive waste repository in salt. Nineteen issues that could affect long-term isolation of waste materials in a salt repository are identified from the most pertinent recent literature. The issues are assigned an overall priority and a priority relative to the activities of the STF. Individual tests recommended for performance in the STF to resolve the 19 issues are described and organized under three groups: waste package performance, repository design and operation, and site characterization and evaluation. The requirements for a salt test facility are given in the form of functional criteria, and the approach that will be used in the design, execution, interpretation, and reporting of tests is discussed

  18. LNG cascading damage study. Volume I, fracture testing report.

    Energy Technology Data Exchange (ETDEWEB)

    Petti, Jason P.; Kalan, Robert J.

    2011-12-01

    As part of the liquefied natural gas (LNG) Cascading Damage Study, a series of structural tests were conducted to investigate the thermal induced fracture of steel plate structures. The thermal stresses were achieved by applying liquid nitrogen (LN{sub 2}) onto sections of each steel plate. In addition to inducing large thermal stresses, the lowering of the steel temperature simultaneously reduced the fracture toughness. Liquid nitrogen was used as a surrogate for LNG due to safety concerns and since the temperature of LN{sub 2} is similar (-190 C) to LNG (-161 C). The use of LN{sub 2} ensured that the tests could achieve cryogenic temperatures in the range an actual vessel would encounter during a LNG spill. There were four phases to this test series. Phase I was the initial exploratory stage, which was used to develop the testing process. In the Phase II series of tests, larger plates were used and tested until fracture. The plate sizes ranged from 4 ft square pieces to 6 ft square sections with thicknesses from 1/4 inches to 3/4 inches. This phase investigated the cooling rates on larger plates and the effect of different notch geometries (stress concentrations used to initiate brittle fracture). Phase II was divided into two sections, Phase II-A and Phase II-B. Phase II-A used standard A36 steel, while Phase II-B used marine grade steels. In Phase III, the test structures were significantly larger, in the range of 12 ft by 12 ft by 3 ft high. These structures were designed with more complex geometries to include features similar to those on LNG vessels. The final test phase, Phase IV, investigated differences in the heat transfer (cooling rates) between LNG and LN{sub 2}. All of the tests conducted in this study are used in subsequent parts of the LNG Cascading Damage Study, specifically the computational analyses.

    Controlling the evaporation phenomenon of liquefied natural gas (LNG) in storage tanks is strongly related to heat transfer under ambient conditions. In the natural gas liquefaction complex of Skikda located in Algeria, control and follow-up in the exploitation of the LNG storage tanks is done only by observing a temperature profile of the internal wall of the tank, using thermocouples laid out according to the height. This practice is important to detect the defects of heat insulation in the tank wall and makes it possible to avoid all the risks of incidents due to excessive evaporation. This paper discussed the development of a simple numerical model that simulated the rate of evaporation of LNG in a storage tank under real storage conditions at a liquefaction complex in Skikda (Algeria). The paper presented the equations for the modelling of heat transfer in the storage tank taking into account all the modes of heat exchange between the ambient conditions and the stored LNG. The paper also discussed the method of resolution. It was concluded that the evaporation rates predicted by the model were in agreement with the configurations corresponding to the real operating conditions. In addition, the results demonstrated the sensitivity of the rate of evaporation to various parameters like the LNG liquid level in the tank, the atmospheric temperature, the emissivity coefficient or incidental solar flow. 6 refs., 1 tab., 12 figs.

    Antarctica contains areas where the environment and terrain are more similar to regions on the Moon and Mars than any other place on Earth. These features offer opportunities for simulations to determine performance capabilities of people and machines in harsh, isolated locales. The Sasakawa International Center for Space Architecture (SICSA) plans to create a facility on Antarctica for research, planning, and demonstrations in support of planetary exploration. The Antarctic Planetary Testbed (APT) will be financed and utilized by public and private organizations throughout the world. Established on a continent owned by no country, it can serve as a model for cooperation between spacefaring nations. APT science and technology programs will expand knowledge about the nature and origin of our solar system, and will support preparations for human settlements beyond Earth that may occur within the first quarter of the next century. The initial APT facility, conceived to be operational by the year 1992, will be constructed during the summer months by a crew of approximately 12. Six to eight of these people will remain through the winter. As in space, structures and equipment systems will be modular to facilitate efficient transport to the site, assembly, and evolutionary expansion. State-of-the-art waste recovery/recycling systems are also emphasized due to their importance in space.

  6. Hawaii energy strategy project 2: Fossil energy review. Task 3 -- Greenfield options: Prospects for LNG use

    Energy Technology Data Exchange (ETDEWEB)

    Breazeale, K. [ed.; Fesharaki, F.; Fridley, D.; Pezeshki, S.; Wu, K.

    1993-12-01

    This paper begins with an overview of the Asia-Pacific LNG market, its major players, and the likely availability of LNG supplies in the region. The discussion then examines the possibilities for the economic supply of LNG to Hawaii, the potential Hawaiian market, and the viability of an LNG project on Oahu. This survey is far from a complete technical assessment or an actual engineering/feasibility study. The economics alone cannot justify LNG`s introduction. The debate may continue as to whether fuel diversification and environmental reasons can outweigh the higher costs. Several points are made. LNG is not a spot commodity. Switching to LNG in Hawaii would require a massive, long-term commitment and substantial investments. LNG supplies are growing very tight in the Asia-Pacific region. Some of the environmental benefits of LNG are not entirely relevant in Hawaii because Hawaii`s air quality is generally excellent. Any air quality benefits may be more than counterbalanced by the environmental hazards connected with large-scale coastal zone construction, and by the safety hazards of LNG carriers, pipelines, etc. Lastly, LNG is not suitable for all energy uses, and is likely to be entirely unsuitable for neighbor island energy needs.

  10. Northwest Asia - gas market outlook: LNG vs. pipeline gas

    International Nuclear Information System (INIS)

    The share of natural gas in Northeast Asia's energy mix is quite low despite that the region currently dominates the world LNG trade. In the long term, the region's rapid expansion of gas demand in the coming decades looks very likely, but the LNG dominance in the region's gas market will collapse in parallel with the introduction of a long distance pipeline gas. The most likely timing of pipeline gas introduction in Northeast Asian gas market seems to be during the second half of the next decade. (Author)

  11. New spatial clustering-based models for optimal urban facility location considering geographical obstacles

    Science.gov (United States)

    Javadi, Maryam; Shahrabi, Jamal

    2014-03-01

    The problems of facility location and the allocation of demand points to facilities are crucial research issues in spatial data analysis and urban planning. It is very important for an organization or governments to best locate its resources and facilities and efficiently manage resources to ensure that all demand points are covered and all the needs are met. Most of the recent studies, which focused on solving facility location problems by performing spatial clustering, have used the Euclidean distance between two points as the dissimilarity function. Natural obstacles, such as mountains and rivers, can have drastic impacts on the distance that needs to be traveled between two geographical locations. While calculating the distance between various supply chain entities (including facilities and demand points), it is necessary to take such obstacles into account to obtain better and more realistic results regarding location-allocation. In this article, new models were presented for location of urban facilities while considering geographical obstacles at the same time. In these models, three new distance functions were proposed. The first function was based on the analysis of shortest path in linear network, which was called SPD function. The other two functions, namely PD and P2D, were based on the algorithms that deal with robot geometry and route-based robot navigation in the presence of obstacles. The models were implemented in ArcGIS Desktop 9.2 software using the visual basic programming language. These models were evaluated using synthetic and real data sets. The overall performance was evaluated based on the sum of distance from demand points to their corresponding facilities. Because of the distance between the demand points and facilities becoming more realistic in the proposed functions, results indicated desired quality of the proposed models in terms of quality of allocating points to centers and logistic cost. Obtained results show promising

  12. Egypt emerges : with help from some Canadian companies, Alexandria is striving to grab a spot on the global LNG stage

    Energy Technology Data Exchange (ETDEWEB)

    Lorenz, A.

    2006-12-15

    Two new liquefied natural gas (LNG) plants recently built in Egypt are a testimony to the country's renewed natural gas industry. This article presented details of Canadian companies who are now operating in Egypt as a result of the Egyptian government's decision to include gas as a commodity from which foreign companies could earn a profit in the late 1980s. Apache negotiated a lease on a 2.2 million acre block southwest of Giza called the Qarun Block along with a partner called Phoenix Resources Companies Inc. in 1992, and has since made significant gas discoveries. In March 2006, the company posted record gross oil and gas production of 119,500 barrels per day and 501 million cubic feet per day. Egypt currently produces 3.5 billion cubic feet of natural gas per day. Approximately half is consumed locally and the balance is liquefied for export to Europe and Asian markets. The 2 LNG plants in Egypt currently process 700 million cubic feet and 1 billion cubic feet per day respectively. Egypt's Nile Delta is emerging as a world-class hydrocarbon basin, where companies such as BP have been exploring and producing since 1992. BP is confident that Egypt's potential reserves exceed 100 trillion cubic feet and that its aggressive exploration strategy is expected to form the foundation of a significant LNG business. Calgary-based company Centurion has established a presence in Egypt and has formed a partnership with Royal Dutch/Shell Group. The company has granted Shell 2 concessions in exchange for the construction of a gas train worth $1.5 billion capable of handling 500 million cubic feet per day of gas. It was concluded that while current global prices for natural gas are still too low to make it economical to ship Egyptian LNG to North America, higher prices may mean that LNG currently being transported to Europe may eventually end up in North American LNG terminals. 9 figs.

    A novel method for fabrication of superhydrophobic surfaces was developed by facile coating various metal oxide nanoparticles, including ZnO, Al2O3 and Fe3O4, on various substrates followed by treatment with polydimethylsiloxane (PDMS) via chemical vapor deposition (CVD) method. Using ZnO nanoparticles as a model, the changes in the surface chemical composition and crystalline structures of the metal oxide nanoparticles by PDMS treatment were investigated by X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR) analysis. The results show that the combination of the improved surface roughness generated from of the nanoparticles aggregation with the low surface-energy of silicon-coating originated from the thermal pyrolysis of PDMS would be responsible for the surface superhydrophobicity. By a simple dip-coating method, we show that the metal oxide nanoparticles can be easily coated onto the surfaces of various textural and dimensional substrates, including glass slide, paper, fabric or sponge, for preparation of superhydrophobic surfaces for different purpose. The present strategy may provide an inexpensive and new route to surperhydrophobic surfaces, which would be of technological significance for various practical applications especially for separation of oils or organic contaminates from water.

  15. Fire performance of LNG carriers insulated with polystyrene foam.

    Science.gov (United States)

    Havens, Jerry; Venart, James

    2008-10-30

    Analysis of the response of a liquid-full Moss Sphere LNG tank insulated with polystyrene foam to an engulfing LNG fire indicates that current regulatory requirements for pressure relief capacity sufficient to prevent tank rupture are inadequate. The inadequacy of the current requirements stems primarily from two factors. Firstly, the area of the Moss Sphere protruding above what would be the nominal deck on a conventional carrier, which is protected only by a steel weather cover from exposure to heat from a tank-engulfing fire, is being underestimated. Secondly, aluminum foil-covered polystyrene foam insulation applied to the exterior of the LNG tank is protected above the deck only by the steel weather cover under which the insulation could begin to melt in as little as 1-3 min, and could completely liquefy in as few as 10 min. U.S. and International Regulations require that the insulations on the above-deck portion of tanks have approved fire proofing and stability under fire exposure. Polystyrene foam, as currently installed on LNG carriers, does not appear to meet these criteria. As a result of these findings, but giving no consideration to the significant potential for further damage if the polystyrene should burn, the boil-off rate is predicted to be an order-of-magnitude higher than provided for by current PRV sizing requirements.

  16. Risk-Based Ranking Experiences for Cold War Legacy Facilities in the United States

    International Nuclear Information System (INIS)

    Over the past two decades, a number of government agencies in the United States have faced increasing public scrutiny for their efforts to address the wide range of potential environmental issues related to Cold War legacies. Risk-based ranking was selected as a means of defining the relative importance of issues. Ambitious facility-wide risk-based ranking applications were undertaken. However, although facility-wide risk-based ranking efforts can build invaluable understanding of the potential issues related to Cold War legacies, conducting such efforts is difficult because of the potentially enormous scope and the potentially strong institutional barriers. The U.S. experience is that such efforts are worth undertaking to start building a knowledge base and infrastructure that are based on a thorough understanding of risk. In both the East and the West, the legacy of the Cold War includes a wide range of potential environmental issues associated with large industrial complexes of weapon production facilities. The responsible agencies or ministries are required to make decisions that could benefit greatly from information on the relative importance of these potential issues. Facility-wide risk-based ranking of potential health and environmental issues is one means to help these decision makers. The initial U.S. risk-based ranking applications described in this chapter were ''ground-breaking'' in that they defined new methodologies and approaches to meet the challenges. Many of these approaches fit the designation of a population-centered risk assessment. These U.S. activities parallel efforts that are just beginning for similar facilities in the countries of the former Soviet Union.

  17. Data base of reactor physics experimental results in Kyoto University critical assembly experimental facilities

    International Nuclear Information System (INIS)

    The Kyoto University critical assembly experimental facilities belong to the Kyoto University Research Reactor Institute, and are the versatile critical assembly constructed for experimentally studying reactor physics and reactor engineering. The facilities are those for common utilization by universities in whole Japan. During more than ten years since the initial criticality in 1974, various experiments on reactor physics and reactor engineering have been carried out using many experimental facilities such as two solidmoderated cores, a light water-moderated core and a neutron generator. The kinds of the experiment carried out were diverse, and to find out the required data from them is very troublesome, accordingly it has become necessary to make a data base which can be processed by a computer with the data accumulated during the past more than ten years. The outline of the data base, the data base CAEX using personal computers, the data base supported by a large computer and so on are reported. (Kako, I.)

    The initial scope of work for this project included: (1) Improving the FEM3A advanced turbulence closure module, (2) Adaptation of FEM3A for more general applications, and (3) Verification of dispersion over rough surfaces, with and without obstacle using the advanced turbulence closure module. These work elements were to be performed by Chemical Hazards Research Center (CHRC), Department of Chemical Engineering, University of Arkansas as a subcontractor to Gas Technology Institute (GTI). The tasks for GTI included establishment of the scientific support base for standardization of the FEM3A model, project management, technology transfer, and project administration. Later in the course of the project, the scope of work was modified by the National Energy Technology Laboratories (NETL) to remove the emphasis on FEM3A model and instead, develop data in support of NETL's FLUENT modeling. With this change, GTI was also instructed to cease activities relative to FEM3A model. GTI's technical activities through this project included the initial verification of FEM3A model, provision of technical inputs to CHRC researchers regarding the structure of the final product, and participation in technical discussion sessions with CHRC and NETL technical staff. GTI also began the development of a Windows-based front end for the model but the work was stopped due to the change in scope of work. In the meantime, GTI organized a workshop on LNG safety in Houston, Texas. The workshop was very successful and 75 people from various industries participated. All technical objectives were met satisfactorily by Dr. Jerry Havens and Dr. Tom Spicer of CHRC and results are presented in a stand-alone report included as Appendix A to this report.

  20. LNG, Competition and Security of Supply: the Role of Shipping

    International Nuclear Information System (INIS)

    In the last few years, one of the main concerns of European Union in the energetic field has been that of facilitating the safeguard of raw materials' security of supply, especially that of natural gas. Import through LNG chain, that is, through the employment of LNG tankers for gas transportation, has been identified by the European Council as one of the instruments to achieve these goals. In fact, import via LNG does not require, for the importer, such investments as to determine an indissoluble physical tie between producer and buyer, as happens for transport via pipeline (Chernyavska et al., 2002). In other words, investments in pipelines are very specific. Moreover, as they are made in order to support specific transactions, contracts usually take the form of long-term agreements with minimum off take requirements (take or pay clauses): such contracts definitely contribute to the cartelization of the market, hindering competition. Unlike investments in pipelines, those in the LNG chain present a much lower degree of specificity: in fact, even though the construction of a re gasification plant is generally tied to the stipulation of a long-term agreement (with take or pay clause), LNG chain costs have significantly decreased over time (until a few years ago) and, moreover, it is getting increasingly common that part of plant capacity is made available for spot transactions. What's more, once the contract is expired and the investment is sunk, the importer may satisfy his gas supply needs on the basis of his relative gains. As far as LNG import contractual practices are concerned, significant changes have started to take places in the last few years, both in terms of agreements' length average duration has significantly decreased and in terms of price indexation in the most developed markets LNG price is tied to gas spot price (IEA, 2006). One of the many possible advantages of transport via LNG is that liquefied gas enables European importers to widen their gas

    Full Text Available Public transport is one of the facilities available in Malaysia. Overwhelming demand from the community has demanded public transport as an alternative for some people to do their daily activities. The increasing of Malaysian population brought many problems to the environment especially traffic congestion problem. The Government spends a lot of money to overcome this problem [10]. Public transport has been upgraded to ensure user comfort. Most people in the city are more interested in using railway transport as traffic congestion and travel time accuracy is better than other public transport [1, 5]. To influence public demand, the facilities available at the train station should be complete [3, 5]. The choice of location for the study are Batu Gajah station (station 1 and Kluang station (station 2 for rural services while Bandar Tasik Selatan station (station 3 and KL Central station (station 4 for urban services. The results of this study showed that, based on data and information obtained from field survey work and the feedback questionnaires from users, basic facilities at railway stations surveyed for urban and rural services can be identified and listed. An analysis of the status of the facilities at railway stations can be established through the safety of passengers and observations in the field. The facilities available at the urban service station are more complete than in rural service station. Facilities at railway station should be improved to attract people using the facilities.

  3. The tariffs of use of liquefied natural gas transportation networks and facilities

    International Nuclear Information System (INIS)

    The new tariff proposals for the use of natural gas transportation networks were transmitted to the French Ministry of economy, finances and industry on October 27, 2004 by the commission of energy regulation. These proposals have been adopted and are the object of three legislative texts: the decree no. 2005-607 from May 27 2005 relative to the tariffing rules, the by-law from May 27, 2005 relative to the definition of balancing areas, and the advice from May 27, 2005 relative to the tariffs of use of natural gas transportation networks. In application of article 7 of the law from January 3, 2003, the implementation of the first tariffs of use of natural gas transportation networks and of liquefied natural gas (LNG) facilities is defined in the decree no. 2004-994 from September 21, 2004. On the main transportation network, the tariffing is of 'input-output' type and does not depend on the distance, while at the regional network scale, the tariffing is linked with the distance. The tariff of use of LNG facilities is the sum of 4 terms: a fixed term applied to each batch unloaded at the methane terminal, a term proportional to the unloaded LNG quantities, a term depending on the duration of use of LNG storage facilities and a term covering the gas consumptions of LNG facilities. This document gathers these different legislative texts with their appendixes. (J.S.)

  4. Analysis of Hanford-based Options for Sustainable DOE Facilities on the West Coast

    2012-06-30

    Large-scale conventional energy projects result in lower costs of energy (COE). This is true for most renewable energy projects as well. The Office of Science is interested in its facilities meeting the renewable energy mandates set by Congress and the Administration. Those facilities on the west coast include a cluster in the Bay Area of California and at Hanford in central Washington State. Land constraints at the California facilities do not permit large scale projects. The Hanford Reservation has land and solar insolation available for a large scale solar project as well as access to a regional transmission system that can provide power to facilities in California. The premise of this study is that a large-scale solar project at Hanford may be able to provide renewable energy sufficient to meet the needs of select Office of Science facilities on the west coast at a COE that is competitive with costs in California despite the lower solar insolation values at Hanford. The study concludes that although the cost of solar projects continues to decline, estimated costs for a large-scale project at Hanford are still not competitive with avoided power costs for Office of Science facilities on the west coast. Further, although it is possible to transmit power from a solar project at Hanford to California facilities, the costs of doing so add additional costs. Consequently, development of a large- scale solar project at Hanford to meet the renewable goals of Office of Science facilities on the west coast is currently uneconomic. This may change as solar costs decrease and California-based facilities face increasing costs for conventional and renewable energy produced in the state. PNNL should monitor those cost trends.

  5. Development of Accident Scenario for Interim Spent Fuel Storage Facility Based on Fukushima Accident

    International Nuclear Information System (INIS)

    700 MTU of spent nuclear fuel is discharged from nuclear fleet every year and spent fuel storage is currently 70.9% full. The on-site wet type spent fuel storage pool of each NPP(nuclear power plants) in Korea will shortly exceed its storage limit. Backdrop, the Korean government has rolled out a plan to construct an interim spent fuel storage facility by 2024. However, the type of interim spent fuel storage facility has not been decided yet in detail. The Fukushima accident has resulted in more stringent requirements for nuclear facilities in case of beyond design basis accidents. Therefore, there has been growing demand for developing scenario on interim storage facility to prepare for beyond design basis accidents and conducting dose assessment based on the scenario to verify the safety of each type of storage

    The flow area and volume are scaled down to 1/49. The ratio of the hydraulic diameter is 1/7. Therefore, SMART-ITL is a large-scale thermalhydraulic test facility with about 45 m height, which is consisted of 10 m underground and 35 m from the ground level. Until now, the management of design data and maintenance of large scale test facilities have been managed based on hard-copy information. Recently, Thermal Hydraulics Safety Research Division (THSRD) at Korea Atomic Energy Research Institute (KAERI) has developed Facility Management System (FMS) based Building Information Modeling (BIM) to manage its design data more effectively for these large scale test facilities of SMART-ITL and ATLAS, and this BIM technology has been applied to SMART-ITL at the first. This study proposed a method of effective management and maintenance of design data applied to the SMART-ITL. That is, a FMS was developed based on the BIM technology for SMART-ITL. Figure 2 shows an overview of FMS development process based on BIM technology. SMART-ITL FMS facilitates its management and maintenance more effectively and accurately by 3- dimensional visualization. It enables the shape information of large scale test facilities to be visualized intuitively in a virtual space, and the efficient maintenance of data and instruments is possible by linking 3D shape information.

    Cellulose is the most abundant renewable and biodegradable material available in nature. Its insoluble character in water as well as common organic and inorganic liquids, however, curtails the wholesome utility. The continuous rise for biodegradable products based on cellulose coupled with its intrinsic ability to form a viable substitute for the petroleum-based materials necessitates the critical need for solubilizing the cellulose. Herein, we demonstrate the feasibility of ZnCl2 solutions, especially the 64-72% concentrations, to dissolve cellulose. FTIR results suggest that Zn(2+) ions promote Zn⋯O3H interactions, which in-turn weaken the intrinsic O3H⋯O5 hydrogen bonds that are responsible for strengthening the cellulose chains. Interestingly, Ca(2+) ions promote interactions among the Zn-cellulose chains leading to the formation of nano fibrils and yield gelling solutions. The tensile strength of the Ca(2+) added Zn-cellulose films increases by around 250% compared to the Zn-cellulose films. Overall, utilization of inorganic salt solutions to solubilize and crosslink cellulose is cost-effective, recyclable and certainly stands out tall among the other available systems. More importantly, the proposed protocol is simple and is a "green" process, and thus its large-scale adaptability is quite feasible. We strongly believe that the outcome opens up a new window of opportunities for cellulose in the biomedical, pharmaceutical, food and non-food applications. PMID:27261751

    Research and development work is currently in progress in France on the feasibility of transmutation of very long-lived radionuclides such as americium, blended with an inert medium such as magnesium oxide and pelletized for irradiation in a fast neutron reactor. The process is primarily designed to produce ceramics for nuclear reactors, but could also be used to produce targets for accelerators. The Actinide Development Laboratory is part of the ATALANTE complex at Marcoule, where the CEA investigates reprocessing, liquid and solid waste treatment and vitrification processes. The laboratory produces radioactive sources; after use, their constituents are recycled, notably through R and D programs requiring such materials. Recovered americium is purified, characterized and transformed for an experiment known as ECRIX, designed to demonstrate the feasibility of fabricating americium-based ceramics and to determine the reactor transmutation coefficients.

    The present building facility management status in China resulted in many problems such as highenergy consumption, failure of automation control, services failure and poor indoor air quality. Based onquestionnaires and interviews to professional engineers and building users, a comprehensive evaluation index system was established on facility management of high-rise office buildings. A Fuzzy AHP based upon hierarchy criteria system was established. A Fuzzy AHP Evaluation Model on Facility Management System was set up ;α-cut analysis was introduced and incorporated with expert knowledge together, which made up the optimism index λ. The fuzzy optimum crisp weight of each criterion was resulted from data-mining. Case investigations were processed in high-rise office buildings in Shenyang. The results illustrated that indoor air quality, thermal comfort and life cycle cost were the most important indexes in the evaluation of Facility Management System of high rise office buildings. Residents in high-rise buildings in Shenyang pay less attention to maintenance management and environment protection. By comparison with the analysis result of Export Choice, Fuzzy AHP-based evaluation model could act as a scientific reference for the establishment of governmental standards in facility management area in building.

  11. Long-term contracts for European gas supply - an empirical analysis of the changing nature of pipeline and LNG-contracts

    International Nuclear Information System (INIS)

    As the structure of the European natural gas market is evolving towards more competition and more diverse market structures than before, the nature of the long-term contracts for European natural gas supply is also undergoing change. Experience from other liberalization processes, such as in the U.S. or the UK, suggests that the importance of long-term contracts diminishes over time, but that they remain an important element of supply. In Europe long-term contracts are still considered as a firm basis for investment and financing of capital-intensive infrastructure with a high degree of asset and relationship-specificity. Literature on institutional economics also suggests that long-term contracts act as a device to overcome the ''hold-up'' problem of relationship-specific investments in infrastructure (Klein, Crawford, and Alchian, 1987; Williamson, 1975, 1985). On the other hand, Hartley and Brito (2002) show that more flexible markets also imply a lower degree of asset specificity, thus requiring less fixed contracts. This paper explores the changing nature of long-term contracts for European natural gas supply, with a particular focus on differences between contracts for pipeline gas and liquefied natural gas (LNG). Traditionally, Europe relied on very long-term contracts for pipeline gas (Russia, Norway, Algeria). More recently, increasing LNG supplies are contemplated as a more flexible source of natural gas: The international LNG market is becoming more flexible, LNG can be sourced from a variety of sellers, and the cost of LNG supplies and infrastructure is coming down rapidly (Jensen, 2004). Thus, the evaluation of investing in LNG infrastructure (and the so bought flexibility and possibility of arbitraging profits) may be higher than committing to fixed/predetermined flows of pipeline gas. We ask whether this is reflected in the observed contracts. The paper is based on standard contract theory (Bolton and Dewatripont, 2005). We apply a microeconomic

  12. Cooperative strategies in the LNG industry: is the rationalisation argument grounded?

    International Nuclear Information System (INIS)

    The authors are commenting the emergence of cooperative strategies between 12 LNG (liquefied natural gas) exporting countries which are part of the Gas Exporting Countries Forum (GECF). In this economic study, they more particularly examine the often evoked scenario of a cooperation only aimed at a logistic rationalisation, which has no impact of LNG prices. Using a simple static model calibrated with data from 2007, they assess the benefit of this cooperation. Numerical results suggest that, in absence of a redistribution policy, this cooperative strategy is likely not to be adopted. Without any redistribution, choosing cooperation would not be rational for some exporters. The issue of sharing this collective benefit is then formulated by using concepts of the cooperative game theory. Several redistribution policies are then studied, including the Shapley value and several concepts based on the nucleolus. The results reveal a relatively restrained choice for the redistribution policy. Among the used methods, only the 'per capita nucleolus', a rather sophisticated one, matches the both desirable properties: to belong to the cooperative game core and a monotony with respect to the aggregate

    The discovery that the neutrino changes flavor as it travels through space has implications for the Standard Model of particle physics (SM)[1]. To know the contribution of neutrinos to the SM, needs precise measurements of the parameters governing the neutrino oscillations. This will require a high intensity beam-based neutrino oscillation facility. The EURONu Design Study will review three currently accepted methods of realizing this facility (the so-called Super-Beams, Beta Beams and Neutrino Factories) and perform a cost assessment that, coupled with the physics performance, will give means to the European research authorities to make a decision on the layout and construction of the future European neutrino oscillation facility. ”Beta Beams” produce collimated pure electron neutrino and antineutrino beams by accelerating beta active ions to high energies and letting them decay in a race-track shaped storage ring. EURONu Beta Beams are based on CERNs infrastructure and the fact that some of the already ...

    1992-02-01

    This document, written for the US Department of Energy, discusses current information and the need for future research on estimating the impacts on wages and property values that could result from people`s perceptions of the risks associated with noxious facilities. Psychometric studies indicate that the US population is averse to living near noxious facilities, nuclear-related facilities in particular. Contingent valuation and hedonic studies find that the net economic impacts of proximity to noxious facilities are generally negative and often substantial. Most of these studies are limited in scope, and none estimate the impacts derived from public perceptions of such facilities. This study examines the mechanisms by which negative public perceptions result in economic impacts reflected in wages and property values. On the basis of these mechanisms, it develops a predictive model of perception-based impacts and identifies the data and methods needed to implement it. The key to predicting perception-based impacts lies in combining psychometric and hedonic methods. The reliability of psychometric measures as indicators of aversive stimuli that precipitate economic impacts can be empirically tested. To test the robustness of the findings, alternative estimation methods an be employed in the hedonic analysis. Contingent valuation methods can confirm the results.

  20. Kalimantan field development hikes gas supply for LNG export

    International Nuclear Information System (INIS)

    This paper reports on the development of Tambora and Tunu gas fields in Kalimantan that have increased available gas supply for the export of liquefied natural gas (LNG) from Indonesia. The demand for LNG is increasing in the energy thirsty Far East market. And Indonesia, the world's largest exporter, is keeping pace by expanding the Bontang liquefaction plant in East Kalimantan. A fifth train, with a capacity of around 2.5 million tons/year, began operating in January 1990. Start-up of a sixth train, of identical capacity, is planned for January 1994. The Bontang plant is operated by PT Badak on behalf of Pertamina, the Indonesian state oil and gas mining company. The feed to the fifth train comes primarily from the first-phase development of Total Indonesie's two gas fields, Tambora and Tunu. The sixth train will be fed by a second-phase development of the Tunu field

    1994-01-01

    Prospects for export of liquified natural gas (LNG) from Alaska's North Slope are assessed. Projected market conditions to 2010 show that new LNG capacity beyond announced expansions will be needed to meet regional demand and that supplies will probably come from outside the region. The estimated delivered costs of likely suppliers show that Alaska North Slope gas will not be competitive. The alternative North Slope gas development strategies of transport and sale to the lower 48 states and use on the North Slope for either enhanced oil recovery or conversion to liquids are examined. The alternative options require delaying development until US gas prices increase, exhaustion of certain North Slope oil fields, or advances occur in gas to liquid fuels conversion technology. ?? 1995.

  2. The Evolving Role of LNG in the Gas Market

    Energy Technology Data Exchange (ETDEWEB)

    De Jong, D.; Van der Linde, C.; Smeenk, T.

    2010-09-15

    The global energy scene is changing rapidly. Producing countries are tightening their grip on the development of their resources, emerging (and other) economies are taking a direct political interest in securing supplies, politics and business are increasingly integrated in international energy deals, and energy is on the political agenda of every government. Compounding this, prices of energy skyrocketed over the four years leading up to August 2008. As a result more gas resources became economical to develop, creating more supply potential than before. However, the severe crisis in international financial markets and national banking systems is now changing this outlook. Prices have come down, and this, combined with the current decline in economic activity, is likely to affect the timing of investment decisions on new pipeline and liquefied natural gas (LNG) projects. The impact on national economies on energy demand, and on the relative position of gas in the energy market could be considerable. At the same time, some consuming countries are also reviewing the environmental effect of their energy policies and the security of their energy supply. Any change in these policies could affect the place of gas in the energy mix. These developments are still unfolding; it is difficult to say at this stage in what ways and to what extent the position of natural gas will change. Nevertheless, some expect further globalization of the gas business, with different market structures, more fragmented value chains, more flexibility in supplies to markets, and shorter term contracts. In this respect, LNG is regarded as the major potential game changer. Indeed the LNG business model has been changing over recent years into one of greater flexibility, promising producers higher rewards, albeit in return for higher risks. More recently the perspective of high rewards in a market hungry for supplies has changed radically, at least for the next few years. A global crisis, lower oil

    Peru's Camisea gas fields hold nearly ninety percent of the country's natural gas reserves. In the 1990s, the government insisted on prioritizing Camisea gas for domestic consumption. The revocation of this policy in the 2000s allowed the private developers to export forty percent of Camisea's proven gas reserves, equivalent to Peru's one third of the total. This USD 3.9 billion LNG export project boasts the largest single foreign direct investment in Peru's history. A major component of the ...

    The risks entailed by an accidental spill of Liquefied Natural Gas (LNG) should be indentified and evaluated, in order to design measures for prevention and mitigation in LNG terminals. For this purpose, simulations are considered a useful tool to study LNG spills and to understand the mechanisms that influence the vapor dispersion. In the present study, the ADREA-HF CFD code is employed to simulate the TEEX1 experiment. The experiment was carried out at the Brayton Fire Training Field, which is affiliated with the Texas A&M University system and involves LNG release and dispersion over water surface in open- obstructed environment. In the simulation the source was modeled as a two-phase jet enabling the prediction of both the vapor dispersion and the liquid pool spreading. The conservation equations for the mixture are solved along with the mass fraction for natural gas. Due to the low prevailing temperatures during the spill ambient humidity condenses and this might affect the vapor dispersion. This effect was examined in this work by solving an additional conservation equation for the water mass fraction. Two different models were tested: the hydrodynamic equilibrium model which assumes kinetic equilibrium between the phases and the non hydrodynamic equilibrium model, in order to assess the effect of slip velocity on the prediction. The slip velocity is defined as the difference between the liquid phase and the vapor phase and is calculated using the algebraic slip model. Constant droplet diameter of three different sizes and a lognormal distribution of the droplet diameter were applied and the results are discussed and compared with the measurements.

    The EU’s FP7 TIARA program for developing accelerator-based facilities has recently demonstrated the unique capabilities of a compact and powerful spallation source for irradiating advanced nuclear materials. The spectrum and intensity of the neutron flux produced in the proposed facility fulfils the requirements of the DEMO fusion reactor for ITER, ADS reactors and also Gen III / IV reactors. Test conditions can be modulated, covering temperature from 400 to 550°C, liquid metal corrosion, cyclical or static stress up to 500 MPa and neutron/proton irradiation damage of up to 25 DPA per annum. The entire “TMIF” facility fits inside a cube 2 metres on a side, and is dimensioned for an accelerator beam power of 100 kW, thus reducing costs and offering great versatility and flexibility.

    The report discusses development of the host-based system to carry out timed measurements and data acquisition for the control of pulsed facilities of the accelerator. We consider modes of timing and allocation of operations of channels and the system node. The time of any working cycle of the pulsed facilities, rate of a data flow and an amount of serviced channels are coordinated with operation characteristics of the system node. Estimations of the readout rate of the data and the waiting time demonstrate the system efficiency. The technique has been developed to provide checking of groups of pulse parameters and control the facilities of the linear accelerator of electrons LUE-200 of the neutron source IREN.

    A facility-based protein crystallization apparatus for microgravity (PCAM) has been constructed and flown on a series of Space Shuttle Missions. The hardware development was undertaken largely because of the many important examples of quality improvements gained from crystal growth in the diffusion-limited environment in space. The concept was based on the adaptation for microgravity of a commonly available crystallization tray to increase sample density, to facilitate co-investigator participation and to improve flight logistics and handling. A co-investigator group representing scientists from industry, academia, and government laboratories has been established. Microgravity applications of the hardware have produced improvements in a number of structure-based crystallographic studies and include examples of enabling research. Additionally, the facility has been used to support fundamental research in protein crystal growth which has delineated factors contributing to the effect of microgravity on the growth and quality of protein crystals.

    A viscous two phase flow model based on the Volume of Fluid ( VOF) method and Immersed Boundary Method (IBM) is used in this research to numerically simulate sloshing problem occurred in the LNG tank (prismatic tank). The whole computational domain is rectangular, and VOF method is used for tracking and updating the free surface, immersed boundary method for boundary processing. A block up coefficient is used for the processing of volume fraction F so that VOF can process the bevel edge boundary. Finally the whole process of the sloshing tank motion, and compare the liquid surface height achieved is achieved by different methods. This study has reference value to this type of sloshing motion.%采用基于Volume of Fluid(VOF)方法和浸入边界法的黏性二相流模型对LNG液舱(棱形液舱)的晃荡问题进行数值模拟.黏性二相流模型采用一套控制方程进行处理.整个计算区域为矩形,自由液面的跟踪和更新采用VOF方法,斜边边界的处理考虑用到浸入边界法,把边界以外的当成是固体,在对VOF中的体积分数F的处理时引入通度系数以适应斜边边界.最后模拟得到液舱横荡的运动过程,对研究这一类型的晃荡运动具有参考价值.

  11. Fixed Base Modal Testing Using the NASA GRC Mechanical Vibration Facility

    The Space Power Facility at NASA's Plum Brook Station houses the world's largest and most powerful space environment simulation facilities, including the Mechanical Vibration Facility (MVF), which offers the world's highest-capacity multi-axis spacecraft shaker system. The MVF was designed to perform sine vibration testing of a Crew Exploration Vehicle (CEV)-class spacecraft with a total mass of 75,000 pounds, center of gravity (cg) height above the table of 284 inches, diameter of 18 feet, and capability of 1.25 gravity units peak acceleration in the vertical and 1.0 gravity units peak acceleration in the lateral directions. The MVF is a six-degree-of-freedom, servo-hydraulic, sinusoidal base-shake vibration system that has the advantage of being able to perform single-axis sine vibration testing of large structures in the vertical and two lateral axes without the need to reconfigure the test article for each axis. This paper discusses efforts to extend the MVF's capabilities so that it can also be used to determine fixed base modes of its test article without the need for an expensive test-correlated facility simulation.

  15. GTL or LNG: Which is the best way to monetize "stranded" natural gas?

    Institute of Scientific and Technical Information of China (English)

    Dong Lichun; Wei Shun'an; Tan Shiyu; Zhang Hongjing

    2008-01-01

    A large portion of world's natural gas reserves are "stranded" resources, the drive to monetize these resources leads to the development of gas-to-liquids (GTL) and liquefied natural gas (LNG) technologies. LNG has the advantage of having been developed for the past 40 years and having an excellent safety record. GTL on the other hand is another option with substantial benefits, but its development stage and commercial viability are far behind LNG. This paper presents a techno-economic comparison of GTL with LNG, including technical development, plant efficiency, market potential for the products, and capital cost for the infrastructure. The aim is to give an overall view on both LNG and GTL and provide a perspective on the profitability of these two technologies.

    The operation to Liquefied Natural Gas (LNG) is innovative for the PETROBRAS System. PETROBRAS Transporte - TRANSPETRO will operate two LNG flexible terminals. In accordance with the health, safety and environmental policy - training, education and awareness action plans were formulated by TRANSPETRO to assure the operational safety for the activity. Part of this action plan includes the training of LNG spill control and fire suppression. The training was carried out in 20 hours and divided into two parts: theoretical and practice. In the practice part, 3.000 gallons of LNG were unloaded and the students could verify the behaviour of the LNG and the effectiveness of the resources available for the emergency control. The knowledge was introduced in the company to create specific procedures, local emergency plans and develop internal instructors. (author)

  17. Prospects for fluorescence based imaging/visualization of hydrodynamic systems on the National Ignition Facility

    International Nuclear Information System (INIS)

    The next generation of large, high power lasers, such as the National Ignition Facility in the U.S., Laser Mega Joule in France or Helen Successor in the United Kingdom offers the prospect of x-ray fluorescence based diagnosis of hydrodynamic experiments. We discuss two promising techniques for pumping this fluorescence. One is to use a large fraction of these facilities close-quote high power to efficiently make multi-kilovolt x rays which, in turn, causes dopants placed in experimental packages to fluoresce. The second technique is to use the sizable multi-kilovolt photon background that we expect to be present in many hohlraum based experiments, while the driving laser is on, to pump x-ray fluorescence. Here, the fluorescing medium could be a dopant in an experimental package or, possibly, a relatively thick slab of material in the hohlraum wall which could serve as a backlighter. copyright 1999 American Institute of Physics

    One of the basic facilities at the Joint Institute for Nuclear Research (JINR) in Dubna is the 6 A GeV Nuclotron, which has replaced the old weak focusing 10-GeV proton accelerator Synchrophasotron. The first relativistic nuclear beams with the energy of 4.2 A GeV were obtained at the Synchrophasotron in 1971. Since that time, relativistic nuclear physics has been one of the main directions of the JINR research program. In the coming years, the new JINR flagship program assumes the experimental study of hot and dense strongly interacting QCD matter at the new JINR facility. This goal is proposed to be reached by (i) development of the existing Nuclotron accelerator facility as a basis for generation of intense beams over atomic mass range from protons to uranium and light polarized ions, (ii) design and construction of the Nuclotron-based heavy Ion Collider fAcility (NICA) with the maximum nucleon-nucleon center-of-mass collision energy of √ s NN = 9 GeV and averaged luminosity 1027 cm-2 s-1, and (iii) design and construction of the Multipurpose Particle Detector (MPD) at intersecting beams. Realization of the project will lead to unique conditions for research activity of the world community. The NICA energy region is of major interest because the highest nuclear (baryonic) density under laboratory conditions can be reached there. Generation of intense polarized light nuclear beams aimed at investigation of polarization phenomena at the Nuclotron is foreseen.

    Full Text Available Facility management (FM has become an important topic in research on the operation and maintenance phase. Managing the work of FM effectively is extremely difficult owing to the variety of environments. One of the difficulties is the performance of two-dimensional (2D graphics when depicting facilities. Building information modeling (BIM uses precise geometry and relevant data to support the facilities depicted in three-dimensional (3D object-oriented computer-aided design (CAD. This paper proposes a new and practical methodology with application to FM that uses an integrated 2D barcode and the BIM approach. Using 2D barcode and BIM technologies, this study proposes a mobile automated BIM-based facility management (BIMFM system for FM staff in the operation and maintenance phase. The mobile automated BIMFM system is then applied in a selected case study of a commercial building project in Taiwan to verify the proposed methodology and demonstrate its effectiveness in FM practice. The combined results demonstrate that a BIMFM-like system can be an effective mobile automated FM tool. The advantage of the mobile automated BIMFM system lies not only in improving FM work efficiency for the FM staff but also in facilitating FM updates and transfers in the BIM environment.

  2. The role of Liquefied Natural Gas (LNG) in the European gas market

    International Nuclear Information System (INIS)

    The purpose of this paper is to discuss the role that Liquefied Natural Gas (LNG) might play in the future EU gas market. LNG imports are not likely to have a place in the Netherlands soon, but they could make an important contribution to the volume and diversity of Europe's gas supplies. An important characteristic of LNG is its inherently high costs, throughout the whole chain, from the wellhead to the market. These costs are considerably higher than the costs of bringing oil to the market. Cost considerations, in combination with the rigidity of the gas market, have led to the use of long-term contracts as a basis for the business, as is the case for the long haul pipeline gas business. Costs have come down considerably and further cost reductions are 'in the pipeline'. While this does not alter the fundamentals of the business it has nonetheless helped to extend the reach of LNG. LNG from the Middle East to Europe has now become economically feasible. The high gas prices of recent years have further fuelled the expansion of the LNG business. Supported by a rapidly growing global economy at the turn of this century, many prospects are under development. The positive economic outlook has seen more speculative positioning in every segment of the LNG chain, while more vertical integration has been industry's response to market liberalisation. The more recent slowdown of the market economies has created a surplus of LNG, which is finding its way onto the markets through short-term and spot transactions. The short-term business will grow over the next few years as more LNG and shipping capacity comes on-stream. However, given underlying high costs and limited flexibility, it should be expected that new projects, currently under consideration, will only be developed on the basis of long-term contracts, thus returning to a balance between supply and demand. For these same reasons, LNG will not likely develop the same the liquidity as that of the oil market. The global

  3. Project for the development of the linac based NCT facility in University of Tsukuba

    International Nuclear Information System (INIS)

    A project team headed by University of Tsukuba launched the development of a new accelerator based BNCT facility. In the project, we have adopted Radio-Frequency Quadrupole (RFQ)+Drift Tube Linac (DTL) type linac as proton accelerators. Proton energy generated from the linac was set to 8 MeV and average current was 10 mA. The linac tube has been constructed by Mitsubishi Heavy Industry Co. For neutron generator device, beryllium is selected as neutron target material; high intensity neutrons are generated by the reaction with beryllium and the 80 kW proton beam. Our team chose beryllium as the neutron target material. At present beryllium target system is being designed with Monte-Carlo estimations and heat analysis with ANSYS. The neutron generator consists of moderator, collimator and shielding. It is being designed together with the beryllium target system. We also acquired a building in Tokai village; the building has been renovated for use as BNCT treatment facility. It is noteworthy that the linac tube had been installed in the facility in September 2012. In BNCT procedure, several medical devices are required for BNCT treatment such as treatment planning system, patient positioning device and radiation monitors. Thus these are being developed together with the linac based neutron source. For treatment planning system, we are now developing a new multi-modal Monte-Carlo treatment planning system based on JCDS. The system allows us to perform dose estimation for BNCT as well as particle radiotherapy and X-ray therapy. And the patient positioning device can navigate a patient to irradiation position quickly and properly. Furthermore the device is able to monitor movement of the patient's position during irradiation. - Highlights: • A project team headed by University of Tsukuba launched a development of new accelerator based BNCT facility. • The project adopted an 8 MeV RFQ+DTL type linac as proton accelerator. • The linac tube is completed and

    This study set the pyroprocess facility at an engineering scale as a cost object, and presented the cost consumed during the unit processes of the pyroprocess. For the cost calculation, the activity based costing (ABC) method was used instead of the engineering cost estimation method, which calculates the cost based on the conceptual design of the pyroprocess facility. The calculation results demonstrate that the pyroprocess facility's unit process cost is $194/kgHM for pretreatment, $298/kgHM for electrochemical reduction, $226/kgHM for electrorefining, and $299/kgHM for electrowinning. An analysis demonstrated that the share of each unit process cost among the total pyroprocess cost is as follows: 19% for pretreatment, 29% for electrochemical reduction, 22% for electrorefining, and 30% for electrowinning. The total unit cost of the pyroprocess was calculated at $1,017/kgHM. In the end, electrochemical reduction and the electrowinning process took up most of the cost, and the individual costs for these two processes was found to be similar. This is because significant raw material cost is required for the electrochemical reduction process, which uses platinum as an anode electrode. In addition, significant raw material costs are required, such as for Li3PO4, which is used a lot during the salt purification process.

    A major barrier to successful integration of acute care into health systems is the lack of consensus on the essential components of emergency care within resource-limited environments. The 2013 African Federation of Emergency Medicine Consensus Conference was convened to address the growing need for practical solutions to further implementation of emergency care in sub-Saharan Africa. Over 40 participants from 15 countries participated in the working group that focused on emergency care delivery at health facilities. Using the well-established approach developed in the WHO's Monitoring Emergency Obstetric Care, the workgroup identified the essential services delivered-signal functions-associated with each emergency care sentinel condition. Levels of emergency care were assigned based on the expected capacity of the facility to perform signal functions, and the necessary human, equipment and infrastructure resources identified. These consensus-based recommendations provide the foundation for objective facility capacity assessment in developing emergency health systems that can bolster strategic planning as well as facilitate monitoring and evaluation of service delivery.

  9. Accident Management ampersand Risk-Based Compliance With 40 CFR 68 for Chemical Process Facilities

    International Nuclear Information System (INIS)

    A risk-based logic model is suggested as an appropriate basis for better predicting accident progression and ensuing source terms to the environment from process upset conditions in complex chemical process facilities. Under emergency conditions, decision-makers may use the Accident Progression Event Tree approach to identify the best countermeasure for minimizing deleterious consequences to receptor groups before the atmospheric release has initiated. It is concluded that the chemical process industry may use this methodology as a supplemental information provider to better comply with the Environmental Protection Agency's proposed 40 CFR 68 Risk Management Program rule. An illustration using a benzene-nitric acid potential interaction demonstrates the value of the logic process. The identification of worst-case releases and planning for emergency response are improved through these methods, at minimum. It also provides a systematic basis for prioritizing facility modifications to correct vulnerabilities

    As an energy source,liquefied natural gas (LNG) has the advantages of clean and efficient. The vaporization of LNG releases a large number of cold energy,which has great economic value and environmental value. But it is a common problem that LNG cold energy utilization rate is low. This paper presents various ways of the LNG cold energy utilization,compares the advantages and disadvantages and cooling energy requirements among them,and dicusses the prospects for their utilization and environmental values. LNG cold energy utilization technology development and the research progress are also introduced. To solve the problem of low utilization rate,suggestions of taking advantage of the principle of temperature counterpart and cascade utilization,developing accumulation and cold energy storage device as well as developing new refrigerating medium,are proposed. The choice of cold energy projects should be based on the availability of local conditions and new forms of cold energy utilization need to be developed.%液化天然气(LNG)作为一种清洁、高效的优质能源,其汽化释放的大量冷量具有极大的经济价值及环保价值,但却存在 LNG冷能利用率不高的普遍问题。本文阐述了 LNG 冷能利用的各种方式,比较了各种方式的优缺点及冷能需求,分析了其利用前景及环保价值。介绍了国内外液化天然气冷能利用技术的开发与研究进展,指出了其冷能利用率普遍不高的原因。在此基础上强调了LNG冷能“温度对口,梯级利用”原则的重要性,开发蓄积和储存冷能的装置以及研发新型载冷剂的迫切性,并提出因地制宜选择冷能利用项目,拓展新的冷能利用形式。

    During this reporting period, kickoff and planning meetings were held. Subcontracted experimental and modeling tasks were defined. Efforts to address the numerical stability problems that hamper FEM3A's applicability to low wind speed, stable atmospheric conditions were initiated. A detailed review of FEM3A code and its execution, required for development of an accessible user interface, was also begun. A one-day workshop on LNG safety models has been scheduled for September 2004. The goals of this project are to develop a national focal point for LNG safety research and technical dissemination and to develop the FEM3A dispersion model for application to general scenarios involving dispersion problems with obstacle and terrain features of realistic complexity. During this reporting period, the objectives and scope of the project and its constituent tasks were discussed at a project kickoff meeting in Morgantown. Details of the subcontracted experimental and modeling tasks were further defined at a separate meeting at the University of Arkansas. Researchers at the university have begun to modify the turbulence closure model used in FEM3A to insure numerical stability during simulation of low-wind-speed, stable atmospheric conditions. The university's wind tunnel is being prepared for upcoming experimental studies. GTI has begun a detailed review of the FEM3A code and its execution that will provide guidance during development of an accessible user interface. Plans were made for a one day workshop on LNG safety models that will be held at the end of September and will provide an introduction to currently available and pending software tools.

    Full Text Available Abstract Background High throughput gene expression profiling (GEP is becoming a routine technique in life science laboratories. With experimental designs that repeatedly span thousands of genes and hundreds of samples, relying on a dedicated database infrastructure is no longer an option. GEP technology is a fast moving target, with new approaches constantly broadening the field diversity. This technology heterogeneity, compounded by the informatics complexity of GEP databases, means that software developments have so far focused on mainstream techniques, leaving less typical yet established techniques such as Nylon microarrays at best partially supported. Results MAF (MicroArray Facility is the laboratory database system we have developed for managing the design, production and hybridization of spotted microarrays. Although it can support the widely used glass microarrays and oligo-chips, MAF was designed with the specific idiosyncrasies of Nylon based microarrays in mind. Notably single channel radioactive probes, microarray stripping and reuse, vector control hybridizations and spike-in controls are all natively supported by the software suite. MicroArray Facility is MIAME supportive and dynamically provides feedback on missing annotations to help users estimate effective MIAME compliance. Genomic data such as clone identifiers and gene symbols are also directly annotated by MAF software using standard public resources. The MAGE-ML data format is implemented for full data export. Journalized database operations (audit tracking, data anonymization, material traceability and user/project level confidentiality policies are also managed by MAF. Conclusion MicroArray Facility is a complete data management system for microarray producers and end-users. Particular care has been devoted to adequately model Nylon based microarrays. The MAF system, developed and implemented in both private and academic environments, has proved a robust solution for

    An important option to transport the gas is to convert it into liquid natural gas (LNG) and convey it using insulated LNG tankers. At receiving terminals, the LNG is offloaded into storage tanks and then pumped at the required pressure and vaporized for final transmission to the pipeline. The LNG production process consumes a considerable amount of energy, while the cold availability, as also known as cold energy, has been stored in LNG. At a receiving terminal, LNG needs to be evaporated into gas at environmental temperature before fed into the gas distribution system. Seawater is commonly used for the regasification process of the LNG. In the present paper, after a general analysis of the perspectives of the various thermodynamic schemes proposed for power production from the regasification, a detailed analysis of enhanced direct expansion system is carried out in order to identify the upper level of the energy that can be recovered. The analysis outlines that power production typical of optimized ORC plant configurations (120 kJ/kg) can be obtained with direct expansion solutions.

    2010-08-01

    Full Text Available This paper focuses on the effect of pressure and heat leakages on Boil-off Gas (BOG in Liquefied Natural Gas (LNG tanks. The Lee-Kesler-Plocker (LKP and the Starling modified Benedict-Webb-Rubin (BWRS empirical models were used to simulate the compressibility factor, enthalpy and hence heat leakage at various pressures to determine the factors that affect the BOG in typical LNG tanks of different capacities. Using a case study data the heat leakage of 140,000kl, 160,00kl, 180,000kl and 200,000kl LNG tanks were analyzed using the LKP and BWRS models. The heat leakage of LNG tanks depends on the structure of tanks, and the small tanks lose heatto the environment due to their large surface area to volume ratio. As the operation pressure was dropped to 200mbar, all four of the LNG tanks’ BOG levels reached 0.05vol%/day. In order to satisfy the BOG design requirement, the operating pressure of the four large LNG tanks in the case study was maintained above 200mbar. Thus, the operating pressure impacts BOG on LNG tanks, but this effect is limited under the extreme high operation pressure. An attempt was made to determine the relationship between the compositions of LNGand BOG; one been combustible and the other non-combustible gases. The main component of combustible gas was methane, and nitrogen was of non-combustible gases. The relationship between BOG and methane compositions was that, as the methane fraction increases in the LNG, the BOG volume also increases. In general, results showed a direct correlation between BOG and operating pressure. The study also found that larger LNG tanks have less BOG; however as the operation pressure is increased the differences in the quantity of BOGamong the four tanks decreased.

    This work aims analyze the constraints to the introduction of LNG in the Brazilian energy matrix. Therefore, considers the current regulatory framework and the investments recently made by PETROBRAS to acquire LNG in the international market in order to supply power plants in the country. In order to assess the current status of the LNG plants in the electricity sector, factors are analyzed in terms of the natural gas industry and electric power industry, such as: storage, LNG contracts, operating dispatch, LNG plants pricing and operational flexibility. Despite the increase in LNG international trade and the prospect of using this product in Brazil, there are some challenges for the effective use of LNG plants by Brazilian electric sector. Some of the challenges are the need to review the methodology of calculating the cost benefit of LNG power plants. Another important challenge is to examine the use of underground storage and its influence in the operating dispatch of LNG plants. (author)

    Facility maintenance management (FMM) has become an important topic for research on the operation phase of the construction life cycle. Managing FMM effectively is extremely difficult owing to various factors and environments. One of the difficulties is the performance of 2D graphics when depicting maintenance service. Building information modeling (BIM) uses precise geometry and relevant data to support the maintenance service of facilities depicted in 3D object-oriented CAD. This paper proposes a new and practical methodology with application to FMM using BIM technology. Using BIM technology, this study proposes a BIM-based facility maintenance management (BIMFMM) system for maintenance staff in the operation and maintenance phase. The BIMFMM system is then applied in selected case study of a commercial building project in Taiwan to verify the proposed methodology and demonstrate its effectiveness in FMM practice. Using the BIMFMM system, maintenance staff can access and review 3D BIM models for updating related maintenance records in a digital format. Moreover, this study presents a generic system architecture and its implementation. The combined results demonstrate that a BIMFMM-like system can be an effective visual FMM tool. PMID:24227995

  20. Feasibility study for a biomedical experimental facility based on LEIR at CERN

    International Nuclear Information System (INIS)

    In light of the recent European developments in ion beam therapy, there is a strong interest from the biomedical research community to have more access to clinically relevant beams. Beamtime for pre-clinical studies is currently very limited and a new dedicated facility would allow extensive research into the radiobiological mechanisms of ion beam radiation and the development of more refined techniques of dosimetry and imaging. This basic research would support the current clinical efforts of the new treatment centres in Europe (for example HIT, CNAO and MedAustron). This paper presents first investigations on the feasibility of an experimental biomedical facility based on the CERN Low Energy Ion Ring LEIR accelerator. Such a new facility could provide beams of light ions (from protons to neon ions) in a collaborative and cost-effective way, since it would rely partly on CERN's competences and infrastructure. The main technical challenges linked to the implementation of a slow extraction scheme for LEIR and to the design of the experimental beamlines are described and first solutions presented. These include introducing new extraction septa into one of the straight sections of the synchrotron, changing the power supply configuration of the magnets, and designing a new horizontal beamline suitable for clinical beam energies, and a low-energy vertical beamline for particular radiobiological experiments.

    Neutron generators based on inertial electrostatic confinement fusion were considered for the design of a neutron irradiation facility for explanted organ Boron Neutron Capture Therapy (BNCT) that could be installed in a health care center as well as in research areas. The chosen facility configuration is "irradiation chamber", a ~20×20×40 cm(3) cavity near or in the center of the facility geometry where samples to be irradiated can be placed. Neutron flux calculations were performed to study different manners for improving scattering processes and, consequently, optimize neutron flux in the irradiation position. Flux distributions were assessed through numerical simulations of several models implemented in MCNP5 particle transport code. Simulation results provided a wide spectrum of combinations of net fluxes and energy spectrum distributions. Among them one can find a group that can provide thermal neutron fluxes per unit of production rate in a range from 4.1·10(-4) cm(-2) to 1.6·10(-3) cm(-2) with epithermal-to-thermal ratios between 0.3% and 13% and fast-to-thermal ratios between 0.01% to 8%. Neutron generators could be built to provide more than 10(10) n s(-1) and, consequently, with an arrangement of several generators appropriate enough neutron fluxes could be obtained that would be useful for several BNCT-related irradiations and, eventually, for clinical practice.

    Full Text Available Facility maintenance management (FMM has become an important topic for research on the operation phase of the construction life cycle. Managing FMM effectively is extremely difficult owing to various factors and environments. One of the difficulties is the performance of 2D graphics when depicting maintenance service. Building information modeling (BIM uses precise geometry and relevant data to support the maintenance service of facilities depicted in 3D object-oriented CAD. This paper proposes a new and practical methodology with application to FMM using BIM technology. Using BIM technology, this study proposes a BIM-based facility maintenance management (BIMFMM system for maintenance staff in the operation and maintenance phase. The BIMFMM system is then applied in selected case study of a commercial building project in Taiwan to verify the proposed methodology and demonstrate its effectiveness in FMM practice. Using the BIMFMM system, maintenance staff can access and review 3D BIM models for updating related maintenance records in a digital format. Moreover, this study presents a generic system architecture and its implementation. The combined results demonstrate that a BIMFMM-like system can be an effective visual FMM tool.

    In light of the recent European developments in ion beam therapy, there is a strong interest from the biomedical research community to have more access to clinically relevant beams. Beamtime for pre-clinical studies is currently very limited and a new dedicated facility would allow extensive research into the radiobiological mechanisms of ion beam radiation and the development of more refined techniques of dosimetry and imaging. This basic research would support the current clinical efforts of the new treatment centres in Europe (for example HIT, CNAO and MedAustron). This paper presents first investigations on the feasibility of an experimental biomedical facility based on the CERN Low Energy Ion Ring LEIR accelerator. Such a new facility could provide beams of light ions (from protons to neon ions) in a collaborative and cost-effective way, since it would rely partly on CERN's competences and infrastructure. The main technical challenges linked to the implementation of a slow extraction scheme for LEIR and to the design of the experimental beamlines are described and first solutions presented. These include introducing new extraction septa into one of the straight sections of the synchrotron, changing the power supply configuration of the magnets, and designing a new horizontal beamline suitable for clinical beam energies, and a low-energy vertical beamline for particular radiobiological experiments.

    Nanonization strategies have been used to enhance the oral availability of numerous drugs that are poorly soluble in water. Exploring a facile nanonization strategy with highly practical potential is an attractive focus. Here, we report a novel facile nanoaggregation strategy for constructing drug nanoparticles of poorly soluble drugs with pH-dependent solubility by utilizing acid-base neutralization in aqueous solution, thus facilitating the exploration of nanonization in oral delivery for general applicability. We demonstrate that hydrophobic itraconazole dissolved in acid solution formed a growing core and aggregated into nanoparticles in the presence of stabilizers. The nanoparticles, with an average diameter of 279.3 nm and polydispersity index of 0.116, showed a higher dissolution rate when compared with the marketed formulation; the average dissolution was about 91.3%. The in vivo pharmacokinetic studies revealed that the nanoparticles had a rapid absorption and enhanced oral availability. The diet state also showed insignificant impact on the absorption of itraconazole from nanoparticles. This nanoaggregation strategy is a promising nanonization method with a facile process and avoidance of toxic organic solvents for oral delivery of poorly soluble drugs with pH-dependent solubility and reveals a highly practical potential in the pharmaceutical and chemical industries.

    Spain is a country with six LNG terminals in operation and three more scheduled for 2011. At the same time an increasing number of LNG tanks are under construction to compensate the Spanish lack of underground storage. A method for evaluating the daily boil off generated is presented in this paper. This method is applied to evaluate the increase of BOG to be handle by LNG terminals in 2016, studying the best commercially available solution to be installed. Finally, as a solution to tackle with the BOG a cogeneration plant is suggested. This option will reduce terminal's operational costs increasing its availability. (author)

    A project team headed by University of Tsukuba launched the development of a new accelerator based BNCT facility. In the project, we have adopted Radio-Frequency Quadrupole (RFQ)+Drift Tube Linac (DTL) type linac as proton accelerators. Proton energy generated from the linac was set to 8MeV and average current was 10mA. The linac tube has been constructed by Mitsubishi Heavy Industry Co. For neutron generator device, beryllium is selected as neutron target material; high intensity neutrons are generated by the reaction with beryllium and the 80kW proton beam. Our team chose beryllium as the neutron target material. At present beryllium target system is being designed with Monte-Carlo estimations and heat analysis with ANSYS. The neutron generator consists of moderator, collimator and shielding. It is being designed together with the beryllium target system. We also acquired a building in Tokai village; the building has been renovated for use as BNCT treatment facility. It is noteworthy that the linac tube had been installed in the facility in September 2012. In BNCT procedure, several medical devices are required for BNCT treatment such as treatment planning system, patient positioning device and radiation monitors. Thus these are being developed together with the linac based neutron source. For treatment planning system, we are now developing a new multi-modal Monte-Carlo treatment planning system based on JCDS. The system allows us to perform dose estimation for BNCT as well as particle radiotherapy and X-ray therapy. And the patient positioning device can navigate a patient to irradiation position quickly and properly. Furthermore the device is able to monitor movement of the patient׳s position during irradiation.

Photosynthesis intensity, photosynthetic productivity and growth morphology as well as chlorophyll and phytohormone concentrations were investigated in radish and lettuce grown in phytotron chambers under the LED-based illuminators and under high-pressure sodium (HPS) lamps with an equivalent photon flux density. Advantages of the high-power LED-based illuminators over conventional HPS lamps, applicability of AlGaInP LEDs for photosynthesis and control of plant growth by circadian manipulation of a relatively weak far-red component were demonstrated.

    This study has provided an initial picture of where the most interesting ports and areas available for future expansion of a maritime infrastructure for LNG. On the basis of supplying vessels with LNG as fuel, from a long term perspective, we recommend locating LNG terminals in or near major ports and around the big ship routes. Given the current age distribution of ships operating waters of the Baltic Sea, almost 20% of the vessels are 30-40 years old and likely to be replaced by 2015 - 2020. Thus, there is a potential for newly built ships will be equipped with LNG operation. Selected criteria s; Size of the LNG terminal and hence the need for the size of the fairway and the area of land. Proximity to traffic routes with much ship traffic. Proximity to the major port. Proximity to consumers on the land side. On the basis of selected criteria and analyzed for possible location of the terminal it can be noted that a number of Swedish ports are found suitable. For example, ports of Sundsvall, Gothenburg and Helsingborg has been identified as suitable, but with different starting point and different types and sizes of terminals possible.

    International Nuclear Information System (INIS)

    An overview is presented of the supply and demand outlook for liquefied natural gas (LNG) in the far east, and the basic elements of an LNG supply project in Japan. Power generation is the primary market for LNG in the far east, due to a preference for energy supply diversity, large undeveloped gas resources, drastic improvements in power generation technology, and environmental advantages of natural gas. India and mainland China represent huge potential markets, and projects are under discussion to bring gas by pipeline from Iran or Qatar to both Pakistan or India. The economics of LNG plant development in Japan, including large ($4 billion for field and plant development) capital costs, long-term contracts, government involvement, and gas prices are discussed. Falling yen/dollar exchange rates have substantially bettered the Japanese economy in terms of gas prices. 11 figs., 2 tabs

  1. Boil-off gas vapors are recovered by reliquefaction in LNG

    Energy Technology Data Exchange (ETDEWEB)

    Levay, M.; Petit, P.; Paradowski, H.

    1986-02-24

    Although great care is taken to prevent heat leaks into cryogenic equipment in LNG terminals, boil-off vapors evolve from LNG stored at thermodynamic equilibrium. The quantities of boil-off vapors may be quite considerable. They account for about 1% of the total gas quantity received and sent out at the monitor-de-bretagne LNG terminal of Gaz de France. A novel process has significantly cut boil-off vapor handling costs. It is free of technical problems which would arise from local utilization of the gas and makes boil-off recovery possible under optimum conditions. In addition, the process shows an excellent degree of reliability. Boil-off vapors have a lower heating value than the stored LNG. However, since they mainly consist of methane, their economic usefulness makes vapor recovery necessary. This boil-off gas, with widely fluctuating quantities and qualities, cannot be readily used locally. The vapors must be sent out into the grid.

  2. A recirculating linac-based facility for ultrafast X-ray science

    International Nuclear Information System (INIS)

    We present an updated design for a proposed source of ultra-fast synchrotron radiation pulses based on a recirculating superconducting linac, in particular the incorporation of EUV and soft x-ray production. The project has been named LUX - Linac-based Ultrafast X-ray facility. The source produces intense x-ray pulses with duration of 10-100 fs at a 10 kHz repetition rate, with synchronization of 10 s fs, optimized for the study of ultra-fast dynamics. The photon range covers the EUV to hard x-ray spectrum by use of seeded harmonic generation in undulators, and a specialized technique for ultra-short-pulse photon production in the 1-10 keV range. High-brightness rf photocathodes produce electron bunches which are optimized either for coherent emission in free-electron lasers, or to provide a large x/y emittance ration and small vertical emittance which allows for manipulation to produce short-pulse hard x-rays. An injector linac accelerates the beam to 120 MeV, and is followed by four passes through a 600-720 MeV recirculating linac. We outline the major technical components of the proposed facility

  3. GIS based location optimization for mobile produced water treatment facilities in shale gas operations

    Science.gov (United States)

    Kitwadkar, Amol Hanmant

    Over 60% of the nation's total energy is supplied by oil and natural gas together and this demand for energy will continue to grow in the future (Radler et al. 2012). The growing demand is pushing the exploration and exploitation of onshore oil and natural gas reservoirs. Hydraulic fracturing has proven to not only create jobs and achieve economic growth, but also has proven to exert a lot of stress on natural resources---such as water. As water is one of the most important factors in the world of hydraulic fracturing, proper fluids management during the development of a field of operation is perhaps the key element to address a lot of these issues. Almost 30% of the water used during hydraulic fracturing comes out of the well in the form of flowback water during the first month after the well is fractured (Bai et. al. 2012). Handling this large amount of water coming out of the newly fractured wells is one of the major issues as the volume of the water after this period drops off and remains constant for a long time (Bai et. al. 2012) and permanent facilities can be constructed to take care of the water over a longer period. This paper illustrates development of a GIS based tool for optimizing the location of a mobile produced water treatment facility while development is still occurring. A methodology was developed based on a multi criteria decision analysis (MCDA) to optimize the location of the mobile treatment facilities. The criteria for MCDA include well density, ease of access (from roads considering truck hauls) and piping minimization if piping is used and water volume produced. The area of study is 72 square miles east of Greeley, CO in the Wattenberg Field in northeastern Colorado that will be developed for oil and gas production starting in the year 2014. A quarterly analysis is done so that we can observe the effect of future development plans and current circumstances on the location as we move from quarter to quarter. This will help the operators to

    We present facile strategies for the fabrication of two types of microfluidic devices made of hydrogels using the natural biopolymers, alginate, and gelatin as substrates. The processes presented include the molding-based preparation of hydrogel plates and their chemical bonding. To prepare calcium-alginate hydrogel microdevices, we suppressed the volume shrinkage of the alginate solution during gelation using propylene glycol alginate in the precursor solution along with sodium alginate. In addition, a chemical bonding method was developed using a polyelectrolyte membrane of poly-L-lysine as the electrostatic glue. To prepare gelatin-based microdevices, we used microbial transglutaminase to bond hydrogel plates chemically and to cross-link and stabilize the hydrogel matrix. As an application, mammalian cells (fibroblasts and vascular endothelial cells) were cultivated on the microchannel surface to form three-dimensional capillary-embedding tissue models for biological research and tissue engineering.

    Full Text Available Background: Rationalize of drug use in societies is one of the main responsibilities of health policy makers. In our country irrational use of dugs has increased in the recent years, for example one study in 1998 has shown that average number of medicines per prescription was 3.6, percentage of prescriptions containing antibiotics was 43% and percentage of prescriptions containing Injections was 39%. One of the best tools for evaluation of drug use is the WHO guideline for calculating prescribing indicators. In this study, we had an assessment about prescribing patterns in South of Tehran, Islamshahr and Rey Health Centers.Methods: In order to evaluating prescribing indicators in Tehran University of Medical Sciences region 35 facilities which had pharmacy were selected according to WHO gridline and 4190 prescription from these facilities were studied. Indicators were calculated according to formulas has explained in article. Results: The average number of drug per prescription was 2.58, percentage of drug prescribed by generic name: 99.8%, percentage of encounters prescribed Antibiotics: 62.39% percentage of encounters prescribed Injection: 28.96% & the percentage of drugs prescribed from PHC formulary 99.46%. These findings were almost similar in the three Health Centers.Conclusions: Health facilities are one of the most important bases to improve rational use of Drugs and general practitioners are the major chain in RUD cycle. Results show that we need to design intervention especially educational interventions to improve two WHO prescribing indicators, percentage of encounters prescribed Antibiotics & Injections in this region. For reaching this goals we need to design educational programs for physicians, pharmacists and people too. These educations can be as workshops, seminars, conferences or printed materials such as books, leaflets and etc.

    Objective Presenting the results of 5 years of implementing health facility-based maternal death audits in Rwanda, showing maternal death classification, identification of substandard (care) factors that have contributed to death, and conclusive recommendations for quality improvements in maternal and obstetric care. Design Nationwide facility-based retrospective cohort study. Settings All cases of maternal death audited by district hospital-based audit teams between January 2009 and December 2013 were reviewed. Maternal deaths that were not subjected to a local audit are not part of the cohort. Population 987 audited cases of maternal death. Main outcome measures Characteristics of deceased women, timing of onset of complications, place of death, parity, gravida, antenatal clinic attendance, reported cause of death, service factors and individual factors identified by committees as having contributed to death, and recommendations made by audit teams. Results 987 cases were audited, representing 93.1% of all maternal deaths reported through the national health management information system over the 5-year period. Almost 3 quarters of the deaths (71.6%) occurred at district hospitals. In 44.9% of these cases, death occurred in the post-partum period. Seventy per cent were due to direct causes, with post-partum haemorrhage as the leading cause (22.7%), followed by obstructed labour (12.3%). Indirect causes accounted for 25.7% of maternal deaths, with malaria as the leading cause (7.5%). Health system failures were identified as the main responsible factor for the majority of cases (61.0%); in 30.3% of the cases, the main factor was patient or community related. Conclusions The facility-based maternal death audit approach has helped hospital teams to identify direct and indirect causes of death, and their contributing factors, and to make recommendations for actions that would reduce the risk of reoccurrence. Rwanda can complement maternal death audits with other

    Federal safety regulations require the use of validated consequence models to determine the vapor cloud dispersion exclusion zones for accidental liquefied natural gas (LNG) releases. One tool that is being developed in industry for exclusion zone determination and LNG vapor dispersion modeling is computational fluid dynamics (CFD). This paper uses the ANSYS CFX CFD code to model LNG vapor dispersion in the atmosphere. Discussed are important parameters that are essential inputs to the ANSYS CFX simulations, including the atmospheric conditions, LNG evaporation rate and pool area, turbulence in the source term, ground surface temperature and roughness height, and effects of obstacles. A sensitivity analysis was conducted to illustrate uncertainties in the simulation results arising from the mesh size and source term turbulence intensity. In addition, a set of medium-scale LNG spill tests were performed at the Brayton Fire Training Field to collect data for validating the ANSYS CFX prediction results. A comparison of test data with simulation results demonstrated that CFX was able to describe the dense gas behavior of LNG vapor cloud, and its prediction results of downwind gas concentrations close to ground level were in approximate agreement with the test data.

  9. Performance of grid-tied PV facilities based on real data in Spain: Central inverter versus string system

    International Nuclear Information System (INIS)

    Highlights: • The operation of two grid-tied PV facilities over a two-year period is presented. • The central inverter system is compared to the string inverter system. • A procedure based on a small number of easily obtained parameters is used. • The string inverter outperforms the central inverter. • Conclusions of use to maintenance firms and operational facilities are obtained. - Abstract: Two complete years of operation of two grid-tied PV facilities is presented. Energetic and economic performance of both installations has been compared. Located in the same place, the installation of these facilities followed the same construction criteria – PV panels, panel support system and wiring – and the facilities are exposed to the same atmospheric temperature and solar radiation. They differ with regard to their inverter topology used: one facility uses a central inverter and the other a string inverter configuration. The performance of the facilities has been determined using a procedure based on a small number of easily obtained parameters and the knowledge of the analyzed system and its operation mode. Electrical losses have been calculated for both systems and a complete comparison between them has been carried out. The results have shown better performance for distributed system in economic and energetic terms

    We demonstrate the capabilities and properties of using Proton Transfer Reaction time-of-flight mass spectrometry (PTR-ToF-MS) to real-time monitor gaseous emissions from industrial scale amine-based carbon capture processes. The benchmark monoethanolamine (MEA) was used as an example of amines needing to be monitored from carbon capture facilities, and to describe how the measurements may be influenced by potentially interfering species in CO2 absorber stack discharges. On the basis of known or expected emission compositions, we investigated the PTR-ToF-MS MEA response as a function of sample flow humidity, ammonia, and CO2 abundances, and show that all can exhibit interferences, thus making accurate amine measurements difficult. This warrants a proper sample pretreatment, and we show an example using a dilution with bottled zero air of 1:20 to 1:10 to monitor stack gas concentrations at the CO2 Technology Center Mongstad (TCM), Norway. Observed emissions included many expected chemical species, dominantly ammonia and acetaldehyde, but also two new species previously not reported but emitted in significant quantities. With respect to concerns regarding amine emissions, we show that accurate amine quantifications in the presence of water vapor, ammonia, and CO2 become feasible after proper sample dilution, thus making PTR-ToF-MS a viable technique to monitor future carbon capture facility emissions, without conventional laborious sample pretreatment.

    Graphical abstract: A flexible paper-based supercapacitor was assembled into a sandwich structure, which exhibits well-retained triangular-shaped curves. The cycle life stability of this device still retains about 96% of the initial capacitance after 2000 cycles at a scan rate of 400 mV/s. An as-fabricated paper-based supercapacitor could light a red LED well after charging at constant potential of 3 V. - Highlights: • A facile approach is proposed to fabricate paper-based supercapacitors. • Apple pectin is an excellent dispersant for MWCNTs. • Paper provides a strong binding and flexible characteristic for electrode. • A paper-based supercapacitor could light a red LED after charging. • This device shows excellent electrochemical performance and cycling stability. - Abstract: We propose a low cost and simple method to prepare a paper-based supercapacitor in this study. Multi-walled carbon nanotubes (MWCNTs) were dispersed with a pectin solution under an ultrasonic homogenizer. Carbon nanotube suspension was prepared using a centrifuge to eliminate impurities. The dispersed MWCNTs suspension was dropped and dried onto the shallow surface of commercial copy paper. A paper-based conductive paper was formed as the electrodes. The electrical conductivity and dispersed morphology of the paper-based conductive paper were examined by four probes, atomic force microscope (AFM), scanning electron microscope (SEM) and transmission electron microscope (TEM). The solid-state electrolyte was prepared by casting a solution of phosphoric acid and polyvinyl alcohol onto a glass plate. The paper-based supercapacitor was constructed with one solid-state electrolyte inserted between two electrodes, which were assembled into a sandwich structure by hot press. The specific capacitance and cycle-life stability of the paper-based supercapacitor was investigated by cyclic voltammetry analysis.

  13. Savannah River Site human error data base development for nonreactor nuclear facilities

    International Nuclear Information System (INIS)

    As part of an overall effort to upgrade and streamline methodologies for safety analyses of nonreactor nuclear facilities at the Savannah River Site (SRS), a human error data base has been developed and is presented in this report. The data base fulfills several needs of risk analysts supporting safety analysis report (SAR) development. First, it provides a single source for probabilities or rates for a wide variety of human errors associated with the SRS nonreactor nuclear facilities. Second, it provides a documented basis for human error probabilities or rates. And finally, it provides actual SRS-specific human error data to support many of the error probabilities or rates. Use of a single, documented reference source for human errors, supported by SRS-specific human error data, will improve the consistency and accuracy of human error modeling by SRS risk analysts. It is envisioned that SRS risk analysts will use this report as both a guide to identifying the types of human errors that may need to be included in risk models such as fault and event trees, and as a source for human error probabilities or rates. For each human error in this report, ffime different mean probabilities or rates are presented to cover a wide range of conditions and influencing factors. The ask analysts must decide which mean value is most appropriate for each particular application. If other types of human errors are needed for the risk models, the analyst must use other sources. Finally, if human enors are dominant in the quantified risk models (based on the values obtained fmm this report), then it may be appropriate to perform detailed human reliability analyses (HRAS) for the dominant events. This document does not provide guidance for such refined HRAS; in such cases experienced human reliability analysts should be involved

    The third phase of a three-phase project investigating the development of coal-based technologies for US Department of Defense (DOD) facilities was completed. The objectives of the project were to: decrease DOD's dependence on foreign oil and increase its use of coal; promote public and private sector deployment of technologies for utilizing coal-based fuels in oil-designed combustion equipment; and provide a continuing environment for research and development of coal-based fuel technologies for small-scale applications at a time when market conditions in the US are not favorable for the introduction of coal-fired equipment in the commercial and industrial capacity ranges. The Phase III activities were focused on evaluating deeply-cleaned coals as fuels for industrial boilers and investigating emissions control strategies for providing ultra-low emissions when firing coal-based fuels. This was addressed by performing coal beneficiation and preparation studies, and bench- to demonstration-scale emissions reduction studies. In addition, economic studies were conducted focused on determining cost and market penetration, selection of incentives, and regional economic impacts of coal-based technologies.

    @@ 1Introduction Chitosan has remarkable potential applications in pharmaceutical and cosmetic formulations[1], e.g. for drug delivery systems, tissue engineering, transplant and cell regeneration due to its excellent biocompatibility, biodegradability, mucoadhesion, etc. Its major drawback as considered for pharmaceutical and cosmetic formulations is its poor solubility due to strong hydrogen bonding and compact structures. Considerable efforts were focused on improving its solubility and enforcing its functionality[1]. As well-known that phosphorylcholine (PC), the structural component of cell membrane, is an amphiphile containing the zwitterionic quaternary ammonium and phosphonic acid moieties (phosphobetaine groups). There has been an intensive effort over the past decades to prepare and explore potential applications of the synthetic PC-polymers[2].In this paper, we describe a facile synthesis of chitosan derivatives containing zwitterionic secondary/tertiary amine and phosphonic acid groups and their further N-phosphobetainates. The polyelectrolyte effect and anti-polyelectrolyte effect of the chitosan-based zwitterionic polyelectrolytes were studied.

  20. Performance based seismic qualification of reinforced concrete nuclear materials processing facilities

    International Nuclear Information System (INIS)

    A seismic qualification of a reinforced concrete nuclear materials processing facility using performance based acceptance criteria is presented. Performance goals are defined in terms of a minimum annual seismic failure frequency. Pushover analyses are used to determine the building's ultimate capacity and relate the capacity to roof drift and joint rotation. Nonlinear dynamic analyses are used to quantify the building's drift using a suite of ground motion intensities representing varying soil conditions and levels of seismic hazard. A correlation between joint rotation and building drift to damage state is developed from experimental data. The damage state and seismic hazard are convolved to determine annual seismic failure frequency. The results of this rigorous approach is compared to those using equivalent force methods and pushover techniques recommended by ATC-19 and FEMA-273

    2003-01-01

    The beam emittance in future linear accelerators for high energy physics and SASE-FEL applications depends highly on the field performance in the accelerating structures, i.e. the damping of higher order modes (HOM). Besides theoretical and laboratory analysis (network analyzer), a beam based analysis technique was established [S. Fartoukh, et.al., Proceedings of the PAC99 Conference] at the TESLA Test Facility (TTF) linac. It uses a charge modulated beam of variable modulation frequency to excite dipole modes. This causes a modulation of the transverse beam displacement, which is observed at a downstream BPM and associated with a direct analysis of the modes at the HOM couplers. Emphasis of this presentation is put on beam instrumentation and signal analysis aspects. A brief introduction of eigenmodes in resonant structures, as well as some interesting measurement results are further presented.

  3. Improving sustainability of maritime transport through utilization of Liquefied Natural Gas (LNG) for propulsion

    International Nuclear Information System (INIS)

    Today, most merchant vessels use Heavy Fuel Oils (HFOs) for ship propulsion. These fuels are cost effective but they produce significant amounts of noxious emissions. In order to comply with International Maritime Organization (IMO) rules, Liquefied Natural Gas (LNG) is becoming an interesting option for merchant ships. The aim of the research presented in this paper is to analyse the economic upturn that can result from the use of LNG as fuel for merchant ships and to assess the effects of its utilization in terms of environmental impact. In the first part of the study, a statistical analysis of maritime traffic is carried out in order to identify which merchant ship types could most benefit from using LNG as fuel for ship propulsion. Traffic data of world ships related to the months of May 2008, 2009 and 2010 are analysed. Roll-on/Roll-off vessels (RoRo) and tanker ships spend most of their sailing time in Emission Control Areas (ECA) consequently appear to be the best candidates for LNG use. In particular, the use of LNG is most profitable for tanker ships in the range of 10,000–60,000 DWT (deadweight). In the second part of the study, operational costs and pollutant emission reduction, following LNG implementation, are calculated for a 33,000 DWT tanker ship. Results show that LNG leads to a reduction of 35% of operational costs and 25% of CO2 emissions. The possibility of improving energy efficiency on board is analysed considering that combustion gases, produced by LNG, are cleaner, thus simplifying the introduction of exhaust gas heat recovery. Two options are considered: simple heat recovery and heat recovery to drive a turbine (ORC). The results show that it is possible to achieve a reduction in fuel consumption of up to 15%. - Highlights: • Ship propulsion accounts for a large amount of noxious emissions in costal/harbour areas. • Today price differential between fuel oil and natural gas is increasing. • The use of Liquefied Natural Gas as fuel

    Porous nanostructures exhibit excellent catalytic properties due to high surface-to-volume ratio, good surface reactivity and various structural features, but controlling the distribution, size, shape and density of pores and structural features of these particles is highly challenging. Herein, we report a tunable dealloying-based facile synthetic strategy to form highly porous Au core/porous shell nanoparticles (CPS NPs) in high yield by selectively dissolving Ag atoms from Au/Au-Ag core/alloy shell NPs. The CPS NPs exhibit a very short induction time, high conversion rate constant, low activation energy and high turnover frequency due to their catalytically active porous shells containing networked thin ligaments, surface defects, ultra-high porosity and photothermal properties. The CPS NPs are more catalytic Au NPs than other reported Au nanostructures, and the strategy and results open avenues in porous nanostructures and nanocatalysts.Porous nanostructures exhibit excellent catalytic properties due to high surface-to-volume ratio, good surface reactivity and various structural features, but controlling the distribution, size, shape and density of pores and structural features of these particles is highly challenging.

    A simplified encapsulation strategy for metal-oxide based TFTs, using ozone instead of water as an oxygen source in a low-temperature ALD process is demonstrated. Thereby, the threshold voltage remains unaltered and the hysteresis is permanently reduced. Costly energy- and time-consuming post-treatment processes can be avoided. This concept is widely applicable to various encapsulation materials (e.g., Al2 O3 , TiO2 , ZrO2 ) and metal-oxide channel semiconductors (e.g., zinc-tin-oxide (ZTO), indium-gallium-zinc-oxide (IGZO)).

    In order to construct an infrastructure to produce nuclear data, we studied three main items; (1) Study on the possibility to construct a facility for nuclear data production, (2) Production of nuclear data for nuclear power plant, and (3) Pulsed neutron source based on a 100-MeV electron linac at Pohang Accelerator Laboratory (PAL). We confirmed the possibility to build a nuclear data production facility utilizing a 100-MeV electron linac at PAL and manpower who wanted to participate the nuclear data production experiments. In order to measure the nuclear data for nuclear power plant, we used several nuclear data production facilities in abroad. We measured total cross sections and neutron caprure cross sections for {sup nat}Dy and {sup nat}Hf using the pulsed neutron facility in the Research Reactor Institute, Kyoto University (KURRI). The neutron capture cross sections for {sup 161,162,163,164}Dy were measured at KURRI in the neutron energy region between 0.001 eV and several tens keV, and at the fast neutron facility in Tokyo Institute of Technology in the neutron energy region between 10 keV and 100 keV. We also measured the neutron capture cross sections and gamma multiplicity of {sup 232}Th at the IBR30 in Dubna, Russia. We have construct a pulsed neutron source using a 100-MeV electron linac at PAL. We measured neutron time-of-flight (TOF) spectra in order to check the characteristics of the pulsed neutron source. We also measured a neutron total cross sections of W and Cu. The pulsed neutron facility can be utilized in the education facility for nuclear data production and the test facility for the R and D purpose of the nuclear data production facility. 29 refs., 57 figs., 22 tabs.

    International Nuclear Information System (INIS)

    Jointly sponsored by SIGTTO and GIIGNL, LNG Shipping at 50 is a celebration of the first half century of commercial LNG carrier and terminal operations. The publication also marks the 35. and 43. anniversaries of the Society of International Gas Tanker and Terminal Operators (SIGTTO) and the International Group of LNG Importers (GIIGNL), respectively. The two organisations and their memberships have done a sterling job of developing guidance on safe operations; promulgating industry best practice; and providing forums for the airing of concerns and discussion of topical issues. The exemplary safety record built up by the LNG shipping and terminal industry over the past five decades owes much to the central roles played by SIGTTO and GIIGNL. The LNG industry has an exceptional story to tell and LNG Shipping at 50 contributes to the telling of that story. The publication starts with a review of the early days to show how the industry developed the innovative solutions needed to ensure the safe transport of LNG by sea. The articles in this section then describe how these solutions were then continuously improved upon as more countries turned to seaborne natural gas imports to meet their energy needs. Pioneering people, ships, shipyards, containment systems, class societies and equipment suppliers are reviewed to highlight the key role they played in facilitating the safe and smooth operation of the LNG supply chain, including at the critical ship/shore interface. Safety is the No 1 priority in the LNG industry and the safety regime section of the magazine examines the cornerstones that underpin an unparalleled safety record. Quite aside from the IGC Code and the work of SIGTTO and GIIGNL, there are the contributions of class, training establishments, vetting programmes and escort tug services. LNG Shipping at 50's survey of progress to date is followed by a look at the many innovations introduced by the industry in more recent years, not least floating LNG

These proposals have been adopted and are the object of three legislative texts: the decree no. 2005-607 from May 27 2005 relative to the tariffing rules, the by-law from May 27, 2005 relative to the definition of balancing areas, and the advice from May 27, 2005 relative to the tariffs of use of natural gas transportation networks. In application of article 7 of the law from January 3, 2003, the implementation of the first tariffs of use of natural gas transportation networks and of liquefied natural gas (LNG) facilities is defined in the decree no. 2004-994 from September 21, 2004. On the main transportation network, the tariffing is of 'input-output' type and does not depend on the distance, while at the regional network scale, the tariffing is linked with the distance. The tariff of use of LNG facilities is the sum of 4 terms: a fixed term applied to each batch unloaded at the methane terminal, a term proportional to the unloaded LNG quantities, a term depending on the duration of use of LNG storage facilities and a term covering the gas consumptions of LNG facilities. This document gathers these different legislative texts with their appendixes. (J.S.)

  11. Proceedings of the first international seminar on seismic base isolation for nuclear power facilities

    International Nuclear Information System (INIS)

    The First International Seminar on Seismic Base Isolation of Nuclear Power Facilities was organized by the authors of this paper. It was held in San Francisco, California, USA, on August 21--22, 1989, in conjunction with the tenth International Conference on Structural Mechanics in Reactor Technology (SMiRT-10). The purpose of the seminar was to provide an international forum for discussion on the application of base isolation to nuclear power plants and of its effectiveness in reducing seismic loads and permitting standard plant designs. It also provided an opportunity for technical interchange between base isolation system designers, structural engineers, and nuclear power plant engineers. Seismic isolation is certainly one of the most significant earthquake engineering developments in recent years. This was clearly demonstrated by the very large attendance at this seminar and the various papers presented. Isolation system act as filters that reduce the seismic forces and increase the ability of isolated structures and their contents to withstand the damaging effects of earthquake motions. Each individual paper has been cataloged separately

    The RACF provides computing support to a broad spectrum of scientific programs at Brookhaven. The continuing growth of the facility, the diverse needs of the scientific programs and the increasingly prominent role of distributed computing requires the RACF to change from a system to a service-based SLA with our user communities. A service-based SLA allows the RACF to coordinate more efficiently the operation, maintenance and development of the facility by mapping out a matrix of system and service dependencies and by creating a new, configurable alarm management layer that automates service alerts and notification of operations staff. This paper describes the adjustments made by the RACF to transition to a service-based SLA, including the integration of its monitoring software, alarm notification mechanism and service ticket system at the facility to make the new SLA a reality.

    Full Text Available Objective: To assess the effects of facility-based interventions using existing resources to improve overall patient attendance and adherence to antiretroviral therapy (ART at ART-providing facilities in Uganda. Methods: This was an interventional study which tracked attendance and treatment adherence of two distinct cohorts: experienced patients who had been on treatment for at least 12 months prior to the intervention and patients newly initiated on ART before or during the intervention. The interventions included instituting appointment system, fast-tracking, and giving longer prescriptions to experienced stable patients. Mixed-effects models were used to examine intervention effects on the experienced patients, while Cox proportional hazards models were used to determine the intervention effects on time until newly treated patients experienced gaps in medication availability. Results: In all, 1481 patients’ files were selected for follow-up from six facilities – 720 into the experienced cohort, and 761 into the newly treated cohort. Among patients in the experienced cohort, the interventions were associated with a significant reduction from 24.4 to 20.3% of missed appointments (adjusted odds ratio (AOR: 0.67; 95% confidence interval (CI: 0.59–0.77; a significant decrease from 20.2 to 18.4% in the medication gaps of three or more days (AOR: 0.69; 95% CI: 0.60–0.79; and a significant increase from 4.3 to 9.3% in the proportion of patients receiving more than 30 days of dispensed medication (AOR: 2.35; 95% CI: 1.91–2.89. Among newly treated patients, the interventions were associated with significant reductions of 44% (adjusted hazard rate (AHR: 0.56, 95% CI: 0.42–0.74 and 38% (AHR: 0.62; 95% CI: 0.45–0.85 in the hazards of experiencing a medication gap of 7 and 14 days or more, respectively. Conclusions: Patients’ adherence was improved with low-cost and easily implemented interventions using existing health facilities

  16. A Comparison of Space and Ground Based Facility Environmental Effects for FEP Teflon. Revised

    1998-01-01

    Fluorinated Ethylene Propylene (FEP) Teflon is widely used as a thermal control material for spacecraft, however, it is susceptible to erosion, cracking, and subsequent mechanical failure in low Earth orbit. One of the difficulties in determining whether FEP Teflon will survive during a mission is the wide disparity of erosion rates observed for this material in space and in ground based facilities. Each environment contains different levels of atomic oxygen, ions, and vacuum ultraviolet (VUV) radiation in addition to parameters such as the energy of the arriving species and temperature. These variations make it difficult to determine what is causing the observed differences in erosion rates. This paper attempts to narrow down which factors affect the erosion rate of FEP Teflon through attempting to change only one environmental constituent at a time. This was attempted through the use of a single simulation facility (plasma asher) environment with a variety of Faraday cages and VUV transparent windows. Isolating one factor inside of a radio frequency (RF) plasma proved to be very difficult. Two observations could be made. First, it appears that the erosion yield of FEP Teflon with respect to that of polyimide Kapton is not greatly affected by the presence or lack of VUV radiation present in the RF plasma and the relative erosion yield for the FEP Teflon may decrease with increasing fluence. Second, shielding from charged particles appears to lower the relative erosion yield of the FEP to approximately that observed in space, however it is difficult to determine for sure whether ions, electrons, or some other components are causing the enhanced erosion.

  17. Feasibility study for a recirculating linac-based facility for femtosecond dynamics

    International Nuclear Information System (INIS)

    LBNL is pursuing design studies and the scientific program for a facility dedicated to the production of x-ray pulses with ultra-short time duration, for application in dynamical studies of processes in physics, biology, and chemistry. The proposed x-ray facility has the short x-ray pulse length (∼60 fs FWHM) necessary to study very fast dynamics, high flux (up to approximately 10E11 photons/sec/0.1 percentBW) to study weakly scattering systems, and tuneability over 1-12 keV photon energy. The hard x-ray photon production section of the machine accommodates seven 2-m long undulators. Design studies for longer wavelength sources, using high-gain harmonic generation, are in progress. The x-ray pulse repetition rate of 10 kHz is matched to studies of dynamical processes (initiated by ultra-short laser pulses) that typically have a long recovery time or are not generally cyclic or reversible and need time to allow relaxation, replacement, or flow of the sample. The technique for producing ultra-short x-ray pulses uses relatively long electron bunches to minimize high-peak-current collective effects, and the ultimate x-ray duration is achieved by a combination of bunch manipulation and optical compression. Synchronization of x-ray pulses to sample excitation signals is expected to be of order 50 - 100 fs. Techniques for making use of the recirculating geometry to provide beam-based signals from early passes through the machine are being studied

    This study examined the effect of a job aids-focused intervention on quality of facility-based postnatal counseling, and whether increased communication improved in-hospital newborn care and maternal knowledge of home practices and danger signs requiring urgent care. Ensuring mothers and newborns receive essential postnatal services, including health counseling, is integral to their survival. Yet, quality of clinic-based postnatal services is often low, and evidence on effective improvement strategies is scarce. Using a pre-post randomized design, data were drawn from direct observations and interviews with 411 mother-newborn pairs. Multi-level regression models with difference-in-differences analyses estimated the intervention's relative effect, adjusting for changes in the comparison arm. The mean percent of recommended messages provided to recently-delivered women significantly improved in the intervention arm as compared to the control (difference-in-differences [∆i - ∆c] +30.9, 95 % confidence interval (CI) 19.3, 42.5), and the proportion of newborns thermally protected within the first hour (∆i - ∆c +33.7, 95 % CI 19.0, 48.4) and delayed for bathing (∆i - ∆c +23.9, 95 % CI 9.4, 38.4) significantly increased. No significant changes were observed in early breastfeeding (∆i - ∆c +6.8, 95 % CI -2.8, 16.4) which was nearly universal. Omitting traditional umbilical cord substances rose slightly, but was insignificant (∆i - ∆c +8.5, 95 % CI -2.8, 19.9). The proportion of mothers with correct knowledge of maternal (∆i - ∆c +27.8, 95 % CI 11.0, 44.6) and newborn (∆i - ∆c +40.3, 95 % CI 22.2, 58.4) danger signs grew substantially, as did awareness of several home-care practices (∆i - ∆c +26.0, 95 % CI 7.7, 44.3). Counseling job aids can improve the quality of postnatal services. However, achieving reduction goals in maternal and neonatal mortality will likely require more comprehensive approaches to link enhanced facility services with

    Highlights: • Measurement of plasma heat flux in the mirror of a GDT device had been conducted. • The power density up to 0.25 GW m{sup −2} was experimentally obtained. • Steady state operation has not been achieved due to short NBI pulse. • The possibility of creating the PMI setup based on GDT had been discussed. -- Abstract: The power density along the field lines in the scrape-off layer plasma in machines of the class of ITER, Wendelstein 7-X, NSTX-U is in the range of few hundreds megawatt per square meter. It is crucial for the future of tokamaks and stellarators to develop the plasma science and component technology to handle such high plasma heat fluxes. It would be valuable to produce parallel plasma heat fluxes at these power densities, impinging on test components at very shallow angles, as planned in tokamaks. The primary objective of this work is the direct measurement of plasma heat fluxes in the mirror throat of a Gas Dynamic Trap device. Options to develop a facility for plasma–material interaction testing based on the Gas Dynamic Trap are discussed.

    From October 18 to 20, 2006, a symposium, Developing and Understanding a Hospital-based Proton Facility: Bringing Physics Into Medicine, was held at the Renaissance Esmeralda Resort and Spa, Indian Wells, California. The event was offered by the Department of Radiation Medicine at Loma Linda University (LLU), supported by the Telemedicine and Advanced Technology Research Center (TATRC) and the United States Army Medical Research and Materiel Command (USAMRMC). The meeting was intended to discuss factors involved in planning, developing, and operating a hospital-based proton treatment center. It brought together some of the most distinguished physicists, radiation biologists, and radiation oncologists in the world, and more than 100 individuals participated in the three-day educational offering. This overview reports on the event and introduces several papers written by many of the speakers from their presentations, for publication in this issue of Technology in Cancer Research and Treatment. Both the symposium and the papers are appropriate for this journal: exploitation of technology was one of the underlying themes of the symposium.

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

    Full Text Available BACKGROUND: Health facilities in many low- and middle-income countries face several types of barriers in delivering quality health services. Availability of resources at the facility may significantly affect the volume and quality of services provided. This study investigates the effect of supply-side determinants of maternity-care provision in India. METHODS: Health facility data from the District-Level Household Survey collected in 2007-2008 were analyzed to explore the effects of supply-side factors on the volume of delivery care provided at Indian health facilities. A negative binomial regression model was applied to the data due to the count and over-dispersion property of the outcome variable (number of deliveries performed at the facility. RESULTS: Availability of a labor room (Incidence Rate Ratio [IRR]: 1.81; 95% Confidence Interval [CI]: 1.68-1.95 and facility opening hours (IRR: 1.43; CI: 1.35-1.51 were the most significant predictors of the volume of delivery care at the health facilities. Medical and paramedical staff were found to be positively associated with institutional deliveries. The volume of deliveries was also higher if adequate beds, essential obstetric drugs, medical equipment, electricity, and communication infrastructures were available at the facility. Findings were robust to the inclusion of facility's catchment area population and district-level education, health insurance coverage, religion, wealth, and fertility. Separate analyses were performed for facilities with and without a labor room and results were qualitatively similar across these two types of facilities. CONCLUSIONS: Our study highlights the importance of supply-side barriers to maternity-care India. To meet Millennium Development Goals 4 and 5, policymakers should make additional investments in improving the availability of medical drugs and equipment at primary health centers (PHCs in India.
