    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.

    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.

    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.

  7. 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.

    . It is also likely that in the coming years there will be almost ten filling stations for liquid methane in operation in southern Sweden. The market analysis shows that several industries in the iron and steel industry are already interested in converting to LNG, mainly to cope with environmental demands. Also in the chemical industry there is an interest in using LNG, while many of the companies in the pulp and paper industry do not see LNG as a particularly attractive option. The latter have access to their own fuel and several companies have also adopted policies aiming at becoming fossil fuel free in the near future. The total conversion potential to replace oil with LNG industry amounted to 6.8 TWh/year, divided among 100 users. The greatest potential is in central Sweden (Dalarna, Gaevleborg, Vaermland) and along the Norrland coast. 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. Transport distance is too long to be economically feasible to supply industries in central and northern Sweden. To provide these regions with LNG the intermodal freight terminals in Gaevle, Sundsvall and Luleaa would be able to function as strategic hubs. These three terminals covering the areas and industries that according to the market analysis is most interesting for LNG supplies, and are all well connected both by road, rail and seaway, allowing for transfer between different modes. All harbours also have the potential to qualify for receiving LNG deliveries by ship. There is also an interest in using liquid methane for heavy transport and coaches/intercity buses, because the distribution of liquid methane is cost effective, and the vehicles get longer range due to the high energy density of liquid methane. Yet, however, the availability of vehicles is limited and the infrastructure is not developed, but both the availability of vehicles and

    2011-01-01

    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 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.

  19. Analysis and efficiency enhancement of a boil-off gas reliquefaction system with cascade cycle on board LNG carriers

    International Nuclear Information System (INIS)

    Highlights: • An LNG boil-off gas reliquefaction plant on board LNG carriers is improved. • Relevant improvements deals with a study on BOG–C2H4–C3H6 cascade system. • A novel design is proposed to reduce power consumption and COP improvement. • Efficiency improvement by BOG cold energy recovery and compression heat rejection. • Efficiency increase operating in parallel with the engine fuel gas supply system. - Abstract: In this paper, an LNG boil-off gas (BOG) reliquefaction plant operating in accordance with cascade vapor compression cycles, using propylene and ethylene as refrigerants, on board LNG carriers is investigated. As consequence of the analysis results, a new and original design is proposed to reduce power consumption and improve its exergy efficiency. Through energy and exergy analysis, a thermodynamic model is carried out to analyse and evaluate operating conditions as well as to obtain performance values such as the Coefficient of Performance (COP), exergy efficiency, irreversibilities and specific energy consumption. The thermodynamic analysis is performed using the Engineering Equation Solver (EES) software environment. The results of the improved design implemented on the reliquefaction plant for LNG tank conditions of -160.82 °C, a plant BOG input temperature of −125 °C and 25 °C seawater, give COP values of 0.22 and an exergetic efficiency of 37%, such values being 22.22% and 19.35% greater than the original design. The specific energy consumption decreases 14.66% to 0.64 kW h per kg/s of natural BOG. The proposal for improving efficiency is founded on BOG cold energy recovery and BOG compression heat rejection with cooling water in the intercoolers

  20. 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

    Evaporation rates of cryogenic fluids in the storage tank are largely influenced by three factors: the thermodynamic properties of the fluid, the storage pressure and the rate of heat exchanged between the ambient air and the fluid through the tank walls. The study of the influence of each of these factors has required the development of two calculation programs. The first one estimates the LNG thermodynamic properties by using the Benedict Webb and Rubbin (BWR) equation of state [1], whereas in the second program, the rate of heat transfer in LNG tanks is calculated. In this communication, the procedure followed in the second program for modelling the heat transfer process will be presented. The analysis of the influence when modifying key parameters such as the LNG liquid level and the ambient air temperature on the rate of heat transfer to the tank and the temperature profile in the vapor side will be carried out. This analysis was done on LNG storage tanks located at Skikda (Algeria). This study will permit the LNG plant operators to be aware of the importance in keeping track of the measured parameters and this for a good monitoring of LNG storage tanks. (author)

    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。

    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

    采用数值模拟方法对飞机撞击特大型 LNG 储罐的全过程进行仿真分析。分析中采用 LS-DYNA 有限元程序,考虑罐体、储液与保温层间的相互问题,建立了 F -15战斗机的 SPH 模型,对飞机材料的选择和参数确定进行了详细分析,并以 Riera 法为依据,对 F -15战斗机 SPH 模型撞击刚体所产生的荷载进行了对比验证,对比结果证明了 SPH 模型的可靠性和实用性。分析结果表明:撞击角度越大,外罐所承受的撞击能量越大,相应的内罐破坏越小,因此垂直撞击为最不利撞击角度;撞击高度对整体工况计算结果影响不大,储罐在经受215 m/s 撞击速度撞击下均出现了严重破坏;112 m/s 撞击速度时内罐尚有安全余量,160 m/s 撞击速度时内罐撞击中心区域内材料已达到极限应变,因此可认为目前设计方法设计的储罐所能承受的最大撞击速度为160 m/s。%Whole process of aircraft's crashing into an extra-large liquefied natural gas (LNG)storage tank was simulated using a numerical method.The LS-DYNA program was used to build the SPH model of a F-15 fighter considering the interaction of tank,LNG,and insulating layer.The plane's material model and parameters were chosen and analyzed.Based on Riera method,the comparison between the crash load obtained with the numerical method and that with the theoretical method was made to prove the reliability and practicability of the SPH model of a F-15 fighter. The analysis results revealed that the impact energy absorbed by the outer tank increases with increase in impact angle,so the vertical impact is the worst impact angle;the height of the aircraft impact position affects the response of the tank little;when the aircraft impact speed is 215m /s,the tank is destroyed seriously;if the speed reduces to 160m /s,the stress of the inner tank material approaches the maximum value,so 160m /s can be taken as the maximum

    comes to the purchase costs and the railroad and large-scale sea transport costs. It is also worth noticing that the cost estimation models used in this study sometimes contain large steps for the different cost situations. This is the case for small-scale/base-load ships, purchase cost for Norwegian/Algerian LNG and wagon transport/system trains. The results are hence sometimes less accurate. As a side assignment, the costs for peak-shaving by the use of LNG is looked into. 20-30 MW for 24 hours per year need to be cut at Oeresundskraft's combined power and heat plant in Helsingborg. Here, the possibility of utilising portable LNG containers (as used by the Norwegian company Liquiline) is studied. 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. The Natural Gas market price largely follows the oil price and as a consequence from this, LNG prices are also linked to the source of energy which it is primarily supposed to replace. The question is whether the market price is reduced - or at least less increased - due to

  9. 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

    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.

    comes to the purchase costs and the railroad and large-scale sea transport costs. It is also worth noticing that the cost estimation models used in this study sometimes contain large steps for the different cost situations. This is the case for small-scale/base-load ships, purchase cost for Norwegian/Algerian LNG and wagon transport/system trains. The results are hence sometimes less accurate. As a side assignment, the costs for peak-shaving by the use of LNG is looked into. 20-30 MW for 24 hours per year need to be cut at Oeresundskraft's combined power and heat plant in Helsingborg. Here, the possibility of utilising portable LNG containers (as used by the Norwegian company Liquiline) is studied. 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).

    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

  14. 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)

    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. 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

  17. World economic growth pushing LNG use

    International Nuclear Information System (INIS)

    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

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

    This paper discussed the protection design for an intake seawater pipeline that will be built for a liquefied natural gas (LNG) project. The limit equilibrium approach was used to estimate the geometry of the protection layer with respect to the holding capacity of the drag anchors in cohesionless soil, incorporating a more realistic 3-dimensional failure pattern in the soil as well as the force acting on the back of the fluke. The study addressed all technical and executive points related to the pipeline construction, including anchor type, ship load, geotechnical properties of the protected zone and the underlying seabed, and the procedure to calculate the geometry of the protection layer. The protection layer must account for the complexity of interactions among anchor, anchor chain, sea bed, and rock armour. This analytical method provided logical results more quickly and at a lower cost than model testing. 14 refs., 3 tabs., 9 figs.

    @@ 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.

    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

    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)

    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.

  13. 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

    2015-12-01

    Boil-off gas (BOG) generation and its handling are important issues in Liquefied natural gas (LNG) value chain because of economic, environment and safety reasons. Several variants of reliquefaction systems of BOG have been proposed by researchers. Thermodynamic analyses help to configure them and size their components for improving performance. In this paper, exergy analysis of reliquefaction system based on nitrogen-driven reverse Brayton cycle is carried out through simulation using Aspen Hysys 8.6®, a process simulator and the effects of heat exchanger size with and without related pressure drop and BOG compressor exit pressure are evaluated. Nondimensionalization of parameters with respect to the BOG load allows one to scale up or down the design. The process heat exchanger (PHX) requires much higher surface area than that of BOG condenser and it helps to reduce the quantity of methane vented out to atmosphere. As pressure drop destroys exergy, optimum UA of PHX decreases for highest system performance if pressure drop is taken into account. Again, for fixed sizes of heat exchangers, as there is a range of discharge pressures of BOG compressor at which the loss of methane in vent minimizes, the designer should consider choosing the pressure at lower value.

    The results of an investigation of human factors engineering and human reliability applications to LNG release prevention and control are reported. 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.

  17. The Malaysia LNG experience

    International Nuclear Information System (INIS)

    This paper summarizes the nature of the LNG trade, the essential components and characteristics of an LNG project, and relates the Malaysia LNG experience to project realization with some emphasis on the financial aspects of the project. Twelve offshore lending institutions were involved in the total project loop providing U.S. dollar equivalents of 4.0 billions with interest rates ranging from 5% to 8%. The total project was completed on schedule and within budget except for the ships which got caught in the political development of the Malaysian petroleum industry at that time

    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.

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

    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

    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

  3. 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%.

  4. Chile exploits LNG

    Energy Technology Data Exchange (ETDEWEB)

    1980-03-01

    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.

    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)

  7. 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.

  9. 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

    The operation of liquefied natural gas (LNG) is pioneering within the PETROBRAS System. PETROBRAS Transporte - TRANSPETRO is going to operate two flexible LNG terminals, located in Ceara and Rio de Janeiro. In accordance with the Corporate Health, Safety and Environmental (HSE) Directive - Training, Education and Awareness, PETROBRAS Transporte S.A. - TRANSPETRO has prepared an action plan with the objective of ensuring the operational safety of the undertaking. Among other actions a training program for the emergency control of LNG will be inserted into the timetable. 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)

  12. 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

  13. 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

  15. 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).

  16. The LNG Industry - 2014

    International Nuclear Information System (INIS)

    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

    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.

    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.

    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.

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

    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

    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.

    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

    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.)

  9. 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

    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

  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

  16. Evolving framework of the LNG industry: Expected growth and continuing importance of safety

    International Nuclear Information System (INIS)

    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. This paper discusses measures for the future based on the author's many years of experience, particularly in the field of receiving terminals

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

    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.

  18. 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.

    suppliers portfolio. Increased possibilities of choice for importers, the widening of the group of exporting countries, and the increased integration of the European market, thanks to the possibility of redirecting cargoes depending on single countries' supply-demand balance, would contribute decisively to security of supply, market globalization and competition (between importers) in the industry (IEA, 2004). Yet, it must be stressed that import via tanker appears to be competitive with import via pipe only for the medium-long distances. As far as LNG chain is concerned, the element that so far has attracted the least attention, though being not less important than the other two, is certainly shipping. Being the link between the producing/exporting country and the importing country, and having been subject to major changes in the last few years, it is particularly interesting to analyze it singularly, aiming to understand how it is linked to the other elements of LNG value chain, besides studying industry dynamics. This paper will address this issue, aiming also to understand what has been and what will be in the future the evolutionary trajectory of this segment, starting from an analysis of operative and planned gas tankers, their size, their routes and their contractual situation. This analysis can be useful to make hypothesis about the growth of the spot market and, consequently, of market liquidity.

    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.

    This article presents an iterative six-step risk analysis methodology based on hybrid Bayesian networks (BNs). In typical risk analysis, systems are usually modeled as discrete and Boolean variables with constant failure rates via fault trees. Nevertheless, in many cases, it is not possible to perform an efficient analysis using only discrete and Boolean variables. The approach put forward by the proposed methodology makes use of BNs and incorporates recent developments that facilitate the use of continuous variables whose values may have any probability distributions. Thus, this approach makes the methodology particularly useful in cases where the available data for quantification of hazardous events probabilities are scarce or nonexistent, there is dependence among events, or when nonbinary events are involved. The methodology is applied to the risk analysis of a regasification system of liquefied natural gas (LNG) on board an FSRU (floating, storage, and regasification unit). LNG is becoming an important energy source option and the world's capacity to produce LNG is surging. Large reserves of natural gas exist worldwide, particularly in areas where the resources exceed the demand. Thus, this natural gas is liquefied for shipping and the storage and regasification process usually occurs at onshore plants. However, a new option for LNG storage and regasification has been proposed: the FSRU. As very few FSRUs have been put into operation, relevant failure data on FSRU systems are scarce. The results show the usefulness of the proposed methodology for cases where the risk analysis must be performed under considerable uncertainty.

    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.

All the methods were evaluated for their potential applicability for use in the LNG railroad application. After reviewing the documents included in this report, as well as others not included because of repetition, the Department of Energy (DOE) Hydrogen Safety Plan Checklist is most suitable to be adapted to the LNG railroad application. This report was developed to survey industries related to rail transportation for methodologies and tools that can be used by the FRA to review and evaluate safety assessments submitted by the railroad industry as a part of their implementation plans for liquefied or compressed natural gas storage ( on-board or tender) and engine fueling delivery systems. The main sections of this report provide an overview of various methods found during this survey. In most cases, the reference document is quoted directly. The final section provides discussion and a recommendation for the most appropriate methodology that will allow efficient and consistent evaluations to be made.

    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.

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. The third and last group contains the projects with the least chance of success as things currently stand

    液化天然气(LNG)具有低温、易挥发、易燃、易爆的特性,其场站安全问题凸显.研究结合某LNG汽车加注站加注枪或管道LNG溢出的可能性事故,对事故发生概率及后果进行定量分析,其中事故后果的确定采用DEGADIS和LNGFire3模型.文章结合相关文献提供的伤害准则数据,得出人员受伤等级和死亡率,进而确定事故造成的个人风险值.与英国、荷兰等国家和机构制定的个人风险标准进行比较,所得的个人风险大大低于标准极限值,同时表明将5kW/m2作为安全距离临界热辐射强度的合理性.%Liquefied natural gas (LNG) has special hazard properties, such as cryogenic, volatile, flammable and explosive, so that the safety concern of a LNG station becomes one of the most important issues. The probable accident scenario of a LNG spill due to breakage of a filling gun or pipe during the filling process was considered and the probability and consequence of the hazard had been analyzed quantitatively. The consequences of the accident were predicted with DEGADIS and LNGFire3 models, respectively. The injury and casualty of the accident were determined with those criteria given by published literatures, and the value of the individual risk was obtained accordingly. In comparison with the standards of various countries and organizations such as Britain and Netherlands,it is found that the calculated value of the individual risk is much lower than the safety limit, and it is shown that using the radiation flux of 5 kW/m2 as the threshold in determination of the exclusive distance is reasonable.

  9. Numerical simulations of LNG vapor dispersion in Brayton Fire Training Field tests with ANSYS CFX

    International Nuclear Information System (INIS)

    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.

  10. 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.

Due to heat entering the cryogenic tank during storage and transportatio...

  13. 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

  15. LNG as vehicle fuel and the problem of supply: The Italian case study

    International Nuclear Information System (INIS)

    The transport sector represents a major item on the global balance of greenhouse gas (GHG) emissions. Natural gas is considered the alternative fuel that, in the short-medium term, can best substitute conventional fuels in order to reduce their environmental impact, because it is readily available at a competitive price, using technologies already in widespread use. It can be used as compressed gas (CNG) or in the liquid phase (LNG), being the former more suitable for light vehicles, while the latter for heavy duty vehicles. The purpose of this paper is to outline the potential of LNG as vehicle fuel, showing positive and negative aspects related to its introduction and comparing the different supply options with reference to the Italian scenario, paying particular attention to the possibility of on site liquefaction. The analysis has highlighted that purchasing LNG at the regasification terminal is convenient up to a terminal distance of 2000 km from the refuelling station. The liquefaction on site, instead, asks for liquefaction efficiency higher than 70% and low natural gas price and, as liquefaction technology, the let-down plants at the pressure reduction points along the pipeline are the best option to compete with direct supply at the terminal. -- Highlights: •LNG potential as vehicles fuel is analysed. •A SWOT analysis for LNG introduction in the Italian market is presented. •An economic comparison of different supply options is performed. •Possible micro-scale liquefaction technologies are evaluated

  18. 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.

    To guarantee the safety of membrane LNG tank (No96 type), local strength analysis of hull structure under sloshing shock is essential as well as insulation box. With considering the difference of the analysis targets, and in order to simplify modeling and calculation work, several FE modeling methods, such as extension of insulation box, simulation of mastic and basic size of finite element mesh, have been put forward for local strength analysis of hull structure. Moreover, validity of the proposed methods has been verified. The result shows that the number of freedom of the structural FE model will be reduced a lot and the calculation precision can be guaranteed when proposal is adopted. The research can provide local strength analysis of membrane LNG tank (No96 type) hull structure under sloshing load and related guidance with effective reference.%为保证薄膜型LNG船(No96型)的营运安全,除绝缘箱外,还有必要对晃荡冲击载荷作用下船体结构进行局部强度分析.考虑到分析对象的不同,同时为了简化有限元模型和降低船体结构局部分析的计算工作量,针对船体结构局部强度分析中绝缘箱建模范围,树脂绳模拟方式以及绝缘箱网格基本尺寸提出了建议并进行了可行性验证.研究表明,建议方法可以在满足计算精度的前提下,极大减少船体结构局部强度分析的工作量,可为晃荡冲击载荷作用下薄膜型LNG船(No96型)船体结构局部强度分析及相关规范制定提供有效的参考.

    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.

    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

    The objective of this study was to investigate development of a low-cost liquid natural gas (LNG) vehicle fuel storage tank with low fuel boil-off, low tank pressure, and high safety margin. One of the largest contributors to the cost of converting a vehicle to LNG is the cost of the LNG fuel tank. To minimize heat leak from the surroundings into the low-temperature fuel, these tanks are designed as cryogenic dewars with double walls separated by an evacuated insulation space containing multi-layer insulation. The cost of these fuel tanks is driven by this double-walled construction, both in terms of materials and labor. The primary focus of the analysis was to try to devise a fuel tank concept that would allow for the elimination of the double-wall requirement. Results of this study have validated the benefit of vacuum/MLI insulation for LNG fuel tanks and the difficulty in identifying viable alternatives. The thickness of a non-vacuum insulation layer would have to be unreasonably large to achieve an acceptable non-venting hold time. Reasonable hold times could be achieved by using an auxiliary tank to accept boil-off vapor from a non-vacuum insulated primary tank, if the vapor in the auxiliary tank can be stored at high pressure. The primary focus of the analysis was to try to devise a fuel tank concept that allowed for the elimination of the double-wall requirement. Thermodynamic relations were developed for analyzing the fuel tank transient response to heat transfer, venting of vapor, and out-flow of either vapor or liquid. One of the major costs associated with conversion of a vehicle to LNG fuel is the cost of the LNG fuel tank. The cost of these tanks is driven by the cryogenic nature of the fuel and by the fundamental design requirements of long non-venting hold times and low storage pressure.

    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. Some results concerning Algerian LNG chairs Hassi R'mel-Skikda are furnished. (authors)

    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.

    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.

  13. Asia-Pacific focus of coming LNG trade boom

    International Nuclear Information System (INIS)

    This paper reports that the Asia-Pacific region remains the centerpiece of a booming world trade in liquefied natural gas. Biggest growth in LNG demand is expected from some of the region's strongest economies such as Japan, South Korea, and Taiwan, Key LNG exporters such as Brunei, Malaysia, and Indonesia are scrambling to implement projects to meet that expected demand growth. Uncertainties cloud the outlook for Far East LNG trade, Australia, for one, is more cautious in pressing expansion of its LNG export capacity as more competing LNG expansions spring up around the world, notably in the Middle East and Africa

    2010-09-15

    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.

  16. 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.

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

  1. 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

    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)

Combining theories with cases of study, we analyzed the influ-ences of opportunism and limited rationality on the trade patterns in terms of Transaction Cost Theory, and pointed out that the relational contract is an effective organizational form in the LNG industry under the situation of high-degree of asset specificity and trading frequency. Taking the Dapeng LNG of Guangdong as a case of study, we analyzed the stock right structure of the LNG suppliers, LNG receiving terminals and transportation, and LNG users, thus to verify our theoretic analysis. In light of the experiences from the relational contracts in the global LNG trade, some suggestions are presented here as follows: (1)we should cooperate with foreign companies to take active part in the exploration and development of oil and gas resources by means of rational contracts with features of cross share-holding and capital infiltration; (2)we should enter into the mature oil and gas fields through the way of share subscription of stock right and joint ventures; (3)we should improve the domestic ener-gy market by introducing more foreign oil and gas companies.

    International Nuclear Information System (INIS)

    This paper presents an overview of the LNG industry in China, covering LNG plants, receiving terminals, transportation, and applications. Small and medium scale LNG plants with different liquefaction processes have already been built or are being built. China's first two LNG receiving terminals have been put into operation in Guangdong and Fujian, another one is being built in Shanghai, and more are being planned. China is now able to manufacture LNG road tanks and containers. The construction of the first two LNG carriers has been completed. LNG satellite stations have been built, and LNG vehicles have been manufactured. LNG related regulations and standards are being established. The prospects of LNG in China are also discussed in this paper. Interesting topics such as small-scale liquefiers, LNG cold energy utilization, coal bed methane liquefaction, LNG plant on board (FPSO - floating production, storage, and off-loading), and LNG price are introduced and analyzed. To meet the increasing demand for natural gas, China needs to build about 10 large LNG receiving terminals, and to import LNG at the level of more than 20 bcm (billion cubic metre) per year by 2020.

    基于API581的风险评估技术( RBI)是近年来石化行业逐渐采用并得到认可的一种新的评估设备经济可行性和安全性的技术。但是由于LNG的温度一般低至-162℃,使得LNG设备在应用API581时受到了限制。低温脆性断裂是LNG设备需考虑的一项主要的失效模式,API在评估脆断损伤因子时的温度范围是-73~38℃。为了能够评估LNG设备在低温环境下的风险,通过遗传算法将温度扩展至-209℃。扩展得到的脆断损伤因子曲线同夏比冲击试验的冲击功随温度变化曲线的趋势基本一致,因此扩展的损伤因子可以满足低温环境下LNG设备的风险评估。%Recently, Risk-Based Inspection ( RBI) technology based on API 581 has been gradually adopted and become a new technology to determine economic feasibility and safety of equipment in petrochemical plants.Howev-er, there are limitations of applying API 581 to LNG equipment because the temperature of LNG is usually under-162℃.Low temperature brittle fracture is a major failure mode of LNG equipment need to be considered, but API code considers the temperature range of about -73~38℃to evaluate the brittle fracture damage factor.To evalu-ate the risk of LNG equipment in low temperature environment, the temperature region was extended to about -209℃with genetic algorithm.The tendency of extended brittle fracture damage factor ( BFDF) curve was similar with the curve of impact energy against temperature change in Charpy impact tests.Therefore, the extend BFDF can satisfy the risk assessment of LNG equipment in cryogenic environment.

  1. 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

    2013-02-15

    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 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 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)

  15. 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.

  19. 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

    2007-01-01

    This study presents three kinds of skid-mounted plants, including single mixed refrigerant cycle (MRC), nitrogen expander cycle, and natural gas (NG) Claude cycle. Hysys simulation shows that single MRC is the most efficient cycle among the three. The specific power of single MRC liquefiers is 1 485 kJ/kg, 15% higher than that of large liquefaction process. Considering the recovery of stranded-gas, commercial analysis suggests that the initial cost of LNG plants ranging from 1 to 100 m3/day can be paid back in 2 to 4 years.

    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.

  3. 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)

  4. 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)

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

    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.

    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.

    Considering the operation security of LNG tank, it is very important to check the local strength of the LNG tanks under the action of sloshing load. As the efficiency of the operation can be highly improved by equaling the sloshing load to hull structure, through using the buffer coefficient to react the buffering effect, it is possible to do an analysis of the system of three different LNG tanks. With the further simplified model, buffer coefficient of the rolling and pitching condition can be obtained through calculation. The results can be referred if the LNG tank has similar specification and hull structure.%晃荡载荷作用下船体结构的局部强度校核,对保证 LNG 船营运安全非常重要。由于将液舱晃荡载荷等效到船体结构上可以极大程度提高局部强度校核的工作效率,以缓冲系数反映绝缘系统的缓冲效应,针对三艘 LNG 船展开分析,在对简化建模方法进一步讨论的基础上,通过计算得到了目标船绝缘系统在横摇和纵摇工况下的缓冲系数,研究成果可为相似规格,相近结构的 LNG 船晃荡强度校核提供参考。

  11. 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

  14. 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

    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.

  16. 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

This USD 3.9 billion LNG export project boasts the largest single foreign direct investment in Peru's history. A major component of the ...

  18. CFD Modeling of LNG Spill: Humidity Effect on Vapor Dispersion

    Giannissi, S. G.; Venetsanos, A. G.; Markatos, N.

    2015-09-01

    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.

  4. 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 recovery process of the liquefied natural gas requires low temperature cooling, which is typically provided by the vapor compression refrigeration systems. The usage of an absorption refrigeration system powered by waste heat from the electric power generating gas turbine could provide the necessary cooling at reduced overall energy consumption. In this study, a potential replacement of propane chillers with absorption refrigeration systems was theoretically analyzed. From the analysis, it was found that recovering waste heat from a 9 megawatts (MW) electricity generation process could provide 5.2 MW waste heat produced additional cooling to the LNG plant and save 1.9 MW of electricity consumption. Application of the integrated cooling, heating, and power is an excellent energy saving option for the oil and gas industry. (author)

    The support plates including all of the inner hulls such as E grade steel, weld seams and SUS304L were considered to establish the optimal stud welding condition in LNG ship building. The stainless steel plate was especially applied to the bracket on the liquid dome. The polished and etched surfaces of the welded stud and support plate were examined if the bead was properly formed. With the micrographic examination, the fusion boundary of metal weld zone formed by stud welding was analyzed to optimize the welding parameters. And also the analysis of the unacceptable welding faults such as cold and hot weld were performed. The mechanical tests such as tensile tests and bending tests were carried out to reveal any abnormal variation in the relationship of process parameters and the strength.

  8. 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

  9. Design optimization of ORC systems for waste heat recovery on board a LNG carrier

    International Nuclear Information System (INIS)

    Highlights: • ORC systems are one of the most promising options to recover low temperature heat. • Design of ORC systems on board a LNG carrier is optimized using the Heatsep method. • Simple, regenerative and two-stage, subcritical and supercritical ORCs are considered. • Three engine cooling systems layouts are found to supply heat to the ORCs. • The highest net power output is achieved by the two-stage ORC configuration. - Abstract: Organic Rankine Cycle (ORC) technology may represent an interesting way to exploit the low grade waste heat rejected by the ship power generation plant. This option is investigated here to recover the heat available from three of the four engines of a real electrically driven Liquefied Natural Gas (LNG) carrier. A detailed analysis of the engines operation is first performed to evaluate all thermal streams released by the engines. Heat associated with the jacket water, lubricating oil and charge air cooling of the engines is found to be available for the ORC, while the heat from the exhaust gases is already used to generate low pressure steam for ship internal use. Simple, regenerative and two-stage ORC configurations are compared using six different organic fluids that are selected as the most suitable for this application. The thermal matching that maximizes the net power output of the total system composed by engine cooling circuits and ORC cycle is then found by searching for the optimum heat transfer between thermal streams independently of the structure/number of the heat exchangers. Three layouts of the engine cooling systems are compared. Results show that the maximum net power output (820 kW) achieved by the two-stage ORC configuration almost doubles the simple cycle and regenerative ones (430–580 kW), but structure complexity and reliability issues may give different indications in terms of economic feasibility

    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。

    2015-01-01

    Hand-based biometric analysis systems and techniques are described which provide robust hand-based identification and verification. An image of a hand is obtained, which is then segmented into a palm region and separate finger regions. Acquisition of the image is performed without requiring particular orientation or placement restrictions. Segmentation is performed without the use of reference points on the images. Each segment is analyzed by calculating a set of Zernike moment descriptors for the segment. The feature parameters thus obtained are then fused and compared to stored sets of descriptors in enrollment templates to arrive at an identity decision. By using Zernike moments, and through additional manipulation, the biometric analysis is invariant to rotation, scale, or translation or an in put image. Additionally, the analysis utilizes re-use of commonly-seen terms in Zernike calculations to achieve additional efficiencies over traditional Zernike moment calculation.

  18. Modelling of Boil-Off Gas in LNG Tanks: A Case Study

    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.

    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)

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

    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.

    With the trend towards offshore LNG production and offloading, sloshing of LNC in partially filled tanks has become an important research subject for the offshore industry. LNC sloshing can induce impact pressures on the containment system and can affect the motions of the LNG carrier. The study first presented the details of a numerical model with Volume of Fluid (VOF) method; then the corresponding numerical simulation method to the sloshing characteristics in a LNG ship tank was given; finally, some simulation results were utilized to discuss some main parameters (such as the loading rate, the excitation frequency and the rolling angle amplitude) influencing the sloshing dynamic pressure characteristics. Based on the above contents, the LNG sloshing load characteristics and the corresponding measures for preventing the sloshing were given.%液舱晃荡引起的载荷己成为航行中载液船舶安全性评估的重要内容之一、以及船舶结构动力学的一个热点.文中首先运用VOF法建立LNG晃荡液舱模型,给出对LNG液舱晃荡特性数值模拟方法,运用模拟结果讨论不同工况(如装载率、频率、横摇角度幅值)下晃荡动压特性,在此基础上给出了LNG液舱的晃荡载荷特性与抑制晃荡的措施.

    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.

  8. LNG [liquefied natural gas]: Fueling energy demand in the Far East

    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

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

    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.

    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.

    2013-01-01

    Space mission architects are often challenged with knowing which investment in technology infusion will have the highest return. Certification-based analysis (CBA) gives architects and technologists a means to communicate the risks and advantages of infusing technologies at various points in a process. Various alternatives can be compared, and requirements based on supporting streamlining or automation can be derived and levied on candidate technologies. CBA is a technique for analyzing a process and identifying potential areas of improvement. The process and analysis products are used to communicate between technologists and architects. Process means any of the standard representations of a production flow; in this case, any individual steps leading to products, which feed into other steps, until the final product is produced at the end. This sort of process is common for space mission operations, where a set of goals is reduced eventually to a fully vetted command sequence to be sent to the spacecraft. Fully vetting a product is synonymous with certification. For some types of products, this is referred to as verification and validation, and for others it is referred to as checking. Fundamentally, certification is the step in the process where one insures that a product works as intended, and contains no flaws.

  14. LNG shipping at 50, SIGTTO at 35 and GIIGNL at 43. A commemorative SIGTTO/GIIGNL publication 2014

    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

    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

  14. Natural gas and CO2 price variation: impact on the relative cost-efficiency of LNG and pipelines.

    Science.gov (United States)

    Ulvestad, Marte; Overland, Indra

    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.

  13. Flexible LNG supply, storage and price formation in a global natural gas market

    Science.gov (United States)

    Hayes, Mark Hanley

    The body of work included in this dissertation explores the interaction of the growing, flexible liquefied natural gas (LNG) trade with the fundamentals of pipeline gas supply, gas storage, and gas consumption. By nature of its uses---largely for residential heating and electric power generation---the consumption of natural gas is highly variable both seasonally and on less predictable daily and weekly timescales. Flexible LNG trade will interconnect previously isolated regional gas markets, each with non-correlated variability in gas demand, differing gas storage costs, and heterogeneous institutional structures. The dissertation employs a series of analytical models to address key issues that will affect the expansion of the LNG trade and the implications for gas prices, investment and energy policy. First, I employ an optimization model to evaluate the fundamentals of seasonal LNG swing between markets with non-correlated gas demand (the U.S. and Europe). The model provides insights about the interaction of LNG trade with gas storage and price formation in interconnected regional markets. I then explore how random (stochastic) variability in gas demand will drive spot cargo movements and covariation in regional gas prices. Finally, I analyze the different institutional structures of the gas markets in the U.S. and Europe and consider how managed gas markets in Europe---without a competitive wholesale gas market---may effectively "export" supply and price volatility to countries with more competitive gas markets, such as the U.S.

    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.

    2016-10-01

    With the aid of cold energy from regasification of liquefied natural gas (LNG), freeze desalination (FD) is an emerging technology for seawater desalination because of its low energy characteristics and insensitivities to fouling problems. This work aims to investigate the major operating parameters of FD such as coolant temperature, freezing duration, supercooling, seeding, agitation, crystallizer material and subsequent washing procedure on ice production and water quality. It was found that the optimal freezing duration per batch was 1 h for an iron crystallizer and 1.5 h for a glass crystallizer. The optimal coolant temperature should be around -8 °C. The optimal amount of washing water to clean the raw ice was about 50 wt% of the raw ice. Over 50 wt% of the feed could be recovered as raw ice within 1 h, which means an overall ice recovery rate of higher than 25% (of the original seawater), considering the consumption of washing water. Both artificial and real seawater were tested under the optimized conditions. The total dissolved solid in the product ice was around 300 ppm, which met the World Health Organization (WHO) potable water salinity standard of 500 ppm. Therefore, the process parameters optimized in this study can be directly used for the freeze desalination of seawater.

  20. Geologic setting and gas reserves of the Venezuelan LNG project

    Energy Technology Data Exchange (ETDEWEB)

    Prieto, R.; Van der Molen, I.; Ramirez de Arellano, R. (Lagoven, Caracas (Venezuela))

    1993-02-01

    Four gas fields, Mejillones, Patao, Dragon, and Rio Caribe, were discovered by Lagoven, a subsidiary of Petroleos de Venezuela S.A., during an exploratory campaign during 1978-1982, offshore northeastern Venezuela. Thirteen wells drilled in the four fields discovered 13.9 tcf of gas, including 1.2 tcf of gas and condensate in the Rio Caribe field. In February 1991, Lagoven entered into an agreement with Shell, Exxon, and Mitsubishi to assess the viability of producing and exporting gas from the four offshore gas fields in the form of liquified natural gas. This is the Venezuelan LNG Project, otherwise called the Cristobal Colon Project. As part of the agreement the participants established a Project Team in Caracas and undertook the acquisition of 1600 km[sup 2] of 3D seismic data over the four fields to evaluate the geological model of the area. In addition, interpretation of the 3D data has led to a preliminary geological model for the gas bearing sands which envisages deposition in a regional setting varying from bathyal turbidites in the Rio Caribe and Mejillones fields in the west to shelf deposits over the Patao and Dragon fields in the east. In addition to the geological setting this paper will discuss preliminary results of the reserves evaluation for the Rio Caribe, Patao, and Dragon fields.

  1. Casting a cold eye on LNG : the real possibilities and pitfalls for Atlantic Canada

    International Nuclear Information System (INIS)

    The factors that drive the economic viability of a proposed liquefied natural gas (LNG) project in Atlantic Canada were discussed along with its impact on the region's energy future. The proximity of Atlantic Canada to the high-priced US northeast energy market and the accessibility of its ports gives the region a competitive advantage to become North America's first mover for LNG. Three proposed LNG projects in Atlantic Canada are located in industrial areas where local support is strong. The projects represent more than $5 billion in direct investment. These include the Irving Oil/Repsol terminal at Canaport in Saint John, New Brunswick; Anadarko's terminal at Bear Head, Nova Scotia and Keltic Petrochemical's proposed integrated petrochemical plant and LNG terminal at Goldboro, Nova Scotia. The market issues that must be addressed prior to any LNG project include long-term supply contracts, market response and pipeline capacity. The issues will ultimately be decided by markets and regulatory processes. This document emphasized the significance of the first-mover advantage, and noted that those who gain an early market share will profit from higher prices, access to better customers and potential economies of scale from a well-established presence. Short-term benefits include the jobs created by the construction and operation of a terminal, and the municipal tax revenues it would generate. Long-term benefits include transportation cost savings from pipeline expansion; access to additional gas supplies; and gains for regional prosperity. The final factors in support of LNG projects in Atlantic Canada include the need to strengthen trade ties with the New England States and access to the US gas markets. refs., tabs., figs

  2. Project risk perspective on using LNG, CNG, and GTL concepts to monetise offshore stranded gas

    Energy Technology Data Exchange (ETDEWEB)

    Danielsen, Hans Kristian; Blikom, Lars Petter

    2010-09-15

    This paper discusses technology maturity and the key risks involved in establishing LNG, CNG, and GTL value chains in order to monetise offshore stranded and associated gas. The paper uses Monte Carlo simulations to evaluate the economics of the various concepts and the impact of uncertainty. The conclusion is that LNG offers the most flexible value chain with the lowest level of risk exposure. CNG may offer better economics as long as the distance to market is fairly short. GTL must overcome significant technological challenges before becoming available for offshore use and also offers higher uncertainty in economic terms.

    2012-01-01

    Estimation of the parameters of an exponential distribution based on record data has been treated by Samaniego and Whitaker (1986) and Doostparast (2009). Recently, Doostparast and Balakrishnan (2011) obtained optimal confidence intervals as well as uniformly most powerful tests for one- and two-sided hypotheses concerning location and scale parameters based on record data from a two-parameter exponential model. In this paper, we derive optimal statistical procedures including point and interval estimation as well as most powerful tests based on record data from a two-parameter Pareto model. For illustrative purpose, a data set on annual wages of a sample production-line workers in a large industrial firm is analyzed using the proposed procedures.

    The commercialization of Liquefied Natural Gas (LNG) has been gaining great prominence worldwide and in Brazil, in recent days, due to the ever-increasing need for diversification of energy sources and for flexibilization of gas offer, in order to ensure the importing countries' supply. In this scenario, LNG has been positioning itself, around the world, as an important alternative, especially in cases where there is uncertainty concerning the fulfillment of delivery contracts, the transportation network is still incipient or inexistent, the gas pipelines operate at full capacity and the country's gas demand is met by more than one exporting source, sometimes by different transport modals. In the case of Brazil, the recent restrictions to the gas offer bring to the agenda the search for better solutions in energy policy in order to appropriately meet the totality of national demand. This article presents the current situation of the LNG market and identifies the main agents involved in its commerce, drawing attention to, in light of the originality of LNG projects in Brazil, the need for perfecting the regulation in order to boost the development of the national gas industry.

    Kim, Myung Hyun; Son, Young Joo; Kang, Sung Won; Lee, Jae Myung; Na, Sung Soo

    2006-03-01

    The aim of this study is to investigate dynamic failure initiation and failure modes of insulation panels of LNG carriers. Insulation panels of LNG cargo tanks may include mechanical failures such as cracks as well as delaminations within the layers due to impact sloshing loads and fatigue loadings, and these failures cause a significant decrease of structural integrity. In this study, a structural health monitoring system, employing fiber optic sensors is developed for monitoring various failures that can occur in LNG insulation panels. Fiber optic sensors have the advantage of being embedded inside of insulation panels. The signal of embedded fiber optic sensors is used to calculate the strain of insulation panels and is processed by digital filtering to identify damage initiations. It has been observed that the presence of defects and delaminations produce noticeable changes in the strain measurement in a predictable manner. In addition, fiber optic sensors are used to measure static and dynamic strain variations of insulation panels with and without damage. It is expected that this study will be used as a fundamental study for the safety assessment of the LNG insulation panels.

    Liquefied natural gas (LNG) transport carriers are exposed to a risk by the repeated bump in the LNG container during the vessel traveling over the wave in ocean. The liquid inside the container, especially when it was not fully contained, make a strong bump onto the insulation panel of the tank wall. The insulation panel consists of several layers of thick polyurethane foam (PUF) to maintain the LNG below the cryogenic temperature, -162°C. Due to the repeated shock on the PUF, a crack could be developed on the tank wall causing a tremendous disaster for LNG carriers. To prevent the accidental crack on the tank, a continuous monitoring of the strain imposed on the PUF is recommended. In this work, a fiber-optic Bragg grating was imbedded inside the PUF for monitoring the strain parallel to the impact direction. The optical fiber sensor with a small diameter of 125 μm was suitable to be inserted in the PUF through a small hole drilled after the PUF was cured. In-situ monitoring of the strain producing the change of Bragg reflection wavelength, a high speed wavelength interrogation method was employed by using an arrayed waveguide grating. By dropping a heavy mass on the PUF, we measured the strain imposed on the insulation panel.

    2013-01-01

    The ROOT based Offline and Online Analysis (ROAn) framework was developed to perform data analysis on data from Depleted P-channel Field Effect Transistor (DePFET) detectors, a type of active pixel sensors developed at the MPI Halbleiterlabor (HLL). ROAn is highly flexible and extensible, thanks to ROOT's features like run-time type information and reflection. ROAn provides an analysis program which allows to perform configurable step-by-step analysis on arbitrary data, an associated suite of algorithms focused on DePFET data analysis, and a viewer program for displaying and processing online or offline detector data streams. The analysis program encapsulates the applied algorithms in objects called steps which produce analysis results. The dependency between results and thus the order of calculation is resolved automatically by the program. To optimize algorithms for studying detector effects, analysis parameters are often changed. Such changes of input parameters are detected in subsequent analysis runs and...

    A nickel-phosphorus-alumina xerogel catalyst was prepared by a carbon-templating epoxide-driven sol-gel method (denoted as CNPA catalyst), and it was applied to the hydrogen production by steam reforming of liquefied natural gas (LNG). For comparison, a nickel-phosphorus-alumina xerogel catalyst was also prepared by a similar method in the absence of carbon template (denoted as NPA catalyst). The effect of carbon template addition on the physicochemical properties and catalytic activities of the catalysts in the steam reforming of LNG was investigated. Both CNPA and NPA catalysts showed excellent textural properties with well-developed mesoporous structure. However, CNPA catalyst retained a more reducible nickel aluminate phase than NPA catalyst. XRD analysis of the reduced CNPA and NPA catalysts revealed that nickel sintering on the CNPA catalyst was suppressed compared to that on the NPA catalyst. From H2-TPD and CH4-TPD measurements of the reduced CNPA and NPA catalysts, it was also revealed that CNPA catalyst with large amount of hydrogen uptake and strong hydrogen-binding sites showed larger amount of methane adsorption than NPA catalyst. In the hydrogen production by steam reforming of LNG, CNPA catalyst with large methane adsorption capacity showed a better catalytic activity than NPA catalyst.

  8. Feasibility of methods and systems for reducng LNG tanker fire hazards

    Energy Technology Data Exchange (ETDEWEB)

    1980-08-01

    In this program concepts for reducing fire hazards that may result from LNG tanker collisions are identified and their technical feasibility evaluated. Concepts considered include modifications to the shipborne LNG containers so that in the event of a container rupture less of the contents would spill and/or the contents would spill at a reduced rate. Changes in the cargo itself, including making the LNG into a gel, solidifying it, converting it to methanol, and adding flame suppressants are also evaluated. The relative effectiveness and the costs of implementing these methods in terms of increased cost of gas at the receiving terminal, are explained. The vulnerability of an LNG tanker and its crew to the thermal effects of a large pool fire caused by a collision spill is estimated and methods of protecting the crew are considered. It is shown that the protection of ship and crew so that further deterioration of a damaged ship might be ameliorated, would require the design and installation of extraordinary insulation systems and life support assistance for the crew. Methods of salvaging or disposing of cargo from a damaged and disabled ship are evaluated, and it is concluded that if the cargo cannot be transferred to another (empty) LNG tanker because of lack of availability, then the burning of the cargo at a location somewhat distant from the disabled tanker appears to be a promising approach. Finally, the likelihood of the vapors from a spill being ignited due to the frictional impact of the colliding ships was examined. It is found that the heating of metal sufficient to ignite flammable vapors would occur during a collision, but it is questionable whether flammable vapor and air will, in fact, come in contact with the hot metal surfaces.

  14. Reliability analysis of software based safety functions

    International Nuclear Information System (INIS)

    The methods applicable in the reliability analysis of software based safety functions are described in the report. Although the safety functions also include other components, the main emphasis in the report is on the reliability analysis of software. The check list type qualitative reliability analysis methods, such as failure mode and effects analysis (FMEA), are described, as well as the software fault tree analysis. The safety analysis based on the Petri nets is discussed. The most essential concepts and models of quantitative software reliability analysis are described. The most common software metrics and their combined use with software reliability models are discussed. The application of software reliability models in PSA is evaluated; it is observed that the recent software reliability models do not produce the estimates needed in PSA directly. As a result from the study some recommendations and conclusions are drawn. The need of formal methods in the analysis and development of software based systems, the applicability of qualitative reliability engineering methods in connection to PSA and the need to make more precise the requirements for software based systems and their analyses in the regulatory guides should be mentioned.

  18. LNG or not LNG?

    International Nuclear Information System (INIS)

    Despite the fact that Egypt now has excess to natural gas deposits in the Nile Basin and is keen to export, and that Turkey is keen to import gas from non-Russian sources, the solution of supplier meeting demand is fraught with political wrangling. Political unrest in the Middle East makes an overland pipeline unacceptable. Gas production companies, such as Italy's ENI and AMOCO from the USA are suggesting other routes for Egyptian gas to reach Turkey, such as a subsea pipeline or transfer by sea using tankers, after the fuels conversion to Liquefied Natural Gas. Both companies are linked closely with the exploitation of Nile Delta gas resources and the future is, as yet, unclear. (UK)

  19. The influence of the technologically advanced evacuation models on the risk analyses during accidents in LNG terminal

    International Nuclear Information System (INIS)

    The evacuation of people located in different safety zones of an LNG terminal is a complex problem considering that the accidents involving LNG are very hazardous and post the biggest threat to the safety of the people located near the LNG leakage. The safety risk criteria define the parameters which one LNG terminal should meet in terms of safety. Those criteria also contain an evacuation as an evasive action with the objective to mitigate the influence of the LNG accident on the people at risk. Till date, not a lot of attention has been paid to technologically advanced evacuations intended for LNG terminals. Creating the technologically advanced evacuation influences directly on the decrease of the probability of fatalities Pf,i, thus influencing the calculation of the individual risk as well as the societal risk which results in the positioning of the F-N curve in the acceptable part of the ALARP zone. With this paper, we aim to present the difference between the safety analyses in cases when conservative data for Pf,i is being used while calculating the risk, and in cases when real data for Pf,i is been used.

    Said A. Shaar

    2006-01-01

    Full Text Available This study introduces an analysis to the performance of the Enhanced Associativity Based Routing protocol (EABR based on two factors; Operation complexity (OC and Communication Complexity (CC. OC can be defined as the number of steps required in performing a protocol operation, while CC can be defined as the number of messages exchanged in performing a protocol operation[1]. The values represent the worst-case analysis. The EABR has been analyzed based on CC and OC and the results have been compared with another routing technique called ABR. The results have shown that EABR can perform better than ABR in many circumstances during the route reconstruction.
