Qatargas LNG is embarking on an ambitious expansion project which involves building four mega LNG Trains, each with a capacity of 7.8 MTPA. The offshore facilities will include 6 wellhead platforms and 63 wells with each well capable of producing 100 MMSCFD of gas. The onshore facilities will include inlet reception, utilities, four LNG trains, and six Sulfur Recovery units. Common facilities will include five LNG storage tanks of 140,000 M3 capacity, three berths, and a 12,000 T/day common sulfur storage and loading facility. When competed, these facilities will take Qatargas from its current three train LNG output of 10 MTPA to 44 MTPA by the year 2012.
Qatargas launched the Expansion Start-up (ESU) organization in September 2006 to start-up these expansion projects. The mission of this organization is to support the pre-commissioning and commissioning activities and to execute a flawless start-up for each of the new facilities. The ESU organization will also prepare these facilities for future routine operations and capture lessons learned to assist in future projects and start-ups.
This paper discusses the challenging tasks ESU has faced, and still progressing, to ensure these mega trains and associated facilities start up safely and achieve their required performance expectations.
Mr. Ahmed Shehata working in ELNG as Operations Director, joined ELNG in 2004. Used to work in Production Division of ADGAS Company for almost 24 years. ELNG is keen in implementing the sustainable development approach in all its operations. ELNG has settled a new world record by using a rapid commercialization process which lead to move from EPC award to first LNG in around 4 years as shown on the BG Capital and cost comparison (see below chart). The ELNG plant, located at Idku, is an innovative structure that allows third parties to invest in future LNG production trains at the site. Ahmed will discuss the background and project highlights of the plant. Whilst touching upon the challenges for hiring high skilled staff, and carrying out an integrated training program in order to transfer successful technology and development of local employees. ELNG poses security risk and control in three areas (inside and outside plant fence and marine), this will be discussed as well as how ELNG achieve high safety performance. And not the last the presentation will show how Idku LNG Port is one of the world's most modern LNG exporting facilities in which Port operations deliver Safe, reliable, cost-effective and efficient marine services backed by experience, expertise and constant dedication to Egyptian LNG needs. Finally Mr. Ahmed will review the major issues and lessons learnt from the plant and will asses Egyptian LNG present and future.

His overriding occupation since almost two and a half years is the planning and implementation of EconGas’s LNG ambitions. Rudolf will adress the LNG pricing issue, which is an increasing issue in the LNG Industry. How to get it right in a volatile energy market? He will discuss if emerging spot pricing a viable trading strategy in the global LNG marketplace; he will evaluate the globalisation of LNG prices and their impact on pipeline prices and look at the understanding of the buyer's perspective of increasing high LNG prices and their impact on new entrants
Gazprom has developed the Company’s operating strategy for LNG production and sea-borne transportation. In 2005 Gazprom supplied its first LNG cargo to the USA followed in 2006 by the Great Britain, Japan and South Korea. Entering the Sakhalin – 2 project in 2007 proved to be a serious step on Gazprom’s way to the global liquefied natural gas market. Since almost all the volumes of natural gas to be produced within the Sakhalin – 2 project are contracted, Gazprom has secured its future status as a key supplier of energy resources to the countries in the Asian and Pacific Region and North America. Total and StatoilHydro were selected to become Gazprom’s partners in implementing the project for the development of the Shtokmanovskoye gas condensate field. This field will become a resource base for Russian natural gas supply to the countries in the Atlantic Basin both through pipelines and by using LNG technologies.
Wim Hoebee
Head of Shipping, Port Planning & DevelopmentPORT OF ROTTERDAM AUTHORITY
The Netherlands
Safety and security are key factors in the design and lay-out of both planned LNG marine import terminals in the port of Rotterdam; in particular much attention needs to be paid to the nautical safety aspects. Two LNG terminals needed to be fitted in limited available space and in a busy shipping area: innovative terminal configurations are the result. Rotterdam is a busy port: many vessels carry dangerous goods. However, LNG will be a new trade in Rotterdam. For this reason, particularly in the initial phase, extra attention will be paid to dealing with LNG shipping. Important criterion for the safety and admission policy for LNG carriers will be that this policy should be in line as much as possible with the existing admission policy for ships carrying dangerous goods (in bulk). Specific studies with regard to LNG vessels showed that crossing traffic at high speed should be avoided. This conclusion is leading for the development of the nautical admission policy. To achieve above mentioned goals a growth model for admission policy will be applicable

Common Elements of Successful LNG Projects Using the Optimized CascadeSM Process The ConocoPhillips Optimized CascadeSM process has been used in nine LNG projects throughout the world. All nine projects have been highly successful in that they were completed on or ahead of schedule, within budget and immediately after commissioning produced LNG at rates greater than design. The plants continue to run at greater than design capacity with high availability and high production efficiency with less than design fuel rates. This presentation reviews the common elements or factors which lead to successful LNG projects. These elements include selecting an LNG liquefaction technology that is well-proven, and simple to operate, (using technology that allows using multiple commonly available pieces of equipment from multiple suppliers), yet incorporates innovations. The two-trains-in-one design provides high availability and production efficiency by providing operator flexibility and operating equipment redundancy. Also critical to the success of a project is an EPC contractor that has a demonstrated track record of safely completing large, complex projects on time and within budget despite difficult work conditions. A short schedule is important to the economics of these costly projects, so a contracting philosophy that minimizes project schedule and provides incentives for the desired results is important to their success. A close and proven working relationship between the technology provider and contractor for operator training, commissioning and optimization of the plant operations is critical to the long term success. Specific examples from past projects and their application to future developments, including floating LNG will be discussed.

World LNG production has grown by 55% in five years. “Global” exchanges of LNG cargoes have been accelerated, as cargoes are transported to destinations sometimes different from the originally assumed ones. New LNG importers are emerging in South America, Canada, Southeast Asia, and the Middle East. An unprecedented major expansion is underway globally both for liquefaction and regasification. As the expansion is unbalanced, regasification capacity is likely to be underutilised relative to liquefaction. After only one final investment decision was made in liquefaction in 2006, three such decisions were made in 2007. There are indications of project delays across the industry caused by skilled labour shortages and higher engineering costs. Even when projects start operations, initial troubles, as well as occasional shortage of feedgas, often prevent them from producing at design capacity. Having production capacity no longer means actual production as was the case 10 years ago.
The development of offshore LNG projects is partly based on the ability of LNG industry actors to bring innovative solutions capable of meeting new technical requirements linked to the marine environment. Whether for the LNG export or receiving facilities, it appears that the transfer link is a key element and the development of an efficient and safe LNG transfer system must contribute to guarantee the availability and flexibility of these new offshore LNG chains. Several offshore LNG transfer solutions are under development, and cryogenic flexible hose based LNG transfer systems appear to be able to meet offshore constraints and the LNG Industry requirements. However, LNG operators will be convinced by those technology developments only after industrial qualification and validation of performances, reliability, safety and operational limits of new LNG transfer systems A LNG transfer system designed for onshore and offshore conditions, and composed of a 16’’ flexible hose and a multi-purpose connecting system, have been tested in the context of an existing LNG receiving terminal in Montoir de Bretagne. These full-scale LNG trials were the ultimate stage of an industrial qualification process and they have been carried out on a dynamic test bench able to reproduce harsh open sea conditions. All operational procedures for all phases related to the use of this offshore LNG transfer system have also been validated through those full-scale LNG tests, which means that this transfer system is now ready for commercial projects.

For two years, he led a team in charge of the coordination of SAIPEM development activities related to liquefied gases, especially LNG storage systems and offshore LNG facilities, before being in charge of Risk Assessment and value engineering during the tender for the EPC of an onshore LNG plant. Within the Floating Facilities Business Unit of SAIPEM, he is now in charge to coordinate activities related to Floating LNG projects. Nicolas will be presenting a paper on Floating LNG plants: technologies and application cases
Currently the interest for producing gas in remote arctic areas has greatly increased. To transport the gas to consumers, one alternative to pipeline would be to use LNG Carriers. Recently, the successful development of highly capable and effective ice breaking ship solutions as well as that of very large LNG carriers has created an opportunity for the development of large size icebreaking LNG Carriers. So far LNG transport in ice covered areas is made with small size vessels and under reasonably light ice conditions. The development of a LNG Carrier capable of safe and economical operation in Arctic waters is a challenge. By using the latest technologies and recent experience, Aker Arctic and GTT have built up a design and development program which resulted in a highly ice capable large size (224 000m3) arctic LNG Carrier solution. The development of the technical design included different variations and solutions for icebreaking operation. The ship conceptual designs were created for the NO96 membrane type LNG cargo containment system and preliminary estimates and calculations including hull and containement system integrity were carried out for the demanding ice conditions of the Kara Sea.

Chris Frail is the global Liquid Flow Meter General Product Manager at GE Sensing located in Billerica, MA. He is responsible for the company's line of ultrasonic clamp-on and wetted solutions for liquid applications including high temperature oils and cryogenic liquids. He has over 10 years experience in Applications Engineering and Product Management in ultrasonic flow meter technologies. Previous positions include Applications Engineer, Field Services Team Leader, DMAIC Black Belt, and Product Manager.
This workshop covers ultrasonic flow meters as applied today, to measurement of the flow rate of LNG as well as other applications at production facilities and receiving terminals. The workshop focuses on a method of addressing the issues created when measuring fluids at low temperatures. Calibration of these flow meters without access to cryogenic facilities is discussed. The workshop will also cover buffer technology as an effective way to protect critical components of ultrasonic flow meter systems. Buffer technology allows the meter to operate without maintenance or failure at cryogenic temperatures over long periods of time.
The rapid expansion of the LNG market has resulted in interactions between established and emerging markets and players. Changing trade patterns, term deals and spot deals have generated greater scrutiny of custody transfer quantities than before. As the LNG market expands and the skill shortage becomes more apparent, operators relying on push-button technology may not be detecting financially significant errors. The custody transfer process involves calculation of a delivered energy value from measured volumes and composition, which depends on sample and analyser accuracy. Equally, the use of weathering models to monitor composition continuity during storage and transport relies on many assumptions, notably that the original composition is correct. Correlation studies can eliminate instrument bias and confirm analyser performance. However, delivery of a representative sample is crucial and this step in the process appears to have the fewest controls and loosest adherence to standards and norms. It seems that sampling systems have low priority in LNG import/export terminals. For example, we have seen sampling systems which show a 5% fluctuation in methane content. For a 138,000 cubic metre cargo, this equates to an energy difference of around 79,000 mmBTU, $575,000 (based on HH price of $7.4 per mmBTU). It is critical for sampling systems to be robust and follow standards such as ISO 8943 rigorously. Without this, there will always be uncertainty over custody transfer quantities and one or other of the trading partners may lose out substantially.
Raul Risi is currently project manager in Offshore LNG. He joined Technip in 1992 and spent 12 years in the Process and Technology Division as a process and principal engineer on LNG and gas projects. Since 2004, he has been actively involved in the development and certification of the cryogenic PiP and is the author or co-author of several papers on Offshore LNG technologies. Raul's paper highlights the project readiness level of the development and certification status related to the Cryogenic Pipe-in-Pipe (C-PiP) technology developed by Technip. CAPEX and OPEX reductions, allowed by the integration of the C-PiP into LNG plants and LNG terminals, are detailed. A particular accent is put on the liquefaction production increase though boil-off gas reduction. Beyond economic considerations, the C-PIP technology also allows coping with specific project constraints in terms of safety, security, environment, impact on local communities and line routing.

Various studies of industry practices have demonstrated that improving basic engineering workflow and electronic data flow can have dramatic impacts on large capital projects, such as typical LNG plants. There are several factors at work. First, communication of engineering information at early stages of project development to the cost estimation function, enables better business decision making based on more accurate project economics. Second, concurrent basic engineering based on use of advanced basic engineering tools (Such as Aspen Basic Engineering) has been proven to cut down project timescales by up to 30%. Third, linking together of different engineering tasks through use of a central project database facilitate the engineering change process, improving design flexibility and optimization. Finally, such integrated tools enables sharing of large engineering projects across multiple design centers and between several EPC project partners. This paper will discuss how these can be achieved, drawing on specific project examples from REPSOL, Worley Parsons, Jacobs Engineering and JSR.

2007 speakers included:
The LNG Tank Technology Center has been providing LNG-related research and development, engineering design, technical consulting and commissioning services based on the technology and know-how it has obtained through continuous development over the last 15 years. They have recently developed an alternative membrane system after several years of development. Young-Myung Yang will discuss recent developments in containment systems, safety and security issues concerning storage of LNG as well as presenting details of their alternative membrane system.
Today's LNG industry is faced with an ever increasing diversification of LNG supply sources, leading to growth in worldwide LNG trade as well as a multiplication of the different LNG qualities which can be exchanged. Import terminals are often faced with the need to handle different LNG qualities concurrently in the same storage tanks. This can impose constraints on the operations, such as production of high boiloff rates during tank filling operations. This can also increase the risk of creating stratifications resulting from the incomplete mixing of cargo and heel LNGs. Gaz de France, in collaboration with other companies, has developed tools and procedures which help to be better prepared in dealing with these emerging challenges. This presentation will highlight various methods showing the benefits which can be reaped and operational flexibility which can be gained from a better understanding of LNG behaviour in storage tanks involving the mixing of different LNG qualities in a same tank.
ELNG is keen in implementing the sustainable development approach in all its operations. The ELNG plant, located at Idku, is an innovative structure that allows third parties to invest in future LNG production trains at the site. Ahmed will discuss the background and project highlights of the plant. Whilst touching upon the challenges for hiring high skilled staff, and carrying out an integrated training programme in order to transfer successful technology and development of local employees. ELNG poses security risk and control in three areas (inside and outside plant fence and marine), this will be discussed as well as how ELNG achieve high safety performance. Finally Ahmed will review the major issues and lessons learnt from the plant and will asses Egyptian LNG present and future.
Provalys and Gaselys, ordered by Gaz de France and by a NYK-Gaz de France joint venture are today the biggest LNG carriers in operation with a capacity of 154 500 m3. They were delivered by Chantiers de l'Atlantique, St Nazaire, France in November 2006 and March 2007. This paper will outline the innovative aspects of these ships regarding: Transport technology, with the storage tank insulation technique, power technology, with diesel/gas electric propulsion system, and the safety and environmental philosophy which benefits from the propulsion system choice. These two ships retrieve the same technological options as their elder brother, the 74 000 m3 Gaz de France energY LNG tanker, the first to have been ordered by Gaz de France to Chantiers de l'Atlantique.
Offshore liquefaction has facilitated recent new technology developments in process and equipment. Design considerations for the developments of offshore liquefaction technology will be addressed. These considerations are for the developments of technologies for the liquefaction process and equipment, with considerations in safety. Important areas are the effects of motion, operational flexibility and availability of the plants, safety concerns due to the congestion of areas in the offshore facilities, and transfers of LNG between offshore facilities to LNG ships. Process efficiency is less important than process simplicity and overall safety. Safety considerations on the plant layouts, spacing and level of risks are important and offshore LNG transfer needs to meet the marine and environmental challenges.
The act of transferring cargo from one ship to another has been carried out since the earliest days or maritime trade. Today many different cargoes are routinely transferred from one vessel to another. In the U.S. Gulf of Mexico over 35% of the imported crude oil is handled via STS transfer. LPG products are routinely delivered via STS transfer. In the US 1,300 to 1,500 STS operations are conducted annually. However until recently the transfer of LNG from one ship to another has only been carried out in response to some sort of casualty. With the ever growing fleet of LNG ships in operation and the rapidly emerging spot trading of LNG the use of ship to ship transfer for commercial purposes is becoming a reality for the LNG industry. Utilizing STS transfer for commercial purposes should only be carried out after a careful and deliberate development process that is based on a risk based approach addressing all aspects of the equipment and operation. This presentation is a case study of the process that Excelerate followed in the development of the STS transfer operations being carried out to deliver LNG on conventional LNG ships to our LNG regasification vessels for ultimate delivery into Excelerate network of Energy Bridge ports.
Gas is destined to play a vital role in the world’s future energy supply, and as such will also be a major driver of economic growth and sustainable development in Nigeria. Dr Amikiri will evaluate the operations, maintenance and safety of liquefaction trains to enhance the production and reliability of the plants performance, whilst discussing the latest developments of LNG in Nigeria.

Shell believes that the projected growth in LNG markets will translate into a demand for larger train sizes. This is primarily driven by economies of scale in terms of equipment costs, construction costs and project management. We present here a new design for a large train producing LNG in the range of 6 to 11 Mtpa. The design is based on Shell’s Parallel Mixed Refrigerant process, includes CO2 and sulphur treating, and will be flexible to reach heating values down to typical US specifications. Using large yet fully developed and proven gas turbines, and other key equipment, maximizes economies of scale. Care has been taken to retain multiple sourcing options for all equipment. Steam is used to integrate heat generation and demand plant-wide; this includes the waste heat recovery from the gas-turbine drivers, co-firing, and heat demand of the energy intensive treating train and heat production by the sulphur-recovery unit. The heat recovered is utilized for process heating and to produce mechanical and electrical power. The full utilization of waste heat from the gas-turbine exhausts enables a step-change in plant efficiency and reduces the specific CO2 emissions considerably, compared to conventional LNG plant design. In an interesting heat integration arrangement the capacity of 6 to 11 mtpa can be achieved with two gas turbines.
Potential delays in permitting and uncertainty in future energy demand have caused utilities and energy companies to reconsider large capital expenditures for land based LNG receiving terminals. A less costly option that can expeditiously bring gas to market is the offshore FSRU ( floating storage regasification unit) Concepts vary from purpose built Regas vessels which discharge vaporized gas through an STL (submerged turret loading) system while maintaining the ability to trade using conventional midship manifolds, to converted existing LNG carriers fitted with vaporizers that are either attached permanently to a buoy or moored at a berth fitted with a high pressure gas discharge line. The technical and commercial ramifications associated with each concept must be evaluated against the project parameters to find the best solution while never compromising the unparalleled safety record in the LNG industry.
This presentation concerns an innovative approach to the analysis of nautical and external risks related to the traffic of LNG-carriers. The planned LionGas Terminal is an initiative of 4-GAS, which aims to have the terminal operational in 2009/2010. In view of the high traffic density in this part of Port of Rotterdam and the relative proximity of residential areas, the existing risk assessment methods did not give sufficiently accurate results. Hence a new fully quantitative approach was devised by the team comprising 4-GAS, Royal Haskoning and MARIN/MSCN. This presentation discusses the steps taken to generate a fully quantitative approach, consisting of accuracy and reliability of the risk analysis.
Neil will join Henk Smith from Rovsing to present on the latest findings of the BP Netherlands offshore facitility. Many companies face the challenge of reducing cost and improving operations, and want to turn to asset management. In practice, however, many struggle with implementation and high costs, and do not obtain the anticipated value. A practical approach will help achieve results within short time. BPNE faced this challenge, operating a mature gas field with constant need for cost reduction while maintaining availability on-demand. To manage the asset it is paramount to identify processes that lead to reduced reliability, availability and capacity. A practical approach was taken to meet management objectives. Henk will describe the improvement process and results achieved the first 2 years.
Frans is the Project Development manager at Essent Energy. His presentation will be a case study on the Eemshaven regas terminal project that Essent are involved in. He will touch upon the status of the project, what's happening at present, the developments that have been made since it's beginning and overcoming the challenges they had along the way. Finally focussing on the future of the project.
Ofgem is the economic regulator of gas and electricity industries in Great Britain. As part of our statutory duties, we work to ensure that LNG regasification terminals are operated in a manner which is not harmful to competition in the energy markets. European legislation contains a requirement to enable non-discriminatory third party access to LNG importation terminals. In our presentation we will be explaining the way in which this requirement has been implemented (and lifted as necessary) in GB. Attention will be paid to the impact of the current regulatory setting on the development of new LNG technologies.
This workshop covers ultrasonic flow meters as applied today, to measurement of the flow rate of cryogenic LNG as well as other applications at production facilities and receiving terminals. The workshop focuses on a method of addressing the issues created when measuring fluids at low temperatures. Calibration of these flow meters without access to cryogenic facilities is discussed. The workshop will also cover buffer technology as an effective way to protect critical components of ultrasonic flow meter systems. Buffer technology allows the meter to operate without maintenance or failure at cryogenic temperatures over long periods of time.
New LNG technologies have been developed to lessen environmental impacts, while at the same time reducing costs of regasification. LNG Smart® Air Vaporization (SAV) process economically regasifies LNG and at the same time reducing fugitive emissions. It utilises ambient air, has no harmful effects on marine life, uses commercially available equipment, is applicable to onshore and offshore and produces fresh portable water as a byproduct. The process, at design ambient conditions of 15.6C (60F) and 80% relative humidity, provides all the heat required to vaporize the LNG, dramatically reducing air emissions and lowering fuel gas consumption by as much as 100%. The process is now being installed at the Trunkline LNG Infrastructure Enhancement Project at Lake Charles, LA.
Major developments are underway to exploit natural gas reserves as the demand for LNG continues to grow. The processing capacity of liquefaction facilities have increased due to continual improvements in gas processing technologies. Both conventional and future E-Drive approaches increase the demands on the local on-site power generation and require a larger and more complex electrical power distribution system. The supporting electrical power systems for future LNG liquefaction facilities will therefore be a much more significant factor in the overall design of the LNG plant. This paper describes the experience in performing electrical power system studies and indicates where this specialist knowledge has been crucially and successfully applied to the design of present and future LNG liquefaction facilities.
Many companies face the challenge of reducing cost and improving operations, and want to turn to asset management.

TORP Technology and its affiliates have spent almost 7 years and more than 40.000 man-hours of engineering, developing the HiLoad Technology. The HiLoad is now being selected for three offshore receiving and regasification terminals, and more projects are being considered worldwide. The HiLoad is also being evaluated as a key component in LNG loading and liquefaction projects on several gas fields being developed. Because of its novel, but simple, compact design, the HiLoad offers major cost advantages, higher operational flexibility and additional safety features compared to other technologies.
After a description of the main trends of the LNG industry, this presentation will focus on the role a classification can have and the contribution it can bring towards the maintenance of the safety and the reliability of the LNG shipping industry together with the major stakeholder of this industry.
LNG vapor dispersion calculations are a requirement for the siting of LNG terminals worldwide, either through specific prescriptive regulations or as part of an overall risk assessment for the LNG terminal. These calculations have thus far been performed with integral models which, although simple to use, are limited in their range of applicability. Recent work has been completed to validate the use of a commercial computational fluid dynamics (CFD) model, to accurately predict the dispersion of an LNG vapor cloud generated by a spill into an impoundment. The use of this CFD model allows the industry to perform more realistic vapor dispersion calculations, taking into account the vapor holdup provided by impoundment walls and the mixing effect of obstructions such as storage tanks. This allows the industry to perform the vapor dispersion calculations under a more realistic set of assumptions, resulting in less demanding siting constraints. This presentation will discuss the CFD validation results and provide guidance on the implementation of CFD for LNG vapor dispersion calculations.
The risk associated with a large scale spill of LNG over water, as a result of an LNG carrier tank breach, is a highly debated topic in the LNG industry and scientific communities, due primarily to the lack of information applicable to this type of scenario. A joint industry-sponsored project is currently underway to obtain quantitative information on the behavior of cryogenic spills onto water. The study is aimed at improving the understanding of phenomena such as cryogen-water friction, turbulence and heat transfer, and of the effect on pool growth of parameters such as water temperature, salinity and spill size. This presentation will discuss preliminary results from cryogenic spills onto water in a circulating water channel and will discuss the impact of the new findings on currently used models for LNG pool growth.
The presentation will point out the way Gaz de France uses LNG fire simulation tools and how these tools are recognized by different actors. Several videos of tests conducted by Gaz de France will be presented, illustrating the physical behavior of large LNG pool fire fires, as well as LNG vapor cloud fires with regard to the cloud concentration. Different approaches to study large fires will be commented, with a discussion on the types of models and the agreement of numerical simulations with experimental results.
The LNG industry is experiencing an unparralelled boom in demand which economists predict will continue well into the future. For existing LNG re-gasification terminals there is a need to operate as close to capacity limits and thus maximize returns on the current assets. whilst for planned terminals there is a need to ensure that the large investments planned produce the expected returns. Cost effective project execution is assisted by the a single Main Automation Contractor (MAC). In today's uncertain environment there is a heightened need for increased safety and security (both physical and cyber) measures to be an integral part of such solutions. It is also essential that personnel are correctly and sufficiently trained well in advance on appropriate simulators. The key to ensuring overall success in this is the use of a holistic automation solution approach which ensures effective integration of workflows and technologies, including field-to-ERP integration.
As an alternative to the expansion of onshore LNG import terminals Excelerate Energy, in cooperation with Exmar, Daewoo Shipbuilding Marine Engineering (DSME) and Applied Production and Loading (APL) have developed the “Energy Bridge™ Regasification Vessel” (EBRV) which is an innovative concept and design allowing a purpose-built LNG carrier to regasify the LNG on board and discharge the high pressure gas product directly into a natural gas pipeline distribution system through either a dedicated mooring arrangement with subsea high pressure pipeline, known as an Energy Bridge™ Deepwater Port, or a land-based high pressure gas receiving facility, known as an Energy Bridge™ GasPort. There are currently three of these unique EBRVs in service with five more on the new building ways and two Energy Bridge™ ‘Ports’ in service with one more under construction and many more in various stages of planning. The use of a number of proven technologies in this new Energy Bridge™ application has shown to be a promising, innovative means of introducing new sources of natural gas into the global gas infrastructure while providing a high degree of safety, reliability and function. The requirement for safety, reliability and function are the key drivers to the commercial success of the Energy Bridge™ endeavor in all regards of shipboard regasification and operations. The EBRV employs a number of redundant safety systems which are similar to those employed at shore-based facilities, that is, proven technology in a new application. This presentation is a study of the regasification safety case from a risk-based perspective and the mitigations put in place to reduce the perceived risk to ALARP levels.
