Leading technology for next generation of LNG carriers

Leading edge research to support the LNG industry with emerging technologies makes the next generation of very large LNG carriers a safe reality. With the global market for LNG growing at more than three times the growth rates for oil or traditional gas markets, operators are continuously looking for efficient and safe ways for containing, transferring and transporting LNG. LNG carrier design issues and technology innovations in LNG transport have resulted in an influx of new LNG carrier contracts in the last two years. The advanced technology can permit the approval of new LNG designs for a 40 year fatigue life, partial loading and strength assessment of the insulation in membrane type containment systems that have been a key issues in LNG technology. Sloshing is of particular importance as the membrane-type containment systems must be designed to withstand dynamic loads and sloshing pressure of the LNG when the tank is partially filled. This research has allowed owners, builders and designers to move forward in a safe yet commercially viable way as designers develop the next generation of LNG carriers that exceed 200,000m(3). Advancing industry knowledge drives to the other key technical areas such as a new concept of tank design, vibration analysis and fatigue assessment of containment system. Through an overview of recent projects currently being undertaken collaborating with industries, the most critical areas in LNG technology are presented for development of the next generation of large LNG carrier and offshore LNG terminal.
