GTT, the world leader in the design of membrane containment systems for the maritime transportation and storage of LNG (Liquefied Natural Gas), announces that it has received a second Approval in Principle (AIP) for its 4,000 m3 Bunkering Ship concept, using Mark III Flex Cargo Containment system and operating with a vapour pressure of up to 2 barg. Following one delivered by Lloyd’s Register, this new AIP was received from the classification society, Bureau Veritas, after several months of a joint research and innovation program.
As a reminder, increasing the upper limit on the pressure up to 2 barg gives more operational flexibility. It allows a more flexible Boil Off Gas (BOG) management during loading and bunkering operations. Thanks to the pressurized membrane tank, the duration of bunkering operations are also optimized by increasing loading flow rates. Lastly, during voyage and stand-by mode, the time before gas pressure reaches the upper limit is longer. This improves the holding time when there is no BOG consumption and reduces the use of any possible reliquefaction plant, thereby diminishing costs. GTT is now working on studies based on NO 96 technology and also for applications on LNG Fuelled Vessels.
Philippe Berterottière, Chairman and CEO of GTT commented: “Obtaining a second AIP for this 2 barg application is a great success. GTT is in a constant search for novelty in order to help its clients in maximizing their operational flexibility. This new development in the application of our membrane containment systems is an important milestone for the LNG as marine fuel market and we look forward seeing the concept come into practice”.
