LR Awards AIP for GTT Bunkering Concept

 

GTT, a designer of membrane containment systems for the maritime transportation and storage of liquefied natural gas (LNG), announced that it has received an Approval in Principle (AIP) from classification society Lloyd's Register for its 4,000 m3 bunkering ship concept, using Mark III Flex Cargo Containment system and operating with a vapor pressure of up to 2 barg.  

 

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 said it is now working on similar studies using NO 96 technology and also for applications on LNG-fuelled vessels.

 

“We have demonstrated the reliability of our systems to operate beyond atmospheric pressure applications,” said Philippe Berterottière, Chairman and CEO of GTT. “I believe this new development by GTT, in response to the market requirements, will contribute positively to an efficient LNG as fuel supply chain, and therefore to the growth of LNG as marine fuel market.”
