GTT’s 4,000 cbm bunkering ship concept, using Mark III Flex cargo containment system received its second approval in principal, the French company said in a statement.
The vessel operating with the vapour pressure of up to 2 barg received the AIP from Bureau Veritas adding to the one previously received from Lloyd’s Register, according to GTT.
“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,” GTT said.
The designer of membrane containment systems, that is currently working on studies based on NO 96 technology, said the pressurized membrane tank enables the optimization of the bunkering operations duration by increasing loading flow rates.
“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,” GTT concludes.
