GTT of France said it has received an approval in principle from Lloyd’s Register, for its 4,000 cbm bunkering ship concept.
The concept is using Mark III Flex cargo containment system and it is operating with a vapour pressure of up to 2 barg.
“ Increasing the upper limit on the pressure up to 2 barg gives more operational flexibility allowing a more flexible boil off gas (BOG) management during loading and bunkering operations ,” GTT said in a statement.
According to GTT, 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, improving the holding time when there is no BOG consumption and reducing the use of any possible reliquefaction plant ,” the company added.
GTT is now working on similar studies using NO 96 technology and also for applications on LNG fuelled vessels.
