Sept 20 (LNGJ) - GTT, the French maritime LNG storage technology company, said it recently received general approval from the American Bureau of Shipping, the US classification society, for its newest version of the Mark III Flex tank with a lower boil-off rate of gas. “This latest variant of the sea-proven Mark III Flex technology benefits from an improved insulation performance through an increase in thickness and an enhanced secondary membrane solution,” said GTT. The company said the new tank has a daily boil-off rate of 0.07 percent volume per day compared with 0.085 percent volume per day for the previous version.
