Q-Flex is a type of ship, specifically a membrane type liquefied natural gas carrier.
Q-Flex vessels are propelled by two slow speed diesel engines, which are claimed to be more efficient and environmentally friendly than traditional steam turbines.[1][2] Q-Flex carriers are equipped with an on-board re-liquefaction system to handle the boil-off gas, liquefy it and return the LNG to the cargo tanks.[3] The on-board re-liquefaction system reduces LNG losses, which produces economic and environmental benefits. Overall, it is estimated that Q-Flex carriers have about 40% lower energy requirements and carbon emissions than conventional LNG carriers.[4]
The capacity of a Q-Flex vessel is between 165,000 m3 and 216,000 m3.[5] Until the entry into service of the Q-Max-type carrier, it was the world's largest LNG carrier type with a capacity of 1.5 times that of conventional LNG carriers.[6][7]
