A typical LNG carrier has four to six tanks located along the center-line of the vessel. Surrounding the tanks is a combination of ballast tanks, cofferdams and voids; in effect, this gives the vessel a double-hull type design. LNG carriers, like aircraft carriers, are among the most difficult vessels to build, taking as long as 30 months. [24]

As the cargo tanks absorbed heat from the sea, a portion of the cryogenic LNG cargo boils off, changing from a liquid to a vapor (gas). As a result, pressure within the cargo tanks increases; similar to boiling water in a pressure cooker. To prevent rupturing the thin Invar tank material, pressure is controlled by venting the natural gas ...
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 m 3 and 216,000 m 3. [5]
These relate to window fire-rating requirements on gas carriers. [9] A revised model form of certification (known as the Certificate of Fitness), adopted in May 2018 and entered into force on 1 January 2020. [8] Amendments to include new requirements on watertight doors on gas carriers, due to enter into force on 1 July 2024. [10]
The pier would have at least two insulated lines, one for loading and/or unloading LNG and one for vapor supply or recovery as the vapor space above the LNG changes as the cargo is transferred. Ship-based or shore-based cryogenic pumps [10] are used to transfer the LNG to/from the LNG storage tanks on shore.
