Natural gas liquefaction vessel

A natural gas liquefaction vessel comprising:

• the natural gas liquefaction vessel newbuilt on a Q-Max class hull, the Q-Max class hull comprising a cargo hold;
• a plurality of membrane-type cryogenic cargo tanks installed within the cargo hold, the plurality of cryogenic cargo tanks each about 41 m wide;
• at least one pair of ballast wing tanks, one each on a port side and a starboard side of the cargo hold and adjacent to at least one cryogenic cargo tank of the plurality of cryogenic cargo tanks, each ballast wing tanks about 7 m wide;
• a trunk deck above the cargo hold, the trunk deck extending over the plurality of cryogenic cargo tanks and over the at least one pair of ballast wing tanks;
• and
• a natural gas liquefaction plant on the trunk deck;
• the natural gas liquefaction plant comprising a gas loading and reception manifold at a bow of the natural gas liquefaction vessel fluidly coupled to a source of natural gas;
• an amine module, the amine module comprising at least one compressor and acid gas removal pre-treatment equipment;
• the amine module fluidly coupled to a dehydration module and mercury removal equipment;
• the dehydration module and mercury removal equipment fluidly coupled to a liquefaction module;
• the liquefaction module and a Boil Off Gas (BOG) module both fluidly coupled to both the plurality of cryogenic cargo tanks;
• and
• wherein the about 41 m wide cryogenic cargo tanks and about 7 m wide ballast wing tanks form a saved deadweight;
• and
• wherein the saved deadweight is applied to the trunk deck and the natural gas liquefaction plant.
