PROBLEM TO BE SOLVED: To shorten the construction period of an LNG carrier by assembling an LNG tank on the ground and mounting it in a hold of the carrier.SOLUTION: An LNG tank 5 is formed by placing a cold insulator 7 and a membrane 8 inside a skeleton container 6, and loaded in a hold 2 of a double hull structure. A girder material 9 is welded onto an outer surface of the skeleton container to ensure sufficient reinforcement before a cold insulation work so that the skeleton container is not deformed upon loading. When the tank is loaded in the hold, the girder material of the skeleton container is connected to a hull inner shell 1 to integrate the LNG tank with the hull, and to thereby support the liquid cargo load jointly by the skeleton container and the hull. |
