To constitute a part of a vessel body as a liquefied gas tank by a simple method.SOLUTION: An outer shell of a liquefied gas tank 10 is constituted by an inner shell 14, an upper deck 16, and a bulk head 18. An inner surface of the tank outer shell and the periphery of a frame member 24 inwardly projecting from the tank outer shell are covered with a first heat insulation layer 26, and an inner surface of the first heat insulation layer 26 is liquid-tightly covered with a first polyurea layer 28. An inner surface of the first polyurea layer 28 is covered with a second heat insulation layer 30, and an inner surface of the second heat insulation layer 30 is liquid-tightly covered with a second polyurea layer 32.SELECTED DRAWING: Figure 1
