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
【課題】簡略な方法で船体の一部を液化ガスタンクとして構成する。【解決手段】液化ガスタンク10の外殻を内殻14、上甲板16、バルクヘッド18で構成する。タンク外殻の内側表面と、タンク外殻から内側に突出する骨材24の周囲を第1断熱層26で覆い、第1断熱層26の内側表面を第1ポリウレア層28で液密に覆う。更に、第1ポリウレア層28の内側表面を第2断熱層30で覆うとともに、第2断熱層30の内側表面を第2ポリウレア層32で液密に覆う。【選択図】図1
