선체(주변 구조체)에 대해 설치되는 액화가스 탱크는, 선체에 대해 설치되는 액화가스 탱크로서, 액화가스를 저장 가능한 탱크 본체로서, 복수의 면부를 가짐과 동시에 상기 면부들 사이에 상기 면부에 비해 강성이 낮은 모서리부를 구비하는 탱크 본체, 상기 탱크 본체의 하방에서 상기 탱크 본체를 지지하는 저부 서포트체 및 상기 탱크 본체의 측방에서 상기 탱크 본체를 지지하는 복수의 측부 서포트체를 포함하고, 상기 탱크 본체는 상기 탱크 본체에 화물이 비워져 있는 경우에 상기 저부 서포트체에 의해 지지되어 자립하고, 상기 탱크 본체에 액화가스가 저장되어 있는 경우에 상기 저부 서포트체 및 상기 측부 서포트체에 의해 지지되도록 구성된다. A liquefied gas tank installed in a surrounding structural body includes: a tank main body in which a liquefied gas is storable, the tank main body including a plurality of planar portions and corner portions between the planar portions, the comer portions having less rigidity than that of the planar portions; a bottom supporting body that supports the tank main body from below the tank main body; and a plurality of side supporting bodies that support the tank main body from side of the tank main body. The tank main body is configured to stand by itself by being supported by the bottom supporting body when the tank main body stores no cargo, and be supported by the bottom supporting body and the side supporting bodies when the liquefied gas is stored in the tank main body.
