Abstract: 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 corner 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.

Abstract: A horizontal type cylindrical double-shell tank includes an inner shell and an outer shell. The inner shell includes an inner shell main part storing a liquefied gas and an inner shell dome protruding from the inner shell main part. The outer shell forms a vacuum space between the inner shell and the outer shell, and includes an outer shell main part surrounding the inner shell main part and an outer shell dome surrounding the inner shell dome. The inner shell dome is provided with an inner shell manhole. The outer shell dome is provided with an outer shell manhole at a position corresponding to a position of the inner shell manhole.

Abstract: A structure of a horizontal type cylindrical double-shell tank mounted on a ship includes: an inner shell storing liquefied gas; and an outer shell forming a vacuum space between the inner shell and the outer shell. A pair of support units supporting the inner shell is disposed between the inner shell and the outer shell. Each support unit includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank; a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the inner shell side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at the outer shell side. Each of the cylindrical elements is made of glass fiber reinforced plastic.

Abstract: A support structure of a ship tank includes: a curved surface facing an outer peripheral surface of a horizontal type cylindrical tank; and a pair of support units supporting the tank on the curved surface. Each of the support units includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank; a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the tank side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at an opposite side to the tank. The inner members are fixed to the tank. The outer members of one of the support units are configured such that displacement of the outer members in an axial direction of the tank relative to the curved surface is restricted.
