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.

Double-shell tank and liquefied gas carrier ship

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.

Double-shell ship tank structure and liquefied gas carrier

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. The outer members of the other one of the support units are configured to be slidable on the curved surface in the axial direction of the tank.
