Marine tank support structure and liquefied gas carrier

摘要

A support structure of a ship tank includes: a curved surface facing an outer peripheral surface of a horizontal type cylindrical tank (2); and a pair of support units (4A, 4B) supporting the tank 2 on the curved surface. Each of the support units includes: a plurality of cylindrical elements (5) arranged in a circumferential direction of the tank (2) such that an axial direction of each of the cylindrical elements (5) coincides with a radial direction of the tank (2); a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements (5) at the tank (2) side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements (5) at an opposite side to the tank (2). The inner members are fixed to the tank (2). The outer members of one of the support units (4A) are configured such that displacement of the outer members in an axial direction of the tank (2) relative to the curved surface is restricted. The outer members of the other one of the support units (4B) are configured to be slidable on the curved surface in the axial direction of the tank (2).
