A structure of a horizontal type cylindrical double-shell tank (8) mounted on a ship includes: an inner shell (2) storing a liquefied gas; and an outer shell (3) forming a vacuum space between the inner shell (2) and the outer shell (3). A pair of support units (4A, 4B) supporting the inner shell (2) is disposed between the inner shell (2) and the outer shell (3). Each support unit includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank (8) such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank (8); a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the inner shell (2) side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at the outer shell (3) side. Each of the cylindrical elements is made of glass fiber reinforced plastic. |
