A low temperature liquid tank (1) provided with: a storage tank (5) having a bottom (5a) obtained by joining multiple bottom plates (5a1); and a support (10) for supporting the bottom. The support is provided with: an outer support section (11) for supporting the margin of the storage tank including the side walls of the storage tank; and an inner support section (12), which comprises a heat-insulating material (4b1) that creeps as a result of a load being applied and which is disposed on the inside of the outer support section. The initial height of the upper surface of the inner support section is set so that during the service life of the low temperature liquid tank, the maximum bending stress acting on the bottom plates as a result of the difference between the height of the upper surface of the inner support section and the height of the upper surface of the outer support section does not exceed the allowable bending stress for the bottoms plates. |
