PURPOSE:To enhance the efficiency of volume, by mounting a cylindrical tank having a heat-insulation on the outer peripheral surface thereof and its ceiling which has an upward convex curve surface, onto a hull structure through the intermediary of a tank bottom heat-insulating support structure so that the support of the tank may be made simple. CONSTITUTION:Cylindrical tanks 11a-11d each having a heat-insulation on its outer peripheral surface and its ceiling which has an upward convex curve surface are mounted on a hull structure through the intermediary of a tank bottom heat-insulating support structure. It is possible to a large tank volume may be ensured in comparison with the size of the ship so that the efficiency of volume may be made large. Further, the tank support structure may be made simple.
