案登録請求の範囲第１項に記載の半潜水装置。[Claims for Utility Model Registration] (1) Two or more elongated floats;
at least one working or living deck disposed above the float, and at least three pedestals extending from the deck to the float;
A semi-submersible device that automatically reduces or limits inclination caused by leakage, wherein a buoyant body having a constant buoyancy is provided on the outside of the pedestal on the float, the buoyant body is having a center of volume located above the center of volume of the float associated therewith, when said semi-submersible device is in a normal semi-submersible state, said buoyant body is completely submerged below the water surface and said semi-submersible device is When tilted, at least one buoyant body projects above the water surface, thereby displacing the center of buoyancy of the entire semi-submersible device, reducing and limiting the tilt angle of the semi-submersible device to a maximum angle of 15°. A semi-submersible device, wherein the buoyant body is provided at both ends of the float. (2) The center of volume at both ends of each float, including the buoyant body, is at least 3 times deeper than the center of volume of the entire float below the water surface.
The semi-submersible device according to claim 1, wherein the semi-submersible device is located upward by 0%.
