PURPOSE:To expose a ship body to its bottom part above the level of water, by arranging plural long and narrow float tank under the ship body in a direction at a right angle with the longitudinal direction of the ship body and discharging water from the float tank under a condition in which a stabilizer cone is extended through the level of water. CONSTITUTION:A float tank structure 1 is such that a stabilizer cone 2 is vertically provided to one end of an upper supporting surface 1a and a host of ballast tank 3 are equipped to the inside. The plural structures 1 are arranged under a ship S floating on the surface of the sea in a direction at a right angle with the longitudinal direction of the ship, and the cone 2 protruded above the surface of the sea is placed so as to be vertically held with respect to the surface of the sea while the surface 1a is horizontally maintained. Then water is discharged from the ballast tank 3, and the surface 1a is softly contacted to a lower surface in the bottom part of the ship S, further the discharge of water is continued, and the ship S is exposed above the surface of the sea to its bottom part. |
