<p>PROBLEM TO BE SOLVED: To provide a ship turn-over preventing mechanism for preventing the turn-over at a navigation time without using a water ballast, in the case where a ship is caused to drop the water line and raises the center of gravity by a cargo drop, but does not use the water ballast so that the ecosystem of the area where the water ballast is discharged is not broken by the dispersion of a marine organism or a pathogen contained in the water ballast, and so that the position of the vessel can be held in a stable state by a simple mechanism.SOLUTION: A ship 50 comprises: buoyancy generation chambers 2 arranged in the insides of two individual board sides of a ship 50; an intake/exhaust port for causing the individual buoyancy generation chambers 2 to communicate with the outside; a floating body 1 arranged for vertical movements in each of the buoyancy generation chambers; and lock means Lc for fixing said floating body at an arbitrary position and for releasing the fixture.</p> |
