Abstract (en)

A method for reducing wave-induced motion of a ship in that water is conveyed into stabiliser tanks (20) in the hull of a ship (10) from outside the ship and that that the water level in the stabiliser tanks is allowed to settle freely or the water level in the stabiliser tanks is controlled by means of air valves (22). The stabiliser tanks may be equipped with hatches (23) located at the ship's waterline, the hatches being openable in the lateral direction. To reduce the roll motion even further, the ship's hull may also have underwater bilge protrusions (25).
