Title:
ANTI-ROLLING APPARATUS FOR SHIPS, SHIP, ANTI-ROLLING METHOD FOR SHIPS
Document Type and Number:
WIPO Patent Application WO/2021/251415
Kind Code:
A1
Abstract:
Provided are an anti-rolling apparatus for ships, a ship, and an anti-rolling method for ships which enable efficient imparting of an anti-rolling effect with a simple structure even in the case where the center of gravity of a ship body varies depending on a load state. An anti-rolling apparatus 3 is provided with a water pouring means 32 for supplying seawater in an ART 31, a water draining means 33 for draining seawater from the ART 31, and a control device 4 for controlling switching between the water pouring means 32 and the water draining means 33. The control device 4 calculates, from the GM (metacenter height) of a ship 1 calculated by a loading computer, a sway-specific cycle in a loaded state thereof, and then calculates a rolling reduction rate of the anti-rolling apparatus 3 in each wave cycle, to thereby determine whether to supply seawater to the the ART 31, or to drain seawater from the ART 31.
