<p>A method is described for the dampening of the roll movements of a ship at sea, said ship comprises one or more, in the main, transversely placed, partially filled with liquid, roll dampening tanks, where the liquid in the tank is set up to swing in antiphase with the roll movements of the ship to hinder that the ship rolls, where a measuring and a control system is used to register antiphase and possible deviations from said antiphase and the amount of liquid in the tank is regulated to achieve said antiphase. The method is characterised in that the height of the liquid up along the wall surfaces of the tank, in particular along the end wall surfaces, is measured and registered at any time with the help of one or more sensor elements, said height measurement data from the one or more sensor elements is registered in a monitoring system that determines said deviation from the ideal antiphase, and on the basis of said measurement data the system carries out a regulation of the amount of fluid in the tank to achieve said antiphase. Also described is a device for carrying out the method.</p> |
