DETERMINATION OF THE CAPABILITY OF ROLL DAMPING DEVICES USING CAPSIZING PROBABILITY

This paper presents a design method for bilge keels of conventional ships by using capsizing probability. First, a calculation method for capsizing probability is well validated with capsizing model experiments of conventional cargo ships. Secondly, it is confirmed by an equivalent linearized method that effects of nonlinear restoring moment are not so significant on capsizing probability. Then, effect of bilge keels on capsizing probability are discussed as well as that of metacentric height. The results demonstrate that bilge keels of cargo ships can be rationally designed by the calculation method for capsizing probability with prediction methods for roll damping coefficient and wave exciting moment.
