Abstract:

About 25 years ago, the author developed a method for predicting the roll damping of a ship, and the method is widely used even now. The method is a component-based one, and each component is predicted by theoretical ways if possible, otherwise by empirical ways. For these 25 years, the methods have been modified to improve accuracy and to extend their applicability to other kinds of ships. In this paper the author reviews these continuing studies on the roll damping prediction of ships, and introduces the application to determine optimum size and location of bilge keels.
