This report deals with dynamic stability problems of ro/ro ships, covering three aspects: analysis of capsize incidents of some ro/ro ships, development of analysis tools and studies of some dynamic stability problems of ro/ro ships. Three capsize incidents of the ro/ro ships HERALD OF FREE ENTERPRISE, VINKA GORTHON and ZENOBIA have been analyzed by means of theories of ship dynamics in calm water and in waves. Development of analysis methods progressed continuously during the period 1986-1994 in connection with the author's research activity in analysing practical dynamic problems and resulted in SMS - a platform in terms of computer code for ship dynamic analysis in time-domain. Some research work has been carried out in order to investigate parametrically excited roll motion and the simultaneous effect of wave-induced ship motions on cargo shifting. A derivation has been made so that the GM-variation of a ship in waves can be represented as a Volterra system. Thereby the explicit relationship between the hull form and its GM-variation in waves can be obtained.
