【Abstract】 Some mathematical models, which are about ship’s stability monitoring are discussed and built by applying the stochastic stability theory. By real time analyzing and self adapting value analyzing, hydrodynamic coefficient for ship’s rolling is dealt with.The dynamic stability norms are put forth, and therefore the real time calculation and prediction for ships in wave and wind have been made.By calculated examples,it is proved that by dynamic stability prediction method applied to ships in stochastic wind and wave,a ship’s stability reserves and safety performances can be estimated effectively更多还原
