The features of neuroevolutional modelling of emergency ship dynamics on waves is discussed. An application of neuroevolu-tionary methods and catastrophe theory models for interpretation of emergency ship behaviour on waves is considered. Deci-sion-making methods for analysis and forecast of extreme situations on the basis of catastrophe theory receive much attention. Intellectual system «Unsinkability» is a real-time system based on competition principle. Its concept allows continuous monitor-ing of emergency ship dynamics on irregular waves. The system evolution is determined by the environment and is realized through self organization and adaptation to external disturbances. The practical realization of catastrophe theory models is dis-cussed with reference to tasks of unsinkability dynamics in the context of soft computing. The shape of an interaction area is de-termined by the interaction of restoring and disturbing components during the system evolution in complex dynamic environ-ment. A pattern of changing of this area is described in the space of dynamic catastrophe model in modelling of emergency ship behaviour. Fixed phases of this behaviour are realized in the context of quasi stationarity hypothesis and are specified on the ba-sis of fractal geometry.
