Outline of Final Research Achievements

A non-linear time-domain simulation method was developed for predicting maneuvering motions of ships in adverse weather conditions, and validated through the comparison with tank model test results. Obtaining an equilibrium of the ship in adverse weather conditions and linearizing the motion equations of the ship at the equilibrium, a new theoretical method was developed for judgement of course-keeping ability of ships. By means of the developed two calculation tools, the time-domain maneuvering simulation method and the theoretical method for course-keeping ability, the maneuvering motions and oscillations in waves were predicted for various kinds of ships with changing the external disturbance condition and the engine output. Based on the prediction results, the external disturbance conditions where the safe navigation is possible, and the effect of the engine output were presented in detail.
