| Research Abstract |
In this study, the estimation procedure on parameters of ship motions such as the damping coefficient, the natural frequency and so on in parametric rolling based on time series analysis is constructed. Moreover, by using the estimated parameter of ship motions, the safety judgment index is proposed. The effectiveness of this is confirmed by using the time series of model experiments. Onboard experiments are also carried out. However, we were not able to observe the parametric rolling phenomenon.
