A time domain code based on the linear model for diffraction and radiation forces combined with a nonlinear model for Froude-Krylov and hydrostatic forces is used to predict the responses of a containership in a predefined sea state with embedded abnormal waves. The responses include both vertical motions and bending moments. These results are compared with experiments conducted in a wave tank with the aforementioned containership for different Froude numbers in the predefined wave sequence known as the “Three Sisters”. The main purpose behind the experiment is to check the behaviour of the ship in extreme sea states. These experiments revealed little but the key influence of green water shipping on the ship responses especially on the sagging moment and is used as a guideline to modify the time domain code in a heuristic manner to incorporate the green water effect. The updated numerical model is again tested and compared with the experiment for further validation.
