In the former report we obtained the so called equivalent linearized roll damping coefficients by the experiment of forced irregular roll with large amplitude. In this report, we applied the obtained coefficient for predicting ship roll time history in high irregular waves using various method and compared with the results obtained from experiments performed in the towing tank.
And after that it is shown that the calculation of roll time history by the equivalent linearized method (E. T. method) will be preferable for predicting the order statistic of roll amplitude especially maximum roll angle.
