| Abstract: | A numerical simulation method based on ITTC recommendation was used to investigate the occurrence and magnitude of parametric rolling in longitudinal regular waves.The approach for empirical calculation of roll damping and fast simulation of nonlinear GM variation was presented.The comparison of the numerical results of the parametric rolling prediction for a Ro-Ro ship with the model test results validated the employed method. |
