Abstract

A two dimensional nonlinear time domain strip theory for the seakeeping analysis of ship behaviour under large amplitude waves is presented. Here the fluid actions are evaluated at each time step using the actual wetted hull portion and the exciting wave elevation as free surface. The radiation problem is partially solved in time domain with the employment of a convolution integral in the history of motion. The nonlinear system of equations of motion is numerically solved in time domain via a fourth order Runge-Kutta method. The proposed nonlinear method is applied to the S-175 Container ship and the results are compared with the predictions for small amplitude waves obtained from the results published by other researchers. A study of the behaviour of the vessel under large amplitude waves is presented.
