Abstract
Based on the coupled equations of ship oscillatory motions including pitch and heave, and where wave forces and moments were calculated by using Ordinary Strip Method(OSM), the amplitude of oscillatory motions of a ship in regular waves was numerically simulated in this paper. The simulation of oscillatory motions was also carried out in the case of changing the scattering intensity and frequency. By comparing oscillatory amplitudes with and without encounter frequency scattering, the following conclusions can be obtained: the encounter frequency scattering can change the oscillatory amplitudes of a ship in regular waves, and the changing values were relative to the scattering intensity and frequency. It can also be obtained from the numerically simulation that the oscillatory amplitudes can be reduced by adopting reasonable scattering mechanism.
