In our previous study, we proposed the numerical simulation procedure of moored ship motions induced by tsunami, and investigated the effects on ship motions and mooring loads, considering berth location, ship's dimension and mooring system. In some cases, large ship movements beyond the safe mooring conditions were induced by the surface elevation, the currents and a resonance effect with natural periods of sway or surge of the moored ships. In the proposed method, the calculated horizontal currents were not able to be reproduced well, compared with those by the tsunami simulation directly. In this paper, we investigate the difference of the currents, and improve the accuracy of the connection between the tsunami simulation and the simulation of the moored ship motions.
