Abstract

In our previous study, a numerical simulation procedure on moored ship motions induced by tsunami was proposed, and characteristics of the motions and the mooring loads affected by berth location, ship kind, ship condition and mooring system especially in fender types were investigated. During our investigation, it has been appeared that currents around the ship which is moored near to harbor entrances and/or edges of inside harbor vary drawing a vortex. In this case, excess current forces in not only sway and surge but also in yaw may act the ship. In this paper, we propose a calculation method on current forces of ship under the uneven tsunami currents in direction of ship's bow and stern, and investigate the effect using the simulation procedure.
