碩士 / 國立臺灣大學 / 工程科學及海洋工程學研究所 / 96 / In the present study, a numerical model is developed for simulating the dynamic responses of a mooring ship system under the action of waves and winds. In the mooring system, a mooring ship, elastic catenary mooring lines and elastic fenders are considered. A linear strip method is applied to formulate the 6-DOF ship motions, but the interacting nonlinear forces of the mooring lines and fenders make the equations of motion nonlinear and have to be solved in time domain step by step. A series of numerical simulation has been conducted for investigating the nonlinear responses dependence on wave length, wave height, wave direction, wind speed and wind direction. Through the simulation, the time histories of ship motion, tension forces of mooring lines, and reacting forces of fender are obtained, and the characteristics of the nonlinear responses of a mooring ship system are discussed.
