滚装船在拖轮辅助下丁靠斜坡道的船舶系泊试验研究OACSTPCD

The paper examined a dock project by conducting physical model tests on the mooring of a 10 000-tonne roll-on/roll-off ship using tugboat assistance on a sloping ramp.The cable tension and ship motion were explored under various combinations of wind,waves,and currents,providing relevant operational and mooring conditions for design and operational purposes.The findings indicate that the cable arrangement was reasonably effective in the design scheme.The forces of wind,waves,and currents on the roll-on/roll-off ship were effectively balanced through the use of tugboat assistance.The tension of each cable group remained below 50%of the breaking force,following the design standard.Regarding the mooring system's characteristic values,the factors that influenced it in order of significance were waves,wind,and water flow,with the wave period being the most impactful factor.Under identical wave conditions,waves with a SW orientation had a greater negative impact than those with a WSW orientation.Therefore,in actual operation and management,it is crucial to adjust the mooring and operational status according to the numerical simulation results of the waves and the actual wave direction in front of the dock.
