There are many factors affecting the responses of moored ships,and they are very complex.In this paper,the main factors including waves and mooring methods are studied.By physical model tests on a moored ship,the influence of wave conditions and mooring methods on the responses of moored ships is studied.The wave conditions include different wave directions and wave periods,and the mooring methods include different mooring line configurations with or without tail ropes and different mooring arrangement schemes.The research results indicate that the motions and mooring forces of moored ships under the action of 45° oblique waves are significantly smaller than those under the action of transverse waves.Within the experimental wave period range (T=3.5~6.0 s),the motions and mooring forces of the moored ship increase with the increase of the wave period.From the perspective of ship mooring safety,setting up tail ropes is advantageous.The arrangement of mooring lines moored at both the front and rear edges of the dock can significantly improve the resistance of ship mooring to the wind,wave and current,which is for the mooring condition without loading and unloading operations.
