Abstract:This paper studies the mooring force and movement of 275HP bow-stern double mooring trawler under the action of wind and wave,wave and current or wind and wave and current.The experimental results show that the mooring force and rolling angle under the action of wind and wave are both higher than that under the action of wave.When current velocity is less than 1.0 m/s,the mooring force under the action of wave and current is greater than that under the action of wave,while the rolling angle is slightly less.Bow-stern tension force under the combined action of wind,wave and current is greater than that with the effect of wind and wave or wave and current.Because of the difference of bow-stern area of fishing boat affected by wind and current,the influence of current on bow tension force is greater and the influence of wind on stern is greater.Considering the inhibitory effect of the initial rolling angle of fishing boat on its motion,the rolling angle under the combined action of wind,wave and current is slightly lower than the value under the action of wind and wave.According to the experiment,the allowable wave height of 0.6 m is suggested when there are about force 10 wind and current with the velocity less than 1 m/s at the same time in the port.
