In the long-term voyage,the ship will encounter the situation that the ship breaks down and passes through the narrow channel,and the tugboat is required to tug the ship to sail.This paper takes ship towing as the research object,uses the hydrodynamic software AQWA to analyze the influence of different number of towing lines and different towing speeds on the towing of ships in the process of time-domain coupling analysis.The tension and motion response are com-pared and analyzed.The results show that under the same environmental conditions,the maximum tension of two streamers is reduced by an average of 49.18％compared with one streamer,and the maximum tension of two streamers is reduced by an average of 53.78％when the towing speed is 4 kn compared with the towing speed of 8 kn,when the towing speed of 6 kn is lower than that of the towed speed of 8 kn,the maximum tension of the streamer is reduced by 29.39％on average.
