In order to improve the probability of rescuing the crew members who have fallen into the water after the abandonment accident at sea, this paper proposes a way to set up multiple fixed interval marine emergency rescue stations to improve the success rate of self rescue and shore based rescue after the crew members have fallen into the water when the abandonment accident at sea occurs. On the basis of establishing the research index system for planning and evaluating the setting of marine emergency rescue stations, entropy weight method, cloud model theory and matter-element extension theory are used to evaluate the rescue effect of sailors who have set up several marine emergency rescue stations on the centerline of the customary route. Taking the setting of several fixed marine emergency rescue stations on the route centerline of the open waters from Chengshanjiao to Changshan Waterway as an example, the safety level of self rescue and rescue of crew members in the waters with different spacing marine emergency rescue stations is evaluated. The results show that the setting of marine emergency rescue stations with an interval of about 4 nautical miles can effectively improve the rescue success rate on the basis of saving investment, This method can provide reference for the design of emergency rescue stations in other coastal waters in the future.
