Navigational safety is an important issue in maritime transportation. The most frequent type of maritime accident in the port and coastal waters is the ship collision. Although some ship collision models have been developed in the past, few have taken account of wind and sea current effects. However, wind and sea current are critical factors in ship maneuvering. Therefore, based on the previous collision model without wind and sea current effects, this study further develops a ship collision model with wind and sea current effects. Finally, a comparison of the results for the proposed collision model in this study and the ship maneuvering simulator is shown to illustrate the effectiveness of the proposed mathematical model in this paper, followed by the conclusions and suggestions given to navigators, port managers, and governmental maritime departments to improve navigational safety in port and coastal waters.

航行安全是海上运输中的重要问题。港口和沿海水域最常见的海上事故是船舶相撞。尽管过去已经开发了一些船舶碰撞模型，但是很少考虑风和海流的影响。但是，风和海流是船舶操纵的关键因素。因此，本研究在以前没有风，海流影响的碰撞模型的基础上，进一步发展了具有风，海流影响的船舶碰撞模型。最后，将本研究中提出的碰撞模型与船舶操纵模拟器的结果进行比较，以说明本文中提出的数学模型的有效性，然后给出了对航海家，港口管理者的结论和建议，
