Taking Fortran language as the platform, the mathematical model of two-dimensional non-uniform flow based on plane and the mathematical model of ship maneuvering were developed from the bottom layer, and by further coupling the influence of wind, the mathematical model of ship maneuvering motion based on wind and current effects was constructed. Taking a typical river section in the Three Gorges Reservoir Area as an example, the numerical simulation of ship maneuvering motion under calm wind, uniform wind and random wind effect was carried out. The results show that the ships are obviously affected by wind in this river section. With the increasing change frequency of wind speed and direction, the difficulty of ship control increases correspondingly. In order to avoid the marine accident, the ship must steer in time. The result shows that the model can better simulate the ship maneuvering motion and navigation status under wind effect, which can provide some references for the ship’s navigation and maneuvering in inland river.
