Currently, when predicting the ship maneuvering motion in waves based on the mathematical model of ship maneuvering motion, hydrodynamic coefficients are mostly obtained through the model test or numerical prediction in still water, without considering the influence of waves on ship maneuvering hydrodynamics. Therefore, establishing the prediction method of ship maneuvering motion hydrodynamics in waves is essential for accurately predicting ship maneuvering motion. In this paper, the multi-degree-of-freedom motion of ship in waves was numerically modeled based on the overset grid method. The hydrodynamic modeling, free surface treatment and wave simulation methods were presented. The numerical simulation method of ship maneuvering hydrodynamic forces in waves was established. The hydrodynamic model test and numerical prediction of S175-ship in regular waves were carried out, and the influence of waves on ship hydrodynamics was evaluated. The numerical prediction results were compared with the model test results to verify the reliability and practicability of the numerical simulation method. The research in this paper can provide a guidance for the improvement of the ship maneuvering prediction in waves.
