Abstract Numerical simulations of diffraction problem of WrigleyIII advancing with certain forward speeds were carried out in the numerical wave tank (NWT), which is established based on computational fluid dynamics(CFD) method. Regular waves making and propagation were simulated and verified in a reference coordinate system. Wave forces of the retrained WigleyIII advancing in both heading and oblique waves were computed respectively in NWT. Comparison of the present results, the corresponding ones of potential flow theories and experimental one from Delft University of Technology, was made. It shows they agree well each other. The proposed method is of great significance to further analyze and predict hydrodynamic performance of ship and marine floating structures in waves.
