In this paper, numerical simulation and comparative verification tests of two ship models in heading regular waves, which was recommended by ITTC, were conducted. Based on the Reynolds time averaged method for solving the N-S equation, a calculation method of wave interference and 6DOF motions for two ships under horizontal mooring constraints was established. With the model and mooring parameters in the test taken as inputs, the numerical simulation of wave interference between the two ships under typical wave conditions was carried out. The time curves of 6DOF motions, wave surface rise between the two ships and mooring tension were obtained and compared with the results of model tests. The comparison shows that the motions of surge, heave, roll and pitch as well as the wave surface rise of the comparative conditions (wave period: 1.5 s) are in good agreement with the test results. There are relatively large errors in motions of sway and yaw compared with the test results, because these motions result from the coupling of wave system interference between two ships and mooring constraints, and the superposition of multi-factor simulation errors reduces calculation accuracy.
