A 3D viscous numerical wave tank (NWT) was established based on computational fluid dynamics simulation method, and oblique irregular waves were generated by defining inflow boundary conditions. The motions of free surface ship in oblique waves were predicted by solving the Reynolds Averaged NavierStokes (RANS) equations describing the flow around ship. The kinematics equations of rigid body were solved according to the calculation results (forces and moments) in each time step. The heave, roll and pitch transfer functions for container ship model S175 in oblique waves were obtained. The comparisons between simulation results and linear strip theoretical results were carried out, showing good agreement, which demonstrate the present research can provide an effective way to predict seakeeping characteristics.
