Due to the existence of the side wall of the towing tank, the measured hydrodynamic forces would present some discrepancies compared to the open sea results. This phenomenon is referred as side wall effect. The object of the present study is to investigate the parameters which determine the side wall effects. The method used in the present study involves a 3D panel method based on Rankine type Green function. A ship advancing in a towing tank with parallel side walls is simulated and the numerical results are validated against model test results carried out by Kashiwagi and Ohkusu (1991). The parameters including wave frequency and forward speed which determine the side wall effects are discussed.
