    In the Port of Shibushi in Japan, problems arise due to long-period oscillations of moored ships when there is a typhoon located far offshore. To investigate the detailed processes of these oscillations and develop effective countermeasures, image processing, wave observations and numerical simulations were conducted. The image processing results showed obvious surging motions of large cargo vessels with a period of about 60-70 s. The results of wave observations showed the existence of waves with long periods of 60-70 s. Numerical simulations revealed that such long-period waves were generated when the peak period of incident waves was set to 120 s as observed. These findings show that small-scaled harbor oscillations occur inside the port.
