Akita Port is one of the most important ports on the Sea of Japan side, playing an important role as a logistics hub in Akita Prefecture. In 2023, thirteen landing-type offshore power generators were installed in the port. However, the power generation facilities are located around breakwaters, which are relatively close to container groups and anchored vessels in the port. In this study, a hydraulic model experiment was conducted to investigate the speed and load of drifting debris impacting the offshore wind turbines. As a result, the behavior of the drifting object model was different for the first wave and the second and subsequent waves of the assumed tsunami. The maximum load on the structure model tended to increase as the difference between the storage depth and the inundation depth increased, but this was not the case for the drifting object model.
