Abstract

Most existing studies on wave energy converters （WECs） have failed to account for structural damage induced by wave run-up on the buoy surface. To address this issue, the modeling test is conducted on a segmented annular buoy to quantify the influences of wave period and draft on wave run-up characteristics. The experimental results demonstrate that wave run-up is significantly amplified when the wave period approaches the natural period of the segmented annular buoy. Wave run-up also exhibits a monotonic increase with growing draft, where the magnitude of the increase is strongly dependent on the wave period. Furthermore, analysis of wave field distribution around the buoy under specific conditions demonstrates that the heave motion of the segmented annular buoy predominantly affects the wave field on the wave-ward side, while its effect on the leeward is restricted to a narrow range.
