Abstract

In the complex marine environment, there are some nonlinear phenomena such as the wave impinge on the front of the oscillationg buoy wave energy device, the wave run-up and overtopping during the interaction between the wave and the oscillating buoy, with negative effects on the safety and the working performance of the wave energy device. In this paper, the physical model tests are designed and conducted to investigate the wave run-up characteristics of the buoy on the wave-facing side, and the effects of the wave period, the value of constant PTO damping and the buoy motion amplitude on the wave run-up are discussed. Studies show that when the wave period is large and the PTO damping is small, it is beneficial to reduce the wave run-up amplitude on the wave-facing side of the buoy. When the wave period is small, the variation of the PTO damping has a very small effect on the wave run-up amplitude, while the run-up values are significantly affected by the amplitude of the heave motion.
