Wave to the dynamic response of the ballast floating breakwater

Despite the severe nonlinearity and randomness of liquid sloshing, it can effectively reduce the rocking effect with rational application. As a result, the dynamic response of ballast breakwater in waves, inspired by the antirolling tank, is studied in this paper. To validate the numerical method used in this study, experiments are conducted in the wave flume as part of the current investigation, and good agreements are obtained from the results. Different filling rates for the ballast breakwaters are considered. The wavelet transform is used to examine the pitch and heave amplitude of the breakwater in waves. The power spectral density (PSD) is computed to determine the resonance frequency of the breakwater. Comparisons have also been made between the response amplitude operators (RAOs) to examine how filling rates affect dynamic response. Additionally, the impact of the liquid sloshing inside the breakwater has been studied using pressure points, and the free surface displacement has been observed using wave gauges. It is discovered that the breakwater reacts aggressively at a frequency near both its natural frequency and the incident wave frequency. The pitch motion is more easily influenced than the heave motion, and the filling rate affects the reaction.
