Abstract

Based on the practical needs of offshore photovoltaic systems, various floating wave-dissipation structures were designed and tested in a two-dimensional large-scale wave tank under irregular wave conditions. Time-domain response signals were measured, and the wave transmission coefficient, reflection coefficient, and wave energy dissipation coefficient were analyzed. The study demonstrates that compared to single-floating-box breakwater, increasing the width of a single floating box, adding additional floating boxes, and incorporating vertical insert plates or wing plates on the bottom can significantly enhance wave energy dissipation and improve wave attenuation. For the designed double-floating-boxes structure, each 0.5 m increase in the slanted wing depth reduces the transmission coefficient by an average of 15%. Additionally, installing a porous plate between the pontoons further reduces the transmission coefficient. Under irregular waves with an effective wave height of 2 m, the wave energy transmitted through the dual-pontoon floating breakwater with wing plates and porous insert plates is only 12% left, meeting the wave attenuation requirements for offshore floating photovoltaic power stations.
