The growing demand for resilient and environmentally adaptive coastal protection solutions has spurred research into innovative floating breakwater (FB) designs. This study introduces and evaluates the hydrodynamic performance of a newly developed H-type porous floating breakwater (TFB-3), which incorporates perforated vertical plates to enhance energy dissipation. Using a series of physical model experiments, the TFB-3’s performance is compared with two established FB designs: the conventional rectangular TFB-1 and the modified semicircular TFB-2. Experimental results demonstate that TFB-3 significantly outperforms both reference models in attenuating wave energy. Specifically, TFB-3 exhibits lower wave transmission and reflection coefficients, greater energy dissipation, and reduced wave disturbance in front of the structure. These improvements are particularly relevant for deployment in soft-soil coastal regions, where traditional breakwaters are often impratical. The findings highlight the potential of TFB-3 as a robust and scalable solution for coastal protection under a range of wave conditions. This work contributes valuable experimental data and practical insights to inform the design and application of advanced porous FBs.
