This study investigates the vital role of floating breakwaters in mitigating wave energy in intermediate water environments, crucial for shoreline protection and ecosystem preservation. Various floating breakwater types are analyzed for their effectiveness in attenuating the wave force. Through numerical simulations of computational fluid dynamics in ANSYS Fluent, different breakwater cross sections are evaluated in time-series domain for wave approaching at varying wave periods. The comparative analysis encompasses a range of breakwater designs, including box-type, stepped-box type, pontoon-type, box-with-plates type, dual-box type and T-shaped breakwater. The transmission of waves when passing through these breakwaters are studied to assess breakwater efficiency in mitigating the wave forces. The incident and transmitted wave elevations in each breakwater type observed at a selected time among the upstream and downstream locations are tracked and compared. The most efficient breakwater type for wave attenuation is then chosen to demonstrate its impact over time. The study aims to inform decision-makers and coastal engineers on selecting optimal floating breakwater solutions suitable for tropical climate. This research enhances our understanding of wave attenuation, aiding coastal protection and sustainable development while also exploring its impacts on ecosystem dynamics.
