“…The growing interest in offshore and maritime activities in recent years, driven by the rapidly increasing size of ships and the expansion of the offshore wind and marine renewable energy sector, has emphasized the importance of floating breakwaters. These structures are used to temporarily attenuate waves or even permanently reduce wave loads [1]. Furthermore, as various concepts for offshore areas aimed at exploiting marine natural resources and colocating maritime activities such as aquaculture [2] and offshore wind farms [3,4] are emerging [5], there is a rising interest in incorporating wave energy extraction features into traditional dissipating floating breakwaters.…”

This study examines the impact of the spacing parameter on the efficacy of an array of hybrid modules functioning as both floating breakwaters and wave energy converters. The dual functionality is ensured by the ability of the device to autoadjust its submergence. The behavior of multiple 1:40 scaled modules was tested in the wave tank of the University of Campania “Luigi Vanvitelli”. The objective was to assess the hydraulic performance of the array by analyzing transmission, reflection, and dissipation coefficients under different wave conditions. Specifically, the transmission coefficient ranges between 0.85 and 0.51, depending on the relative wavelength and wave steepness, while the reflection and dissipation coefficients vary, respectively, between 0.70–0.20 and 0.55–0.3. In any case, the results underscore the critical importance of the spacing parameter.

“…Coastal zones around the world face significant challenges due to their increasing use for various purposes, including harbors, fisheries, recreational facilities, and resource extraction [1,2]. However, the utilization of these areas is hindered by natural factors such as high wave action, storm surges, tsunamis, and coastal erosion [1].…”

This experimental study investigated the hydrodynamic performance of the first free-surface semicircular breakwater supported on piles under regular waves. The research focused on SCB models with porosity levels of 0%, 9%, 18%, and 27%. Experimental tests were conducted in a wave flume to evaluate the transmission (CT), reflection (CR), and energy dissipation (CL) coefficients of the SCB models. Wave disturbance coefficients (CF) in front of the breakwater and within the breakwater chamber (CC) were also examined. Horizontal wave loading was measured using normalized force coefficients (Fn), including force coefficients of wave crests (Fn,c) and wave troughs (Fn,t). Empirical formulas were proposed to provide a quick estimate of the hydrodynamic performance, showing good agreement with the measured data. The findings highlight the impact of varying porosity levels on wave attenuation, with the impermeable SCB model (0% porosity) exhibiting superior performance compared to the perforated SCB models. This research contributes valuable insights into optimizing SCB model design and enables efficient estimation of its hydrodynamic performance under regular wave conditions. The results provide valuable guidance for the design and implementation of SCB structures, enhancing their effectiveness in wave attenuation applications.
