Cover Story: The growing interest in offshore and maritime activities, driven by larger ships and the expanding offshore wind and marine renewable energy sector, highlights the importance of floating breakwaters for creating sheltered offshore areas, ideal for hosting multipurpose energy hubs. Integrating wave energy conversion features into breakwaters meets this demand, enabling efficient use of marine resources. This study investigates how the spacing parameter affects the effectiveness of an array of innovative hybrid modules, serving as both floating breakwaters and wave energy converters. These modules adjust draft automatically for dual functionality. Wave tank tests assessed hydraulic performance by analyzing transmission, reflection, and dissipation coefficients. The results underscore the critical role of spacing in optimizing performance and effectively integrating wave energy extraction. View this paper
