The conversion of ocean wave energy into electricity offers a sustainable solution to global energy demands. This study investigates the influence of floater geometry on the hydrodynamic performance of a multi-cylinder floating-point-absorber wave energy converter to enhance its site-specific efficiency. Employing a face-centered central composite design and the boundary element method, the performance of various cylindrical, truncated cone, and inverted truncated cone geometries was evaluated. The results demonstrate that floater geometry critically dictates the resonance and power absorption, with surge and heave motions being the dominant contributors. A key finding is the crucial distinction between peak theoretical power and site-specific performance. While one design achieved the highest absolute power output (140.844 W), its resonant period was misaligned with the target sites dominant wave period (2.7 s), leading to poor performance (7.550 W) in those conditions. Conversely, a cylindrical design with a closely aligned resonant period yielded the highest power (134.592 W) at the dominant wave period. This study concludes that matching the WECs resonant characteristics to the local wave climate is paramount for maximizing practical energy capture, superseding the importance of absolute peak power alone.
