AB - The wave overtopping system in wave power generation systems is called the Overtopping Wave Energy Converter (OWEC). The performance of the OWEC is affected by wave height and period. Wave characteristics, such as wave height, period, and direction, vary with environmental conditions, which make it difficult for the OWEC to generate stable electric power. To mitigate this issue, appropriate OWEC designs based on environmental conditions and wave characteristics must be investigated. In this study, the hydraulic efficiency of the OWEC and the load acting on it were calculated using the Smoothed Particle Hydrodynamics (SPH) based on the environmental conditions along the Ulleungdo coast, and the structural safety of the optimized OWEC model was verified. Moreover, a particle-based simulation was performed to confirm the effect of design parameters on energy efficiency. Additionally, the load acting on the OWEC was calculated, and the optimization method was used to design six types of substructures. Finally, structural analysis was conducted, confirming that all six types avoided the design model's structural resonance period.
