Designing the whole WEC system requires an effective design approach that considers mutual couplings among them throughout the entire design process. Moreover, the traditional serial design approach, transitioning from small-scale to full-scale designs incrementally, often overlooks issues related to scaling factors. This can lead to unexpected challenges and delays towards real ocean deployment. To address system-level considerations and scaling challenges in WEC design, this study introduces a novel multi-scale concurrent design approach. It facilitates full-scale WEC design from the early concept to ocean test planning. This approach ensures a holistic and effective design process that considers interactions among subsystems at each design stage and incorporates control co-design starting with early concept development. To demonstrate the presented approach, we introduce a case study focused on the design of a 100 kW floating oscillating surge wave energy converter (FOSWEC) for PacWave South ocean test site. This includes the design of wave capture structure and station keeping, PTO, control, ocean test planning, and techno-economic analysis.
