Renewable energy costs have declined but are still unable to consistently meet power consumption demands when needed most. The Wavewatts concept is able to consistently deliver critical dispatchable renewable energy by directly converting large and slow moving forces of wave energy into compressed air. This investigation looks to confirm the anticipated performance and dynamics of the Wavewatts two body Wave Energy Converter (WEC). This project aimed to build a working and validated WEC-Sim model of the full-scale Wavewatts WEC which can be used to test the WEC in different wave conditions and extract desired results. The specific metrics used to demonstrate the performance of the device are the response amplitude operators, loads on bodies and cables (e.g., forces, moments), response of bodies and cables (e.g., displacement, velocity), and power take-off (PTO) mechanical power production. This submission includes the public Post Access Report (PAR) for WEC-Sim simulation data for the Wavewatts spar buoy WEC and a link to the unredacted project data and PAR. This project is part of the TEAMER RFTS 11 (request for technical support) program.
