This paper presents preliminary design results of a mooring buoy and arrayed Wave Energy converter (WEC) platform producing a total rated power of 1.0 MW. The single point mooring buoy system is configured to moor the WEC platform and buoy itself for the various environmental conditions of design operating, extreme and survival. The system considers permanent connection of the platform to the buoy with hawsers during the service life. The buoy will have a weathervaning capability to allow the WEC platform to rotate 360 degrees around the buoy toward the incident wave directions, which enables consistent power generation. The power produced in the platform is transferred to shore with a cable through the buoy. The platform with V-shape configuration consists of two long slender leg structures with 120 degree opening leg angle. Each leg structure is a truss-shape structure with pontoons, braces, rotors, generators, hydraulic pipes and other appurtenances. Fully coupled simulations of the buoy and WEC platform were carried out for the design load cases to evaluate the dynamic responses of the buoy and platform. The results were validated with the ABS design requirements.
