The turbine is mounted on a buoyant underwater structure anchored in deep water. The wind turbine, tower and underwater structure are permanently joined and rotate as a single unit with water carrying the full weight of the structure which, similar to a sailing boat, is stabilized by the keel.
The unit does not require a yaw system for the turbine to face the wind nor a pitching mechanism to turn the rotor blades. Accordingly, fewer moving parts incur lower maintenance and operating costs. The SeaTwirl S2, 1MW turbine is expected to be available in 2020.
