The patent "Wind-Wave Energy Hybrid Generator" (Patent No. 201220479451) discloses a wind-wave energy hybrid generator, which comprehensively utilizes two unstable new energy sources on the ocean, outputs electric energy, and improves resource utilization; but this device is only applicable to sea areas. limited to shallow water

In 2012, Professor Muliawan of the United States combined the power generation principles of the Spar-type floating wind turbine Hywind and the oscillating float wave energy generation device Wavebob to propose an STC hybrid utilization system; but the damping in the heaving direction is small, and the wave energy float increases the range of motion in the heaving direction , which brings unfavorable factors to wind turbine power generation, and is only suitable for deep water areas

The European "MARINA Platform" project proposed the C-HyP concept in 2013. This hybrid utilization system uses a circular barge with a diameter of 100 meters as a supporting platform to provide buoyancy for the 5MW wind turbine installed on it. Install 20 independent surge wave energy absorbing devices in the semicircle area; however, the system will be subjected to relatively large wave force, which requires high positioning system and is not suitable for use in harsh environments
