This invention introduces a kinetic energy recovery wind-wave integrated system for offshore wind power generation. The system consists of a semi-submersible platform equipped with a fan and an internal wave energy device. The device includes a shell housing a Power Take-Off (PTO) system, featuring a permanent magnet synchronous linear motor and an active controller. The motor's stator is fixed inside the shell, while its mover is connected to a counterweight block outside the stator, linked to the shell's top via a spring. Limiters are installed at both ends of the shell to restrict the counterweight block's movement. This system utilizes the wave energy device to absorb kinetic energy, which otherwise affects wind turbine stability, and converts it into usable electrical energy via the PTO system. This enhances the stability and safety of offshore wind turbine power generation.

After being launched, the floating wind power generation equipment under construction is towed to an installation position, and the provisionally mounted members (6, 13, 16) are deployed to the positions at the time of completion. Since the vertical length of the provisional assembly (1a) is shorter than the floating wind power generation equipment at the time of completion, the provisional assembly (1a) is less likely to be affected by wind and waves when towed.
