Vertical-axis wind turbines (VAWTs) have inherent advantages over horizontal -axis wind turbines (HAWTs) resulting from the low center of gravity primarily caused by the low height of the drivetrain relative to the rotor. The low center of gravity is one of the main drivers for development of VAWTs for floating offshore wind energy generation, where the reduced center of gravity has positive system benefits by reducing the demands placed on the floating platform and its associated mass and cost. This advantage for VAWTs can be further enhanced by lowering the elevation of the drivetrain by housing it within the platform column.

In a general aspect, a submersible barge includes a deck having a support surface and an additive manufacturing system. The submersible barge may be deployed on a body of water. The additive manufacturing system is configured to fabricate a cementitious body on the support surface by successively depositing layers of flowable cementitious material on top of each other. The submersible barge also includes a buoyancy system that is configured to lower the cementitious body into the body of water by altering a draft of the submersible barge between first and second drafts. When the submersible barge is at the first draft, the support surface resides above a surface of the body of water. When the submersible barge is at the second draft, the support surface resides below the surface of the body of water.

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.
