Abstract: A wind energy-wave energy-tidal energy integrated power generation system based on monopile foundation, in which the wind energy, wave energy and tidal energy will share the support structure and power transmission system, belongs to the technical field of ocean renewable energy utilization. An integrated power generation system which integrates wind energy converter, oscillating water column wave energy converter and horizontal-axis tidal energy converter is established based on the monopile support structure. The invention makes sufficient use of offshore renewable resources, so as to improve the utilization ratio of monopile foundation and reduce the total cost of power generation of integrated system. The novel integrated power generation system improves the effective utilization of the ocean areas, reduces the cost of construction and maintenance, makes full use of the existing mature wind energy technology, and promotes the commercialization of wave energy converters and tidal energy devices.

Abstract: A very large floating structure based on modular units and a combined mooring system. The system includes a central large platform module, small outer platform modules, tension-legs, mooring lines, oscillating float-type wave energy converters and module connectors. The oscillating float-type wave energy converters can convert the swinging motion of the floaters into the horizontal motion of the piston rods through the gear wheel-rack transmission. Module connectors between modules are divided into two kinds of modes. One can utilize both relative torsional motion and horizontal motion between the central large platform module and the adjacent small platform modules, while the other simultaneously generates power and reduces the relative motions between the adjacent platform modules. The wave energy converters on the outer modules of the very large floating structure can generate power by absorbing the incident wave energy.

Abstract: An anti-swing device for offshore wind turbine tower installation which reduces pendular motion of the tower component during mating process. Subsystems are at the transition piece, tower, and bridge. Winches are arranged on and fixed to the tower's inner wall and connected through cables. A remote signal transceiver and acquisition controller are arranged and fixed to the tower's inner wall. The transceiver controls the connector at the tower end and servo winch motors which control the cables to adjust the position of the suspended tower component. The controller acquires tension signals on the cables from the tower and transmits signals to the transceiver. Acceleration sensors are included in the acquisition controller. Several connector are included in the tower end and fixed at the bottom of the tower component. The number of connectors is the same as winches at the transition piece and their positions correspond.

Abstract: A hub mating mechanism for single blade installation of offshore wind turbines. The mechanism includes a rigid circular snap ring having circumferential contact with the hub, spring damper, force actuator, buffer plates made from resilient composite material, controller and electric motor. The ring is connected to the buffer plates through the spring damper and the force actuator. The roots of the buffer plates are connected to the outer edge of the hub by hinges. The force actuator is driven by the controller and electric motor placed in the nacelle. Multiple flange holes are formed in the blades and the hub fixed together through bolts after the mating is completed. Assembly and testing of the hub mating mechanism can be performed during component assembly onshore. The hub mating mechanism includes the circular snap ring, buffer plates, force actuator, spring damper, controller and electric motor which are off-the-shelf commercial products.
