Title:
FLOATING OFFSHORE WIND POWER GENERATION FACILITY
Document Type and Number:
WIPO Patent Application WO/2014/141911
Kind Code:
A1
Abstract:
[Problem] To make it possible to, in a spar type floating offshore wind power generation facility, suppress a reduction in power generation efficiency due to tilting of a tower, suppress rotational motion (yaw motion) around a vertical axis, prevent a ship from coming into contact with a mooring cable, and at the same time appropriately hold the tilted posture state of the tower. [Solution] A floating offshore wind power generation facility (1) configured from a floating body (2), a mooring cable (3), a tower (4), and a windmill (5) installed at the top of the tower (4) and composed of a nacelle (6) and a plurality of blades (7), wherein the rotation axis of the windmill (5) has a predetermined upward angle in order to avoid contact between the blades (7) and the tower (4), and the windmill (5) is of a downwind type in which the blades (7) are attached to the leeward side of the nacelle (6) and installed with the back surfaces of the blades (7) facing windward, and the mooring point of the mooring cable (3) to the floating body (2) is set at a position below the surface of the sea and higher than the center of gravity of the floating body (2).
