Title:
FLOAT STRUCTURE FOR OFFSHORE WIND POWER GENERATION
Document Type and Number:
WIPO Patent Application WO/2023/234287
Kind Code:
A1
Abstract:
A float structure (5) for offshore wind power generation comprises a float base (10) on which a wind turbine tower (1) is vertically installed and which is divided into a plurality of air chambers (11), and an air amount adjustment unit (20) which adjusts the amount of air in the air chambers (11) that are opposed to each other across the center of the float base (10). Each of the air chambers (11) comprises an open bottom portion and a soft film body (16) in slackened state that partitions the interior of the air chamber (11) into an air layer (17) and a water layer (18). Thus, the floating body structure (5) can be installed in any location, provides excellent stability, and may be suitably used for very large-scale wind power generation on the order of 20 MW or more.
