A floating offshore wind turbine includes: a floating body (3); a plurality of wind turbines (1; WTG 1 to WTG 9); a movable mooring mechanism (4, 7) mooring wind turbines (1) on the ocean while maintaining relative positions of the wind turbines (1) and also changing the relative positions; and a control device controlling the drive of the movable mooring mechanism (4, 7) based on a wind direction measured by an anemoscope to change the relative positions of the wind turbines (1) such that a total number of rotors (2) entering a wake flow of another rotor (2) decreases. The movable mooring mechanism (4, 7) is constituted, for example, by a mooring cable (4) and a winding device (7). The relative positions of the wind turbines (1) are changed by providing a floating body (3) for each wind turbine (1) and moving the mooring position of the floating bodies (3), or by providing a single floating body (3) for a plurality and causing the floating body (3) to yaw. |
