摘要
A floating multi-turbine wind power platform for offshore power production, wherein the platform has a substantially elongated shape with an extension direction and being attached to at least two mooring points for securing the platform at its operation site in an original position in relation to the mooring points. The platform includes a device for rotation of the platform (MR1) around an essentially vertical first axis (z1) and further includes at least two wind turbines arranged substantially in a straight line corresponding to the extension direction of the platform and the at least two wind turbines each includes a structural support component and a rotor component. The rotor component is attached to a nacelle which is arranged to rotate using a device for rotation of the nacelle (MR2). The platform further includes a control arrangement (C) arranged to control the device for rotation of the platform (MR1) to rotate the platform only during certain detected wind directions deviating from an original wind direction (WDO) and to limit the rotation of the platform to at the most 90° from the original position, preferably at most ±45°. A method and system are disclosed for aligning rotor components of wind turbines arranged on a floating multi turbine wind power platform according to the above to be essentially perpendicular to a wind direction.
