Pre-assembled wind turbine for offshore applications

摘要

A fully assembled wind turbine for offshore applications, where the wind turbine is fully assembled and then transported via a ship to the required location to be connected to the system. Preferably, the wind turbine can be installed on any platform or foundation, such as a floating bed, and the wind turbine may comprise counter or contra rotating dual rotors to reduce the gyroscopic effects. The blades may comprise carbon fibre and be reinforced with Kevlar and there may only be 2 blades on each rotor. Preferably the tips of the blades have a built I weak point to allow the tip to bend completely backwards above a speed of 4 m/s to reduce wake related effects. The front hub may move horizontally towards or away from the rear hub to increase or decrease slip stream effect.
