Abstract
A corrosion protected wind turbine unit includes a wind turbine unit support structure or foundation implanted in water and an impressed current anode electrochemically coupled to the wind turbine unit support structure or foundation through the water. Also included is a controlled current source configured to receive electrical current from the wind turbine unit or at least one other wind turbine unit located in proximity to the corrosion protected wind turbine unit and further configured to operate the impressed current anode.
Claims10
A method for protecting a wind turbine unit support structure or foundation from corrosion, said method comprising:
- providing an impressed current anode electrochemically coupled to the wind turbine unit support structure or foundation;
- and
- applying a current obtained from at least one wind turbine unit on the wind turbine unit support structure or foundation, a current obtained from a power supply coupled to the at least one wind turbine unit, to the impressed current anode to operate the impressed current anode.
