Corrosion protection for wind turbine units in a marine environment

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 co...

Beschreibung
Zusammenfassung:	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.
