An offshore wind turbine is set in a highly corrosive marine environment. Its base structure is completely immersed in the seawater. Conventional corrosion prevention methods use both a cathodic protection and a coating method to enhance corrosion protection to protect the structure. Cathodic corrosion protection is an electrochemical process applying the principles of electrochemical cells transforming a metal material into a cathode. There are two types of cathodic protection: “applied current cathodic protection” and “passive galvanic cathodic protection”. The development . . .
