Research Progress of Anti-Corrosion Technology for Offshore Wind Power Facilities

Abstract

Offshore wind power is a kind of green energy, which has attracted more and more attention. The anti-corrosion technology of offshore wind power facilities has become a current research hotspot. This paper first expounded the corrosion mechanism of equipments in the marine environment, and then introduced the commonly used anti-corrosion technologies for offshore wind power facilities, including the anti-corrosion coatings, cathodic protection, reserved corrosion allowance method, etc. Then, combined with an example, the anti-corrosion technology of thermal spraying and mineral grease coating in the new anticorrosion method in splash area were introduced emphatically. Finally, it briefly described the anti-corrosion detection and maintenance means of wind power facilities. It also introduced the corrosion protection methods used in Guishan wind power project in Zhuhai, Guangdong, which has been built into grid connected power generation in China, in order to provide some suggestions for improving the anti-corrosion level of offshore wind power.
