Abstract: This article provides an overview of the present situation of corrosion protection of offshore wind power structures, which Includes: Offshore wind farm structural materials, anti-corrosion design, anti-corrosion maintenance measures; Then provides an overview of the domestic and international research progress about the corrosion mechanism, typical corrosion damage and corrosion fatigue risk of marine environment, which Includes: Galvanic Corrosion of High-strength low-alloy steel, low carbon steel, stainless steel, aluminium alloy and other structural materials commonly used in offshore wind farm, influencing factors and characteristics of marine fouling and microbial corrosion, and the research progress of corrosion fatigue life prediction. It provides an effective reference for the research direction of offshore wind power structure in service life.
