Status of Corrosion and Protection for Offshore Wind Towers

As a clean technology of energy utilization,offshore wind power has become a hot topic of renewable energy in the world.The offshore wind turbines and especially the towers suffer from serious corrosion due to the extremely harsh marine environment,therefore the corrosion protection has become a major problem in offshore wind power design.The research progress of zinc-rich coatings and polyurethane coatings as anticorrosive coatings of offshore wind towers are reviewed in this paper,and the corrosion and anticorrosion design are also discussed.The comprehensive performance of the anticorrosive coatings modified by nanometer materials and corrosion inhibitors can be obviously improved,which provides a feasible corrosion protection for the offshore wind towers.
