Based on the anti-corrosion function, the anti-collision function of the jacket of the offshore booster station is strengthened in the anti-corrosion engineering of the offshore wind power project. The design, preparation and fixing of the special shape corrosion protection cover are optimized. The prefabricated structure is overlapped with the protective cover prepared on site. The problem of coating and anti-corrosion of large-size and special-shaped structures is solved.
