However, due to the deployment of offshore converter stations in high-salt and high-humidity offshore environments, the steel structure of the converter station is exposed to high-salt and high-humidity marine environments for a long time, and the metal corrosion rate is relatively fast. At the same time, there will be the attachment of marine organisms such as barnacles and oysters, which not only increases the structural load, but also accelerates the electrochemical corrosion process. Long-term challenges include seawater corrosion and marine organism attachment. If not properly protected, it may lead to a decrease in structural strength, equipment short circuits, and even collapse, which will directly threaten the grid stability and power continuity of offshore wind farms.
