Innovative And Sustainable Corrosion Protection Solutions For Foundation Structures Of Offshore Wind Turbines

Metallic coatings as a protective coating are characterized by excellent corrosion protection behavior and show extreme resistance to mechanical loads as well. Pure metallic coatings or duplex systems are already being used successfully in other areas of offshore structures. For example, areas in the tidal water zone, such as boat landings, usually receive a duplex system consisting of thermal spayed coating and a fitting topcoat. Add-on parts are often protected exclusively by a metallic zinc coating. A thermal spray coating in the submerged zone thus represents a logical alternative to the organic topcoat system.

The steel structures of offshore wind turbine foundations have so far only been protected cathodically (galvanic anodes/impressed current systems) in the underwater area. More recent German regulations recommend an additional coating in order to reduce the required anode masses (1). In most cases, organic top coatings are used for this purpose, which significantly reduces the necessary protective current requirement. However, organic top coatings lose their barrier protection effect due to damage, defects and ageing, which increases the protective current requirement again. Mechanical loads already during transport and installation ("pile driving"), as well as (hydro-)abrasion by sand near the seabed during the period of use, make it useful to consider the tribological properties.
