Abstract
The anti-corrosion performance of coating systems (cathode protection, organic coating, and duplex coating) applied to prevent the corrosion of offshore wind power plants was assessed. As an assessment method, the adhesion strength of each coating system was evaluated after exposing the coatings to the marine environment and an indoor salt spray test. It was confirmed that the adhesion strength varied depending on the exposure period, and the deterioration of adhesion strength was related to the fracture type of each coating layer. In addition, the fracture type of each coating system was analyzed and the adhesion strength was corrected according to the fracture type. The corrosion rates after exposure to the marine environment and indoor salt spray were compared and examined using the corrected values.
Highlights
Offshore wind power plants are several tens of meters in height, more than 5 m in diameter, and several centimeters in outer wall thickness, and about 89% of them are made of steel materials.In such plants, the tower and jacket structures form the support structures
The variation in the adhesion strength of anti-corrosion coating systems applied to offshore wind power plants was measured and assessed after 365 days of exposure to a marine environment and 15 days of indoor salt spray test (CASS)
The corrosion damage to the coating systems under marine environmental conditions was assessed by exposing the coating systems to sea at a site located in Daebu Island, Korea
Summary
Offshore wind power plants are several tens of meters in height, more than 5 m in diameter, and several centimeters in outer wall thickness, and about 89% of them are made of steel materials. In such plants, the tower and jacket structures form the support structures. The corrosion protection coating system used for each zone of an offshore wind power structure is based on the environmental conditions of each zone; for example, the influence of the high weather ability, temperature, salt spray and wetting should be considered for atmosphere-exposed zone. This study analyzed the adhesion performance of coating system (surface protective paint, metal spraying, duplex coating) applied for corrosion protection in offshore wind power structures. Through the test, which comprised a long-term exposure of coating samples to marine conditions and to brine conditions indoors, the adhesion performance maintenance lifetime of coating systems for offshore wind power structures were analyzed
