Maintenance of offshore wind turbine blades has significant impact on the overall cost of managing offshore wind farms. Effective maintenance of protective coatings of wind turbine blades is one of the key challenges of offshore wind farms given that the current condition monitoring systems for wind turbines are limited in detecting coating deterioration. The durability and adhesion of coatings are affected by varying complex offshore weather conditions. This impact is further aggravated as access to offshore wind farms are costly and weather dependent. In this paper an effective predictive maintenance strategy for protective coating of wind turbine blades is developed. The strategy is based on risk analysis approach and coating codes for offshore installations. Practical implementation of the developed strategy will significantly reduces the overall maintenance cost of offshore wind farms.
