Maintenance-based warranty for offshore wind turbines

Most products are sold with warranties nowadays, including offshore wind turbines. However, these turbines are complex engineering systems located far away from manufacturing facilities, and as a result their warranties are different from those for consumer products. In this paper, we consider maintenance strategies as the major elements in the warranties for offshore wind turbines, which also include timing requirements, charges and coverage. Warranty cost of turbines is analyzed as the combination of maintenance cost and loss of power production. Uncertainties in the analysis are also discussed.
