Abstract

The report presents the application of a risk and reliability based inspection planning framework (RBI) for the InnWind 20MW reference wind turbine jacket sub-structure. A detailed fracture mechanics based fatigue crack growth model is developed and used as basis to derive optimal inspection plans for the jacket substructure. Inspection plans for different inspection techniques are proposed and recommendations on how to optimize inspection intervals are discussed.
