Fatigue loading of offshore wind turbines is an interaction of wave loads, wind loads and the first structural modes of a wind turbine substructure. The design of most offshore wind turbines on monopile(MP) foundation is driven by the fatigue life of the welded connections in the MP. As a result of design optimization typically the first welds beneath the sea bed are most fatigue critical and determine the lifetime of the offshore wind turbine. Accurate information about damage progress is essential for O&M strategies but also for further design optimization while both visual inspections and sensor installation are not favorable for those locations.
