Detection of surface imperfections and structural abnormalities on wind turbine rotor blades before they become serious and causes complete failure is crucial.

Condition inspection of installed blades

Heavy wind and environmental conditions have a great impact on blade surfaces and laminated rotor blade structure. Due to different load and stress situations, damages like erosion, delaminations and cracks can appear. To prevent critical damages or even complete failure, the condition of the blades should be inspected regulary, utilizing different non-destructive inspection methods, e.g. visual and thermal infrared inspection techniques.

Periodic examination of the FRP rotor blades, with a visual and infrared imaging system, can detect operational problems before they become serious and allow for effective response planning. In this mode of operation, those inspection techniques are valuable predictive maintenance tools.
