Customer needs

Detecting all potential damage to tower supports due to aging of existing offshore wind turbine farms.

Customer benefits

Implementation of a predictive maintenance solution making it possible to schedule and anticipate interventions at sea

Cetim answer

Monitoring solution based on Acoustic Emission and Guided Waves for detection of  cracks and sliding of seals between the tower and the Monopile.

Delivered results

• Validation of wave propagation through the joint.
• Demonstration of the frequency filtering at the crossing of the joint.
• Correlation between simulation and tests with respect to propagation mode (speed, attenuation)
• Determination of sensors location
