The technology called SHM (Structural Health Monitoring) is used to maintain the product quality in the time. Their main objectives are to ensure the health of structures, extend their life and to anticipate their failures. SHM is therefore part of a strategy that is both economical and safety.
The MONEOL 2 project follows previous work (MONEOL project) focused on the instrumentation of an on-shore wind turbine with an inertial sensor network whose responses allow the detection of vibration modes specific to the wind turbine, in particular the mast, and real-time monitoring of these responses.
The MONEOL 2 project, funded by WEAMEC, involves the CEA Tech (coordinator) and Université Gustave Eiffel.
Scientific advances and innovation
There is several objectives of this project: to bring this work to offshore wind turbines; search for signatures in wider frequency bands; study the response of offshore floaters and their mooring.
One of the challenges is to find the signatures of rotating elements (blades) without direct instrumentation. Instruming these elements is indeed more expensive and more impacting on the structure.
In addition, the sensor technology will be suitable for monitoring the fatigue life cycle of moving wire structures (dynamic electrical connection cable and mooring) in the case of an off-shore wind turbine.
The ultimate goal is to propose a global method of health monitoring for offshore wind turbine.
