Background
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.
Scientific advances and innovation
The MONEOL project is 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 adaptation of the Morphosense ribbon (developed by CEA Tech) for the reconstruction of curves applied to modal analysis and dynamic measurement of structures
- The system sensors-structure modeling which link the measures with mechanical structure behavioral
- Identification and detection algorithms to monitor the mast structure during the operation of the wind turbine
Expected technical and economic impact
- Predictive maintenance of MRE structures
- Reduced maintenance facility costs (OPEX)
- Remote monitoring and real-time health status
- Extend the life of the offshore installations
Key project milestones
- November 2014 - Project kick-off
- January 2016 - Analysis of wind turbine structure behavior
- January 2017 - Predictive model
Demonstrator
A complete monitoring system will be investigated within the MONEOL project : sensor nodes, data transmission, software and IHM.
Prospects
The MONEOL project is followed by the MONEOL 2 project.
