REQUEST
The requet concerns the execution of a case study focused on monitoring the static and dynamic behavior of an already installed offshore "jacket" type wind turbine. The goal is to create a Digital Twin to assess damage, fatigue and Remaining Useful Life (RUL).
SOLUTIONS
Installing and using s-morpho nodes :
Installation of six IP65 S-Morpho measurement nodes in the tower and nacelle of the wind turbine, accompanied by three additional IP68 waterproof S-Morpho nodes installed on the lattice support.
Digital Twin Creation Processes :
- The acquired data was carefully analyzed using S-morpho software, including :
- Operational Modal Analysis (OMA), including emergent frequency tracking and dynamic deformation reconstruction.
- Static deformation reconstruction for comprehensive evaluation.
- Development of a numerical twin using a finite element model.
- Application of fatigue study algorithms for a thorough investigation.
CONCLUSION
Results obtained with the Digital Twin :
- Real-time structural monitoring (both static and dynamic) synchronized with sea and wind conditions.
- Assessment of damage, fatigue, and Remaining Useful Life (RUL) of the wind turbine.
- Provision of data for intelligent decision making
