Periodic vibration monitoring

Monitoring the condition of wind turbines is crucial for ensuring their longevity and operational availability. Vibration monitoring is one of the most accurate methods for detecting developing damage at an early stage. Istec offers services to periodically perform vibration analysis, providing accurate insights into your asset’s health.

We prioritize data acquisition systems that enable remote vibration analysis, optimizing cost-effectiveness in machine insights. However, when onsite data acquisition is necessary, our team is fully equipped and ready to visit and directly assess the wind turbines.


Many wind turbines in Europe are reaching the end of their lifecycle, and as new wind turbines become larger and heavier, these developments can lead to unexpected operational issues. Our goal, through our vibration troubleshooting services, is to identify the root cause.

End of Warranty analysis

Our End of Warranty analysis service is designed for wind turbine owners to deliver a brand-independent assessment. As warranties approach expiration and maintenance responsibility shifts to the owner, our analysis provides an objective evaluation of turbine health.

Case study: Vibration monitoring and analysis on wind turbines in the Netherlands





Windunie is a collaboration between owners of wind turbines throughout the Netherlands. The warranty of some of the wind turbines at one of their wind parks was expiring at the end of 2022. Windunie has engaged Istec as brand-independent vibration specialist to monitor the condition of the turbines.

When the warranty of a wind turbine is about to expire, a final inspection is conducted by the manufacturer (OEM) of the turbine to assess their mechanical condition. During this inspection multiple parameters are measured and analyzed to determine the condition of the wind turbines.

To ensure additional insight into the mechanical condition of the wind turbine drive train and the effectiveness of the condition monitoring program, Windunie has contacted Istec, as independent third party, to conduct vibration analyses on two Vestas wind turbines.
