Case Study: Vestas avoids major generator bearing failure with Delfos Energy Prediction Module

Vestas prevents bearing loss with Delfos after 3 months of early warning

Vestas faced a potential critical failure when a thermal deviation was detected in the generator-coupled bearing of a V100 wind turbine model. The challenge was to monitor the degradation and prevent the total loss of the equipment. Delfos Energy's Prediction module provided the early identification of this anomaly.

The solution implemented by Delfos Energy involved using its Prediction module for early fault detection and Neighbour Analysis to confirm the issue was isolated. This provided a 3-month lead time, allowing for strategic monitoring and a planned intervention. The results were a controlled bearing replacement and generator shaft grinding, avoiding a serious failure and limiting turbine downtime to just 9 days.
