How Teut planned a main bearing exchange with Turbit
A main shaft bearing temperature anomaly appeared on a Teut turbine on April 9th, 2022. Temperatures stayed under control through summer; by November 2022 they had escalated. Teut and the OEM confirmed bearing damage and planned a main component exchange within five months — keeping the turbine operational until the scheduled service window. Severe damage prevented, downtime avoided.
Thanks to Turbit, we were able to respond promptly to temperature issues and prevent damage to our turbine. Their solutions ensure optimal performance, and we appreciate their open communication and regular updates.
Detection of anomalies and investigation
Turbit's monitoring system detected a change in the normal behaviour of a wind turbine on April 9th, 2022 and immediately issued an alarm. The Turbit team investigated to identify the root cause: the main shaft bearing was running at high temperatures from April 2022 onward. Turbit promptly informed the wind park operator.
Root cause analysis and OEM response
Temperatures were kept under control during summer 2022. From the beginning of November 2022, however, Turbit identified a significant increase. The wind park operator was informed immediately and escalated the matter to the OEM. On November 30th, the OEM confirmed that the main bearing was slightly damaged and initiated processes to organise the replacement within a main component exchange action over the next five months. A flushing of the main bearing was performed and an additional second grease pump was installed to prevent further damage in the meantime.
Collaboration, maintenance strategy and value for Teut
Throughout the resolution process, Turbit closely collaborated with the wind park operator, providing continuous tracking and monitoring services. This kept the turbine operational until the scheduled main component exchange could be carried out. The Turbit team maintained open lines of communication, delivering regular updates on the turbine's status and promptly sharing any changes — proactive planning that prevented potential downtime and mitigated the risk of more severe damage.

Main Bearing MonitoringVSB acts on a main-bearing temperature trend in one month
Turbit's neural networks caught a slow-creeping main-bearing temperature trend a year before action was needed. By the time the deviation was clear, VSB and the OEM resolved it inside a month — without taking the turbine down.
