Understanding Main Bearing Failures – Mitigating a $150K – $300K O&M Cost
Dr. Arnab Ghosh demonstrates Sentient’s New Main Bearing Wear Model.
The presentation features:
- New capabilities in the DigitalClone Live software that predict early wear initiation in the main bearing raceways and rollers.
- How to understand the current health of the main bearing in a particular asset to mitigate damage prior to failure.
- How to reduce the cost of repair, currently ranging from $150K – $300K for each occurrence, and reduce the amount of downtime.
According to a report by Windpower Engineering & Development, the cost to repair main bearings is one of the highest compared to other turbine systems ranging from $150,000 to $300,000. As fielded turbines age, the aggregated downtime has increased to more than 20,000 hours.
