As wind turbines age, wear and damage within the yaw system can become a significant challenge for operators seeking to extend the operational life of their assets. Traditional repair strategies often involve major component replacements, extensive crane operations, and prolonged downtime.
CNC Onsite has developed a comprehensive on-site repair methodology that restores critical yaw system interfaces directly inside the turbine, providing a practical and cost-effective alternative to component replacement.
Complete on-site yaw system restoration
The solution combines multiple specialized repair methods targeting the most critical yaw ring components:
- Yaw ring teeth repair
- Yaw sliding surface refurbishment
- Yaw gear mounting flange repairs
Together, these methods allow damaged components and interfaces to be restored on-site without removing the yaw ring from the turbine.
Supporting lifetime extension strategies
For many operators, replacing large yaw system components can be difficult to justify economically, particularly for turbines approaching the end of their original design life.
By restoring critical surfaces and mounting interfaces directly on-site, turbine owners can:
- Extend operational lifetime
- Reduce replacement costs
- Minimize downtime
- Avoid heavy lifting operations
- Improve long-term reliability
The combined repair methodology enables owners to maximize the value of existing assets while maintaining safe and efficient operation.
A sustainable alternative to replacement
As the wind industry continues to focus on asset optimization and sustainability, repair and refurbishment solutions are becoming increasingly important alternatives to major component replacement.
Through advanced on-site machining, specialized repair technologies, and continued innovation, CNC Onsite is expanding the possibilities for yaw system refurbishment and helping make wind turbine lifetime extension both technically and economically viable.
