Yaw Ring Repair

Yaw ring repair becomes relevant when damaged teeth on a yaw ring affect the wind turbine's ability to turn the nacelle correctly towards the windthe.

The challenge

Worn and broken teeth on the yaw ring can lead to misalignment, increased stress on the drive system and, in the worst case, downtime.

The traditional solution is often to replace the entire yaw ring. This typically requires a crane, longer downtime and significant costs for spare parts, planning and external equipment.

The alternative

At Cetec Energy, we perform yaw ring repair on the uptower. This means that the repair can be carried out directly in the wind turbine without full disassembly of the nacelle.

Using a specialised and proven procedure, the damaged teeth are milled, welded and restored so that the tooth profile again matches the required geometry. The work is carried out with a focus on quality, documentation and reliability.

The result

The method brings the workshop's competences uptower in the wind turbine. For the operator, this means shorter downtime, lower overall costs and a more controlled process than a full replacement.

This type of yaw ring repair can extend the life of a critical component and get the turbine back in production within days - not weeks.
