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.
Solutions for critical projects in the energy sector
Cetec Energy empowers operators and OEMs by adding specialised expertise, precision and capacity to ensure wind turbines operate optimally.
Specialised welding for wind
The team specialises in performing Repairs and welding tasks that extend the life of critical original components and reduces the need for replacement.
Through targeted interventions directly in the tower and nacelle, damage and wear can be effectively repaired to restore component function and structural integrity.
This approach minimises downtime, reduces costs and ensures that the turbine can be quickly brought back into operation - without compromising quality or safety.
All technicians are GWO certified and have extensive practical experience of welding under the conditions that characterise working in wind turbines.
Specialised welding for marine
Cetec Energy provides specialised welding solutions for the marine industry, where work on Primary structures, engine components and critical systems requires high precision and safe execution. Tasks include repair, modification and installation carried out directly on the vessel - often as an integral part of planned operations or short-term stops.
The work is carried out in close interaction between welding and mechanical competences, enabling efficient interventions on complex systems without unnecessary interruptions. The structured approach, clear division of responsibilities and experience with demanding marine environments ensure that tasks are carried out efficiently, in a controlled manner and with full focus on function, safety and long-term solutions.
