The challenge
Damaged teeth on the pitch gear can quickly put a turbine out of operation. Even small defects lead to misalignment, higher loads on the drive system, and in the worst case, a complete standstill. The standard solution may be replacing the entire pitch yawing ring – a process that demands craning, extended downtime, and significant component cost.
The alternative
At Cetec Energy, we approach the problem differently. Our teams carry out precision repairs up-tower. With a specialised and tested Yaw Ring Repair Procedure the process a welding repair is conducted up-tower, and the damaged teeth are rebuilt and restored without dismantling the nacelle.
The result
This method brings the workshop into the turbine. It is faster, far more cost-effective, and extends the service life of critical components. For operators, it means reduced downtime, controlled costs, and turbines that are back in production within days - not weeks.
