Wind turbine yaw ring repair project in Great Britain

At iZanda, we are dedicated to high-precision on-site machining solutions. In the wind energy sector, one of our specialties is the restoration of yaw rings for wind turbines, both onshore and offshore.

Since our founding in 2004, our team of engineers has led innovations in specialized machine tools for the recovery of these key components in wind turbines.

Our primary commitment is to perform on-site repairs that endure over time, beyond mere superficial corrections.

The “before” and “after” images are the best testament to our intervention capability. While the initial state showed severe degradation compromising the wind turbine’s operability, our precision on-site machining solution restored the component to its original geometry and strength.

FAQ:

Q: How do you ensure that the new “insert” of the teeth does not detach under load?

A: We use a method of mechanical and metallurgical fixation based on prior stress studies. The materials of the inserts are designed to withstand torsional loads greater than the originals, ensuring that the joint is the strongest point of the transmission, not the weakest.

Q: What precision do your portable machines achieve when working at great heights?

A: Our portable machine-tools are specifically designed to rigidly anchor to the turbine structure. This allows us to achieve micron-level precision, equivalent to what would be obtained in a conventional machining workshop, but directly on the tower.

Q: Is it a temporary or permanent solution?

A: It’s a permanent repair. Our aim is not to “patch” the failure just to get by, but to restore the yaw ring’s lifespan. Repairs carried out by iZanda have remained operational in extreme conditions worldwide for years.

Q: Can you perform this work in adverse weather conditions like those in the UK wind farms?

A: Yes. Our team is accustomed to working in complex environments, both in mountain wind farms (onshore) and offshore. The portability of our equipment allows us to operate within the tower or nacelle itself, protected from the elements.

These images illustrate the transformation achieved through our on-site process, restoring full functionality without compromising structural integrity.

With iZanda’s on-site yaw ring repair, numerous benefits are obtained:

  • STRUCTURAL COST SAVINGS:
    We eliminate the need to rent heavy-duty cranes and the risk associated with dismantling main components.
  • QUICK RESPONSE
    The wind turbine returned to generating power in record time, minimizing losses due to downtime.
  • SUSTAINABILITY
    By repairing instead of replacing, we reduce the carbon footprint and the waste of large metal parts.

Is your wind turbine halted due to gear ring tooth failures?

Don’t let logistics costs and large crane rentals drain your park’s profitability. At iZanda, we transform critical failures into operational solutions in record time through precision on-site engineering.
