Wind turbine yaw ring repair project in Italy
Since 2004, iZanda has been a pioneer in developing innovative solutions for the repair of yaw rings in wind turbines.
For over two decades, our specialized technical team has continuously refined our technological solutions, creating advanced on-site repair systems tailored to various wind turbine technologies and platforms.
Our methodology is based on a rigorous finite element analysis that evaluates stress behavior in transmission systems. We have thoroughly investigated multiple insertion techniques, evaluating different typologies and manufacturing materials to ensure optimal results.
At iZanda, we prioritize durability and technical excellence over merely aesthetic solutions. Our commitment is to provide repairs that offer a prolonged and reliable lifespan, far surpassing the temporary alternatives on the market.
With a global presence and proven experience in on-site yaw ring repairs, iZanda offers solutions that maximize operational performance and minimize maintenance costs for your wind farm.
Yaw Ring, before repair
Fractures are observed on the flanks and top of the teeth.
Yaw Ring, after repair
The affected teeth have been replaced with new metal inserts featuring a ground surface finish and perfect flank geometry. The hundredth alignment of the new profiles with the rest of the ring is evident, ensuring smooth meshing and eliminating the risk of unforeseen stops.
Our method employs precision machining to restore the yaw ring directly on-site, eliminating the need to incur the high costs associated with a complete replacement.
Our specialized portable machine tools make it unnecessary to replace the entire ring, thus avoiding the costly, slow, and risky process of dismantling the rotor and nacelle.
Operated by our expert technicians, our portable machine tools use a repair method with precise tolerances to exactly remove and insert new machined teeth of the yaw ring. This on-site repair eliminates the need for a costly, slow, and potentially damaging disassembly required to change the entire yaw ring gear.
With iZanda’s on-site yaw ring repair, you gain many benefits:
FAQ:
Q: Is it necessary to disassemble the wind turbine for this repair?
A: No. The repairs are conducted on the tower without the need to dismantle large parts or components of the wind turbine. This is one of the main advantages of our method, as it saves a lot of time and costs while avoiding potential damage from disassembly.
Q: What is the process for repairing a broken yaw tooth?
A: The method, developed by our company – iZanda, involves using portable machine tools designed to fit into the limited space surrounding the yaw ring. The process focuses on repairing the teeth using welding, machining, and/or replacement methodologies, offering precision machining and adjustments that restore the full functionality of the yaw ring.
Q: How long does it take to repair a yaw ring?
A: The repair time depends on the number of damaged teeth, type of tower, treatment of the teeth, and other factors such as accessibility to the wind turbine. However, given the experience and specialization of our technicians for these tasks, we can affirm that the work is done as quickly as possible without compromising the quality of the results or the safety of the operators.
Q: Where do you offer this service?
A: We offer our yaw ring repair service worldwide for both onshore and offshore wind turbines.
Q: How much does it cost to repair a yaw ring?
A: Our on-site yaw ring repair service is significantly more cost-effective than a full replacement. The exact cost will depend on the specific damages and the scope of the project, but it will be a fraction of the cost of replacing the entire ring.
