CNC Onsite’s Innovative Yaw Ring Repair Method

Søren Kellenberger, sales director at CNC Onsite, joins the Uptime Spotlight to discuss their uptower yaw ring repair method. He describes the root causes of yaw ring failure, makes projections for the future, and introduces CNC Onsite's patented yaw ring repair solution. Their portable precision machine can be lifted uptower to replace a damaged yaw ring, potentially saving operators significant downtime and repair costs.

Hire a crane for a complete replacement or attempt a risky repair. This week we speak with Søren Kellenberger, sales director and partner at CNC Onsite. CNC Onsite brings precision machining up tower. Making yaw gear repairs faster and more reliable without using an expensive frame. Welcome to Uptime Spotlight. Shining light on wind energy's brightest innovators. This is the Progress Powering Tomorrow. Allen Hall: Søren, welcome to the show. Thank you very much, Allen. And thank you for inviting me. Well, we want to understand first, what is causing yaw gear to break? teeth to be damaged in some of these turbines, because the photos I have seen are remarkable. The teeth are just gone. How does that happen? Søren Kellenberger: I think there can be a number or there can be a number of reasons. And it, it depends a little bit, I think, on the turbine, how the yaw ring was designed and stuff like that. But if you look at some of the older turbines the yaw ring. Wasn't hardened. So there, in many cases, you'll just see wear and tear from years of of use, operation. And typically in a, in a wind farm, you have a dominating wind direction, right? So, Especially in Denmark, it's mainly blowing from the west. So all our wind turbines are pointing that direction most of the time, which means that they are yawing within a limited are...
