Yaw rings are a vital component for power production. However, worn-down yaw rings are a common challenge, often requiring taking down the nacelle and replacing the entire yaw ring - An extensive and costly repair, causing critical downtime for the wind turbine. 

At 3WIS we offer a welded repair solution performed both on- and offshore with no need for removing and replacing the entire yaw ring. Our certified yaw ring repair procedure, including pre and post inspections, is performed onsite, repairing only the worn-down teeth, and thereby reducing the downtime of the turbine to only a few days.
