Effective on-site yaw ring repair 

At 3WIS we have developed our own yaw ring repair procedure that enables on-site repair. Hereby reducing costs and minimizing downtime, with no need for spare part exchange or lifting operations. Replacing the yaw ring usually requires detaching of the nacelle through cranes, involving a large amount of resources. 

Our yaw ring repair procedure is performed on-site, repairing only the worn-down teeth, and thereby reducing the downtime of the turbine to only a few days.

The procedure is certified and approved in accordance to ISO and EN standards. As an OEM or owner & operator of assets, minimizing maintenance cost and maximizing your assets availability and performance is essential. 

Furthermore, our yaw ring repair method contributes to enhanced sustainability, through a faster repair proces and a smaller impact on the environment.
