During the first year maintenance for Øyfjellet Wind Park, we found some minor deviations which needed addressing.
In one of the 72 windmill foundations the client discovered reduced active force, during the lift-off test in some of the rock anchors.
After using Fatbar M64 tensioners to complete new lock-off for all rock anchors the foundations, active force was up to 100% again.
“The operation went smoothly and according to plan, there were no issues with re-tensioning the anchors with new lock-off to achieve 100% active force levels. The customer was very happy with the outcome”
