Nordsee One Offshore Wind Farm

30 Jun 2021: Issues with the coating on the Main Rotor Shaft Bearings in NS1’s 6 MW Senvion turbines in Germany are impacting performance. Shafts of the eight most affected turbines are being replaced in 2021, with a phased broader campaign lasting into 2023. Lost revenues due to curtailment are estimated at €11m for 2021.The remaining machines have been de-rated to extend life until a suitable weather window for repair is available. Jack-ups have been secured. The estimated capital cost to replace components on all 54 turbines is €65m, of which €54m is covered by a bonded warranty provision secured from Senvion upon its insolvency.
