| Work Detail |
A blade failure happened on Thursday morning on an installed turbine at the Dogger Bank A offshore wind farm, which is currently under construction.
In line with safety procedures, the surrounding marine area has been restricted and relevant authorities were notified. No one was injured or in the vicinity, at the time the damage was sustained.
Developers of the wind farm – SSE Renewables, Equinor, and Vårgrønn – said that they were working closely with the turbine manufacturer GE Vernova which initiated an investigation into the cause of the incident.
Dogger Bank A is the first of the three phases of the UK’s Dogger Bank Wind Farm which is the world’s biggest offshore wind farm under construction and is set to be fully operational until 2025.
The 3.6GW Dogger Bank is being constructed in three 1.2GW phases known as Dogger Bank A, B, and C some 130 km off the coast of Yorkshire.
This is the second blade failure at Dogger Bank involving GE Vernova’s Haliade-X turbine, the same model that is being installed at Vineyard Wind in the waters southwest of Nantucket. The turbine at Vineyard Wind suffered blade damage on July 13.
No one was hurt but the island beaches were strewn with fibreglass shards and green and white foam – over six truckloads of it. More debris was found in the water later on as the state of the blade was deteriorating.
At the time, GE Vernova revealed that the problem was faulty manufacturing, not a design flaw. More precisely, preliminary analysis showed the affected blade experienced a manufacturing deviation in the form of insufficient bonding. |
