Vestas focuses on bolting in 3MW turbine collapse probe

Today it said preliminary findings suggest “that the turbine collapse was caused by a failure in the bolted flange between tower sections one and two”. Examination by an external metallurgical laboratory does not indicate a bolt quality issue, said Vestas, and “the ongoing investigation is focused on the bolt pre-tensioning procedure”.

Vestas says a failure of bolting between tower sections is the likely cause of the collapse of one of its 3MW turbines in Sweden.
The wind OEM has been investigating since the V112-3.0 MW came down on Christmas Eve at the Lemnhult Wind Farm operated by Stena Renewable – the first such incident involving a Vestas MW-class machine.

Vestas says a failure of bolting between tower sections is the likely cause of the collapse of one of its 3MW turbines in Sweden.
The wind OEM has been investigating since the V112-3.0 MW came down on Christmas Eve at the Lemnhult Wind Farm operated by Stena Renewable – the first such incident involving a Vestas MW-class machine.
Today it said preliminary findings suggest “that the turbine collapse was caused by a failure in the bolted flange between tower sections one and two”.
Examination by an external metallurgical laboratory does not indicate a bolt quality issue, said Vestas, and “the ongoing investigation is focused on the bolt pre-tensioning procedure”.
No one was injured in the collapse, which saw the other 31 turbines at Lemnhult taken out of service as a precaution.
The Danish manufacturer said: “Vestas has installed more than 55,000 turbines globally, and incidents involving turbines’ structural integrity are very rare.
“We have not experienced a MW-class turbine collapsing before. We will provide additional information when it becomes available.”
