External investigation confirms human error behind Vestas blade incident
(ADPnews) - Sep 28, 2010 - Danish wind-turbine maker Vestas Wind Systems A/S (CPH:VWS) said today Norwegian accreditation body Det Norske Veritas (DNV) has carried out an investigation of a blade incident earlier this month and has confirmed that it was a result of a human error.
On September 8, a blade piece detached from Vestas's V112-3.0 MW prototype wind turbine in Lem, on the Jutland peninsula in Denmark.
According to DNV, the incident was due to a human error during the manual production of the blade.
This confirms Vestas's own conclusion, announced on September 10, according to which the failure would not affect serial production as it was not caused by a design flaw. Then the company said it would continue with its marketing and manufacturing plans for the turbine.
The V112-3.0 MW turbine was released for sale in mid-August 2010.
