A Vestas wind turbine is reported to have collapsed in Sweden in 2015. An industry news report published in February 2017 states that failure of the tower bolts led to the collapse. The site, turbine model, capacity, date and whether anyone was hurt are not reported in the available source material, which is a headline and feed summary only.
Failure of tower bolts, according to the headline of the industry report. No further technical detail is available in the source.
- Bolted tower connections are a load path whose integrity depends on correct installation and torque, and should be covered by inspection regimes.
- Operators should track published structural failure findings for their turbine types and check whether the same connection details apply to their fleet.
- Publishing sufficient technical detail from structural failure investigations helps other operators assess comparable risks.
