Wind turbine collapse accident

Failure analysis and risk management of a collapsed large wind turbine

After the wind turbine collapsed, the rebuilding costs were adversely affected by price inflation; thus, the original price of the turbine increased to US$3.2 million from US$2.5

Siemens Gamesa blade collapses at troubled wind farm in Norway

The collapse of the 71-metre-long (232 ft) wind turbine blade comes at a time when nearly half of the machines at the site are not working amid an ongoing process conducted by turbine maker

Vattenfall reveals cause of Dutch wind turbine collapse

Vattenfall reveals cause of Dutch wind turbine collapse. Vattenfall has concluded a probe into why a two-bladed wind turbine at one of its Dutch wind farms collapsed in stormy conditions earlier

Germany: Wind turbine collapses hours before official

BERLIN (AP) — Officials in Germany are investigating why a huge wind turbine collapsed just hours before it was due to be officially inaugurated. The turbine, whose rotor blades reach a height of 239 meters

Chinese turbine collapse and ''serious casualty'' prompts order for

The collapse of a wind turbine in China has prompted a state authority to order a daylong shutdown of projects in the region to tackle safety failings. The Xinjiang Supervision

Turbine down | Collapse and oil spill shuts one of

RWE said in a statement sent to Recharge: "We can confirm that one wind turbine collapsed on Saturday at the Nysäter wind farm, about 400km north of Stockholm. No one was injured in the accident. The country

''Serious event'' | Vestas turbine collapses at Iberdrola wind farm

6 FAQs about [Wind turbine collapse accident]

How common are wind turbine collapse accidents?

During the past decades, wind turbine tower collapse accidents have been frequently reported worldwide . Chou and Tu [26,28] conducted an in-depth investigation of tower failure, along with the lessons learned from a post-disaster inspection.

What happens if a wind turbine tower collapses?

Upon tower collapse, all bolts connecting the lower and middle parts were broken into pieces and scattered over the ground. To identify the collapse mechanism, the strength of intact bolts randomly torn from nearby wind turbine towers and fractured bolts from the collapsed tower was tested in the laboratory. Fig. 9 shows the test device. Fig. 9.

What caused the collapse of a wind turbine at Kent Hills?

A wind turbine at the Kent Hills wind farm was found collapsed across an access road. (Submitted by Steve Shannahan) An investigation into what caused the collapse of a wind turbine at New Brunswick’s largest wind farm has revealed serious structural issues that affect not only the turbine that fell, but dozens of others in the area as well.

How to identify the collapse mechanism of a wind turbine?

To identify the collapse mechanism, the strength of intact bolts randomly torn from nearby wind turbine towers and fractured bolts from the collapsed tower was tested in the laboratory. Fig. 9 shows the test device. Fig. 9. The experimental device for testing bolt strength.

What happened to a wind turbine?

Due to the strong winds, the middle part snapped and deformed when it hit the ground. The nacelle and shaft collapsed and were destroyed. The wind turbine owner contacted the insurance company for a site inspection. The insurance company then employed an adjuster and surveyor company to conduct an independent investigation and estimate loss.

What are the failure modes of wind turbine tower collapse?

4. Structural re-analysis of the wind turbine tower Failure modes of tower collapse are excessive deformation, fatigue, fracture, yielding, and plastic collapse , . The aim of structural re-analysis was to predict tower response under different wind loads specified in original design and current domestic specifications.
