Broken wind blades

Did GE vernova break a wind turbine blade?

Link Copied! Giant wind turbine blades for the Vineyard Winds project are stacked on racks in New Bedford, Massachusetts. The massive offshore wind turbine blade that broke and spread fiberglass and foam debris across Nantucket beaches this week was one of several recent failures of blades made by GE Vernova – a top US wind turbine manufacturer.

Why are wind turbine blades breaking?

“It is clear that major (manufacturers) have all faced blade breakages,” Mukherjee said in an email. The failures were caused by issues such as design flaws and manufacturing lapses by contractors, he said. As the global wind energy industry grows, the size of the turbines themselves are also growing.

How many turbine blades are broken?

The total number of broken turbine blades has been relatively low compared to the large number of blades manufactured each year. Wind farm developers ordered around 20,000 turbines – each with several individual blades – in 2023. “If we consider that for scale, then the failure rate remains low,” Mukherjee said.

What happened to Vineyard Wind turbine blade?

The massive turbine blade – as long as a football field – was part of the Vineyard Wind farm off the coast of Massachusetts and its islands, Martha’s Vineyard and Nantucket. The blade was “broken” and “folded over” on Saturday, Vineyard Wind CEO Klaus Skoust Møller told Nantucket residents and officials at a public meeting Wednesday night.

Can a liquid solution break down wind turbine blades?

Danish company Vestas, the largest wind turbine producer in Europe, announced last year an approach that uses a liquid chemical solution to break down the blades into materials which can then potentially be used to make new blades.

How are wind turbine blades made?

Instead of using cloth to catch the wind like Prof Blyth and the ancient Iranians, today's turbine blades are built from composite materials - older blades from glass fibre, newer ones from carbon fibre. Such composite materials might be light and strong, but they are also extremely hard to recycle.
