November 22, 2024 — Last summer’s structural failure of a single blade on a southern New England offshore turbine continues to reverberate, with new demands for quality assurances and the industry under pressure from incoming president Donald Trump’s promise “to make sure” offshore wind power “ends on day one.”
Allegations that testing data was falsified at LM Wind Power’s plant in Gaspé, Quebec, where the blade was manufactured, are being investigated as part of ongoing probes into the July 13 failure of a turbine blade at the Vineyard Wind project off Nantucket Island, according to reporting by Canadian news media outlets in late October.
Turbine manufacturer GE Vernova identified a “manufacturing deviation” in the blade built by LM Wind Power, causing breakage of the glued fiberglass laminate structure. On Oct. 24 Quebec news station Radio-Gaspésie and newspaper Gaspésie Nouvelles reported about 20 persons had been laid off or suspended from their jobs at LM Wind Power, including “directors, managers and supervisors,” the newspaper report said.
Vineyard Wind and GE Vernova have been removing and replacing blades on turbines, with little information released on the work progress. GE Vernova CEO Scott Strazik has said quality testing on manufactured blades have shown similar defects on less than 10 percent of suspect blades, or “low single digits.”
Strazik says the company is “proactively reinforcing some blades, either in the factory or in the field, to improve their quality and ensure their useful life.” The federal Bureau of Safety and Environmental Enforcement (BSEE) is continuing its investigation into the blade failure.
