The operator of the wind farm released this short statement yesterday (8/22/2024):
We are aware of a blade failure which occurred this morning on an installed turbine at Dogger Bank A offshore wind farm, which is currently under construction. In line with safety procedures, the surrounding marine area has been restricted and relevant authorities notified. No one was injured or in the vicinity at the time the damage was sustained.
We are working closely with the turbine manufacturer, GE Vernova, which has initiated an investigation into the cause of the incident.
Further updates will be issued in due course as more information becomes available.
As the above examples illustrate, turbine blade failures, like the Vineyard Wind incident near Nantucket, are not unique to GE Vernova. GE’s rivals, Siemens Gamesa and Vestas, have also experienced serious quality control issues.
Per ReviewEconomy (2023), “Unexpected and increasing wind turbine failure rates, largely in newer and bigger models, are savaging the profits of some of the world’s biggest manufacturers, as Siemens Gamesa, GE and Vestas report heavy repair and maintenance losses.”
In light of the manufacturing challenges, all 3 companies report increased emphasis on quality control. Why has quality control to date been inadequate and how will the past problems be corrected?
Has the wind industry’s sense of entitlement, as evidenced in their tax credit, rate increase, and departure expectations, affected their safety and quality culture? Has industry and governmental wind energy promotion rushed development and compromised design and fabrication decisions? It’s time for wind developers, manufacturers, and regulators to make sure their priorities are in order.
… for their coverage of the Vineyard Wind turbine blade incident and their investigative reporting. From a recent Current article (emphasis added):
“The technology may not be new, but the size and scale of the Haliade-X turbine is novel for the offshore wind industry. And these jumbo-sized turbines have only recently been installed in just two locations in the world within the last year – at Vineyard Wind off Nantucket, and the Dogger Bank Wind Farm off the northeast coast of England. The Haliade-X turbine blades – which are supposed to have at least a 25-year lifespan – have suffered failures in both locations.“
“At the Dogger Bank Wind Farm – which is being completed in three sections which combined will make up the largest offshore wind farm in the world – the first GE Vernova Haliade-X turbine was installed in the fall of 2023 and began producing power on Oct. 10. But little is known about the blade failure that occurred just months later during the first week of May 2024. The damaged blade was disclosed by Dogger Bank’s owners – SSE Renewables, Equinor, and Vårgrønn – a week after the incident. In a statement, the companies said only that “damage was sustained to a single blade on an installed turbine at Dogger Bank A offshore wind farm.”
“One reason the turbine blade incident at the Dogger Bank may not have generated more attention at the time is that the wind farm is located 100 miles off the coast of England, rather than just the 15 miles in the case of Vineyard Wind and Nantucket. If any debris was generated, it would have a far wider area to disperse in before nearing land – if it made it that far at all.“
Interestingly per the Current:
The Haliade-X turbine is the same one Orsted – a partner in Vineyard Wind – is planning to use for offshore wind farms slated for the waters off New Jersey and Maryland.
Land-based turbines have come apart in Sweden, Germany, Lithuania, Cypress, Brazil, and the US (and presumably elsewhere).
Greater transparency regarding turbine incidents, both in the US and internationally, is clearly needed. As we have learned from decades of experience with the oil and gas industry, most companies prefer reporting systems (if any) that protect details and information about the responsible parties from public disclosure. It’s the responsibility of the regulators to make sure that incident data and investigation reports are timely, complete, and publicly available. This is made more difficult by the promotional role that government agencies have assumed for offshore wind.
GE Vernova’s SEC filing for the second quarter of 2024 is attached. The Vineyard Wind turbine blade incident, the main reason for the sharp decline in their stock value in mid-July, is described as follows:
VINEYARD WIND OFFSHORE WIND FARM. We are the manufacturer and supplier of turbines and blades and the installation contractor for Vineyard Wind 1 offshore wind farm in the Atlantic Ocean (Vineyard Wind), at which we have installed 24 of 62 Haliade-X 220m wind turbines to date. Subsequent to the period covered by this report, a wind turbine blade event occurred at Vineyard Wind. Debris from the blade was released into the Atlantic Ocean and some has washed ashore on nearby beaches. On July 15, 2024, the U.S. Bureau of Safety and Environmental Enforcement (BSEE) issued a suspension order to cease power production and the installation of new wind turbines at the project site, pending an investigation of the event. As of the date of the filing of this report, we are currently engaged in a root cause analysis of the incident. We do not have an indication as to when BSEE will modify or lift its suspension order. Under our contractual arrangement with the developer of Vineyard Wind, we may receive claims for damages, including liquidated damages for delayed completion, and other incremental or remedial costs. These amounts could be significant and adversely affect our cash collection timelines and contract profitability. We are currently unable to reasonably estimate what impact the event, any potential claims, or the related BSEE order would have on our financial position, results of operations and cash flows
“Within only two to three years of commercial operation, the GE wind turbine generators have exhibited numerous material defects on major components and experienced several complete failures, at least one turbine blade liberation event, and other deficiencies,” alleged AEP.
“While we continue to work to finalize our root cause analysis, our investigation to date indicates that the affected blade experienced a manufacturing deviation,” said GE Vernova CEO Scott Strazik. “We have not identified information indicating an engineering design flaw in the blade or information of a connection with the blade event we experienced at an offshore wind project in the UK, which was caused by an installation error out at sea. We are working with urgency to scrutinize our operations across offshore wind. Pace matters here. But we are going to be thorough, instead of rushed.”
“It’s been 11 days since the event, and just to reinforce from the start, we have no indications of an engineering design flaw,” Strazik said. “We have identified a material deviation or a manufacturing deviation in one of our factories that, through the inspection or quality assurance process, we should have identified. Because of that, we’re going to use our existing data and reinspect all of the blades we’ve made for offshore wind. For context, this factory in Gaspé, Canada where the material deviation existed we’ve made about 150 blades.
Any comments from the CVA, assuming there was one?
Meanwhile, Nantucket will renegotiate their “Good Neighbor Agreement” with Vineyard Wind. Is this a lesson for other municipalities?
🚨 Nantucket Select Board chair Brooke Mohr just announced that the town intends to renegotiate the terms of the Good Neighbor Agreement with Vineyard Wind.
