Vineyard Wind has resumed turbine blade installation on its offshore wind farm, marking the first such activity since a blade broke off earlier this year. Vineyard Wind and government officials confirmed that the work commenced on Saturday, and three blades were successfully installed over the weekend.
The resumption follows a five-month hiatus after a catastrophic blade failure in July scattered thousands of debris pieces into the ocean. The development signifies a critical step forward for the 62-turbine wind farm located 14 miles south of Martha’s Vineyard.
The Bureau of Safety and Environmental Enforcement (BSEE), investigating the blade failure, approved the resumption of blade work in October under strict safety protocols. In a statement released Monday, Vineyard Wind acknowledged that the construction followed extensive inspections and optimization of monitoring technology.
“Following a rigorous process including both extensive inspection and optimization of new monitoring technology, an initial set of blades has fulfilled the conditions for installation,” said Craig Gilvarg, a spokesperson for Vineyard Wind.
The approval process involved detailed data submissions, engineering evaluations by GE Vernova, the turbine manufacturer, and third-party verification. According to BSEE, installation is being approached incrementally to ensure safety and prevent future incidents.
The blade failure in July prompted Vineyard Wind and GE Vernova to conduct a root-cause analysis while BSEE launched its investigation. GE Vernova attributed the failure to a manufacturing deviation not detected during inspections. Subsequently, Vineyard Wind had to return additional blades that were suspected of having similar defects.
Each turbine in the farm features three blades, each 107 meters long, attached to a nacelle that sits atop an 837-foot tower. These massive structures represent some of the most advanced offshore wind technology, but the July failure underscored the challenges of scaling such innovations.
Nantucket officials, who closely monitor offshore wind developments south of the island, alerted residents about the resumed construction late last week. Community engagement remains a priority as the project progresses amid heightened scrutiny.
The offshore wind farm’s planned capacity of 62 turbines aims to deliver 136 megawatts of power to the New England grid. Before the blade failure, Vineyard Wind held the title of the largest operational offshore wind project in the United States, a status it aims to reclaim as installations continue.
While BSEE had previously restricted Vineyard Wind’s activities to cable-laying and tower erection, this latest approval for blade installations signals a turning point. However, the agency has emphasized that further installations will be evaluated on a case-by-case basis to ensure compliance with safety standards.
The project’s trajectory highlights the complexities of offshore wind development and the necessity for robust quality assurance and community transparency.
In related news, GE Vernova Inc., in collaboration with Drydocks World, announced its selection for the Ostwind 4 project by 50Hertz, a leading German Transmission System Operator (TSO). The project entails designing, constructing, and commissioning a 2-gigawatt (GW) High-Voltage Direct Current (HVDC) electric transmission system—the first in the German Baltic Sea—connecting an offshore wind farm to the German grid.
Located in the Arkona Basin, approximately 30 kilometers northeast of Rügen Island, the Ostwind 4 project will transport up to 2 GW of offshore wind energy to the mainland, providing renewable electricity sufficient to power nearly two million households. Scheduled for completion by the end of 2031, the project features an advanced bipolar HVDC transmission system operating at 525 kilovolts (kV), ensuring efficient energy transport with minimal losses over long distances.
Germany’s Energiewende framework sets ambitious renewable energy goals, including phasing out coal by 2030 and achieving net-zero emissions by 2045. Ostwind 4 is pivotal in achieving these targets by enabling efficient energy transmission from offshore wind farms to the national grid.
Stefan Kapferer, CEO of 50Hertz, stated, “The awarding of the contract to GE Vernova and Drydock World marks the beginning of a new chapter in the use of wind energy in the Baltic Sea. This pioneering work highlights the importance of cross-border collaboration and advanced technology in maximizing renewable energy potential.”
Philippe Piron, CEO of GE Vernova’s Electrification business, added, “Ostwind 4 represents a crucial milestone in our mission to electrify and decarbonize. By leveraging our advanced HVDC technology, this project underscores offshore wind’s essential role in accelerating the global energy transition.”
Deadline: December 20.
