July 22, 2024 — The 300-foot blade section that detached from a Vineyard Wind turbine this week sank to the ocean floor, Nantucket officials said Friday. Nautical charts show waters are about 150 feet deep in the area (or roughly half as deep as the blade is long).
Meanwhile, a federal official said they have no time estimate on when the project shutdown might end because the investigation is in its early stages. While officials try to determine the cause of the blade failure, turbine components will continue to arrive at the New Bedford staging terminal, but won’t be heading back out to sea for installation.
Vineyard Wind and GE Vernova have not shared their plans for retrieving the major blade piece as of Friday afternoon. About half of the fiberglass shell remains attached to the nacelle, and most of the foam core was released during the initial failure on July 13, according to Nantucket officials.
Amid concerns about health and economic impacts, town officials said Vineyard Wind is developing a water quality testing plan for the island and setting up a process in which affected people can file claims.
“Vineyard Wind is fully responsible for the repercussions on Nantucket, and Town Administration and the Select Board will ensure they are held accountable,” said the town in a statement Friday. Per a meeting agenda filed the same day, the Select Board and county commissioners are scheduled to meet next week to discuss possible litigation against the company over the incident.
Also on Friday, BSEE and Vineyard Wind representatives delivered limited updates during a previously scheduled meeting of state officials and fishing industry members. The group meets regularly to discuss offshore wind developments; the turbine incident was added to the top of the agenda and discussed for just under an hour.
