A 100-foot tower supporting a wind turbine at Salty Brine State Beach in Narragansett collapsed during a nor'easter, Tuesday.
This 100-foot turbine sited in Narragansett collapsed in winds over 50 miles per hour.
One of the five General Electric 6MW Haliade turbines installed at Deepwater Wind’s Block Island offshore project is reportedly down for repairs, potentially delaying the wind farm’s full commissioning.
The two barges became separated and drifted apart from each other in Block Island Sound before personnel secured the barge. One barge containing two of the 56-foot tall yellow decks was seen battling high seas off the island’s southwesterly side, while the other barge, carting three deck platforms, was situated off the coastline near the North Lighthouse.
Fugate says contractors with experience working in offshore energy projects in the Gulf of Mexico, have found the open waters of the Atlantic Ocean to be a more challenging work environment.
First, it was the weather. Rough seas forced the Providence company to push back until last Sunday the installation of the first steel foundation for the five-turbine wind farm off Block Island. Now, Deepwater is dealing with a construction mishap. Earlier this week, one of the barges being used in the project hit the latticework “jacket” foundation that had been placed in the water and dented one of its four hollow, tubular legs.
The 1.5-megawatt turbine was commissioned in March 2009 but was shut down June 18, 2012, after the gearbox showed significant wear. The faulty gearbox was no longer covered by warranty, and the manufacturer of the turbine, AAER Wind Energy of Quebec, is no longer in business. Three of five turbines of the same make and model erected in California and Templeton, Mass., also suffered gearbox failure.
"This is really important for people who are flying in bad weather to be able to land," said pilot Henry duPont, an island resident. Without the Sandy Point VOR, pilots without more advanced GPS technology would not be able to fly to Block Island legally, duPont said.
Gearbox reliability continues to dog the wind industry and as turbines become larger the push to improve performance becomes paramount.PORTSMOUTH - By a near-unanimous vote, the Town Council decided Oct. 23 to seek a public-private agreement to fix the town's broken wind turbine.
The company that installed the turbine, AAER of Canada, went bankrupt a year after installation, and left Portsmouth with no warranty. Even worse, the chief executive of the company hired to oversee maintenance of the turbine stated that gearbox failures occur in "10 percent of turbines nationwide".
For three years, the $3-million windmill fulfilled that promise, making the town about $400,000 after maintenance and debt payments. ...the turbine's gearbox needs to be replaced for at least $460,000 -- completely erasing those three years of income.
At Monday night's meeting, the town council was informed that the gearbox in the 1.5 megawatt turbine has failed. Though the reason for the failure is unknown, oil samples show metal shavings inside the gearbox filter. The turbine has been shut down since June 18. Replacing the gearbox could cost about $400,000.
Town officials are working to undercover what broke last week on the Portsmouth wind turbine generator. The turbine, located at Portsmouth High School, stopped spinning last week after an error message appeared.
"Our first thought was that no sane spray pilot would get near one, so we immediately called Farmer's Spraying Service from the meeting and the owner told us not only would he not treat a field with one of the towers, but he also would not care to do the application, if the tower was in an adjacent field.
The unexpected ruling, which cannot be appealed, was announced by Town Administrator Bruce Keiser at an unscheduled Town Council meeting on Sept. 14. The councilors had set aside the evening for a Ft. Getty workshop, which was delayed until they finished their discussions on a response to the FAA ruling.
Forty pages of health and safety information surrounding the proposed wind turbine project in town may never have been created had it not been for some anxious residents. Ron Pitt, chairman for the health and safety subcommittee that researched and wrote the report, said interested and concerned residents, including members of the group Citizens Wind Watch, should be credited for pushing forward the process of learning more about wind turbines and the issues that surround them. ...Mr. Russo said the recent health and safety report spelled a certain end to the likelihood the turbine would be constructed at the high school.
A dozen opponents of the high school site were at the meeting to ask the committee to immediately declare the high school off limits, and they presented a 21-page report that, they contended, proves that the turbine would pose a physical danger and noise hazard to students. But committee members said they wanted to review the report and hear counter-arguments from the town's renewable energy committee, which has asserted that the device is safe. It has voted to give preference to the alternative site, which would be 1,000 feet from any house and have stronger winds.
When Portsmouth moved its proposed wind turbine site at the high school farther away from the town water tank, the Federal Aviation Administration raised a caution flag. Richard Talipsky, economic development committee chairman, said the town received a "notice of presumed hazard" from the FAA on Sunday that this new site could be in the flight path for Newport Airport. ...After talking to an FAA official about the notice, Mr. Talipsky said it seems to have been a technicality in response to the new application. Mr. Talipsky said he was told the FAA would have approved the original site at the high school, which is the direction that will now be taken.
The federal government has rejected a proposal to install a wind turbine at a high school in Portsmouth. The Federal Aviation Administration says the 213-foot-tall wind turbine proposed for Portsmouth High School would be too high. The FAA says the plan needs to be modified. The agency had earlier rejected a proposed turbine at Portsmouth Middle School. ...Voters last fall approved a $3 million bond to build a wind turbine at either the middle school or high school.
...as the reality of the largest proposed offshore wind plant in the world comes into sharper focus, it becomes clear that 130 massive wind machines spread across 24 square miles of the sound threaten not only marine life and wildlife but also public safety.
