Library filed under Structural Failure from Massachusetts
The Massachusetts Water Resources Authority's wind turbine at the DeLauri Sewer Pump Station will be shut down in the coming weeks as a concrete ring and new piles are installed around the existing foundation. Workers performing a routine inspection of the turbine in February found that its foundation settled faster than expected, according to the authority.
After the crack was analyzed, replacing the blade was considered, but last Wednesday Hyundai engineers decided to remove a section of the blade and replace it with new material, Ruiz said.
The Massachusetts Water Resource Authority has reiterated its claim that the Charlestown wind turbine with its floating foundation that has been sinking remains safe and has been constructed with a safety factor twice that of which is required.
The Massachusetts Water Resource Authority’s new wind turbine in Charlestown has apparently sunk about 2 inches causing significant worry that the structural integrity of the 426,000 pound turbine is at risk.
Massachusetts Water Resources Authority honchos and engineers met yesterday to figure out a fix for the $4.7 million wind turbine, which started turning in October, only to power down last month when crews discovered it had settled about 2 inches, agency officials said. Possible causes, they said, include soil conditions and vibrations from a sudden shutdown triggered by high winds.
Two of the three blades on the 15,000 Kw wind turbine at Peck's Boats in Marstons Mills broke off in high-gusting winds early Sunday morning. It was a bad day for windmills in Marstons Mills. At Peck's Boats, two of the three blades of its 15,000 Kw turbine broke from the 100-foot tall installation.
Two blades of a wind turbine were blown off during the strong nor’easter ravaging Cape Cod. According to spectators near the scene, two blades atop the approximately 60 foot wind turbine blew off around noon. A section of the blades could be seen on the ground approximately 100 feet from the wind turbine. Editor's note: According to news reports, the Aircon-10 turbine was erected in May 2009. It has a capacity of 10 kilowatts and stands 100-feet tall from base to blade tip.
Around 12 p.m. Sunday, two blades of a wind turbine were reportedly blown off during the strong nor’easter ravaging Cape Cod. According to spectators near the scene, two blades atop the approximately 60 foot wind turbine blew off around noon.
A portion of one of the blades on the Bartlett's Ocean View Farm windmill broke off at some point Sunday night and plummeted to the ground below.
Early Monday morning, a 20-foot-plus piece of one of the blades on Bartlett's Ocean View Farm's wind turbine snapped off and fell to the ground nearby. The wind turbine immediately shut down. There were no reported injuries when the blade struck the surrounding farmland, said John Bartlett.
DARTMOUTH - One of the many casualties of this weekend's storm was a windmill installed by former state Rep. Mark A. Howland. Arthur Larrivee paid Mr. Howland $16,000 for a windmill and solar panel system for his home at 620 Tucker Road and received everything he asked for: two windmills atop 35-foot-high poles, four solar panels and electrical equipment to convert the power generated into electricity. But on Monday morning, he woke to find that the steel poles of one windmill had snapped clean off about 4 feet above the ground, leaving the windmill lying on the ground. "I honestly couldn't believe it," said Mr. Larrivee, a real estate broker and Republican activist. "It had to be a flaw in the piping."
The top half of one of the 100-foot windmills, with its broken turbine and missing blades, lies on the ground at the Princeton Municipal Light Departmentwind site.
PRINCETON — On February 21, when Princeton Light Department Manager Jonathan Fitch drove over Westminster Road to check on the windmills, he got an unpleasant surprise.
"Today, the task before the Joint Committee (regarding Bill S40) is to hear from the public on what would appear simple - the giving and taking of “driveway” easements between the Commonwealth’s Wachusett Reservation (Stagecoach Trail) and the Town of Princeton’s legal “right of way” for its wind power site. As well, the town is offering the to transfer to the Commonwealth, ownership of, five acres of their 16-acre wind site. I urge the Joint Committee for Bill S40 to carefully consider the following with regard to your recommendations an for easement exchange and accession of land from Princeton: 1. The Wachusett Wind Site is a 16 acre parcel wholly surrounded by the Wachusett Reservation and flanked within few feet, on three sides, by the well traveled Midstate, Harrington and Stagecoach trails. This portion of the state park is accessible and popular. 2. The present eight windmills are 120-feet high and are proposed to be replaced with two windmills as high as a 35- story building and with blades that stretch as wide as a football field - windmills whose elevation will come with 150- feet of the mountain’s elevation. 3. In the wintertime Wachusett experiences unusual ice storms in number and severity 4. In the wintertime, the windmills accumulate ice - then release it when it melts and falls, when it is blown off by wind or is thrown it off by the rotating blades 5. This ice has put holes in the roofs of utilty buildings on the wind farm and scattters itself across the fully accesssible wind site, the state reservation and hiking trails, threatening state park viisitors The risk associated with being struck windmill ice can be quantified and is relative to one’s distance from the windmills and will increase geometrically with the proposed windmills. 6. Windmills and wind data collection towers at Wachusett have structurally failed five times in twenty years on the Town of Princeton (PMLD) site. This also threatens the state park visitors as well with collapsing metal structures and flying blades. Proposed windmills and data towers will not be installed in compliance withthe manufacuturer’s recommendations and safety warnings."......
