Library filed under Structural Failure from Michigan
“The cause for the blade breaking was a carbon failure at the 19-meter mark that was not formed properly,” Buda said. “Failure in the heating oven at the plant caused the blade to break later on.” ...properly made wind turbines can handle wind speeds up to 125 mph.
Unsure of what to do with its broken turbine, Union Township officials have tabled making a decision until the township consults with Central Michigan University. The north Skystream, a $16,634 grant-funded wind turbine installed for research purposes, no longer works, and the city is not sure why.
An oil leak at the Heritage Garden Wind Farm in Garden caused an uproar recently. The oil leaked was a spray from a cell under one of the turbines. Heritage Garden Wind Farm.
It took four months after the initial breakdown to find and obtain a part from Europe at a cost of almost $38,000. Workers installed the new part on Jan. 4, but it failed two days later. The supplier eventually replaced it after another lengthy search. The part was installed April 16. It lasted three days.
Scott L. Simons, DTE Energy spokesman, previously told the Tribune that the utility received an alarm at 1 a.m., and later found that one of the blades at the Sigel site appeared to be damaged. Part of a blade had fallen and was on the ground. ...Last year, two GE-manufactured turbines experienced broken blades in East Central Illinois.
Officials said Friday that there isn't any new information indicating why a wind turbine blade broke off early Monday morning during a low-wind period at DTE Energy's Thumb Wind Park. ...Last year, two GE-manufactured turbines experienced broken blades in East Central Illinois.
DTE Energy has no idea why a portion of a wind turbine blade broke off early Monday morning during a low-wind period at one of the utility's sites in the Thumb Wind Park. "This matter certainly is under investigation," said Scott L. Simons, DTE Energy spokesman.
One of DTE Energy's wind turbines in Sigel Township is motionless after one of the blades on the structure failed during low wind conditions. Pieces of the blade were lying on the ground near the tower. No details as to the cause of the break were available.
A wind turbine on South Stiles Road may have been struck by lightning in the storm about 8 Saturday night. It continues to operate and officials called to the scene, between Kinney and Chauvez roads, have since cleared the area.
Nearly sixth months have gone by since the $250,000 wind turbine produced any electricity. ...They would have the turbine's original manufacturer, Canada-based Entegrity Wind Systems, repair the system, but the company filed for bankruptcy in late 2009, months after installing the unit. "It's kind of annoying ...We had a 20-year maintenance agreement with them, all for naught."
According to Kevin King, chief of field operations and facilities section for all DEQ offices across the state, the turbine may have a gear box failure. The DEQ hired the turbine's original manufacturer to climb the tower and take a peek to see what was wrong, but that proved to be unsuccessful.
Construction crews will have to assess the damage to a wind turbine that caught fire in Missaukee County.
Smith said brief power outages experienced in the area cause the three turbines to instantly stop and recoil, which fatigues the blades in the area where they are likely to break. When the blades are new, they're more flexible and durable. ...we are going to direct all maintenance employees to approach away from the blades and keep visitors away. The blade ejection happens rarely, but we need to err on the side of safety.
