“Unfortunately with the hazards because of the heavy machinery that's up there, there's not much that we could do until it falls down or wait until the point that it's safe and we can send somebody up there to make an inspection,” says Jay Deboer, the Deputy Chief for McBain Fire Department.
According to Minden City Fire Chief Zach Kramer, a blade snapped on the turbine sometime overnight Wednesday and it's hanging on, blowing debris across the area. The turbine is located right next to Sanilac County's snowmobile Trail No. 20, which is the main trail between Minden City and Deckerville.
A broken wind turbine off of Minden and Ridley roads has officials asking snowmobilers in the area to steer clear of a popular trail near the damaged turbine.
Three Ocotillo residents went before the Board of Supervisors Tuesday.
Siemens conducted a “preliminary root cause analysis,” which showed that the machine had “cracks in the structural member of the interior of the blade” (specifically, the shear web). In turn, over time, the blade failed and then struck the tower, which then collapsed.
Fifty blades in the Deerfield Wind Energy Project were discovered to have the same issue as the two that broke and dangled from their towers near the intersection of Redman and Iseler roads ...Lack of adhesive was discovered to be the problem, and the defective blades are being repaired, said Jason Sterling, site construction manager of Vestas.
Both this project and Siemens have a history of serious problems, however, leading to questions of whether federal or state oversight is needed to protect public safety. Ocotillo Wind, built by Pattern Energy, previously had a wind turbine fire in January 2015 and an 11-ton blade hurled off onto a public trail in May 2013, among other mechanical failures, as we reported at the time.
The wind turbine in Bear Creek Township caught fire Thursday afternoon. ...Smoke from the fire could be seen for miles.
Shortly after the firefighters arrived, Roye said, one of the burning blades broke loose and fell to the ground, causing a pendulum motion where the wind turbine began to sway back and forth. A second burning blade then broke loose and fell to the ground.
“Faced with this increased scrutiny [from negative headlines] and the long-term financial impact of a total turbine loss, we need to address the causes and consequences of turbine fires and, as a community, recognise that it affects each company in the industry. “We cannot allow a handful of torched assets to become a symbol of our inability to work together.”
The Technology and Construction Court in London has ruled that cracking discovered on some of the 140 monopiles built by Shanghai Zhenhua Heavy Industries Ltd (ZPMC) for the Greater Gabbard offshore wind farm ”was largely a result of various failures by ZPMC to maintain correct preheat temperature of the welds to the monopiles.”
A single blade on two different wind turbines at wind farms bounded by Verona, Redman, Huron City and Kinde Roads were hanging by a literal thread this morning after having apparently snapped in half.
An investigation is under way following a crane collapse at NextEra Energy Resources LLC’s 200 MW Osborn Wind Energy Center, currently being built in Missouri. ...a three-blade rotor on one of the turbines fell down and sustained damage.
The company says that on Sunday, Oct. 2., the nacelle, hub and blades on a Siemens 3.0 MW direct-drive wind turbine inexplicably separated from the tower and fell to the ground.
The blades, hub and nacelle of one of eight Auwahi Wind turbines in the Kanaio area separated from the tower and fell to the ground Sunday, an official with the wind-power generation company said Monday.
The flames struck this morning in Isselburg in North Rhine-Westphalia. Emergency services were called at 6am to the turbine near Wolf Lake. Around 40 emergency personnel and six vehicles attended the scene. Investigators looking into possibility that a lightning storm was to blame.
Wednesday afternoon, flat-bed trucks were seen entering the wind farm to retrieve shipping containers used to transport equipment and tools to the site. There is no timeline for when the investigation will be complete.
Two investigations has been launched into the collapse of an 80-metre wind turbine in Cape Breton, believed to be the first catastrophic failure of its kind in Canada.
One week after an 80-metre wind turbine collapsed in Cape Breton, there is still no clear indication of what caused what's believed to be the first catastrophic failure of its kind in Canada.
Enercon said the incident occurred on 17 August during a "scheduled component exchange".
