Giant industrial wind turbines routinely shed their blades, collapse and/or burst into terrifying fireballs.
Contrary to their ‘super-safe’, ‘clean’, ‘green’ image, giant industrial wind turbines are the perfect incendiary device.
Around the world, hundreds have exploded into in palls of smoke and balls of flame – in the process – each one raining molten metal and over 1,000 litres of flaming gear oil and hydraulic fluid (see our post here) and burning plastic earthwards.
Then, adding to an air of excitement, there’s their habit of shedding and/or shredding their blades with particles and chunks thrown for miles.
As if that was not enough, there have been dozens of cases when the entire superstructure succumbs to gravity, with earth-shattering results.
When any of the above occurs, the wind power outfits concerned go into damage control with ludicrous claims that the event in question is “rare”; vague reassurances about no one actually being killed (this time); and equally vague reassurances about the event being under ‘thorough investigation’.
As we detail yet another round of turbine terror, see if you can spot the industry spin.
Storm breaks Enercon and Nordex wind turbine blades in Germany and France
22 October 2021
Rotor blades at Enercon E-138 EP3 turbines in Germany and France broke during a heavy autumn storm that hit Europe on Thursday and also damaged a third machine from Nordex.
A blade on an Enercon E-138 EP3 at a wind farm in southern German was severely damaged during ‘storm Ignatz’, but no one was injured in the incident.
All nine 4.2MW wind turbines of the same type have been halted as a precaution at the Nattheim wind farm near the town of Heidenheim in the state of Baden-Württemberg, the operator said.
The wind farm is owned by municipal utility Stadtwerke Heidenheim (with a 74.9% stake) and the Alterric joint-venture of Enercon parent, the Aloys Wobben Foundation, and German regional utility EWE.
The autumn storm Ignatz caused damage across much of western Germany on Thursday, halting train traffic temporarily in some regions and causing floods in the northern city of Hamburg.
Enercon experts are at the site to investigate the root cause of the accident, and will dismantle the broken blade as soon as weather conditions permit.
All three rotor blades will then be replaced with new ones within the next few weeks, while the blades at the other eight wind turbines will also be checked, the operator said.
The Nattheim wind farm was commissioned in June of this year.
French incident probed
Enercon told Recharge that during the same storm with gusts of more than 100km per hour, a rotor blade of the same turbine type at a wind farm in Auzey in western France has also been damaged.
No one was injured in the French incident either, and an investigation into the root cause has been started.
The storm also damaged a blade of a Nordex N117-2.4MW turbine at a wind farm in the western German near the town of Cochem in the state of Rhineland-Palatinate, police said.
“A rotor blade of a wind turbine in the Zilshausen district was torn off by the storm and broke into innumerable pieces,” a police report said.
“A debris field was created within a radius of approx. 150 meters from the wind turbine. No damage to property or personal injury from the flying parts was recorded.
Nordex confirmed the incident and said its experts were investigating the root cause of the incident.
The damaged turbine had been maintained regularly, Nordex added.
The OEM last month had suffered the collapse of a turbine from its N149 model at a wind farm in western Germany for yet unknown reasons in what appears to be an unrelated event.
Wind turbine collapses overnight in Elk County
28 October 2021
A wind turbine has collapsed in Elk County.It happened sometime overnight at the Caney River Wind Farm. The Elk County Sheriff’s Office confirms to KAKE News that the turbine had previously been damaged, but finally collapsed sometime overnight as strong winds moved through the area.KAKE has reached out to the operator of the wind farm and are waiting for a response. Viewer Terry Till of Grenola sent these photos into KAKE.
Turbine Fire at The Netherlands’ Largest Offshore Wind Farm
28 October 2021
A year after commissioning the largest offshore wind farm in the Netherlands, and the second-largest operating offshore wind farm in the world, Ørsted is reporting that a fire damaged one of the wind turbines. The turbine malfunctioned the company reports causing the fire. A total of three turbines are now offline out of a total of 94 with the remainder of the farm continuing to operate.
“No employees were present when the fire broke out and no one was injured,” Ørsted said in a brief statement about the incident. The energy company that developed the site approximately 15 miles off the Dutch coast reports that it is working with the wind turbine manufacturer Siemens Gamesa to investigate the cause of the failure.
The damaged wind turbine is being dismantled to possibly reuse some of its parts. They are also working on the two other turbines that were linked to the damaged unit to restore them to operations. An inspection shows that they did not suffer any damage during the incident and appear to be able to operate normally.
Ørsted completed the commissioning of the Borssele 1 & 2 offshore wind farm in November 2020. The wind farm has a capacity of 752 MW, using Siemens Gamesa 8 MW turbines. The turbines are on monopiles in a water depth ranging between 45 and 115 feet of water.
Fires from the failures of the turbines happen periodically most often due to machinery failure. A report in Windpower Engineering and Turbine said that they had been 379 fires reported over the last 20 years. Experts believe the actual number is higher with incidents going unreported due to fears that it would damage the reputation of the industry.
