Ørsted has launched an investigation after one of the turbines and its foundation at the 165.6MW Nysted (Rødsand 1) offshore wind farm tilted. The Siemens Gamesa SWT-2.3-82 turbine tilted late on Wednesday (12 January) afternoon, the Danish developer confirmed.
Asked how a crack in a blade on the windmill could cause the main tower to collapse, as occurred on Sept. 16, Matt Dallas, a spokesman for wind farm parent firm Pattern Energy, explained Tuesday, “The crack propagated over time, causing the blade to detach, which in turn led to the turbine collapse.” After the incident, the federal Bureau of Land Management ordered the facility’s 112 windmills shut down while Pattern investigated the cause and developed a plan to prevent further such incidents.
An investigation into what caused the collapse of a wind turbine at New Brunswick's largest wind farm has revealed serious structural issues that affect not only the turbine that fell, but dozens of others in the area as well. According to TransAlta Renewables Inc., the Alberta-based company that owns and operates the Kent Hills wind farm, the cracks formed because of "deficiencies in the original design of the foundations."
TransAlta Renewables Inc. said replacing 50 foundations will cost C$75 million to C$100 million (US$59 million to $79 million) and take until the end of 2023. The Calgary-based company expects to lose C$3.4 million per month in revenue while the turbines are off line, according to a statement Tuesday.
Based on initial estimates, TransAlta says the replacement of the foundations at its Kent Hills 1 and 2 wind sites is expected to cost between $75-million and $100-million. It also estimates it will result in foregone revenue of about $3.4-million per month on an annualized basis for so long as all 50 wind turbines are off-line, based on average historical wind production.
A wind turbine in Kingfisher County caught fire on Saturday afternoon. At 12:46 p.m., a fire was reported in the nacelle of a wind turbine at the Kingfisher Wind project in Kingfisher County.
The community wind farm’s two GE 5.3-158 turbines were commissioned in 2021. A GE spokesman would not confirm the condition of the other turbine at the site.
A fire in a wind turbine in a wind farm near the municipality of Sarow (Mecklenburg Lake District) near Demmin resulted in damage of around 500,000 euros. As a police spokesman said on Tuesday, the machine house in the uppermost part of the wind turbine caught fire in strong winds. Because of the height of around 100 meters, the fire fighters were only able to "let the fire burn down in a controlled manner" late on Monday evening, as the district brigade leader Enrico Kollhof explained.
Vegard Knudsen, communications consultant at Trønderenergi, tells E24 that they have now stopped all production, taken out all staff and closed to traffic in the park. We are sending in the necessary crew to examine all the wind blades now, he says. The wind facility consists of 14 Vestas V136/4.0-4.2 MW turbines each with a rotor diameter of 136 meters (446 feet). The facility was placed in service on October 1, 2020. According to company information the project was opened to the public on January 1, 2021.
TransAlta Renewables Inc. lowered its financial guidance for this year as it said it has found cracks in several foundations of the turbines at a wind farm in New Brunswick where a tower collapsed earlier this month.
TransAlta Renewables Inc. says it has found cracks in several foundations of the turbines at a wind farm in New Brunswick where a tower collapsed in September. The company says the discovery of the subsurface cracks means the foundations will likely need repairs, and if replacement is required, costs are estimated at $1.5 million to $2 million per foundation.
A wind turbine has collapsed in Elk County. It happened sometime overnight at the Caney River Wind Farm. The facility was placed in service in 2012.
The components – weighing a combined 126 tonnes – fell from lifting equipment during planned maintenance work, the developer stated. Some of the turbine components have broken up and debris has come ashore.
Debris from an offshore wind farm caused by a "disappointing" maintenance work error could be widespread, an operator has warned.
On 21 October, the storm, named Ignatz, hit with gale-force gusts of wind at speeds of more than 100km/h causing rotor blade damage to two E-138 EP3 turbines, an Enercon spokesperson said.
The "Ignatz" storm caused numerous problems in many regions. More than 60 incidents reported to the Aalen police headquarters - mostly from the Rems-Murr district.
A hub, three 61-metre blades, and blade clamping tool have fallen into the sea during major component exchange at the Ormonde offshore wind farm in the UK, with majority of the parts and tools now resting on the seabed and debris from one broken blade reported to be on the sea surface.
"The cause of the incident is under investigation," TransAlta spokesperson James Mottershead said in an email to CBC News. The area surrounding the wind facility has been closed while the investigation is underway. ...According to the company's website, the Kent Hills wind farm is the largest wind facility in the province, with more than 50 wind turbines.
According to a statement on RAG Montan Immobilien’s website “The plant has completely collapsed, most of the components such as the wings, machine house and the upper steel element are at the base of the plant and in the adjacent forest.” According to local news reports, the incident could be heard several kilometres away.
According to Nordex, there are almost two dozen identical turbines in Germany or are still under construction. As a preventive measure, all 23 systems with the same configuration have been temporarily shut down nationwide, according to Nordex. This also includes a neighboring facility in Haltern. Among other things, the identical Jüchen wind farm was taken off the grid.
