Structural Failure and Europe
An Austrian wind farm had to be closed after a blade snapped off one of the wind turbines, and fell over 100 metres to the ground.
According to Austrian power the reason was a production fault and not because of a lightning strike as had previously been feared.
Only shortly after tackling a nacelle fire on one of its V112-3.0MW turbines in Germany in April, the Danish manufacturer has had to contend with another fire, this time on one of its V90-2MW machine in Spain.
The incident took place early Friday morning. While the winds were strong, they were within the operational limits of the machine.
Repower and EDF Energies Nouvelles (EDF EN), which owns the plant, are carrying out an investigation to find the cause of the accident.
OFFSHORE: Siemens is carrying out essential maintenance work on four offshore wind farms, including the recently opened Gunfleet Sands, after it was discovered the turbines' bearings were corroding.
Wiese says that Areva Wind and Renk will bear the full cost of replacing the broken gearboxes. "We have an interest in seeing all six exchanged, because obviously the gearboxes are the exact same in all of them."
Germany's first offshore wind park was dealt a blow with the failure of two turbines due to inferior materials. The rough patch has energy executives scurrying to reassure Berlin and banks scrutinizing their billions in offshore wind energy investments.
Hundreds of European offshore wind turbines have a design fault which allows them to move and slide on their bases. Turbine manufacturers and wind farm operators believe that finding a solution could take months and cost into the millions of pounds.
Hundreds of offshore wind turbines could be suffering from a design flaw that makes them sink into the sea.
Energy company engineers are urgently investigating the extent to which their offshore wind farms are affected, after flaws were discovered on a Dutch wind farm last autumn.
The problem could cost £50 million, said Renewables UK, the industry body that represents wind farm developers.
Hundreds of Britain's offshore wind turbines may have a design flaw that makes them SINK, The Sun can reveal.
Concrete in their foundations can wear away - leaving the power generators to drop several centimetres into the seabed and become less stable.
The problem is in the grouting used at the top of the monopile, where a "transition piece" slides over it. This supports the tower by holding the monopole foundations in place and is beginning to fail as a result of the high stress levels imposed by the turbine. Investigations revealed the foundations at a number of offshore wind farms have shifted.
Officials at ReDriven Power Inc. are confident of their young company's continued success, but concede they've recently issued a recall on the blades of 10 turbines installed in the U.S. ..."We did have a blade problem," said president and CEO Joseph Ianni, when The AgriNews paid a visit to the firm's headquarters inside a former textile mill recently.
Wind power may be one of the cleaner, greener energy sources available, but turbine and blade failures point to dangers that were not anticipated, says Michael Connellan
In what implies a Rs.1 billion ($25 million) hit on its balance sheet for the current quarter, leading wind power equipment-maker Suzlon Energy will refit wind turbine blades for a project in the US, the company said Monday. “The company will do a retrofit programme to resolve blade-cracking issues discovered during the operations of some of its S88 turbines in the US,” the company informed the Bombay Stock Exchange Monday.
