Hundreds of European offshore wind turbines have a design flaw that is causing them to slide on their bases, Reuters reports. European turbine manufacturers and wind farm operators say the problem is occurring in towers that use grouting – a mixture of cement, sand and gravel – to attach the turbines to their bases.
This is an industry-wide problem and is not specific to one particular tower model, Reuters notes, and it is not expected to delay new projects or halt electricity production.
Several turbine manufacturers say they have made design changes as a result of this issue, but they agree that it has not affected power generation in any of the affected turbines.
