Foundations Of 1000 Offshore Wind Turbines Crumbling

The foundations of some 1000 offshore wind turbines are crumbling. Danish companies face law suits over the liability and the yet unknown bills for repairs. A large brawl in the wind industry is underway. Serious design flaws in the foundations of some 1000 offshore wind turbines are now leading to lawsuits against and financial losses of several Danish companies. However, there is no overview of the problem, its economic scale and who will have to foot the bill.

Hundreds of Britain’s offshore wind turbines could be sinking into the sea because of a design flaw.

It is believed the concrete used to fix some turbines to their steel foundation can wear away, causing the power generators to drop a few inches.

The fault was first discovered at the Egmond aan Zee wind farm in the Netherlands and affects those with single cylinder foundations.

Energy company engineers are now urgently investigating what extent the turbines have been destabilised. If repairs are necessary then turbines will be shut down one at a time to prevent energy losses.

Experts from Renewables UK, which represents wind farm developers, said it could cost £50million to fix Britain’s 336 turbines thought to be at risk.
