Dear Mr Bradshaw MP
I am sure you are aware another Wind Turbine collapsed a couple of days ago
in Northern Ireland. Apparently the WT collapsed in light winds.
Could it be these WTs are collapsing due to Vortex Induced Vibration
(VIV)? Please see the following article on this matter.
It’s probably a factor compounded further by too thin steel.
As we speak, I am sure the Health and Safety Executive has commenced a 12 month x £200K
investigation. Nice job if you can get one.
Yours sincerely
Alan M Dransfield
