Hurrah for the wind

They noted that “wind speeds are part of our root-cause investigation”.

What! We get strong winds in the UK? Why did no one tell us this!

Ban wind, ban it now, for the sake of the Wind Turbines!

Nothing can be replied upon to work outside of its specifications.

The £250,000 tower, which stood as tall as a six storey building, was hit by gale force gusts of 50mph.
This giant structure was ripped from it's anchors after a puff of wind of a mere 50mph??

I take it they used several tubes of 'No More Nails' to keep it in place rather than actually going to the bother of bolting the thing to the base..........?

Since it's really just a money transference (from poor to rich) machine, why would bolts be required?

"Well done Denzell, that seems to have done the trick, just pop that big spanner in the back of my spaceship!"

"Thank ee kindly your mongship, but what if them there city folks rebuild it?"

"Ah Denzell, by then you'll have your own spanner!"

"Rooiiight you are there your monnnngness!"

Strange, in the photo there's no deformation at all around the base of the tower as one would expect, I'd have thought you'd have seen signs of bending caused by wind shearing bolts on one side first, as is usual with wind damage.

This appears to be a one off as plenty turbines up here routinely surviving much higher wind speeds.

That tubular structure is extremely strong, but if it's not correctly torqued down they can start to rock slightly in the wind, hardly noticable but with incredible force due to the leverage of the high tower. The studs in the base ring then have only two choices open, snap or strip threads!

The firm who put it up were probably Irish pikeys in an old white transit van, the one with the Guiness label tax disc.

The nimbys are out in force speculating and making up any kind of crap in that article.

I know but most incidents of damage I've seen haven't involved an entire tower collapse.

Quite unusual, shoddy workmanship as you suggest

They'll be looking for a new site, your road/street/garden?

Not as much fun as this one though.

I don't know, they seem to be handy if you need to start a fire to keep warm :)

I can do speculation. Undersized bolts and oversized washers. Or underlength bolts and insufficient thread engagement. Or lack of torque wrench, pipe wrench and scaffold tube instead. Or Screwfix only had Grade 4.6 nuts, fit them with the markings against the plate, nobody'll know. Or it's getting late, we'll tighten them tomorrow.

I've seen every combination in steel-framed buildings and bridges. My favourite was when the holes didn't align so the bolt heads were cut off and stuck on with mastic.

Ye gods man, since when has 50Mph been a strong wind? We had 52Kt (62Mph)sustained all day yesterday and winds of up to 82Kt (94Mph) the night before, with the mean being about 60Kt. No real damage with the turbines here although one shed and further North a house went. Methinks its shoddy workmanship.

Re speculation.

Another good one is where someone drills through the fixing holes into the concrete, squirts resin into the hole and drops the bolt into it. Useless as a fixing but undetectable and resists checking with a torque wrench.

Or the anchor studs don't align with the holes in the base plate so are hammered into position. That's good for weakening the studs. The alternative is that the holes in the base plate are widened, ultimately allowing the washers to pull though.

Still, at least it fell over now while it's still in warranty and the installers are still around rather than in 10 years time due to corroded bolts when the installers have gone bust.
