Wind Turbine Collapse in New Brunswick (CAN)
Wind Turbine Collapse in New Brunswick (CAN)
(OP)
By the sounds of the CBC article, it appears this would be considered an engineering failure, multiplied 50x.

Enlarging the photo of the base hints at what I would expect if the anchor bolts pulled out of the concrete. Better post accident pictures would be nice
The following drawing looks somewhat like the pictures.
This is one of the situations where the cost of not fulfilling contract obligations related to delivering power could be larger than the large cost of replacing the foundations.https://thedeepdive.ca/transalta-renewables-forced...

Is there only one set of top bars crossing the failure plane?
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

The base of the anchor bolts for the turbine seem to finish above the level of the bottom bars.

I've never liked the the double bolt circle arrangement. Usually the larger circle resists a greater amount of tension than the inner circle but I have seen pole designers take the average diameter for the section modulus.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

"The company says the discovery of the subsurface cracks means the foundations will likely need repairs, and if replacement is required, costs are estimated at $1.5 million to $2 million per foundation.
The suspended operation includes 50 wind turbines at Kent Hills 1 and Kent Hills 2, where the tower collapsed. Five turbines at Kent Hills 3 continue to operate."

One of the pre-construction photos, above, appears to show cracks... could be thermal from mass concrete. The references to foundation failure come from the provider of the wind turbine, so I'm not convinced yet. They are the ones making the claims about the foundation failing. It's strange that no one has taken photos of the actual failure surface. If I were on site this would be my main interest... also to see what damage was done the the wind turbine itself.

It's always funny (to me) when a third world country makes that kind of achievement. That and $2.00 will get you a cup of coffee in these environments.
