Wind Turbine Collapse in New Brunswick (CAN) 1

[dik]

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.

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

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.

Those cracks are on the sides, not between the pole anchor rods and the tie-down rods. I also wouldn't be happy with those cracks.

Thanks old... but the photo is so poor that I cannot tell the condition at the top and the windmill supplier only talks about cracked foundations. I'd really like to see a close up photo.

These things always look funny to my eye. Too tall and skinny for their own good. I'm surprised there are not more issues with collapses.

Because there's not more failures, it means it nicely engineered... I really dislike PEMBs, but I do appreciated the engineering that goes into them... just like the old Volkswagons...

The rock anchored piles actually have pancake shaped voids on the top. So when the anchors are post tensioned the concrete cap and piles can be drawn tight and the anchor bond to the earth can be mobilized. They fill them with grout through tubes afterwards. You can see the tubes in one of the photos above. Pretty neat stuff.
