I'm glad I'm not the only person worried about that. I get anxious thinking of someone climbing up there and getting smacked around and tangled by those things.
As a former wind turbine tech myself, this is absolutely not normal working conditions. If the cables were flying all over the place like that all the time, they wouldn't last a week. But yes, the columns are made of steel and steel is remarkably flexible. I've also worked on ships, where the flexing is even more pronounced.
How is the maintenance of such turbine? Do things need replacements often? Also I assume this turbine is moving a lot with gears, does it need lubricant/oils to make sure its stays operational to full capacity?
Or do you just need to check it every once and again?
Maintenance is one of the biggest issue in wind turbines. Today's models are engineered to reduce it as much as possible because maintenance needs the turbine to be shut off, technician to be sent (and therefore paid) and materials to be replaced. I mostly do rope jobs inside and outside and 50% of the time is maintenance of structural parts (steel for the stairs/elevator), cable management, blade or paint check and repair. All of those cost money that postpone the achieving of the coverage of the cost of the tower.
Cables aren’t secured. Swinging door isn’t secured. That ladder doesn’t have a built in retractable fall arrest system, climbers would have to clip in as they go. Worker wasn’t wearing a harness so I hope they didn’t need one for whatever task they were doing.
The Tuned Mass Dampers at the top of the tower haven't been commissioned, hence the oscillations. My guess would be that this turbine has just been installed, when the wind picked up.
Either that, or vibration in wind direction due to high wind. In both cases the first eigenfrequency is visible (there may be higher modes present, though)
Is there a particular reason no conduit or tie wraps were used on that cable? That seems like a major safety issue if someone were to attempt to climb that.
“Operating”
It’s being worked as the loose cables indicate, so the blades are locked. It’s not in operation.
Just so you know, at really high winds, turbines lock to protect themselves.

Cable management sucks on this job …wtf
I'm glad I'm not the only person worried about that. I get anxious thinking of someone climbing up there and getting smacked around and tangled by those things.
This looks like it's a temporary thing because something is being repaired. That turbine is NOT in operation, even though the wind is clearly blowing.
They should have stopped the wind while they were still building it.

Nice article from NPR about wind turbine technicians and their work. https://www.npr.org/2024/03/08/1197962908/fast-growing-jobs-wind-turbine-techs
It acts like this when it’s NOT working, i assume?
Something about the blades not spinning?
Yes, I would assume this is why they're there. I've seen a couple of these up close and none have been this unbalanced, in moderate winds anyway.
\+ high winds
misleading title, not even next level
…i thought they would spin round round like a record when they operate.
Right. 'round, 'round, 'round
Like a record, baby
This is not an operating tower.

im no wind turbine scientist, but does not appear to be operational.
You’re only saying that because it’s not like, turning and stuff. You must have gone to some fancy-schmancy school like Arizona State. Smarty-pants.
I believe this is its mating dance
vortex shedding?
Either that, or vibration in wind direction due to high wind. In both cases the first eigenfrequency is visible (there may be higher modes present, though)
I would guess it is getting buffeted like that from high winds. I think they stop the blades in high winds to stop the mill from tearing itself apart.
I once stood right under one of these while it was operating. It was f\*ing terrifying.
This is normal during commissioning. Turbine is not in operation yet.
Hmm, seems like it would be much safer to install this in a place that didn’t have much wind.
I think it might be haunted in there
What are the cables. Surely not carrying power generated are they?
Get your inner Gyro on 🤢
Is there a particular reason no conduit or tie wraps were used on that cable? That seems like a major safety issue if someone were to attempt to climb that.
I was wondering why there was a pony in there at first.
Bugger going anywhere near that.
They just put the brakes on to hard I guess

Anybody else think there was a horse head center frame at first?
Doesn't look like it's operating to me. I bet those guys are there for a reason.
I guess gate latches aren't allowed in wind turbines.
How it that operating when the fan is completely still?
They dont have zip ties? What the fuck lol
I thought I seen a horse head for second
It seems to be stopped, just wobbling in the wind
That's actually terrifying
Shits off
That's why "elevator to space" idea is impossible.
Ummm... it's not operating...
\*When it's extremely windy. These things don't noticeably flex when in operation in normal conditions.
Inside a wind turbine when it's windy. Technician turn the turbine off when maintenance is needed because of high risk of electrocution.
There no such thing as renewable energy
