Danish turbine failure

[zzimmo]

Did this thing reach critical mach at the tips? Would be interesting to know.

[Pvjinflight]

Wind power sucks, its not powerful enough to be main energy source in most countries, Denmark is different as they have lots of high winds and no big forests and stuff to be against find.

[plokko1]

spy is sapping mah wind turbine!

[jasonfurmanek]

Failure 1: The braking system failed to slow down the turbine to a safe operating speed.

Failure 2: The blades have a certain amount of flex in them to prevent them from snapping under wind force. In this case they flexed too much and hit the support tower. Two blades hit at 15 seconds. The gear house doesn't explode until it is ripped off the tower by balance.

Regarding the nuclear safety issue: what do you do with the waste of a perfectly functioning plant? A: Try to forget it exists.

[HarvestmanMan]

Divide by zero error

[MammaleousMaximus]

think of it this way, if that thing would have stayed together, it would have generated enough power watch tv and use the internet for DAYS!!

[grnggrmn]

to eruestan7: Ever heard of Chernobyl? 1986? Try telling anyone living in the former exclusion zone, only 31 people have died as a result of nuclear energy. That thing's still burning its way to the center of the earth.

[Pvjinflight]

@grnggrmn They did not die as a result from nuclear energy, but from result of bad soviet design and wrong use of reactor, if you didnt know they were doing test that went out of control. Also Chernobyl had nothing but weak walls to cover it unlike western reactors. Chernobyl could not happen with any western reactor currently in use.

[eruestan7]

As much as people claim wind powers safety over nuclear, its simply not true.

Since 1970:

fatalities from wind power : 65

fatalities from nuclear power : 31 (and 0 in western countries)

Take into account nuclear powers huge energy superiority, and you have to wonder why we bother with turbines at all

[carpetmonk]

to put it into perspective, the camera was on a rigid mount, and the near instantaneous failure took a second or two, but it shook.. the ground, and the camera. i thought i read somewhere that it was the brakes that failed, but a general power failure would explain loss of all sub-system control. as for electricity, i imagine the lines couldnt take those amps,normally they rotate once a second. id love to know!

[Los10221996]

i wonder how much electricity was produced during that

[TheA340guy]

i still love wind power!

[ph0chiz0]

it hit 88 mph

[funkyironman69]

@ph0chiz0

88 mph..... ITS OVER 9000!!!

[fastzeek]

i spy the little gold sticker on the back that says Made In China! JK :D

[DerKrazieKraut]

what a piece of shit

[glasseay]

WUUUUPSII !!!!



[the731272]

at least it made a lot of energy before it exploded

[Cheaterblack]

Danish idiotes XD

[AdolfBieber]

@Cheaterblack not our fault..

[s1337Nx]

@Cheaterblack german bitch

[zequelll]

woah that was coool huuuuhuuuh

[triton115]

Perhaps it would be better if those windmills were made with adjustable pitch/featherable blades, so that in high winds like that, instead of using brakes that might fail, the blades can simply be feathered into the wind.

[Pacerace100]

I believe some of them have adjustable pitch blades. Not perfectly sure though.

[SwissLeo1]

Well thats crap.

[buffloriders]

when they test these, they have an engineer ride in each of the hollow turbine blades so they can facilitate a more complete observation of the critical falure. too bad none of these three lived...

[scrappyrusski]

no shit... the this vid must be strong wind testing

[americaneagle791]

It looks fake.

[JOCKATEO]

thank god no tinkers living there they would have taken the motor and nicked the copper

[barthmonster]

I've seen this during training at work... Or one just like it... The turbine in question was being worked on and had the brakes on. The brakes subsequently failed and with no generator-action to keep the speed at a normal level, it went into overspeed. Two maintenance people were killed. Like I said I think this is the one...

[adikidikki]

their big

so that speed is just crazy

i c them go at a slow rate

[Roserade]

I always imagined a wind turbine do that :D

[FJNricardo]

imagine how cool would it be if it started flying around

[OnnomonnomonnO]

loool

[cnknguyen]

I wonder how much power that thing was generating at the time of the failure. crazy stuff.

[Leonisgoed]

dang that's dangerous

[itsmacintosh]

the blades should have been flat. the brakes must have also been maulfunting scary stuff

[175myles]

holy crap! and they managed to get this in video how? was it a test? thats just insane.

[henrikmk]

Both brake systems on the wind mill were destroyed at the same time several hours earlier during a routine maintenance accident. The technicians decided to flee, because they were afraid the wings would fall off.

Then they learned from the weather service that the wind speed would only increase in the next 24 hours. There was nothing to do, as you can't stop the wind mill. They called the police and ordered everyone to stay at least 400 meters away and just film it.

[175myles]

would of sucked if you just turned round and missed it explode.

[DJcaliban]

rmerkle, embarrassing americans one thread at a time.

[bla7091]

Certainly this was quite a problem, in such a case the blades should simply shut down.

As for the location, once they're operative they can remain doing so for up to 100 years. At sea or in remote areas, they won't pose much of a hazard.

[nucleartractor]

That is totally incorrect, turbines are a black hole for money. The stress of the blades in the wind at the sides and top and then out of the wind when infront of the pole cause bearing to frequently fail and stress fractures in the material.

[bla7091]

So a wind turbine in a storm creates a black hole for money?

This one clearly isn't in the right place, or properly set up. Where I live they made a windmill park at sea, that's gonna be operative for decades.

Meanwhile, you get pretty much free power. Maintenance costs are nothing compared to oil/gas prices as they have been a year ago

[taagman]

Perhaps that was correct if you werent able to engineer it properly... but we are. But you just show you don't know anything about it. It's not the weak points on the windmill... the gearbox is the weak point...

[nucleartractor]

Wow. Lie to me, I don't care, just don't use my tax dollars for your failed technology.

[taagman]

Why on earth would I lie about it? The wings are insanly strong and flexible on Vestas windmills atleast. They can be bent in a U without breaking. The newer V90-3MW's are like Toyotas... won't ever get rid of it. The only reason you are sceptical about it, is because it's green energy... something that isn't cracy can't possibly be good economics... right?

[WarOnWind]

Wind wont work because the power it generates fluctuates

[JoelThedude4u]

So i guess no other power generating plant has ever failed in the history of power generation? no gas/ coal/ petroleum or nuclear powerplant ever failed? Chernobyl, tree mile island, and such? etc etc? and what did this fan did? break itself, not even fire. And it broke because a mechanism in it failed, because all human machines fail

[nucleartractor]

A "gas/coal/ petroleum or nuclear powerplant" will pay for itself PERIOD. Not to mention, three mile island released no radiation at all.

[JoelThedude4u]

but it could've released, there was the potential.

And they will pay for themselves in monetary revenue, but the money that will be needed to repair the planet from fosil fuel consumption will be far greater than any type of fosil fuel revenue ever gained.

[boa721]

oops, some one forgot to check the brakes?

[rmerkle9766]

If this what Oboma Plans to use for his "Green Economy". We are all going to have many more "Earth Days" to come. And they will last much longer than one hour.

[Karlfalcon]

What the hell are you talking about? How can you even make the mental leap to connect a windstorm in Denmark to Obama!? I guess some people are just sore losers.

Sour Grapes.

[rmerkle9766]

You totally missed the point dude. Unless you know something I don't, the windstorm was completely outside of any politician's control. However, if we are dependent on these junky alternative sources of energy we are going to be having many candle light dinners in the not too distant future!

[Karlfalcon]

Junky? This was a catastrophic failure. They happen to everything at some point. It happened to my American built GM when it threw a bearing and punched a hole in the engine block. It almost happened at 3-mile-island. I live less than 10 miles from a nuclear power plant that is slated to add yet another reactor quite soon because demand for power is so high. What would YOU have us "dependent" on?

[Karlfalcon]

From the Danish news at the time of the accident:

"The problems with the turbines abroad have had to do with poor maintenance, and if that's the case here, then I expect a clear report on how we can ensure this problem is rectified. We've still got about 35,000 wind turbines across the globe that are operating fine," said Peter Wenzel Kruse, Vestas's spokesperson. "But they're not infallible. We're doing what we can and learning from our mistakes."

[Karlfalcon]

Do you think the shift from steam to ICE's went smoothly? There are always bumps along the road to progress. That is the process. Find out what works best by finding out what doesn't and learn from it.

[Karlfalcon]

Do you realize how often they shut down individual generators at power plants for maintenance? Think of the filed of windmills as one big power plant. The mills are only the individual generators. If one is shut off it does not adversely impact the grid, since there are 40 others still running.

[rmerkle9766]

You just made my point. Our government is subsidizing junky industries: The American Auto industry, very expensive and junky cars and junky-expensive energy sources with high maintenance costs. Tell me this. Who is going to pay for all of this junk while they are profecting it ,when we already have safe and reliable energy technology and good reliable cars, like a Toyota. Why reinvent the wheel when it works so well?

[Karlfalcon]

You never answered my question.

What energy source would you have us be dependent on after the oil starts to run out in 50 years? Would you rather we find a new source now or would you have the world sit around twiddling their thumbs until the last minute?

[bla7091]

It won't run out until about 300 years from now. There's oil, natural gas and even coals. Below the north pole there will be a huge amount of it too.

That's not the problem, the real problem is: can the earth take it?

[Karlfalcon]

You see, right there you epitomize why the American auto industry is failing. Ad campaigns have for so long drilled the idea that Japanese imports are automatically superior into our heads that people stopped buying American cars, even when they ramped up quality to where they are now. Have you driven a GM in the last 10 years? I certainly take offense that you'd consider my 94 Cadillac "Junky." American cars are only expensive because most American owners are shit when it comes to maintenance.

[Djpara14]

Stop it on 00:17

End See it good

[omapps]

you don't need turbine anymore. all hipe.china invented a box fan like the one you place in your window. except it can be placed outdoors and produce the same amount of watts. now that's great news.

[SpiritsoftheWolf]

the hell with chinese knockoffs , i got fans that outlast these fans made in china. :P

[twiniver]

This accident happend in denmark not far from where i live (Aarhus). During heavy wind the brake function called "pitch" didnt work, that is when the blades are turned so they dont catch the wind. Its filmed with a cellphone in Denmark,by a man who happend to be there, allthough pilice warned the public against going there! As you can see on the cars they have dansih licenceplates. And yes we make excellent bacon, and windmills, however things can malfunction, and this sure did.

[limfiz09]

danish shud stick to making bacon

[TommyHansen1986]

Det så alt for fedt ud ude i halling hvor det skete og fuck hvor kørte den stærkt

[preacherboy244]

Hey, lets hang around a wind mill farm today.

[coolbluelights]

Looks fake.. like that plane that landed after losing a wing video.. wind would have to be hurricaine force for it to rotate that fast

[dec011984]

@omapps do you think it is normal for a wind turbine to rotate THIS FAST ? maybe sth. hit it and gave deadly hit but normaly they are regulated and THIS wasn't a normal speed

[omapps]

look at video in slow motion, the wind turbine didn't fail, it was a flying branch that was blow in to the blade that cause the failue.

[dickout1]

yer sure it was

[TCSC47]

I can certainly see the blade disintegrate and then the unbalanced rotor tears the whole thing apart. I'm not sure that something flies into the blade but there are branches in the picture, so it could have happened. I think it could also be a pure structural failure of the blade because the blades are certainly rotating far too fast.

Was it a test to see what would happen if they went too fast. Afterall why was the camera there in the first place?

[dickout1]

is that another vestas pile of shite

[redmight93]

LOL

[WhatIAm99]

You're going: "Oh, the blades are just gonna fall off...", and then BALAAAAAAAAAM!!!!!!!

[tvfilmglamdirector]

At 0:16 you can just make out the tip of one blade delaminating, the other two blades seem okay at that point. The failing blade then collapses and destroys the tower.

Great video.

[artgoat]

Do you know the diameter of the mill? It looks like at least 20m. That's WAY WAY too much RPM for that big a blade! Very cool that the blade maker got the chance to do destructive testing on them, though. That was probably 5X the RPM they were ever designed for.

[TyrantTG002]

And to think. Liberal leftwing retards want our towns and cities powered by these pieces of crap!

[UpBeatnik]

Pprobably one of the more ignorant, un-informed, useless comments I have ever seen posted to one of my vidz!

Vic Aguilar

aka

UpBeatnik

[TyrantTG002]

u-huh. Yep, well, they don't power enough on a large scale do they? The most they can power is probably small towns, shit like that.

But my comment is Un-informed? Please! Tell me everything you know about these machines!

[britoca]

use " the internets" yourself, it's at your fingertips

[NINxja]

They power atlantic city... last time i checked thats not a small town. lol

[TyrantTG002]

What else powers Atlantic city?

[TyrantTG002]

@UpBeatnik Yeah not my most powerful I'l admit...

[szlamx]

I don't care what powers my computer. If its a wind turbine, it's fine

[TyrantTG002]

So be it.

[markkragh]

@TyrantTG002 I suppose you prefer a nuclear reactor? Or coal power? Or how about flooding a few valleys to build a Dam?

[TyrantTG002]

@markkragh Fuck Coal power, fuck dams, but Nuclear? Hell yeah!

[skimowhite586]

@TyrantTG002 yeah so lets but gas generators in every home jeez fucking dumbasses i have seen more engines kill people than this shit

[TyrantTG002]

@skimowhite586 What the fuck are you on about?

[UpBeatnik]

The turbine failed because of a sub-system failure, that which governs the rotational speed of the blades. Tenacioused79 was correct in observing that the blades should have been 'feathered' (reduction of angle of attack)and a brake engaged to keep this from happening. Way less dangerous, or harmfull than Chernoble, Three Mile Island, Exxon Valdez, etc.

Wind Power Still ROCKS!

Sustainability or Death,

Vic Aguilar

aka

UpBeatnik

[erikcanada]

@UpBeatnik I think the sustainability or death is just a tad mellow dramatic....

[tenacioused79]

Something was wrong with that, In that high of wind the Blades Should have Been Feathered so it would Quit turning

[tkboyz]

was it because of the tree? or poor engineering on the wind blade?
