I have worked around cranes for 36 years. Driven them about 12.I have never seen one fail that way.Generally people working beneath cranes seem to think they have nine lives.
Out of all the crane accidents I've seen in videos or read about, this is the first where a winch failed. It's usually a cable or some part of the actual rigging that fails. Either way somebody is out a chunk of money even if nobody gets hurt. Glad nobody was hurt in this one.
I know, I cringed sooo hard when I saw him do that. Imagine getting impaled by houndreds of compressorblades and then crushed by the whole shaft assembly.
"Psh... why order a fancy lift system for tens of thousands of dollars when I can get what's basically the exact same thing for only $599.99 at 'Harbor Freight.' I mean come on, no one will know the difference anyways!"
no body will go under load in any way...that guy was also doing the same to check installation...safety guys never allow to stand under even when one blade is being installed that was a whole set of Compressor and turbine with rotor...
I used to work for GE as a project specialist, One of the engineers gave me a copy of this 3 years ago.... This was in a plant in Germany... I remember this. thanks for posting it...
Worked on many a steam and gas turbine rotor swap as a millwright with no problems, that rotor would weigh less than the cover which was removed first, the crane would be rated to handle the cover weight, it appears the hoist coupling failed.
Yeah looked like they had it rigged right. Spreader beam and plenty big enough straps. I have been involved in many rigging evolutions and you can get complacent sometimes.i worked in the shipyard and sometimes because of space constraints you HAD to get under the load in order to land it. or refuse and lose your job.
I’ve done every part of this procedure many times, mostly as the crane operator, the notorious weak link of those crane’s were the load brake being not adjusted right, that one was having trouble holding the load, you can hear the motor over rev, this can cause multiple things to fail, usually the gearbox or coupling. They dropped the stator at my plant after I retired and killed a boy on the turbin deck.
Wow, thanks for the inside info with the load brake. I'm gonna say that you are spot on with your diagnosis. I'm assuming this isn't stateside so no OSHA report to read. Again, thanks. - Surry Virginia
Yup - love to know more about this one. So sad, seeing finely constructed hardware destroyed by cheap shit castings in the crane. I'm guessing that was some sort of transmission shaft with busted off engagement dogs. It explains that mechanical scream just before it came ALL the way loose. No excuse for not using forged components in that drive train.
"Uh, yeah... I just pissed myself... Over." "That's a big 10-4. So did I. Over." Christ those two guys down in the area close to where that turbine is mounted were very luck to have been able to clock themselves out that day!
This poor Crain Operator most likely received a lot of "Atta-Boy's" & pats on his back for the many good lifts in the past. But it only takes one "O-Shit" to wipe all them Atta-Boy's all out and lose your job.
@@politicallyinaccuratetoast4757 So who the hell gave clearance or issued permit. I work at CCPP and before every HGPI CI or MI we check the crane load test certificate it is mandatory.
+semmtexx thats a "fenner"coupling- used in the EU -fenner taperlocks adapt the coupling to the shaft--seen these in screening plants--when one looked like this on a plant, someone took a maul to it,because they forgot to loosen the 2 allen head screws around the taperlock to close the gap between the coupling halves.

Even the underside of the housing, wont look well. Mostly there will be replacement from another powerplant, which has gone offline. If there are more turbines of the same type in one plant, there is often a replacement rotor in stock.
+A.H. Shukry IMO, lack of daily inspections especially before heavy lifts like this---looks like the bearings at the input shaft of the gearbox failed, causing the shaft to load sideways under load, when the fenner coupling failed the input shaft broke thru the brake band asmby., causing the gearbox to freewheel, dumping the load, but thats my 25 cent review of this--mgt. saved a dollar, but they f%$#@ed themselves here!!!
janj0n whups!, ya let the bean counters do the talking, save a few bucks!, are you sure that part needs replaced?, this part is the new, and improved version!, it'll work much better.
Luckily, it seems that no people were injured in this accident. That's a very positive piece of information. Yes, the turbine is completely destroyed (since it cannot be balanced properly again, no matter how carefully it is repaired), but it's just a block of metal. A value of $6.5 million can be produced pretty quickly by a small team of people, but there is no monetary value that could compensate for human health or life.
My first thought is that the crane is overloaded. The brake can not hold the load when the crane operator lowers and stops repeatedly. The broken claw-clutch looks more like a result of another failed first. Am I wrong?
Go pee in the cup... Seriously though, it sounds to me like the winch broke. you can hear gears screaming and stripping right before the earth-shattering KABOOM!
Stress point- where forged hardened steel should have been used instead of cast on that particular component? I do not know, just saying. Thank you for the excellent video. It is definitely a learning experience for all, and I am glad no one was hurt.
I saw a replacement gas turbine on its stands waiting to be put in at a Nuclear Power plant around ten years ago. It didn't look to be real heavy. Not over 50000 lbs. A crane like the one that failed must have gotten their parts cheap or it wouldn't have failed. I'm sure it was rated well over what ever it weighed. But then a worker removing the cover of the turbine being replaced was throwing/flipping a wrench in the air while standing on the cover. This was in PA so who knows.
Kousheng nuclear power plant in Taiwan has an old turbine rotor on display at their entrance, sitting out in the rain, of all places. I wonder just how long it took to decon that thing to free release it, considering it's a BWR plant, and the turbines run on primary steam. :-o
+Jochum Bakker No way, this is not GE machine. It's not a Gas Turbine at all so Frame 9 shouldn't be mentioned in first place, it's a steam turbine and rarely this type of turbine is used in power plant because of its inefficiency.
Don't worry Jim....the maximum load rating is a guideline...these things can handle twice the recommended max...OH HOLY SHIT!!!! What do we do Jim? Jim??? JIM???? where are you running Jim????
Who has been doing the Crane inspections? Also when we did a heavy lift at the Power Plant on a Steam Rotor fitting in place and I was the Crane Operator when I worked there during one of our turnarounds. There was eyes on everything and QUIET during the lift. Wow very expensive. Thank god no one was killed.
+kc5hgv I was wondering why there was so much noise and normal day to day sounds going on during that lift. I even said out loud to the screen....Yo shut the fuck up....we are moving something heavy here... Everyone needs their ears on and eyes open at this moment.
+SquillyMon +SquillyMon Almost seems like they didn't have a foreman there at all. Just a bunch of grunts told to get it done with no former experience doing so.
@phanosh why do people keep commenting when they dont know what they are talking about?? READ... this turbine (ge 9e) its not a 'block of metal'.. its made up of 17 wheels for the compressor and 3 wheels, 2 spacers and 2 stub shafts for the turbine. this unit was not destroyed at all. it was a full unstack of the wheels, to change bent blades, and re-balance then put back together and balanced as a unit.. i fix these turbines for a living.
thats the reason you should always proof if your tools are in a good state. i think there was some error like overloading or nobody did inspect the crane since long time... such things should never happen!
The crane operator must've been so relieved when it became clear that the failure occurred because of the actual crane breaking, rather than his negligence
Large ones like that are still unlikely to be be monocrystalline. Though it is likely a 3rd generation superalloy which is the next best thing. Titanium, Nickel, and a few dozen other metals are the typical components. Then coated with ceramic blends for corrosive resistance and pitting damage. Hopefully single crystal manufacturing becomes easier soon!
Viewed it again and you're correct. I was still thinking about the accident when I typed that. That fellow in the yellow hard hat doesn't know how lucky he is to be alive. What failed?
that turbine looks way too heavy for that crane to lift. the popping and banging sounds were likely the crane structure itself failing, or the lifting system violently cracking
i work on gas and steam turbines for a living and this is a gasser. you could say this is the quick way of setting the rotor.the rotor itself is around 15mil let alone the other damage to the turbine itself.

@RochesterGT It has several compressor stages, and quite a distance between where the compressor and turbine stages are; obviously where a combustor section fits. This my friend is a gas turbine used to generate electricity.
@Skyisnotalimit Yes the 1st stage buckets (that is what we call turbine blades) have a ceramic tbc coating.. the cost is more like $20 million plus i think. I repair and build these for a living,.
@rogercardy That was the first hint that these guys weren't exactly Risk Averse. And as if the failing hoist and drop into the housing didn't cause enough damage, the hoist boom then had to crash on top of the upper vanes and damage them as well.
@leexr2i Why do people comment *before* understanding the point someone else tried to make? The "block of metal" statement was related to the value of a turbine in comparison to the value of people's health and life. Nobody said that a turbine consists of one single component. As for the damage: How can you be sure that the turbine would still be safe to operate after the repair you mention, with all the micro-cracks the accident must have caused to the turbine and housing?
Well...takes the time pressure off the other jobs during the shutdown. That made me sick watching that drop and knowing the lead times and costs of turbine parts. Wowsers...that definitely hurts in a lot of different ways!
I watched another version of this video which was narrated. The initial damage estimate (rough) was around 5-10 million dollars (US). I believe they said the blades were titanium. Lloyds of London, anyone?

@RochesterGT It has several compressor stages, and quite a distance between where the compressor and turbine stages are; obviously where a combustor section fits. This my friend is a gas turbine used to generate electricity.
Fire it up, I'm sure it's fine.
@Skyisnotalimit Yes the 1st stage buckets (that is what we call turbine blades) have a ceramic tbc coating.. the cost is more like $20 million plus i think.
I repair and build these for a living,.
skip to 2:24 if you want to see it.
@rogercardy That was the first hint that these guys weren't exactly Risk Averse. And as if the failing hoist and drop into the housing didn't cause enough damage, the hoist boom then had to crash on top of the upper vanes and damage them as well.
This is the problem when you turn a bunch of drunk union members loose on a project!
I stand corrected, thanks for the info. I wonder who's insurance gets claimed in that circumstance!
Im guessing the company cut crane budget.
@leexr2i Why do people comment *before* understanding the point someone else tried to make?
The "block of metal" statement was related to the value of a turbine in comparison to the value of people's health and life. Nobody said that a turbine consists of one single component.
As for the damage: How can you be sure that the turbine would still be safe to operate after the repair you mention, with all the micro-cracks the accident must have caused to the turbine and housing?
Well that's one way to do it. Larry, curly and Moe couldn't have done it better. Another job well done. Give those boys a cigar :)
@workonitm8 the shrouds you can see are not on the comp blades.. they are on the 2nd and 3rd stage turbine blades..
"Gas Turbine Accident" that sounds like something id enjoy
@leexr2i I thought so... The turbine blade probably have ceramic coating too?
I read somewhere that the whole rotor was worth $8.5 million....
Well...takes the time pressure off the other jobs during the shutdown. That made me sick watching that drop and knowing the lead times and costs of turbine parts. Wowsers...that definitely hurts in a lot of different ways!
I watched another version of this video which was narrated. The initial damage estimate (rough) was around 5-10 million dollars (US). I believe they said the blades were titanium. Lloyds of London, anyone?
Always check your gear kids, and watch your operating evenlope
Load test of the crane and material inspection (for example Non Destruct Test) should be carried out prior to use it.
