Gas Turbine Accident

6.5 million dollars blown in a few seconds

[@kimmer6]

As a General Electric Company Field Engineer, I installed many turbine rotors like this one. Usually I put them in a little slower.... I'm certainly glad these guys emptied their pockets before getting near the open casing.

[@ronalddavis]

You wouldn't happen to know the old guy who worked on the sl-7 ships awhile back? I worked with him on a couple of ships back in the early 2000's,he must have been in his early 70's back then...Nothing he didn't know about steam ships. Could be an ornery old bastard though.lol.didnt much care for black folks. cant remember his name only that he was a GE rep.

Lol Will, the stator is the name of the part that goes in between the turbine blade sections in order to prevent the gas from rotating as it flows through the turbine, and the bearings are clearly visible in this video…

[@GeekBoyMN]

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.

[@eldorado96]

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!

[@sciencoking]

Gonna need a _lot_ of duck tape for this one

[@TheCalgarycanuck]

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.

[@TheCalgarycanuck]

That sling held, crane didn't.

[@ronalddavis]

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.

[@vincentrusso4332]

Load brake not adjusted properly was another issue a former crane operator brought up.

[@kennyfreeman9278]

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.

[@vincentrusso4332]

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

[@GeneralWagner]

almost dropped a tear here, what a beautiful turbine, and is gone in seconds, because a fucking crane. loss like this can bring down a company

[@bonjourmssr]

+GeneralWagner Is the turbine even salvageable? As in re-machine and balance, or just build a new one??

[@furnacify]

+bonjourmssr Yes its salvageable but very expensive, and it will cost 1-2 years. The rotor is too damaged. 180 degree on the underside, and in the upper center from the traverse impact. 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.

[@Holiday48000]

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

[@AndrejPodzimek]

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.

[@rearspeaker6364]

+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.

[@rearspeaker6364]

+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!!!

"Gas Turbine Accident" that sounds like something id enjoy

[@ChuckHeil]

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.

Nomeclature Issue: STEAM TURBINE is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. GAS TURBINE, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between.
