Gas Turbine Accident

[@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.

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.

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.

[@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.

[@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

[@seenfromsweden]

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?

[@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.

[@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.

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.
