The solution to not dying in the aviation world is requiring periodic non-destructive inspections (x-ray, borescope, etc) and removing equipment from service on a schedule BEFORE it shits the bed. These processes are also used in civil aviation. Letting anything in a refinery go forty years is absurd. It's only steel and the industry is far from poor. Lost production alone should be motivation to replace old equipment long before failure but you cannot trust industry to care about anything but short term profits.

It really is absurd. I work at a paper mill that was originally built in 1957 and we still have equipment in use from that time.

Here is the thing, the civil aviation industry has the constant threat of this little thing called CLASS ACTION LAWSUITS and that their profit margin is reliant on their public image. Most other industries don't have that keeping them in check. Also, a lot of the equipment lasted this long is due to to the fact that when they were made, they were basically Ragnarok proofed and had oodles of spares on hand. I go to a forum where a fellow member worked at this factory that worked with industrial dyes and plastics and had to work with these machines. Just to STARTUP these machines means thousands of dollars and take an entire DAY to properly start. Since stockholders have a 'I WANT MY ROI AND FUCK ALL ELSE' attitude, running machines, equipment, and buildings beyond their breaking point will continue and damn the consequences. So, you'll have to make the stockholders responsible but that would absolutely wreck your ability to have an economy...

Me neither, and I'm a Libertarian. Only an asshole or somebody making money on the issue thinks that straightforward, accurate and well-funded industrial accident analysis is an unreasonable burden for industries to bear. Any facility involving tremendous potential energy (be it chemical, electrical, nuclear or whatever) needs to have a neutral 3rd party breaking their balls unless you want the country to start looking like the Chinese e-waste graveyards or the Russian oil fields. "Acceptable risk" in these circumstances needs to be managed by an outside auditor, it's simply a fact. Industry always wants to blame the workers for being stupid while the unions always want to blame the management for being stupid. They're both corporations with a financial interest in the "other guy" getting blamed. I've personally seen atrocious accidents caused by both of these lines of thought, and most of the time, both management and the workers did something stupid. CSB/WSB, OSHA, and every other letter agency all have anonymous 1-800 tip lines for unsafe practices, and workers who call are protected by whistleblower legislation. It's just that (in my experience) 99% of workers either think "Not my problem, why worry?" or "I can't risk getting fired over this." Both of those attitudes are major contributors to lack of internal industry safety; if the corporations don't fear their employees narking on them, they know they can get away with virtually anything.

during design perhaps that Nelson Curve was used to justify the use of carbon steel because it would operate in the safe area under the curve. But then later it was applied incorrectly when the plant personnel did not use actual operating temperatures to check with the curve but instead used design values. They said the scaling makes the exchanger run hotter too. Since they used design parameters instead of actual running it gave them a false sense of security that hydrogen attack wasnt happening when it really was and resulted in less diagnostic maintenance and resulting in it rupturing.

X-ray, ultra sound and other technologies need to be employed. Lasers can measure inside and outside thicknesses and compare these to original specifications. Clearly a bank of three or four heat exchanges should be used to allow for such comprehensive shutdowns on perhaps an annual basis. Великий и Славный и самый Имперский ЛЕВ 🦁

Im sure the company/corporation hurriedly tried to destroy all documents to cover their asses as soon as the accident occurred. Such recklessness, all of the management responsible should have at least had manslaughter charges brought upon them. And hefty fines from the all the CEO's personal pockets to all of the victims family!

Why its happened directly after maintenance? I think the main cause due to wrong operation as they might not start it gradually which caused cracking in aged shell on a cold night.
@flailios8 жыл бұрын
Kuwaiti55 You're just speculating. The CSB found the cause to be HTHA, not metal fatigue caused but temperature variations. You're not only just speculating, you're wrong.

Kuwaiti55> When a process unit is started up temperatures and pressures rise until steady state conditions are reached. In this case it is possible the expansion of the S&T exchanger's shell due to temperature tripped the weakened shell. Consider an ICE car: most of the damage to the engine is done as it is heating up.

It seems that companies like this adopt an attitude akin to that of, it's better to let the plant run down leading to a catastrophic failure, killing workers in the process and a major loss of production and revenue than to properly maintain the plant leading to a safe workplace, minimal equipment downtime and higher production output.

I would like to know how they determined the crack lenght and depth after the fact. Wouldn't the explosion make that difficult to determine?

@Tindometari4 жыл бұрын
The explosion produces lots of fragments with fracture edges to study. Any pre-explosion fractures will have different features. Once the pieces get fitted back together like a jigsaw, the location of the pre-existing crack can be found.
@TheMetalButcher4 жыл бұрын
The fresh break won't look like the old crack. The ild crack will be oxidised and fouled. The high heat in the fire will make it more difficult to tell, but I'm sure the experts are capable.

Shows how there has to be stricter regulations because, when left to their own devices, companies would rather take more hazardous actions that cost lives than potentially spend more money that impacts their bonus.

It was a policy at my company to replicate the actions of the worker when the accident occurred usually resulting in injuries to the ladies holding the clip boards and taking notes. Most investigations into industrial accidents are attempts at determining the action of the worker at fault.
