Yeah I read about it. Definitely not the nicest way to go.
DELTA P 🗣️🗣️
The biggest problem is he’s engineering in Imperial instead of SI units.
This really Byfords my Dolphin
Wouldn’t this human in theory become a crumpled sausage like what happened to the crab by the leaking underwater pipe?
Not at 15 feet. I don’t know enough to say how fast the water would be leaving that hole, but it’s maybe a couple hundred pounds of pressure. If he even got caught, it would be super uncomfortable, but he ain’t about to get ∆p’d
If you wanna see a real crab-in-a-pipe situation, look up that Byford Dolphin everyone’s talking about
Yeah I read the entire Wikipedia entry on the Byford Dolphin and I almost threw up because how vivid the description is. I think this would be my third time saying this but that’s not a nice way to go (to die) at all.

Fuck all of this
The wildest part to me is someone having the last name Coward. The only way that surname makes sense is if it was changed from something worse like Kiddiddler.
They also alleged the accident was due to a lack of proper equipment, including clamping mechanisms equipped with interlocking mechanisms (which would be impossible to open while the chamber system was still under pressure), outboard pressure gauges, and a safe communication system, all of which had been held back because of dispensations by the Norwegian Petroleum Directorate.
Fatigue may also have taken its toll on the crew, who had been working for longer than 12 hours
Builder of the rig Aker ASA’s Gross Profit was 7.16B
Norway’s oil and gas tax revenue soars to record $89 bln
Imagine forcing your workers into more than 12h shifts, running on 30 year old equipment, the government straight up refusing to upgrade said equipment, while making billions in profits - they don’t call it gross profit for no reason…
Fuck all of this
Normally when people say this it is at least a bit of an exageration, but not in this case. That is some straight up nightmare fuel.
Heres a taster for those of you who don’t want to read the whole thing.
…bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen…
But where’s Saddam?
This unfortunately happened in real life.
Edit: other way around though. The divers were on the air side (habitable quarters) of the chamber.
For more clarification, they were on the high pressure air side. The kind of dives they were doing involved long periods of acclimation to the different pressures involved, so the diving bell was pressurized to 9 atmospheres. Someone fucked up, and the door opened. 9 atmospheres turned into 1 atmosphere very quickly, and the only good thing is that it happened so fast that the deceased wouldn’t have even noticed
If you want to see an episode of a podcast about engineering disasters which is itself, ironically, an engineering disaster, well there’s your problem
Just for what it’s worth, it looks like it was actually an equipment malfunction, not someone fucking up, that caused the accident. The company claimed the person fucked it in an attempt to cover their asses, and they were eventually found to be hiding the truth in a court of law.
Justice should be violent
No one fucked up, they finally settled on it being a mechanical failure.
Edit: the company and government fucked up, I meant to imply none of the divers fucked up.
The company fucked up by not updating their equipment, even though they knew it was outdated and dangerous
“The North Sea Divers Alliance, formed by early North Sea divers and the relatives of those killed, continued to press for further investigation and, in February 2008, obtained a report that indicated the real cause was faulty equipment. Clare Lucas, daughter of Roy Lucas, said: “I would go so far as to say that the Norwegian Government murdered my father because they knew that they were diving with an unsafe decompression chamber.”[11] The families of the divers eventually received compensation for the damages from the Norwegian government, 26 years after the incident.[12]”
They company fucked up, they did not maintain their equipment.
Some parts of that article are straight horror.
👋 not reading it
Same here, I’ll stick to this comment thread, thank you very much.
Wtf is a psi
It’s the Imperial Gangnam Style unit
It’s what you need to power your Protoss army
Muricas version of pressure.
It would kill you regardless of where you live
Freedom units
pounds per square inch. the us version of bar or n/m²
Why is your comment highlighted blue in Lemmy Connect?
100.000 PSI is equal to 1 bar(if I remember correctly)
Unfortunately no, 1 bar (1 atmosphere) is 100,000 pascal
PSI is pounds per square inch and is roughly 14.5 PSI to 1 bar, and to me, way less intuitive than bar
Ah thanks.
That’s metric
no, not at all. bar is a logical metric unit, psi is imperial. because the us doesn’t know what powers of 10 are, there’s never a nice conversion factor.
US uses both and is capable of conversion. It is unfortunate, but saying it doesn’t know powers of ten is pretty condescending.
Am I assuming correctly that we’re looking at a big succ-situation, where the diver will big forced through the tube no matter what?
It’s a difference of like 7 psi over an area of what looks like maybe 30 square inches, which would be uncomfortable to get caught in, but I don’t think you’re getting Byford Dolphined
from a different reply I understood the meaning of the last two words: https://en.m.wikipedia.org/wiki/Byford_Dolphin
210 lbs will certainly keep you stuck there though
Ahhh yeah that’s where I’ve heard it before, WTYP had an episode on that!
For fun you can search up Delta P to get to industrial horrors beyond comprehension
Ayyyy, a wild Well There’s Your Problem reference. By far my favourite podcast.
Is 5m enough for that? I feel like no, but i have no idea.
Yup.
When it’s got ya, it’s got ya.
I’m unfamiliar with fluid dynamics. How intense would the Delta p problem be in this situation?
Soup like homogenate
Investigation by forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, gross dismemberment ensued; it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine. These were projected some distance from the bell, with one section being found 10 metres (30 ft) vertically above the exterior pressure door.
Soup indeed.
a section of small intestine
Huh. Weird. I wonder why that stayed in place. I mean, I wouldn’t have thought that you can squeeze out a person like a tube of toothpaste but since that is apparently a thing…
I feel like a delta of less than 10 psi doesn’t sound so bad
It depends on the size of the opening. If it’s small that’s no problem. You could block a 1 inch pipe at 10psi with your bare hand and be largely fine. It’s a little less than 10 pounds of force assuming a round opening.
The problem is that the total force scales geometrically with the size of the opening. Make it two feet wide at the same 10psi and now you’ve got about 4500 pounds of force trying to push you though that opening should you find yourself in the unfortunate situation that it’s been completely blocked by your body.
Yeah fair play to the big opening issue, I was picturing 1-20cm holes
Big succ P
I don’t see the problem.
I mean, I don’t swim, but the dynamics seem to make sense.
What am I missing?
Edit: Ah, don’t go near the water passage, right?

Like that, but with people.
Ouch!
And just to think, we’re all gradually evolving into crabs…
no we’re not carcinisation is a vastly overblown meme it’s other crustaceans in similar environments evolving into crab like forms as they already fill the same ecological niche and a crab body is perfect for that ecological niche any other creature is not evolving into crabs I hate the carcinisation meme
Do NOT put your dick or butthole there
Well if you have both, and disregard this warning, it will be hard to separate the two
Big ‘Guts’ vibes here
Water go sluuuurp, human go squish.
Is this like the end of that Aliens movie?
