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
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
210 lbs will certainly keep you stuck there though
Is 5m enough for that? I feel like no, but i have no idea.
Yup.
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
The families of the divers eventually received compensation for the damages from the Norwegian government, 26 years after the incident.
Well, it's good that some justice was finally achieved, but that is depressing level of covering up (as usual)
But where's Saddam?
When it’s got ya, it’s got ya.
This really Byfords my Dolphin
anon's in trouble because they're using psi instead of bar.
Edit: also fuck high pressures are a scary thing.

Wouldn't this human in theory become a crumpled sausage like what happened to the crab by the leaking underwater pipe?

Fuck all of this
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

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.

You know how often a picture is worth a thousand words?
I feel like those words are worth a thousand pictures. All of them NSFL.
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
Let's convert to metric so we can tell.
15 ft is about 5 m.
Water pressure increases by 10,000 pa per meter (rhogh, rho=1000 kg/m^3, g~10m/s^2), so total pressure is 50 kpa, or 1/2 earth atmospheric pressure.
One side of that hole has ambient pressure of 1 atm. The other side has that plus water pressure totalling 1.5 atm.
A pressure is just an energy density. Multiply by the cross-sectional area of the interface to get the energy gradient across the interface. An energy gradient is a force. We don't have a measure of the cross-sectional area of the hole, but if we expect a person to fit through let's call it 1m^2.
50 kpa = 50 kJ/m^3, so total force felt across this opening is 50kN which is the equivalent weight of five metric tons.
Size of the hole absolutely matters. If it's only the size of a fist (10cm x 10cm) then instead of 5 metric tons it's only 50 kg of equivalent weight, or about the weight of a person and easily survivable.
Wtf is a psi
Muricas version of pressure.
It would kill you regardless of where you live

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...

Is this like the end of that Aliens movie?
is it just me or does this look like the cover of You Would Rather an Astronaut?
This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
