    i remember a greentext about this, and a wiki article, but where is it again? I thought it was the Norwegian oil platform disaster but no

    there was some talk about how they got discombobulated and their bodies had gross dismemberment or something, being entirely suctioned through

    edit: aha, found the article!

    the causes:

    • employees were overworked
    • bad audio and noise caused miscommunication
    • entry/exit door was unsafely designed
    Colourful NSFW description ahead

    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 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. These were projected some distance from the bell, with one section being found 10 metres vertically above the exterior pressure door.

    I mean the dolphin story is gruesome. But for this diver to get a severe injury he must be very close to the hole, almost touching it.

    The suction power is not that great in an underwater scenario.

    What made the dolphin so gruesome is that it was an explosive decompression and besides the driver closest to the door no server dismemberment took place, only a very sudden decompression making for a very sudden yet horrid death.

    If the diver in this diagram keeps a couple of centimeters away from the opening he is completely fine but if he manages to cover the outlet hole with some of his anatomy, the shit hits the fan.

      I hate “delta p” so much, as in the term. I’m convinced divers just used it so they could sound even more elitist and like astronauts when they’re just dudes with a few grand and nothing better to do. Erm, akshualy that isn’t a vacuum, that’s a device that’s creates delta p. P stands for pressure and delta is a scientific notation for change. Cool dude, now finish delta p-ing your fucking room.

        Static pressure on it’s own doesn’t really “do” anything though. You could have the thinest piece of solid material with 10 million atmospheres on either side and the material doesn’t care since forces cancel out. Difference in pressure is where shit goes pop or crush depending on the direction.

          This statement is incorrect. Pressure directly affects materials. Its just without pluging the hole with a part of your body you don’t actually feel the difference. In static 10 million atmospheres stuff like metal should show some measurable shrinkage. The larger the object, the more shrinkage you will measure.

          Divers frequently go to pressures of 500+ PSI without issues directly from the pressure

          Nearly all the issues at that depth are from the physiology of breathing gasses at that pressure

        Hey… Some of us just like blowing bubbles and hanging out with fish.

        It is pretty fun, but to be honest not worth the money if you have to pay for the training yourself, especially if you don’t live near a good diving spot.

          yeah, this is very true. I’d love diving tropical stuff every day but don’t want to live where it’s warm lol; where I live there are some crazy folks who drysuit dive all the time, but even then it’s waaaay too cold for me. I want the water warm but the rest nice and cool lol

            I’m one of those crazy drysuit divers. I’m usually plenty warm on a dive, and seeing a pristine shipwreck at the bottom of the great lakes is pretty awesome

    Is that enough pressure differential to injure you? Get stuck yes but 6.5 PSI doesn’t seem that crazy.

    I’m not sure if this is triggering either thalassophobia or submechanophobia but either way thanks I hate it
