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!
employees were overworked & entry/exit valve 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.
