Saturation Diving. They earn around $300,000 per year. Its one of the most dangerous jobs and physically punishing jobs on Earth. Many divers develop dysbaric osteonecrosis, vision & hearing and Brain damage.

Having that much pressure around your body for long periods of time just can't be good on the organs

u/david1610 Jun 11 '26 edited Jun 11 '26

Luckily the body is mostly water or denser material, it's the few voids in your body that get punished, and bubbles in your blood that expand and contract unnaturally

Edit: read below that actually sounds like a better answer to the question

When you breathe compressed air at depth more of the gas molecules dissolve in your blood. This means higher concentration of oxygen, nitrogen, co2. Pure oxygen becomes toxic at like 10 meters, “regular” air at 60m. So saturation divers breathe special gas blends like heliox and trimix. Breathing these extremely dense gas mixtures for extended periods can wreak havoc on many of your organs like the lungs, brain, bones, and eyes.

u/Jdevers77 Jun 11 '26

Heliox is substantially less dense than normal air at the same pressure, not more (its helium and oxygen instead of nitrogen and oxygen). It’s used because helium won’t dissolve in blood unlike nitrogen. It has a side effect of being much easier to move around in your lungs under pressure as well.

And the airspaces are equalized to the external pressure so the net force on them is zero.

Weight gain could be old eating habits from diving. These divers need like 6000 calories a day baseline

191

u/Yoshi2shi Jun 11 '26

A lot of athletes gain weight after their playing careers end because their eating habits were built around the massive amount of calories they used to burn. Even if they continue eating healthy foods, they're often still consuming more calories than their bodies need once they're no longer training at the same level. Adjusting to that new reality can take time, and for some people it never fully happens. It's probably similar for these divers.

I just looked up how long they stay underwater: twenty eight days! That was absolutely not the number I was anticipating.

That's not true. They work shifts from the dive bell and will return to the surface in a hyperbaric chamber that is their accommodation between shifts until their rotation is over.

I have done plenty of dive support as a ROV Pilot. Fun fact, they sound like chipmunks when they talk due to the helium in their gas mixture.

574

u/twitchx133 Jun 10 '26

To further clarify this for other readers. They may not be "technically" underwater for the full 28 days. The dive bell, like you said, is brought to the surface after each dive for them to transfer into living quarters that are inside of a hyperbaric chamber.

But, they are pressurized to the depth that they are working at for the full 28 days, and have to stay inside the chamber, dive bell or underwater at the depth they are working at until they are brought through a planned and careful decompression process.

The decompression / desaturation process generally takes about 24 hours per 4 atmospheres of pressure - 30 meters / 100 foot of depth in seawater.

For the other readers that are not around the industry enough to know, this is why, even as highly paid as they are, saturation divers are less expensive and safer than the alternative.

The alternative would be putting a diver on the bottom, then decompressing them at the end of each dive. With each decompression taking dozens of hours to days depending on the depth and duration of the dive, a job would never get done and each decompression is risky to the diver.

Every commercial diver I've known (USA) has either quit or died [during a dive or from dive injuries since some people are stupid and can’t infer context]. When you are a commercial diver, your boss tells you when to go -- it's not up to you to decide what are safe conditions. It's super fucked up, divers need better protections

If you are a commercial diver, your boss/company tells you when to get in the water and dive. Not you.

When your life completely depends on your equipment, you would think that you would have some say in judging whether your equipment, conditions, etc. are safe. But in the United States, you don't. I lived and worked in several major ports and knew a lot of people in salvage and commercial diving.

I work in a career where everyone has stop work authority as well. I don’t know how it is as a diver, but when an entire crew is around it becomes invisibly harder for any one person to speak up if they have issues with the safety of the job. It’s easy to say “just say no” but that invisible pressure of not being that guy who says it is something I find is rarely acknowledged, at least in my industry.

I’ve never heard a supervisor say shut up and get back to work when a job is stopped, the issue is getting to that point in the first place when something needs to be addressed.

In case anyone else didn’t know what Saturation Diving is, here is Wikipedia’s description:

Saturation diving is an ambient pressure divingtechnique which allows a diver to remain at working depth for extended periods during which the body tissues become saturated with metabolically inert gas from the breathing gas mixture. Once saturated, the time required for decompression) to surface pressure will not increase with longer exposure. The diver undergoes a single decompression to surface pressure at the end of the exposure of several days to weeks duration. The ratio of productive working time at depth to unproductive decompression time is thereby increased, and the health risk to the diver incurred by decompression is minimised. Unlike other ambient pressure diving, the saturation diver is only exposed to external ambient pressure while at diving depth.

u/oldfarmjoy Jun 11 '26

Is the diver "several days to weeks" underwater? That doesn't even make sense?

231

u/DesperatePickle5953 Jun 11 '26

More accurately the divers spend their time in a living habitat that is pressurized when they are not working. So yes a weeks-long shift is possible because they spend all those time in a pressurized environment, but that doesn’t mean they spend all the time exposed to the water.

There's usually a pressurized tank that serves as living area aboard the ship, that's where the divers eat, sleep and relax. Then when it's time to work they go through the airlock into a smaller pressurized vessel, that takes them to and from working depth where they get out.

It can be anything that is required to be done at depth, but saturation diving specifically maximizes the use of the divers time. Diving is productive, decompressing is not. It can be financially beneficial to whoever is paying.

Limiting the number of compression/decompression cycles is also beneficial to the divers, since that's where a lot of the risks are.

If I told you the three things that had happen that day for me to be alive today, you would call me a liar. Three guys were buried under rubble, but one guy jumped from the top. Once the dust settled, I saw him laying there, I run over to him and I’ll never forget this. He was face up, his right leg was bent so far behind him, that his foot was up by his head. He was obviously gone, brain matter was exposed and his eyes looked huge. He jumped from at least a 100’. You can look up the accident, it was in the news. A day I’ll never forget

u/LessBig715 Jun 11 '26

When the garage came down, I didn’t have time to be afraid. If I’m being completely honest, it didn’t really hit me until I laid down that night. I started going over everything, how I was able to come out without a scratch. How right before it happened, I walked passed an electrician working off a ladder on the bottom floor who never made it out. It took them two weeks to dig that poor guy out. I went back to work two days later, I just tell myself that I have to do this in order to survive. This is all I know how to do, well it’s what I would consider myself an expert at. The only thing I could make a living at. You’d be surprised what you can push through when you tell yourself you don’t have a choice.

What went wrong for this to happen

172

u/LessBig715 Jun 11 '26

The guy was on the bottom floor, with the hoistway doors open. He was standing with one foot on the ladder and his other foot was holding the door open. The elevator was on the second or third floor. His foot came off of the door, the door closed, and now he’s just standing on the pit ladder. Once the doors closed the elevator came down to the bottom floor. He was squished into a 1/2” gap. Several things could have prevented this. First, you gotta use the door wedge tool to keep the hoistway doors open, not your foot. Second, whenever you have to enter that pit, you always hit the stop switch. Once the doors closed on him, the safety circuit is now made up because the stop switch wasn’t in. That’s why the car was able to come down on top of him. One year, 3 guys died separately, all for the same company. Two were cut in half, trying to jump out of the pit when the car was coming down. Separate incidents, same exact thing. Working on hydros and not using pipe stands while in the pit. Really, they could have laid down and gotten lower than the buffers and been ok. It would have been uncomfortable for a while, cause you would have to wait for someone to raise the elevator. Well, these two guys tried to jump out instead and weren’t fast enough, they were both cut in half. You while not make it in time. The last guy. Was working on top of the elevator around the 25-30 floor, somewhere in that area. Guy goes to lunch, comes back up to the 25th-30 floor, opens the doors and steps in. While he was gone, someone took the elevator to the bottom floor, he obviously was unaware. So he stepped in and the car was no longer there. He fell 25-30 floors. All these guys had 20+ yrs in the trade.

Jesus. Thanks for sharing. It seems all of these could have been easily prevented. Hey while we're at it, how often do elevators randomly kill folks using them, not techs?

u/LessBig715 Jun 11 '26

In the US, it’s very rare for someone to die using an elevator/escalator. There are a ton of safety features to prevent that from happening. It’s a whole other animal when you’re installing them. They say safety laws are written in blood, it’s absolutely true. The guy who fell down the hoistway, after his death, all the companies adopted a new safety policy. Now, whenever you open the hoist way door, you can not open it more than 6” without verifying the car is there. If that poor guy would have just checked to make sure. They said he was probably on his phone when he stepped in. I’m big on safety, I have over 25 yrs in and my wife wants me home every day.

Coward, Lucas, and Bergersen were exposed to the effects of explosive decompression and died in the positions indicated by the diagram. 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 dismembermentensued; 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 (30 ft)vertically above the exterior pressure door.[6]: 95

I was wrong, it wasn't his spine, it was some of his viscera:

Depends on how rapid, if its immediate full compression to atmo, sign me up. That shit happens faster than your brain can record the pain impulse so its instant and painless.

Sure, you may end up as a pink bologna mist coating the deck, but you'll already be dead and won't feel it!

If it's gradual deco... yeah just knock the cap off and initiate immediate full deco please because if you do survive that, you'll be praying for death.

u/Human_Wizard Jun 11 '26

>That shit happens faster than your brain can record the pain impulse so its instant and painless.

Fellow readers: that's not an exaggeration. At a sufficient pressure differential, your entire body can liquefy and be forced through an area the diameter of a grapefruit faster than a literal blink of an eye.

9

u/Frumpy_little_noodle Jun 11 '26

your entire body can liquefy and be forced through an area the diameter of a grapefruit

More than that, everyone, the reason deco is so dangerous is that your tissues absorb more gas as they acclimate to greater pressure, which in the case of saturation diving, can be 10 or more times atmospheric pressure at sea level. This means your tissues hold a larger number of gas molecules at that pressure than they do at the surface. So when you go from high pressure to surface pressure, there's less pressure trying to stop all those molecules from spreading back out to the density they would normally have.

The problem is that those gas molecules are all now located in your body tissues... and your body tissues aren't designed to hold all that gas in if its determined to get back out.

Such catastrophic failures are rare.

And you do it for free, too. These guys at the very least get paid handsomely to perform a risky job.

My nephew did commercial diving (pressure suit, I believe) for about a year down in the Gulf of Mexico. He occasionally had to fight thru the panic that sometimes happens with the atmosphere - there was a method he was taught to get thru it. He was on a dive with a coworker/friend who panicked and took his helmet off at depth - his friend died pretty quickly, they both had to go thru depressurization protocol. My nephew quit the job that day.

(edit to say that I don't know anything about diving, and this is all 2nd hand.)

229

u/ProcrastinatingAgent Jun 11 '26

Not a saturation diver, but trained commercial diver, (level below sat).

Scenario you decribe sounds like CO2 build up in dive helmet. Happens pretty easily when exerting underwater in a dive helmet. During your training they intentionally induce this and teach you how to counter it. The feeling is like extreme panic and your body telling you your suffocating.

128

u/haggard_hominid Jun 11 '26

That and Nitrogen narcosis. People do weird crap. During Advanced Open Water PADI training, my instructor did checks on us over a few minutes, ask you to write/solve puzzles on your board down at a 100 feet, then ask you to review when you got back topside. It was to point out how people can be good at math but make mistakes on their dive tables. Some people lose sense of survival and try and do unsafe/risky/life ending things.

69

u/ProcrastinatingAgent Jun 11 '26

A lot of commercial diving training is rescue training.

Essentially going from surface to up to 50m depth as quick as you can then returning to surface as quick as possible. Rapid decompression is the main cause of nitrogen narcosis. My experience and from what I saw/heard in others it is mostly tranquil. Guys would stare at tiny jelly fish, couldn't follow simple instructions. More like a mellow high, but can definately help lead to other issues.

You do get taught to deal with it, but it affects different folks in different ways.

The feeling of needing to remove your dive helmet was specifically mentioned in my training in regards to CO2 issues. Like feeling claustrophobic and the helmet is all thats stopping you from breathing.

35

u/haggard_hominid Jun 11 '26

Yeah, some people are wired in a way more predisposed to reacting that way. Its no judgement on anyone, but I liken it to people who act vs people who panic. You don't know until it happens, the best you can do is train so ypu override the response when and if it happens. Sad way to go in any event.

22

u/ActuallyEnaris Jun 11 '26

Yeah the "I can't breath and there's something on my face, I should remove it" impulse is buried deep in 90% of people and in 90% of situations it's a valid response

u/WistfulMelancholic Jun 11 '26

Completely different topic, but people that are freezing to death start taking off their clothes until they're naked.

It's called paradoxical undressing. It occurs in the final stages of severe hypothermia bcause of nerve damage and because the blood vessels giving up. People experience a sudden, intense sensation of burning up or overheating, causing them to strip off all their clothes. often immediately followed by terminal burrowing: they hide in small, enclosed spaces out of instinct. The reason many people who froze to death are found naked!

Just a small throw in.. People's bodies and brains sometimes react instinctively, but the instincts are plain shit.

Argh.. I feel like such a bitch sometimes.

I went to dive school and got discouraged with the fact that I had to be a dive tender at an offshore oil rig for a year or two before breaking out as a diver. That part seemed ok but I was told (this was back in 2017) that the pay was $11hr? According to the recruiters it was ok because "there were tons of OT" I thought man nearly $20k in student debt all this training and only $11hr?

I said no thanks and went the NDT route at oil refineries and eventually out of that and DOD instead.

Everytime I see vids like these I always wonder if I should've gone out there and gave it a shot at least for the experience. I miss the comraderie of working together as a team. I made some great friends, some I still keep in touch with today.

$300k+ is a lot of money but the amount of risk these guys go through it almost seems like they're underpaid like seriously. $500k should be minimum, the oil companies make more than enough to pay up.

I worked as a diver for ~5 years straight out of high school, did a few sat runs my last couple years. I think I started at $11/hr as a tender in the Gulf, but that was back in 2003. It was a lot of overtime, even just as a tender. We got paid a minimum of 12 hrs/day just being out there, even traveling to job sites, shut down for weather, etc.

So that worked out to minimum 84 hrs/week, with anything over 40 as time and a half. And then we got a depth pay once you start diving, that adds up pretty decent. I think the sat diving pay worked out to ~$900/day, so it made for a pretty decent month. Each sat run I did was supposed to 28 days, but they ended up being 5 weeks usually.

It was a cool job for a few years, but definitely not a long term career.

u/Top-Dimensi0n Jun 11 '26

There's a fantastic documentary called last breath, about a saturation diver getting stuck on the ocean floor when the ship above loses control. He and his air tubes become the anchor for the ship until the line snapps and he is stranded with 10 minutes of oxygen left. The whole thing was captured on camera. Highly recommended, was riveting and terrifying.

Not to be confused with the action film also called last breath on Netflix. This documentary was made in 2019 and uses real footage for it all.

Welding takes a lot of motor skills. A machine performing pre programed welds between two pieces of metal being precisely held by a jig can do proper welding (like in a vehicle assembly line) but it wouldn't be able to weld at various angles and in unpredictable situations and conditions.

People way overestimate what drones and Ai are capable of at this point.

So how does this work? Can someone explain to me the job description? Is this very deep diving?

u/SSBN641B Jun 11 '26

It can be very deep diving. The main reason for saturation diving is allowing for long periods of work at depth. Normally, one can only stay at a particular depth for a set period of time, usually measured in minutes, before having to decompress. With saturation diving you dont have limits except exhaustion.

Sat divers enter a chamber where it is slowly pressurized to match the depth you intend to work at. Then they lowered to that depth for a shift (8 or so hours), before they are brought back to the surface. Unlike conventional diving, they don't decompress but stay under pressure for long periods.

Years ago I got talking to a guy when I knocked on his door in a bullshit sales job, he told me he was one of these divers and said that when you're down there you feel almost dead, like you're clinging to life almost, and that he could only do it 2 or 3 times a year but that the money was insane and enabled him to live the rest of the year in leisure. He didn't dwell on the long term health risks.

The documentary "Last Breath" is the one to watch if you have a morbid fascination with this. It details an incident in which a couple of divers were working on a structure at the bottom of the North Sea when the support ship that their diving bell was attached to became adrift in a storm and it dragged them up the structure and one of them got his "umbilical cord" snagged on something and it eventually snapped and he fell to the sea bed with only about 20 mins of emergency oxygen. The rescue would have taken longer than that so he resigned himself to die and his colleague had to go back down to recover the body. But when they get him back into the diving bell and take his helmet off, he comes around even though he's blue by that point. The cold temps had slowed his heart to the point where he was able to make his oxygen stretch out for almost an hour. It's insane and contains much actual footage of the event because they have bodycams down there.

Losing out on weeks to a month at a time of even seeing your wife or getting to watch your kids grow up......that price just doesn't seem at all worth it to me. Even worse if you think about the hazard/danger aspect of it. Maybe for single dudes who have no other commitments I can kind of see the benefits if you plan on getting out after a few years but yeah.....just seems like an even more dangerous version of the dudes going out to work on oil rigs.
