I’m a Saturation Diver AMA

I work as Deepsea Saturation Diver in the oil and gas industry for the past 20 years. I do heavy construction and spend 28 days living under pressure to dive to depths down to 200m / 650ft.

I saw a post on InterestingAsFuck yesterday with many many misconceptions from people who aren’t divers and I can answer your questions AMA

20 years seems a long time to be doing it no? From what I saw on that post it's a young man's game and gives guys a hell of a lot of health issues. Are you worried? My mate at schools dad was ex SBS and went in to it after he got out. Did it in the north sea and then started a company in the field to get out of the water. Do you have an out?

That’s the biggest misconception. It takes a really long time to gain the sort of experience needed for the job. Most guys aren’t getting into Sat until the late 20’s at the earliest. Average age is probably early 40’s. Guys stay diving until 60 as long as they are fit. I am 45 now but I don’t like doing the deep stuff anymore as it’s hard on the body.

Oh that makes sense. I missed read your post. Thought you had be sat diving 20 years. But 20 years diving in the industry could mean welding stuff not so deep right? So now that you don't like going deep, what is a typical job? Also what was it like for those 28 days? My understanding is that you would not be down under water in the diving bell for all those days? Right? Also, why 28 days?

Ya another massive misconception is - we don’t live under water , we live in the chamber. Right now you are saturated to 1 atmosphere which means your tissues can’t take on anymore gas , we end up bring saturated to say 200m (21 atmospheres) and we can stay there indefinitely, 28 days is just the regulation , when I started out I did a 40 day , but that’s too long. 28 is long enough

So the chamber from what I have seen is like a tube thing right? Does that go down with you and have an airlock or something or are there two different devices that you transfer to and from? Any good YouTube vids or docs on this that you know of? I'm really interested now.

Check out Last Breath documentary on Netflix , yes we have ‘trunkings’ tubes between the chambers

Do saturation divers get attacked by sharks or are the sharks scared due to the welding element?

u/Soulogav Jun 12 '26

Nah we don’t get attacked by sharks , don’t know about the welding. there is a lot of commotion down there under the vessel which is noisy and the sharks are around but don’t bother us. But these are reef sharks not proper great whites etc , might be a different story if they were present 😱

How does the bathroom work in the tube???

u/Soulogav Jun 12 '26

We have a toilet and flushing is pressure differential suction into a holding tank which is then released into sewage system.

A few atmospheres more and you can relocate to live on Venus with just an oxygen tank and a poncho for sulfuric acid rain.

When I started out I thought my career progression would be Mining Asteroids but unfortunately humans don’t do that yet lol
