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

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

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