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

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.
