Jiffy,
Serious questions, meriting serious replies.
And I don't know why I'm still awake and doing this, but let's go.
"Saturation diving from what i have learned from this documentary is another world indeed.
What are the long term medical effects on a diver in choosing to spend so much time on mixtures of Helium and Oxygen , ie 28 Days? "
Sat diving is becoming a bit 'old hat' for HSE reasons. But I have some friends who have been (one still is) in that side of the industry.
The jury is out regarding longterm 'medical effects'.To the extent that 'consensus' is now that it all depends on the individual. Physical and mental state, the way they behave when 'back on the beach', and so on.
I also have good friends in the 'technical diving' sphere, regarding caving. Five of whom were on that rescue thing in Thailand last year. Using some complicated 'mixes'. And I've been involved in some record-breaking 'deep and long' speleological dives in France. Not as a diver myself, I hasten to add, but doing logistics, buying the gas, comms, etc.
And yet again, it's the person which counts in the end, their mindset, etcetera. Or at least, that's my humble opinion. And I mean that 'humble' part, 'cos I've done a bit of cave-diving myself, but I take my hat off to those blokes.
Also, way back when (now I'm entering oilfield anecdote country) I had a friend in the early 80's who was a 'sat diver', but got into a new thing, which was 1 Atmosphere 'diving suits'. The way forward. A thing called 'JIM', manufactured by Slingsby, the glider-plane people. Essentially, it was a sort of underwater spacesuit, with controls to match.
He and his wife (and I and my wife) lived about a mile apart in the hills outside Alford, in the Grampian region. Good friends, and drinking-buddies. And occasionally we'd drag-race on a nearby road (if we'd have enough to drink). His Daimler CV8 against my Rover P5B Coupé. Always a close-run thing.We survived, nevertheless.
But one hitch, we ended up on the same rig. The ODECO 'Ocean Oddyssy', which had just been towed over from Newfoundland to work N.Sea, manned by the most rag tag and bobtail crew one could imagine. And there was a tremendous storm which put us on bigtime downtime. And during that downtime, my friend let me get into 'JIM', his 'underwater spacesuit'.
On surface, of course, not going underwater in it.
Now I cave ,I've cave-dived, I'm not a claustrophobe. But when he closed the sort of plexiglass helmet over me after I'd climbed into that JIM submersible thing, I was frightened, banged on the 'lid' and got out. Quickly.
Divers are special.
Btw. 'JIM' 'leaked' one day, my friend was lucky enough to resurface in time, and quit diving. Got divorced, and killed himself in a car accident twenty years ago. Deliberately, I think.
