A sober one.....
The bends would have killed him in a quick ascent. After rescue, he spent 60 hours in a decompression chamber. At 100 ft., he’s at 43 psig compared to 0 psig at the surface. A lot of nitrogen is dissolved into his blood at that pressure.
There's no rescue with Obamacare.
Amazing I would say it is a miracle.
All submariners are trained in escape from depths of over 100 feet from an escape chamber. The air is compressed in the lungs at the depth, and there is plenty of air/O2 to come up. What MUST happen is that one must exhale all the way to the surface, and not hold one’s breathe. Holding breath means expansion of lungs (and gases in the blood), which will kill an individual by bubbling in the blood, or explosion of the lungs. Many is (or were) the WWII and other submariners who could tell you some horror stories about this.
The Momsen lung was designed to assist escape from a submarine at depth and provide support to breathe out as needed— and saved a lot of sailors. Invented by “Swede” Momsen.
I came up with 299 kPa gauge. I can assure you that my calculation was easier. I loathe having to do any calculations in ft-lbs, psi, or BTUs.
There are tanks that are flooded with water to give it weight opposite the lift or water is pumped out to give it bouncy on the side with the lift.
The pumps are big enough that they will flood or drain the tanks even with the load being swung from one side of the ship or barge around to the other side.
When the lights go out on a ship you can slap yourself and not know who hit you.
Complete darkness.
Trying to find your way around in that kind of darkness even when upright on the surface is tough.
27.7 inches of water ~ 1 psig. Easy to do. Learned it in ME and the boiler business (dealing with flue draft) many, many years ago. It’s one of those things that just sticks with you.
Even if memory fails me, there’s always http://www.onlineconversion.com/pressure.htm to assist.
As one of his friends understatedly wrote on Okenes Facebook wall, I feel sorry for u that happened man. Dozens of other friends and family members thank God and Jesus for looking out for Okene, though perhaps a hat tip to physics is in order, too.
I watched the video yesterday - a very lucky man. The South African rescue divers were superb, first rate.

And just who do you think invented the law of physics and all the other laws of our universe?
Yeah, I think God knew what he was doing when it came to physics.
I thought one atmosphere was 14.7 psi or 1013 millibars.
