diving bell accident

close call rapid depressurisation
40 secs from death
The story I was told is that an engineer moved a main valve and in doing so neglected to reinstate the "dead-mans" type valve handle and changed it to a normal 1/4" turn. One of the three in the bell had knocked this valve open and because it can not happen by mistake normally they had no idea. Also you will notice the 2 divers stay clear and allow the bell man to find the problem, nice thinking. The mist you can see forming is the water vapour coming out of the atmosphere as the pressure disappears. Scary stuff and captured so well by the divers clear "for fuc# sake"

yes its the gas mix, google it for expanation. one of the things I find amussing is that one of the only things you can make out that the diver says is "oh for fuck sake"

they are lucky guys thats for sure

Even if i read the description of this vid, i still don't get it. What is happening? what would have happen if 40 seconds passed, would they explode?

[harrismagnum04]

basically yes after passing out and death

[harrismagnum04]

they where on the surface not a "minor glitch"

H O L Y F U C K! Diver's worst nightmare in a nutshell. Good guys though keeping their cool and saving themselves... otherwise the LSTs could have had a big ass strawberry jam situation to clean up.

@bat7j helium is used in the gas mix to purge out nitrogen in their blood - nitrogen is what causes the bends as it makes small bubbles in the blood stream wich kills you.

Why is the voice on the radio sounding like a cartoon character?

[pureintellectual]

god i was fucking scared! i heard about what happened and i thought this was a video of it

I like the way the diver had to be told to close the valves but when he started looking he was lost .....BELL CHECKS AWESOME !!! ............

Is there any actual footage of the Byford Dolphin disaster?

[geobenne]

Hey, It's Alvin and the chipmunks at 1:41

[LTDANMAN44]

what does blow yourselves down mean?

[masume21]

@Ironandtheshizzelz No, they would not explode, you'd have to have somthing like the byford dolphin incident for that to happen. They would have air bubbles form in their veins and they would die, but they would not explode.

@subsea777 Oxyhelium would be a type of strange cutting gas.

Heliox is a helium oxygen mixture. Helium is said 1st because it is the majority of the gas. its usually an 80- 10 ratio or maybe 86- 12, somewhere around there. It depends on the depth.

Its the same with Nitrox. Nitrogen is the dominant gas so we say the nitro part 1st.

Oxy-gen, heh, is what we call 51% oxygen and higher in an oxy nitrogen mixture. But thats confusing so we call it all Nitrox.
