Hi guys
I'm researching a feature film script and I need some advice on a specific scenario...
I need to transfer two people - with no gear - from a pressurized vessel (like a mini submarine) to a wet diving bell in an emergency.
I want it to be as realistic as possible, but not necessarily as safe as possible. As with most movies based on tension, the odds of them transferring safely have to be 50/50.
1. At what depth below surface could somebody conceivably exit a pressurized vessel with no gear and swim a short distance to a wet diving bell?
2. Would a wet diving bell be believable at this same risky depth?
3. At 50/50 odds, what kind of physiological effects could one expect in attempting this?
4. Would those effects, say sustained for a minute or two swim between pressurized spaces, even be survivable with a wet bell, or would the pressure be too much and require a hyperbaric dry bell?
I'd prefer they can step out on to a ship deck upon surfacing without life-threatening complications, but they don't necessarily have to be walking in perfect health straight away.
Any help would be hugely appreciated and I'm open to hearing suggestions or complications I may not have considered.
Thanks, guys
Pete
