Re: [PSUBS-MAILIST] acrylic dome escape pod question for Carsten.

[Carsten Standfuss <Merlinsub@t-online.de>]

Hi Carsten.
 
Are you saying the only thing holding the dome in place is a rubber
holder (or with Peppers the bayonet lock) and the water pressure is 
all that is holding the dome in place against the rubber holder? If this
is true, how would you release the dome without first counteracting the
outside water pressure against the dome if you had exhausted all your
interior air without letting water in to pressurize the remaining air?
 
If I am intrepreting this correctly, wouldn't this require you to either
have enough interior air left to release the dome off, or else you would
have to
partially flood the hull to pressurize the remaining air in order for
the dome to release?
 
Or did I totally misunderstand you? Thanks Carsten.
 
Kindest Regards,
Bill Akins.


Hi Bill.. 

Proposal for an emergency procedure to get 
out of a boat with top side dome: 

- Open the holder for the dome -outside pressure will hold him in place. 
- if nessesary remove hinges holder bolts. 
- Open the big flood vale in the bottom area
- if abvailable open also the remains of compressed storage air to
the    cabin to speed up the compression process. 
- if inside and outside pressure is equal the dome will lift away -
make   sure that your hands on the two inside handles of the dome and
you head  is inside the dome bubble. 
- This parachute dome will lift you with a high spped to the surface -
make sure that you breath normaly in and out. Make sure that the design
of your flood vale is that way that the flooding get quick - so that you
have not to much time to stay under higher pressure - because of the
decompression tickness.. 

best regards Carsten
