RE: [PSUBS-MAILIST] concrete submarine - something big -

[clientes@tolimared.com]

Hi Carsten, Jay,

Yes a diver lockout for deep diving submarine makes little sense 

Saturation deep diving with work capability means weeks under saturation this is
a saturation sistem of ship size where the lockout is smallest part it needs
living chamber transfer chamber, rescue chamber, docking sistems, hot water for
the suits diver support back up winches gas mixing and control facilities
kitchen to feed the hungy pack... etc. etc. 

So this brings us back to the basic question - how you get things done.
The answer for deep diving - keep it 1atm - so we are talking about Jim Suit or ROV.

Each of those needs a BASE from where it can be deployed. And this could be a
submarine - advantage no spooling of cable, quiet water and controlled
conditions at all time.

But it needs BASE ship capacity - sufficient living and working space. So we
talk hundreds of tons at least when Carsten says "big" this means "big" compared
to his 70 tonner at work.

Limit is money - how much submarine we can get for a budget - concrete opens new
horizon here - not only for drilling operations - for privatly owned subs too.

Reagards,
Wilfried
