[PSUBS-MAILIST] FW: Escape with Steinke Hoods.

Fri Jan 16 16:04:49 EST 2015

Carsten,I think G.L. consider that if you keep to all their rules ie. support boat,communication etc, you won't have need for a flood valve becauseyou will be rescued.Also they are an insurance agency & if you are stuck in your sub on 
the bottom in an unknown location, then you can't make an insurance claim:)If parachutes were the size of flood valves then everyone would have one.Alan

E-Mail Software 6.0Maybe because GL not operate submarines..   
Maybe theyassume that the operators are not expirence scuba divers. 

SL require flood valve and over pressure valves.. 
.. but theresupervisor operates submarines and are scuba diver.

On the other side:
Nobody from us wear ever a parachute if he climb into a passenger aircraft.. 
Maybe I should do on my next trip - just to see thefaces of the stewardesses.. 
The airlines belive that there are better way toget the passangers home.

HiHugh,the twenty minuteswas a response to Carsten. I guess he needs that for hissub.G.L. don't requirea flood valve. I questioned them about this & they just relyon other initiativesto get the sub up.A pity if you werein 30ft of water & couldn't be found.Alan

Subject: Re:[PSUBS-MAILIST] FW: Escape with SteinkeHoods.  If it takes 20 minutes to flood the submarine, then the first 10minuteswill half fill the sub, at which point you will be at the equivalentof 33ft.So no problem of decompression sickness to this stage. It justgetsexponentially worse as you continue to flood & the pressuredifferentialbetween inside & outside gets less making the fillingslower.As Phil says, you need to add air for the lastpart.One of my worries is that you will blow your ear drumbs with nocontrolof the flood valve. Would be really good to have some sort of simulator program thattoldyou what was happening at various depths & what the dangersofnarcosis & decompression sickness were.Alan  From: "Carsten Standfuß" via Personal_Submersibles" <personal_submersibles at psubs.org>

If you need 20 Minutes to flood thesubmarine in 100 meter deep (300 feet) it do not matter any more whichgas you have in the hood for 1-2 minutes. 
You will getdecompression illness or dead anyway. 

The compression time in the submarine has to be short aspossible.
A big flood valve help. Releaseing the rest ofyou gas from the boats-bottles at the end of the flooding time into yourflood cpompartment to equalize the pressure help also. 

One drawback of the Steinke Hood is thatit is even as expirence sportdiver nearly impossible to stop the unit at9 or 6 or 3 m deep for a decompression stop.

another from the internet:
Exercise Sorbet Royal
A NATO exercise, Sorbet Royal in May 2002 (Cohen 2003), demonstratedthe effectiveness of the system when four crewmembers and five othersfrom Denmark, the UK and USA, both men and women, donned SEIE suits tosimulate an escape from the Swedish submarine Vastergotland, down 115 feet off the coast of Denmark. Thesubmarines escape tower had a four to six minutes recycle time,(determined chiefly the time it takes to drain the flooded tower) butthey used a 15-minute interval for this demonstration. The exerciseworked as briefed, with 18 seconds required for the pressureequalisation phase, the pressure doubling roughly every four seconds orso, and nine seconds required for the ascent. Rescue units, including adecompression chamber, were waiting in smooth seas on thesurface.
