<H3><SPAN style="COLOR: #0000ff">Exercise Sorbet Royal</SPAN></H3>
<P>A NATO exercise, Sorbet Royal in May 2002 (Cohen 2003), demonstrated
the
effectiveness of the system when four crewmembers and five others from
Denmark,
the UK and USA, both men and women, donned SEIE suits to simulate an
escape from
the Swedish submarine <EM>Vastergotland</EM>, down 115 feet off the
coast of
Denmark. The submarine’s escape tower had a four to six minutes recycle
time,
(determined chiefly the time it takes to drain the flooded tower) but
they used
a 15-minute interval for this demonstration. The exercise worked as
briefed,
with 18 seconds required for the pressure equalisation phase, the
pressure
doubling roughly every four seconds or so, and nine seconds required for
the
ascent. Rescue units, including a decompression chamber, were waiting in
smooth
seas on the surface.</P><BR><BR>Vbr Carsten <BR><BR><BR>"Hugh Fulton via

<BR>> <BR>> <BR>> <BR>> Hi Guys,My
two<BR>> Steinke hoods turned up. Made in USA 1982. Still in good
condition. I <BR>> have looked at the escape training
video which was great. Questions. It is<BR>> obvious you need
a fill hose for the initial fill at depth prior to<BR>> opening the
hatch. i.e. if you are at 10 atmospheres depth then you
need<BR>> to fill it with 10 atmospheres (bar) pressurised air. 1.
How many of you<BR>> are adding a Steinke fill hose with an Aro
coupling for this purpose. 2.<BR>> Breathing this will give
you narcosis. So is it better to have 2 bottles<BR>> of mixed
gas for this purpose? One for 8-15 bar depth escapes and one
for<BR>> 16-25 bar depth escapes. Air could be used up to 8
bar.3. What are the<BR>> mixes recommended for these depths to
prevent narcosis as it could take 5<BR>> minutes to pressurise and
escape. Chs Hugh.<BR>> <BR>> <BR>> <BR>> __________
