<h3><span style="COLOR:#0000ff;">Exercise Sorbet Royal</span></h3>
<div>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.</div><br clear="none"><br clear="none">Vbr Carsten <br clear="none"><br clear="none"><div class="qtdSeparateBR"><br><br></div><div class="yiv8070239393yqt2157622903" id="yiv8070239393yqtfd16161"><br clear="none">"Hugh Fulton via
