a day at <strong>the</strong> SETT<br />
Dan Koo Mo Shan<br />
The Royal Navy’s <strong>Sub</strong>marine Escape Training<br />
Tank (SETT) at Gosport, was built in <strong>the</strong> 1940’s<br />
to provide a site where submarine escape<br />
training, practice and drills could be carried out<br />
in a c<strong>on</strong>trolled and safe envir<strong>on</strong>ment. The tank<br />
is housed in a ten storey tower, and measures<br />
just five meters wide but 30 metres deep!<br />
briefing<br />
The day started with security<br />
checks and <strong>the</strong> issuing of<br />
Royal Navy passes and <strong>the</strong>n <strong>the</strong><br />
mandatory safety briefing, which<br />
I nearly missed being Mr. Late.<br />
<strong>the</strong> tank<br />
Briefing over, it was time for a<br />
proper glimpse of <strong>the</strong> tank. Unlike<br />
<strong>the</strong> normal users of <strong>the</strong> tank who are<br />
pushed out <strong>the</strong> airlock at <strong>the</strong> base<br />
of <strong>the</strong> tank to free ascend to <strong>the</strong><br />
surface, I would be entering from<br />
<strong>the</strong> top. This meant hauling all our<br />
scuba gear to <strong>the</strong> 10th floor... thank<br />
goodness for lifts!<br />
The water in <strong>the</strong> tank is crystal<br />
clear and, when looking down, I<br />
could <strong>on</strong>ly compare <strong>the</strong> feeling to<br />
looking down a l<strong>on</strong>g lift shaft. But<br />
this was given an odd twist by <strong>the</strong><br />
feeling of <strong>the</strong> warm water which<br />
came right to <strong>the</strong> lip of <strong>the</strong> tank,<br />
gently lapping unexpectedly over<br />
my face.<br />
<strong>the</strong> dive plan<br />
The plan was to dive in buddy<br />
pairs, with a bottom time of fifteen<br />
minutes, plus a safety stop. A<br />
routine was quickly established so<br />
that <strong>the</strong>re was always <strong>on</strong>e buddy<br />
pair heading for <strong>the</strong> bottom whilst<br />
<strong>the</strong> previous pair were ascending.<br />
into <strong>the</strong> tank<br />
I was diving with Pete Custers<strong>on</strong><br />
and it was time to enter <strong>the</strong> tank,<br />
by ladder to reduce spillage.<br />
I wish all dives could be like<br />
this... it was like entering a bath as<br />
<strong>the</strong> water temperature was a steady<br />
33 degrees.<br />
Those who have dived with me<br />
will know of my BCD’s c<strong>on</strong>stant<br />
struggle to free itself of anything<br />
attached to it, ei<strong>the</strong>r cylinders or<br />
weights. Thanks to Martin Forde,<br />
I managed <strong>the</strong> dive without any<br />
cylinder slippage but I maintained<br />
my reputati<strong>on</strong> as my cylinder’s boot<br />
did fall off <strong>on</strong> entry!<br />
down we go<br />
I had c<strong>on</strong>sidered a fast descent, like<br />
a slow moti<strong>on</strong> skydiver, but as I was<br />
worried about clearing my ears, and<br />
Pete was faffing with his new wing,<br />
<strong>the</strong> decent was nice and slow.<br />
At <strong>the</strong> bottom my dive computer<br />
registered 27 metres and it was time<br />
to look around <strong>the</strong> bottom of tank<br />
which was largely taken up by <strong>the</strong><br />
main airlock/hatch.<br />
After ten minutes, without <strong>the</strong>
