| Hope this helps...Vickers SEL would be a good place to start, as they can pass you on to the Naval Architecture Department. Be careful though...Depending on what you're modelling certain information is still classified.
I can tell you this though.
Watertight doors and hatches on all HM Ships have either X,Y, or Z codes.
X doors were usually left open most times and closed during higher alert (zulu-bravo, or zulu-alpha state), this is to protect The Citadel. The ship's steering, control and fighting systems had to be gas-tight with positive pressure air systems in place. The reason why HMS Sheffield and HMS Antelope were unsavable was partly because of fire and communications failures.
Y doors were closed generally but you had access. Again, this changed if the Ship was on alert for the same reasons, then you had to have permission to access first.
Z doors were always closed and you had to have permission to enter a restricted part of the ship. During alert...phone first.
What Ship are you going to model?
Best wishes and good luck...jules |
