[PSUBS-MAILIST] G.L. Rules Automation, Communication, Navigation, & locating equipment

[Alan James]

Hi Guys, here's more Bling for your submarine complements of G.L.
   Computer aided operating systems are permitted, details to be agreed with G.L.
there is a 43 page document Automation I-1-4 that is background reading for this.
   Any fault occurring in an automated system can't lead to a critical operating condition.
   Any inadmissible variations in  the operating parameters of the automated system
are to actuate visible & audible alarms.
   Automatic monitoring & automated functions have to be able to be switched to manual operation.
   The function of essential indicating lamps has to be check-able during operation.
Shutdown heating is recommended to prevent condensation inside electrical units (not sure what 
this involves)
   Forced ventilation of automation equipment is to be avoided if possible.
   Any cooling system for electronics needs to be monitored to ensure it is functioning.
   Potentiometers for equipment trimming & operating point setting that are accessible, need
to be able to be locked in position.
   The emergency power supply is to be monitored & failure is to be alarmed.
   There is a substantial list of electronics & monitoring equipment needed on the control stand.
It can be found section 12 B 2.1 & covers navigational & speed indicators, vehicle atmosphere,
electrical equipment, safety equipment/indicators, steering & control systems, sensors & actuators.
   An underwater telephone to the communicate with the support ship needs to have a minimum range 
of twice the nominal dive depth.
   The underwater telephone is to be fed from the emergency power supply & is to be capable of acting 
as a standby telephone system when the sub is on the surface.
  A signal system like flashing lights are needed to enable quick detection of the surfaced submarine.
Submersibles operating in areas of boat traffic need lights, signal devices & acoustic signals according
to the international regulations for prevention of collision at sea.
  Suitable position finding equipment for surface transit is required.
   Preferably you should paint your submarine orange yellow or red. (preferably yellow in honour of the 
beatles)
