A Submarine Rescue Vehicle (SRV) is used to rescue surviving submariners from a
DISSUB, in order to maximize their chances of survival they need to be
transferred into the SRV and subsequently into the decompression chamber,
at the same pressure they have been exposed to on board the DISSUB.
As a result the SRV typically consists of 2 compartments; a pilot compartment,
and a rescue compartment. The pilot compartment is typically held at atmospheric
pressure, whereas the pressure in the rescue compartment can be changed to
match the pressure in the DISSUB. There is therefore, a need for hyperbaric
monitoring inside the rescue compartment.
The Analox Sub MkIIF offers the base platform on which this monitoring can be done.
It provides continuous real time information on the levels of Carbon Dioxide (CO2), Oxygen (O2),
pressure, temperature and humidity in the rescue compartment, and can be configured
for maximum pressures up to 60 BarA, although most systems tend to operate up to 10 Bar A.
The Sub MkIIF consists of a main control panel and up to 2 Remote Sensor
Blocks (REMS). The control panel is located in the pilot compartment and
provides the primary user interface used to set alarms, calibrate the sensors,
download data, and control the relay and mA outputs, it also provides power to the Remote Sensor Blocks.
Two REM’s are available, the REM 1 contains the sensors for O2, CO2 and
pressure, and is located inside the rescue compartment, where it provides
a local partial pressure readout of atmospheric conditions.
The REM 2 provides monitoring of temperature and humidity, is optional,
and is also located in the rescue compartment.
