Sub MkIIIF for submarine escape and rescue


The Sub MkIIIF is designed to monitor the atmosphere within a submarine rescue vehicle or manned submersible.

Can Uzunsoy of Istanbul Shipyard says: "Your (Sub MKIIIF) analysers are very important for our ships (rescue and underwater systems abilities), you are a partner of valuable efforts"

The Sub MkIIIF consists of a central display which can be connected to up to 3 remote sensor modules or ‘REM’s’.

An SRV will typically consist of a pilot compartment, which is normally held at atmospheric pressure and a rescue compartment, which is designed to operate at hyperbaric pressures up to 6 Bara.

The Sub MkIIIF is specifically designed to provide accurate measurement of oxygen, carbon dioxide and pressure in both the pilot and hyperbaric rescue compartment.

The Sub MKIIIF is controlled by an operator console known as the ‘display control module’, or ‘DCM’. This displays measured parameters and alarm states sent from the remote sensor modules (REM) which are connected to it.

A REM 1 is designed to measure partial pressure oxygen, partial pressure carbon dioxide, and pressure.

A REM 2 is designed to measure temperature and humidity

If the measured parameters go outside normal operating limits there are two levels of audio-visual alarm activated, on both the DCM and the REM units. These alarms are announced by audible sounders and visible alerts (indicator lamps) on the front panel of each unit, which provide warning of gas and environment alarms, communication faults and calibration/general faults.

The DCM offers datalogging capability and can provide both relay outputs and 4–20mA outputs. The DCM is powered using 24 V DC. The REMs can be powered from either the DCM or a local supply. The DCM and REM units are connected together via a communications cable.

The REM units are designed to be calibrated and maintained by the user. A calibration check is recommended prior to deployment, or once every three months.

In most SRV configurations the DCM is installed in the pilot compartment with a REM 1, a second REM 1 is also installed in the rescue compartment. This provides the pilot & co-pilot with the ability to monitor and control the atmosphere in both compartments of the SRV.

In the event atmosphere monitoring is required for the Built in Breathing system (BIBS) Analox can offer a variant of the REM 1 which can fit into the BIBS pipework.
