Routine atmosphere monitoring
As a supplier of bespoke solutions for submarine atmosphere monitoring we understand the complexities of the environment in terms of pressure, temperature and humidity variations. Requirements may vary between types of submarine and different solutions are offered for diesel electric, air-independent propulsion (AIP) and nuclear boats. The permissible level of gas on a submarine may also vary from nation to nation.
Analox Military Systems understands these issues and can offer a number of fixed and portable atmosphere monitoring solutions, as well as a tailored bespoke design service.
Centralised atmosphere analyser
Hydrogen (H2) monitoring
Batteries on diesel-electric submarines release H2 into the atmosphere as a by-product of the charging process.
H2 can be removed from the atmosphere by the boat snorkelling, or alternatively, by burning the H2 - this turns it into carbon dioxide which can be scrubbed out of the atmosphere.
Small amounts of hydrogen can be explosive, which can be catastrophic in a confined space such as a submarine. This means H2 monitoring in a submarine is essential, and any sensors used need to be ATEX approved for use in a potentially explosive atmosphere.Analox Military Systems offer stand-alone hydrogen sensors as well as a distributed sensor network which can be used to measure a range of gases around the submarine.
Distributed sensor network
- Flexible system architecture, providing adaptability throughout the boat's operational life
- Sensors located in the area where the gas poses a direct risk, providing real-time alerts to hazards in the area they occur
- Designed to be maintained in destination country, providing increased availability of the system
Carbon monoxide (CO) monitoring
CO monitoring in the submarine environment requires a different technology than that used in off-the-shelf carbon monoxide detectors. Standard electrochemical sensors are extremely cross-sensitive to hydrogen, making them unsuitable for use in the submarine environment. Analox Military System's solution for routine CO monitoring is the COSAMS which uses a selective infrared sensor which eliminates cross-sensitivity to other gases likely to be present within the submarine atmosphere.
