The new SOLAS regulation XI-1.7 calls for all Ships over 500 tons to carry compliant confined space gas detection equipment.
SOLAS compliant gas detection should detect Oxygen (O2), Flammable gases (CH4 ir HC), Hydrogen Sulphide (H2S), Carbon Monoxide (CO), have sample draw capability over 10 hours operation and be Explosion Proof: Intrinsically safe ( ATEX in Europe)
The International Convention for the Safety of Life at Sea (SOLAS) is an international treaty that sets minimum safety standards in the construction, equipment and operation of merchant ships.
SOLAS in it's successive forms is generally regarded as the most important of all international treaties concerning the safety of merchant ships.
Riken Keiki offers fully compliant solutions for robust frequent use and also for occasional use compliance purposes.

Plant rooms are often situated underground. This is by design to save space or by virtue of being built into existing basements or chambers. Underground Plant Rooms often contain an array of machinery such as Pumps, Boilers, Sprinkler Systems or Generators.View Story

For more information about positioning fixed gas detectors, further guidance can be found in the new Gas Mapping Standard BS 60080 (Fire and Gas Mapping ), IEC 60079-29-2 (Explosive atmospheres – Part 29-2: Gas detectors – Selection, installation, use and maintenance of detectors for flammable gases and oxygen), and also EN 45544-4 (Workplace atmospheres – Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours. Guide for selection, installation, use and maintenance.). Additionally, The CoGDEM ( Council of Gas Detection and Enviromental Monitoring ) Guide to Gas Detection is an excellent general user guide for Gas Detection, written by those in the industry.View Story
Catalytic combustion sensors are the standard method for detecting combustible gases including Hydrogen, however in order to operate a minimum of about 10% Oxygen needs to be present. IR sensors are a good solution to this problem for measuring most combustible gases in an inert environment where O2 levels are below 10% volume but IR sensors cannot detect Hydrogen.
Riken Keiki offers several solutions around this problem.View Story
