Advanced Integrated SystemsCustomized special air systems
DMR has constructed a number of special systems however in 2009 we patents our ventilation system now used in custom built plans where the danger due to the presence of flammable or explosive gas is present.
The system is called “Temporary Refuge” and allows for all personnel on an oil platform, in the work areas of the platform or the service craft to have a Safe Room (a large room, such as the canteen, can be easily transformed into a safe room for the personnel).
PRESENCE OFPOISONOUS and/or FLAMABLE GASES IN THE ENVIRONMENT PUT OPERATORS IN SAFE CONDITION AND ALLOWS THE USE OF COMPRESSED NITROX INSTEAD OF COMPRESSED OXYGEN THEREBY INCREASING AVAILABILITY OF TR MODULE AND REDUCES OPERATION RISK
PRESENCE OFPOISONOUS and/or FLAMMABLE GASES IN THE ENVIRONMENT FORCES TO PRESSURIZATION and TO FILL WITH INERT GAS SPARKING SOURCES THE USE OF ENGINES EXAUST SIMPLIFIES OPERATION
OPERATION IN FLAMMABLE ENVIRONMENT (IMPOSSIBILITY TO USE EXTERNAL AIR) FORCES TO OPERATION WITH STORED COMPRESSED AIR (SEE AIP FOR SUBMARINES) THE USE OF COMPRESSED NITROX INCREASES THE OPERATION TIME WITHPOUT INCREASING OPERATIONAL RISK
The Temporary Refuge provides protection from fire, resistance to flashes of heat caused by the burning of possible mixes of combustible gases and creates survival conditions and adequate protection for personnel by supplying clean air, medical oxygen and air filtration to remove the carbon dioxide generated bythe respiration of those inside the environment.
