Description

Foam Mobile System

KEY FEATURES
The low expansion foam quickly blankets the fire and prevents further outbreak
A balanced pressure proportioner guarantees reliable foam mixing from 1-3 % ratio
Foam monitors and portable applicators can be used individually or in conjunction
Fixed foam monitors are used to fight fire from a predetermined safe distance, while portable applicators and nozzles cover shadow areas not reachable by the monitors
Sturdy and compact foam monitors are adjustable and can be used in two modes: jet or fog
It comes in two operating options: manual or remotely controlled with hydraulics

TECHNICAL INFORMATION
SYSTEM DESCRIPTION AND CONFIGURATION
The Survitec Deck Foam Fire Extinguishing system consists of a fibre glass foam tank, foam pump, proportioner, sturdy and compact foam monitors and portable foam applicators or foam spray nozzles meeting the latest IMO regulations. The system can be delivered as either a central system or independent modular skid units. In a modular design, foam tank, foam pump, proportioner, valves and control panels can be delivered on skid units. All components are constructed in corrosion
resistant materials. The control station is suitably located outside the protected area, adjacent to the areas protected and readily accessible and operable in the event of fire.
On deck
The monitors are located along the deck, with two monitors mounted on the poop deck. They can be operated manually or remote hydraulically.The number and spacing of the monitors, foam tank capacity and system pressure/capacity is dependent upon vessel type and the area to be protected. For maximum effectiveness, a balanced pressure proportioner guarantees reliable foam mixing. Foam applicators are provided for flexibility during fire fighting on deck areas and to cover areas shielded from monitors.
In machinery spaces
In machinery spaces where a fixed low expansion foam system is fitted in addition to a total flooding system, the system discharges foam through fixed foam spray nozzles. In addition, inductor type portable foam applicators are required.
On helidecks
Foam Mobile System Survitec fixed low expansion foam system can be used for any size of helidecks and helicopter landing areas. It can be a combination of deck integrated pop-up nozzles or fixed foam monitors. In addition, the system consists of hose reels fitted with foam-making branch pipe and non-collapsible hose.
Activation of the system
System is activated from control panel. It can be either an automatically controlled or a manually operated system. For an automatic system two alternatives are available: electric controlled and hydraulic controlled. In case of electric controlled system, valves are electrically actuated, while foam monitors are manually operated. A hydraulically controlled system requires a hydraulic power pack, which is usually installed in the machinery space. Valves and monitors are then hydraulically controlled from a remote location with joystick connected to the control cabinet.
Extinguishing fire using Deck Foam
The fire fighting foam concentrate is a collection of bubbles that consists of water, air and special chemicals. The bubbles float on top of flammable liquids and work to extinguish flammable liquid fires.
Fire fighting foam extinguishing mechanism:
The foam blankets on the fuel surface smothering the fi re.
The foam blanket separates the flames/ignition source from the fuel surface.
The foam cools the fuel and any adjacent metal surfaces.
The foam blanket suppresses the release of flammable vapours that can be mixed with air.
Survitec Deck Foam system uses either fluoroprotein or synthetic foam concentrates. Depending on application, it can be alcohol resistant for polar solvent fi res or regular ones for hydrocarbon fi res. Foam concentrates offered are MED, IMO MSC.1/Circ.1312 approved. Some foam liquids are HOCNF and ICAO approved. Based on extreme applications, foam concentrates can be freeze protected down to -45 °C.
