RAFT suppression deliver low pressure water mist systems. Total flooding and local protection systems are installed in areas with high risk of fire.

Engine rooms are particularly vulnerable to fires due to the concentration of flammable materials and fire sources within a relatively confined space. Utilisation of low-pressure water mist safeguards machinery spaces and high-risk zones, rapidly extinguishing fires while minimising potential damage.

Engine room fire water mist RAFT suppression


In machinery spaces, low expansion foam is often employed to tackle flammable liquid fires, particularly in areas like bilges. However, over the recent years, water mist systems have emerged as the preferred choice for fire suppression. The properties of low-pressure water mist/FOG systems are environmentally friendly, while offering safe and secure operation.

At RAFT, our systems are meticulously designed to suit the interior constructions of all areas. The piping system undergoes careful calculations to align with both class and customer requirements. Operating within a system pressure range of 2 to 16 bar ensures minimal water damage while swiftly extinguishing potential fires. The effectiveness of low-pressure water mist technology as a fire suppression system has been thoroughly proven through significant reduction in water consumption and minimal power usage.

The water mist system for battery rooms can be delivered as a compact stand-alone system or integrated into the overall water mist control system.

The water mist will effectively control the fire through its cooling and oxygen-depleting effects, allowing for the ventilation of explosive and toxic gases during release.

Dedicated safety drills for battery related emergencies are necessary. Release of the fire extinguishing system has to be incorporated into safety routines early on.

According to DNV, nearly 2/3 of ship fires originate in the engine room, underscoring the critical significance of fire-extinguishing systems. And given that an engine room fire has the potential to incapacitate a ship, the importance of robust fire prevention and suppression measures cannot be overstated.

The fire triangle visualises the three elements required for igniting a fire: a combustible material, heat and oxygen. Water mist effectively eliminates two of these elements: heat and oxygen.

The concentration of oxygen near the fire area is reduced when small water droplets are evaporated into steam. This consumes energy from the heat radiation and prevents the fire from spreading to surrounding areas.
