Co2 Fixed Fire Fighting System On Ship

One of the most commonly used fire extinguishing agents in ships engine rooms is carbon dioxide co 2.

Co2 fixed fire fighting system on ship.

In case of a major engine room fire on merchant ships co2 fixed fire extinguishing system is the most common method used for fire fighting. Several minutes may be required before all necessary preparations have been completed and the co2 halons can be released. It is imperative that the co2 bottles are strong and sturdy due to the high internal pressure they are going to withstand. A fixed type of co2 fire fighting system includes a large no of co2 bottles arranged together.

Co2 the modern alternative considering that halon systems were banned because of their supposed ozone depleting properties it seems a little ironic that the more common replacement other than novec 1230 is carbon dioxide co2 which is also highly criticised as a modern pollutant. Its similar equivalent used in shore based industries or institutions is known as the co2 fire suppression system. In the majority of the ships the fixed fire extinguishing system to the engine room is co2 halons. Fixed fire fighting systems available.

The central bank or co2 flooding system is the most commonly used fixed fire fighting system onboard a vessel. For this reason the bottles are made from solid drawn steel and are also hydraulically tested upto 228 bars prior to installation. Smothering action of co2 extinguishes the fire thereby preventing spreading of fire to other parts of the ship. This system is mainly used for large areas on ships such as cargo holds or machinery spaces of engine room where fighting fire gets difficult due to extended spaces and fire intensity.

This is a once off shot and to have maximum effect all ventilation fans must be stopped and the fire flaps closed. It releases carbon dioxide co2 in bulk quantity to a protected space such as engine room cargo hold purifier room pump room etc under fire. The chief engineer of the ship is responsible for operating the co2 extinguishing system after taking all precautionary measures regarding handling of engine room machinery. That is basically the same thing but with lesser co2 bottles tanks.
