CO2 Flooding System - Fixed Fire Fighting on Ships.
CO2 flooding system or central bank CO2 system is one of the common fixed fire fighting system installed on most of the ships. 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. Smothering action of CO2 extinguishes the fire thereby preventing spreading of fire to other parts of the ship. It consist of several CO2 cylinders located in a separate room, called CO2 room. These bottles contain CO2 in liquid state. When the fire in a protected space goes out of control or in a situation when the fire is not able to extinguish by local fire fighting media, CO2 flooding system comes into picture. CO2 from the bottles directed via common manifold, main valve and distribution pipe lines to nozzles through which it is released to the protected space for fire extinction. Due to safety reasons, the CO2 flooding system is manually released from a release cabinet located outside the protected space.
Carbon dioxide is the fire extinguising medium used in CO2 flooding system. It is an effective fire suppression agent applicable to a wide range of fire hazards. It has a high rate of expansion which allows it to work fast. When applied to a fire, CO2 provides a heavy blanket of gas that reduces the oxygen level to a point where combustion cannot occur. Since carbon dioxide is a gas, there is no clean up associated with a system discharge. CO2, a compound of carbon and oxygen, is a colorless gas which cause coughing to occur when inhaled. At higher concentrations it is acutely toxic. Low and high pressure CO2 is used for the fire protection of machinery spaces, pump rooms, cargo holds, paint stores and galley exhaust ventilation ducts on board ships.
There are several advantages for the CO2 as a fire fighting medium.
Density is 1.5 times higher than air. So CO2 settles down and displaces air.
It can be easily liquefied and bottled.
20% - 30% CO2 concentration extinguishes fire by smothering
Non-corrosive
Non- conductor of electricity
No residues left after application
No deterioration with age
Similarly there are some disadvantages also, such as:
CO2 is highly asphyxiating. 9% concentration causes unconsciousness within minutes
Very little cooling effect. So there is danger of re-ignition.
When discharged, solid CO2 particles present and generate sufficient static electricity to produce spark.
Explanation of CO2 Flooding System
As mentioned earlier CO2 flooding system floods the protected space under fire with carbon dioxide, which displaces air, thereby removing one leg of fire triangle for the extinction of fire. CO2 flooding system consist of main CO2 bottles, common manifold, master valve or distribution valve and distribution pipe lines with nozzles.
Main CO2 bottles contain carbon dioxide in liquid state with a pressure of 56 bar at 20 degree Celsius. Pressure of CO2 at 25 and 30 degree Celsius are 64 bar and 71 bar respectively. So it is important to keep the temperature of CO2 bottles low for limiting the pressure inside bottles. CO2 from the main bottle is released by a ‘CO2 release cabinet’ as shown in the figure. As soon as the release cabinet door is opened, a micro switch is activated. The micro switch will ensure the activation of CO2 warning alarms and ventilation shut off. CO2 release cabinet or release box consist of two pilot CO2 cylinders or bottles containing CO2 gas inside. The pressure of CO2 inside these pilot bottles is same as that of main CO2 bottles. Only quantity of gas is different. For releasing CO2 to the protected space, one of the pilot bottle valve is opened. Now CO2 reaches two valves marked 1 and 2. First valve 1 is to be opened. Then CO2 passes through a non return valve and opens pneumatically operated master valve. Now master valve is opened. Next, open valve 2 in the release cabinet, which supply CO2 to main CO2 bottle head assembly through a non return valve and ‘time delay unit’. Function of the time delay unit is explained below. Head assembly consist of a pressure operated cylinder valve. This pressure operated cylinder valve prevents CO2 from bottle coming to the common manifold. As CO2 reaches the head assembly from pilot bottle, pneumatic actuator in the head moves and opens the pressure operated cylinder valve. Then CO2 from main bottle escapes to the common manifold via non return valve as shown. Each of the main CO2 cylinder have a head assembly and non return valve. The pilot CO2 line is connected to all these heads. All the CO2 from the main bottles now release to common manifold. Since the master valve is already open before, CO2 from manifold is released to the protected space through distribution pipe lines and nozzles.

[@Rammstein56]

Co2 leaves no traces, it vaporizes Co2 is stored in high pressure cylinder containing 45 kilo of Co2, although nowadays some have larger cylinders. Co2 does not extinguish a fire, it simply lowers the oxygen level, killing a fire. The time the alarm sounds and the beacon flashes is the time-delay unit which automatically delays the total flooding of Co2 so the crew can exit the engine room and not die of suffication. A Co2 release total flooding makes a hell of a noise. There is no need for a live test like this, during the bi annual maintenance the release is imulated and the extinguishing lines are blown with compressed air wjich is a mandatory procedure as well as testing of the release system, the alarms and the main valve. Amd the former used Halon 1301 was avery effective fire extinguishant jowever it was bad for,the ozone layer and therefore banned. Modern engine rooms also often have a high pressure water mist system as a back up.

[@Chris-ml8hs]

Would have really sucked for all involved if it dumped a halon system

[@davebloggs]

we used to use BCF or Halon, 9 cylinders dumped after 9 seconds final alarm. engines stop real fast,

[@macbook802]

That would be a hell of a whippet

[@terrycollins6392]

Mmmmmmm that could be answered by a “That’s ok” but also another point “They have to be tested regularly” and sometimes like when you work on a ship or in a supermarket the boss or manager will just press the smoke/fire alarm system without any notice and it really does keep you on your toes and also shows up any faults in staff’s attitude. I remember when a sloppy department manager was removed from his position with quite a large pay cut when he was heard saying that “It was only a test” and took hardly any notice until the manager of the store wanted to know why he was still putting out stock while the fire alarm was still going off🤷‍♂️🤔he didn’t last much longer

[@lowandslow3939]

No. Completely different on a boat (yacht) This type of testing is only done while the boat is in a refit and has contracted a company ashore to refill the very large tanks that contain CO2. This has to be done immediately so as not to leave the vessel without the protection of this system. The delay is there to allow crew to evacuate the engine room before the gas is released. Not only is it dangerously cold, (frostbite) but all oxygen is replaced by CO2. That would kill anyone inside that space very quickly. This is a very well controlled and expensive test, not some random drill.

[@brandonobaza8610]

Can't imagine it would damage the engines. Maybe some flooding, depending on how many unignited injection events happened before they stopped.

[@peternoble5395]

I should have been clearer - CO2 is a 1 shot system- this requires the engine room to be as air tight as possible - all fans off/doors and hatches closed- if the engine or even an air compressor is running it will suck the co2 out of the engine room- the injection capability will be lost immediately and if it is a real fire you will have lost all cooling to save the equipment

[@nickauclair1477]

Some of these recent boat fires might have been caused by a lithium fire. It's devastating.

[@USA-GreedyMenOfNoIntegrity]

A fireproof battery compartment, good monitoring system, power dosconnects, CO2 and water will surely help minimize the damages.

[@JBF-GST-Tanda]

For lithium battery fires the best way is to totally quench and drench and drown it rapidly with enormous amount of water or foam so that all the heat from crazy exothermic reaction could be absorbed. Don't attempt to save the device itself, or you'll only damage more stuff surrounding it.

We used to pop the fire suppression system in tanks and amtracs just to mess with the crews. We had to periodically test some of them, not our fault there was always somebody in there when you pulled the handle. It didn't hurt to be faster than whoever was in the vehicle though, they didn't tend to think it was as funny as the guy that pulled the handle.
