What type of fire-fighting system is commonly found on tankers?

A foam-based fire-fighting system is particularly effective on tankers due to the nature of the cargo they carry, which often includes combustible liquids that can produce flammable vapors. Foam suppresses fire by creating a blanket that cuts off the oxygen supply needed for combustion, which is crucial when dealing with fuels and other hazardous materials typically found on tankers.

Foam systems can be deployed quickly and cover large areas, making them suitable for the vast deck space of tankers as well as for protecting tank openings to prevent flammable vapors from igniting. This type of system also has the ability to cool the surfaces around the fire, further aiding in fire control and minimizing the risk of re-ignition.

While other systems, including dry powder, CO2 suppression, and water spray systems, have their specific applications and are essential in certain scenarios, foam systems are generally preferred for their efficacy against liquid fuel fires and their versatility in addressing various fire challenges encountered on tankers.
