What is the function of fire main systems aboard a ship?

The primary function of fire main systems aboard a ship is to supply water for firefighting. This system plays a critical role in ensuring the safety of the ship and its crew by providing an accessible and reliable source of pressurized water to combat fires that may occur in different areas of the vessel. Fire mains are typically used to connect to fire pumps which can draw sea water or other sources, and they distribute that water through a network of pipes to various firefighting stations throughout the ship.

These stations are equipped with hoses and nozzles that allow crew members to effectively extinguish flames and prevent catastrophic damage during a fire emergency. The reliability of fire main systems is vital, as fire represents one of the most significant hazards at sea. Therefore, ships are designed with robust fire main systems that can deliver a substantial water supply under pressure to tackle fires wherever they may occur.

While drinking water, cooling systems, and ballast management are important functions on a ship, they fall under separate systems specifically designed for those purposes, and do not overlap with the dedicated fire main system responsible for firefighting.
