Glossary Term
Fire Pump
The fire pump supplies the water pressure and flow needed for the yacht’s fire main and hydrants. On a superyacht, the term usually refers to the main power-driven fire pump and, where required, the additional independent or emergency fire pump arrangement that allows firefighting water to remain available if one space or one power source is lost.
The code focus is performance under fire conditions, not just pump presence. The Red Ensign Group Yacht Code sets capacity requirements for the main pump, requires the second pump to have substantial output and its own external sea connection, and requires centrifugal fire pumps to have non-return valves on the connection to the fire main. Survey guidance also checks whether each fire pump, including the emergency fire pump, can operate separately so the required water jets can be produced simultaneously from different hydrants.
On refit or troubleshooting work, fire-pump questions usually involve priming reliability, suction integrity, starter and control condition, non-return valve function, pump-room location, and actual discharge pressure at the hydrants. A fire pump that runs but cannot support the required hose performance is a defective fire service system. Much of the technical work falls within mechanical and hydraulic service together with verification of the wider fire-main arrangement.
