FIRE STATIONS

The fire stations are part of the raw water firefighting system. The fire stations make pressurized firefighting

water available to multiple locations on the vessel. The fire stations are capable of shooting 70 gallons (265 liters)

of water per minute (in a solid stream) approximately 75 feet (23 meters) when pressurized to 100 PSI (6.9 bar).

The technical characteristics of the fire stations are contained in table 10.

DIESEL ENGINE-DRIVEN FIREFIGHTING PUMP

The diesel engine-driven firefighting pump pressurizes the exterior firefighting system. It is located in AMS 1 and

draws raw water from the sea chest through a simplex strainer to prevent clogging when pressurizing the external

firefighting system. The pump is a horizontal centrifugal pump with a maximum output of 1,000 gal/min

(3,785 L/min) at 170 PSI (11.7 bar).

The technical characteristics of the diesel engine-driven firefighting pump are contained in table 11.
