When a vessel is required to have a powered driven fire pump, may the pump also be used as a bilge pump?

• A. No
• B. Yes
• C. Only in Emergencies
• D. Only for Small Vessels

Answer: (B)

The main idea is that a powered driven fire pump is a high-capacity pump whose purpose is to move water for firefighting, but its design also allows it to move water from other sources when needed. Because it can pump large volumes, you may use it to remove bilge water if the situation requires it, such as when the vessel is flooding or the dedicated bilge pump is unavailable. The key is to configure the system so the suction comes from the bilge and the discharge goes to a proper overboard path or to a suitable discharge line, without compromising firefighting capability. In practice, this means you can rely on the fire pump for bilge pumping in an emergency or as a supplementary measure, while ensuring you maintain ready access to its firefighting function when needed.
