🔍 Key Concepts

• Fire main system layout from the pump discharge to the hydrants/nozzles • Purpose and normal location of a pressure gauge, strainer, reduction valve, and international shore connection • Regulatory intent: monitoring vs protecting equipment vs connecting to shore supply

💭 Think About

• Think about what information the crew needs to see immediately as water leaves the fire pump and enters the fire main. • Which device must sense or act on the water conditions (pressure/cleanliness/connection) right after the pump, rather than farther out in the piping? • For each option, ask yourself: is this usually installed near hydrants, at inlets, on suction side, or specifically right at the discharge?

✅ Before You Answer

• Be clear on the difference between suction side and discharge side of a pump. • Recall where an international shore connection is normally fitted on board and why. • Consider which item is needed to continuously monitor pump performance and system pressure as soon as water leaves the pump.
