🔍 Key Concepts

• 46 CFR fire protection requirements for cargo vessels of 1,500 GT and over • Minimum performance and pressure requirements for fire main pumps • Difference between capacity of pump and discharge piping area/arrangement

💭 Think About

• Check which option talks about the actual performance requirement of the fire pump at the most demanding locations on the ship. • Think about whether regulations are more focused on pump capacity and fire main effectiveness, or on how pumps may be shared with other systems. • Consider what it practically means for fire pumps to supply water to the highest and most remote hydrants on the vessel.

✅ Before You Answer

• Verify in 46 CFR that there is a specific pressure requirement at the highest fire outlets for cargo vessels. • Check whether the rules specify a relationship between fire pumps and bilge pump capacity, or if those are treated separately. • Confirm whether the regulations talk about the area of discharge piping from the pump, or mainly about flow and pressure performance.
