🔍 Key Concepts

• SOLAS fire protection standards for cargo ships on international voyages • Minimum number and power source of fire pumps on cargo vessels • Standard fire hose length and diameter requirements for interior vs. exterior locations

💭 Think About

• First, think about what SOLAS and 46 CFR generally require for the minimum number of fire pumps on a cargo ship of this size on international voyages. Would a single pump ever be acceptable? • Consider where 50-foot, 1 1/2 inch hoses are typically allowed: are shorter hoses more common inside machinery/accommodation spaces, or on open decks? • For the piping question, ask yourself: what is the effect on discharge pressure if the piping area is smaller than the pump discharge area versus larger? Which condition produces higher back pressure?

✅ Before You Answer

• Verify in regulations whether two independently driven fire pumps are a basic minimum for cargo ships on international voyages around 2000+ gross tons. • Check the typical standard fire hose length used on cargo vessels (often 50 ft) and where 1 1/2 inch hoses are permitted or preferred. • Confirm the basic hydraulics principle: how does total downstream pipe cross-sectional area compared to the pump outlet area affect pressure and flow?

Question 1 of 20

Which of the following statements is correct concerning fire main system details used aboard 2500 gross ton cargo vessels on international voyages?

The vessel must be equipped with a minimum of two independently driven fire pumps.

Fifty foot length hoses of 1 1/2 inch diameter may be used in exterior locations on the vessel.

The total area of the pipes leading from a fire pump must be more than the discharge area of the pump to avoid an excessive back pressure buildup (discharge head).

All of the above.
