Which statement is TRUE concerning cargo hose on tank barges?

🔍 Key Concepts

• Cargo hose pressure rating requirements for tank barges • Meaning of static head vs shut-off head of a cargo pump • Where cargo hose design/maintenance standards appear in 46 CFR

💭 Think About

• Think about the worst pressure the cargo hose might realistically see during loading or discharging. Which condition creates the maximum pressure in the hose? • How does the pump behave when valves are closed and liquid is not moving? What is that condition called, and what does it do to pressure? • Look carefully at which answers mention a fixed psi value only versus those that relate hose strength to pump characteristics. Which seems more consistent with how regulations are usually written?

✅ Before You Answer

• Verify how shut-off head is defined in relation to pump discharge pressure. • Check if the regulation ties the hose rating to the maximum discharge pressure of the pump system, not just a minimum psi. • Confirm whether the rule adds or subtracts static head from the shut-off head when determining the hose pressure requirement.

Which statement is TRUE concerning cargo hose on tank barges?

Cargo hose must be able to withstand the static head of the cargo pump but no less than 100 psi.

Cargo hose must be able to withstand the shut-off head less the static head of the cargo pump but no less than 100 psi.

Cargo hose must be able to withstand at least 150 psi.

Cargo hose must be able to withstand the shut-off head plus the static head of the cargo pump.
