Q

What pressure shall cargo hoses carried on tank vessels be able to withstand?

🔍 Key Concepts

• 46 CFR requirements for tank vessels and cargo gear • Specific section on cargo hose construction and test pressure • Difference between maximum working pressure and required test pressure

💭 Think About

• Is the regulation asking about the hose’s normal operating pressure, or the minimum pressure it must safely withstand during testing? • For petroleum/chemical cargoes, would the Coast Guard set this minimum closer to typical system pressures or well above them as a safety margin? • Compare the listed pressures: which looks most like a regulatory minimum designed to cover a wide range of cargo systems?

✅ Before You Answer

• Look up the exact wording in 46 CFR, subchapter dealing with tank vessels (e.g., Part 39, 154, or 56 as applicable). • Confirm whether the rule says "shall be able to withstand" a specific psig test pressure for cargo hoses. • Verify that the chosen value matches the explicit numeric minimum in the regulation, not just what seems reasonable.
