The minimum bursting pressure for each cargo...

🔍 Key Concepts

• 46 CFR requirements for cargo hose assemblies used in transferring oil or hazardous materials • Relationship between working pressure and minimum bursting pressure (often expressed as a multiple, such as 4 times working pressure) • Differences between common cargo system pressures and safety margins required by regulation

💭 Think About

• Think about what safety margin the Coast Guard would reasonably require between normal operating pressure and the hose’s failure (bursting) pressure. • Consider what typical maximum allowable working pressure (MAWP) might be for cargo hoses and how many times higher the bursting pressure should be. • Compare each psi option with a realistic working pressure (for example, 100–150 psi) and decide which choice best reflects a conservative regulatory safety factor.

✅ Before You Answer

• Verify in 46 CFR (Tank Vessels / Oil & Hazardous Materials Transfer) what multiple of working pressure is required for hose bursting strength. • Check whether the regulation talks about minimum bursting pressure as a fixed psi number or as a multiple of the hose’s maximum working pressure. • Confirm that the value you pick provides an adequate safety factor above likely cargo transfer operating pressures (e.g., well above 150–200 psi).

The minimum bursting pressure for each cargo hose assembly must be at least __________.

300 psi

400 psi

500 psi
