The minimum bursting pressure for each cargo...

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

🔍 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).
