🔍 Key Concepts

• Liquefied gas cargo hose requirements under 46 CFR (Cargo and Bulk Dangerous Cargoes) – verify current section for gas carriers • Difference between working pressure and bursting pressure for cargo hoses • Safety margin typically required between normal operating (working) pressure and the hose’s burst pressure rating

💭 Think About

• First, think about why regulators require a margin between working pressure and bursting pressure. How large would that margin need to be to remain safe under abnormal surges? • Compare each option: which ones are tied to working pressure of the hose itself and which are tied to something else like the cargo pump? Which is more reliable as a design basis? • Ask yourself: for a hazardous cargo like liquefied gas, would the factor of safety be relatively small (like 1.5) or significantly larger? How does that help you narrow the options?

✅ Before You Answer

• Check in 46 CFR gas carrier requirements what multiplying factor is specified between maximum working pressure and bursting pressure for cargo hoses used with liquefied gases • Verify that the requirement is based on the maximum working pressure on the hose during cargo transfer, not just a “minimum” or the pump discharge pressure • Eliminate any options that do not clearly reference both: (1) working pressure of the hose during transfer, and (2) the correct regulatory safety factor
