🔍 Key Concepts

• 33 CFR requirements for oil transfer hoses on vessels and facilities • The difference between working pressure and bursting pressure in hose design • Construction and marking requirements such as metallic reinforcement and identification markings

💭 Think About

• Look up the specific CFR section that covers design and construction standards for oil transfer hoses and list each requirement it mentions. • Ask yourself: does the regulation require the hose to safely operate at a certain pressure, or to survive far above that pressure without bursting? • Consider whether every oil transfer hose is required to have metallic reinforcement, or if the regulation focuses more on pressure capacity and proper identification.

✅ Before You Answer

• Verify the exact language about working pressure versus the sum of the relief valve setting and static head. • Confirm whether metallic reinforcement is explicitly stated as a requirement in the regulation, or just common practice. • Check that identification markings (such as maximum working pressure and manufacturer) are indeed required on the hose.
