Question 1 of 2066636ee728f7522a1c517e0e

You are inspecting the nonmetallic oil transfer hoses on the vessel you operate. The maximum allowable pressure of the hose is 70 psi. Your inspection confirms the hose did not burst, bulge, leak or abnormally distort under the required static liquid. Which pressure was used for this test?

🔍 Key Concepts

• 46 CFR requirements for testing nonmetallic oil transfer hoses • Relationship between maximum allowable working pressure (MAWP) and test pressure • The typical safety factor used when pressure-testing hoses and piping

💭 Think About

• If a hose is rated for a certain maximum working pressure, should the test pressure usually be lower than, equal to, or higher than that rating? Why? • Think about why the regulations require a pressure test: is it just to match normal conditions, or to prove the hose can safely handle more than its normal load? • Compare each answer choice to the 70 psi rating: which ones represent a realistic regulatory test factor rather than something extremely low or unrealistically high?

✅ Before You Answer

• Look up the specific 46 CFR section on oil transfer hose testing and note the required multiplying factor for test pressure versus MAWP • Confirm whether the test is described as a static liquid pressure test and what percentage or multiple of the hose’s maximum allowable working pressure is mandated • Make sure the option you choose is an exact match to the numerical requirement in the regulation (not just “close” to it)
