During the annual inspection by the owner, each nonmetallic oil transfer hose must not burst, bulge, leak, or abnormally distort under static liquid pressure of at least __________.

Correct Answer: Option C — 1½ times the maximum allowable working pressure

33 CFR 154.500 mandates that nonmetallic oil transfer hoses must be tested annually. The hose must withstand a static liquid pressure of 1.5 times the maximum allowable working pressure (MAWP) without bursting, bulging, leaking, or showing abnormal distortion, ensuring the integrity of the transfer system under operational stress.
