According to U.S. regulations what is the maximum allowable working pressure (MAWP) for each hose assembly used for transferring oil?

Correct Answer: Option A — more than the sum of the pressure of the relief valve setting

Title 46 CFR 156.170 and 33 CFR 154.500 mandate that oil transfer hoses maintain a maximum allowable working pressure exceeding the relief valve setting or maximum pump pressure to prevent catastrophic hose rupture.
