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 pressure of __________.

Correct Answer: Option B — 105 psi

Per 33 CFR 156.170, oil transfer hoses must be tested to 1.5 times the maximum allowable working pressure. If the maximum pressure is 70 psi, the required static test pressure is 105 psi. This safety margin ensures the hose can withstand pressure surges during transfer operations without catastrophic failure or leakage.
