Question 2271Deck General70% to pass
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 _______________.
AI Explanation
The correct answer is B) 105 psi.
The reasoning is based on the U.S. Coast Guard regulations for inspecting nonmetallic oil transfer hoses. The maximum allowable pressure of the hose is 70 psi, as stated in the question. However, the hose must be tested to 1.5 times the maximum allowable pressure, which is 105 psi (70 psi x 1.5 = 105 psi). If the hose did not burst, bulge, leak, or abnormally distort under the 105 psi static liquid pressure test, it passes the inspection.
The other options are incorrect because:
A) 70 psi is the maximum allowable pressure, not the required test pressure.
C) 140 psi and D) 210 psi are too high and would exceed the 1.5 times the maximum allowable pressure requirement.
