Question 116Safety & Environmental - 1st Asst/Chief70% to pass
A tank vessel with an oil cargo capacity of 5000 barrels is required by regulations to have a fixed container, or enclosed deck area under or around each oil loading manifold and each oil transfer connection point. The capacity of these containment areas is based upon _______________.
AI Explanation
The correct answer is A) inside transfer hose diameter or loading arm nominal pipe size diameter.
The capacity of the containment areas around oil loading manifolds and transfer connection points is based on the size of the transfer hoses or loading arms, not the other factors listed. This is in accordance with U.S. Coast Guard regulations, which require the containment capacity to be at least equal to the maximum volume of oil that could be discharged from the largest pipe connected to the manifold or transfer connection.
The other options are incorrect because the number of tank vents, overflows, and fill pipe connections, as well as the cargo oil service pressure, do not directly determine the required containment capacity, which is based on the size of the transfer equipment.
