Your vessel is carrying 84,000 barrels of oil for discharge. The cargo hoses have an inside diameter of 14 inches. When four hoses are connected to the manifold, the container around the manifold must hold a total of how many barrels?

Correct Answer: Option B — Four

Under 33 CFR 155.320, cargo hoses with an inside diameter of 12 inches or more require a manifold containment capacity of at least 2 barrels per side or connection group. Two connected hoses meeting this size threshold dictate a total 4-barrel capacity requirement.
