Which statement is TRUE concerning cargo hose on tank barges?

A Cargo hose must be able to withstand the shut-off head less the static head of the cargo pump but no less than 100 psi.

B Cargo hose must be able to withstand the static head of the cargo pump but no less than 100 psi.

C Cargo hose must be able to withstand at least 150 psi.

D Cargo hose must be able to withstand the shut-off head plus the static head of the cargo pump.

AI Explanation

The correct answer is C) Cargo hose must be able to withstand at least 150 psi. The regulations for tank barges specify that cargo hoses must be able to withstand a minimum pressure of 150 psi. This requirement ensures the hoses can safely handle the high pressures that may be encountered during cargo transfer operations. The other options are incorrect because they do not accurately reflect the regulatory requirement. Option A is too low, option B does not account for the shut-off head, and option D includes both the shut-off head and static head, which is not the specified minimum pressure.
