Question 1148 Deck General

The correct answer is B) Commandant, U.S. Coast Guard. The reason is that the Commandant of the U.S. Coast Guard has the authority to approve cargo piping arrangements for barges, including allowing cargo piping to pass through machinery spaces if the barge is designed to carry only grade E products. This is in accordance with the applicable regulations and requirements overseen by the Coast Guard for the design and operation of such vessels. The other options are incorrect because the American Bureau of Shipping, the vessel owner, and the National Cargo Bureau do not have the regulatory authority to approve this type of cargo piping arrangement. Their roles are more limited in scope compared to the oversight and approval authority of the U.S. Coast Guard Commandant in this specific case.
