Question 331 Deck General

The correct answer is B) Commandant (G-MTH). According to 46 CFR 154.12, the carriage of a liquefied gas not appearing in Table 4 of 46 CFR Part 154 must be approved by the Commandant (G-MTH). This is because the Commandant has the authority to approve the carriage of liquefied gases that are not specifically listed in the regulations. The other options are incorrect because the Officer in Charge, Marine Inspection (A) does not have the authority to approve the carriage of unlisted liquefied gases, the vessel owner (C) cannot approve this independently, and the American Bureau of Shipping (D) is a classification society, not the regulatory authority for this matter.
