Question 1058 Deck General

The correct answer is C) officer-in-charge of the vessel which is loading. According to U.S. regulations, no vessel can come or remain alongside a tank vessel while it is loading A, B, or C grade cargo without permission from the officer-in-charge of the vessel which is loading. This is because the officer-in-charge is responsible for the safe loading operations and must ensure that the proximity of other vessels does not pose a safety risk. The other options are incorrect because the tank ship owner, terminal manager, and USCG captain of the port do not have direct control over the loading operations and are not responsible for granting permission in this specific scenario.
