A vessel loads edible oil in a deep tank through a manhole at the mid-length of the tank. In order to fill the tank to maximum capacity, what trim should the vessel have?

Correct Answer: Option A — In level trim

Loading a deep tank via a central manhole requires a level vessel trim to ensure the liquid spreads evenly fore and aft within the boundary bulkheads, preventing premature air pockets and allowing accurate maximum capacity utilization.
