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 D — In level trim

To fill a deep tank to maximum capacity through a centrally located manhole, the vessel must be in level trim. Any significant bow or stern trim would trap air pockets at the elevated end of the tank, preventing it from being completely filled.
