No sir, the APU is a SEPERATE entity. Now realize, I am talking about APL ships. I am not familiar with this specific ship, but historically, the EMERGENCY generators have always used a separate fuel source because they can control that far easier than the fuel they get in a foreign port.The generators are the auxiliaries. Do you have anything that says there is an additional one beyond the 4 main generators and the emergency generator?
I see one main engine, 4 generators (2 for ship's power, 2 for the cargo), plus one emergency generator on deck level.
