So even if it had 150,000 humans on board, the humans might consume less liquids than the engine... Those humans would also only use 1/6th as much energy (when assuming around 9.2m Calorie per liter of diesel). So the energy used by that engine could also "run" a million humans. Whatever that ship is carrying, it might be more energy efficient to let people carry it... Burning through four liters of diesel a second/a bathtub a minute is insane. I'm a bit tired, but I hope I got that math about right.
