Chip...if you have two differing images, it is not a mistake, so just leave it
........
It was just an assumption of mine that the vessel would have secondary diesel gen-sets for refrigeration and electricity. etc....so smaller seawater intercooler capacity for the secondary engines than for the larger main engine?
You can also be absolutely sure that each engine would have
independent seawater cooling......
The Our Lass III vessel spec indicates....[I read this as 2 x auxiliary, and 1 x main engine]
Auxiliary Engine 2 * MitsubishiMain Engine Mitsubishi 650hpJust for interest, does the real vessel have differing sizes of engine exhaust pipes?........is the larger diameter pipe exit from the Stdb side?
With such a large hull & capacity for ancillary functions, you could include engine intercooler seawater discharges .........some slow to medium speed peristaltic [hose pumps] would do the trick........absolutely continuous rating, low current draw reasonably inexpensive
