"SALT WATER CONVERTER" is located on the port side in the same position as Auxiliary Condenser "A".
NOTE 1: Fuel oil is carried in the inner bottom tanks (just above the keel) and SETTLING TANKS are located port and starboardof the machinery space (settling tanks are used to allow impurities in the fuel, such as water, to settle out before the fuel is used).
Oil (either cargo or fuel) can also be carried in deep tank number three, which was located just aft of the machinery space.Viewer Comments:
