Esso Gettysburg HAER No. CA-354 Page 12 4. Cargo handling arrangements: The aft pump room, a tall compartment between the engine room and the no. 10 center cargo tank, contained the four main centrifugal cargo pumps, each rated at 6,000 gallons per minute (gpm) of sea water at 150 psig. They were driven by reduction-geared steam turbines located in the engine room. Two additional pumps in this room served for cargo stripping; they were rated 1,400 gpm at 150 psig. A final pump with its own piping system was installed to handle ballast water to and from no. 4 and no. 6 cargo tanks. Cargo-loading and discharge crossover connections, cargo-heating valves, and firesuppression piping were all provided on deck. In addition to two water-jet eductors included in the aft-pump-room piping to facilitate cargo tank cleaning, the ship was originally equipped with six Butterworth machines for cleaning the cargo tanks with heated seawater. The water main for the fire-suppression system, installed along the fore-and-aft walkway on deck, doubled as the main supply pipe for the Butterworth machines. 5. Steering gear: The ship’s electrically activated steering gear was of the 4-cylinder hydraulic opposed-ram type. PART III. SOURCES OF INFORMATION A.
