Esso Gettysburg HAER No. CA-354 Page 11 crew’s recreation room, dayrooms, chart room, radio room and hospital, are mechanically ventilated and air cooled in hot weather. 33 Heating in the crew spaces was provided through steam convector radiators. Radio shelves were provided in every cabin, and the three lounges each had a 21' television set. These were still enough of a shipboard novelty that the company writer felt it worth noting, “The sets are served by rotating, stainless steel antennas, especially designed and ruggedized for sea service.” 34 5. Safety: The Esso Gettysburg carried four metal lifeboats, each 24' x 8' x 3'-7", two on the Upper Bridge Deck and two on the Boat Deck aft. The port boat amidships and starboard boat aft were originally Diesel propelled with thirty-seven-person capacities. The remaining boats, equipped with oars, held forty persons. All the boats were suspended from gravity davits operated with electric winches. B. Mechanical Features: 1. Engine Plant: The ship was propelled by a single set of cross-compound turbines comprising a single-flow impulse high-pressure turbine and a single-flow impulsereaction low-pressure turbine. These were coupled to the drive shaft and single screw through a double reduction gear. Astern elements were built into the lowpressure turbine. Newport News Ship-building designed and built the engines; General Electric designed and built the reduction gear. Engine power: H.P. turbine 13,570 shp 5,950 rpm L.P. turbine 12,930 shp 3,436 rpm Propeller    26,500 shp 108.5 rpm 35 2. Boilers: The ship’s two two-drum watertube boilers, manufactured by Babcock & Wilcox, were located on a flat above the rear portion of the engine space. As originally constructed, each was fired by six Babcock & Wilcox “Iowa”-type steam/mechanical atomizing oil burners. The system was designed to supply steam to the high-pressure turbine chest at 815 pounds per square inch (psig) and 850 degrees F on a vacuum of 28.4 inches of mercury. 36 3. Electrical system: The ship’s electrical system comprised two 750-kW steampowered turbo generators. Emergency electrical gene-ration was provided by a 100-kW Diesel generator installed on the Boat Deck aft. --------------------------------------------------------------------------------------------------------------------------------------------------------------- 33 “Esso Gettysburg,” 3. 34 ibid. 35 “Esso Gettysburg,” 7. 36 Additional technical specifics about the propulsion and other mechanical systems (including a detailed pump ta-ble) appear in “Esso Gettysburg,” 9 - 13.
