This loss was made up by the operation of two distiller condensers supplying a total of 80.000 gallons per day. The entire ship's fresh water supply came from this source. In addition to the main propulsion plant and the distiller condensers, 5-M Division was responsible for the auxiliary turbo- generators and the various auxiliary machinery located on the lower machinery level, such as, feed pumps, circulating pumps, lube oil pumps, bilge pumps, fresh water pumps, and fire and sanitary pumps. the main control panel, an oiler watchn on the lower machinery level, and an evaporator watchn on the Distiller condensers. These men on watch kept constant check on the gages and meters that indicated whether or not the plant was functioning properly. Cause of any abnormal operation must be determined immediately and the fault corrected so as to keep the plant opera- ting. Many times this called for work throughout the night since a mechanical apparatus is not respectful of an 8 hour work day. It is due to the willingness of the men in 5-M Division to thus subordinate themselves to the needs of the machinery that the main plant functioned at its rated horsepower day and night, month after month, through smooth or rough weather.

- DIVISION The maintenance of the ship's main propulsion plant was the responsibility of 5-M Division. A twin screw, turbo-electric drive, propulsion plant furnished the 20,000 H.P. necessary to push the ship along at 25.5 knots. The source of all power aboard the ship was four, 600 p.s.i., 8400 F. boilers installed in pairs, two in each of the machinery spaces. The superheated steam drove the 6890 K.W'. main turbo-generators at 3600 R.P.M. producing a 60 cycle, 3 phase current, 3400 volts. The electrical power, thus gener- ated, operated the two main motors. These motors were 60 pole, Y connected, synchronous motors. Each turbo-generator normally supplied only one motor. Since the starting torque of a synchronous motor is exceeding- ly small, the two main motors were made, so that during the starting period, they acted as induction motors and consequently l Opening throttle valve on main turbine Checlqing jacking gear on main motor produced a large starting torque. When the motor 1S up to speed, 3 it then acts as a synchronous motor. A pressure-closed feed system was used on the ADMIRAL CAPPS. To complete the cycle of this system the steam leaving the main turbine was condensed in the main condenser and then pumped to the low pressure feed heater by the main condensate pumps. Here the condensate was heated and then discharged to the deaerating tank. In the deaerating tank the condensate was further heated and the oxygen was removed from the water. From the deaerating tank the condensate, now termed feed water, was pumped back into the boilers by the main feed pump, thus completing the steam cycle. ,- IQ cows f+ - A 0,4 l ..f I 1 1 L4 XVHYS SOE? iiflff Elppiifafli. d by the 80.000 from this so' ' f ' In ad condenser generators 4 '41 A+.f3-- Ll - 53:11 ' 3 . . .4 . .. xi lower machine lube oil p 11,-viva. im' s ..4-. , , sanitary of r,

H DlvlsloN To many of the crew, Sick Bay represented that normally avoided section of the main deck where one was forced to re- spond to the orderg Lay down to the Sick Bay for revaccinationn. Yet here was a small modern hospital, superbly equipped and ably manned throughout the life of the Admiral W. L. Capps. By far the most important function of H Division was the physical fitness of the ship's personnel. To keep as many men in good health and on the job for the longest possible time was the prime concern of the Medical Department. ' Morning and afternoon sick calls were provided for the outapatients. These patients were seen in the treatment room, complaints were elicited and therapy was provided. A complete X-Ray unit assisted in diagnostic procedures. A quiet room facili- Paticnts resting in the wards . L5- A12 operation in progress tated the eye, ear, nose and throat treatments as well as physio- therapy. Nearby was a Well stocked Pharmacy where every type of commonly used drug was dispensed. For the in-patient or bed case, there were 5 modern hospital wards With a total capacity of 66 beds. Included were 3 large wards, a sick officers quarters, and an isolation ward for infectious diseases. Hospital corpsmen were in constant attendance and ward rounds by the Medical Olhcers were made on each patient twice daily. Every kind of common hospital ailment was seen in the wards throughout the voyages of the AP-121.
