l l l l l l Keep  the  shaft  packing  glands  adjusted properly.  A  small  amount  of  leakage  is necessary  to  prevent  burning  out  the packing,   but   excessive   leakage   wastes boiler  feedwater. Check  and  maintain  the  proper  lube  oil level  in  the  main  feed  pump  sump  tank. Keep the valve packing glands tightened to  prevent  leakage. Keep the watch station clean; remove fire hazards  by  wiping  up  oil  and  picking  up rags and other stray gear. Keep alert for unusual sounds, vibrations, temperatures, and pressures from operating equipment. Keep the standby pump ready for instant use. Lube Oil Pump The  following  are  duties  you  will  perform while assisting the pumpman at the lube oil pump station: l l l l l l Maintain   the   proper   lube   oil   pump discharge pressure and the proper lube oil temperature. Keep   the   standby   pump   on   automatic standby. Shift  and  clean  the  main  lube  oil  strainers at  least  once  each  watch. Check  the  lube  oil  system  for  leaks,  and maintain the proper oil level in the main engine sump tank. Operate the lube oil purifier as directed. Regulate  the  cooling  water  flow  through the lube oil cooler to maintain the correct oil outlet temperature. Main Condensate Pump The  following  are  duties  you  will  perform while   assisting   the   pumpman   at   the   main condensate  pump  station: . Keep the condensate in the condenser hot well  at  the  proper  level. Frequently  check  the  exhaust  trunk  and main  condenser  overboard  for  abnormal temperatures. Check  the  main  condensate  pump  bearings for proper oil pressure and temperature. Start  or  secure  an  additional  pump,  as required, to keep the condensate level at the  correct  height. Constantly  check  for  unusual  conditions (vibrations,   sounds,   and   high   or   low temperatures  or  pressures)  of  operating equipment. All watch standers should be constantly alert for signs of leakage in all parts of the steam and water  systems.  The  following  are  some  of  the more  common  causes  of  feedwater  waste: .  Leaks  in  pipe  fittings,  flanges,  valve  and pump packing glands, pump housings, and relief   valves l  Excessive  gland  sealing  steam Remember,  a  poorly  operated  plant  reflects on  the  ability  of  the  watch  stander. SHAFT  ALLEY  WATCH Another main engine duty is that of keeping watch  on  the  bearings  of  the  propeller  shafts leading   from   the   reduction   gears   (or   motors of  a  turboelectric-driven  ship)  to  the  ship’s propellers.  As  a  shaft  alley  watch  stander,  you may  perform  the  following  duties: Check   all   spring   bearings   for   proper lubrication. This includes correct oil level, condition  of  the  oil,  proper  operation  of self-oiling   devices   (ring   or   chain),   and bearing temperature. Check and adjust the stern tube gland for the  correct  amount  of  leak-off. Pump the shaft alley bilge, as authorized by  the  EOOW  and  OOD. During  high  speed,  keep  alert  and  observe any  abnormal  rise  in  bearing  temperature. Report  hourly,  by  phone,  to  the  control engine room under normal conditions and if  abnormal  conditions  develop. Operate the main thrust bearing when it is located in the shaft alley. 1-22
