e.  Check  the  lubrication;  flush  the  governor sump and refill it with proper oil. f. Check the setting of the needle valve. g.   Make repairs. When you have completed the repairs, start the engine and check its operation. When it is operating properly, notify the engineer officer and the bridge. 2.  Engine  cooling  water  temperature  above  the allowed  limit a. b. c. tank d. e. valves. f. g. Notify the bridge. Reduce the load and the speed of the engine. Check the freshwater level in the expansion Check the saltwater discharge pressure. Check  the  sea  suction  and  the  discharge Vent the freshwater and the saltwater pumps. Check  the  setting  and  operation  of  the temperature regulating valve, 3. Failed main engine lube oil pressure a. Secure the engine immediately. b.   Notify the engineer officer and the bridge. c.  Check  the  sump  oil  level,  the  piping,  the filters,  the  strainers,  and  the  lube  oil  pump  capacity. Make the repairs. d.   After you have completed the repairs, notify the engineer officer and the bridge. For  more  generalized  examples  of  main  engine (diesel-drive)  casualties,  refer  to  “Damage  Control  - Engineering Casualty Control,” Chapter 079, Volume 3, of NSTM. To  obtain  detailed  information  on  diesel  engine casualty control procedures, refer to the manufacturer’s instructions,   the   pertinent   type   commander’s instructions,   and   the   ship’s  Engineering   Casualty Control  Manual. WATCH  STANDING You will spend much of your time aboard ship as a watch   stander.   How   you   stand   your   watch   is   very important to the reliability of the engineering plant and the entire ship. To be a successful watch stander, you must  do  the  following; l   Have   the   skills   to   detect   unusua1   noises, vibrations, or odors that may indicate faulty machinery operation. l   Take   appropriate   and   prompt   corrective measures. l  Be  ready,  in  emergencies,  to  act  quickly  and independently. l  Know  the  ship’s  piping  systems  and  HOW, WHERE, and WHY they are controlled. l  Know  each  piece  of  machinery:  how  it  is constucted,   how   it   operates,   how   it   fits   into   the engineering   plant,   and   where   related   equipment   is controlled. l   Be   able   to   read   and   interpret   measuring instruments. l   Understand   how   and   why   protective   devices function   (relief   valves,   speed   limiting   governors, overspeed trips, and cut-in and cutout devices). l  Recognize  and  remove  fire  hazards,  stow  gear that is adrift, and keep deck plates clean and dry. l   NEVER try to operate a piece of equipment that is defective. l   Report all unsafe conditions to the space or plant supervisor. l Know the status of every piece of machinery at your  station. l Promptly handle any necessary change in speed or  setup,  and  record  correctly  all  data  concerning  the operation and maintenance of the machinery. l   Be sure the log is up-to-date and the status boards are  current. l   Know what machinery is operating and what the night orders and standing orders are before you relieve the  watch. Above all, if you don’t know-ASK!   A noise, odor, or condition may seem abnormal to you, but you may not  be  certain  whether  it  is  a  problem.  When  that happens, call your immediate watch supervisor. You can best gain the respect and confidence of your supervisors and shipmates if you stand a good watch. Relieve the watch on time or even a little early if possible to be sure you know the condition of the machinery and what you need to do.
