is used by the work center supervisor for schedul- ing  weekly  maintenance.  When  a  maintenance action is completed, it is crossed out. A circle is drawn   around   incomplete   maintenance.   The reason  for  any  maintenance  requirement  that  was not completed during the quarter is given on the back  of  the  schedule.  The  completed  quarterly schedule  is  retained  for  1  year  as  a  planned maintenance  record. Weekly Schedule The   weekly   schedule   shows   all   planned maintenance scheduled for completion in a work center during a given week. The weekly schedule is  posted  in  the  work  center  and  is  used  by  the supervisor  to  assign  personnel  to  perform  the required  maintenance.  The  weekly  schedule  is  also used by the division officer as a basis for updating the quarterly schedules. The  weekly  schedule  provides  the  following information: 1.  The  work  center  and  the  appropriate  dates. 2.  A  list  of  components  in  the  work  center. 3. The names of personnel that are assigned to  perform  specific  maintenance  requirements. 4.  MIP  numbers. 5. Columns for listing PMS maintenance re- quirements  to  be  performed  during  the  week. 6. Outstanding repairs, PM checks, and situa- tion  requirements  due  in  the  next  4  weeks. (Outstanding repairs are corrective maintenance actions that have not yet been done because they are beyond the capacity of the ship’s work force, or  because  there  is  a  lack  of  spare  parts  or proper  tools  for  the  job.) The   work   center   supervisor   checks   the quarterly  schedule  and  draws  up  a  list  of  all planned  maintenance  system  (PMS)  requirements for the coming week. The supervisor then checks the   maintenance   index   pages   (MIPs)   for   any related maintenance requirements and for daily and  weekly  PMS  checks.  (Weekly  requirements should generally be entered on Monday for easier rescheduling.)  The  work  center  supervisor  also fills  in  the  Outstanding  Repairs  Due  column  as necessary. After assigning personnel by name to specific  maintenance  tasks,  the  supervisor  then posts  the  weekly  schedule  in  the  work  center. Maintenance  personnel  check  the  weekly schedule by their assignments. After they obtain all  the  maintenance  requirement  cards  (MRCs), tools,  and  materials  they  will  need,  they  start performing the assigned maintenance work. They report all the completed tasks to the work center supervisor. If the assigned maintenance was not completed,  they  report  the  reason  why.  The  super- visor  then  crosses  out  all  the  completed  actions and  circles  those  that  were  not  completed.  The supervisor  reschedules  the  uncompleted  main- tenance  tasks  as  conditions  permit. In  addition  to  the  maintenance  provided  by the cycle, quarterly, and weekly PMS schedules, your  ship  may  undergo  special  types  of  main- tenance during the times when the ship is not in full  operation.  For  example,  when  your  ship  is in a yard for overhaul, the general maintenance requirements  are  usually  reduced.  The  regular PMS schedules and documents are then supple- mented by planned maintenance during overhaul (PMDO),   MIPs,   and   MRCs   for   any   inactive systems  and  equipment  on  board.  PMDO  features include 1.   maintenance   requirements   necessary   to avoid  deterioration  of  inactive  systems, 2. start-up maintenance actions near the end of  the  overhaul  period,  and 3.   operational   testing   to   ensure   system readiness. RECOMMENDATIONS   FOR OVERHAUL  OR  REPAIR When  you  know  there  is  an  upcoming  yard period  or  tender  availability  (TAV)  period,  you should  meet  with  your  division  officer  and  prepare a list of equipment that might need repair or any spaces that may need lagging or changes. Enter this  information  on  an  OPNAV  4790/2K,  Ship’s Maintenance  Action  Form,  commonly  known  as a   “2-Kilo.”   After  the  2-Kilo  is  approved,  you should  forward  it  to  the  3-M  coordinator  to  be included  with  other  ships’  requests. As   a   senior   Ship’s   Serviceman,   you   must always  scrutinize  your  equipment  and  spaces for  any  necessary  maintenance.  You  must  be knowledgeable  of  your  PMS  schedules  and  of the   policies   of   your   ship   in   regard   to   main- tenance  reports  and  inspections.  For  additional information   on   the   3-M   Systems,   you   should refer  to   Ship’s   Serviceman   3   &   2,   Military Requirements   for   Petty   Officer   Third   Class, Military  Requirements  for  Petty  Officer  Second Class,   Military   Requirements   for   Petty   Officer First  Class,  Military  Requirements  for  Chief Petty  Officer,  and  the  Ships’    Maintenance and   Material   Management   (3-M)   Manual, 3-24
