center will file the green copy until an answer to the feedback report is received. SHIP’S  MAINTENANCE  ACTION  FORM The  Ship’s  Maintenance  Action  Form,  OPNAV 4790/2K, is used by maintenance personnel to report deferred  maintenance  and  completed  maintenance.  This form also allows the entry of screening and planning information  for  management  and  control  of intermediate maintenance activity (IMA) workloads. The  OPNAV  4790/2K  is  originated  in  the  work center. It is screened for accuracy and legibility, and initialed by the division officer and engineer officer before  being  forwarded  to  the  3-M  coordinator.  When the  form  is  used  to  defer  maintenance,  the  3-M coordinator  will  send  two  copies  back  to  the  originating work  center  to  hold  on  file.  When  the  deferred maintenance is completed, one of the copies is used to document the completion of the maintenance. CURRENT  SHIP’S  MAINTENANCE PROJECT The  standard  Current  Ship’s  Maintenance  Project (CSMP) is a computer-produced report listing deferred maintenance and alterations that have been identified through Maintenance Data Collection System (MDCS) reporting.  Copies  of  the  CSMP  should  be  received monthly.  The  engineer  officer  is  provided  with  a  copy for  each  of  the  engineering  department  work  centers, and each work center is provided a copy that shows only its  own  deferred  maintenance. The  purpose  of  the  CSMP  is  to  give  shipboard maintenance  managers  a  consolidated  list  of  deferred corrective maintenance. They can use the list to manage and control maintenance in the deferred items. The work  center  supervisor  is  responsible  for  ensuring  the CSMP accurately describes the material condition of his work center. Each  month  when  a  new  CSMP  is  received, verified,  and  updated,  the  old  CSMP  may  be  destroyed. OPNAVINST 4790.4B, contains the instructions and  procedures  needed  to  complete  and  route  all  3-M Systems  forms. ADDITIONAL  RECORDS The engineering department records and reports discussed  in  this  section  inform  responsible  personnel of  coming  events  (including  impending  casualties). They  supply  data  for  the  analysis  of  equipment performance, provide a basis for design comparison and improvement,   or   provide   information   for   the improvement  of  maintenance  techniques  and  the development of new work methods. The records are those papers that must be compiled and retained on board (in original or duplicate form) for prescribed periods.  They  are  primarily  used  for  reference  in administrative and operational matters. The reports are of either a one-time or recurring nature. Recurring reports are required at prescribed or set intervals, while one-time reports need to be made on the occurrence of a given situation. ENGINEER OFFICER’S NIGHT ORDER BOOK The engineer officer keeps a Night Order Book as part of the engineering records. In it he enters orders with respect to (1) operation of the engineering plant, (2) any special orders or precautions concerning the speed and operation of the main engines, and (3) all other orders for the night for the EOOW. The Night Order  Book  is  prepared  and  maintained  according  to instructions issued by the type commander. Some type commanders require that the Night Order Book have a specific  format  that  is  standard  for  ships  of  the  type. Others allow use of a locally prepared form but specify certain  contents  of  the  book. The   Night   Order   Book   must   contain   orders covering  routine  recurring  situations  (engineering department  standing  orders)  as  well  as  orders  for  the night for the EOOW. Standing orders are issued by the engineer officer as a letter-type directive (instruction), according to the ship’s directives systems. A copy of the instruction is posted in the front of the Night Order Book. Orders for the night for the EOOW generally specify the boilers and other major items of machinery to be used during the night watches. A form similar to the one illustrated in figure 2-14 is in use in some ships for the issuance of the engineer officer’s night orders. The Night Order Book is maintained in port and at sea. In the temporary absence of the engineer officer in port, the engineering department duty officer maintains it. Underway, the Night Order Book is delivered to the EOOW before 2000 and is returned to the log room before 0800 of the following day. In addition to the EOOW,  principal  engineering  watch  supervisors  and the oil king should read and initial the night orders for the watch. In port, the leading duty petty officer of each engineering   division   and   the   principal   watch supervisors should read and initial the night orders. 2-24
