integration of the ship’s directives with those from higher  authority. Directives  can  be  useful  tools  for  the  engineer officer.  They  must  be  clear,  concise,  and  readily understood. The format and arrangement are prescribed in the  Department  of  the  Navy  Directives  Issuance System  Manual,  SECNAVINST    5215.1C.  The  engineer officer  and  other  officers  of  the  engineering  department are required to maintain directives binders according to the COs instruction. The binders should contain all directives (properly indexed and arranged) pertaining to the  officers’  jobs. SHIP’S BILLS The Standard Organization and Regulations of the U.S. Navy, OPNAVINST 3120.32B, contains the ship’s bills that guide the assignment of personnel to duties or stations  for  the  purpose  of  accomplishing  certain functions.   Each   ship’s   bill   is   classified   as   an administrative,  operational,  or  emergency  bill.  The watch, quarter, and station bill is an amplification of the Standard Organization and Regulations of the U.S. Navy. Administrative  bills  are  ship’s  bills  that  facilitate the assignment of personnel individually or by groups to stations or duties that pertain to routine operations or evolutions of the ship. Operational bills include the special sea detail bill, replenishment at sea bill, rescue and assistance bill, landing party bill, and visit and search, boarding, and prize crew bill. Emergency bills are ship’s bills that provide for the assignment of personnel individually or by groups to stations  or  duties  to  cope  with  emergencies.  Emergency bills include the general emergency bill, man overboard bill, and the CBR warfare defense bill. TYCOMs  furnish  ships  the  type  of  information necessary  to  permit  detailed  assignment  of  personnel. The  responsibility  for  and  maintenance  of  each  ship’s bill is assigned to a key officer, usually a head of a department.  Each  bill  must  give  division  officers enough guidance to permit assignment of personnel by name.  Each  bill  must  have  a  preface  containing  a statement  of  purpose,  assignment  of  responsibility  for maintenance of the bill, and information supplying background or guidance. It must have a tabulation showing assignments of individuals by billet or rate to stations  or  duties.  It  must  also  have  a  procedure containing all information and policies necessary to interpret the tabulated material. The procedures must include  special  responsibilities  of  individuals  with regard  to  planning,  organizing,  directing,  or  controlling the function or evolution to which the bill relates. The   engineer   officer   is   responsible   for   the maintenance of the rescue and assistance bill, general emergency  bill,  and  CBR  defense  bill.  The  rescue  and assistance  bill  provides  a  special  organization  equipped and  qualified  to  render  assistance  to  persons  or activities  outside  the  ship  or  to  perform  related functions. The general emergency bill provides the optimum  organization  needed  to  counteract  major emergencies and to abandon ship in an emergency. The CBR  warfare  defense  bill  provides  an  organization  and prescribes  the  procedures  to  minimize  the  effects  of  a biological or chemical attack. Each  division  officer  is  responsible  for  publishing and maintaining a watch, quarter, and station bill, which is a summary of his assignments of personnel to station and duties according to the battle bill and each of the ship’s  bills.  The  watch,  quarter,  and  station  bill  is arranged in standard tabular form. It has columns to enter  each  individual’s  name  and  rate,  data  from  the battle  bill,  and  duties  assigned  under  each  of  the  ship’s bills. The watch, quarter, and station bill should be prominently posted in a space that is frequented by all personnel of the division. 1-23
