self-sufficient. That’s   why   close   scrutiny   of   their operating   and   treatment   records   is   so   important.   The importance   of   maintaining   accurate   WHB   operating records,   boiler   water   and   feedwater   chemistry   logs   and records   must   not   be   underestimated.   The   engineer officer   and   assistants   use   the   data   in   these   records   to measure   the   performance,   stability,   efficiency,   and   state of   material   readiness   of   the   engineering   plant. Remember,   the   decision-making   process   involved   in effective   WHB   operations   and   the   water   chemistry program   aboard   your   ship   is   supported   by   the information   contained   in   these   records.   To   be   an effective   engineer   and   supervisor,   you   should   be familiar   with   the   purpose,   content,   and   general procedures   to   properly   review   and   train   your   personnel to  maintain  each  of  these  records. UPDATE   WHB   OPERATING   RECORDS WHB   operating   records   information   is   derived   and compiled   from   several   different   logs   and   inspection reports. Basic   boiler   information   is   recorded   in   the engineering   log   as   events   occur.   These   events   normally include    start-ups,    shutdowns,    and    blowdowns. However,   the   primary   log   where   the   majority   of information   is   compiled   is   the   WHB   Boiler   Water Chemistry   Worksheet/Log.   This   log   is   updated   as events   occur   and   is   closed   out   on   a   daily   basis. Basically,   all   maintenance   performed   on   the   boiler   and its   operating   systems,   chemical   treatments,   and operating   hours   are   entered   in   either   the   Remarks section  or  the  Boiler  Data  section  on  the  backside  of  the WHB   Boiler   Water   Chemistry   Worksheet/Log. The  last  source  of  boiler  status  information  that  we will   discuss   is   the   Boiler   Inspection   and   Repair Management   Information   System   (BIRMIS)   report. This   system’s   purpose   is   to   enhance   the   value   of auxiliary   boiler   inspections.   The   BIRMIS   report contains   useful   information   concerning   the   health   of your   WHB.   This   report   is   filled   out   by   the   boiler inspector  at  the  completion  of  any  standard  or  emergent boiler   inspection.   As   a   supervisor   you   must   understand the   information   provided   in   this   report   so   you   can effectively   plan   (schedule)   and   correct   the   listed discrepancies.   In   figure   1-10   of   this   next   section,   there is   a   sample   of   a   BIRMIS   report.   This   sample   report should  help  you  identify  and  understand  the  information provided. As  you  can  see,  the  BIRMIS  report  is  broken  down into   three   distinct   sections. This   sample   report   is representative  of  the  inspection  of  the  No.  3  WHB.  The first   section   is   the   cover   sheet   and   some   standard information   that   you   provide   to   the   inspector.   The second   section   is   for   inspector   comments.   In   this sample,   the   inspector   chose   to   provide   a   list   of references   that   would   be   used   as   guidelines   to   perform the   inspection.   The   third   section   contains   (from   left   to right)   the   item   (component)   inspected,   the   number   of d i s c r e p a n c i e s     n o t e d     ( e n t r y     c o n d i t i o n ) ,     t h e recommended   repair,   and   the   deficiency   status   code. For   clarification   and   standardization,   the   BIRMIS system  uses  set  codes  to  identify  each  boiler  component and   subcomponents   being   inspected.   As   in   the   sample form,  the  C  represents  the  boiler  tubes  (primary),  and the  Cl  and  Cll  represent   specific   sections   of   the   tubes. And  finally,  the  entry  condition  is  the  sequential  listing of   each   discrepancy   found   for   that   component. UPDATE  WHB  WATER  TREATMENT RECORDS As  a  GS  supervisor  you  must  become  more  familiar with   updating   and   reviewing   WHB   water   treatment records.   Depending   on   your   assignment   within   the engineering  department  and  if  your  ship  has  boilers,  you will   be   tasked   either   daily   or   intermittently   with updating   and   reviewing   these   records.   In   the   remainder of  this  section  you  will  find  two  basic  check  sheets  (figs. 1-11  and  1-12)  that  you  can  use  to  properly  review  the WHB   water   treatment   records.   These   check   sheets   are not  mandatory,  but  the  information  is  very  helpful.  This information   was   taken   directly   from   an   NSTM  and   the numbers  listed  at  the  end  of  each  question  should  be  a help  to  you. SUMMARY In  this  chapter  we  have  discussed  various  programs, reports,   and   records   needed   by   GS   supervisors.   The titles  of  the  different  sections  of  this  chapter  may  sound like   many   of   those   presented   in   some   engineering administration   publications.   Even   though   the   topics   are in   other   publications,   the   information   in   this   chapter   is specific   togas   turbine-powered   ships.   Throughout   this chapter  you  have  been  referred  to  the  EOSS,  applicable technical  manuals,  or  the  PMS  for  specific  information. You  must  use  these  references  to  guide  you  through  the procedures.  Use  of  the  EOSS,  technical  manuals,  and the  PMS  will  help  you  make  the  proper  decisions  to  best handle  the  duties  of  a  GS  supervisor. 1-25
