Cold  Plant During   a   ship’s   scheduled   PMA/SRA/ROH,   Naval Warfare   Center   Ships   System   Engineering   Station (NAVWARCENSSES)   Philadelphia   will   schedule   an EOSS  verification  check  (cold  plant)  approximately  4 weeks   prior   to   the   end   of   the   ship’s   availability.   This will   ensure   that   all   system   modifications/installations affecting  EOSS  are  completed  before  the  check  in  order to  permit  an  accurate  update. At  the  end  of  the  verification  check  a  copy  of  the affected   EOSS   documentation   must   be   annotated   and given  to  the  ship  for  review  and  use  when  approved  by the   commanding   officer.   The   annotated   documents   will be  used  until  the  final  laminated  EOSS  is  received (usually   within   12   weeks). Hot  Plant The  hot  plant  checks  are  conducted  just  as  the  name describes.  This  means  the  plant  is  fully  operational,  and the   checks   are   normally   performed   as   a   training evolution   in   the   form   of   casualty   control   drills.   These checks  are  usually  used  to  fine  tune  watch-stander efficiency   and   identify   procedural   deficiencies. USING   THE   FEEDBACK   SYSTEM Since  the  EOCC  procedures  makeup  only  part  of the  overall  EOSS,  we  will  discuss  the  use  of  the  EOSS feedback   system. The  EOSS  feedback  system  is  the means  by  which  you  may  make  changes  in  your  EOSS. Any  naval  activity  may  originate  these  requests.  The information   in   this   section   will   cover   the   proper preparation  of  feedback  reports  and  other  aspects  of  the feedback   system. You   must   submit   feedbacks   to   accomplish   the following: 1.   Obtain   replacement   documents,   holders,   covers, and   twisties. 2.   Recommend   approval   of   revisions   for: a.   Procedural   changes   to   correct   document errors. b.   Configuration   changes   for   authorized equipment   or   piping   installations. Feedback   reports   should   NOT   be   submitted   just because   the   EOSS   conflicts   with   other   technical guidance.   The   EOSS   always   supersedes   other guidance!  An  EOSS  feedback  should  be  submitted  only when   the   EOSS   is   suspected   to   be   in   error.   Feedback on   other   documentation   such   as   technical   manuals should  be  submitted  via  its  respective  system. Urgent   Feedbacks An   urgent   EOSS   feedback   report   describes   a technical   discrepancy   that   could   cause   damage   to equipment   or   injury   to   personnel.   This   category   was established   to   provide   rapid   resolution   of   EOSS technical   discrepancies   related   to   genuine   operational needs. PREPARATION.—   Submit  urgent  feedbacks  by priority  message  to  NAVWARCENSSES  Philadelphia. Information  addresses  must  include  COMNAVSEA- SYSCOM  Washington,  DC,  and  your  TYCOM.  They must   contain   the   following   information: 1 . 2. 3. 4. An  urgent  EOSS  feedback  number  consisting  of the  year  and  feedbacks  sequential  position  based upon   earlier   urgent   feedbacks   you’ve   submitted that   year.   For   example,   93-2;   the   93   represents the year and the 2 shows this as the second urgent feedback  in  1993. The   code   number   of   the   EOSS   procedure(s) involved  (for  example,  BLF/O21/0585). A  detailed  description  of  the  problem.

NOTE Review  each  urgent  feedback  to  be  certain  the feedbacks  a  valid  urgent  submission  as  defined in  the  EOSS  user’s  guide. PROCESSING.—   An  urgent  feedback  report  is processed   in   the   following   manner: 1 . 2.

NAVWARCENSSES  will  provide  guidance  by message.  This  is  done  in  1  to  10  working  days depending   upon   the   complexity   of   the   issue. TYCOM   monitors   and   provides   assistance   as necessary. 1-16
