after the inspection is complete and includes only those deficiencies  that  are  considered  to  be  important  to  the top  levels  of  OPNAV  and  to  fleet  and  type  commanders. He sends copies of the report to the appropriate fleet and type  commanders  and  other  interested  commands, bureaus, and offices of the Department of the Navy. If the inspecting board believes the condition of the ship  reflects  credit  or  discredit  upon  any  officer attached to the ship, that opinion is sent in a separate letter to the officer’s reporting senior with a copy to the officer   concerned. INSURV Surveys Whenever  CNO  considers  a  ship  to  be  unfit  for further  service  because  of  its  material  condition, obsolescence,  or  other  reasons,  INSURV  conducts  a survey of the ship. After a thorough inspection, the board sends an opinion to the Secretary of the Navy as to whether the ship is fit for further naval service or can be made so at reasonable cost. If the board believes the ship is unfit for further service, and the cost of repairs or  modernization  is  excessive,  the  board  recommends that the ship be disposed of according to applicable law. ENGINEERING  OPERATIONAL SEQUENCING  SYSTEM  (EOSS) The  EOSS  is  a  complete  set  of  technically  correct, properly sequenced, operational and casualty control procedures  developed  for  each  ship  type  and configuration.  OPNAVINST  9200.3  establishes  EOSS as  the  basic  guide  for  propulsion  plant  operations  and casualty  control.  It  further  defines  responsibility  for  the system’s development, review, distribution, training, installation,  use,  monitoring,  and  updating. EOSS  standardizes  operational  techniques  for watch  standers  and  casualty  control  practices.  A qualified watch stander can use the system to align, start up, operate, and secure propulsion plant equipment during  normal  operations  and  casualty  conditions. EOSS consists of the procedures, charts, diagrams, and reference documents necessary to accomplish major steady-state changes in the propulsion plant and to respond to the most frequently occurring casualties. EOSS   is   divided   into   two   major   subsystems: Engineering  Operational  Procedures  (EOP)  and Engineering Operational Casualty Control (EOCC). Both are discussed in greater detail later in this chapter. EOSS  includes  the  procedures  necessary  for  each ship  to  proceed  from  shore  services  (cold  iron)  to auxiliary operation, to under way, back to auxiliary operation,  and  back  to  shore  services.  Each  EOSS package  includes  procedures  and  tank  tables  to  transfer fuel oil internally and to refuel, defuel, ballast, and deballast  all  engineering  propulsion  plant  fuel  tanks. EOSS l l l also  provides  the  following  advantages: Uniform  operating  criteria  throughout  the  fleet Effective   use   of   available   personnel   and equipment  to  standardize  EOPs  and  EOCC practices Document   procedures   for   normal/casualty operation  and  training  support ENGINEERING  OPERATIONAL PROCEDURES (EOP) The EOP section of EOSS is a set of standardized, technically  correct,  written  procedures  for  the  normal operation of a ship’s engineering propulsion plant. EOP documents list the steps and systems alignment required for normal engineering plant evolutions. EOP does not address  abnormal  systems  alignments  or  those  required for maintenance, battle damage, or other specialized evolutions.   EOP   is   detailed   enough   to   provide directions to a watch stander who can use it to perform operations   without   deviation   from   the   written document. It is necessary to develop EOP parameters because of  the  large  number  of  equipment  combinations,  plant alignment  configurations,  and  steaming  conditions  in an engineering propulsion plant. The EOP is developed using the following parameters: .  All  equipment  is  fully  operational  within  design operating  limits. . All watch areas are manned by qualified watch standers. . Only authorized ship alterations are recognized. . Valves are labeled according to the SIB. The   EOP   must   contain   the   following documentation: master prelight-off checklist, master plant procedures, operational procedures, equipment status charts, optimum generator combination chart, valve  status  diagrams,  system  procedures,  component procedures, system diagrams, oil king procedures, tank tables, EOP Record of Revisions Page, and EOP Index. 4-13
