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 officers reporting senior with a copy to the
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.
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
systems 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.
also provides the following advantages:
Uniform operating criteria throughout the fleet
Effective use of available personnel and
equipment to standardize EOPs and EOCC
Document procedures for normal/casualty
operation and training support
The EOP section of EOSS is a set of standardized,
technically correct, written procedures for the normal
operation of a ships 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
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
. All watch areas are manned by qualified watch
. 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.
