On ships that are not governed by EOSS, the
warming-up schedule is mandatory.
Securing schedules for propulsion machinery and
boilers are chronological checklists of key steps. They
are used to secure the ships main engineering plant
according to the general degree of readiness in effect.
The respective steps may be scheduled relative to the
time orders are received to secure the engine room or
boiler. The securing schedules should list the auxiliary
machinery to be used after securing the main
engineering plant. The securing schedule must be
according to the type commanders directives. A
securing schedule overcomes the normal tendency to
secure machinery too quickly. Securing schedules
should be used without regard for the experience of the
personnel involved. The engineer officer examines
completed securing schedules and disposes of them
according to the type commanders directives.
Securing schedules are not required for ships
govered by EOSS, but they are mandatory on all other
CNO and the type commanders require certain
engineering trials and inspections to determine that
standards are being met and to evaluate the operational
readiness of ships of the type. CNO and the type
commanders determine the frequency of the
engineering readiness trials and inspections.
Engineering readiness trials include full-power
trials, fuel-economy trials, and basic engineering
casualty control exercises (BECCES). BECCES serves
the same purpose as engineering operational casualty
control (EOCC) which will be discussed at the end of
this chapter. Readiness inspections include the
administrative inspection, the material inspection, and
the operational readiness inspection.
ENGINEERING READINESS TRIALS
Engineering readiness trials (full-power and
fuel-economy trials) are required by CNO and
prescribed in Ship Exercises, FXP3, and in the type
commanders directives, which contain specific
requirements for the exercises and trials. The
commanding officer conducts these trials periodically
according to those instructions. The type commander, a
commander subordinate to the type commander, or the
task force commander may assign observers for the
engineering trials. These observers will come from
another ship of the same type whenever practical. There
may be times when it is impractical to provide observers
from another ship. In those cases, personnel from the
ship conducting the trial may act as observers subject to
self-observation of trials.
The number of personnel assigned to observe
engineering trials will vary according to the trial and the
size and type of ship being observed. The duties of the
observing party are usually as follows:
. The chief observer will organize, instruct, and
station the observing party. He checks the ships draft,
either at the beginning of the trial or before leaving port;
supervises the performance of the engine-room
observers; checks the taking of counter reading; renders
all decisions according to current directives; and checks
and signs the trial report.
l The assistant chief observer helps the chief
observer as directed; supervises the performance of the
fireroom observers; checks the taking of fuel oil
soundings and meter reading; and makes out the trial
l Assistant observers review fuel soundings and
meter readings, counter readings, the ships draft, and
other data as may be required for the trial report.
The following items should be accomplished or
considered before starting the trial:
. When requested by the observing party, the ship
being observed provides a signaling system that will
allow fuel soundings and the readings of counters and
meters to be taken simultaneously.
. The ship being observed will furnish the chief
observer with a written statement of the date of last
undocking, the authorized and actual settings of all main
machinery speed-limiting devices and the status of
safety device test and inspections. The ships draft, trim,
and loading must conform to trial requirements. In case
a minimum draft is not specified, the liquid loading
should equal at least 75 percent of the full-load capacity
at the beginning of the trial.
. The chief observer determines draft and trim
before and after the trial. He verifies the amount of fuel
on board and corrects the amount to the time the trial
begins. He determines the full-power rpm required for
the displacement and injection temperature existing at
the start of the trial.
