operation. In ships with more than one main engine in
the same engine room, a separate sheet is maintained for
each engine, but common entries are omitted from the
record for the port engine.
The watch supervisor enters the remarks and signs
the record for his watch. The petty officer in charge of
the engine room checks the accuracy of the record and
signs his name in the space provided on the back of the
record. The main propulsion assistant notes the contents
and signs the record. Any unusual conditions noted in
the record should be reported to the engineer officer
GAS TURBINE OPERATING RECORD
On ships with gas turbines, bells and engine
operating parameters are logged automatically by
computer. The system can produce printouts at regular
intervals or on demand. The data comes from two line
printers; one for the bell logger and one for the data
logger. The bell logger prints bell signals and replies to
those signals. The data logger prints all information
other than bell signals. The bell or data logger can print
both kinds of information if one of the loggers is
secured. Most ships use only one logger at a time.
Examples of bell and data logger printouts are logs for
data on engine parameters, alarms, status changes,
trends in operating parameters, and demand prints of
any of the logs.
DIESEL ENGINE OPERATING RECORD
The Diesel Engine Operating Record, NAVSEA
9231/2, is a complete daily record for each operating
propulsion and auxiliary diesel engine in the ship.
The watch supervisor writes and signs the remarks for
his watch. The petty officer in charge of the ships
diesel engines checks the accuracy of the entries and
signs the record in the space provided. The engineer
officer notes the contents and signs his approval of
the record daily.
AC/DC ELECTRIC PROPULSION
The AC/DC Electric Propulsion Operating Record,
NAVSEA 9235/1, is daily record for each operating
propulsion generator and motor in ships (except
submarines) equipped with ac or dc electric propulsion
machinery. A separate record sheet is used for each
shaft. Exceptions are ships with more than two
generators or two motors per shaft, where as many
sheets as required are used.
Data is entered on the record and the remarks are
written and signed by the Electricians Mate (EM) of
the watch. The accuracy of the entries is checked by
the EM in charge of the electric propulsion equipment
and the electrical officer. Space is provided on the
record for the daily approval and signature of the
BOILER ROOM OPERATING RECORD
The Boiler Room Operating Record, NAVSEA
9221/6 (fig. 2-4), is a complete record for each steaming
firercom. Space is provided on the back of the record
for the operating data of all fireroom auxiliary
machinery. Entries are checked for accuracy by the
fireroom supervisor. The B division officer also checks
and initials the record. The engineer officer checks the
entries and approves the record daily by signing it in the
space provided for his signature.
The Electrical Log, NAVSEA 9600/1 (fig. 2-5), is
a complete daily record for each operating ships
service generator, Entries for the prime movers are
generally recorded by the generator watch (MM).
Electrical data are recorded by the switchboard watch
(EM). Each signs the remarks made for his watch.
The accuracy of the entries is checked by the EM in
charge of the ships service generators. Both the M and
E division officers check the record for accuracy and
any evidence of impending casualties. Each officer
initials the record to indicate he has checked it. The
engineer officer notes the content and signs the record
daily in the space provided.
DISTILLING PLANT OPERATING RECORD
There is a distilling plant operating record for each
of the three principal types of distilling plants in use
aboard naval ships. The records are (1) the Low
Pressure Distilling Plant Operating Record, NAVSEA
9530/3, (2) the Flash Type Distilling Plant Operating
Record, NAVSEA 9530/1 (fig. 2-6), and (3) the Vapor
Compression Distilling Plant Operating Record,
NAVSEA 9530/2. Each is a complete daily record
maintained for each distilling plant in operation.
Personnel of the watch record data and remarks in the
record. The watch supervisor signs the remarks for his
watch, and the petty officer in charge of the ships
distilling plants checks all entries for accuracy and signs
the record. The division officer (M or A, as applicable)
reviews and initials the record. Space is provided on the
