c. Dual Station Throttle Control . The dual station throttle control system
provides pneumatic direction and throttle control for the main propulsion engines
from the PHC and ERC, and the bowthruster/auxiliary fire pump engine from the PHC
only.
(1) Main propulsion engine control. The
system provides two throttle and
direction control valves at both the PHC and the
ERC. The ERC contains a pilot air
valve for ERC control of the system or transfer
of control air to the PHC. The PHC
contains a pushbutton air valve for control air
at the pilothouse.
(2) Bowthruster/auxiliary fire pump engine control. The PHC contains a
throttle control air valve for bowthruster/auxiliary fire pump selection. Selection
results in engaging the appropriate power take-off (PTO). The valve also provides
throttle control for the engine.
d. Machinerv Plant Monitoring System. The machinery plant monitoring system is
a microcomputer based system which monitors vital machinery operating conditions.
The system consists of the engine room console panel and a color video cathode ray
tube (CRT) display on the engine room console and the bridge console panel and color
video CRT display located on the pilot house console. The CRT displays date and
time, alarm messages, and monitored status. The monitored status is presented in
seven pages of displays.
(a) Page 1 - Machinery Plant Control System.
Provides a table of contents
for the system.
(b) Page 2 - Engine Summary. Displays oil pressure, water temperature,
stack temperature, and RPM for both port and starboard main engines.
(c) Page 3 - Engine Summary. Provides oil temperature and oil differential
for both port and starboard main engines and also displays left and right main
engine bank temperatures for both main engines.
(d) Page 4 - Generator Summary. Displays oil pressure, water temperature,
oil temperature, and stack temperature for the port and starboard SSDG engines.
(e) Page 5 - Reduction Gears. Provides oil pressure and oil temperature for
the port and starboard reduction gears.
(f) Page 6 - Bowthruster Engine.
Displays oil pressure and water
temperature for the bowthruster engine.
(g) Page 7 - Fire Pump/Main. Provides indication of valve position for main
and emergency system, control air pressure, and start air pressure for the port and
starboard main engines and SSDG number 2.
(1) Engine room console panel. The engine room console panel provides a
centralized engine room location for starting and stopping the bilge/ballast pump,
fresh water makers, fresh water pumps, fire pumps, ship's service diesel generators,
and main propulsion engines. Indicator lamps are provided for run condition display
of other equipment, control station in operation (PHC or ERC), dead man alarm, and
engineers-assistance-needed pushbuttons. The panel also provides controls for the
CRT display and audible alarm.
