8.
Transformers (figure 1, item 8). Three 440V/120V transformers provide 120V power for the load center distribution
panel.
9.
Lube oil transfer pump (figure 1, item 9). The lube oil transfer pump is an electrically powered pump used to transfer
lube oil within the vessel.
10. Lube oil transfer pump discharge pressure gauge and the lube oil transfer strainer differential pressure gauge (figure 1,
item 10). The lube oil transfer pump pressure gauge indicates the discharge pressure of the lube oil transfer pump. The
lube oil transfer strainer differential pressure gauge indicates the differential pressure of the strainer.
11. Lube oil manifold (figure 1, item 11). The lube oil manifold provides centralized control of the lube oil piping system.
12. Lube oil transfer pump motor controller (figure 1, item 12). This controller turns the lube oil transfer pump ON and
OFF.
13. Lube oil tank level indicator and hand pump (figure 1, item 13). The tank level indicator displays the amount of oil
present in the tank. The hydraulic oil hand pump is used to transfer hydraulic oil from the hydraulic oil storage tank.
14. Ship's Service Diesel Generator (SSDG) 2 starting air pressure gauge (figure 1, item 14). This gauge indicates the
amount of pressure available to the SSDG 2 starter.
15. SSDG 2 (figure 1, item 15). SSDG 2 is an air-started, fresh water-cooled, diesel engine-driven service generator
providing electric power to the main switchboard.
16. Air receiver (figure 1, item 16). The 30 gallon (113.6 liter) air receiver stores air for the control air system.
17. Sewage discharge pump 2 (figure 1, item 17). Sewage discharge pump 2 is an electrically powered pump that pumps the
contents of the sewage tank to the sewage shore connection or overboard.
18. Control air dryer (figure 1, item 18). The control air dryer removes moisture from the control air system.
19. Sewage discharge pump 2 motor controller (figure 1, item 19). The sewage discharge pump 2 motor controller turns
sewage discharge pump 2 ON and OFF.
20. Sewage discharge pump 2 pressure gauge (figure 1, item 20). This pressure gauge indicates the discharge pressure of
sewage discharge pump 2.
21. Engine room distribution panel no. 4 (figure 1, item 21). The engine room distribution panel provides power distribu-
tion for engine room equipment.
22. Monitoring system Central Processing Unit (CPU) with 24 volt machinery DC control distribution panel (below) (fig-
ure 1, item 22). The monitoring system CPU cabinet contains the central processor for the machinery plant monitoring
system. A 24 volt machinery DC control distribution panel provides circuit protection for machinery monitoring,
SSDG. 2, FM-200 shutdown, rudder angle, steering gear alarm, pump drive engine, and bow thruster engine.
23. Fire extinguisher (figure 1, item 23). The fire extinguisher is used to extinguish small fires.
24. Engine control panel (figure 1, item 24). This panel provides the controls and status displays for the main engines.
25. Engine alarm horn (figure 1, item 25). The engine alarm horn sounds the engine alarm, indicating various engine
conditions and emergencies.
26. Lube oil prime pump and controller (figure 1, item 26). The lube oil prime pump primes the main propulsion engine for
operation. Its controller also operates the lube oil pump, permitting the operator to select ON and OFF.
27. Fire station 2 (figure 1, item 27). The firefighting station uses raw water and is equipped with 50 feet (15.24 m) of 1-1/2
inch hose and an all-purpose nozzle.
