MAIN PROPULSION ENGINES
1.
Ensure Port and Starboard main engine and reduction gear lube oil sumps and fresh water cooling systems
are at the proper operating levels.
2.
Ensure Port and Starboard main engine governor oil levels are at the proper operating level.
3.
Open Port and Starboard main engine air box drains to remove any oil that may have accumulated. Close
drains.
4.
Check intake air filters for dirt and obstructions.
5.
Ensure power is available to the reduction gear cooling pumps, main engine pre-lube pumps and main
engine control panels.
6.
Align main engine pre-lube systems by opening valves LO-47 and LO-48 and pre-lube engines for five
minutes if engines have been shut down for twelve hours or longer. Do not exceed five minutes with valves
open as oil will enter valve seats.
7.
Align cooling water system by opening valves FWC-2, FWC-4, FWC-14, FWC-16, for port main engine
and reduction gear and FWC-3, FWC-I, FWC-15 and FWC-13 for stbd main engine and reduction gear.
Start reduction gear cooling pumps.
8.
Ensure adequate supply of fuel oil is available in day tanks and open valves FO-15, FO-20 and F0-35 for
stbd main engine taking suction from and returning to stbd day tank or valves FO-13, FO-14, FO-20, F0-
34 and FO-33 for stbd main engine taking suction from and returning to the port day tank. Open valves F0-
13, F0-19 and F0-33 for port main engine taking suction from and returning to port day tank or valves F0-
15, F0-14, FO-19, FO-34 and FO-35 for port main engine taking suction from and returning to stbd day
tank.
9.
Ensure that diesel starting air receivers are charged and that starting air system to port and stbd main
engines is lined-up by opening valves CA-1, CA-2, CA-3, CA-4, CA-12, CA-8 and CA-9.
10. Ensure that propulsion control air receiver is charged, air dryer is running and propulsion control system
is set up for normal operation with propulsion control from EOS station and port and stbd main engine
throttles in the neutral position.
11. Ensure that alarms are cleared on local control panels.
12. Ensure that governors emergency stops are pulled out.
13. Momentarily press engine start push-button on engine control cabinet to start turbo oil pump (allow turbo
oil pump to run at least 60 seconds before starting engine).
14. Blow down cylinders to remove accumulated moisture by opening indicator cocks and rotate engine slowly
(engine may be rotated by manually depressing starting solenoid valve while throttling air with engine
mounted ball valve). Close indicator cocks after completion.
15. Push in governor emergency stops and ensure that overspeed trips are in the run position.
16. Start engine by depressing the start button on the local control panel or by pressing the remote start button
in the EOS. Release start button after engine starts.
