CHAPTER 9 ENGINEERING CASUALTY CONTROL INOPERATIVE SPEED GOVERNOR
1. Control the engine manually, if possible.
2. Notify the engineer officer and the bridge, and request permission to secure the engine for repairs.
3. When permission has been obtained, check the governor control mechanism.
4. Check the linkage for binding or sticking.
5. Check the lubrication; flush and refill with proper oil.
6. Check setting of needle valve.
7. Make repairs. When they are completed, start the engine and check its operation. When it is operating properly, notify the engineer officer and the bridge.
LOST FUEL OIL PRESSURE
1. Notify the bridge.
2. Check the entire fuel system, including strainers, filters, and valves. Check the amount of fuel in service tanks, fuel lines, pumps, and relief valves until the trouble is found.
3. Make necessary repairs and test the engine.
4. Place the engine back in commission when the troubles are corrected.
ABNORMALLY HIGH LUBE OIL TEMPERATURE
1. Check the lube oil pressure.
2. Check the saltwater dump discharge pressure and the temperature of the cooling water.
3. Check the freshwater level in the expansion tank and the temperature of the freshwater.
4. Check the sea suction and the overboard valves.
5. Vent the freshwater and the saltwater pumps.
6. Check the operation of the thermostat control valve to the lube oil and freshwater heat exchanger.
7. Report any trouble found to the engineer officer and the bridge. Request permission to secure the engine for repairs.
8. When permission is received, make repairs.
9. After repairs are completed, check the engine and, after it is operating properly, report to the engineer officer and the bridge.
ENGINE COOLING WATER TEMPERATURE ABOVE THE ALLOWED LIMIT
1. Notify the bridge.
2. Reduce the load and the speed of the engine.
3. Check the freshwater level in the expansion tank.
4. Check the saltwater discharge pressure.
5. Check the sea suction and the discharge valves.
6. Vent the freshwater and the saltwater pumps.
7. Check the setting and operation of the temperature regulating valve.
8. If conditions warrant securing the engine at any time, secure and notify the bridge and the engineer officer.
9. Make repairs, test out the engine, and, if it is operating properly, notify the engineer officer and the bridge.
FUEL OIL CASUALTIES
In addition to casualties which may involve parts of the fuel oil system within the engine, other casualties may occur which involve the system out-side of the engine. Examples of some of the possible casualties, along with the action to be taken follow:
WATER IN DIESEL FUEL OIL SERVICE (DAY) TANK
1. Shift fuel oil suction.
2. Notify the engineer officer and the bridge of the casualty.
3. Drain the water from all filters, strainers, and lines.
4. Open all test cocks on the engine, and turn the engine over until assured that the system is free of water.
5. Close the test cock. Start the engine. Check its operation. If operation is normal, notify the engineer officer and the bridge that the engine is ready for normal operation.
6. Strip or drain the contaminated service tank and refill with clean fuel using the fuel oil purifier.
INOPERATIVE DIESEL FUEL OIL TRANSFER PUMP
1. Line up the diesel purifier to supply the tank as quickly as possible.
2. Notify the engineer officer of the casualty.
3. In an emergency, line up and use the hand-operated pump in order to continue operation.
4. At the earliest possible time, inspect and repair the fuel oil transfer pump.
5. Report the results of the investigation and repairs to the engineer officer.
HYDRAULIC COUPLING CASUALTIES
Coupling casualties vary with each installation. The following examples, and the action to be taken, are applicable to some Fairbanks-Morse marine installations.
FAILURE OF THE MAIN LUBE OIL PUMP
1. Start the standby pump or the lube oil transfer pump and cut in on the line.
2. Cross-connect the twin hydraulic coupling systems.
3. Notify the engineer officer and the bridge of the casualty and the emergency measures taken.
4. At the earliest possible time, repair the hydraulic lube oil pump.
5. Report the repairs completed to the engineer officer and the bridge, and request permission of the engineer officer to start the pumps.
INOPERATIVE PROPELLER SHAFT PNEUMATIC BRAKE
1. Report the casualty to the bridge and the engineer officer.
2. Check the air pressure to the brake.
3. Check the air reducing valve to the brake.
4. Check the electrical and pressure control switches to the air control valve.
5. If the trouble is not determined and the use of the engine is required, do the following:
a. Secure the air to the brake system until proper inspection of the brake shoes and expansion core can be made.
b. Notify the bridge and the engineer officer that the engine is being operated without the brake, and that the throttle alone is being used for control.
c. Use extreme caution during the operation.
d. At the earliest possible time, inspect and repair the brake.
e. Report the repairs to the engineer
officer.
INOPERATIVE COUPLING LUBE OIL REGULATING VALVE
1. Maintain the correct operating pressure by manually operating the clutch dump valve.
2. Report to the engineer officer and the bridge. Request permission to secure the engine to effect repairs.
3. When permission is granted, replace or repair the valve.
4. Test for proper operation.
5. If the valve is operating properly, report to the engineer officer and the bridge.
OVERHEATING COUPLING
1. Check the system to determine the cause of
