The Enginemans duties concerning engineer-ing casualties and their control depend upon the type of ship-which may be anything from a PT boat to a carrier. An Engineman operates engines of various sizes, made by various manufacturers, and intended for different types of services. Detailed information of diesel engine casu-alty control procedures must be obtained from the manufacturers instructions, the pertinent type commanders instructions, and the ships Engineering Casualty Control Manual. Some examples of the types of engineering casualties that may occur, and the action to be taken are given below. The observance of all necessary safety precautions is essential in all casualty control procedures.

BROKEN INJECTION TIP

1. Cut out the faulty injector.

2. Notify the engineer officer and the bridge of the casualty. Request permission to secure the engine for repairs.

3. After permission has been obtained, secure the engine, remove the injector and replace it with the spare, following the procedures outlined in the appropriate maintenance manual.

4. After repairs are completed, test the engine.

When it is operating properly, report to the engineer officer and the bridge.

BROKEN CYLINDER LINER

1. Secure the engine.

2. Report to the engineer officer and the bridge. Request permission to proceed with repairs.

3. When permission is granted, remove the head and piston; pull the broken liner and replace it with the spare liner. Follow the procedure as outlined in the engine maintenance manual.

4. Make the necessary reports.

FAILED MAIN ENGINE LUBE OIL PRESSURE

1. Secure the engine immediately.

2. Notify the engineer officer and the bridge.

3. Check the sump oil level, the piping, the filters, the strainers, and the lube oil pump capacity. Make repairs.

4. After repairs have been completed, notify the engineer officer and the bridge.

WATER IN AN ENGINE CYLINDER, CRANKCASE, OR AIR PORTS

1. Notify the OOD and the engineer officer and keep them informed.

2. Do not allow the engine to be started until the cause of the casualty has been determined and corrected.

3. Check the cylinders by jacking over with

test cocks open.

4. Put pressure test on freshwater system and conduct visual inspection of the units.

5. Replace part or parts, as necessary.

6. Start the lube oil purifier to remove water from the lubricating oil.

7. After repairs have been completed, test the engine and place it back in commission.

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 of-ficer 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 con-trol 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 of-ficer and the bridge.
