Coupling casualties vary with each installa-tion. 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 per mission 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 expan-sion 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 overheating.

2. Regulate the valves manually to maintain proper operating temperatures.

3. Notify the engineer officer and the bridge. If it is necessary to secure the engine to effect repairs, request permission.

4. When permission is granted, secure the engine and effect repairs.

5. Upon completion of repairs, notify the engineer officer and the bridge.

COUPLING THROWING OIL

1. Check the system. Attempt to repair the leak.

2. Report to the engineer officer and the bridge. If the leak is not repaired, request per-mission to secure the engine for repairs.

3. When permission is granted, secure the engine, conduct an investigation, and make necessary repairs.

4. Upon completion of repairs, test the coupling.

5. Report to the engineer officer and the bridge.
