FOLLOWING PROCEDURES HAVE TO BE FOLLOWED BY MARINE OFFICERS ONBOARD IN CASE OF OMD ALARM-
1. Accept the alarm from the panel.
2. Inform the bridge and chief engineer and side by side initiation of slow down of engine.
3. Press engineer’s alarm to call for required manpower.
4. Check that alarm which came must not be false alarm. If it comes again after resetting then it is real.
5. Increase the lubrication of the engine by starting the standby lubrication pump.
6. Now wait for bridge to stop the engine and take the command back to engine room.
7. Indicator cock needs to be opened and close starting air valve.
Engage turning gear and start turning the engine to avoid piston getting stuck due to localised weld.

10. As a precautionary measure nobody should be standing near the crankcase relief door.
11. When the alarm will be gone, we can switch off the lube oil pump.

14. Two, three ventilation blowers should be kept for ventilation.
15. Now it is time to go inside for checks and before that make sure light should be flameproof, boiler suit is clean and free of any oil. Both sleeves should be rolled down and nothing should be in the pocket.
16. Check for any sign of local hot spot, or metal particles etc. and rectify the same.
17. Now again start the lube oil pump and check for the flow.
