Question

You are the Chief Engineer on a Ro/Ro vessel powered by a MAN two stroke, direct reversing, slow speed diesel engine. While maneuvering into New York with the main engine in Bridge control status you receive low pressure alarms on both main air receivers. Both ship's main air compressors are operational and running at the time of the alarms. What should you do?

Accepted Answer

Check the air compressors to be sure they are operating correctly. Then inform the Captain on the Bridge that the starting air supply is not keeping up with demand and start air pressure should be monitored closely during the reminder of the maneuver.
