10 Things Deck Officer Must Know While Operating Main Engine From Bridge

In this article, we will be discussing them in further detail with regards to main engine’s interlocks, starting procedure, resetting and fault finding.

Mentioned below are some additional important points that deck officers must consider while operating marine engine from bridge:

1. Constantly Monitor Engine Load In Rough Weather: While operating in rough weather and heavy weather areas, engine load should be constantly monitored. Stern swell often causes the propeller to emerge out of water for fraction of seconds during the time period of swell. Thus a reduction in resistance near the propeller results in racing of the propeller and a surge in the load on the main engine.

2. If Remote Control Fails, Transfer Control To Engine Room Immediately: If remote control operation becomes inoperative or unavailable by accident, the control position should be immediately changed or transferred to the engine side. Control cannot be changed over if start air main valve is not in service mode or auxiliary blower is not in auto position.

3. If Main Engine Stops, Move Manoeuvring Handle To STOP Position: If main engine stops due to emergency shutdown or automatic shutdown device, always first move the manoeuvring handle in control to STOP position to ensure the safety of the vessel. In case of failure of the remote control system, manual and automatic shutdown devices are provided to enable shutdown of the engine in case of any abnormality.

4. To Reset Emergency Shutdown, The Telegraph Transmitter On The Bridge Must Be Put To STOP Position: In case of an automatic emergency shutdown it must be borne in mind that main engine is automatically shutdown by fuel cut-off due to overspeed, low lube oil pressures, high temperatures of thrust pad. For resetting an emergency shutdown the telegraph transmitter on the bridge must be put into STOP position and Emergency stop button should be pressed in the control room to reset it.

5. Auto Emergency Slow Down Alarm Can be Cancelled To Keep Engine Running: AUTO EMERGENCY SLOW DOWN ALARM for the main engine functions similar to the AUTO EMERGENCY SHUT DOWN and thus same can be cancelled if required by the circumstances, which keeps running the engine as per telegraph order and does not slow it down.

6. Check Start Air Valve or Auxiliary Blower Position In Case Of Alarm While Changing Over The Engine Controls From Control Room: While changing over the engine controls from control room to bridge if any difficulty or alarm is observed, it can be mostly due to inappropriate position of start air main valve or auxiliary blower in any other position other than AUTO.

7. Imperfect Bridge Control Condition Alarm is Mainly Due To Inappropriate Position Of Start Air Main Valve Or Auxiliary Blower: If there is an alarm IMPERFECT BRIDGE CONTROL CONDITIONS, it can be mostly due to inappropriate position of start air main valve or auxiliary blower in any other position other than AUTO or due to abnormal condition of bridge control air pressure. While stopping and starting main engine it must always be kept in mind that a limited number of starts can be made with the charged air bottles for start air.

8. Follow All Steps While Removing Starting Interlock For Main Engine Fuel Oil Supply: For removing starting interlock for Main Engine fuel oil supply to be restored, turning gear should be disengaged and emergency shutdown should be in operational state. This is a safety feature provided in the main engine to prevent any operational mistakes while starting the main engine.

9. Miss Ignition Restarting Take Place Automatically: When main engine keeps running for a preset time between lower and upper limits of critical speed range the alarm CRITICAL SPEED RANGE will light up. The term MISS IGNITION is used when the main engine speed drops lower than ignition level speed after the main engine is changed into fuel running. For miss ignition restarting will be automatically made. The indicator lamp REPEATED START lights up during restarting.

10. Be Careful If Main Engine Is Set To Limited Revolution Value: If main engine is set to limited revolution value by a ten key in Control Room Control Panel, then the engine can be accelerated not more than the upper limit of the set revolution in case of bridge control. In such case if telegraph transmitter from the bridge is moved to more than the position for limited revolution the indicator LIMITED SPEED lights up.
