OICEW-A4.3 Preparation, operation, fault detection and necessary measures to prevent damage for the following machinery items and control system

Main engine and associated auxiliaries
Condition Behavior Standard

On a steam vessel of at least 1,000 HP, on a simulator, or in a laboratory,

the candidate plans for and monitors an operating main steam turbine engine, describing actions as they are being performed.


Note 1 A candidate who does not perform this task will receive an endorsement that is not valid for steam vessels.

The candidate:

  1. Checks all main-engine and reduction-gear bearing thermometers to detect signs of overheating;

  2. Checks oil sight-flow indicators for proper oil flow

  3. Checks the clearance indicators for proper rotor position;

  4. Checks all thermometers, pressure gauges, and vacuum gauges

  5. For readings within operating ranges;

  6. Checks the oil level in the main sump;

  7. Maintains the proper water level in the de-aerating feed tank;

  8. Constantly monitors the salinity indicators;

  9. Checks the lube-oil temperature from the lube-oil cooler, and

  10. Maintains at proper temperature;

  11. Checks the pressure of the cooling-water main;

  12. Properly responds to and logs all speed change orders;

  13. Is constantly alert for unusual sounds and/or vibrations;

  14. Correctly describes actions as they are performed; and

  15. Takes proper action to prevent safety and pollution violations.
