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 gas turbine vessel of at least 1,000 HP, on a simulator, or in a laboratory,

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


Note 4 A candidate who does not perform this task will receive an endorsement that is not valid for gas-turbine propelled vessels.

The candidate:

  1. Checks enclosure for fire, lighting, vibration;

  2. Monitors necessary operational parameters, including:

    a. Reduction gear oil supply pressure and bearing temperatures;

    b. Power turbine and gas generator speeds and vibration levels;

    c. Compressor inlet and discharge temperatures and pressures;

    d. Power turbine inlet temperature and pressure;

    e. Gas turbine bearing lube oil temperatures; and

    f. Exhaust gas temperature and pressure;

  3. Performs performance calculations and compares results with ideal mapping data; and

  4. Determines necessary changes to operational procedures or status.
