the candidate assists in starting a main propulsion gas turbine engine, describing the 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. Ensures the enclosure is secure;

  2. Ensures that the starting medium is available and at recommended pressures;

  3. Ensures all permissive obligations are met, including:

    a. Reduction gear oil at pressure;

    b. Jacking gear disengaged;

    c. Clutch disengaged (if so fitted);

    d. Gas generator speed below alarm point;

    e. Uptake and supply stacks are clear;

    f. Command throttles are in the IDLE position;

    g. Command and Control logic is reset;

  4. Initiates starting sequence from command platform;

  5. Monitors all speeds, temperatures and pressures vital to engine start;

  6. Ensures start medium and ignition system are secured upon reaching gas generator idle speed; and

  7. Records start initiation and at idle times.
