In order to satisfy NVIC 17-14 Task 4.3.F , MMA students must:

NVIC Method

See NVIC method.

STCW Competence Knowledge, Understanding, and Proficiency

Operate main and auxiliary machinery and associated control systems

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

the candidate assists in securing a main propulsion diesel engine, describing actions as they are being performed.


Note 5 A candidate who does not perform this task will receive an endorsement that is not valid for motor vessels.

The candidate:

  1. At “Finished With Engines,” coordinates with bridge to shift main engine from bridge control to engine-room control;

  2. Changes over and verifies that change in control has occurred;

  3. Secures fuel-oil supply and booster pumps, (if fitted) and acknowledges low-pressure alarm;

  4. Closes air start blocking valve;

  5. Closes air receiver outlet valves to air start system;

  6. Opens each cylinder indicating cock;

  7. Engages engine-turning gear;

  8. Starts engine-turning gear and cycles through one revolution;

  9. Secures main lube-oil system supply pumps and acknowledges low-pressure alarm;

  10. Secures jacket fresh cooling water supply pump and acknowledges low-pressure alarm;

  11. Secures power to alarm and instrumentation panel;

  12. Secures cooling medium supply valves to intercooler;

  13. Opens air box drain valves, scavenging air receiver drain valve, or charge air manifold drain valves, as appropriate;

  14. Line up main engine cooling water system to keep main engine warm while secured in support of vessel operational requirements; and

  15. Enters the time that all systems were secured in logbook.
