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

the candidate assists in starting a main propulsion turbine engine, describing the 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. Starts the main lube-oil pump;

  2. Verifies that there is flow through the gravity tank overflow line using the sight-glass;

  3. Verifies that there is lube-oil flow to all main-engine bearings;

  4. Engages the jacking gear to the main engine;

  5. Makes notification of jacking gear status;

  6. Turns on jacking-gear motor;

  7. Establishes steam flow to the gland-seal regulator and adjusts it to recommended levels;

  8. Starts the gland exhaust condenser fan;

  9. Verifies that the main circulator high-suction and overboard-discharge valves are open;

  10. Starts the main circulator pump;

  11. Opens the main-condenser saltwater header vents until flow is observed;

  12. Verifies that main condensate pump suction and discharge stop valves are open;

  13. Verifies that main condensate pump vent line valve is open

  14. Starts the main condensate pump;

  15. Opens the inlet/outlet valves to both the first and second stage air-ejector elements;

  16. Lines up steam to the air-ejector pressure reducing station;

  17. Opens the steam root valve to the second stage main air- ejector element;

  18. Observes progressive increase in vacuum;

  19. Inspects the entire system for proper operation;

  20. Correctly describes actions as they are being performed; and

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