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 systems

Steam boiler and associated auxiliaries and steam systems

Condition Behavior Standard

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

the candidate monitors the oil-fired or waste heat auxiliary boiler.


Note 3

A candidate who does not perform this task will receive an endorsement that is limited to motor and/or gas-turbine propelled vessels without waste-heat or auxiliary boilers.

The candidate performs either (A) or (B):

(A) OIL-FIRED AUXILIARY BOILER

  1. Monitors the steam drum pressure and water level;

  2. Monitors the feed water pressure;

  3. Monitors the fuel oil service pump suction and discharge pressures and fuel-oil supply pressure and temperature to the supply header and applicable fuel oil strainer pressure drops;

  4. Monitors the fuel oil settling/service tank levels and temperatures;

  5. Strips fuel oil settling tanks of moisture as appropriate;

  6. Monitors the stack temperature;

  7. Monitors the atomizing steam pressure as applicable;

  8. Observes condition of flame through peephole;

  9. Visually inspects boiler casing, hand holes, manholes, and piping for leaks;

  10. Promptly wipes up any oil accumulations presenting a fire hazard

  11. Notifies the watch engineer of any unusual or unsafe conditions, unusual sounds, or vibrations; and

  12. Takes proper action to prevent safety and pollution violations. NOTE: Recorded readings from analog gauges should be ± 5% of actual, except boiler water level should be ±1” of actual.

The candidate performs either (A) or (B):

(B) WASTE HEAT AUXILIARY BOILER

  1. Monitors the steam drum pressure and water level;

  2. Monitors the feed water pressure;

  3. Monitors the feed pump suction and discharge pressures;

  4. Monitors the feed tank level and temperature;

  5. Monitors the boiler water circulating pump suction and discharge pressures, as applicable;

  6. Monitors the exhaust gas inlet temperature

  7. Monitors the stack temperature;

  8. Visually inspects boiler casing, hand holes, manholes, and piping for leaks;

  9. Notifies the watch engineer of any unusual or unsafe conditions, unusual sounds, or vibrations; and

  10. Takes proper action to prevent safety and pollution violations. NOTE: Recorded readings from analog gauges should be ± 5% of actual, except boiler water level should be ±1” of actual.
