NVIC 17-14 Task 4.3.I

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

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.

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.
