NVIC 07-14 Task 3.1.C

For keeping a safe boiler watch: Maintain the correct water levels and steam pressures

RFPEW-A2.1 Safe operation of boilers

On a steam vessel, on a simulator, or in a laboratory,

the candidate monitors the main propulsion boiler.

The candidate:

1. Monitors the steam drum pressure and water level, with water level being taken at both the gauge glass and remote level indicator;
2. Monitors superheater and de-superheater outlet pressures and temperatures;
3. Monitors feed water pressure and temperature;
4. 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;
5. Monitors the fuel oil settling/service tank levels and temperatures;
6. Strips fuel oil settling tanks of moisture as appropriate;
7. Monitors forced draft damper position and combustion air pressure and temperature;
8. Monitors stack temperature;
9. Monitors atomizing steam pressure as applicable;
10. Observes stack gases leaving boiler through periscope;
11. Monitors flue gas analysis readings as applicable;
12. Monitors boiler water analysis readings as applicable;
13. Observes condition of flame through peephole and checks for the presence of clinkers;
14. Visually inspects boiler casing, hand holes, manholes, and piping for leaks;
15. N the watch engineer of any unusual or unsafe conditions, unusual sounds, or vibrations; and
16. 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.
