Monitor main propulsion boiler

MMA Method

In order to satisfy NVIC 07-14 Task 3.1.C , MMA students must:

NVIC Method

See NVIC method.

STCW Competence Knowledge, Understanding, and Proficiency

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

RFPEW-A2.1 Safe operation of boilers
Condition Behavior Standard

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

the candidate monitors the main propulsion boiler.


Note 1 Not performing this task will limit the candidate’s endorsement to motor and/or gas-turbine propelled vessels only.

This task is not required for steam propulsion and no limitation will be placed on the steam vessel endorsement if this task is not completed.

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.
