NVIC 07-14 Task 1.1.H(S)

Monitor steam distilling plant

NVIC Method

Show NVIC method.

STCW Competence Knowledge, Understanding, and Proficiency

Carry out a watch routine appropriate to the duties of a rating forming part of an engine-room watch.

RFPEW-A1.2 Engine-room watchkeeping procedures
Condition Behavior Standard

On a steam vessel at sea or at anchor in clean water, on a simulator, or in a laboratory,

the candidate monitors steam distilling plant.


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. Checks plant’s operational status;
  2. Checks sea-water feed, brine, distillate, and condensate drains pump suction and discharge pressures as appropriate;
  3. Checks air-ejector steam supply pressure;
  4. Checks sea-water feed inlet temperature;
  5. Checks distillate outlet temperature;
  6. Checks shell vacuums;
  7. Checks feed-water-heater inlet pressure and temperature;
  8. Verifies and checks distillate-pump discharge to proper tank;
  9. Observes the position of the 3-way valve to ensure it is not tripped, unless in the case of high distillate salinity;
  10. Takes water-meter reading;
  11. Checks distillate salinity; and
  12. Notifies the watch engineer of any unusual or unsafe conditions
