NVIC 07-14 Task 1.1.H(M)

Monitor jacket water evaporator (RFPEW)

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 motor vessel at sea, on a simulator, or in a laboratory,

the candidate monitors a jacket water evaporator.


Note 2 Note 6

Not performing this task will limit the candidate’s endorsement for motor and/or gas-turbine propulsion to vessels without distilling plants.

The candidate:

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