RFPEW Task 1.1.G

Charge a potable water pressure tank with compressed air

In order to satisfy NVIC 07-14 Task 1.1.G , MMA students must:

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 vessel, on a simulator, or in a laboratory,	the candidate charges a “waterlogged” potable water pressure tank with compressed air. All The assessment applies to all RFPEW endorsements.	The candidate: Correctly connects the compressed air hose from the service air header to the pressure tank; Opens the appropriate valves, charge air into the pressure tank, while observing the water level and allowing the potable water pump to cycle on and off; Closes the appropriate valves, secure from charging air into the pressure tank when the potable water pump no longer short- cycles and the pressure tank level cycles between normal parameters; Correctly disconnects and stow the compressed air hose from the service air header to the pressure tank; and Takes proper action to prevent safety and pollution violations.
