Water Bunkers:-

All water bunker tanks are full.

Both Boilers:-

Empty

Control Air System:-

>> Procedures for Filling Up both Boilers:-

Emerg Distrib:
1 Close the Emergency Feed Pump circuit breaker
T/bines and Feed:
2 Open the Emergency Feed Pump Suction and Discharge Valves
Port/Stbd Boiler:
[It is recommended that one boiler is filled first (before the second) so that water level may be monitored.]
3 Open Auxiliary Feed Stop Valve.
4 Open Auxiliary Feed Valve about 50%
5 Open Boiler Air Vent Valve
T/bines and Feed:
6 Start the Emergency Feed Pump
Port / Stbd Boiler:
7 Allow the boiler to fill to a level of approximately -4 inches (-100mm) then close a valve on the Auxiliary Feed line.
