LNG Steam Simulator Exercise

001. Run the Simulator to Fill the Deaerator (DFT)

[Load Snapshot "Ex_001_Procedure for filling the Deaerator (DFT)" in the Simulator]

- Asssume scenario as described below [but check to confirm] and then follow the given procedures

Electrical Power:-

Shore Power:Off; Emergency Generator:Auto Stand-by; Both Turbo Generators:Off; Diesel Generator:On

Fuel Bunkers:-

All bunker tanks are full; Fuel oil settling tanks are full as well (both for diesel oil & heavy fuel oil).

Water Bunkers:-

All water bunker tanks are full.

Both Boilers:-

Empty

Control Air System:-

On - But need to open all valves to various services. In this case, control air must be available to DFT Dump and Make Up Feed Regulators. May need to start service air compressor if control air pressure is too low. Close the relevant breaker on the Main Distribution Board.

Distilled Water Tank (DWT):-

Full (If not full to fill up deaerator at least 30%, DWT must be filled from the distiller or shore supply).

>> Procedures for Filling Up Deaerating Feed Tank (DFT):-

Main Distrib:
1 Close the ADT Pump #1 and ADT Pump #2 circuit breakers [ADT - Atmospheric Drain Tank]
Condensate:
2 Open the ADT Pump #1 Suction and Discharge Valves
3 Open the ADT Pump #2 Suction and Discharge Valves
4 Open the DFT Dump Regulator Inlet and Outlet Valves
5 Open the Make Up Feed Regulator Inlet and Outlet Valves
6 Put ADT Pump #1 into AUTO. If the ADT level exceeds 70% the ADT pump #1 will automatically start and transfer water from the ADT to the DFT.
7 If the DFT water level is below -5 inches (-125mm) then the DWT will dump water into the ADT tank via the make-up feed regulator. If the DFT water level is above +5 inches (125 mm) then the DFT will dump water into the DWT via the DFT dump regulator.
8 Wait for the DFT low water level alarm to clear.
