LNG Steam Simulator Exercise


016. Run the Simulator to Start the Main Turbine Lubrication System

[Load Snapshot "Ex_016_Changing Over from DO to HFO_Burning"]

- 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; Turbo Generators:One on load and the other off; Diesel Generator:On Load

Deaerator:-

Full with guage glass reading between 60~70 mm

Both Boilers:-

Both Boiler Press - aboout 6 Mpa; Both boilers are running on HFO supply.

Condenser:-

Condenser Vacuum is Satisfactory and Cooling on

Distilled Water Tank (DWT) & Atmospheric Drain Tank (ADT):-

Both DWT & ADT about 60% full.

>> Procedure for preparing the Lubricating Oil System:-

Emerg Distrib:
1 Close the Lube Oil Pump #1 circuit breaker
Main Distrib:
2 Close the Lube Oil Pump #2 circuit breaker
LO Purifier:
3 Open the LO Pump #1 Suction and discharge valves
4 Open the LO Pump #2 Suction and discharge valves
5 Open the LO Cooler Inlet and Outlet Valves
6 Start LO Pump #1
7 When LO Pressure reaches its rated operating value, the LO Pressure alarm should clear
8 Put LO Pump #2 into Standby Operation.
9 The LO Gravity tank fills and will overflow back to the sump at around 90% capacity. The Sight-Glass will turn yellow indicating a passage of oil in the overflow pipe.
