SYSTEM OPERATION
The lubrication oil fill and transfer system transfers lubricating oil from the lube oil storage tank to the main engine, SSDG
sumps, bow thruster engine sump, and pump drive engine sump. System alignment is maintained by the lube oil transfer
manifold (3-way manifold) (figure 1, item 2) and a combination of valves. A fast lube oil drain system allows dirty oil and
sludge to be discharged from the engine sumps to the oily waste drain tank (figure 1, item 5) using gravity drains. Dirty oil
from the port and starboard reduction gears is discharged to the oily waste drain tank using the lube oil hand pump (figure 1,
item 9). Power for the lube oil transfer pump is supplied from the main switchboard, through 440V power panel No. 1. A
lube oil purifier (figure 1, item 1) purifies the lube oil for the main engines. Power for the lube oil purifier is supplied from
main switchboard. Each unit has a START/STOP pushbutton adjacent to the unit.
