The lubricating oil is pumped from a bottom tank by
means of the main lubricating oil pump to the lubri-
cating oil cooler, a thermostatic valve and, through
a fullflow filter, to the engine inlet RU, Fig. 8.01.01.
RU lubricates main bearings, thrust bearing, axial
vibration damper, crankpin bearings, piston cooling,
crosshead, camshaft and turbocharger bearings.
The main lube oil system is common to the cam-
shaft as well. The major part of the oil is divided
between piston cooling and crosshead lubrication.
From the engine, the oil collects in the oil pan,
from where it is drained off to the bottom tank, see
Fig. 8.06.01a and b ‘Lubricating oil tank, with cof-
ferdam’. By class demand, a cofferdam must be
placed underneath the lubricating oil tank.
The engine crankcase is vented through ‘AR’ by a
pipe which extends directly to the deck. This pipe
has a drain arrangement so that oil condensed in
the pipe can be led to a drain tank, see details in
Fig. 8.07.01.
Drains from the engine bedplate ‘AE’ are fitted on
both sides, see Fig. 8.07.02 ‘Bedplate drain pipes’.
For external pipe connections, we prescribe a
maximum oil velocity of 1.8 m/s.
Lubrication of turbochargers
Turbochargers with slide bearings are normally
lubricated from the main engine system. AB is
outlet from the turbocharger, see Figs. 8.03.01 to
8.03.03, which are shown with sensors for UMS.
Figs. 8.03.01 to 8.03.03 show the lube oil pipe ar-
rangements for different turbocharger makes.
