4.4.1 Lubricating oil requirements
The validated lubricating oils were selected in co-operation with the oil suppliers.
In their respective product lines the products are considered as appropriate lubri-
cants for the application indicated.
WinGD does not accept any liability for the quality of the supplied lubricating

4.4.2 Main lubricating oil system
Field of application
Lubrication of the main bearings, thrust bearings and bottom-end bearings is car-
ried out by the main lubricating oil system. The main lubricating oil system also
operates the cooling of the piston crown with the efficient jet-shaker principle
and the lubrication and cooling of the torsional and axial vibration dampers.
Figure 4-14 shows the general installation principle.
Lubrication of
crosshead bearings
The crosshead bearings are lubricated by an additional crosshead pump (specifi-
cation see Booster pump for crosshead lubrication,  4-25).
