4.4.6 Maintenance and treatment of lubricating oil
It is essential that engine lubricating oil is kept as clean as possible. Water and
solid contaminants held in suspension are to be removed using centrifugal sep-
arators which operate in bypass to the engine lubricating system.
Great care has to be taken of the separators and filters to ensure that they work
correctly. The separators are to be set up as purifiers and completely isolated
from the fuel oil treatment systems; there must be no possibility of cross-contam-
ination.
Oil separator
Oil samples
To ensure that representative samples of lubricating oil can be taken, dedicated
sampling points (cocks) are provided on engine side. Such cocks need also to be
installed on system side according to the relevant system proposal drawing in
MIDS.
Type Self-cleaning centrifugal separator
Min. throughput capacity [l/h] Refer to GTD.
Rated separator capacity The rated or nominal capacity of the separator is to be ac-
cording to the separator manufacturer’s recommendations.
