The oil separation system consists of three centrifugal self-cleaning LO separators, for the separation and removal of water and solids from the LO. All separators are installed above of LO sludge tank. Together with the main lubricating oil separator is supplied with oil by an LO separator supply pump which passes the LO through a steam heater and launch panels of equipment, control modules.
Control air supplied to control the supply of oil to the bowl. Domestic fresh water supplied from the engine room service water system is provided for sealing and actuation and flushing purposes.
The separators have actuators which facilitates maintenance by having a smaller number of components, operating quieter, and vibrating less.
Two separators, marked as No.1 and No.2, the same size and performance, used for the main engine lubricating oil systems. The third separator is smaller and used for auxiliary (generator) engines and oil tank systems.
Separators can be used simultaneously for different purposes, that is, for periodic or continuous cleaning of the LO by separation. During normal operation, when ME is working, one of its LO separators must continuously clean the LO in the sump. When the engine is off, its continuously operating separator not only cleans the grease but also ensures that the LO remains warm.
The LO in the crankcase of the auxiliary generator engine is cleaned by separating it individually, the engine may or may not run during this operation.
Separators: No.1 and No.2 can clean the oil from these tanks:
✔    LO settling tank;
✔    Main Engine LO Sump Tank. Cross-connection only allows the No.2 separator to be serviced:

●  Aux Engine LO Overflow Tank;
●  Aux Engine LO Sumps.
