Main engine lubricating oil system
This system supplies lubricating oil to the engine bearings, and cooling oil to the pistons. Lubricating oil is pumped from ME LO Circulating Tank, placed in the double bottom beneath the engine, by means of the ME LO Pump, to the ME LO Cooler, a thermostatic valve, and through a full-flow filter, to the engine, where it is distributed to the various branch pipes. Pumps and fine filters are arranged in duplicate, with one as a standby. From the engine, the oil collects in the oil pan, from where it is drained to the ME LO Circulating Tank for reuse. A centrifuge is arranged for cleaning the lubricating oil in the system and the clean oil can be provided from a storage tank.
