7.5.3.3 Flushing with low viscosity flushing oil
If no separator heating is available during the flushing procedure it is possible to use a low
viscosity flushing oil instead of engine oil. In such a case the low viscosity flushing oil must
be disposed of after completed flushing. Great care must be taken to drain all flushing oil from
pockets and bottom of tanks so that flushing oil remaining in the system will not compromise
the viscosity of the actual engine oil.
7.5.3.4 Lubricating oil sample
To verify the cleanliness a LO sample shall be taken by the shipyard after the flushing is
completed. The properties to be analyzed are Viscosity, BN, AN, Insolubles, Fe and Particle
Count.
Commissioning procedures shall in the meantime be continued without interruption unless
the commissioning engineer believes the oil is contaminated.
