3.8 LUBRICATING OIL & HYDRAULIC FLUID

Use of the correct grade of lubricating oils and hydraulic fluids and maintaining them in a serviceable condition is of vital importance to the well-being of a vessel’s plant and machinery.

It is the Technical Assist responsibility to ensure that analysis is being carried out at the intervals specified in the Fleet Operations Procedures Manual and that the analysis reports are received from the suppliers and forwarded to the TSI and the vessel.

It is the TSI responsibility to verify that the correct grades of oils and fluids are used on the vessels under her/his control and that any anomalies indicated in the routine analysis reports are investigated and any necessary remedial action taken.

The grades must be checked with respect to machinery makers recommendations, engine operating loads, fuel sulphur content, ambient conditions.

Particular attention must be paid to particle analysis reports where developing trends may indicate abnormal wear of machinery components or malfunction of purifiers or other cleaning equipment.
