Lub Oil Analysis

Lub Oil Analysis

Protecting your equipment with oil analysis.

Lube oil analysis is the most well-established of all condition monitoring methods. The information contained in used lube oil gives very early warnings regarding the health of the equipment it is in contact with.

While the standard approach to the analysis of used oil has been to concentrate on large systems such as main propulsion engines and hydraulic circuits with a view to understand if the oil is fit for re-use, at SeaTec we have a different perspective - we look at oils from all systems with a view to understand the state of the equipment it is in contact with.  Although the amount of oil in circulation in a small system may be a litre or two and can easily be replaced, it is the condition of the equipment we are estimating and not so much the re-usability of the oil.

The routine tests on lube oil samples include viscosity@40°C, Viscosity@100°C, water, soot, acid number, base number, ISO codes, PQ index & spectrometric analysis. We are also specialised in ferrographic and microscopic analysis. The test suites are being selected according to the equipment and the type of the lubricant in use. At SeaTec we have combined the strength of one of the largest fluid analysis laboratories in the world with the expertise of experienced marine engineers which helps you the extract the most value out of your lube oil analysis. Our report comments individually on the condition of the equipment as well as the condition of the oil providing three indices of health - Satisfactory, Alert and Critical.   Every test result is manually checked and scrutinised and the systems reliability enjoyed by our clients bear testimony to the usefulness of our service.

Cylinder scrape down analysis

This is performed on low speed marine two stroke engines to assess the condition of the cylinder lubricants. The residue oil taken from the piston underside and the system oil is analysed and can give indication/insights on wear, remaining BN, combustion quality and contaminants such as water or system oil.  These tests also help you in optimising cylinder oil feed rate and thereby providing considerable savings.
