Trend analysis helps identify gradual changes or abnormalities in oil properties, allowing maintenance teams to take proactive measures, such as adjusting maintenance practices, identifying potential equipment faults, or planning for equipment upgrades or replacements.

4. Oil Analysis Process

The oil analysis process typically involves the following steps:

Sample Collection

Representative oil samples are collected from the equipment using specialized sampling techniques and tools. It is important to follow proper sampling procedures to ensure accurate and reliable results.

Laboratory analysis

At the laboratory, trained technicians perform various tests and analyses on the oil sample to evaluate its properties and characteristics. The specific tests conducted may vary depending on the objectives of the analysis, but common tests include:

• Visually inspect the oil for colour, clarity, and the presence of contaminants like metal particles or water.
• Determining basic oil properties such as viscosity, acidity, and oxidation level.
• Particle counting to assess the level of contamination or wear debris in the oil.
• Spectroscopic analysis, such as elemental analysis (inductively coupled plasma-atomic emission spectroscopy) or infrared spectroscopy, to identify and quantify the presence of various elements or compounds.
• Ferrography or microscopic examination to study the morphology and composition of wear particles.
• Additional specialized tests may be performed based on specific requirements or known issues with the equipment.

Data interpretation and reporting

Once the analysis is complete, the laboratory generates a detailed report summarising the findings and providing recommendations. The report typically includes the test results, deviations from normal values, trend analysis, and suggestions for maintenance or corrective actions if needed. Some laboratories may also provide online portals or software tools to easily access results and trends.

Maintenance personnel or reliability engineers are responsible for the equipment review of the oil analysis report. They interpret the findings in the context of the equipment's operational conditions and determine appropriate actions. These actions may include changing the oil, further investigation or inspection, equipment maintenance or repairs, or adjustments to the lubrication program.

Trend analysis

Oil analysis is most effective when conducted regularly and tracked over time. By comparing the results of multiple samples taken at different intervals, trends can be identified, and potential issues can be detected early. Trend analysis helps in establishing baseline values, evaluating the effectiveness of maintenance actions, and predicting future performance or failures.

5. Integrating Oil Analysis into Waste Management Practices
