Site-owned condition monitoring capability

The objective

Trusted information, timely action

Oil analysis adds value when sample quality, test selection, interpretation and response operate as one system.

A condition-monitoring program, not simply laboratory reporting.

The program should reveal lubricant degradation, contamination, wear and developing defects early enough to enable the right maintenance response.

Fluid health

Verify viscosity, additive condition, oxidation and contamination.

Machine condition

Detect wear, ingress and developing defects.

Decision quality

Connect results to practical, agreed maintenance actions.

Where oil analysis delivers value

Prioritise systems where condition data gives useful lead time

Prioritise systems where lubricant condition or wear information provides useful lead time for a decision.

Gearboxes & drives

Wear, contamination and lubricant condition in process and mobile equipment.

Hydraulic systems

Particle contamination, water ingress, fluid condition and component wear.

Engines

Oil condition, soot, fuel dilution, coolant ingress and wear trends.

Compressors & turbines

Lubricant health and early evidence of machine or system distress.

Controlled workflow

Sample, assess, act, learn

The process must maintain sample integrity and link every exception to a managed response.

  1. 1

    Define

    Asset, compartment, lubricant, failure modes, decision lead time.

  2. 2

    Sample

    Use the correct live-zone location, method, bottle and label.

  3. 3

    Test

    Select fit-for-purpose tests and establish comparable history.

  4. 4

    Assess

    Trend data against limits, duty, history and other condition evidence.

  5. 5

    Respond

    Inspect, re-sample, test further, plan work or escalate.

  6. 6

    Improve

    Verify findings, update strategy and retain program learning.

Sampling quality

Sampling quality is the foundation

A laboratory result cannot compensate for an unrepresentative, contaminated or poorly identified sample.

Representative sampling controls

  • Sample from a repeatable, representative point, preferably in a live, flowing zone
  • Standardise sample points, ports, hardware, bottles, flush volumes and labelling
  • Capture operating context: fluid, compartment, hours, top-ups, recent work and abnormal events
  • Avoid cross-contamination, dirty containers and inconsistent collection methods
  • Use procedures that can be followed reliably by site personnel

Program maturity

Build a site-owned program over time

Where is your oil analysis program in the maturity model below?

Level 1

Reactive reporting

Samples are collected and laboratory alarms are relied on; internal ownership is limited.

Focus the improvement plan on ownership, controls, decision rules and verified learning.

Level 2

Controlled program

Sampling points, hardware and procedures are standardised to improve confidence and repeatability.

Level 3

Integrated decisions

Site-owned targets and trends are linked to maintenance strategy and other condition evidence.

Level 4

Continuous improvement

Information drives RCFA, defect elimination, lifecycle decisions and verified improvement.

Alarm limits

Meaningful limits must lead to a decision

Set limits only after the sampling method, asset context, failure modes and available decision time are understood.

Set practical alarm limits

  • Confirm fluid, compartment, duty cycle, known failure modes and required lead time
  • Use baseline trends, OEM guidance, laboratory expertise and site history
  • Define an agreed response for each condition: inspect, re-sample, test further, plan work or escalate
  • Review alarm effectiveness against field findings and actual defect outcomes
  • Adjust limits when evidence shows that they are not supporting timely, appropriate decisions

Integration

Integrate oil analysis with the maintenance strategy

Oil analysis is strongest when it is evaluated with operating context and complementary condition evidence.

Use condition evidence together

  • Link sample results to asset criticality, functional failure modes and planned maintenance strategy
  • Compare exceptions with vibration, bearing condition, process data, inspections and operating history
  • Use recurring findings as inputs to RCFA, defect elimination and design / lifecycle decisions
  • Ensure work orders include the condition evidence, decision rationale and required verification
  • Confirm the condition has changed after corrective action, not merely that the task was closed

Mobilisation checklist

Program mobilisation checklist

Set up the operating controls before relying on results to direct maintenance work.

  • Asset register

    Asset, compartment, lubricant, criticality and sampling frequency.

  • Test slate

    Tests matched to lubricant, failure modes, operating context and decision needs.

  • Data workflow

    Laboratory interface, trend review, exception ownership and work-management linkage.

  • Sampling plan

    Sample points, access requirements, procedure, hardware and labelling.

  • Limits and actions

    Baseline, alarm levels, escalation triggers, roles and response pathways.

  • Assurance plan

    Competency, audit, sample-quality checks and recurring program review.

Turn oil data into actionable reliability insight

The right sample, test, interpretation and action must work together.

AMREA supports the controls, capability and continuous-improvement pathway required for dependable oil analysis decisions.
