System view

One system. Several signals. One coordinated decision.

A solution combines several observations into one condition decision. It starts with the asset and credible failure modes, then selects complementary methods so one ambiguous indicator is not allowed to drive the conclusion.

For stationary condition assessment solutions, that means beginning with steam-trap and valve performance, working in the context of steam systems, and preserving enough evidence to support exception list by asset.

Engineering boundary

A condition assessment supports maintenance decisions; it does not replace protective systems, code compliance, original-equipment-manufacturer limits, or an engineering study required by the site.

Condition record

What should support the system-level conclusion.

  • The asset, audience, or system boundary and the decision being supported
  • The relevant operating state, access conditions, source records, and known limitations
  • The observations or results related to compressed-air, gas, and vacuum leakage
  • The comparison, technical reasoning, confidence, priority, and alternative explanations
  • The owner, timing, verification method, and trigger for escalation or follow-up

Challenge the diagnosis

What reviewers should test before action.

  • Was the evidence collected under a representative and documented condition?
  • Does another indicator support—or conflict with—the first conclusion?
  • Could access, setup, data quality, environment, or operating state explain the result?
  • Is the proposed action proportionate to condition, consequence, and uncertainty?
  • What new evidence would confirm that the action worked?

Evidence architecture

How the signals are assembled into a defensible conclusion.

The value comes from the relationship between evidence—not the number of technologies used.

  1. 01

    Define the system function and expected operating state

    Primary focus: Steam-trap and valve performance. Expected record: Exception list by asset. Typical setting: Steam systems.

  2. 02

    Screen a route for exceptions

    Primary focus: Compressed-air, gas, and vacuum leakage. Expected record: Evidence and operating context. Typical setting: Compressed-air systems.

  3. 03

    Verify exceptions with a complementary method where appropriate

    Primary focus: Thermal transfer patterns. Expected record: Repair or confirmation priority. Typical setting: Valves and piping interfaces.

  4. 04

    Quantify priority, loss, or follow-up need

    Primary focus: Visible or audible integrity indicators. Expected record: Route and retest recommendations. Typical setting: Heat exchangers and tanks.

SYSTEM INSIGHT
Stationary-asset losses are often individually small but operationally significant when repeated across a plant.
