# Make equipment history useful without bypassing safeguards.

Consider pumps, valves, vessels and exchangers with their duty, work history and authorised mechanical-integrity procedures.

## What connects an equipment trend to a competent integrity review?

Asset identity, operating duty, inspection history, instrument quality and a clear engineering question—without substituting analytics for prescribed inspection, testing or protective functions.

This guide considers one operating question in chemical & petrochemical processing, connecting equipment observations to the work, the available context and the people responsible for the next decision.

## Know which equipment is within scope.

Pressure vessels, storage tanks, piping, relief and vent systems, emergency shutdown functions, monitoring devices and pumps may have specific integrity requirements at covered facilities.

OSHA’s process safety management standard describes mechanical integrity obligations for applicable equipment. The site must identify which obligations apply; a general website guide is not an inspection programme.

## Compare equipment conditions under meaningful duty.

Pump vibration, motor current, valve position and exchanger temperatures can vary with process load, medium and control mode. State those conditions when comparing trends.

Hypothetical example: a heat exchanger outlet temperature changes after a product change. The team checks feed conditions and cleaning history rather than immediately assigning fouling as the cause.


## Bring maintenance and inspection into the same review.

The timing, scope and verification of work affect what a later trend can support. Keep prescribed inspections, test results and qualified engineering conclusions distinguishable from background telemetry.

A useful operational record can point reviewers to the work performed and known limitations without altering the source of the authorised integrity decision.


## Create a reliable next step, not an automatic command.

A review can end with an observation needing verification, a supported explanation or a finding requiring another process. It should document owner and required evidence.

VIEOX discussions can begin with one asset family whose records are currently difficult to connect, under the site’s rules for sensitive information.


## Practical starting points

- Select equipment and applicable inspection scope.
- Check operating duty and measurement quality.
- Read maintenance and test events against the trend.
- Retain the qualified approval and safety boundaries.

## Questions, answered

### Can vibration data replace mechanical-integrity inspection?

No. Where inspection and testing requirements apply, those remain necessary; trends may support additional questions.

### Does an apparent threshold exceedance allow automatic shutdown commands?

It does not create authority to command equipment. Control and protective decisions follow the site’s engineered procedures.
