Can pressure vessel and boiler statutory examination move from a fixed interval to a condition-based check?

Statutory: the interval is set by law or a statutory code and stays on the calendar. Examination intervals are set by the written scheme under the Pressure Systems Safety Regulations in the UK, AS/NZS 3788 in-service inspection in Australia, and state boiler and pressure vessel laws (NBIC) in the US.

What condition would trigger pressure vessel and boiler statutory examination instead of the calendar?

Partly. Wall thickness by ultrasonic testing and safety valve lift can be trended, and pressure and temperature are already monitored; the examination under the written scheme stays on its statutory interval.

What reading proves pressure vessel and boiler statutory examination was done?

Wall thickness at marked points, safety valve set pressure and lift, pressure and temperature history, weld or corrosion findings. Observed by: Competent person examination under the written scheme; ultrasonic thickness gauge for the trend.

What evidence does pressure vessel and boiler statutory examination produce for an ISO 55001 or ISO 45001 audit?

Examination report per vessel with the next examination date, and the thickness readings by location

Pressure vessel and boiler statutory examination

Corrosion is a rate, and a thickness trend tells you the rate. The examination interval is still the law, but the trend tells the competent person where to look.

Condition that replaces the interval: Partly. Wall thickness by ultrasonic testing and safety valve lift can be trended, and pressure and temperature are already monitored; the examination under the written scheme stays on its statutory interval.
Reading that proves it: Wall thickness at marked points, safety valve set pressure and lift, pressure and temperature history, weld or corrosion findings
Why the interval stays: Examination intervals are set by the written scheme under the Pressure Systems Safety Regulations in the UK, AS/NZS 3788 in-service inspection in Australia, and state boiler and pressure vessel laws (NBIC) in the US.
Evidence an auditor accepts: Examination report per vessel with the next examination date, and the thickness readings by location
First move: Mark the thickness measurement points on the vessel so every reading is at the same spot; a trend from moving points is noise.
