Findings (3)

R-PV-10Data plate missing or unreadableRecords / traceabilityS2 × L4 = 8Moderate

The vessel cannot be traced to its registered design data from markings on the equipment.

Action Recover the design registration from the plant register and fit a durable replacement plate carrying the registration number and MAWP.

Loss of design or inspection traceability · due 2026-07-27 · AS/NZS 3788 §4.4

R-PV-14Drain inoperable or condensate presentObservationS2 × L4 = 8Moderate

Condensate cannot be drained, which drives internal corrosion at the bottom of the shell.

Action Free or replace the drain and add a daily drain check to the operator round.

Structural failure under load · due 2026-06-27 · API 510 §6.4

R-PV-13Pressure gauge missing or unreadableObservationS2 × L3 = 6Moderate

Operating pressure cannot be read at the vessel.

Action Fit a gauge spanning at least 1.5 times MAWP and mark the normal operating range on the dial.

Uncontrolled release of stored pressure · due 2026-06-27 · AS/NZS 3788 §5.7
