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

Drain inoperable or condensate presentR-PV-14ObservationS2 × L4 = 8

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

Pressure gauge missing or unreadableR-PV-13ObservationS2 × L3 = 6

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
