Findings (4)

R-PV-03Relief discharge path obstructedNon-conformingS4 × L3 = 12High

The relief device cannot discharge freely to a safe location.

Action Clear the discharge path and re-route it away from any walkway or work position.

Uncontrolled release of stored pressure · due 2025-11-04 · AS/NZS 3788 §5.6

R-PV-06Heavy external corrosion or section lossNon-conformingphotographic evidenceS4 × L3 = 12High

External corrosion has progressed to the point where remaining wall thickness cannot be assumed.

Action Arrange ultrasonic thickness testing at the affected areas and compare against the minimum design thickness before the next fill.

Structural failure under load · due 2025-11-11 · API 510 §6.3 · evidence VC-CORR-HEAVY

R-PV-10Data plate missing or unreadableRecords / traceabilityphotographic evidenceS2 × 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 2025-12-27 · AS/NZS 3788 §4.4 · evidence VC-NAMEPLATE

R-PV-15Working space around the vessel restrictedImprovement opportunityphotographic evidenceS2 × L3 = 6Moderate

There is not enough clear space to inspect, isolate or escape from the vessel position.

Action Clear and mark the working space around the vessel.

Access, egress and emergency response impaired · due 2025-12-27 · ISO 12100 §6.2.7 · evidence VC-OBSTRUCTED-ACCESS

Photographic record

Site photograph taken at assessment

An illustrated vertical blue air receiver on a base frame, with a top-mounted PSV and gauge, a side pressure gauge, a rust-covered plate, and a cardboard box and green container beside it on the right.

Heavy corrosion or section loss, Extensive orange-brown rust patches with an irregular, flaking appearance cover most of the lower shell course and extend over the base frame and legs, well over a quarter of the visible lower surface.
Light surface corrosion or coating breakdown, Rust patches extend beyond the plate onto the surrounding blue coating on the upper shell course.
Nameplate missing or unreadable, The plate is largely covered by rust. Only faint lines are visible and no text can be read.
Working space obstructed, A cardboard box on a pallet and a green container are stored close beside the vessel, near the side gauge area.
