Hydro-pneumatic accumulator 104
Pressure vessel / air receiver · Northgate Works · Line 4 · inspector J. Barros
Identification and records
Establish what the vessel is and that its design and inspection history can be evidenced.
Nameplate and general arrangement
9 cues in forceOne frame showing the vessel and, if you can, the data plate.
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.
Illustration of a vertical air receiver; clear overall, but the nameplate text is obscured by rust and the base area is partly hidden by corrosion patches. A blurred yellow object in the left foreground is out of focus.
Lower third of the shell and base/support area, centre-left of frame. 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.
Accepting this evaluatesR-PV-06R-PV-07
Upper shell around the plate, upper-left of vessel. Rust patches extend beyond the plate onto the surrounding blue coating on the upper shell course.
No enabled rule consumes this cue, so accepting it records evidence only.
Rectangular plate on the upper shell, left of centre. The plate is largely covered by rust. Only faint lines are visible and no text can be read.
Accepting this evaluatesR-PV-10
Right of the vessel, floor level. A cardboard box on a pallet and a green container are stored close beside the vessel, near the side gauge area.
Accepting this evaluatesR-PV-15
Top of vessel, PSV labelled with a horizontal discharge pipe to the right. The PSV has no visible cap or wire. It discharges horizontally, and its termination direction relative to people or surfaces cannot be confirmed. Whether an isolation valve sits beneath it cannot be determined.
Accepting this evaluatesR-PV-03
Floor beneath the vessel base. A dark oval patch is visible on the floor below the vessel. It may be a shadow or pooling; no wet trail from a fitting is visible.
Accepting this evaluatesR-PV-16
Floor around the vessel and to the right. Stored box and container are near the asset, and a dark patch sits under the vessel. No clear debris, rags or spills are identifiable.
No enabled rule consumes this cue, so accepting it records evidence only.
- Blurred yellow and black striped post (possibly a bollard or protection post) in the left foreground.
- Heavy corrosion at the base frame and legs may affect support integrity; section loss cannot be quantified from the image.
- Readings on either gauge could not be read at this resolution.
Recorded on the report as notes. No cue, so no rule consumes them.
2 cues checked and not seen
- Pressure gauge missing, broken or unreadable, Two gauges are fitted. Both faces are intact with visible scale marks and pointers, and no cracks or fogging are apparent.
- Impact damage or deformation, No dents or bent members are visible, although the heavily rusted base limits the view.
