PV-014 is a 5000 l process-buffer pressure vessel manufactured by Kesselbau Arens, commissioned
in 2019 and installed on the Hall 2 process line at the Aldervik yard.[^s1]

PV-014 passed its annual pressure-vessel inspection on 11 June 2026.[^s2] Wall thickness at
nozzle N2 measured 6.2 mm, down from 6.8 mm at the 2023 inspection.[^s3] The vessel passed its
pressure test at 14 bar test pressure, and surface corrosion at nozzle N2 was ground back and
recoated.[^s4][^s5] Following the inspection, the inspection interval was shortened from 24 to 12
months, and the vessel was placed under observation.[^s6]

Werkhof service technician L. Petersen recommends budgeting for a replacement vessel in 2028
rather than re-nozzling the current one, on the view that the wall-thickness trend at nozzle N2
will not support another re-coating cycle.[^s7]

## Change Log

- 2023: wall thickness at nozzle N2 measured 6.8 mm.[^s3]
- 2026-06-11: wall thickness at nozzle N2 measured 6.2 mm; the inspection interval was shortened
  from 24 to 12 months and the vessel placed under observation.[^s3][^s6]

## Open Points

### Wall-thickness re-test
id: op-wall-thickness-retest
- 2026-06-17: ultrasonic re-test of PV-014's wall thickness scheduled for December 2026.[^s8]
