Woodside Energy Global reported a notifiable incident (NTF11740) at the Pyrenees facility on 30 August 2022 involving a vacuum release line at the 3S cargo oil pump discovered during planned radiography inspections with wall thickness of 0.65mm, below the minimal allowable wall thickness. The equipment was isolated pending repairs. NOPSEMA escalated the dangerous occurrence to level 1 investigation on 31 August 2022. The immediate cause was identified as external corrosion and wall loss from galvanic corrosion. Subsequent inspections revealed nine cargo oil pump vacuum release spools were at or below minimal allowable wall thickness across multiple pumps (1S, 1P, 2P, and 3S positions), with thickness measurements ranging from 0.66mm to 2.64mm. Woodside submitted an initial report on 2 September 2022, reviewed by NOPSEMA on 8 September 2022.
