Woodside Energy Ltd notified NOPSEMA of a dangerous occurrence at the Vincent facility on 18 July 2022 involving failure of a process control module (PCM) during shunt trip testing. The electrical failure occurred when device 64-XS-4055 failed to trip non-Ex loads in the production control container, activating isolations to that section of the process. The root cause was identified as incorrect configuration of the trip circuit. The incident resulted in no injuries or environmental releases. Woodside immediately restored and verified the functionality of the failed device and initiated an internal investigation under its health, safety and environment event procedure. NOPSEMA escalated the notification to level 1 inspection on 19 July 2022, categorizing it as damage to safety-critical equipment.
