Woodside Energy Ltd reported a dangerous occurrence (NTF11832) at the Vincent offshore facility in Western Australia on 4 October 2022 involving a faulty oxygen sensor and non-operational alarm beacons in the pump room. The incident occurred during an internal vessel disconnection exercise and was notified to NOPSEMA on 25 October 2022, three weeks after the event. The oxygen detector failure was discovered during maintenance testing; the work order had not identified it as safety-critical equipment, preventing proper reporting. Additional beacon failures were identified during environmental and emergency response assessment inspections. NOPSEMA escalated the matter to level 1 investigation on 1 November 2022. Woodside initiated internal investigation under its standard Health, Safety and Environment Event Reporting procedure.
