Woodside Energy Global Pty Ltd reported a notifiable incident (NTF11880) at the Pyrenees offshore facility in Western Australia on 21 November 2022 involving failure of emergency lighting battery backup systems. Routine maintenance inspection discovered multiple emergency lights in accommodation and one at the disembarkation ladder failed to meet the required 60-minute backup power performance standard. The root cause was depleted batteries due to age. While failed batteries were replaced, no spare battery was available for the port side evacuation ladder emergency light, though alternative portable lights were noted as available. NOPSEMA classified this as a dangerous occurrence under occupational health and safety damage to safety-critical equipment and escalated it to level 1 inspection on 23 November 2022. The duty holder submitted an initial report on 23 November, one day ahead of the required 24 November deadline.
