NOPSEMA received a notifiable incident report from Woodside Energy Ltd regarding a failure of the fire suppression system in the galley accommodation area of the Vincent offshore facility on 12 September 2022. The incident involved a faulty O-ring in the CO2 firing circuit that prevented the firing pin from activating during routine maintenance function testing, constituting non-compliance with Performance Standard F19. The system was repaired and restored to working order. The incident was categorized as a dangerous occurrence involving damage to safety-critical equipment and escalated to level 1 inspection on 13 September 2022. Woodside submitted an initial investigation report on 14 September 2022, noting the perished O-ring as the immediate cause and referencing their internal event reporting and investigation procedures. Despite the system having passed a six-monthly inspection in March 2022, the defect was not detected until the September function test.
