On 3 October 2022, Woodside Energy Ltd's Vincent offshore facility in Western Australia experienced an unplanned emergency alarm when smoke was detected in the marine generation room. A technician preparing diesel generator #2 for restart inadvertently triggered the smoke detector through combustion products from engine blow-over operations. The facility implemented its emergency response plan, completing a full muster before returning to normal status. NOPSEMA classified this as a dangerous occurrence and escalated the incident to level 1 inspection on 4 October 2022. The immediate cause was identified as the technician's failure to recognize that blowing the engine on air could activate the adjacent smoke detector. Woodside submitted its incident report by the required deadline of 6 October 2022, which NOPSEMA reviewed on 12 October 2022. No environmental release occurred.
