Woodside Energy Ltd reported a notifiable incident (NTF11806) on 14 October 2022 involving defects in the produced water system aboard the CWLH OKHA FPSO, a floating production facility off Western Australia. During inspection, two minor weeps were identified in safety-critical pressure equipment: one on a valve body discharge valve and another upstream of a level control valve, both measuring 0% LEL. The incident was categorised as damage to safety-critical equipment and classified as a dangerous occurrence. NOPSEMA escalated the matter to level 1 investigation on 18 October 2022. Woodside engaged facility engineering to approve temporary repairs and commenced investigations into permanent repair strategies. No escalation to baseline risk was identified, and the immediate causes were to be determined through Woodside's internal investigation procedure.
