Woodside Energy Ltd notified NOPSEMA of a dangerous occurrence on 17 August 2022 involving the CWLH OKHA FPSO in Western Australian waters. The lift gas compressor #1 emergency anti-surge station had one of two inputs non-functional due to an incorrect pressure transmitter reading, breaching performance standard 3.2, though all other safety systems remained operational and a secondary flow transmitter was still functional. The incident was escalated to level 1 investigation by NOPSEMA on 18 August 2022. Woodside's initial report, received 18 August and reviewed 20 August, indicated the deviation was discovered during normal operations via a control room alarm. The incident was classified as damage to safety-critical equipment and investigated under Woodside's Health, Safety and Environment Event Reporting procedure.
