Mr Gerard Ransom
Woodside Energy Ltd (Woodside) is operator of the Okha Floating Production Storage and Offloading (FPSO) facility, which is located offshore approximately 135 km North West of Karratha, Western Australia.
The Okha FPSO consists of subsea wells, associated topside processing and subsea infrastructure and a single Gas Export Line (GEL). The Okha FPSO and associated infrastructure is located in Commonwealth waters on the North West Shelf (NWS) of Western Australia in Production Licence Areas WA-9-L, WA-11-L and WA-16-L. The FPSO is situated in 80 m of water over the central area of the Wanaea field.
The export pipeline is covered by Pipeline Licence WA-4-PL, and depths along this pipeline range from 80 m at its Eastern end (Okha FPSO) to 125 m at its Western end (NRC which is approximately 32 km East of the Okha FPSO). Oil from the Okha FPSO is dispatched to trading tankers, whilst gas produced is exported onshore for processing.
The closest nearshore sensitive habitats to the Okha FPSO are the Glomar Shoals (33 km North East), Montebello Commonwealth Marine Reserve (72 km South West), Rankin Bank (86 km West), and the Dampier Commonwealth Marine Reserve (88 km South East).
The Okha FPSO commenced production in September 2011 as part of the Cossack Wanaea Lambert Hermes (CWLH) re-development project. Prior to Okha, the CWLH oil fields were produced through the Cossack Pioneer FPSO which commenced production in 1995. The Okha FPSO operates 24 hours per day, 365 days per year. Supporting operations, such as maintenance activities, take place as required.
