Woodside is submitting a revision of the North West Shelf (NWS) Project’s Angel Operations Environment Plan in accordance with the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009 (Cth). The Angel platform is located in Commonwealth waters about 125 km north-west of Karratha in Western Australia and has been operating since 2008. The facility consists of subsea hydrocarbon gathering systems, a riser platform and an export pipeline. This Environment Plan is being revised and resubmitted to integrate drilling, subsea installation, commissioning (drilling and tie-back) and production from the Lambert West reservoir (Lambert West tie-back) into the existing Angel production systems. The following activities are proposed to occur within Production Licences WA-16-L and WA-3-L and Pipeline Licences WA-31-PL and WA-14-PL:
• routine production and associated activities
• routine inspection, monitoring, maintenance and repair (IMMR) of the platform and associated subsea infrastructure
• well clean up and commissioning
• drill new well in the Lambert West field
• subsea infrastructure installation
• pre-commissioning and commissioning activities.
The Angel facility will operate 24 hours a day for the 5-year duration of this EP. The Lambert West drilling and tie-back activities are planned to occur in 2024, with contingency to occur in 2025.
Angel is an offshore not normally manned (NNM) production platform that produces dry gas and condensate. Gas and condensate is processed on the Angel platform then transported via an export pipeline to the North Rankin Complex, and then onshore to the Karratha Gas Plant (KGP) for processing. The Angel platform is marked on nautical maps surrounded by a 500 m exclusion zone to shipping.
