The Gorgon and Jansz Feed Gas Pipeline and Wells Operations (Commonwealth Waters) Environment Plan covers activities in Commonwealth Waters associated with the commissioning, start‐up and operation of the Gorgon and Jansz Feed Gas Pipeline and Wells (the petroleum activity). Activities occurring outside the Operational Area or in the State jurisdiction are not included in the Plan. The Jansz–Io gas fields are located within production licenses WA‐36‐L, WA‐39‐L and WA‐40‐L approximately 200 km off the north‐west coast of Western Australia in water depths of approximately 1,350 m. The Gorgon gas field is located within production Licences WA‐37‐L and WA‐38‐L, approximately 130 km off the north‐west coast of Western Australia, and 65 km north‐west of Barrow Island in water depths of approximately 200 m. The wells associated with the Plan are located in WA‐36‐L, WA‐37‐L, WA‐38‐L and WA‐39‐L. The pipelines are located in Commonwealth Waters within pipeline licences WA‐19‐PL and WA‐20‐PL. The initial field development comprised of wells and subsea infrastructure, including the Feed Gas Pipeline, associated with the Gorgon Foundation Project, which was commissioned in 2015. This field development is being supplemented by Gorgon Stage 2 (GS2), which comprises additional wells and subsea infrastructure within the Gorgon and Jansz-Io gas fields. GS2 was part of the original field development plans for the Gorgon Gas Development. Commissioning and start‐up activities associated with GS2 are expected to commence in the first half of 2022. Operations of the Gorgon Gas Development are expected to continue for the nominal operational design life of 50 years. Inspection, maintenance and repair activities may occur at any time during commissioning, start‐up and operation. The timing of activities is indicative, and subject to potential delays caused by weather events, vessel availability and other unforeseen factors. The scope of the Plan covers petroleum activities associated with the commissioning, start‐up, and operation of the Gorgon and Jansz Pipeline and Wells in Commonwealth Waters. The petroleum activities addressed in the Plan include: commissioning and start‐up operations inspections, maintenance and repair (IMR) activities, and field support activities including support vessel activities and helicopter transfer. |
