Activity Description

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 (Figure 1‐1). 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 licence WA‐19‐PL and WA‐20‐PL.
 
Commissioning and start‐up activities are planned to commence in Quarter 2 2015. Following start‐up, operations 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
associated vessel activities.
 
These activities are supported by vessels and remotely operated vehicles (ROVs) where required.
