Description


The Macedon Operations involves production of gas from the Macedon gas field via four subsea wells and associated subsea field infrastructure, with transport of the gas to an onshore processing plant via a subsea pipeline. The Macedon gas field is situated within production licence WA-42-L located on the North West Shelf in Commonwealth waters ranging from 120 to 180 m depth, approximately 40 km north of Exmouth and 100 km west of Onslow.
 The field infrastructure is operated remotely from the onshore gas plant via umbilical and production does not involve any onsite activity. The wet gas pipeline and umbilical in Commonwealth waters are approximately 24 km in length, extending up to the State-Commonwealth waters boundary, where water depths are approximately 60 m (Figure 3-1).
 Operations includes periodic IMR activities undertaken to ensure the ongoing integrity of infrastructure and consisting of vessel based operations that may include Remotely Operated Vehicles (ROV), Autonomous Underwater Vehicles (AUV) and/or diving activities.
 The Macedon Operations was commissioned in 2013 and production is continuous with an expected operating life of 20 years. IMR activities are conducted on an ‘as required’ basis throughout the life of field.
