The Otway Offshore Development produces raw gas and condensate from the Geographe and Thylacine fields, which are transported via pipeline to an onshore gas plant near Port Campbell, Victoria. The current approved field development plan has an end of field life of 2026.
Offshore infrastructure includes subsea wells, the unmanned Thylacine-A production platform, and the offshore pipeline system from the platform to the shore crossing to the west of Port Campbell.
An umbilical between Thylacine and Geographe transports MEG, chemicals (methanol, scale inhibitor) and hydraulic fluid to Geographe in addition to power and controls.
The Thylacine field is located approximately 70km offshore from Port Campbell, Victoria, in approximately 100m of water. The Geographe reservoir is located approximately 55km offshore in 85m of water.
