Environment plan title: Bayu-Undan to Darwin Gas Export Pipeline Environment Plan (Document No. 7710-057-EIS-0001, Revision 6, dated 24 June 2024)

Description/stage of activity:

Operations phase:

• transporting dry natural gas from the BU Field to Darwin LNG Plant
• line-packing the pipeline up to maximum operating pressure (during periods of maintenance and towards the end of production at the BU Facility)
• back-feed of gas from the pipeline to BU CPP for power generation (during maintenance and testing and once production ceases from the BU Field).

Preservation phase (begins when the gas is no longer being used for power generation at BU CPP):

• the pipeline remains filled with reservoir gas.

Pipeline inspection, maintenance, monitoring and repair.

• Pipeline IMMR activities, including vessel-related activities will continue through all the above phases.
