The Basker-Manta-Gummy (BMG) field is located in water depths of approximately 135 m to 265 m in Petroleum Retention Lease VIC/RL13, approximately 55 km south of Cape Conran in East Gippsland, Victoria in the eastern waters of Bass Strait.
 The BMG offshore assets consist of:
•          Basker-2, Basker-3, Basker-4, Basker-5, Basker-6 (ST-1), Basker-7 and Manta 2A wells (& associated subsea equipment), which are shut-in;
•          The Basker-A Manifold (BAM) and various minor associated subsea equipment
•          Interconnecting flexible flowlines, service lines and control umbilicals between the BAM and individual wellheads;
•          Static sections of the Manta-2A production flowline and Basker production and re-injection flowlines;
•          Basker-6 production flowline from the Basker-6 wellhead to the BAM and its associated control umbilical; and
•          Control umbilicals running between the BAM  and Manta-2A.
 Note that all mooring equipment, mid-water and surface equipment associated with the Floating Production Storage and Offloading (FPSO) facility  was removed in 2010.
 The scope of this Environment Plan covers the Non-Production Phase of the offshore facilities for a period of up to 5 years. As the wells are shut-in, and the flowlines cleaned and filled with inhibited water, operational activities are limited to vessel operations including visual inspection, maintenance and repair activities to maintain the integrity of the assets.
