Activity Description
Beach Energy (Operations) Limited (‘Beach’) proposes to undertake subsea installation and commissioning activities (the activity) associated with the Otway Offshore Phase 4 Development within petroleum production licence VIC/L23.

The activity area is located within the Otway Basin in Commonwealth waters, approximately 45 km southwest of the Victoria coastline at its closest point. The closest major town is Port Campbell, located approximately 54 km northeast of the north-eastern boundary of the activity area. The Apollo Australian Marine Park (AMP) is located 47 km east of the activity area. Water depth at the proposed installation location is approximately 83 m.

The scope of this EP includes the installation of tie-in spools, electrical flying leads (EFLs) and hydraulic flying leads (HFLs) to connect new production wells (Geographe-4 and Geographe-5) to the existing gathering systems. The activity will be undertaken using a construction support vessel (CSV).
The activities assessed under this EP include:
• Removal and recovery of the Geographe-3 rigid spool;
• Installation of two rigid spools between the existing manifold and the new Geographe-4 and Geographe-5 production wells;
• Installation of seven EFLs and two HFLs, including on-bottom stabilisation; and
• Commissioning program, including production spool leak testing and electrical and hydraulic function testing.

The proposed activity will be undertaken over a period of up to 30 days in the four-month window of the start of August 2021 to the end of October 2021 (with a contingency for November in case of project delays), with the exact timing for commencement and completion being dependent upon vessel availability, granting of EP approval and sea state conditions.
