Beach Energy Limited’s proposal to undertake subsea installation and commissioning activities in the Otway Basin in Victoria has been approved by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).
The proposed activities are to occur at the recently drilled Thylacine North-1, Thylacine North-2, Thylacine West-1 and Thylacine West-2 production wells associated with the Otway Offshore Phase 5 Development within petroleum production licence T/L2 and T/L4. The wells will be tied in to the existing Thylacine-A gas production platform.
The activity area is located within the Otway Basin in Commonwealth waters, approximately 65 kilometres southwest of the Victorian coastline at its closest point (Cape Otway) and 70 kilometres south of Port Campbell. The Apollo Australian Marine Park (AMP) is located 50 kilometres east of the activity area. Water depth at the proposed installation location is approximately 100 metres.
The scope of works includes the installation of rigid spools, manifolds, concrete mattresses, electrohydraulic umbilicals, production flowlines and electrical and hydraulic flying leads.
The activity will be undertaken using a construction support vessel. Commissioning of the newly installed equipment will involve testing of the spools, umbilicals and flying leads using monoethylene glycol and water.
The installation and commissioning activity is planned to occur between early this year and will take up to 60 days to complete, depending on sea state conditions and technical matters.
