About the Northern Endeavour

The Northern Endeavour is a 274 m long floating production, storage and offloading (FPSO) facility which we have disconnected and removed. It was permanently moored between the Laminaria and Corallina oil fields, about 550 km northwest of Darwin in the Timor Sea.

There are 9 oil wells on the sea floor associated with these oil fields.

Why we’re decommissioning the Northern Endeavour

Following liquidation of the former private owner, the Commonwealth took ownership of the Northern Endeavour FPSO. The Australian Government then announced plans to decommission, disconnect and dispose of the FPSO and remediate the Laminaria-Corallina oilfields.

Decommissioning is a normal and planned activity carried out in the offshore petroleum industry. It involves safely removing and recycling oil and gas production infrastructure. It also includes rehabilitating and removing risks to the surrounding marine environment.

How we’re decommissioning the Northern Endeavour

We aim to complete the decommissioning work efficiently and safely, ensuring value for money and protecting the surrounding environment. We’re managing the program across 3 phases.

  • Northern Endeavour work program

    We aim to complete decommissioning of the Northern Endeavour efficiently and safely, ensuring value for money and protecting the surrounding environment.
  • Offshore petroleum cost recovery levy

    The Offshore Petroleum Laminaria and Corallina Decommissioning Cost Recovery Levy (OP Levy) is a temporary levy on offshore petroleum production.

Our decommissioning progress

Phase 1 of the program is operationally complete and recycling of the FPSO is now underway following its safe delivery to the recycling facility.

Phase 2 of the program is in progress. This phase focuses on design and planning to permanently plug and abandon the 9 wells in the Laminaria and Corallina oil fields. We engaged Zenith Energy Australia Pty Ltd as the lead contractor. Zenith will initially plan the work, complete the engineering design and seek regulatory approval before starting offshore work.

Future milestones

  • 2026 and beyond

    • Work with Zenith Energy Australia Pty Ltd, the phase 2 lead contractor, to plan and design the work to plug and abandon 9 wells.
    • Evaluate the tenders to deliver phase 3a of the program to remove the subsea infrastructure in the Corallina and Laminaria oil fields and transport it to shore for recycling or disposal.
    • Approach the market to deliver phase 3b of the program to manage the onshore recycling or recycling of the subsea infrastructure. This includes flowlines, chains and mooring infrastructure.
