About the Northern Endeavour

The Northern Endeavour is a 274 m long floating production, storage and offloading (FPSO) facility. 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 now owns the Northern Endeavour FPSO. As a result, the Australian Government 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 is progressing well. With the help of our lead contractor for phase 1, Petrofac, the FPSO has been disconnected and towed to Singapore. While in Singapore, the vessel will undergo further work to remove protrusions and strengthen and repaint the hull for its journey to Denmark for recycling.

Some important milestones

Future milestones

  • 2025 and beyond

    • Tow the FPSO to MARS’ ship recycling facility in Frederikshavn, Denmark for recycling.
    • Approach the market to deliver phase 3 of the program.
    • Get environmental and regulatory approval to remove the subsea infrastructure.
    • Remove subsea infrastructure and transport it to shore for reuse or recycling. This includes flowlines, chains and mooring infrastructure.
    • Plug and abandon 9 oil wells and remove well infrastructure in the Corallina and Laminaria oil fields to protect the environment. 
    • Remove subsea infrastructure from the oil fields.
    • Remediate the oil fields.
