Decommissioning the Northern Endeavour

The Australian Government is decommissioning the Northern Endeavour facility and remediating the Laminaria-Corallina oil fields.

The Australian Government determined that decommissioning is the most effective way to protect the environment from future potential risks.

Decommissioning follows liquidation of the Northern Endeavour’s former owner, the Northern Oil and Gas Australia (NOGA) group of companies.

Costs are being recovered from the oil and gas industry through the Laminaria and Corallina Decommissioning Cost Recovery Levy. The levy ensures taxpayers are not left to pay for decommissioning and remediation.

Decommissioning and remediation phases and activities

The government is eager to complete the work as quickly as possible while ensuring workers are safe and the environment is protected.

The program is being delivered across 3 phases. Each requires detailed planning and environmental approvals.

  • Phase 1: Decommissioning and disconnecting the Northern Endeavour from subsea equipment and temporarily suspending the wells – in progress

    Petrofac Facilities Management Limited is the registered operator and the lead contractor managing phase 1 decommissioning activities.

  • Phase 2: Permanently plugging and abandoning wells


  • Phase 3: Removing subsea infrastructure and remediating the Laminaria and Corallina fields


About the facility

The Northern Endeavour is a 274m long floating production storage and offtake facility. It is permanently moored between the Laminaria and Corallina oil fields. Its location is approximately 550 km northwest of Darwin in the Timor Sea.
