Australia’s Department of Industry, Science and Resources has issued a request for tender (RFT) for a lead contractor to deliver Phase 3a of the Northern Endeavour Decommissioning Program.

Published on 14 August 2026, the tender covers the recovery, transport and offloading of subsea infrastructure from the Laminaria and Corallina oil fields to a nominated Australian port. Submissions close on 23 October 2026.

The work will be carried out in two stages.

The first stage will focus on planning and preparation for offshore operations. This includes project, engineering and logistics planning, procurement and subcontractor management, project planning, regulatory approvals, permits and other required authorisations.

The contractor will also be required to submit a Stage Gate Review Pack for approval. Stage 2 can begin once the department approves the pack.

The second stage will involve removing subsea equipment from the Laminaria and Corallina seabed, transporting the recovered infrastructure to a nominated Australian port and offloading it for transfer to the Phase 3b contractor.

The successful contractor will also undertake the project management, engineering, logistics and procurement activities required to complete the work.

The programme requires the successful contractor to meet several priorities, including:

• achieving outstanding safety, health and environmental performance;
• delivering quality outcomes through good industry practice and standards;
• effectively managing risk and change;
• complying with regulatory requirements and timeframes;
• delivering a technically compliant solution that provides value for money; and
• aligning delivery with environmental, social and governance expectations.
