The contract, which is believe to worth in excess of US$50 million, follows McDermott’s recent completion of the Campbell decommissioning project for Santos in Australia.

The Harriet Alpha platform, part of the Harriet Joint Venture (HJV) assets, is one of the largest facilities set for decommissioning in the region.

McDermott’s scope of work includes engineering, procurement, and fabrication of specialised equipment, alongside the removal and transportation of the platform structure to an onshore facility for dismantling and disposal.

Additional tasks include the removal, transportation, and disposal of a flare tower, an exploration well, and a subsea development system comprising two subsea template wells.

“This is our largest decommissioning project to date, reflecting our continued commitment to delivering bespoke solutions for the timely, safe, and environmentally responsible removal of infrastructure at the end of its operational life cycle,” said Mahesh Swaminathan, McDermott’s Senior Vice President, Subsea and Floating Facilities.

“McDermott’s growing decommissioning portfolio in Australia also underscores the commitment we share to continue supporting circularity efforts in a lower carbon economy.”

Project management and engineering for the Harriet Alpha decommissioning will be carried out by McDermott’s team in Perth, Australia, with additional support from teams in Batam, Indonesia, and Kuala Lumpur, Malaysia.
