PERTH, Australia — Woodside Energy has awarded decommissioning contracts for its subsea infrastructure at four oil and gas fields offshore Western Australia: Enfield, Griffin, Stybarrow and Echo Yodel.

Subject to regulatory approvals, the decommissioning campaign should start in the fourth quarter and will include decommissioning of the Nganhurra Riser Turret Mooring (RTM) on the Enfield Field, the Griffin RTM and the Stybarrow disconnectable turret mooring.

Contracts awarded cover the removal and disposal of riser and disconnectable turret moorings, umbilicals, flowlines and associated subsea infrastructure. Engineering groups involved include TechnipFMC, Heerema, McDermott, Fugro, DOF and McMahon, while Transocean will perform P&A of wells at Stybarrow.

Michal Abdullah, Woodside’s vice president of projects Australia, said, “We are partnering with a range of providers with specialist capabilities and experience to ensure safe and successful execution of one of the largest decommissioning campaigns undertaken offshore Western Australia. We are progressing well with our planning and remain on track to meet the regulatory requirements to complete the campaign.”

Stakeholder consultations continue to inform the development of environment plans for the campaign, some of which are with the regulator, NOPSEMA, for review.
