Woodside Energy has completed the award of all major contracts for the decommissioning of subsea
infrastructure at the Enfield, Griffin, Stybarrow and Echo Yodel oil and gas fields offshore Western Australia.
The contracts cover the removal and disposal of riser and disconnectable turret moorings, umbilicals, flowlines and other subsea infrastructure.
Specialist contractors engaged to undertake activities during the subsea decommissioning campaign include TechnipFMC, Heerema, McDermott, Fugro, DOF and McMahon. A contract for the permanent plug and abandonment of wells in the Stybarrow field has also been awarded to Transocean.
Woodside said the finalisation of these contracts supports the commencement, subject to regulatory approvals, of the decommissioning campaign in the fourth quarter of 2023. The upcoming work will follow decommissioning activities that have been underway at the Enfield and Balnaves fields since the first quarter of 2022.
