Under the engineering, procurement and construction (EPC) contract, Woodside will supply a subsea production system, as well as a dual multiphase boosting system for the project.
The contract will include six horizontal SpoolTree subsea trees, six horizontal trees for the water injection system.
OneSubsea will also supply six multiphase metres, a dual pump station with high-voltage motors, umbilical, topside, subsea controls and distribution, intervention and workover control systems.
A landing string and installation and commissioning services are also included in the contract.
The development follows approval received by Woodside Energy and joint venture partner Mitsui E&P for the Greater Enfield project development.
The project is located 60km off Exmouth in Western Australia within Commonwealth waters.
It will develop the Laverda Canyon, Norton over Laverda (WA-59-L) and Cimatti (WA-28-L) oil accumulations.
Reserves are planned to be produced through a 31km subsea tie-back to the Ngujima-Yin floating production storage and offloading facility, located over the Vincent oilfield.
As part of Greater Enfield, six subsea production wells and six water injection wells will be developed and production will be supported by subsea multiphase booster pumps in the Laverda area and gas lift in the Cimatti area.
Woodside reserves are expected to increase by 41 million boe in conjunction with approval of the project for development.
The project is a joint venture between Woodside Energy (operator, 60%) and Mitsui E&P Australia (40%).
