Santos secures Atteris for Spartan contract

Santos has awarded Atteris a subsea front-end engineering design (FEED) contract for the Spartan gas field offshore Western Australia.

The engineering design work will include the subsea infrastructure connecting the subsea christmas tree to the John Brookes wellhead platform. The subsea system will consist of an umbilical, a flexible flowline, a flowline end termination structure and a rigid metrology spool.

Atteris general manager Dermot O’Brien said: “We are thrilled with this win and we are grateful for the trust and confidence that Santos has placed in us with yet another significant subsea engineering design scope.”

Spartan is in permit WA-33-R, 40km west of Varanus Island and 18km from the John Brookes wellhead platform.

In 2016, Quadrant Energy, which was subsequently acquired by Santos in 2018, discovered gas at its Spartan-1A well in the North West Shelf.

“The Spartan-1A well is located 15km south east of the John Brookes gas field, and according to exploration partner Santos, the well is a potential future tie-back into existing infrastructure located onshore,” Quadrant outlined in 2016.

Arteris provides engineering services in the following areas: subsea and pipelines, flow assurance, dynamic systems, asset and integrity management, operations and production/production readiness support, life extension assessments and decommissioning studies.
