Engineering services provider Atteris announced on Jun 23 that Australian energy company Santos has awarded it the subsea, umbilical, risers and flowline pre-FEED for the Dorado project field development. The Dorado field is located within the Bedout Sub-basin, some 150 km north of Port Hedland, Western Australia, in a water depth of approximately 95 metres. The Dorado project is a joint venture between Santos (operator) and Australian exploration company Carnarvon Petroleum.
The engineering design work will include the subsea infrastructure connecting the well head platform to the disconnectable turret mooring of a floating, production, storage and offloading vessel. The subsea system will consist of four flexible risers and associated flowlines including two production lines, one gas injection line and one dynamic and static power and controls umbilical. Atteris will perform the configuration design of the dynamic riser system, the stability assessment of the flowlines and static umbilical, and the field layout definition.
Atteris’ Dynamic Systems Business Stream, led by Principal Engineer Céline Lanoëlle, will deliver the scope working closely with the Santos team in Perth, Western Australia. Céline: “My team of engineers and I are thrilled with this win. We have worked hard to develop this capability and we are now leaving our positive marks in the industry. We are grateful for the trust and confidence that Santos has placed in us with this contract.”
Atteris, with offices in Perth Australia and Houston USA, 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.
