Award of the Dorado FPSO FEED contract
Santos today announced the award of the FEED contract for the floating production, storage and offloading (FPSO) facility for the Dorado project, in the Bedout sub-basin, off Western Australia, to Altera Infrastructure (Altera).
The FPSO contract is the most important of the project, comprising the engineering, procurement, construction, installation, commissioning and testing of the facility.
Dorado is an integrated oil and gas project that is expected to be developed in two phases. The initial development involves the production of oil and condensate via a wellhead platform (WHP) and an FPSO. The gas will be reinjected in the initial phase to improve oil and condensate recovery, followed by a planned future gas production phase to backfill the domestic gas infrastructure in Santos, WA.
Dorado is a very low CO2 reservoir with around 1.5% CO2 and gas re-injection in the initial phase, making it one of the lowest emission intensity oil projects in the region.
In June, the project entered the Front-End Engineering and Design (FEED) phase, which involves a lot of work, including the awarding of contracts for FPSO and WHP. The FPSO contract will begin with full definition engineering by Altera to confirm the technical requirements for the FPSO and the associated disconnectable mooring system.
Santos Managing Director and CEO Kevin Gallagher said, “This contract is a milestone for the project and Altera brings extensive FPSO design and operation expertise to the development.
“The design of the FPSO will allow the integrated development of liquid and gas resources and will retain sufficient flexibility to support future exploration successes nearby. A contract for the design, supply and installation of the WHP will be awarded shortly.
Chris Brett, President of Altera Infrastructure Production, said: “We thank Santos for placing their trust in Altera and look forward to applying our 30 years of FPSO expertise and experience during FEED to provide a design for FPSO that meets the needs of Dorado development while delivering the latest emission reduction solutions in line with our vision to lead the industry towards a sustainable future.
The project has a federally approved Australian Industry Participation Plan, ensuring full, fair and reasonable opportunities for Australian industry to compete for the job. This is accessible through the Industry Capability Network website.
Santos owns an 80% stake in the Dorado project and is the operator. The remaining stake is held by Carnarvon Petroleum.
