Integrated engineering firm Fyfe has been awarded an engineering, procurement and construction contract for Santos’ Bayu Undan carbon capture and storage project in the Timor Sea.

The Bayu-Undan gas field will store up to 10 million tonnes of carbon dioxide per annum and will be needed to take CO2 from Santos' future Barossa project, whose fields average 12% CO2.

The project will require additions and modifications to the DLNG facility, which is proposed as the foundation for a CO2 processing hub, as well as the repurposing of the Bayu-Undan to Darwin Gas Export Pipeline, the offshore processing facility and facility wells for re-injection of processed CO2.

Fyfe was awarded the contract for brownfield construction and detailed design of tie-in of the onshore Darwin LNG project. The contract value was not made public.

The engineering company will consider the main process, utilities, and CO2 export piping.

This includes pipeline design through or near the existing infrastructure.

Fyfe will also undertake onsite surveying and civil design of footings at Darwin LNG as part of the early works process.

Bayu-Undan will initially take CO2 from the Darwin LNG plant as Barossa replaces the field as backfill.

Santos has previously said the reservoir has the potential for future expansion to proximal third parties.

Separate to the EPC contract to Fyfe, Santos' next contract for procurement of long lead valves closes this week.

Santos is seeking expressions of interest from companies who can supply manual ball vales, flanged up to DN600 in size and 15000# pressure rating.

It also requires steel manual triple offset butterfly valves and actuated ball valves and pressure safety valves.
