Eni CCUS Holding has completed offshore installation of the 1,885-tonne Douglas CCS platform topside in Liverpool Bay, UK — the first purpose-built offshore platform in the world dedicated to carbon capture and storage for industrial decarbonisation.

The joint venture, owned by Eni and Global Infrastructure Partners (part of BlackRock), delivered the platform in under 18 months from initial contract award through a single integrated schedule covering engineering, procurement, construction and commissioning.

Douglas will act as the offshore hub for the Liverpool Bay CO₂ transportation and storage network — the central infrastructure serving the UK's HyNet industrial decarbonisation cluster.

What does the platform actually do?

The platform will receive CO₂ captured from industrial sites across north-west England and North Wales. An offshore pipeline grid, repurposed to carry CO₂, will route the emissions into depleted natural gas fields for permanent storage.

Structurally, the facility pairs the 1,885t topside with a 1,755t supporting jacket, secured to the seabed by eight foundation piles weighing a combined 730t.

The installation sits within a wider construction programme across the Liverpool Bay CCS network, which Eni CCUS Holding reports has now reached roughly 50% completion.

How much of the spend stays in the UK?

According to Eni, UK-based supply chains have captured roughly 60% of total project expenditure. Construction activity is supporting more than 2,000 jobs, with 200–300 long-term positions projected over more than 25 years of operations.

A defining feature of the scheme is the pairing of new-build installations with legacy infrastructure. Reusing established offshore assets lets the project draw on existing technical knowledge of the depleted gas reservoirs targeted for storage.

The asset is a flagship initiative within Eni CCUS Holding's portfolio of transport and storage infrastructure aimed at hard-to-abate industrial sectors.

What comes next for Eni?

Separately, Eni secured a new deepwater exploration licence last month in Indonesia's Kutei Basin, taking the Sapukala block with a 100% participating interest.

The watch item for Liverpool Bay remains first CO₂ injection timing as the remaining 50% of the network's construction programme advances.
