Subsea7 Awards Worley Rosenberg Northern Lights Phase 2 Fabrication Contract

Subsea7 has awarded Worley Rosenberg a fabrication contract covering subsea structures and pipe spools for the Phase 2 expansion of the Northern Lights carbon transport and storage project in Norway, an expansion that will raise injection capacity at the Øygarden offshore site from 1.5 million to more than 5 million metric tons per annum.

The scope covers construction of subsea spools and structural assemblies required to connect the expanded offshore injection infrastructure. The award follows Worley Rosenberg's delivery of initial subsea equipment for Phase 1 in 2023, work that secured manufacturing activity at its Norwegian fabrication yards.

The contract value was not disclosed.

What does the award cover?

Worley Rosenberg will fabricate the subsea spools and structural assemblies that tie the expanded injection infrastructure into the storage site beneath the North Sea seabed. The work sits squarely in the contractor's existing Norwegian fabrication footprint. Phase 1 components delivered in 2023 established the firm's position on the project.

Jan Narvestad, Managing Director of Worley Rosenberg, framed the award in terms of both market position and plant utilization. "This award strengthens our position in the growing subsea market and further expands our role in delivering infrastructure that enables large-scale CO2 reduction," Narvestad said.

He added: "The award secures activity for our fabrication facilities and deepens our competitive reach in delivering infrastructure for the energy transition."

Subsea7, the offshore contractor acting as purchaser, did not disclose a delivery schedule for the fabricated components.

How large is the capacity step-up?

The numbers define the project. Phase 1 operates from an onshore receiving terminal at Øygarden, outside Bergen, with processing and storage capacity of 1.5 million tons per annum. Phase 2 will scale total annual subsea injection capacity to more than 5 MTPA — more than a threefold increase on built capacity.

The Phase 2 expansion follows a Final Investment Decision reached in March 2025. That FID marks the line between announced ambition and committed capital, and it is the milestone that triggered the procurement chain now reaching Worley Rosenberg's yards.

The added capacity targets demand from industrial emitters across Europe seeking maritime transport of CO2 and permanent subsea geological storage beneath the North Sea. The project's commercial pipeline already includes agreements such as a 200,000-ton CCS deal with Sweden's Öresundskraft.

Who owns and operates the network?

The Northern Lights joint venture is owned in equal thirds by Equinor, Shell and TotalEnergies. The partnership injected and stored its first commercial CO2 volumes in August 2025, establishing the facility as the world's first operational cross-border, third-party carbon transport and storage network.

The initial phase was developed under the Norwegian Government's Longship CCS umbrella, the state funding framework that underwrote the demonstration-scale first stage. Phase 2 moves the project onto a commercial footing sized for multiple third-party emitters rather than a single demonstration stream.

For the fabrication supply chain, the distinction matters. Phase 1 gave Worley Rosenberg a foothold in 2023. Phase 2, backed by an FID and a capacity target above 5 MTPA, converts that foothold into a multi-year workload across the company's Norwegian facilities.

What happens next?

The milestone that decides execution is delivery of the fabricated subsea structures and spools against the Phase 2 construction schedule, ahead of commissioning of the expanded injection system. Subsea7 holds the integration risk. Worley Rosenberg holds the fabrication risk.

On the demand side, the pace at which European industrial emitters sign transport and storage agreements against the new capacity will determine whether the 5 MTPA target fills. The Öresundskraft agreement, at 200,000 tons, shows the scale of the individual deals now accumulating behind the expansion.
