Equinor ASA has let additional contracts for its Northern Lights project. An engineering, procurement, construction, and installation (EPCI) contract was awarded to Subsea 7 and a subsea control system contract for the Oseberg A platform to Aibel.
Subsea 7 will fabricate and lay a 100-km long pipeline that will transport CO2 from the intermediate storage site at Energiparken in Øygarden to the injection well in the North Sea. It also will install a 36-km long umbilical that will connect the injection well to Oseberg field where subsea injection facilities will be operated.
Project management and engineering will be delivered by Subsea 7’s office at Forus, while fabrication of pipes will be done at the Vigra spool base near Ålesund. Planning starts immediately, with main offshore operations scheduled to be carried out in 2022-2023. The contract value is estimated at 500 million kroner.
The Aibel contract is a call-off against the existing Oseberg portfolio agreement signed in July 2020. The scope includes all necessary upgrades to pull in and operate the umbilical system that will connect the platform and the Northern Lights subsea facilities.
Project management and engineering will be performed at Aibel’s offices in Bergen and Stavanger. Prefabrication will take place at the Haugesund yard. Work will begin this month and is expected to be complete in late 2023. The contract value is estimated at 140 million kroner.
Northern Lights is part of the Norwegian full-scale carbon capture and storage (CCS) project 'Langskip' (Longship), supported by the Norwegian government (OGJ Online, Dec. 17, 2020). The project will initially include capture of CO2 from Norwegian industrial capture sources. The Northern Lights project comprises transportation, receipt, and permanent storage of CO2 in a reservoir in the northern North Sea.
