Sevan SSP has announced that its concept has been chosen for the Equinor-operated Wisting field in the Barents Sea.
Sevan said it had designed a cylindrical floating production storage and offload (FPSO) vessel, which would take power from shore to lower the overall CO2 emissions from the field.
Wisting is located around 192 miles from the Norwegian mainland, and operated by Equinor with 35%, partnered with OMV Norge (25%), Petoro (20%), Idemitsu Petroleum Norge (10%) and Lundin Energy Norway (10%).
The field is estimated to contain close to 500 million barrels of oil equivalent, Equinor said in November, and added that it expects capital investment in the project to be in the order of NOK 60-75 billion (£5-6.3bn).
The operator said it and its partners plan to make a final investment decision on the project in late 2022.
If an FID is approved, Sevan noted the vessel would be one of the largest projects on the Norwegian Continental Shelf in the coming years.
It would also be the company’s second cylindrical FPSO in the Barents Sea, after the 90m diameter Goliat FPSO, delivered in 2016.
“Sevan is eager to pursue collaboration with all stakeholders to continue the work with greener initiatives and provide the best technical and cost-efficient solution for the Wisting field development project,” said Sevan SSP managing director Alf-Roger Skikstein.
Equinor first awarded contracts for Wisting work in November 2020, bringing in Aker Solutions, KBR, Sevan SSP and Aibel to work on FPSO concept studies.
Sevan’s award follows Aker Solutions’ clinching of the contract for front-end engineering and design (FEED) work for the project, covering topside facilities, living quarters and hull.
Other studies were to FMC Kongsberg Subsea, Technip Norge, Aker Solutions, OneSubsea Processing, IKM Ocean Design, Subsea 7, NOV and Baker Hughes, with the bulk of work to be carried out in Norway.
