FORNEBU, Norway — Aker BP has submitted plans for development and operations for three subsea tieback developments in the Skarv area of the Norwegian Sea to Norway’s Ministry of Petroleum and Energy.
Collectively these comprise the Skarv Satellite Project (SSP). Each of the Alve Nord, Idun Nord and Ørn discoveries will be developed via a four-slot template and two wells, tied back to the Skarv FPSO in the northern part of the Norwegian Sea.
Partners are PGNiG, Wintershall Dea and Equinor.
Kristine Gunnarshaug, SSP project manager, said one project team would coordinate the developments to reduce costs and realize delivery synergies. The added production will also extend the lifespan of the FPSO.
Aker BP estimates the total recoverable resources for SSP at about 120 MMboe, mostly gas, with combined investments of NOK17 billion (US$1.72 billion).
Production, which is due to start in third-quarter 2027, will have incremental CO2 emissions of 4.5 kg/boe.
On behalf of the license partners, Aker BP has entered into the following contracts:
- Aker Solutions will supply the subsea production systems. These will include seven standardized vertical subsea trees, Vectus 6.0 based control system modules, topside control systems, three of four slot template and manifolds, one cluster manifold, wellheads, and numerous tie-in and connection systems. Fabrication will be handled mainly in Norway and Brazil, with some deliveries from the UK and Malaysia and subcontracting of steel templates in Poland. Final deliveries are scheduled for the first half of 2025.
- Subsea7 is responsible for SSP’s for subsea umbilical riser flowline component, including one dynamic and five static umbilicals with a total length of about 60 km. The Subsea Alliance between Aker BP, Aker Solutions and Subsea 7 will oversee the activity. Project management and engineering will take place at Subsea7’s offices in Stavanger, and fabrication of the pipe-in-pipe pipelines at the company’s spoolbase at Vigra, Norway. Offshore operations are expected between 2023 and 2025.
- Aker Solutions has a letter of intent to start engineering and procurement related to long-lead items for the topside modifications, to be converted to a full EPCI modifications contract next year following approval for the project. The company and Aker BP will jointly perform this work under their Modification Alliance, with the initial interim phase set to continue through spring 2023.
