Subsea 7 S.A. on Friday said it was awarded three contracts by Aker BP for work offshore Norway.
The awards included a major contract (over US$750 million) for Yggdrasil field development project (formerly NOAKA), a large contract (US$300-500 million) for Skarv Satellite Project and a substantial contract (US$150-300 million) for Valhall PWP-Fenris project.
The contract scopes are awarded within the Aker BP subsea alliance framework, a partnership between Aker BP, Subsea7 and Aker Solutions. As part of this framework, Subsea7 will provide flowlines, flexible lines and perform the complete installation scope, and Aker Solutions will provide subsea production systems and umbilicals.
The Yggdrasil field development project, located between Alvheim and Oseberg area in the North Sea, involves multiple subsea tiebacks to the fixed platforms in the Yggdrasil greenfield development, Subsea7 said. The tiebacks will utilise several Subsea7 technologies including pipeline bundles, pipe-in-pipe solutions and Swagelining polymer lined flowlines. Project management and engineering is expected to commence immediately at Subsea7’s offices in Stavanger, Norway and Aberdeen, Scotland. Fabrication of the pipelines is planned to be executed at Subsea7’s spoolbase at Vigra, Norway while bundles will be fabricated at Wester, Scotland. Offshore operations are expected to take place between 2024 and 2027.
The Skarv Satellite project, located in the northern part of the Norwegian Sea, consists of Alve Nord, Idun Nord and Ørn tied back to the existing Skarv floating production, storage and offloading (FPSO) vessel. Project management and engineering will commence immediately at Subsea7’s offices in Stavanger, Norway. Fabrication of the pipe-in-pipe pipelines will take place at Subsea7’s spoolbase at Vigra, Norway and offshore operations are expected to take place between 2023 and 2025.
The Valhall PWP-Fenris project, located in the southern North Sea, involves a tieback from the Fenris unmanned installation to the Valhall production wellhead platform and re-routing of existing gas export and gas lift pipelines to a new platform. Project management and engineering will commence immediately at Subsea7’s offices in Stavanger, Norway and Aberdeen, Scotland. Fabrication of the pipelines will take place at Subsea7’s spoolbase at Vigra, Norway and the bundle fabrication will take place at Subsea7’s site at Wester, Scotland. Offshore operations are expected to take place in 2024, 2026 and 2027.
Subsea7 executes projects and provides services in the offshore energy industry. The company announced in July that it is part of a consortium with Van Oord, which was granted a contract from ExxonMobil Guyana, for the construction and installation of the offshore pipeline and accompanying infrastructure for the Gas-to-Energy project.
