Equinor Energy has let contract to Subsea7 SA for Irpa and Verdande field developments in the Norwegian Sea.
The two projects will be executed via consortium of Subsea7 and DeepOcean.
The Irpa project, in the Aasta Hansteen area at 1,350 m water depth, involves a subsea tieback of about 80 km to the Aasta Hansteen FPSO. Contract scope includes engineering, transportation, and installation of a MEG pipeline, a production riser, umbilical, subsea structures, and tie-ins.
The Verdande project, in the Nordland Ridge area, involves a subsea tieback to existing Skuld field and Norne FPSO infrastructure. Contract scope includes engineering, transportation, and installation of a 7.5-km pipe-in-pipe production pipeline, umbilical, flexibles, subsea structures, and tie-ins.
Project management and engineering will begin immediately at Subsea7’s offices in Stavanger, Norway. Fabrication of the pipelines will take place at Subsea7’s spoolbase at Vigra, Norway, and offshore operations are expected to take place in 2024, 2025, and 2026 using both Subsea7’s and DeepOcean’s fleet of vessels.
Subsea7 puts its share of the contract somewhere between $50-150 million.
