A consortium of Subsea7 and DeepOcean has secured two contracts from Norwegian firm Equinor to support the development of the Irpa and Verdande fields, located offshore in the Norwegian Sea.

The plan for the Equinor-operated Irpa deep-water project is for it to be developed as a nearly 80km subsea tieback to the Aasta Hansteen floating production storage and offloading (FPSO) vessel.

Under the contract, the Subsea7 and DeepOcean consortium will be responsible for the engineering, transportation and installation of a monoethylene glycol (MEG) pipeline, production riser, subsea structures, umbilical and tie-ins.

Located in the Nordland Ridge area, the Equinor-operated Verdande project will be developed through a subsea tieback to the existing Skuld field and Norne FPSO facilities.

The consortium will handle the engineering, transportation and installation, which will include a 7.5km-long pipe-in-pipe production pipeline, flexibles, umbilical, subsea structures and tie-ins, for this project.

Subsea7 Norway senior vice-president Monica Bjørkmann said: “The awards continue our long-standing collaborative relationship with Equinor with a focus on safe, efficient and reliable operations.”

Subsea7 said that the project management and engineering for the projects will immediately begin at its offices in Stavanger, Norway.

Fabrication of the pipelines is expected to be carried out at Subsea7’s spoolbase in Vigra, Norway.

Subsea7 and DeepOcean will use their fleet of vessels to undertake offshore operations scheduled in 2024, 2025 and 2026.

DeepOcean Europe managing director Olaf Hansen said: “We have learnt to know Equinor through many years of close collaboration with their organisation and multiple operations on the Norwegian continental shelf.

“They are a demanding but fair operator that constantly challenges us suppliers to further improve safety and reduce emissions and operating costs.”

Subsea7 regards its shares in the contracts as sizeable contracts, defined as in the range of between $50m and $150m. DeepOcean’s share of the contracts is more than $60m.
