Subsea7 said two contracts have been awarded to a joint venture it has entered into with DeepOcean for the Irpa and Verdande field developments, located in the Norwegian Sea.

The fields are operated by Equinor.

The Irpa field development project, located in the Aasta Hansteen area at 1,350 metres water depth, involves a subsea tieback of approximately 80 kilometres to the Aasta Hansteen floating production, storage and offloading (FPSO) vessel. . The contract scope includes engineering, transportation and installation of a monoethylene glycol (MEG) pipeline, a production riser, umbilical, subsea structures and tie-ins.

The Verdande field development project, located in the Nordland Ridge area, involves a subsea tieback to the existing Skuld field and Norne FPSO facilities. The contract scope includes engineering, transportation and installation of a 7.5-kilometre pipe-in-pipe production pipeline, umbilical, flexibles, subsea structures and tie-ins. 

Subsea7 said project management and engineering will commence immediately at its offices in Stavanger, Norway. Fabrication of the pipelines will take place at Subsea7’s spoolbase at Vigra, Norway and offshore operations are planned to take place in 2024, 2025 and 2026 utilising both Subsea7’s and DeepOcean’s fleet of vessels.

Monica Th. Bjørkmann, Senior Vice President for Subsea7 Norway said: “We are delighted to have been awarded these two contracts by Equinor. The awards continue our long-standing collaborative relationship with Equinor with a focus on safe, efficient and reliable operations.”  

Subsea7 is a Luxembourg-based company providing subsea engineering, construction and other services to the offshore energy industry. It is involved in the Gas-to-Energy project offshore Guyana through a consortium with Van Oord for the construction of an offshore pipeline which will transport natural gas from Exxon’s Liza field to shore.
