KASSEL, GermanySubsea 7 has completed installation of the subsea pipelines and umbilicals for Wintershall Dea’s Nova project in the Norwegian North Sea.

Initially the contractor placed two templates on the seabed this May in a water depth of 370 m (1,214 ft), before using the Seven Oceans vessel to lay 65 km (40 mi) of pipelines and the Skandi Acergy to install 20 km (12.4 mi) of control umbilicals.

Subsea 7 fabricated the pipelines while Aker Solutions supplied the umbilicals and tie-in systems.

These will connect the Nova field to the nearby Gjøa platform, which will process and export the hydrocarbons, and provide injection water and lift gas for pressure support.

Drilling of the wells is due to start next year, followed by first production in 2021.
