Wintershall DEA makes headway at Norwegian field

Germany’s Wintershall DEA has finished installing subsea pipelines and umbilicals at the Nova field in the Norwegian North Sea, slated to start up in 2021.

The work was completed in waters 360 metres deep by UK-based Subsea 7, Wintershall DEA reported in a statement on August 28. The contractor first installed templates and then laid 65 km of pipelines and 20 km of umbilicals.

This infrastructure will connect Nova with the Neptune Energy-operated Gjoa platform 17 km northeast.

Wintershall DEA operates Nova with a 45% stake, with Cairn Energy holding 20%, Spirit Energy 20% and Edison 15%. Cairn is due to offload 10% of its share to One-Dyas. Nova holds 80mn barrels of oil equivalent, with development costs estimated at krone 9.9bn ($1.1bn).
