LONDON – Heerema Marine Contractors’ crane vessel Sleipnir has lifted the new 740-metric ton (816-ton) topsides module for Wintershall Dea’s Nova field onto the Neptune-operated Gjøa platform in the Norwegian North Sea.
The installation took three hours to complete. Neptune’s Duva and Gjøa P1 fields will also be tied-back shortly to Gjøa.
Nova, 17 km (10.6 mi) southwest of the Gjøa platform, in a water depth of 370 m (1,214 ft), is under development via two subsea templates. When production starts in 2021, the topsides module will receive the field’s hydrocarbons and send water injection in the other direction for pressure support and gas lift.
The Gjøa field, which came onstream in 2010, has been developed with five subsea templates connected to the semisubmersible platform for processing and export. Oil is exported by pipeline to Mongstad and gas by pipeline to St Fergus on the Scottish east coast.
