Topside Installed for Norway's Nova Field

UK-based Neptune Energy announced on May 11 the successful lift of the 740-metric tons topside module for the Nova oil and gas development in the Norwegian North Sea.

The topside was placed onto a platform at the Neptune-operated Gjoa field by the world's largest crane vessel, Heerema Marine Contractors' Sleipnir, in three hours. The Nova field itself is operated by Germany's Wintershall Dea, although Neptune operates the nearby Duva and Gjoa P1 fields which are also expected to be tied back to Gjoa in the future.

"The Nova field adds valuable resources, prolongs the life of the platform and increases the profitability of Gjoa’s own production," Neptune's managing director in Norway, Odin Estensen, said. "Electrified with hydro power from shore, Gjoa is becoming the efficient, low-carbon hub she was designed to be."

Nova is due to start production in late 2021 from two subsea templates connected with the Gjoa platform. Its oil will be pumped to the Mongstad terminal via the Troll Oil Pipeline II, while its gas will be delivered using the Far North Liquids and Associated Gas System to St Fergus in the UK. Wintershall has a 45% share in the project, while Spirit Energy has 20%, Edison has 15% and Sval Energi and One-Dyas each have 10%.

Meanwhile, Neptune has a 30% interest in Gjoa, Petoro 30%, Wintershall Dea 28% and Okea 12%.
