After one and half years in the making at Rosenberg Worley yard in Stavanger, the 740 tonne topside module for the Nova field development was safely loaded on a barge and prepared for sail away to the Gjøa platform in the North Sea.

The load out completes the fabrication phase for the topside module, which started in November 2018. The work was carried out by Rosenberg Worley.

Dennis L. Dickhausen, Nova Facilities VP, said: “The load out marks another important milestone for Wintershall Dea and the Nova project as we enter into the final phases of the development.”

The next step is to transport the module to the Åmøyfjord outside Stavanger, ready for pick up by Heerema’s Sleipnir in the near future. Sleipnir is the world's largest crane vessel and will transport the module to the Norwegian North Sea and lift it onto Gjøa.

Praising the remarkable One Team spirit in the project, Nova topside Manager, Øyvind Eie, said: “Neptune and Rosenberg Worley have worked hard together with the Wintershall Dea team to complete the Nova module on time, with high quality and minimum carry-over work despite the challenging situation we are in. I am looking forward to achieving the next major Nova milestones together as we proceed towards module installation and finally production start.”

Nova is developed as a subsea tie-back connecting two templates to the Gjøa platform. When Nova comes on stream, the topside module will receive the hydrocarbons from the field and provide the field with water injection for pressure support and gas lift.

About Nova

Nova is located about 120 kilometres northwest of Bergen and approximately 17 kilometres southwest of the Gjøa platform in the Norwegian North Sea.

Partnership: Wintershall Dea (operator 45%), Capricorn Norge AS (fully owned subsidiary of Cairn Energy PLC) (10%), ONE-Dyas Norge AS (10%), Spirit Energy Norge AS (20%) and Edison Norge AS (15%).

Water depth: 370 metres

Development solution: Nova is being developed as a subsea tieback connecting two templates to the existing Gjøa platform which is operated by Neptune Energy. Gjøa will receive the production fluids and provide water injection and gas lift to the Nova field. Oil from Nova will be transported from Gjøa through the Troll Oil Pipeline II to Mongstad, associated gas will be exported via the Far North Liquids and Associated Gas System (FLAGS) pipeline to St Fergus in the UK, supplying the European energy market.

The use of existing infrastructure enables a cost-efficient extraction of the resources in the reservoir at 2,570 metres below sea level and extends the economic lifetime of the existing infrastructure.
