The world’s largest crane vessel, “Sleipnir”, safely installed the 740 ton Nova topside module on the host platform Gjøa in the North Sea. The installation is a critical milestone for the Nova project in s progressing towards production start.
The Nova module was built at the Rosenberg Worley yard in Stavanger. A workforce of more than 200 people spent around 420,000 working hours on the module before it was ready to be picked up by Sleipnir in Åmøyfjorden outside Stavanger and then transported to the field for installation.
Nova is located about 120 kilometers northwest of Bergen and approximately 17 kilometers southwest of the Gjøa platform in the Norwegian North Sea, in 370 meters of water
Nova is being developed as a subsea tieback connecting two subsea templates to the existing Gjøa platform operated by Neptune Energy. As host operator, Neptune Energy is conducting all the necessary work related to topside modifications and Installations for the Nova field.
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 meters below sea level and extends the economic lifetime of the existing infrastructure.
