Offshore/subsea systems
Vår Energi ASA and partners have officially sanctioned the Previously Produced Fields Project in the Greater Ekofisk Area. The redevelopment is expected to add high-value barrels starting in 2028, extending the production life of one of Norway’s key offshore regions.

As HPHT wells push equipment to the edge of material limits, operators are turning to advanced thermoplastics and sealed electrical assemblies to maintain system integrity. From ESP insulation to BOP control systems, the right component design can prevent failures, lower intervention costs, and extend equipment life in the harshest offshore environments.
The new development is estimated to hold 46 million bbl of recoverable oil and is planned to start up in late 2028.
