Project details

Fenja is a subsea development located in the Norwegian Sea 120 km north of Kristiansund. The field discovery is estimated to contain 97 mmboe 2P reserves.

A development plan has been approved that combines two subsea templates with six wells. Three of these will be oil producers, two water injectors and one a gas injector. The gas injector will be converted to a gas producer towards the end of field life.

The project features a tie-back to the Njord-A platform. The 36 km subsea pipeline connecting field and host will be the world’s longest electrically trace-heated pipe-in-pipe.

Project status

As at 24/01/20

Fenja’s overall progress is about 50% complete. All SPS (Subsea Production Systems) components have been delivered and the SURF (Subsea/Umbilicals/Risers/Flowlines) is progressing well. The 2019 installation campaigns were successfully completed, where water and gas injection flowlines were installed and tied-in subsea, and are ready for operation. In addition installations of Umbilical, Templates and Manifolds were completed. Fabrication of the production pipeline (ETH PiP) and related components are ongoing.

Host facilities modifications are ongoing on Njord A at Stord and on Njord B in Haugesund, and tow out to the field is planned for 2020. Fenja drilling operations with West Phoenix are planned to start in spring 2020. Production start up is in 2021.
