Video: Fenja Manifold Lift

The template and manifold for the Neptune-Energy-operated Fenja project are currently undergoing factory acceptance testing (FAT) and system integration testing (SIT) in Eydehavn, Norway, as the subsea development ramps up toward planned first oil in 2021.

Watch as a 120-metric-ton production manifold is installed into a 370-metric-ton production integrated template structure.

After testing, the templates and manifolds will be transported to Kristiansund in late July, then transported about 120 kilometers north for installation in the Norwegian Sea in early August. Water depth on site is approximately 325 meters.

Fenja, which is Neptune's first operated field development in Norway, will be a tieback to Njord-A. The 36-kilometer subsea pipeline connecting field and host will be the world’s longest electrically trace-heated pipe-in-pipe.

The development 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 field discovery is estimated to contain 97 mmboe 2P reserves.

TechnipFMC is supplying the manifold, trees, controls, riser bases, ETH-PiP, rigid flowlines, flexible risers, umbilical, installation for the project.

Neptune Energy holds a 30% stake in the field, alongside partners Vår Energi, (45%), Suncor (17.5%) and DNO (7.5%).
