HOUSTON OKEA has awarded the SLB OneSubsea joint venture and Subsea 7 (Subsea Integration Alliance) an integrated EPCI contract for the Bestla (ex-Brasse) Field development in the Norwegian North Sea.

The two-well project, involving a 13-km subsea tieback to the Brage platform, falls under a frame agreement signed with OKEA in 2017.

SLB OneSubsea will supply the subsea production system, which will include two subsea trees, a two-slot template, an umbilical and a control system.

Subsea7 will install the subsea production system as well as design and install the flowline systems, spools and protection measures, including rock installation.

Bestla was discovered in 2016 and contains an estimated 24 MMboe.

According to SLB, the solution proposed by the Subsea Integration Alliance was the first commercially viable plan submitted for the development. The solution is said to be compliant with NCS2017+ for standardized subsea production systems tailored for application on the Norwegian Continental Shelf. The Subsea Integration Alliance plans to commission fabrication services and manufacturing from local partners in Norway.

OKEA is targeting first oil in fourth-quarter 2026.
