The Subsea Integration Alliance, a non-incorporated tie-up between Subsea 7 and SLB’s OneSubsea, has been awarded an integrated engineering, procurement, construction, and installation (EPCI) contract for the Bestla project by the Norwegian continental shelf-focused operator OKEA.
The Alliance’s work on the Bestla project, formerly known as Brasse, will accelerate the subsea tieback delivery to ageing platforms for profitable and sustainable marginal field development. Financial details of the deal were not disclosed, although SLB described the contract as sizeable.
The two-well project, with a 13-km tieback to the Brage platform in the Norwegian North Sea, is the latest to be signed under the frame agreement signed with OKEA in 2017.
Under the contract, OneSubsea will deliver 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 and design and install the flowline systems, spools, and protection measures, including rock installation.
“We enjoy a long, productive relationship with OKEA, building upon the successful execution of the Hasselmus development, the first project under our Alliance frame agreement. Our ongoing partnership has enabled us to work together to simplify the field layout and secure long lead items and vessel capacity, which will bring the new wells online quickly and efficiently,” said Mads Hjelmeland, CEO of OneSubsea.
Bestla was discovered in 2016 but the solution proposed by Subsea Integration Alliance represents the first commercially viable field development plan submitted for the previously named Brasse development.
The field is estimated to contain 24m barrels of oil equivalent, of which two-thirds is oil and the remaining one-third is gas and natural gas liquids. First oil from the field is targeted for the fourth quarter of 2026.
This is the second deal the Subsea Integration Alliance won in Norway in under a week. Namely, the Alliance inked a new long-term collaboration agreement with Equinor and, as part of the agreement, immediately started early concept studies for the Wisting field offshore Norway and Bay du Nord off Canada’s Newfoundland and Labrador. This way any resulting EPCI scopes were reserved for the Alliance if a final investment decision is made. |
