SLB has announced the award of a sizeable integrated engineering, procurement, construction, and installation (EPCI) contract by OKEA to its OneSubsea™ joint venture and Subsea7. The contract will see the partnership develop the Bestla (formerly known as Brasse) Project in the North Sea, offshore Norway, specifically to accelerate the subsea tieback delivery to aging platforms for profitable and sustainable marginal field development.
The two-well project, with a 13-km tieback to the Brage Platform, isthe latest to be signed under the frame agreement signed with OKEA in2017 and furthers SLB OneSubsea and Subsea7’s partnership under itsSubsea Integration Alliance.
Early engagement and collaborative field development planningcombined with North Sea compliant configurable equipment will becritical for enabling profitable and sustainable marginal fielddevelopment. SLB OneSubsea will deliver the subsea production systemwhich will include two subsea trees, a two-slot template, an umbilical,and a control system. Subsea7 will install the subsea production systemand design and install the flowline systems, spools, and protectionmeasures, including rock installation.
“We enjoy a long, productive relationship with OKEA, building uponthe successful execution of the Hasselmus development, the first projectunder our Alliance frame agreement, which was delivered on time and onbudget in October 2023,” said Mads Hjelmeland, CEO of SLB OneSubsea.“Reaching this point has been driven by outstanding collaboration acrossall partners. Our ongoing partnership has enabled us to work togetherto simplify the field layout and secure long lead items and vesselcapacity, which will bring the new wells online quickly andefficiently.”
Bestla was discovered in 2016 but today’s solution proposed by SubseaIntegration Alliance represents the first commercially viable fielddevelopment plan submitted for the Brasse development. The solution iscompliant with NCS2017+ for standardized subsea production systemstailored for application in the Norwegian Continental Shelf, and theAlliance will support the local economy by commissioning fabrication andmanufacturing from partners in Norway.
The field is estimated to contain 24 million barrels of oil equivalent, of which two-thirds is oil and the remaining one-third is gas and natural gas liquids. First oil is targeted for Q4 2026.
