Leading engineering on the Fram Sør project on the Norwegian Continental Shelf, I’ve had a front-row seat to what I believe is one of the most exciting developments the offshore industry has seen in decades.

Across the North Sea and other offshore basins, marginal fields have long represented both opportunity and frustration. We’ve known the resources were there, but the economics of developing these small, remote reservoirs has been challenging. So, they have remained stranded, despite their importance to energy security and to extending the life of existing fields.

That’s why the industry’s move toward all-electric subsea production systems (SPS) is so important and why Fram Sør stands out as such a milestone.

After nearly 20 years of industry-wide R&D and qualification work, all-electric SPS technology has finally reached the point where it can be deployed at scale.

Last year, SLB OneSubsea was awarded an EPC contract by Equinor to deliver the world’s first large-scale, all-electric SPS for Fram Sør.

For engineers like me who have spent years working with conventional electrohydraulic production systems, the shift to all-electric architecture is a step change.

By eliminating long-distance hydraulic umbilicals and replacing them with electrical cables, we can reduce system complexity and enhance the viability of long-distance tiebacks to marginal fields.

Another key advantage is the reduction in topside modifications. Without hydraulic high-pressure units or extensive piping, the host platform footprint is smaller and retrofit costs are minimized. From a project delivery standpoint, simplicity matters—less intervention, less space, and fewer integration challenges opens doors for developments that would otherwise struggle to get sanctioned.

But the impact extends beyond economics. The deployment of an all-electric SPS is also a meaningful step toward industry decarbonization by enabling more efficient CO2 injection into depleted reservoirs, thereby unlocking new opportunities for cost-effective carbon capture and storage deployment offshore.

The first electrically controlled subsea X-mas (known as eVXT) trees are now under construction, with delivery to Equinor slated for 2028. For many of my colleagues and I, watching this technology progress from concept to field deployment has been remarkable.

Thank you to everyone across SLB OneSubsea and Equinor for supporting this effort! I’m sure it will go down in history as a pivotal moment for all of us.
