OneSubsea and oil & gas giants are unlocking deeper waters with all-electric subsea tech

Pushing deeper into offshore frontiers, OneSubsea, a joint venture backed by SLB, Aker Solutions and Subsea7, has cleared a critical path for deepwater development through a joint industry project with France’s TotalEnergies, Norway’s Equinor, the UK’s BP, and the U.S.-headquartered Chevron to master all-electric subsea technology designed to operate 3,000 meters below the surface.

OneSubsea has completed the Brazil All-Electric Joint Industry Project (JIP), a collaboration with TotalEnergies, Equinor, BP, and Chevron, supported through the National Petroleum Agency (ANP) research and development regulation, to advance fully electric subsea production technologies for applications at water depths of up to 3,000 meters.

The subsea player emphasizes that electrification can create new options for designing and operating future deepwater fields by replacing hydraulic actuation with electric systems and connecting subsea equipment, well completion technology, topside controls, and digital capabilities.

The Brazilian project qualified electric components and control systems for deepwater applications and demonstrated an integrated architecture extending electrification beyond the subsea tree, connecting subsea production equipment with electric well completion technology, topside controls, and digital capabilities.
