OneSubsea

OneSubsea provides subsea technology, products, systems, solutions, and services for the subsea oil and gas market. The company operates as a global joint venture formed by SLB, Aker Solutions, and Subsea7, combining reservoir expertise, front-end and system design knowledge, manufacturing scale, and pore-to-process integration capabilities to deliver complete subsea solutions. Its focus falls on improving subsea production economics, cutting emissions in subsea operations, and supporting a sustainable energy future. The work covers the full lifecycle of subsea field development. OneSubsea helps customers with accelerated field delivery, long subsea tiebacks, unlocking marginal fields, subsea gas, subsea CCS, decarbonization, electrification, and subsea power. In field development it offers integrated field development, collaboration tools, subsea concept selection, subsea flow assurance, and subsea EPC(I). It supplies subsea production systems, subsea processing systems, subsea umbilical systems, and swivel and marine systems. Those offerings have been field-proven and aim to make oil and gas recovery more effective and energy-efficient, even for fields far from shore. Its products and systems take in subsea trees, subsea manifolds, subsea wellheads, SPS control systems, subsea connection systems, subsea wet connectors, processing control systems, subsea compression, subsea boosting pumps, subsea separation, subsea metering and measurements, subsea power solutions, subsea cooling, subsea junction box, subsea power hub, subsea substation, subsea water injection, subsea sampling, steeltube umbilicals, power umbilicals and cables, integrated production umbilicals, direct electrical heating systems, swivel stacks, turrets, and submerged loading systems, together with subsea intervention solutions, subsea landing strings, subsea reinjection systems, SWIFT, and subsea decommissioning solutions. Beyond equipment supply, OneSubsea offers life-of-field support through asset performance management and production enhancement, along with subsea intervention and workover, subsea well abandonment, and digital and measurements capabilities. Its digital offerings cover Subsea live and Subsea planner. The company's distinction rests on integrating reservoir knowledge, system design, manufacturing, and services across the subsea value chain, with an eye to lowering cost, reducing carbon intensity, and enabling more complex offshore developments.
