This new era prioritizes low-carbon operations, reduced vessel time, and smarter, more autonomous systems. Traditional hydraulic robotics, though powerful, are increasingly out of step with these goals. In their place, electric systems are emerging as the future— not only for their lower environmental footprint but for their agility, reliability, and adaptability to digital workflows. The shift is empowering subsea teams to meet growing operational and environmental expectations with greater confidence and control.
EVOLVING EXPECTATIONS
The shift from hydraulic to electric underwater robotics is more than a technological upgrade—it reflects a broader industry move toward sustainability and performance.
Electric vehicles like Saab’s Seaeye SR20 exemplify how the market is evolving. Engineered for versatility across a wide range of subsea tasks—including inspection, maintenance, repair, survey, construction, drill support, and decommissioning—the SR20 delivers high thrust and tooling capacity in a compact form. It supports an extensive toolkit, from manipulators and torque tools to cutters and survey equipment, without the need for bulky hydraulic infrastructure.
Its modular electric design offers precise control, reduced maintenance, and simpler mobilization. A smaller footprint also allows for deployment from a range of vessels, supporting goals to minimize crew, vessel days, and emissions.
With a depth rating of 2,000 meters and a robust construction built to endure tough offshore conditions, the SR20 meets the rising demand for high-performance vehicles that don’t compromise efficiency or sustainability.
PROGRESSING REMOTE OPERATIONS
Another trend gaining momentum is the integration of underwater robotics into digital and semi-autonomous workflows. Operators are increasingly looking for systems that can interfere with advanced control technologies, enable remote supervision, and eventually support resident subsea operations. The SR20 is built with this evolution in mind. Its electric architecture provides a natural platform for integration with digital navigation and control systems, the groundwork for future capabilities.
As the offshore energy market continues to shift, vehicles like the SR20 will be at the center of a new operational model—one defined by cleaner, leaner, and smarter subsea intervention. The energy transition isn’t just happening on the surface. It’s being driven from the seabed up—with technologies that empower teams to lead the change.
