SR20

THE ELECTRIC WORK CLASS ROV EMPOWERING ECO-RESPONSIBILITY

The latest addition to Saab’s underwater portfolio, the Seaeye SR20 eWROV, is a full-sized IMCA Class III B ROV system. Electrification is the key to improved performance, and the SR20 takes electric underwater vehicle capabilities to the next level.

SR20 is the world’s most capable all-electric, work-class underwater robot. With overall power and performance exceeding that of a 200 HP hydraulic equivalent, SR20 delivers maximum capability across all markets and applications, including survey, IMR, construction, drill support and decommissioning. This combined with a compact footprint and increased levels of efficiency reinforces SR20’s position as best in class.

FEATURES

Advanced Control
The SR20 provides the user with a number of control options.  A responsive and flexible control system provides real-time control via a traditional manual joystick, utilising telemetry data delivered in simple human readable formats.  Connection is simplified by use of standard web technologies allowing for low-latency control of the ROV, either via joystick commands or nudge commands.

Environmentally Considerate
The goal of carbon neutrality is a growing focus among the global community, and the SR20 has been designed with eco-responsibility in mind. As well as being more efficient, electric systems use limited fluid making the SR20 significantly more environmentally friendly than equivalent hydraulic work-class systems.

Reliable
SR20 is a new generation of robot, designed from the outset with the ability to persist at sea for long durations without human intervention. With new levels of reliability and low maintenance, the SR20 has unprecedented levels of intelligence, equipment and performance.
