Introduction
The eWROV by Saab Seaeye is an advanced, all-electric, work-class underwater robot designed to enhance eco-responsibility and efficiency. It represents a significant step in subsea robotics, offering capabilities comparable to hydraulic systems but with reduced environmental impact.

Specifications
The eWROV is a Class III B ROV system with a nominal vehicle power of 180kW (241HP) and a peak power of 200kW (268HP). It has a depth rating of 3,000 msw, extendable to 5,500 msw, and can operate in conditions up to Sea State 6. The vehicle dimensions are 2.8 m x 1.8 m x 1.9 m, with a weight of less than 4,000 kg and a payload capacity of over 250 kg.

Power System
The eWROV features a state-of-the-art DC power transmission system, reducing the size and weight of power subsystems and umbilicals. This system supports smaller, lighter units both topside and subsea, and allows the use of existing client-owned umbilicals.

Advanced Perception Systems
High-precision positioning and advanced situational awareness enable precise vehicle station keeping and target tracking. The system supports automated manipulative tasks with millimetre-level accuracy.

Electric Thrusters and Manipulators
The eWROV's electric thrusters provide 560 kgf, offering superior power efficiency, acceleration, braking, and reversal compared to hydraulic systems. Electric manipulators enhance precision, dexterity, and reliability, supporting both manual and automated operations.

iCON System
The intelligent control of nodes (iCON) system is a modular network providing real-time system control and feedback, facilitating remote and autonomous operations. It simplifies operation, training, and maintenance through a common technology ecosystem.

Operational Modes
The eWROV supports various operational concepts, including onshore control, resident-ready capabilities for long-term immersion, and autonomous operations using the iCON control system.

Performance
The eWROV achieves forward/aft speeds of 2.3 m/s, lateral speeds of 1.5 m/s, and vertical speeds of 1 m/s, with a bollard pull of over 1,200 kgf in all directions. It includes standard auto functions like auto heading, depth, altitude, pitch, and station keeping, with optional advanced perception and AUV behaviors.

Tether Management System (TMS)
The electric Top Hat TMS enhances capability by decoupling ROV from vessel motion, with a depth rating of 4,000 m and a tether capacity of 850 m.

Conclusion
The eWROV by Saab Seaeye is a pioneering all-electric ROV system that combines high performance with eco-responsibility, offering a versatile solution for various underwater operations.
