The VideoRay Ally is a compact, highly capable remotely operated vehicle (ROV) designed for versatile inspection and light intervention tasks where manoeuvrability, portability and modularity are essential. Sitting between the Pro 5 and the Defender in the Mission Specialist range, Ally delivers enhanced control and payload capacity in a streamlined, deployable platform.

Built on VideoRay’s proven modular architecture, Ally combines vectored thruster control with high-definition imaging and compatibility with a wide range of tools and sensors. Its balanced design makes it particularly effective in confined spaces, flowing water and complex structures where precision positioning and stable operation are critical.

With shared components, common software and field-swappable modules across the Mission Specialist family, the Ally offers operational continuity, simplified maintenance and scalability. From industrial inspection and utilities work to offshore wind and specialist recovery tasks, Ally provides a dependable, adaptable solution for demanding underwater environments.

Ally Benefits

Why choose the Ally

The Ally offers an ideal balance of capability, portability and modularity—making it a trusted solution for inspection and light intervention tasks where precision, flexibility and rapid deployment matter most. Designed to operate confidently in confined, complex and flowing-water environments, Ally helps teams work more efficiently while keeping systems simple and adaptable.

Whether supporting industrial inspections, utilities work or offshore renewable operations, the Ally delivers reliable performance without the overhead of a full intervention-class vehicle.

With stable four-thruster control and a compact frame, Ally allows operators to maintain accurate positioning in restricted and flowing-water environments—improving inspection quality while reducing operator workload and risk.

Built on VideoRay’s modular Mission Specialist platform, Ally can be rapidly reconfigured with different tools and sensors—minimising downtime and enabling teams to respond efficiently to new tasks without changing systems.

Lightweight, portable and capable of extended tether lengths, Ally supports operations in locations that are difficult to access—delivering greater reach and flexibility without the complexity of larger intervention vehicles.

Defender Features

What helps set it apart

The Defender pairs robust construction with a modular design to deliver high-performance results in demanding underwater environments. Its full HD camera, integrated navigation sensors, and seven thrusters ensure precise control, clear visuals, and reliable data capture across a wide range of subsea tasks.
