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.
Ally Features
What helps set it apart
The Ally combines a compact, modular frame with four vectored thrusters, a 4K tilting camera and integrated depth and heading sensors, giving stable control, clear imagery and reliable data across a wide range of inspection tasks.
Modular Architecture
Easily configurable platform with swappable components for rapid setup and mission flexibility.
Four-Thruster System
Provides full four-axis control for superior manoeuvrability in strong currents and confined spaces.
4K Tilting Camera
Delivers sharp, low-light imagery with a wide field of view—ideal for detailed inspections.
Integrated Navigation Suite
Includes depth, heading, and optional DVL sensors for precise positioning and control.
Extended Depth & Tether Options
Operates up to 1,500 metres with fibre optic tether for long-range missions.
Accessory Compatibility
Supports a wide range of tools and sensors, including sonar and manipulators.
ROV Capabilities
Underwater ROVs you can trust, wherever your mission takes you
VideoRay Mission Specialist Series vehicles are designed and built with flexibility in mind. The modular design enables easy maintenance and seamless integration with a variety of tools for a custom solution to your underwater challenges.
The Mission Specialist Ally has two float block options.
A rounded float block that excels in navigating confined
spaces and where shore power is available. The other is a
squared float block that enables the use of Subsea Batteries.
The Mission Specialist Ally is equipped with an Ultra 4K Smart Camera
that is not just a visual device but an intelligent partner capable of
advanced image processing and autonomous decision-making.
The Mission Specialist Ally is outfitted with four
high-performance Mission Specialist thrusters, delivering
impressive capabilities of 4 knots horizontal thrust, 1.5 knots vertical
thrust, and 1 knot lateral movement.
The Mission Specialist Ally seamlessly integrates with an optional
Reach Alpha manipulator, featuring a spring-loaded mounting system.
This innovative design ensures precise centering of the manipulator
during object retrieval, enhancing vertical thrust efficiency to new heights.
15,2000 Lumen Brightness Lights
Can be equipped with an optional BluePrint Oculus M750d, M1200d or M3000d Sonar.
Enhancing the Mission Specialist Ally's capabilities,
an optional upgrade includes the ability to perform
station keeping by harnessing the power of the
Waterlinked A50 DVL (Doppler Velocity Log)
