A2I2 underwater survey robot on target for 2021 launch after successful trials
A2I2 underwater survey robot on target for 2021 launch after successful trials

A state-of-the-art underwater survey robot being developed by a collaboration of companies from across the UK is on schedule for completion in March next year after a successful first demonstration.

Forth Engineering – a world leader in decommissioning innovation – hosted Drop One Trials of the autonomous underwater system for nuclear inspection at its headquarters in Cumbria in August.

Drop Two Trials are now being planned for the beginning of next year, with the project on target to be completed in March 2021.

Autonomous Aquatic Inspection and Intervention (A2I2) collaborative 

Advancement of the underwater survey robot forms part of the Autonomous Aquatic Inspection and Intervention (A2I2) collaborative R&D project, supported by Innovate UK under the Industrial Strategy Research Fund.


The A2I2 consortium, led by Rovco, is developing various world-leading technology for use across multiple sectors, including offshore wind, nuclear, oil and gas, and other industries, which aims to improve safety by reducing risks when working in challenging and hazardous environments.


Forth, Rovco, D-RisQ, the National Oceanography Centre (NOC), Thales UK and The University of Manchester have been developing autonomous underwater systems as part of a cross-cutting programme, which brings together expertise from multiple industries and academia. 

A convergence of technologies and expertise

Rovco has been supporting each work stream with its groundbreaking, artificial perception technologies, including 3D Computer Vision, Simultaneous Location and Mapping (SLAM), autonomous path planning and scene understanding using Machine Learning (ML). Rovco’s Intelligent Data Collection System can be integrated into any subsea vehicle to enhance its capability.

D-RisQ brings advanced automated software development tools to safety-critical, security-critical and business-critical systems developers. D-RisQ has used these tools to develop high integrity, autonomous decision-making, safety-critical software for this demonstrator that enables the autonomous operation in accordance with regulatory requirements.

The University of Manchester is developing wireless underwater communications, which will ultimately eliminate the need for a tether, allowing the robots developed in A2I2 to operate more freely in hazardous environments. 


Forth, which has three bases in Cumbria – at Maryport, Cleator Moor and Barrow – has built a global reputation for working collaboratively to develop world-first technologies, providing cutting-edge solutions to complex industrial challenges. 

Improving safety, minimising risk 

Forth’s Programme Manager, Peter Routledge said: “Underwater robots are increasingly utilised for commercial and scientific applications to make measurements and interact with underwater assets and the environment. The project’s goal is to develop underwater autonomous vehicles that can improve safety and reduce the challenges of operating in hazardous environments.”

The nuclear use case demonstrator showed how the technology can be used for offshore coring, and wet nuclear storage pond surveys and interactions.


Forth has incorporated sonar technology with the robot’s system to detect and avoid obstacles underwater, in order to enable the robots to be used near ‘critical infrastructure’.  Alongside this, Forth has developed an Enabling Technology that provides Launch and Recovery, recharging and high bandwidth communications for the ROV.

Forth’s innovation pipeline

Forth’s other recent projects include working to develop a world-first Friction Stir Welding Robotic Crawler (FSWbot) for internal repair and refurbishment of pipelines that can be used by a range of industries without having to stop production. It has also worked with partners on developing the pioneering Hullguard system of protecting floating offshore installations from corrosion without using divers – an innovation that has been successfully deployed for the first time in the UK North Sea.

To fast-track other collaborative solutions, Forth is developing its 68,000-square-foot base at Cleator Moor as an innovation hub where products such as the FSWbot will be developed. The company has also been on the frontline when it comes to fighting Covid-19, having developed a disinfecting robot, and supplied disinfecting cannons, to help a range of industries, businesses and organisations welcome back staff and customers safely. In addition, Forth gave up its Cleator Moor office space for free during lockdown to charity Scrub Hub North West, which delivered essential equipment to local hospitals.
