UK-built underwater survey robot on track

UK-built underwater survey robot on trackA ‘state of the art’ underwater survey robot being developed in the UK, is on schedule for completion early next year after a successful first demonstration. Cumbria-based Forth Engineering hosted ‘Drop One Trials’ of the autonomous underwater system for nuclear inspection at its facility 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. It is part of the Autonomous Aquatic Inspection and Intervention (A2I2) collaborative R&D project supported by Innovate UK under the Industrial Strategy Research Fund and led by Bristol-based Subsea Rovco.

World-leading technologies

The A2I2 consortium is developing various world-leading technologies 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 Engineering, Rovco, D-RisQ, the National Oceanography Centre (NOC), Thales UK and the University of Manchester, have been developing autonomous underwater systems as part of an initiative which brings together expertise from multiple industries and academia.

Rovco has been supporting each work stream with its ground-breaking artificial perception technologies including 3-D computer vision, simultaneous location and mapping, autonomous path planning and scene understanding using machine learning. Rovco’s Intelligent Data Collection System can be integrated into any subsea vehicle to enhance its capability.

ForthD-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.

Meanwhile, 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 Engineering, which has bases 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.

Forth’s programme manager Peter Routledge said: “Underwater robots are increasingly used 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.

Enabling technology

Forth Engineering has incorporated sonar technology with the robot’s system to detect and avoid obstacles underwater to enable the robots to be used near ‘critical infrastructure’. Alongside this, the company has developed an enabling technology which provides launch and recovery, recharging and high-bandwidth communications for the ROV.



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 which can be used by a range of industries without having to stop production.

The company has has also worked with partners on developing the pioneering Hullguard system of protecting floating offshore installations from corrosion without using divers which has been successfully deployed for the first time in the North Sea.

To fast-track other collaborative solutions, Forth Engineering is developing a 68,000ft2 base in Cleator Moor as an innovation hub where products such as FSWbot will be developed.

The company has also been on the frontline when it comes to fighting Covid-19. It has developed a disinfecting robot, and supplied disinfecting cannons, to help a range of industries, businesses and organisations to bring back staff and customers safely. It also gave up its Cleator Moor office space for free during lockdown to charity Scrub Hub North West which delivered essential equipment to local hospitals.
