UK trials robot for subsea pipeline defence

Surge in sabotage attacks across European waters prompts governments to step up critical infrastructure protection

The UK's Royal Navy has trialled a remote operated vehicle to clear unexploded ordnance and tackle sabotage threats against subsea pipelines and cables, according to the Ministry of Defence.

The commercially available ROV, adapted by the Defence Science & Technology Laboratory and commercial partners, can scan the seabed for hazards, carry out controlled bomb disposal and relay video and sonar images back to the operator.

“This unique capability with its sensors, tools and cameras will give operators a real time ability to deal with these underwater hazards in a safe, effective and efficient way,” the ministry said.

A surge in sabotage attacks against subsea infrastructure following the outbreak of the Ukraine war has prompted European governments to step up monitoring efforts around energy infrastructure and telecommunications links.
One of the most high profile incidents was the sabotage of the Nord Stream pipelines which were blown up in 2022, and security analysts consulted by Upstream have flagged the increased risk for subsea pipelines to be mined as part of hybrid warfare being waged by Russia against Ukraine's allies.

The ROV, developed in conjunction with Alford Technologies, Atlantas Marine, Sonardyne and ECS Special Projects, can be launched from a ship or the shore and can operate at depths beyond the reach of divers, creating a safer way to remove hazards from the seabed.

Following the completion of successful trials in Horsea Island, Portland Harbour, South Wales and Norway, the new technology and systems developed will now be deployed with other robots to identify and deal with threats to subsea infrastructure.
