The UK government is working on new laws aimed at imposing stricter penalties on shipowners and operators who deliberately or carelessly damage underwater telecommunications cables. This comes amid rising worries about threats to essential underwater infrastructure and increased Russian activity near these networks.

UK Telecoms Minister Liz Lloyd shared these plans on Friday during a speech at the Royal United Services Institute (RUSI). She announced the intention to update Britain’s 140-year-old subsea cable legislation to create a more modern system that enhances national security.

The proposed changes could lead to much higher fines and stricter criminal penalties for vessel owners and operators who intentionally or recklessly damage subsea internet cables. The government plans to kick off a formal consultation on this later this year.

This initiative is in response to growing concerns in Europe about the vulnerability of underwater infrastructure. One particular incident in April highlighted these concerns when British military forces revealed a covert Russian submarine operation acting suspiciously near vital undersea infrastructure in UK waters.

“Given the increasingly challenging geopolitical landscape, the government is rightly assessing whether the UK’s security and resilience measures are sufficient,” said a government spokesperson.

Subsea telecommunications cables are crucial for global internet connectivity and international trade. The UK government estimates that around £1.4 trillion ($1.9 trillion) in daily transactions rely on this subsea cable network.

The UK is linked by approximately 64 subsea telecommunications cables. While failures of these cables are rare, officials mentioned that about 97% of faults occur due to fishing activities or vessels dragging anchors rather than intentional attacks.

The government is also looking at implementing new security responsibilities for cable owners and operators, which would include taking extra measures to prevent, detect, and respond to security threats. Proposed emergency powers would allow authorities to instruct companies to take protective actions during major incidents affecting subsea infrastructure.

“For acts of sabotage clearly connected to a hostile state, UK laws already allow for life imprisonment in the most serious cases,” Lloyd noted. However, she pointed out that many threats occur in a “grey zone” where intent is hard to prove, making prosecutions difficult.

“The UK has robust protections for our subsea cables, but in an increasingly uncertain world, we cannot afford to be complacent,” Lloyd emphasized. “As hostile actions from Russia and others escalate, safeguarding these cables is more critical than ever for our economy, security, and everyday lives.”

The proposed reforms reflect broader worries among Western governments about the security of underwater infrastructure, including telecommunications cables, pipelines, and electrical connections, following a series of incidents in European waters in recent years.
