The UK's offshore energy industry is urging the government to designate its assets as critical national infrastructure to bolster security against potential threats from Russia.

The UK’s offshore energy sector is facing heightened security concerns, prompting a call to action from industry leaders. Offshore Energies UK (OEUK) is urging the government to classify offshore assets as critical national infrastructure (CNI) to enhance protection against potential threats, particularly from Russia.
This plea comes amid reports of suspicious drones and vessels near North Sea wind farms and other energy infrastructure. The industry believes that designating these assets as CNI will provide the necessary security measures to safeguard the UK’s energy supply.
Escalating Security Threats in the North Sea
Recent incidents have highlighted the vulnerability of offshore energy infrastructure. Reports indicate that drones have been loitering near offshore installations, raising concerns about potential surveillance or sabotage. These incidents coincide with escalating tensions between Russia and NATO, adding to the urgency of the situation.
Graham Skinner, security policy manager at OEUK, emphasized the need for a review of current designations. He noted that the security landscape has evolved, and the current classifications do not adequately address the new threats. “The designations of critical national infrastructure haven’t changed at the same pace as our security situation has changed,” Skinner stated.
The Importance of CNI Designation
Classifying offshore energy assets as CNI would provide several benefits. It would allow companies to better understand the risks and implement necessary security controls. Additionally, it would integrate these industries into national security conversations and exercises, ensuring a coordinated response to potential threats.
Skinner explained that CNI designation would “allow those companies to really understand what the risks are to their business and what the expectations are from the government in terms of what controls do we need to put in place to protect them.” This designation would also help the government prioritize and protect vital infrastructure, ensuring energy security for the UK.
Industry and Government Response
The industry has already taken steps to address these concerns. In April, ‘Operation Granite Resolve,’ a desktop exercise, tested the offshore industry’s response to simulated threats involving suspicious vessels, drones, and cyber attacks. The exercise revealed that while current security measures are adequate, a small escalation in threats could expose vulnerabilities.
Skinner warned that a coordinated attack on multiple installations could have significant consequences, especially during a cold winter. “We can’t just keep our heads in the sand and think we’re in the same place we were 10 or 15 years ago,” he said, stressing the need for an energy transition that prioritizes national security.
Professor Andrew Neal of the University of Edinburgh highlighted the potential for Russia to target North Sea energy infrastructure. He noted that Russia has spent years mapping undersea energy and data connections, indicating a preparedness for sabotage or cable-tapping. “Russia could definitely target North Sea energy infrastructure,” Neal stated, emphasizing the need for enhanced protection.
The UK government has acknowledged the importance of energy resilience and security. A spokesperson stated, “We work closely with stakeholders, including Offshore Energies UK, to protect vital offshore and subsea energy infrastructure against a range of threats.” However, the industry is calling for more concrete actions to address the evolving security landscape.
