Protection of North Sea infrastructure is increasingly being viewed as a defence priority amid concerns over Russian activity.
During a debate on May 28 concerning Scotland’s energy policy, questions were raised about the need to protect strategic installations on the seabed.
The debate took place in the Scottish Parliament, where politicians warned about the security challenges facing underwater infrastructure.
According to Michael Marra, the risk stems from Russian activity in certain areas where important energy and communications links are located, UK Defence Journal reports.
Infrastructure in Focus
Marra also stated that the North Sea is not only an energy resource but also part of the country’s security framework.
“We know that our North Sea assets, where Russian submarines have threatened cable-laying activities in recent weeks, have to be a defence priority,” said Marra during a discussion on energy security.
The United Kingdom and other countries have focused on strengthening patrols around strategically important maritime areas.
This interest is driven by the fact that seabed infrastructure has become the subject of increased scrutiny and monitoring and is increasingly being regarded as part of Europe’s broader defence and security policy, UK Defence Journal reports.
The NATO Mission: “Baltic Sentry”
Marra’s warning comes at a time when the protection of critical underwater infrastructure is playing an increasingly important role in the security planning of NATO member states.
In January 2025, NATO launched the mission Baltic Sentry following a series of incidents in the Baltic Sea in which energy and communications cables were damaged.
The mission was intended to strengthen surveillance of strategically important maritime areas and improve the Alliance’s ability to respond to actions that may threaten European energy and communications infrastructure.
This is being achieved, among other measures, through the increased use of warships, patrol aircraft, and unmanned surveillance systems, according to NATO.
