Finland is taking decisive action to safeguard its critical undersea infrastructure by establishing a new maritime surveillance centre in the Gulf of Finland. This strategic initiative, announced by the Finnish Border Guard, aims to protect vital power cables, telecommunications links, and gas pipelines from potential sabotage amidst escalating regional tensions.
Heightened Alert in the Baltic Sea Region
The Baltic Sea area has been on high alert since Russia's full-scale invasion of Ukraine in 2022, with a series of concerning incidents involving undersea infrastructure. These events have prompted NATO to increase its military presence in the region, deploying frigates, aircraft, and naval drones to enhance security.
Recent Interceptions and Preventive Measures
On New Year's Eve, Finnish authorities intercepted a cargo vessel travelling from Russia to Israel on suspicion of sabotaging an undersea telecoms cable. This incident follows previous seizures, including the oil tanker Eagle S in December 2024 and the cargo vessel Fitburg in December 2025, both suspected of damaging cables by dragging anchors.
Mikko Hirvi, Head of Maritime Safety and Security at the Finnish Border Guard, emphasised the need for broader preventive measures. "We are developing, and we have the need for, broader preventive measures, even before any harm has occurred," he stated.
Technological Enhancements and International Cooperation
The new surveillance centre will incorporate advanced technologies, including seabed sensors and artificial intelligence solutions for real-time analysis of maritime traffic. Finland plans to collaborate with other Baltic Sea states and the European Commission, seeking EU funding to support the initiative.
Mikko Simola, commander of the Gulf of Finland Coast Guard District, highlighted the focus on monitoring unusual deviations in vessel speed or course. "For the past year in particular, we have focused on obtaining real-time information about vessel deviations," he explained.
Broader European Security Efforts
This move is part of a joint action plan proposed by the European Commission in February last year, designed to enhance the security of submarine cables across the region. The plan underscores the importance of international cooperation in addressing threats to critical infrastructure.
By seizing suspicious vessels, Finnish authorities have managed to prevent further damage, demonstrating the effectiveness of proactive measures. The gradual development of the surveillance centre will build on the Border Guard's existing capabilities, ensuring a robust defence against future threats.
