Finland to Guard Baltic Sea's Undersea Cables
26 Jan
Summary
- Finland is establishing a maritime surveillance centre in the Gulf of Finland.
- The centre will monitor undersea cables and pipelines for potential sabotage.
- This initiative follows recent incidents involving damaged infrastructure.

Finland is set to launch a new maritime surveillance centre in the Gulf of Finland, bolstering the protection of vital undersea infrastructure. This strategic initiative is a direct response to escalating regional tensions and a series of incidents impacting critical undersea links, including power cables, telecommunications, and gas pipelines, which have occurred since February 2025.
The Finnish Border Guard announced the plan, emphasizing cooperation with other Baltic Sea states and the European Commission. The centre will implement a broader joint action plan proposed by the Commission in February 2025, aiming to enhance the security of submarine cables across the region. Preventive measures will include seabed sensors and artificial intelligence for real-time analysis of maritime traffic.
This development is crucial following recent events, such as a cargo vessel being intercepted in December 2025 on suspicion of sabotaging an undersea telecoms cable. In 2023, a Chinese container ship damaged a gas pipeline and cables. Finnish authorities have since detained two vessels, an oil tanker in December 2024 and a cargo vessel in December 2025, on suspicion of severing undersea cables.
