How could Elering's deployment of underwater surveillance systems affect Europe?
Increased security of critical subsea cables boosts Europe's energy resilience. The agreement between Elering and Image Soft involves deploying the 3rd Generation UNWAS™ system to protect critical underwater HVDC interconnect cables in the Baltic Sea. This system uses passive acoustic hydrophone-based sensors to provide real-time coverage across hundreds of square kilometers, automatically detecting threats such as sabotage, anchor dragging, and unauthorized interference. Since subsea electricity interconnections are vital to the security of supply in the wider region, this deployment strengthens the overall resilience of Europe's energy grid against maritime threats.

How it reaches Europe
-
Elering, the Estonian national transmission system operator, signed an agreement with a Finnish company to deploy its 3rd Generation UNWAS™ system. This system is designed to protect critical underwater high-voltage direct current (HVDC) interconnect cables in the Baltic Sea against threats such as sabotage, anchor dragging, and unauthorized interference.
The full event1independent outlet -
The UNWAS™ system provides real-time coverage across hundreds of square kilometers, automatically detecting threats like sabotage or unauthorized interference. The reports state that subsea electricity interconnections are vital to the security of supply in the wider region, which is part of Europe.
No report states this step directly. Brind drew it from the reporting on each side of it, so treat it as an informed guess.

Why it matters
Energy security is a foundational pillar of modern European stability. The HVDC interconnect cables in the Baltic Sea are crucial arteries for power flow, and any disruption—whether from natural causes or deliberate sabotage—could lead to widespread power shortages or economic instability across the continent.
This deployment represents a proactive step by a regional operator to mitigate these high-risk maritime threats. It aligns with the broader trend of European nations strengthening their critical infrastructure resilience against emerging geopolitical and environmental risks.
