Summary

In August 2025, Finnish prosecutors indicted the captain, first officer, and second officer of the tanker 'Eagle S' on suspicion of deliberately damaging multiple undersea cables linking Finland and Estonia at Christmas 2024. The suspected method involved dragging the ship's anchor for about 90 kilometers along the seabed, causing damage estimated at at least 60 million euros to the Estlink 2 power cable and multiple communication cables. The tanker, flagged under the Cook Islands, is believed by the EU to be part of the Russian shadow fleet circumventing oil embargoes imposed due to the Ukraine war. The sabotage posed a serious threat to Finland's energy and communication infrastructure, though alternative routes maintained service. Experts and politicians characterize such attacks as part of Russia's hybrid warfare targeting western countries.

Classification

Confidence: High

Finnish authorities suspect the crew of the oil tanker 'Eagle S' of intentionally causing the damage by dragging the ship's anchor over a distance of 90 kilometers on the seabed. A kilometer-long drag mark and the ship's anchor were found on the ocean floor during investigations. The resulting damage is estimated at a minimum of 60 million euros, representing a serious threat to Finland's energy supply and communications. The tanker 'Eagle S' sails under the Cook Islands flag and is believed to be part of the Russian shadow fleet that helps Russia circumvent international oil embargoes imposed due to the Ukraine conflict. Similar sabotage incidents targeting Baltic Sea energy and communication infrastructures have occurred in the prior year and are viewed as elements of a hybrid war by experts and politicians.",
