In a significant development, Finnish authorities have detained an oil tanker after it was linked to damage to essential undersea infrastructure in the Baltic Sea, marking another potential threat to communication links between NATO countries. The vessel, named Eagle S and registered in the Cook Islands, is reportedly part of Russia’s so-called “shadow fleet.” This detention follows the unexpected shutdown of the Estlink 2 power cable, which connects Finland and Estonia. The cable went offline precisely when the Eagle S was above it at 10:26 GMT. Preliminary investigations suggest the damage could have been caused by the ship’s anchor, as per Finnish broadcaster Yle.
Beyond the power cable disruption, the incident also caused damage to four telecom lines serving Finland, Estonia, and even Germany. The tanker Eagle S, connected to Russia’s shadow fleet—a network of older vessels allegedly used to bypass global oil export restrictions—was en route from Saint Petersburg to Port Said, Egypt, before Finnish authorities held it. The ship is associated with a Dubai-based logistics firm, Caravella, though attempts to contact the company’s owners have so far been unsuccessful.
Kristen Michal, the Estonian Prime Minister, mentioned that the repair efforts for the affected infrastructure could extend up to seven months. Although the power outage has not yet led to electricity shortages in either Finland or Estonia, Estonia’s armed forces have initiated patrols to safeguard the remaining primary power connection, Estlink 1.
This event is part of a troubling pattern in the Baltic region. Notably, in November last year, two undersea cables were severed—one linking Finland and Germany, and another connecting Lithuania and Sweden. These incidents coincided with the presence of a Chinese-flagged vessel, Yi Peng 3, which was navigating from Russia’s Ust-Luga port.
The United States has expressed support for the ongoing investigation, and NATO Secretary General Mark Rutte has affirmed the alliance’s vigilance over the matter. Meanwhile, Kaja Kallas, the EU’s foreign policy chief, has labeled this incident “the latest in a series of suspected attacks on critical infrastructure,” highlighting the growing concern over hybrid warfare threats in the region.
Finnish authorities continue to explore whether the damage was accidental or deliberate. Notably, the Eagle S had voluntarily stopped in Finnish waters, which has simplified jurisdictional proceedings for the investigators. As the inquiry proceeds, the incident underscores the precariousness of critical infrastructures and the geopolitical tensions surrounding their security.
