Finland accuses senior crew of Russia-linked vessel in damage of undersea power cable in Baltic Sea

Key Points

• Finnish authorities have accused the master, chief mate and second mate of the Russia-linked oil tanker Eagle S of aggravated criminal mischief and aggravated interference for dragging its anchor and damaging the Estlink-2 undersea power cable between Finland and Estonia on Dec. 25.
• The Eagle S, flagged in the Cook Islands, is part of Russia’s “shadow fleet” of aging, obscurely owned tankers used to evade Western sanctions and operating without Western-regulated insurance, raising environmental concerns.
• Investigators allege the tanker left an almost 100-kilometre drag trail on the seabed before being stopped and escorted to a Finnish port, and have referred their findings to prosecutors for possible charges.
• Although the cable, which can supply about half of Estonia’s winter electricity needs, remained operational, the damage drove up energy prices in the Baltic region and underscored vulnerabilities in critical undersea infrastructure.

HELSINKI (AP) — Finnish authorities have accused senior officers of a Russia-linked vessel that damaged undersea cables last year between Finland and Estonia of criminal offenses related to the wreckage.

They say the oil tanker, the Eagle S, dragged its anchor to damage the Estlink-2 power cable and communication links between Finland and Estonia on Dec. 25. The Kremlin previously denied involvement in damaging the infrastructure, which provides power and communication for thousands of Europeans.

The Eagle S is flagged in the Cook Islands, but has been described by Finnish customs officials and the European Union’s executive commission as part of Russia’s shadow fleet of fuel tankers. Those are aging vessels with obscure ownership, acquired to evade Western sanctions amid the war in Ukraine and operating without Western-regulated insurance.

Russia’s use of the vessels has raised environmental concerns about accidents given their age and uncertain insurance coverage.

For the West, the incidents are a test of resolve in the face of what are believed to be widespread sabotage attacks in Europe allegedly linked to Moscow following its full-scale invasion of Ukraine in 2022.

The Eagle S was carrying 35,000 tons of oil and investigators allege it left a drag trail with its anchor for almost 100 kilometers (62 miles) on the sea bed before it was stopped and escorted to the vicinity of a Finnish port.

The senior officers, whose names were not made public, were the master, the chief mate and the second mate, Finnish police said in a statement Friday. The trio was responsible for the safe passage, navigation and operation of the tanker and are suspected of aggravated criminal mischief and aggravated interference with telecommunications.

“The criminal investigation has examined and assessed, among other things, the extent of their responsibility for the condition of the vessel and the degree to which they should have observed the anchor falling into the sea,” said Detective Chief Inspector Sami Liimatainen, who is leading the case for the National Bureau of Investigation.

The investigators' findings have been referred to Finnish prosecutors for possible charges.

The damage to the Estlink 2, which can provide about half of the electricity needs for Estonia in winter, did not disrupt service, although it did drive up energy prices in the Baltic nations.

The cable is about 90 miles (145 kilometers) long and is located at a depth of 90 meters (295 feet) at its deepest point, across one of the busiest shipping lanes in Europe.

The undersea cables and pipelines that crisscross the sea link Nordic, Baltic and central European countries, promote trade, energy security and, in some cases, reduce dependence on Russian energy resources.
