The timeline of underwater sabotage suspected incidents in the Baltic Sea

After a series of power outages, telecom links and gas pipelines since Russia invaded Ukraine 2022, the Baltic Sea region has been on high alert. The NATO military alliance increased its presence by adding aircraft, frigates and naval drones.

A number of investigations are underway, but no suspects were brought to court.

FEBRUARY: FINLAND - GERMANY TELECOM CANAL

On February 21, the police of Sweden and Finland said they were investigating the suspected sabotage a undersea cable of telecoms in the Baltic Sea. The Swedish coast guard sent a vessel to where the damage was done.

Investigators say that no suspects have been identified so far.

Cinia, the Finnish operator, said that it detected problems with its C-Lion1 cable connecting Finland and Germany "sometime" before. It also confirmed that it received confirmation of damage to the cable even though data traffic continued.

This was the third time within a short period of time that the C Lion1 cable had been damaged. It was previously completely severed back in November and December 2024.

The European Commission announced that it would spend nearly a billion Euros to improve cable surveillance and create a fleet emergency repair vessels.

JANUARY: SWEDEN - LATVIA CABLE

A fibre optic cable undersea connecting the west coast Latvia to the Swedish island Gotland failed on 26 January, triggering an investigation from NATO and local authorities.

Sweden seized the Maltese flagged bulk vessel Vezhen and boarded it on suspicion of gross sabotage.

Navigation Maritime Bulgare, a Bulgarian shipping firm, said the anchor of the Vezhen had fallen to the seabed during high winds. It may have hit the cable but denied any sabotage.

On February 3, a Swedish prosecutor concluded that the breach was accidental and released the vessel.

POWER AND INTERNET CABLINGS FOR DECEMBER, 2024

On December 25, four telephone lines and the Estlink 2 underwater power cable, which connects Finland to Estonia, were damaged.

Finland has seized the Cook Islands Eagle S tanker, on suspicion that it was responsible for the damage caused by its anchor dragging. The ship is also believed to be part of an "shadow fleet", which circumvents sanctions against Russian oil.

The Kremlin has said that the seizure of the ship is not a big deal to them, and Russia previously denied any involvement in such incidents.

The Finnish police reported on December 29, that they found tracks in the water where they suspect the Eagle S damaged the cables. Later, investigators recovered an anchor believed to be from the ship.

The Finnish court rejected the request of Caravella LLC FZ based in the United Arab Emirates to release the ship.

BALTIC TELECOM CABLES: NOVEMBER 20, 2024

On November 17 and 18 two undersea fiber-optic communication cables, located at a distance of more than 200 km (about 100 nautical miles) in the Baltic Sea, were cut. This raised suspicions about sabotage.

The investigators focused on the Chinese bulk carrier Yi Peng 3. An analysis of MarineTraffic showed that the coordinates of the ship matched the time and location of the breaches.

After a diplomatic standoff lasting a whole month, China finally allowed investigators and representatives from Germany along with those from Sweden, Finland, and Denmark to board the Yi Peng 3 on December 21, 2018.

BALTICCONNECTOR PIPE AND CABLES - OCTOBER 20, 2023

The Balticconnector subsea pipeline that connects Finland and Estonia was cut by the Chinese container ship NewNew Polar Bear, according to Finnish investigators, when it dragged its anchor in early October 2023.

The Estonian Police suspect that the ship also damaged telecoms cables linking Estonia with Finland and Sweden between October 7-8 before it hit the gas pipeline while on its way to St Petersburg, Russia.

Estonian authorities claim that China did not fulfill its promise to Finland and Estonia regarding the investigation.

SEPTEMBER: NORD STREAM BLASTS

On September 26, 2022, explosions damaged Nord Stream 1 & Nord Stream 2 which were built by Gazprom across the Baltic Sea to supply natural gas to Germany.

Sweden's investigation found explosive residue on several recovered objects, confirming that it was an intentional act. However, Sweden and Denmark ended their investigations in 2024 without naming any suspects.

Western officials suggested that Moscow had blown up its own gas pipelines. This interpretation was rejected by Russia which blamed the United States of America, Britain, and Ukraine for these explosions which have largely cut off Russian gas from the European Market.

These countries deny involvement.

In August 2024 Germany requested that Poland arrest a Ukrainian dive instructor who was accused of being a member of a team which blew up pipelines. Poland claimed that the man fled the country before being detained.
