Cook Islands Oil Tanker EAGLE S Suspected in Estlink 2 Cable Damage
Finnish authorities suspect the tanker EAGLE S damaged the Estlink 2 cable, cutting capacity from 1,016 MW to 358 MW. An anchor may be to blame. Case labeled aggravated sabotage. Repairs will take months. No major power issues expected. Baltic Sea security concerns grow.
The Cook Islands-registered oil tanker EAGLE S is under investigation by Finnish authorities following the failure of the Estlink 2 electricity cable earlier today. The cable, which transmits power between Finland and Estonia, was damaged, reducing its capacity from 1,016 MW to 358 MW. At the time of the incident, electricity was flowing at a rate of 658 MW from Finland to Estonia.
Incident Details
The EAGLE S was located near the site of the cable failure in Finnish waters. Finnish authorities have reported that the vessel may have lost an anchor, which could have caused the damage. The Finnish Border Guard’s patrol ship Turvahas been monitoring the situation closely and was involved in boarding the EAGLE S.

Investigation Underway
The Finnish National Bureau of Investigation has classified the case as aggravated sabotage. The crew of the EAGLE Sis being questioned, although their nationalities have not been disclosed. Officials are examining evidence, including the ship’s movements and physical damage to the cable.
Impact on Energy Transmission
Despite the outage, authorities in both Finland and Estonia have stated that electricity supplies will not be significantly affected. Repairs to the cable, however, are expected to take several months, highlighting the challenge of maintaining critical infrastructure in the Baltic Sea region.
Context and Previous Incidents
The incident adds to a series of concerns about the security of undersea infrastructure in the Baltic Sea. Last month, Turva was also involved in an investigation related to the Yi Peng 3 case, which involved damage to another key piece of infrastructure.
Next Steps
Authorities will continue to investigate the circumstances surrounding the EAGLE S and its potential role in the Estlink 2 damage. The findings may influence future efforts to strengthen the protection of undersea cables and other critical systems in the region.
