C-Lion1 Submarine Cable Fully Restored

The break in Cinia's C-Lion1 submarine cable has been repaired and the direct submarine cable connection between Finland and Germany is back online and fully operational.

The fault in the submarine cable was detected on Wednesday 25th of December 2024 at 6:44 p.m., and the repair work in the Gulf of Finland, southeast of Porkkalanniemi, was completed ahead of schedule on Monday 6th of January at 1.37 p.m (EET).

Although specialized equipment had to be brought in from outside the Baltic Sea, the repair process advanced swiftly. The repair vessel Cable Vigilance was dispatched from France immediately after the fault was detected. Thanks to Cinia's good emergency preparedness and seamless collaboration with authorities, the fault was resolved efficiently.

Investigation into the Cable Damage Continues

The cause of the cable damage remains under investigation. Cinia filed an official request for investigation with Finland's National Bureau of Investigation on 25 December 2024, and the authorities are continuing their investigation. The National Bureau of Investigation will provide updates on the investigation as it progresses.

Cinia demands the seizure of the vessel Eagle S, which has been linked to cable damages in the Gulf of Finland, to secure its claims for compensation. Cinia submitted the application to the Helsinki District Court on Tuesday 7th of January.
