French research vessel commences surveys for Great Sea Interconnector

On November 12, 2026, the French research vessel Abeille Marengo entered international waters southeast of Karpathos to begin survey operations for the Great Sea Interconnector (GSI), an electric link between Greece and Cyprus. After completing equipment calibration, the vessel, chartered by the French company Nexans, began mapping the seabed to determine the cable route. The Greek Navy is closely monitoring the vessel's progress, with the frigates Nikiforos Fokas and Limnos providing security and oversight in the area.

Turkey's response to the deployment remained low-key, avoiding direct obstruction. The Turkish frigate TCG Gokova, stationed nearby, broadcast a message over the radio claiming the vessel was in an area of the Turkish continental shelf and had Turkey's "consent" to proceed. Greek authorities rejected this premise, maintaining that the vessel is conducting operations within the Greek Exclusive Economic Zone under licenses issued by Athens and Nicosia. Unlike previous incidents involving direct interference, the Turkish vessel did not attempt to perform a standard hailing procedure, opting instead to read a prepared text.

The project is expected to continue despite these geopolitical frictions. While Turkish media outlets have presented the situation as a diplomatic success for Ankara, citing the "consent" narrative, regional authorities treat the operations as proceeding normally. The survey is scheduled to continue, serving as a critical step in ending the electrical isolation of Cyprus.
