Turkey issues navtex for Great Sea Interconnector seabed surveys

On November 10, 2026, Turkey’s directorate-general of coastal safety issued a navtex regarding planned seabed surveys for the Great Sea Interconnector, a project intended to link the energy grids of Cyprus, Greece, and Israel. The notice, effective until March 20, 2027, covers scientific research along two lines to be conducted by the French vessel Abeille Marengo. The announcement follows direct communications from the French government to Ankara last week regarding the planned operations.

The status of this navtex remains a subject of diplomatic contention. While some reports interpret the move as Turkish consent for the project, Cyprus government spokesman Konstantinos Letymbiotis stated that the Turkish action is "of no consequence." He clarified that the Abeille Marengo departed from Heraklion, Crete, based on permits previously issued solely by Greek and Cypriot authorities. Letymbiotis emphasized that no requests for permission were submitted to Turkey, and the vessel's route was determined independently of the Turkish notice. Greek government spokesman Pavlos Marinakis added that the Turkish communication does not constitute legal recognition of the project or the involved parties' claims.
