Survey teams are preparing to examine the seabed along the proposed submarine cable route for the Great Sea Interconnector between Crete, Greece, and Cyprus. The French research vessel Abeille Marengo has arrived in Crete and is waiting for authorisation to start work. Greek maritime authorities must issue a Navtex notice defining the survey area before operations can begin.
Route and seabed assessment
The surveys will determine the most suitable cable alignment between the Korakia area of Crete and Cyprus. They will also assess underwater conditions that could affect construction. Italian marine-survey specialist Next Geosolutions Europe will carry out the work for French cable manufacturer Nexans, which is responsible for manufacturing and installing the submarine connection.
The programme will include sonar mapping, magnetic surveys, underwater imaging, geological sampling and seabed drilling. The findings will identify rock formations, obstacles and areas where additional cable protection may be needed. Nexans will use the technical information to finalise installation methods and the precise cable route.
