Crete had been planning to connect to the Greek mainland, in order to achieve a more reliable, cheaper and environmentally friendly electricity supply.
The Crete-Peloponnese Interconnector is also known as the 'Interconnection of Records': two submarine AC cables of about 135 km each as well as 42 km of underground AC cables on land, connect Cretan Chania with Neapoli on the mainland.
Tobias Boderé, Project Manager at Jan De Nul Group: "A challenging seabed with rough rocks, cable tensions of 75 tonnes, large water depths of up to 1 km and the installation of an unprecedented length of cable in very challenging adverse weather conditions: all thanks to the tireless efforts of our crew on board the Isaac Newton, we have bridged these 135 km. Together we successfully delivered the installation of one of the most challenging interconnectors in the world."
Due to the proximity of the 'Hellenic Trench' fault line, the seabed between Crete and the Greek mainland is very rough with steep cliffs. Jan De Nul installed several types of protective material to protect the cable, ensuring its stability and durability. The cable route was optimised and the different types of customised cable protection systems (CPS) were successfully installed.
Thanks to the tireless efforts of our crew on board the Isaac Newton, we have successfully bridged the 135 km distance and successfully delivered the installation of one of the most challenging interconnectors in the world!
