Great Sea Interconnector Submarine Cable Successfully Tested at 3 km Depth

Nexans has successfully completed underwater tests of the cable to be used in the Great Sea Interconnector project — an energy connection between Greece, Cyprus, and Israel.

During the testing, the cable was installed and verified at a depth of 3,000 meters underwater, setting a new world record. After recovering the cable, specialists conducted electrical tests and visual inspections, confirming its ability to operate in extreme deep-sea conditions.

The project aims to connect Cyprus to the European power grid. Currently, the island remains the only EU country not linked to the continent's common energy network, which complicates the development of the energy market and the integration of renewable energy sources.

However, the project's implementation timeline remains uncertain. Nexans previously reported that the cable delivery schedule is being revised, and project completion could be pushed into the next decade.

Nevertheless, Michael Damianos stated that the project will not be halted, and Dan Jorgensen confirmed the European Commission's readiness to provide political and technical support for the initiative.
