Constraints Mapped

By late 2023, the Green Vein interconnector’s initiators had completed a lengthy preparatory phase focused on confirming whether a viable submarine cable route existed between Egypt and Northern Italy. Over roughly three years, they mapped a feasible path across the Mediterranean Sea specifically to avoid seabed sections deeper than about 3.6 km, a critical technical constraint for cable laying. The work accounted for the current technological limit of submarine power cables (around 2.5 km) and the emerging capability of Prysmian Group to lay cables at depths of about 3.5 km. This route-mapping effort, conducted alongside an environmental review, systematically identified and avoided depth-related and environmental constraints, demonstrating that a technically feasible and environmentally reviewed route for the planned 2,800 km, 3 GW HVDC connection could be established.
