Description
EuroAsia Interconnector Ltd (now Great Sea Interconnector) awarded Nexans a turnkey engineering, construction and installation contract for the HVDC subsea cable system on the Great Sea Interconnector section linking Cyprus and Crete, Greece. Signed in July 2023 and valued at approximately €1.43 billion, the contract covers design, manufacture and offshore installation of a 525 kV HVDC bi‑pole cable system, comprising two parallel mass‑impregnated subsea cables of about 900 km each along the Cyprus–Greece route. The cables are being manufactured at Nexans’ plants in Halden (Norway) and Futtsu (Japan) and installed using the cable‑laying vessels Nexans Aurora and Nexans Skagerrak. This package forms the core transmission asset for the Cyprus–Crete interconnector, enabling up to 1,000 MW at first stage (expandable to 2,000 MW) and creating what is described as the world’s longest and deepest subsea HVDC interconnector.
