4 November 2025 – Energy and marine consultancy ABL has been appointed as marine warranty survey (MWS) services provider to support Hellenic Cables’s installation of the upgraded interconnectors that will improve the energy resilience at Greece’s Ionian islands.
This interconnector project involves the installation of submarine cables between Kefalonia and Zakynthos, and Lefkada and Kefalonia. The project will upgrade the 150kV interconnection between the Ionian Islands, with the aim of enhancing the islands’ energy security and reliability.
Cables, of a total length of 38km will be produced by Hellenic Cables, loaded, transported and installed offshore. The project will be completed in 2026. Hellenic Cables, will oversee the operations with ABL as marine warranty surveyor.
ABL has been awarded the project, following several years of successful collaboration with Hellenic Cables on offshore transportation and installation of Greek interconnectors.
ABL’s operation in France will manage the project, supported by its office in Greece which will provide in-country site attendances and marine surveys of the proposed fleet, and contribute towards the technical document review process.
“We have in the past supported as marine warranty surveyor on several Greek interconnector projects. These are critical infrastructure assets to shore up reliable energy supply and energy resilience between Greece’s many islands. As Greece seeks to accelerate its net-zero goals, these new interconnectors will also be key in supporting the low-cost transmission of renewable energy to more consumers,” says Fabien Thomas, ABL’s country manager in France.
ABL has supported numerous major subsea interconnector projects around the world from feasibility to construction and operations. Recent track record includes Greece’s Lavrio-Serifos and Serifos-Milos interconnectors, Australia’s Marinus Link, France and Spain’s Biscay interconnector, US and Canada’s CHPE interconnector, and the UK and Ireland’s Greenlink interconnector.
ABL is part of the global consultancy ABL Group ASA, which is listed on the Oslo Stock Exchange.
