Under the contract, Hellenic Cables will be responsible for the engineering, manufacturing, testing, and supply of approximately 275 kilometers of 66 kV three-core inter-array cables and the supply of the associated accessories.

The production of the inter-array cables, which is planned to commence next year, will take place at the company’s manufacturing facility in Corinth, Greece.

In June, Seaway7 signed a contract with the developer of the project, ScottishPower Renewables, for the transport and installation of foundations and inter-array cables.
