Seaway7 installing cables for third North Sea Hornsea zone wind project

Ørsted has contracted Seaway7, part of the Subsea7 Group, to transport and install inter-array cables for the Hornsea 3 offshore wind development in the UK southern North Sea.

The program covers transportation and installation of 192 66-kV cables, with a total length of about 500 km. Offshore activity will begin in 2026.

Previously Seaway7 installed the inter-array for the same client at Hornsea 1 and Hornsea 2.

Earlier this year, Ørsted contracted Balmoral Comtec to provide 400 cable protection systems for the Hornsea 3 wind farm development.
