Tideway completes longest AC offshore wind cable

Tideway completed the export cable installation for Ørsted’s 1.2 GW UK Hornsea Project One offshore wind farm.

With 467 km length, it is the longest AC offshore wind cable ever to have been installed. Additionally, the cable manufacturing and installation were completed months ahead of schedule.

The world’s largest offshore wind farm, located 120km off the Yorkshire Coast, was the first project for Tideway’s new cable installation and multifunctional vessel ‘Living Stone’. With its 10,000-tonne cable capacity and cutting-edge dual-lane cable system, ‘Living Stone’ significantly improves cable installation production rates. The installation scope included laying export cables from three different offshore substations located up to 120 km offshore to the shore via a Reactive Compensation Station, as well as the installation of two interlink cables. Tideway also undertook the boulder removal, pre-sweeping and cable pull-in to the substations, and are completing crossing installation and cable burial.

 

Next stop – Belgium
After the successful installation campaign at Hornsea Project One, ‘Living Stone’ will be mobilised for subsea cable installation for Elia’s ‘Modular Offshore Grid’ in the Belgian sector of the North Sea.
