Prysmian started installing the export cables in 2023 using its Leonardo da Vinci vessel. This also marked the start of the offshore construction of the 1.4 GW wind farm, whose export cable link runs from the offshore converter platform to a landfall point 220 kilometres away in Redcar, Teesside.

Offshore construction at the Sofia project site, 195 kilometres off the UK coast, is still underway, with more than half of the monopiles installed and the first wind turbines now also in place.
