Prysmian Group has signed a preferred bidder agreement with RWE Renewables for the development of the turn-key high voltage submarine and land export cable connection worth over € 200 million for Sofia Offshore Wind Farm project.
The finalisation of the contract is subject to final negotiations and to the final investment decision by RWE. The 1.4 GW Sofia offshore wind farm is located 195 km from the nearest point on the UK’s North East and sited on the shallow central area of the North Sea known as Dogger Bank. With the contract signature and notice to proceed both expected in Q1 2021, Prysmian Group will be responsible for the design, supply, installation and commissioning of an HVDC symmetrical monopole cable system that will connect Sofia’s offshore converter station with the onshore converter station in Teesside. The project involves more than 440 km of ±320 kV submarine export cables with XLPE insulation, and 15 km of ±320 kV land cables with P-Laser insulation. All submarine cables will be produced at Prysmian Group’s facility in Pikkala (Finland), while the land cables will be manufactured at the Gron plant in France. The offshore cable operations will be performed using the Leonardo da Vinci, Prysmian’s new cable laying vessel. Commissioning of the project is scheduled for late 2024.
