CABLE SYSTEMS INDUSTRY As the offshore industry is growing fast, Prysmian aims to reach a 30-40% market share. The shift towards 66kV cabling technology is crucial for offshore wind power cost reduction
Technology has been a main engine in the cost reduction campaign that has driven the price of offshore wind energy from €150 per MW/h to under €50/MW/h in just a few short years, chiefly through the upsizing of its turbines. Nowadays, the cabling industry believes further progress in wind offshore cost-reduction could be achieved by the upcoming move to higher voltage levels in both inter- arrays and export cable systems. Prysmian Group, world leader in the energy and telecom cable systems industry with nearly 140 years of experience, sales of over €7.5 billion in 2016, 21,000 employees across 50 countries and 82 plants, is ready to take this opportunity.
INVESTMENT In order to be prepared to support the offshore wind power revolution between 2012-2016, the Group invested around €200m to create

a world-class fleet of vessels – consisting of the Cable Enterprise, Giulio Verne and Ulisse – able to lay cables at all water depths, while approximately €40m was allocated for retooling its production facilities in Pikkala, Finland, Drammen, Norway and Arco Felice, Italy, to handle the manufacture of cables with voltages of up to 600kV.
Raul Gil, Chief Operating officer of Prysmian’s submarine cable business, explained: “The offshore industry is growing fast, with trend closely connected to technological advancements. Even if today the submarine cable infrastructure market is still hinging on 33kV technology, it is clear that the industry is shifting towards 66kV.”
The 66kV cable systems enable twice as much power as 33kV to be transported over a single array cable,
allowing the use of larger turbines and a reduction in the length of cables required, thus decreasing their production and installation costs. This ultimately means lower costs for utility companies and their consumers, as cable industry manufacturing and development set-ups make this technology more efficient and affordable.
HIGH-VOLTAGE FUTURE The group is betting on the high-voltage future of offshore wind developing a HV line — a three-core, 66kV ‘wet- design’ cable system — that is expected to cut the cost of offshore wind inter-array networks by 15%. Prysmian has long-standing leadership and expertise in providing solutions to this industry, being a strategic business partner to the largest TSO companies involved in the development of the offshore industry, as well as the most important developers.
