The new 245 kV HVAC dynamic cable system will ensure that offshore wind projects will benefit from superior resistance, high mechanical performances, and above all, boosted reliability to overcome the extremely challenging conditions at sea caused by the constant stress due to water currents and harsh conditions at sea. Prysmian is the first player in the market to have such a full portfolio of dynamic cable systems, from 72.5 kV inter-array to 245 kV export tail cables.
The 245 kV HVAC dynamic cable was manufactured at Prysmian’s centers of excellence in Pikkala (Finland) and Arco Felice (Italy) and will be the enabler of floating offshore market opportunities in both the Mediterranean and Northern seas.
This achievement was part of Prysmian’s innovation roadmap and follows the successful completion of Gruissan and Provence Grand Large pilot floating offshore wind farms in France, underlining Prysmian’s global leadership in accelerating the delivery of Europe’s energy security and transition.
Champions of Innovation
Prysmian’s role as market leader is enabled by its consistent focus on driving new solutions that set industry standards. This three-year project was led by a cross-country team, bringing together Prysmian’s global R&D know-how with its testing labs in Italy and Brazil—both for electrical and mechanical qualifications—where Prysmian was able to benefit from over 25 years of experience in developing product for oil & gas and umbilical applications, which significantly influenced the development of 245 kV dynamic cable system.
The Technical Details
Electrical and mechanical qualifications were conducted following international standards, including CIGRE TB490 and CIGRE TB862 and were witnessed by a third-party certification body. The qualification program also included a flex fatigue tests to prove the cable’s life-long durability and performance for floating offshore wind applications.
