Ventyr contracts DNV to certify Norway’s first offshore wind farm

DNV has been awarded a contract by offshore wind developer Ventyr for the Design Certification of the Sørlige Nordsjø II wind turbines and offshore substation

Høvik, Norway – 10 July 2025 – DNV, the independent energy expert and assurance provider, has been awarded a contract by offshore wind developer Ventyr for the Design Certification of the Sørlige Nordsjø II wind turbines and offshore substation — Norway’s first bottom-fixed offshore wind farm. Located in the southern North Sea, near the maritime border with Denmark, Sørlige Nordsjø II is one of Norway’s flagship offshore wind areas. The development area spans approximately 520 square kilometers and is located 200 km from the from the Norwegian south-west coast.

“Sørlige Nordsjø II marks a historic step forward for Norway’s offshore wind ambitions, and we are proud to partner with DNV to ensure the project meets the highest standards from the outset,” says Wim Verrept, Project Director at Ventyr. “Robust certification is essential to delivering safe and sustainable offshore wind infrastructure, and DNV’s experience and technical rigor make them a natural partner for this landmark development.”

“We are very pleased to deliver certification services for this project which represents a key milestone in Norway’s offshore renewables ambition,” says Kim Sandgaard-Mørk, Executive Vice President for Renewables Certification at DNV. “DNV has been closely following the development of offshore wind in Norway and is actively supporting Norwegian authorities and regulators with technical insight and guidance based on decades of experience in certifying offshore wind projects globally.”

“Certification plays a vital role in ensuring the safety, quality, and reliability of offshore wind infrastructure,” explains Anne Lene Haukanes Hopstad, Principal Engineer and Project Manager for the Sørlige Nordsjø II certification scope. “Our certification helps confirm that critical components – such as turbine foundations and substations – are designed to withstand the challenging conditions of the North Sea while meeting Norwegian regulatory requirements and international best practices.”

In the North Sea Outlook Report, DNV predicts over 150 GW of offshore wind capacity in the North Sea by mid-century, positioning the region as the world’s most important offshore energy hub. Projects like Sørlige Nordsjø II demonstrate how industry collaboration, technical excellence, and robust certification processes are driving the next chapter of the energy transition.
