DNV GL has issued Vattenfall with a project certificate for its 412MW Horns Rev 3 offshore wind farm.
The certificate proves a safe and cost-efficient operation of the largest offshore wind farm in Denmark.
Inspections were carried out over a three-year period and included surveillance of manufacturing, transportation and installation of the various components and witnessing the commissioning of the complete wind farm.
Horns Rev 3 (pictured) is the third phase of offshore wind development at the Horns Rev site, 20-30 kilometres off the Danish Jutland coast.
With its 49 8.3 MW MHI Vestas Offshore Wind V164 turbines, it is capable of powering around 425,000 Danish households and will provide some of the cheapest offshore wind electricity in Europe.
DNV GL executive vice president for renewables certification Kim Sandgaard-Mørk said: “As the largest offshore wind farm in Denmark and one of the most cost-efficient generators of offshore wind power in Europe, Horns Rev 3 highlights Vattenfall’s commitment to enable a fossil-free world.
“DNV GL is proud to have supported them in delivering this remarkable achievement, thanks to a close working relationship with Vattenfall and its suppliers including the wind turbine manufacturer.”
Vattenfall certification engineer Belén Fernández Montes said: “With an annual capacity of 1700GWh per year, Horns Rev 3 is a significant contribution to our vision for fossil free living within a generation.
“We are very pleased that we have now been awarded this certificate for Horns Rev 3 confirming that the wind farm is fit to perform for 25 years.
“We have had a good collaboration with DNV GL, where the evaluation included assessment on the maturity of the turbine design, its manufacturing, installation and commissioning processes as well as assessment of related documentation.”
