Ramboll has been selected by Danish utility Hofor as the owner’s technical engineer and turbine foundation consultant for two Danish offshore wind farms.
Nordre Flint will be established in an area in Oresund 12km east of Copenhagen and will consist of 16-40 turbines with an installed capacity of 160MW.
Aflandshage will be located in Oresund 10 kilometres from the southern tip of Amager and will consist of 25-63 turbines with a total capacity of 250MW.
Aflandshage and Nordre Flint are part of Denmark’s green transition and Copenhagen’s ambition to become the world’s first CO2-neutral capital by 2025.
In total, the two wind farms will result in a CO2 reduction of 75,000 tonnes and cover the power consumption of more than 400,000 households. .
The permission to investigate whether the Aflandshage and Nordre Flint offshore wind farms could be established off the coast of Copenhagen was granted in 2019, and the preliminary studies were completed in December 2020.
Ramboll’s contracts cover all owner’s technical engineering services in the planning and implementation of the two wind farms (assuming authority permits).
This includes procurement, design and construction of the foundations that will support the turbines.
Ramboll has PEAK Wind and JUM-BO Consulting has its sub-consultants.
The engineering consultancy has worked with offshore wind since 1989 and has provided consultancy to more than half of the world’s wind turbines.
Ramboll’s global market director for its offshore wind business Søren Juel Petersen said: “We have specialised experts with market-leading experience and knowledge of developing, establishing and operating offshore wind farms who are geared to handle the commercial, technical and contractual aspects of these projects.
“I am happy that we can make this know-how and experience available to HOFOR.
“From a technical perspective, these projects are both exciting and challenging due to the great variations in soil conditions and water depths and due to the tight timeline of the projects.
“The short timeline is necessary to meet the political ambition to reach carbon neutrality by 2025.”
The two offshore wind farms are expected to be established in 2023-2024 when the results of the preliminary studies, the environmental impact assessment and the public hearings have been assessed by the Danish Energy Agency.
The wind farms will then supply green power for the next 30-35 years to the Greater Copenhagen area where the power consumption is large and expected to further increase in the coming years.
