Tahkoluoto offshore wind farm: Jan De Nul NV main contractor of marine construction works


Wind power producer Suomen Hyötytuuli Oy has chosen Jan De Nul NV, member of Jan De Nul Group, as the main contractor of marine construction for the new offshore wind farm in Pori, Finland. The cable manufacturer Prysmian Finland will supply the undersea cable. Construction of the wind farm will begin in April with the seabed preparation works.

Jan De Nul NV from Belgium, which carries out marine construction and offshore installation works in the energy industry all over the world, will be responsible for dredging, seabed preparation work, and the installation of foundations and wind turbines. The work will take place over the next two summer seasons.

For the first time in Finland, a four-legged jack-up vessel more than 100 metres long will be used in the installation of the wind turbines. Jan De Nul Group has worked in the Baltic Sea before, building an offshore wind farm in Kårehamn, Sweden, in 2013.

“Competence, modern technology and references were the key criteria in the selection of the main contractor for marine construction,” says Arto Huhmarkangas, Project Director, Tahkoluoto Offshore at Suomen Hyötytuuli Oy. “Jan De Nul NV is proud to be selected by Suomen Hyötytuuli Oy to play a key role in the construction of this first offshore wind farm in Finland” added Peter De Pooter, Manager Offshore Renewables within Jan De Nul Group.

Approximately 14 kilometres of a 30-kilovolt undersea cable will be installed on the seabed. The cable is manufactured in Finland by Prysmian Finland.

Construction of the Tahkoluoto offshore wind farm now has five international suppliers involved in the project, Siemens, Technip, ABB, Prysmian, and Jan De Nul NV. The world’s first offshore wind farm designed for icy conditions will have ten 4 MW turbines that will be taken in use during the autumn of 2017.
