The construction of the wind farm will begin in April.

The Luxembourg-based Jan De Nul NV will be responsible for dredging, seabed construction 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.

“Competence, modern technology and references were the key criteria in the selection of the main contractor for marine construction,” said Arto Huhmarkangas, Project Director, Tahkoluoto Offshore at Suomen Hyötytuuli Oy.

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.

The world’s first offshore wind farm designed for icy conditions will have ten Siemens 4 MW turbines that will be put into operation during the autumn of 2017.
