EOLMED project

The Archimed collaborative venture has been created in response to the EOLMED project, an innovative project to connect off-shore wind turbines installed on floating foundations more than 18 km from the coast. The pooling the know-how of the companies Matière and Ponticelli Frères triggers Archimed to  position itself as a major player in the construction of offshore steel wind turbine floaters, in France and in Europe.
