The present paper describes a novel concept of a self-installing offshore wind turbine.

A concept for combined installation of the substructure and turbine in one single operation without the need of expensive installation vessels is described.

The stability of the concept during transport and installation is obtained by two structurally connected standard barges with dimension 92 × 32 m.

The concept proves to be stable with weather window equal HS = 4 m for transport and Hs = 1.5 m for installation in the waiting of more accurate analyses.

A cost saving potential in this early phase of 17% is identified compared to the more common steel jacket solution. The cost saving is related to the installation process.
