Offshore wind farm, Sprogø

On behalf of marine contractor Aarsleff, SMIT was involved in the construction of the new Sprogø Offshore Windfarm, west of Copenhagen.

The project called for the participation of SMIT’s semi-submersible transportation barge Giant 4. The 24,000 tons capacity barge was deployed for the fabrication and transport of the turbine foundations for the Sprogø windfarm. Giant 4 acted as a floating construction platform for the concrete foundations at the Polish yard of Swinjousci. A total of eight elements were required and the gravity bases had weights of up to 1,900 tons. On completion of fabrication, Giant 4 departed to site, supported by SMIT tugs. On arrival, the barge ballasted down in preparation of the discharge of the elements on-scene. SMIT’s scope of work also included the engineering of a robust moorings solution to ready the barge to withstand sustained periods of poor weather, and various marine support services on site.
