Smit's largest sheerlegs, Asian Hercules II, has installed a 1,000 tonnes transformer substation module for the world's largest offshore windfarm at Horns Rev off Denmark. The lift was performed on behalf of HBG Steel Structures of the Netherlands, the substation's fabricator.

The Horns Rev windfarm is located some 20km off the west coast of Blavands Huk in the Danish sector of the North Sea. It consists of 80 turbines supplying Denmark's national grid. The 160MW capacity windfarm, owned by Elsam of Denmark, is expected to produce 600 million kW of electricity per year when it commences operation in November.

Asian Hercules II loaded the windfarm's substation at the Port of Esbjerg. The module, measuring 30m by 20m by 15m, sits 14m above sea level on three pre-installed piles measuring 1.6m, 2m and 2.6m in diameter driven 39m into the seabed.

The load out, transportation and installation were all completed within one and a half days.

Smit provided an integrated service package for this project, with its ocean going barge Smitbarge 1 having earlier transported the substation from HBG's yard at Schiedam in The Netherlands to the Port of Esbjerg.
