The blades, which are for the Samsung's S7.0 171 7MW offshore turbine, are the biggest to have ever been produced.
SSP transported the first blade from its factory in Kirkeby, near Odense, south-west Denmark to the port of Esbjerg of the west coast of the country.
The evening trip required permission from the traffic authorities to full possession of the freeway. In all the 170 kilometre journey took five hours. The remaining two blades will be delivered tonight and tomorrow.
The prototype of the Samsung S7.0-171 turbine will be tested later this year at the Fife Energy Park in Scotland. The unit is scheduled for commercial release in 2015.
