If horizontal does not work, then do it vertically: Since the lower tower segment of a wind turbine in Denmark could not be transported in a horizontal position, the transport companies needed to come up with something special. They also broke a record while they were at it.

The electrical components had been pre-installed on the tower base of the wind turbine at the factory, so the lower tower segment could not be transported lying on its side as usual. Instead, OCTRA and COORDINADORA, the companies in charge of the transport, came up with a way of transporting the segment in an upright position. According to a press release from the transportation specialist company Mammoet Wind A/S, the 228-tonne tower base was almost 29 metres high.

The 22-kilometre transport from the Danish port of Hanstholm to the test field in Østerild was only feasible using Self-Propelled Modular Transporters (SPMTs). SPMTs are modular vehicles that are equipped with their own drive units. The mobile platforms have at least two axles and are designed to transport very large and bulky cargo.

The three tower sections and the nacelle that Mammoet transported via the roads that the police had cordoned off weighed a total of 700 tonnes. According to the company, this is the heaviest wind power plant transport that has ever been carried out. Segments 2 and 3 weighed 104 tonnes. This is a mid-range weight, and it was possible to transport them in a horizontal position using conventional articulated lorries. Transporting the 420-tonne nacelle required two lorries pulling in front and one pushing in the rear.

Mammoet delivered the last wind turbine components for the extension of the Clyde Wind Farm situated near Abbington, Scotland. Energy supplier SSE is currently extending the existing 152 turbine wind farm with an additional 54 turbines. Mammoet was responsible for the transportation of all the turbine components during the construction of the extension that will be finished later this year.

Specialist for heavy transports Mammoet Wind transported the world’s longest wind turbine blade from Danish Lunderskov to Aalborg over a distance of more than 200 km. The blade was transported from a pilot plant of LM Wind to the Blaest Blade Test Center.

Mammoet recently completed the transportation of a wind energy prototype for a repowering project at the Drantum II wind energy site near Drantum, Denmark. For this project, wind energy consortium Uhre Wind Power charged Mammoet with the transportation operations needed to get the old wind turbine off site and bring the new replacement to its final destination.
