Mammoet shows how to move the world’s longest, 88.4m, wind turbine blade

Mammoet Wind (which says the biggest thing they move is time) has successfully transported the world’s longest wind turbine blade from LM Wind Power’s pilot plant in Lunderskov to the Blaest Test Center in Aalborg. Because it is the longest blade in the world, no transport equipment has been previously planned for such scale, so LM Wind Power needed a specialist transport company to carry out this unique operation.

The blade measures 88.4-m long and 4.47-m high when loaded on the truck. Precise planning was essential to this operation as the clearance to pass under bridges measured just three centimeters.

The initial route surveys were conducted based on the preliminary drawings of the blade. Along with the planning, the blade size was increased in terms of width and overall height, which led to transport unit adjustments such as longer overhang due to the movement of the tip support point. All road modifications, like traffic signs positions and removal of trees had changed during the process. All these adjustments have been approved by the local authorities, police and the Danish road authorities. Strong relationships between all involved parties made this a smooth and safe operation.

The transport planning started approximately one year prior to the actual transport. Meetings with the police, local authorities and the road authorities were held on site at different pinch points on the route, discussing the intended methods and expected time for different maneuvers. Close coordination with the authorities and all other parties involved enabled the successful completion of this one of a kind transport. With the route precisely planned in advance and experts on point temporarily dismantling guardrails and road signs the successful completion of the transport represented a proud moment for both Mammoet Wind and LM Wind Power.
