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.

The blade measures 88.4 meters in length, with a height of 4.47 meters when loaded onto the truck. Under bridges there was only a gap of three centimeters between the blade and the bottom of the bridge.

A year of planning

Planning started approximately one year before the actual transport. The police, local authorities as well as the Danish road authorities had to be informed about the transport and had to approve all necessary modifications along the route. 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.

Modifications needed to transport the blade safely included changing the positions of traffic signs or the removal of trees. Since the blade’s width and overall height was increased during the planning process, all those modifications had to be adjusted. With the route precisely planned in advance and experts on point temporarily dismantling guardrails and road signs, the transport could be completed successfully thanks to close coordination of all involved parties.

“The transport of the LM 88.4 blade went 100% as planned, even a little faster than expected. A major part of the transport running smoothly was due to long term partner, Arkil Road, Kurt Larsen Storm, taking care of a lot of the planning involving the road authorities and all road modifications such as permanent relocation of traffic signal, temporary removal of traffic signs, and removal of crash barriers allowing the transport to drive against flow of traffic on the motorway. On site Mammoet personnel, Søren Pacholski and Michael Nygaard, as well as escort vehicles drivers did a great job working closely together as “one team” as always. I can only be satisfied with the way the transport went, and the way that people worked together,” said Alex Wagner, Transport & Engineering Manager at Mammoet Wind.
