Two converter transformers, each weighing an astonishing 445 tonnes, have been successfully transported to their final destination at the onshore station in Garrel. These transformers are critical components for the BorWin5 offshore grid connection system, and their journey to the installation site was nothing short of extraordinary.
The operation required meticulous planning, given the immense weight and dimensions of the equipment. The journey began in Nuremberg, where the transformers were picked up from the manufacturer. From there, the units were primarily transported by ship to the port of Saterland. This waterborne leg was vital for bypassing many of the logistical challenges presented by traditional land transport. Once they arrived at the port, the heavy-lifting operation began, using an 800-tonne crawler crane to reload the transformers. This step was crucial in ensuring that the cargo was safely and securely transferred.
To avoid potential damage to bridges along the planned route, an alternative path spanning 40 kilometers was selected. This wasn’t just a simple detour; it required the use of a specialized girder beak combination to evenly distribute the weight of the transformers and protect critical infrastructure. In some particularly vulnerable sections, additional axle lines were deployed to reduce pressure on the bridges, ensuring a safe passage throughout.
Transporting such a colossal load posed significant challenges, especially navigating narrow roads with a total convoy length of 82 meters. At times, up to three tractors were used to help manoeuvre the transformers through tight spaces, with several changes in direction required due to road conditions.
“This project was an outstanding team effort,” noted Daniel Köder, Project Manager at Kübler, the company tasked with the transport. “The high weight and demanding route demanded top performance from everyone involved. We’re grateful to our team and to our customer for placing their trust in us.”
