After greater than two years of meticulous planning and preparation, on behalf of its shopper Prysmian, deugro has began the primary cable drum deliveries for SuedOstLink.
SuedOstLink is operated by the transmission system operator TenneT TSO GmbH. It’s thought of a central part of the power transition and is primarily meant to carry electrical energy from renewable power websites in northern and jap Germany to Bavaria in southern Germany, and from Bavaria to the north. Over the following three-and-a-half years, deugro will ship altogether greater than 800 over 10-meter-long cable drums (Figures 1 and a pair of), with weights of as much as 86 metric tons and a diameter of 4.1 meters, from two storage yards in Kelheim and Regensburg, additionally operated by deugro and its companions, to 120 completely different job websites throughout Bavaria.
The undertaking’s complexity and quite a lot of challenges, together with the technical specs, required meticulous planning, preparation, and shut collaboration with all stakeholders to make sure trouble-free deliveries in line with the undertaking’s schedule and finances.
“Because of the involvement of many various events already within the planning and preparation phases, it was important to coordinate and perceive the opposite stakeholders’ wants. A variety of the stakeholders have naturally by no means been concerned in particular transports earlier than, which required numerous consciousness coaching in quite a few private workshops and common on-line conferences in altering teams,” stated Simon Junker, head of Cable Tasks–Renewable Vitality at deugro Germany.
The most important challenges are the cylindrical form and the burden of the cable drums (Figures 3 and 4), in addition to Bavaria’s hilly panorama, various topography, and infrastructure. Due to this fact, to make sure the protected transportation of the cable drums, a personalized answer enabling the protected load securing and environment friendly unspooling operations concurrently after arrival was developed. A singular reality of the deliveries is that the cable drum is not going to be discharged however keep on the transport configuration throughout the unspooling of the cable.
“Every cable drum is positioned on 4 rollers on which it might rotate evenly throughout unspooling [Figures 5 and 6]. This purpose-built unspooling gadget is versatile and can be utilized for various transport configurations for this undertaking. As a result of the metal of the cable drums is immediately loaded onto the metal of the unspooling gadget, much less friction may be thought of for the calculation of the required load securing. This large problem has been solved by creating an acceptable load securing consisting of chains and a tailored, adjustable kind match designed in collaboration with our companions,” stated Junker.
On account of Bavaria’s hilly panorama, and the strongly various topography and infrastructure, for almost all of the route, intensive site visitors administration measures—together with civil works alongside the route to increase and strengthen streets and turns, to move rotaries and take care of peak obstacles like lifting electrical energy strains, to show or dismantle site visitors lights and bypass bridges—should be organized.
One other specialty of the undertaking is that the drums have to be transloaded on their method to the job websites onto self-propelled PSTs or low-bed trailers, that are shorter however, with a transport peak of roughly 5.40 meters, a lot larger than vessel girder bridges. These are longer however decrease and due to this fact appropriate for freeway transport to transit beneath overpasses.
The rationale for the transloading is the size of the entire transport configuration of about 40 meters, which hinders the configuration from passing by the slender streets of small Bavarian villages. As a transloading motion is required for about 50% of the cable drums on their method to the person development websites (Figures 7 and eight), together with their return supply—nonetheless weighing roughly 10 metric tons—to the 2 storage yards, it’s estimated that all the undertaking will contain greater than 2,400 particular person heavy haul transports every requiring particular permits and escorts.
“The sheer measurement of the undertaking with the utilization of a lot particular tools in parallel makes SuedOstLink distinctive for deugro and an actual problem for the a whole bunch of consultants concerned. We’re due to this fact very comfortable that the deliveries of this advanced undertaking have now began, and we’re trying ahead to the profitable cooperation with the completely different groups within the upcoming years to expedite the power transition in Germany,” stated Junker.
