A 200 tons transformer in hover mode

Next to the giant floating crane the nearly 200 tons weighing transformer almost looked dainty. The transformer was shipped from a plant of one of our customers in Istanbul, a company ranked first in the global nuclear power industry, to Hamburg. The pre-carriage in Turkey was handled by SDV Horoz.

At the relay station Weding the transformer replaces the old system and serves as a connection between the 60,000 volt grid and the 110,000 volt power network of the transmission system operator Eon-Hanse. 

The unloading of the transformer turned out to be a big challenge. Primary mobile cranes should land the heavy load on the dock, but this was not possible as the pressing power of the cranes would have damaged the wharfage. A new solution needed to be found. The SDV Projects experts developed another possibility involving a floating crane which can handle a weight of 600 tons. With this crane the discharge was smoothly executed form the premises of the Flensburger Schiffbau.

The last kilometers of the transport took the longest time. At the point of discharge the transformer was loaded onto a 15-axle flat bed trailer. Additionally the exceptional transport was subject to a police check after their approval the 3 hour journey to the final destination started at 23h00.

As the transformer was not only heavy, but also very big (5m hightx6m width x 11m length) so there had to be made some adjustments to the travel route, like broadening of curves, enhancements of the ground especially at the entry of the construction site and in front of the basement, etc.

The access to the building site at the relay station Weding was without any difficulties. All structural measures were carried out perfectly. Before the transformer could be delivered onto the basement the old transformer had to be dislocated to make room for the new one. 

The delivery onto the basement took another one and a half day. After the 200 tones colossus was jack up on woods the under carriage could be rigged.

 

Trough a rail system the transformer was brought into is final position. The customer was fully satisfied with the performance of the SDV projects team and complimented the team on this logistical masterstroke.
