The power generated at offshore windparks is conducted to the converter stations as direct current (DC). The transformer substation then transforms the direct current into alternating current (AC) which is then supplied into the domestic networks.

We were assigned with the supervision of the transport by SPMT at the different places of handling as well as the supervision of the installation of the 380 mt transformer onto its foundation.

The transformer was manufactured by Messrs. Siemens AG at Erlangen and was transported from Rotterdam to Diele via several inland waterways respectively by road transport.

Our assignment started with discharging the transformer from the inland vessel "MAGDALENA" and loading onto the barge "BROEDERTROUW 2".

For the transport to the port of Leer, the transformer was secured by means of welded chains and stoppers as well as anti-sliding mats.

At the port of Leer the 20-axle SPMT was prepared by mounting it and placing it underneathe the transformer piece by piece. In order to enable this operation the transformer was lifted by means of hydraulic posts.
