The transformers, which were manufactured by Royal Smit Transformers B.V., weigh no less than 335 tons each. For this project commissioned by TenneT, the specialists at Wagenborg Nedlift had the honour of transporting these five transformers (and accompanying cooling systems) by water and road and then placing them on their foundation.
First of all, three transformers were shipped by barge from Nijmegen to Vierverlaten. The other two were shipped from Schiedam to the far north.
At Vierverlaten, the transformers were unloaded from the barge and onto the heavy-goods dock using a 350-ton crawler crane and a 700-ton mobile crane in tandem.
Starting Monday, 28 June, the transformers were taken to the substation one after the other, using a 16-axle modular trailer. The transformers were then sledged sideways over the foundation directly from the modular trailer and lowered onto the foundation using Wagenborg's new Cube Jack System.
The old proverb is absolutely true: the job went off without a hitch thanks to the expert engineering and project management by Wagenborg’s specialists, as well as the good collaboration with TenneT, Royal Smit Transformers B.V. and the other parties involved in the project.
Dagblad van het Noorden published a nice reportage of this transformator transport.
The Vierverlaten substation is about to become one of the biggest high-voltage substations in the Netherlands. Preparatory work was started way back in 2018 to get the site ready for construction. The substation needs to be expanded with the addition of 380 kV transformers and a new switchyard. Also, the 110 kV and 220 kV stations need to be converted. All the systems will ultimately form a single complete and operational high-voltage substation.
