Transpower Project

In 2011 Tranzcarr was awarded by Siemens the project to transport and install 8 x 236tonne Converter Transformers for the HVDC Pole 3 upgrade, 4 into Haywards Sub Station and 4 into Benmore Sub Station in. The weight and dimensions of the Transformers required them to be barged across Wellington harbour and discharged onto a temporary berthing structure built by Tranzcarr at Seaview. From there they were taken by road transport to Petone and reloaded onto the ‘beam girder set’ for road haulage along SH 2 to the Hayward site. Tranzcarr also had to offload and place the transformers into position using their Hydraulic ‘lift n lock’ Gantry system together with their Hydraulic Skidding system.


For the Benmore site in Otago the units were offloaded at the the Timaru Port into the beam girder set and road hauled to Benmore. The offload at Benmore included reloading the transformers onto a 10 axle 3file Goldhofer platform trailer to allow access into the switchyard.
