TRANSPOWER HVDC POLE 3 UPGRADE
Machinery Movers worked with Tranzcarr on the project awarded by Siemens to transport and install 8 x 236tonne Transformers into Haywards Sub Station (North of Wellington)) and Benmore Sub Station (Central Otago). 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 transported by road to Petone and reloaded onto the ‘beam girder set’ for road haulage to the Hayward site. Machinery Movers also had to offload and place the transformers into position using the Hydraulic ‘lift n lock’ Gantry system together with their Hydraulic Skidding system.
For the Benmore site in Otago the four units were offloaded at the Timaru Port and road hauled to Benmore. The offload at Benmore included reloading the transformers onto a 10 axle platform trailer to allow access into the switchyard. The project presented additional special challenges due to being undertaken in a live, operating substation.
