Te Mihi Geothermal Power Plant Frame
On Thursday the 8th December 2011, a 25 tonne piece of engineering equipment was transported from Kawerau Engineering to Contact Energy’s new Te Mihi geothermal power plant site near Taupo. The frame looked like a “monster on the truck” being 27 metres long, nine metres wide and weighing 25 tonnes.
Although the frame is not part of the power station itself, it is an essential piece for its construction. The frame is a template to accurately set the generator, condenser and exhaust bearing holding down bolts into position, to place the mentioned mechanical equipment in precise position
It was also essential that the frame was built in a temperature-controlled environment (like our workshop). The tolerance for the positioning of the holes in the foundations is only two millimetres. Putting the frame together outside at the Te Mihi power plant site would not work as the sunshine and varying temperatures would cause the steel to expand and contract, throwing all the measurements off.
Once the frame was completed, we had the dimensions confirmed by a professional surveyor.
