Projects

Geotherm has undertaken a wide variety of thermal resistivity testing projects, from full thermal surveys, backfill designs for large cable installations and QA testing of many cubic meters of cable bedding. The projects have ranged from small surveys where only 1 or 2 tests were required, to 60+ turbine wind farms where hundreds of locations were testing.

Listed below are just some of the projects that Geotherm have undertaken.

PBBeca Joint Venture Victorian Desalination Project

Geotherm developed a flowable bedding/backfill material for the 88km’s of power cable connecting the Victorian Desalination plant to the main Melbourne grid in Cranbourne.

Transgrid Feeder 42

Geotherm undertook all the quality control thermal resistivity testing of the 14:1 stabilised sand backfill material used for the ‘Circuit 42’ project - 26 kilometres of 330kV dual circuit.

Energy Australia Thermal Survey

Geotherm conducted a thermal survey for the proposed cable route from Kogarah to Beaconsfield & Canterbury.

Areva T&D Musselroe Wind Farm

Geotherm were engaged by Areva to undertake a thermal survey across a largefarmland area in Musselroe, North east Tasmania, where a 60 turbine wind farm was proposed.

Ergon Energy Thermal Survey

As part of the Ergon Energy 66kV circuit upgrade to Glenella Substation in Mackay QLD, Geotherm performed a thermal survey on the proposed cable route. The project involved mobilisation to Mackay and the excavation of 10 test pits, most along the freight rail corridor.

Energy Australia East Lindfield 132kV Cable installation

Geotherm were responsible for the collection and testing of the flowable backfill material used during the cable installation of the East Lindfield project. The cable installation was 10km in length from East Lindfield Substation to Willoughby Substation, with the backfill required to be tested every 100meters of trench.
