Gap analysis and hazardous area compliance for a solvent distillation plant.
Falling gas pressures on the gas main to Bulwer Island Power Station required the selection, purchase and installation of fuel gas boost compression. A Howden WCVXN 204/11021 oil flooded, rotary screw compressor which was powered by a variable speed drive and an electric motor was selected to handle the variable turndown of the Power plant.
GPA has provided services for large Scale Solar PV Power Stations at the following locations; QLD Gatton Research Facility, Nyngan Power Station and Broken Hill Power station.
The 30MW Cullerin Range Wind Farm is comprised of 15 wind turbines rated at 2MW each. The project involved the design, construction and commissioning of the wind farm including 132/22kV substation and distribution systems.
The project involved the design, procurement and fabrication of a trommel for use in Cadmium production at the Nyrstar Port Pirie Smelter. The Trommel consists of a sloping bottom rectangular tank, with soft closing lids and support frame, motor, gear box, shaft, shaft seals, internal rotating cage with cage doors, internal cleaning nozzles and tank instrumentation.
BHP Billiton Mitsubishi Alliance (BMA)
The Hay Point Coal Terminal project involved GPA undertaking reviews of equipment and structures, to provide the relevant statutory maintenance and inspection information that allowed BMA to assess changes required for compliance.
GPA performed structural assessments at the Viterra Pt Adelaide storage and shipping facility.
GPA designed a reconfiguration of Energy Resources of Australia’s (ERA) process water pre-treatment plant as part of the Ranger Uranium Mine in the Northern Territory. The reconfiguration was to enable the implementation of the high density sludge treatment process. The project also included designing 15km of brine, permeate, and mine water pipelines.
Nyrstar Port Pirie (NPP) is an integrated multi-metals recovery plant processing a wide range of lead rich concentrates and smelting industry by-products. NPP is one of the world’s largest primary lead smelting facilities and the third largest silver producer. NPP has a 45 MW network and more than 20 substations on-site.
