SUSTAINABLE E NERGY

FOR A BETTER WORLD P

The M aster of Engineering (Sustainable Energy) program offers engineering and science graduates a unique opportunity to gain a specialist qualification in the rapidly growing area of sustainable energy. The p rogram has a strong applied focus on the full range of energy efficiency and renewable energy technologies including solar thermal, biomass, wind and wave power, and cogeneration and trigeneration. A u nique feature of the program is an innovative approach to setting emerging technologies and technical analysis firmly within the context of economic, environmental, and social evaluation of sustainability. Hence RMIT Masters graduates are uniquely equipped to become effective sustainable energy practitioners in the global industry, governmental, nongovernmental and community-based organisations. Specialists t eaching the program include international experts and award winning Australian researchers.

The p rogram has attracted highly talented students from around Australia and the world who are committed to creating a better world.

During the diamond and navidrilling stage, 20 holes were drilled using Reflex Instrument's HX Navimotor. Also, the company's EZ-Trac was used to survey the bore hole and orientate the HX Navi- motor.

Designed, manufactured and tested according to API 2000 code, these valves utilise the latest technologies to provide protection against positive or vacuum overpressure and prevent air intake, evaporative losses of product and help contain odorous and potentially explosive vapours. Vent to atmosphere or pipeaway models are available in a wide range of materials of construction. Minimum pressure of +/- 22mm WC and a maximum setting of +/- 6500mm WC.

FLAME A RRESTERS

Flame a rresters are passive devices with no moving parts. They prevent the propagation of flame from the exposed side of the unit to the protected side by the use of a 316L stainless steel crimped metal ribbon type flame element. A full range of flame arrester designs including inline, end of line and detonation models in a wide range of materials. All units are designed, manufactured and tested to API 2000, BS7244 and EN12874 specifications.

First s canner delivered to Boddington bauxite mine

HP B illiton's Boddington bauxite mine has taken delivery of the first I-Site 8800 long range laser scanner to emerge from the Maptek produc- tion facility in Adelaide. The scanners are the only 3D terrestrial survey instruments manufactured in Australia. The I-Site 8800 is the next generation of scanning hardware. Maptek said it contains a fully integrated 70 megapixel panoramic digital camera, enabling simultaneous capture of 3D laser point clouds with overlaid photo pixels. The laser scanner can collect 8800 laser points per second at a range of up to 2000m. Boddington Bauxite will use the system for end-of-month surveying and stockpile volumes, mostly picking up multiple open pits for monthly reconciliation. From one setup the laser scanner can acquire over 1.3 million fully surveyed (georeferenced) points in only 5min.

"Population growth may well be the single most important issue facing Australia, and engineers will be at the forefront of ensuring that it will be sus- tainable," Lindsay said. "Therefore we "~ C must participate in the public debate and " LINDSAY & DYNAN highlight the infrastructure that will be needed to accompany the growth. We will have to continually update our policies on water, energy, transport infrastructure etc and there may be new policies spe- cifically relating to the issues associated with population growth."

Climate In r egard to climate change and the question of whether human activity is influencing the climate, Lindsay supports a precautionary approach. "I believe the human influence on the climate is real and we must do whatever is necessary to reduce that influence. Even if I were a sceptic, I would support action as a safeguard against the risk of being wrong. "Put in a different way, we engineers apply factors of safety to our designs to accommodate for the unknowns, such as unexpected loadings, faulty materials and workmanship, even errors in design etc. These safety factors ultimately cost the community a portion of GDP and there is every likelihood that those costs exceed what is being currently talked about as the cost to GDP of a price on carbon.

At the Yarwun alumina refinery, constant bombardment of the cooling plates by abrasive hydrated alumina particles in the slurry was forcing the plant operator to replace some plates as “ frequently as every few days. However, head CSIRO slurry erosion researcher Dr Jie Wu claims that a fresh new approach to erosion management has dramatically reduced the effects. 3 " War" : "Traditional defences by industry against erosion of critical equipment were to build the equivalent of a high wall, to make improvements to the way materials are hardened and to follow up with rou- tine repairs to the damage caused by fine particles flowing in slurry form through a mineral processing facility," said Wu. "What we're working on are smarter ways to minimise damage in the first place, extending the working life of equipment, saving both time and money." Research by CSIRO into erosion so- lution strategies started in 2003 with an initial focus on reducing localised ero- sion, which often occurs in the U-bends of pipes that are continually abraded by sand in mineral slurry which has to

HERITAGE

Engineering heritage r ecognition

for t he Burdekin Bridge

by B rian McGrath

Imost 1 00 guests gathered at Home Hill on the south side of the Bur- dekin River on 5 October as the governor of Queensland, Penelope Wensley, unveiled a marker and infor- mation panel, bestowing Engineering Heritage National Landmark status to the Burdekin River Bridge. The Burdekin Bridge, with its cathe- dral-like steel trusses, was opened in 1957 after a ten-year construction period. It consists of ten 76m Pratt truss main spans and 22 approach spans with a total length of 1103m carrying two traffic lanes, one railway track and a walkway. The bridge sits on a non-solid foun- dation consisting of waterproof concrete caissons sunk 30m below the riverbed level

and 15m below the calculated maximum level of fluidisation of the bed in extreme flood conditions. The riverbed at the site

is sand to a depth of more than 50m. In a departure from riveting, field joints in the trusses were made with high-tensile The b ridge replaced earlier low-level rail and road crossings, eliminating the transport bolts, which enabled simpler and more disruptions which had occurred almost every year. rapid assembly. Subsequently, it led to the development of codes of practice for such bolts. The bridge replaced earlier low-level rail and road crossings, eliminating the transport disruptions which had occurred almost every year. The ceremony was addressed by Graeme Haussmann, an engineer who worked on the bridge. A number of other people who worked on the bridge were also in attendance. The master of ceremonies for the event was Janice Ballard, chair of Engineers Australias Townsville Local Group. After the ceremony guests inspected the nearby Silver Link Interpretive Cen- tre, developed by the Lower Burdekin Historical Society. The centre contains a collection of photographs relating to the c onstruction, opening and life of the bridge.

The ControlLogix L73 and L75 pro- grammable automation controllers (PACs) provide advanced memory, speed and RUN F ORCE SD OK processing capabilities for a wide range of control demands, from high-performance logic and motion to information-intensive process applications. For complex, high-performance motion applications, the devices link with motion drives through Ethernet/IP and SERCOS network interfaces. The controllers are capable of supporting as many as 100 axes, simplifying synchronisation of complex motion applications. The 1GB secure digital card that ships with each controller provides improved data integrity, and faster reads and writes than previous CompactFlash technol- ogy. The ControlLogix L73 and L75 PACs offer 16MB and 32MB of memory respectively. New energy storage modules that ship with each controller eliminate the need for lithium batteries.
