The successful completion of this project promises to put the Australian oil and gas industry in a leading position in this area. Due to the multi-disciplinary nature of this project, the development of this section of the shipbuilding industry will also stimulate the development in many other areas such as structure dynamics, control sensors, actuators, electronics and control.Read moreRead less
Microstructure characteristics to structural performance: the missing link in geopolymers. Geothermal energy from the deep earth's heat is emissions-free and renewable. Cements often fail in geothermal wells due to extreme temperature cycles. Alternative new geopolymer cements will be studied for trouble-free geothermal operations. Knowledge gained will also add confidence to the use of geopolymer in general construction.

Using Sandwich Pipe for Pipeline Vibration Control. Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage. This project proposes using sandwich pipe to suppress different sources of vibrations that may be experienced during the lifetime of the pipeline.

Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage. This project proposes using sandwich pipe to suppress different sources of vibrations that may be experienced during the lifetime of the pipeline. Analytical, numerical and experimental investigations will be carried out to demonstrate the feasibility of the proposed method. The project aims to develop direct applications for designing pipelines to suppress different sources of vibration and to guarantee the safety of pipelines.Read moreRead less
Prediction and controlling of pipe failures in buried water and gas pipe systems. Australian Research Council has recognised water as a critical resource that must be protected from wastage. Along with water, the supply of gas to communities through extensive buried pipe networks is an essential service. As the pipe systems age, the pipe failures have increased. These failures lead to loss of valuable commodity and inconvenience and health hazard to public and workers. Effective asset manage ....Prediction and controlling of pipe failures in buried water and gas pipe systems. Australian Research Council has recognised water as a critical resource that must be protected from wastage. Along with water, the supply of gas to communities through extensive buried pipe networks is an essential service. As the pipe systems age, the pipe failures have increased. These failures lead to loss of valuable commodity and inconvenience and health hazard to public and workers. Effective asset management tools are urgently required in predicting and controlling pipe failures. A consortium of water and gas suppliers and a team of researchers from Monash University and CSIRO have joined forces to address this problem so that significant social and economic benefits to Australia can be realised.

Thermal-induced unilateral plate buckling of concrete pavements: design and evaluation. The project addresses the upheaval buckling of concrete pavements, which is caused by increasingly frequent heat spells. It will consider both the vulnerability assessment of existing pavements, and the design of new pavements made from low-carbon geopolymer concretes (which are lighter than conventional pavements) against upheaval buckling.
Aggressive corrosion of steel infrastructure in marine environments. Marine corrosion is known to be aggressive, but how aggressive it can be under long term exposures is the critical question for the safety and economics of much industrial infrastructure, including harbour, coastal and offshore oil industry facilities. Bacterial and microbiological activity is known to contribute. However, recent findings have observed very aggressive corrosion also under sterile and apparently benign condition ....Aggressive corrosion of steel infrastructure in marine environments. Marine corrosion is known to be aggressive, but how aggressive it can be under long term exposures is the critical question for the safety and economics of much industrial infrastructure, including harbour, coastal and offshore oil industry facilities. Bacterial and microbiological activity is known to contribute. However, recent findings have observed very aggressive corrosion also under sterile and apparently benign conditions. No theory to explain these observations currently exists. A new hypothesis is proposed that in certain circumstances second-phase constituents of steels will facilitate autocatalytic corrosion under anoxic conditions. This project investigates the problem and explores mechanisms and conditions. Read moreRead less
Microbiological and abiotic marine corrosion of steel in particulate media. This project aims to study the complex interfacial physicochemical interaction between structural steel and inert particles in marine environments, including microbial growth influences. It will use field-testing and electrochemical laboratory experiments to understand the short- and long-term corrosion processes. It will develop mathematical models to predict likely corrosion loss and pitting, based on physicochemical c ....Microbiological and abiotic marine corrosion of steel in particulate media. This project aims to study the complex interfacial physicochemical interaction between structural steel and inert particles in marine environments, including microbial growth influences. It will use field-testing and electrochemical laboratory experiments to understand the short- and long-term corrosion processes. It will develop mathematical models to predict likely corrosion loss and pitting, based on physicochemical corrosion principles. Industry increasingly needs such models to manage major infrastructure not protected against corrosion, including offshore energy systems, coastal structures and buried pipelines. These outcomes are expected to benefit Australian engineering consultants in the offshore energy industry, with potential for large foreign exchange earnings.Read moreRead less

This project aims to deliver a novel composite steel–timber system that alleviates many of the environmental concerns of the industry, while improving efficiency by using lighter materials. It aims to develop a unique composite system comprised of steel I-section beams and prefabricated timber slabs, with shear connection being provided by bolting or screws. The project plans to assess the structural system experimentally and numerically, and to craft guidelines for the safe and efficient design of these members. The novel lightweight composite system would enhance the speed of construction, allow for deconstructability and reuse and, because plantation timber sequestrates carbon dioxide, have a low carbon footprint.Read moreRead less

This project will develop a 'green' sustainable composite steel-concrete building frame system that reduces greenhouse gas emissions throughout the life-cycle of building construction, usage and deconstruction. It will eliminate the use of ordinary Portland cement, which is a major carbon dioxide producer, by using geopolymer concrete made from fly-ash, and will use economic thin-walled, high-strength steel sections. Deconstructability is provided through bolted joints and by using tensioned bolts as shear connectors between the steel skeleton and concrete flooring. This project is underpinned by the extensive background of the candidate, and provides a very timely solution to a major contemporary engineering challenge facing Australia.Read moreRead less
Functionally graded modelling of geopolymer and Portland cement concretes. This project aims to investigate why geopolymer concretes crack less than the Portland cement concretes. Carbon emissions from Portland cement is second only to fossil fuels. Geopolymer may emit less carbon dioxide than Portland cement concrete because it bleeds less and has higher creep. The project will test this hypothesis on geopolymer and Portland cement concretes, and emulate its findings in all types of concretes. ....Functionally graded modelling of geopolymer and Portland cement concretes.
