Local scour below offshore pipelines on calcareous sediments. This project will improve predictions of erosion around subsea structures in calcareous sediment, allowing potential pipeline self-burial. This will reduce the considerable costs currently spent on pipeline stabilisation and increase the viability of Australia's offshore resources and the competitiveness of the Australian oil and gas industry.
Predicting scour and scour-induced settlement of subsea infrastructure. This project aims to develop improved predictions and understanding of the potential and extent of scour and scour-induced settlement of subsea infrastructure on mobile seabeds. This is expected to enable scour and settlement to be accounted for directly in engineering stability and serviceability design, overturning current practice which ignores both effects on the basis of using scour protection and costly maintenance and ....Predicting scour and scour-induced settlement of subsea infrastructure. This project aims to develop improved predictions and understanding of the potential and extent of scour and scour-induced settlement of subsea infrastructure on mobile seabeds. This is expected to enable scour and settlement to be accounted for directly in engineering stability and serviceability design, overturning current practice which ignores both effects on the basis of using scour protection and costly maintenance and remediation. Development of accurate predictions is expected to be achieved through physical model testing, numerical modelling and analysis of field data. Predictions should improve subsea reliability and lead to omission of scour protection in some situations, increasing international competitiveness of our offshore oil and gas industry.Read moreRead less
Novel multiple-constraint model for green buildings and life-cycle analyses. This project aims to develop a multiple-constraint automation model to perform life-cycle analyses for projects in the Australian construction industry. The model will optimise construction methods for green-building implementation and offer a realistic approach to Green-star status achievement. The Life-cycle model analyses for cost, greenhouse-gas emissions and energy consumption allowing the construction methods to b ....Novel multiple-constraint model for green buildings and life-cycle analyses. This project aims to develop a multiple-constraint automation model to perform life-cycle analyses for projects in the Australian construction industry. The model will optimise construction methods for green-building implementation and offer a realistic approach to Green-star status achievement. The Life-cycle model analyses for cost, greenhouse-gas emissions and energy consumption allowing the construction methods to be optimised for minimum environmental impact. Utilisation of the model should significantly shape an organisations’ strategic planning, while a recognised high Green-star status from Green Building Council of Australia will improve their reputation and bring benefits to the construction industry.Read moreRead less
Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entir ....Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entirely new exploration model for deepwater hydrocarbons, 2) provided new expertise and seabed maps for generating a superior marine naval defence capability.Read moreRead less
Intra-household resource allocations of older couples. This project aims to analyse processes and outcomes within older households using national, large-scale representative data and mixed methods research design. In an ageing population where households are becoming responsible for provisioning retirement needs, understanding what happens in older couple households is important. The project expects to influence policy by generating evidence relevant to the design of regulations governing the al ....Intra-household resource allocations of older couples. This project aims to analyse processes and outcomes within older households using national, large-scale representative data and mixed methods research design. In an ageing population where households are becoming responsible for provisioning retirement needs, understanding what happens in older couple households is important. The project expects to influence policy by generating evidence relevant to the design of regulations governing the allocation of superannuation assets, tax incentives for alternative forms of retirement savings, asset and income tests on the Age Pension, and initiatives targeting older Australians’ financial literacy.Read moreRead less
Sulfur Cycling in Toxic Oozes, Microbialites and Petroleum. This project will apply compound specific sulfur isotope analyses to sulfur-rich deposits from extreme environments including sulfidic black oozes (Peel-Harvey estuary); modern microbialites (for example, Shark Bay) and oils/source rocks (established and frontier oil fields). Sulfur isotopic data, integrated with other stable isotopic and molecular data, will greatly assist the study of sulfur biogeochemical cycles and mechanisms of org ....Sulfur Cycling in Toxic Oozes, Microbialites and Petroleum. This project will apply compound specific sulfur isotope analyses to sulfur-rich deposits from extreme environments including sulfidic black oozes (Peel-Harvey estuary); modern microbialites (for example, Shark Bay) and oils/source rocks (established and frontier oil fields). Sulfur isotopic data, integrated with other stable isotopic and molecular data, will greatly assist the study of sulfur biogeochemical cycles and mechanisms of organic sulfurisation at different diagenetic stages or geological ages. The project aims to address national concerns through measuring the respective impact of anthropogenic and natural changes on environments, helping to understand the evolution of life on Earth and contributing to efficient discovery of our natural petroleum systems.Read moreRead less
Modelling and testing corroding reinforced concrete structures. The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion. Our ability to design and monitor such structures is crucial. The first part of the project aims to develop an innovative finite element model to improve the prediction ....Modelling and testing corroding reinforced concrete structures. The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion. Our ability to design and monitor such structures is crucial. The first part of the project aims to develop an innovative finite element model to improve the prediction of both active steel reinforcement corrosion and the time to concrete cracking in a chloride environment. It then plans to develop a non-destructive method, combining ultrasonic waves-based technology and acoustic emission, to detect active steel corrosion before any damage is visible on the structure.Read moreRead less
Public health approach to child abuse and neglect: antecedents, outcomes and international comparisons of trends. Child maltreatment is a significant public health issue. Findings will identify characteristics of at-risk children, families and communities; mental health and juvenile justice outcomes. Findings will be used to develop policy recommendations for intervention and prevention strategies to reduce vulnerability and improve monitoring of maltreatment.
