Development of advanced deterioration model for the design of stabilised pavement bases. The Australian road network is a lifeline infrastructure that underpins the nation's living standards and economy. Much of these roads have deteriorated and require rehabilitation to get a new lease of life. This project intends to develop advanced methods to extend the lives of these pavements using in-situ recycling of old pavement materials.
Geotechnical engineering solutions for deep-water oil and gas developments. Offshore extraction of oil and gas lies at the heart of Australia's prosperity, but faces escalating challenges in water depths already in excess of 1 km and approaching 3 km. Safe and economic design of seabed systems and pipelines requires novel techniques for assessing the engineering properties of seabed sediments, and for foundation and anchoring systems that must withstand extreme loading conditions.

Offshore extraction of oil and gas lies at the heart of Australia's prosperity, but faces escalating challenges in water depths already in excess of 1 km and approaching 3 km. Safe and economic design of seabed systems and pipelines requires novel techniques for assessing the engineering properties of seabed sediments, and for foundation and anchoring systems that must withstand extreme loading conditions. This project contributes to future exploitation of offshore hydrocarbon reserves, by developing new technology and improved reliability in offshore geotechnical design, with consequential benefits to our economy and in minimising impact on the marine environment.

Application of field penetrometer data to offshore geotechnical design in deep water. Offshore oil and gas extraction is a $17 billion/year industry and a major component of GDP, but facing increasing challenges in Australia as exploration extends into water depths exceeding 1 km.

Offshore oil and gas extraction is a $17 billion/year industry and a major component of GDP, but facing increasing challenges in Australia as exploration extends into water depths exceeding 1 km. In order to develop safe and economic facilities in these environments, solutions to significant technical challenges are required, ranging from new technology to assess the strength of seabed soils, to formulating response models for oil and gas pipelines and shallow foundations or anchoring systems. This project contributes to future exploitation of offshore hydrocarbon reserves while minimising impact on the marine environment; it brings direct benefits to our economy and helps maintain our world leadership in offshore geotechnical research.Read moreRead less

Performance of granular matrix under heavy haul cyclic loading. This project aims to enhance the longevity of roads and tracks based on improved geotechnical design. The demand for safe and durable roads and railways to accommodate faster and heavier traffic has increased steadily in the past decade. This project will research the performance of compacted granular waste (coalwash & flyash) under cyclic loads, particularly relevant to heavy haul industry, from a geomechanics perspective. It will use geotechnical laboratory testing and field monitoring to develop a computational model, incorporating the relevant strength and deformation properties at varied load frequencies. The anticipated outcome is sustainable, more resilient transport infrastructure.Read moreRead less

Summary
Advanced numerical and physical modelling of dynamically penetrating anchors for deep water oil and gas developments. Dynamically penetrating anchors (DPAs) are a recent and promising mooring concept for deep water oil and gas developments. Yet, the application of dynamically penetrating anchors remains limited due to a lack of understanding of their performance during dynamic installation and monotonic pull-out and because there are no robust models to simulate these processes. This project wil ....Advanced numerical and physical modelling of dynamically penetrating anchors for deep water oil and gas developments. Dynamically penetrating anchors (DPAs) are a recent and promising mooring concept for deep water oil and gas developments. Yet, the application of dynamically penetrating anchors remains limited due to a lack of understanding of their performance during dynamic installation and monotonic pull-out and because there are no robust models to simulate these processes. This project will advance numerical and physical models of dynamically penetrating anchors impacting the seafloor and embedding into the sediment, and rotating to align with the mooring line upon pull-out. This will lead to accurate predictions for both installation and operation. Robustness will be ensured by accounting for the actual failure mechanisms, high strain rates, potential anchor diving and characteristics of calcareous silt.Read moreRead less
Investigation of alternative footing shapes to mitigate instabilities during installation of offshore drilling platforms. Spudcan footings are used to support three legged mobile drilling rigs, exploring and extracting oil and gas in water depths of up to 150 metres. Despite efforts by the industry to minimise the risks during rig installation, punch-through incidents (i.e. unexpected rapid penetration of the footings) and bending of the leg whilst installing the spudcan next to a footprint (poc ....Investigation of alternative footing shapes to mitigate instabilities during installation of offshore drilling platforms. Spudcan footings are used to support three legged mobile drilling rigs, exploring and extracting oil and gas in water depths of up to 150 metres. Despite efforts by the industry to minimise the risks during rig installation, punch-through incidents (i.e. unexpected rapid penetration of the footings) and bending of the leg whilst installing the spudcan next to a footprint (pockmark from previous rig installation) continue to occur at an increasing rate, causing economic loss of $5 to50 million per incident. Combining advanced physical and numerical modelling, this project aims to develop optimised spudcan shapes, and corresponding design approaches and guidelines, to mitigate these risks, ensuring safe installation of rigs in hazardous regions.Read moreRead less
Predicting the foundation performance of offshore jack-up drilling rigs in intermediate soils. The research outcomes will be a major step forward in creating safer operations of mobile platforms in our challenging seabed conditions. The new models and guidelines will assist engineers in the efficient expansion of our offshore oil and gas industry, with significant increased investment projected over the next five years.
Estimation of spudcan penetration resistance in stratified soils directly from field penetrometer data and quantification of punch-through risk. Foundations for mobile drilling rigs exhibit significant failure rate in the offshore oil and gas industry, which contributes $22 billion annually to the Australian economy. The project will develop a robust design approach for these foundations, based on field penetrometer data and accounting for the highly stratified nature of offshore sediments.
Dynamic evolution of submarine slides and consequences for offshore developments. Oil and gas developments in deep water are at considerable risk from submarine landslides, which may be orders of magnitude larger than onshore landslides. The project will develop new approaches for modelling the initiation and flow kinematics of submarine slides with the aim of quantifying impact forces on offshore infrastructure.
