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.
Smart site investigation for offshore energy installations in sand . This project aims to develop a next generation tool for seabed site investigations. It will use free-fall penetrometers, advanced physical modelling and novel probabilistic methods to investigate fundamental science of sand responses at low stress level and generate new interpretation methods. Outcomes of this project include a scientific framework to predict soil design parameters at unsampled seabed locations.

Outcomes of this project include a scientific framework to predict soil design parameters at unsampled seabed locations. A game changer in offshore site investigations, the project will provide cheaper and faster geotechnical site investigation in sand at a time of global increase in offshore energy installations (worth 4 trillion over the next decade).Read moreRead less

ARC Research Hub for Offshore Floating Facilities. This research hub aims to address the critical engineering challenges associated with Australia’s next generation of offshore oil and gas projects. These projects, in remote deep-water locations, will require innovative floating facilities. Using world-leading expertise in metocean, hydrodynamic, geotechnical and reliability engineering, the hub aims to develop the new technologies and analysis methods that are required to make projects safe, efficient and cost-effective. This research will include wave and current forecasting, vessel motion and offloading analysis, riser and mooring longevity and novel anchoring and subsea foundations. This is expected to lead to safer, more economical projects and should develop Western Australia’s role as an oil and gas centre of excellence.Read moreRead less
Modelling and simulation of complex granular flows. Granular flows are of crucial importance in a wide range of problems related to civil infrastructure. These include landslides and similar catastrophic events, often leading to loss of life and property. The project aims to develop new methods for accurate prediction of such events thus allowing for the formulation of efficient mitigation strategies.

This project aims to characterise soils with multilayers for offshore foundation designs. The commonly used site investigation tools, cone, T-bar and ball penetrometers, will be studied using advanced large deformation finite element analysis and novel centrifuge technics. The outcome of this study will provide guidelines to interpret soil layer information and soil design parameters from site investigation data, that is, penetrometers’ penetration resistance profiles. The guidelines will fill the knowledge gap in this area and will provide offshore design engineers with more reliable soil parameters for safer and more economical foundation designs.Read moreRead less
A multi-scale theory of unsaturated porous media under extreme loading. Extreme loading induced by impacts, explosives or earthquakes generates stress wave propagation through unsaturated media; this can lead to rock fracturing and soil liquefaction and severely damage civil, mining and military infrastructures and operations. The project aims to develop a novel experimentally-validated theory, with associated models, for describing dynamic responses of unsaturated porous media subject to extrem ....A multi-scale theory of unsaturated porous media under extreme loading. Extreme loading induced by impacts, explosives or earthquakes generates stress wave propagation through unsaturated media; this can lead to rock fracturing and soil liquefaction and severely damage civil, mining and military infrastructures and operations. The project aims to develop a novel experimentally-validated theory, with associated models, for describing dynamic responses of unsaturated porous media subject to extreme loading. Our continuum framework will allow building constitutive models directly from saturation-dependent contact laws at the micro-scale. This will remove the need to use the site-dependent empirical models and thus give the derived constitutive models truly predictive capabilities.Read moreRead less
