The development of offshore petroleum contributes $25 billion annually to the Australian economy. The majority of our $1 trillion of reserves are currently untapped, being in deep water, remote from shore. This Fellowship will generate a scientific understanding of the mechanics of seabed sediments when disturbed by infrastructure and ocean storms, and lead to procedures for designing the seabed pipelines and facilities needed to unlock Australia's isolated deep water petroleum reserves. These procedures will provide economic solutions for safely transmitting the hydrocarbons to shore. The resulting expertise will enhance Australia's global reputation in offshore geotechnics and engineering and raise the competitiveness of our petroleum industry.Read moreRead less

This project aims to tackle the scientific challenges of using screw piles as foundations for deep water offshore wind turbines. Current foundations for offshore infrastructure developments have reached their limits, and conventional screw piles are designed for land use. This project will use innovative geotechnical methods to develop verified designs, guidelines and numerical tools for predicting the forces required to install screw piles into the seabed and their capacity to resist extreme wind and wave forces relevant to these structures. As foundations cost up to 35% of construction, screw piles will provide significant economic and environmental benefits in reducing costs and unlocking substantial renewable energy from our oceans.Read moreRead less

Vulnerability mapping of hazards and economic loss assessment of offshore oil and gas platforms subject to accidental explosion and fires. In Australia, up to 100 offshore oil and gas wells per year are drilled, but fire and explosion are a risk. This project develops vulnerability maps of offshore platforms subjected to accidental explosions, so that economic loss, environmental and social impact can be effectively assessed based on these factors and mitigation measures can be introduced.

Summary
Fundamental aspects of vertical and horizontal consolidation in a multi-layered soil system. Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After valida ....Fundamental aspects of vertical and horizontal consolidation in a multi-layered soil system. Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After validation using experimental data and numerical simulations, the proposed analytical model can be used to mimic soil behaviour more closely than traditional models, thereby leading to more realistic settlement predictions.Read moreRead less
A study of turbulence and influence of anthropogenic inputs in small subtropical estuaries. This project aims to improve our basic understanding of mixing and dispersion processes in small subtropical estuaries, and to develop improved predictive models to assist with the management of natural ecosystems. This will be the first comprehensive study of mixing processes and the influence of anthropogenic inputs in small subtropical estuaries.
The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, an ....The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, and so often expensive deviations have to be made to tunnels to avoid going near existing ones. The proposed research will provide numerical tools to allow prediction of loads induced into rock bolts by nearby tunnels, leading to more economical and safer tunnel design.
