ACTIVE CONTROL OF SURFACE OCEAN SHIPS. This research is to design nonlinear robust adaptive control systems using active actuators (flaps, fins and rudders) for course keeping and path tracking of surface ocean ships, which are inherently nonlinear and with uncertainties. The outcome of the research will lead to the development of non-linear control strategies, which result in simple-to-implement and effective controllers. These controllers are robust to the environmental disturbances and uncert ....ACTIVE CONTROL OF SURFACE OCEAN SHIPS. This research is to design nonlinear robust adaptive control systems using active actuators (flaps, fins and rudders) for course keeping and path tracking of surface ocean ships, which are inherently nonlinear and with uncertainties. The outcome of the research will lead to the development of non-linear control strategies, which result in simple-to-implement and effective controllers. These controllers are robust to the environmental disturbances and uncertainties, adapt to unknown parameters of the ship and actuators. Only a few control gains are required to be tuned. The success of this project will significantly increase the international competiveness of Australian shipbuilding industry.Read moreRead less

Summary
Optimising bioengineered structures for resilient shorelines and habitats. Nature-based solutions for shoreline protection through ecosystem restoration are increasingly being considered by foreshore managers. However, habitat restoration efforts are greatly hampered by the time it takes to fully revegetate an area. This project aims to develop a comprehensive understanding of wave interaction with bioengineered structures that provide shelter from wave impacts and promote revegetation and contr ....Optimising bioengineered structures for resilient shorelines and habitats. Nature-based solutions for shoreline protection through ecosystem restoration are increasingly being considered by foreshore managers. However, habitat restoration efforts are greatly hampered by the time it takes to fully revegetate an area. This project aims to develop a comprehensive understanding of wave interaction with bioengineered structures that provide shelter from wave impacts and promote revegetation and contribute to shoreline flood and erosion mitigation. Expected outcomes of this project include quantitative design guidelines and predictive tools that will help foreshore managers to develop more robust and cost-effective nature-based shoreline protection strategies.

The expected outcomes include enhanced capacity to estimate hydrodynamic response and advanced design tools for floating wind, floating solar and offshore aquaculture. This will provide significant benefit by enabling cost-efficient and viable designs, thereby accelerating the development of offshore renewable energy.Read moreRead less
Australian coastal observation network: monitoring and forecasting coastal erosion in a changing climate. Australia's coastline is one of this country's greatest natural, economic and cultural resources. The asset value of existing beach-front infrastructure is immeasurable. Climate change is driving sea-level rise and changing regional wave climates, resulting in coastal erosion and increasing the threat to coastal sustainability. This research launches a strategic university-industry-governmen ....Australian coastal observation network: monitoring and forecasting coastal erosion in a changing climate. Australia's coastline is one of this country's greatest natural, economic and cultural resources. The asset value of existing beach-front infrastructure is immeasurable. Climate change is driving sea-level rise and changing regional wave climates, resulting in coastal erosion and increasing the threat to coastal sustainability. This research launches a strategic university-industry-government alliance to address the considerable and growing pressure for solutions to observe and forecast accelerating shoreline erosion. The new knowledge, greater cross-sector collaboration and international linkages to be fast-tracked by this project will inform and build the capacity of Australia's coastal managers to confront the challenges of a changing climate.Read moreRead less
Numerical Modelling of Three-dimensional Scour below Offshore Pipelines. Australia's increasing offshore oil and gas exploration has demanded more accurate and reliable methods for evaluating the safety and serviceability of pipelines. Local scour around pipelines is one of the major causes of pipeline failures, and is a major concern in Australian waters. This project not only addresses these concerns in its direct application to the design and management of offshore pipelines, but also will co ....Numerical Modelling of Three-dimensional Scour below Offshore Pipelines. Australia's increasing offshore oil and gas exploration has demanded more accurate and reliable methods for evaluating the safety and serviceability of pipelines. Local scour around pipelines is one of the major causes of pipeline failures, and is a major concern in Australian waters. This project not only addresses these concerns in its direct application to the design and management of offshore pipelines, but also will contribute to the nation's development and competitiveness in offshore exploration, and produce high quality research students. The improved design and management of pipelines in Australian waters will reduce the risk of potential environmental damages caused by leaking gas and oil.Read moreRead less
Engineering solutions for the next generation of offshore oil and gas infrastructure. Offshore extraction of oil and gas reserves is a key industry for Australia, annually contributing A$21 billion to the economy, and underpinning much of our prosperity. With reserves close to shore being exhausted and A$1 trillion of gas reserves (four times that already developed) known to be 'stranded' in deep and remote locations, the outcomes of the proposed research programme will help scientifically under ....Engineering solutions for the next generation of offshore oil and gas infrastructure.
