This project will solve important problems in realising next generation underwater optical fibre sensor systems for defence and marine exploration. OFTC's expertise in specialty optical fibre and devices will be combined with Thales' expertise in underwater sensor systems to give Australia a global lead. The benefits are commercial, national security and research standing. Domestic manufacture of a major optical system will assist maturation of the sector which is dominated by component companies. This system for underwater surveillance is obviously important to a country with a large coastline to defend. This project will build Australia's global reputation renowned for research excellence in fibre and fibre devices.Read moreRead less
The Legal Framework for International Cooperation in Maritime Enforcement Activities. The Project will analyse the gaps in the international framework to achieve cooperation in maritime enforcement and make recommendations for improvements to existing legislative arrangements to facilitate successful combat of international maritime criminal activity.The Project is timely because it addresses some long-standing national requirements to improve Australia's ability to adequately enforce its sovere ....The Legal Framework for International Cooperation in Maritime Enforcement Activities. The Project will analyse the gaps in the international framework to achieve cooperation in maritime enforcement and make recommendations for improvements to existing legislative arrangements to facilitate successful combat of international maritime criminal activity.The Project is timely because it addresses some long-standing national requirements to improve Australia's ability to adequately enforce its sovereign rights throughout its maritime zones of jurisdiction. The issues involved have taken on a greater contemporary significance in light of recent events, including the surge in illegal people smuggling into Australia, increased illegal fishing activity in Australia's Southern Ocean exclusive economic zone by highly organized criminal syndicates and heightened tensions with regard to maritime terrorism.

Understanding and predicting submarine hydrofoil noise. Australia needs to develop a more sophisticated underwater flow-induced noise research and development capability if it is to achieve its ambitious naval plans set out under the Defence White Paper. This project will develop an experimentally validated model to predict submarine noise for the purposes of submarine design, operation and procurement.
Optimal acoustic design of a composite marine propeller for signature management. Noise of maritime vessels affects passengers, crew and marine life. Composite marine propellers provide significant benefits over metallic propellers as they run more efficiently, thus consuming less fuel and run more smoothly, resulting in improved comfort for passengers and crew. From a military perspective, composite marine propellers provide reduced noise signature, resulting in vessels of greater stealth. Quie ....Optimal acoustic design of a composite marine propeller for signature management. Noise of maritime vessels affects passengers, crew and marine life. Composite marine propellers provide significant benefits over metallic propellers as they run more efficiently, thus consuming less fuel and run more smoothly, resulting in improved comfort for passengers and crew. From a military perspective, composite marine propellers provide reduced noise signature, resulting in vessels of greater stealth. Quieter propellers also significantly reduce the environmental impact of ships on marine life. This project will generate a new class of quiet composite propellers to be utilised by the maritime industry. The technologies developed by this project are applicable to rotors in other industries, such as aircraft, helicopters and wind turbines.Read moreRead less
Wave slam on high speed wave piercing catamaran ferries in large seas. Australia has taken a pioneering lead in the design of high speed multi-hull ferries and continues to extend their speed, range and payload performance. Design leadership and the technology which supports it are crucial to maintaining the existing large share of the international market for such vessels. Recently freight and military transport vessels have been exposed to much more severe wave conditions than passenger vessel ....Wave slam on high speed wave piercing catamaran ferries in large seas. Australia has taken a pioneering lead in the design of high speed multi-hull ferries and continues to extend their speed, range and payload performance. Design leadership and the technology which supports it are crucial to maintaining the existing large share of the international market for such vessels. Recently freight and military transport vessels have been exposed to much more severe wave conditions than passenger vessels and this has increased the need for improved prediction of structural loads due to waves. This project directly addresses that need by computation and model testing validation. The industry is a significant export earner and employer within Australia and so the project directly underpins those national benefits. Read moreRead less
Automated helicopter hover and recovery system for operations at sea. The small size and simplicity of the integrated system outlined in this project will significantly improve the effectiveness of maritime surveillance for homeland security whilst enabling substantially lower operational costs. The proposal aims to develop control and sensing techniques, enabling small rotary wing unmanned air-vehicles (UAVs) weighing less than 100 kgs to operate from small-size vessels. This will be achieved ....Automated helicopter hover and recovery system for operations at sea. The small size and simplicity of the integrated system outlined in this project will significantly improve the effectiveness of maritime surveillance for homeland security whilst enabling substantially lower operational costs. The proposal aims to develop control and sensing techniques, enabling small rotary wing unmanned air-vehicles (UAVs) weighing less than 100 kgs to operate from small-size vessels. This will be achieved by resolving the current lack of integration between ship motion and the unmanned vehicle guidance systems. The proposed research will make substantial contributions in areas of ship motion prediction and sensing and hover control of tethered and non-tethered small helicopters.

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
