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
Asymmetric and nonlinear unsteady loads on high speed ferries. Large high speed catamarans are expanding their domain of application from coastal passenger routes to ocean freight and military service. This is shifting operability criteria from motions and passenger discomfort to structural load limitations in severe wave environments. This project investigates large wave structural load prediction. Large waves lead to strongly non-linear responses, invalidating many methods of analysis.

Large high speed catamarans are expanding their domain of application from coastal passenger routes to ocean freight and military service. This is shifting operability criteria from motions and passenger discomfort to structural load limitations in severe wave environments. This project investigates large wave structural load prediction. Large waves lead to strongly non-linear responses, invalidating many methods of analysis. Prediction of loads on the transverse structure is also not possible with many prediction methods. This project will develop and validate by experiment fully time domain computational methods for the prediction of asymmetric structural loads due to large wavesRead moreRead less

This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offering improvements in efficiency and fuel consumption. The aims of this project are to understand the physical mechanisms associated with composite propeller noise generation. The outcomes are intended to provide advanced numerical capabilities that will support the development of quieter marine propeller designs to improve defence capability and the acoustic environment for marine mammals.Read moreRead less

Modernising Sydney’s fleet of iconic passenger ferries is an integral part of the New South Wales Government’s long-term transport master plan. The project is intended to predict the waves produced by any proposed ferry operation, allowing changes to be made to minimise waves during early planning stages. The new method for predicting the complex wave phenomenon is designed to provide more comprehensive and accurate assessments than conventional technologies.Read moreRead less

The aim of this proposal is to accelerate research across a range of disciplines using high performance computing which is currently limited by the present available computing power. These disciplines include: mathematical modelling of magnetic resonance imaging, computational chemistry, engineering fluid dynamics, climate system modelling including atmosphere, ocean and ice sheet simulations. The University of Tasmania, the Antarctic CRC and Australian Antarctic Division are combining resources to share in a joint facility of much greater capability. The proposed new high performance computing facility will increase in the computational power (over a weighted average of our benchmarks) by 13, an 8 fold increase in memory, and a 10 fold increase in disk storage. This new facility will allow these research groups to maintain their internationally leading edge status in high performance computing.Read moreRead less
