Powering optimisation of large, energy-efficient multihull vessels, operating at critical speeds. Australia is currently the world leader in the design and construction of large aluminium vessels. The existing fleet of vessels is under pressure from increased fuel prices and regulatory requirements to reduce emissions; this project directly addresses the need to develop new energy-efficient multihull vessels using computations and model testing.
The influence of sway-roll coupling on the dynamics of an inverted sailing yacht in waves. The ability of a sailing yacht to re-right in waves after capsize will influence the safety of those on board in extreme conditions.
The aim of this project is to incorporate the effects of sway-roll coupling into a numerical simulation of the behaviour of an inverted yacht in waves to assess design features which influence re-righting. Experimental work being conducted during 2001 will be extended to ....The influence of sway-roll coupling on the dynamics of an inverted sailing yacht in waves.

This project aims to develop a monitoring system to remotely measure ship motions, loads and ride control activity under commercial operations. Data will be analysed using advanced statistical methods to inform evidence-based design to improve both structural efficiency and passenger comfort. The research will impact on design rules used worldwide, reducing weight and increasing payload and transport efficiency for this class of vessel. A "Smart” semi-autonomous interface will be developed to provide on-board seakeeping guidance to the ship captain. This technology will have significant benefits such as increased ship safety, vessel longevity and improving passenger comfort for all types of vessels worldwide including high-speed catamarans.Read moreRead less
Marine vessel wave wake: Ferry operations in sheltered waterways. This project aims to address one of the biggest risk factors to the Sydney ferry system, by ensuring the waves that new ferries generate are minimised. This would reduce the impact on other users of this busy waterway or damage to the surrounding infrastructure or environment. 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 ....Marine vessel wave wake: Ferry operations in sheltered waterways. This project aims to address one of the biggest risk factors to the Sydney ferry system, by ensuring the waves that new ferries generate are minimised. This would reduce the impact on other users of this busy waterway or damage to the surrounding infrastructure or environment. 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

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.

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
