Improving the security of anchoring systems under extreme cyclones. This project aims to investigate the behaviour of anchoring systems under cyclonic loading and to innovate anchor designs to improve their security during extreme cyclones.

This project aims to investigate the behaviour of anchoring systems under cyclonic loading and to innovate anchor designs to improve their security during extreme cyclones. Anchoring systems are increasingly playing the vital role of securing floating structures to extract ocean energies, but the current empirical knowledge and design method hinder confidence in engineering application. This project expects to advance the fundamental scientific understanding of the geotechnical mechanism of anchors under cyclonic loading using innovative experimental and advanced numerical modelling. Outcomes will include quality first-hand data contributing to the knowledge base, innovative anchor designs and new scientific based design guidelines.Read moreRead less

Summary
Design Waves: a new basis for safer and more efficient offshore systems. This project will overcome a fundamental issue at the heart of ocean engineering design, impacting our oil, gas and renewables industries. Ocean waves are random, yet the best design tools for wave-structure interaction (model testing and computational fluid dynamics) require short, precisely-defined wave sequences. This project will establish a paradigm shift, bridging this gap via a new unified Design Wave methodology dev ....Design Waves: a new basis for safer and more efficient offshore systems. This project will overcome a fundamental issue at the heart of ocean engineering design, impacting our oil, gas and renewables industries. Ocean waves are random, yet the best design tools for wave-structure interaction (model testing and computational fluid dynamics) require short, precisely-defined wave sequences. This project will establish a paradigm shift, bridging this gap via a new unified Design Wave methodology developed for a diverse set of offshore systems, each with different criticalities. The new methodology will fuse advanced techniques in fluid mechanics, statistics and applied maths. The outcomes will create reductions in uncertainty and improvements in design and safety for facilities such as wind farms and gas platforms.Read moreRead less
Anchoring the next generation of offshore floating infrastructure. This project aims to advance the fundamental scientific understanding of embedded anchor behaviour and to develop engineering solutions to secure the next generation of floating platforms, wind turbines and submerged tunnels. This is significant because limited understanding of anchors under long-term sustained and cyclic loading, and in how wave-chain-anchor systems behave, is hindering confident deployment in deep water and har ....Anchoring the next generation of offshore floating infrastructure. This project aims to advance the fundamental scientific understanding of embedded anchor behaviour and to develop engineering solutions to secure the next generation of floating platforms, wind turbines and submerged tunnels. This is significant because limited understanding of anchors under long-term sustained and cyclic loading, and in how wave-chain-anchor systems behave, is hindering confident deployment in deep water and harsh conditions. This project will address this challenge by combining precise observations from sophisticated physical and numerical experiments into an analysis framework that integrates system response. Outcomes will include numerical software, analytical tools and design charts for engineers to use in design.Read moreRead less
Lifting objects off the seabed. This project aims to investigate the process of lifting objects off the seabed. Understanding this breakout process is the scientific basis for a variety of offshore applications such as oil and gas decommissioning, marine salvage and securing foundations under extreme storms.

This project aims to investigate the process of lifting objects off the seabed. Understanding this breakout process is the scientific basis for a variety of offshore applications such as oil and gas decommissioning, marine salvage and securing foundations under extreme storms. This project expects to advance the understanding of soil-fluid-structure interactions of this problem using innovative high-speed photography observations and advanced numerical coupled analyses. Outcomes will include a numerical tool, verified against a high quality experimental database, to predict the breakout process and uplift required for pressing offshore challenges. The ability for Australia’s engineers to predict lift procedures more accurately will contribute to safer operations in Australian waters and to the more economic harnessing of ocean resources.Read moreRead less
