Novel wave energy foundation solutions to survive extreme loads. This project aims to develop an economic and efficient anchoring system for taut-moored wave energy converters to enable us to exploit sustainable wave energy resources. Australia’s potential near-shore wave energy resource is four times larger than the current total capacity of our installed power generation.

This project aims to develop an economic and efficient anchoring system for taut-moored wave energy converters to enable us to exploit sustainable wave energy resources. Australia’s potential near-shore wave energy resource is four times larger than the current total capacity of our installed power generation. But the development of ocean wave energy is presently hampered by expensive, traditional anchoring systems. Using better estimation of extreme loads, the project will use multidisciplinary approaches to investigate unique anchoring concepts with the aim of developing novel strategies to avoid the most extreme loads and enabling optimum anchor design. The outcomes of the project are intended to help to deliver economically viable wave energy projects.Read moreRead less

Summary
Unlocking the changing strength of fine-grained soils in numerical analyses. This project aims to numerically simulate strain-softening-hardening in fine-grained soils. Fine-grained soils soften during deformation and harden as excess pore pressures dissipate. Models exist that allow strain-softening and hardening in finite element simulations, but suffer from mesh-dependency. Regularisation methods can alleviate mesh-dependency, but an appropriate characteristic length for the regularisation is ....Unlocking the changing strength of fine-grained soils in numerical analyses. This project aims to numerically simulate strain-softening-hardening in fine-grained soils. Fine-grained soils soften during deformation and harden as excess pore pressures dissipate. Models exist that allow strain-softening and hardening in finite element simulations, but suffer from mesh-dependency. Regularisation methods can alleviate mesh-dependency, but an appropriate characteristic length for the regularisation is needed and difficult to determine. This project will use image-based soil deformation measurement and aspects of the finite element method to determine appropriate regularisation techniques, characteristic lengths and constitutive relations. Reliably modelling strain-softening and hardening in finite element simulations is expected to reduce uncertainty in design and make civil infrastructure cheaper.Read moreRead less

This promising alternative to impact-driven piles offers faster installation and requires no noise mitigation. The project expects to generate new knowledge of the effect of the installation process in sand on in-service pile response by integrating findings from innovative experiments and numerical modelling. This is particularly important for highly sensitive structures such as offshore wind turbines, which provide a rapidly increasing share of global energy supply. Expected outcomes include practical recommendations for vibro-piles in sand. This should provide sizeable benefits by unlocking vibro-piles as a viable method to reduce offshore wind farm costs.Read moreRead less

Crusty Seabeds: From (Bio-)Genesis To Reliable Offshore Design. The project aims to make deep water oil and gas developments safer and cheaper by understanding better the unique seabed ‘crust’ conditions that occur in Australian waters. By studying the biogenic, structural and mechanical properties of deepwater crusts in more detail than can be done in ‘live’ oil and gas projects, this project expects to make a step change in the understanding of these seabed crusts.
