This project will reduce the cost of ocean wave energy, by uniting leading expertise from academia with cutting-edge know-how and full-scale data from industry to advance the way oceanic forces on wave energy converters are represented in industry models. These models are critical for designing and controlling the next generation of wave energy converters, which have larger motions than ever before. Carefully tested models will lead to better estimates of power production and loads, which will drive down the cost of wave energy and enable its large-scale utilisation. Broad communication of benefits and sharing of new knowledge will accelerate commercialisation of ocean energy in Australia and pave the way to meeting our future energy needs.Read moreRead less

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

The novel approach will make use of multiple decades of the background 'noise', recorded continuously by earthquake seismic observatories, to locate and analyse ocean storms through time and identify changes in storm tracks. An interdisciplinary interpretation will follow which combines the large body of new results from seismology with data from oceanography and meteorology. Significant advancement in our knowledge of severe storms will benefit Australia by indicating whether such storms are becoming more severe or, alternatively, if storm patterns are shifting.Read moreRead less
