Harnessing the power of oceans: anchors for floating energy devices. This project aims to establish a geotechnical design framework for shared anchoring systems subjected to multidirectional cyclic loading for large integrated arrays of floating wind turbines and floating wave energy converters. This is expected to facilitate new, economic foundation solutions, generating radical cost savings to help unlock Australia's renewable ocean energy resources.

This project aims to establish a geotechnical design framework for shared anchoring systems subjected to multidirectional cyclic loading for large integrated arrays of floating wind turbines and floating wave energy converters. This is expected to facilitate new, economic foundation solutions, generating radical cost savings to help unlock Australia's renewable ocean energy resources. The project aims to utilise a blend of state-of-the-art centrifuge modelling techniques and numerical modelling, incorporating an energy-based method and yield envelopes. This innovative methodology aims to establish a validated framework for understanding and predicting foundation performance under the complex load histories arising in renewable ocean energy applications.Read moreRead less
New Silent Anchors for Floating Offshore Wind Turbines in Calcareous Sand . Reliable wind energy sites are in deeper waters and require offshore floating structures to harness the wind energy. Such floating structures require a reliable anchoring system that is secure and environmentally friendly. Calcareous sands, rich in carbonate content, pose unique challenges with their behaviour difficult to predict. In this project, a novel silent anchoring system is investigated that can be installed wit ....New Silent Anchors for Floating Offshore Wind Turbines in Calcareous Sand . Reliable wind energy sites are in deeper waters and require offshore floating structures to harness the wind energy. Such floating structures require a reliable anchoring system that is secure and environmentally friendly. Calcareous sands, rich in carbonate content, pose unique challenges with their behaviour difficult to predict. In this project, a novel silent anchoring system is investigated that can be installed with minimum noise and vibration compared to more traditional counterparts. Through the state of the art development in numerical modelling and centrifuge modelling, this project will advance Australian Science and Practice in designing floating wind turbines in carbonate rich soils offshore and help energy transition.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
