The UK is looking into the development and use of renewable energies to reduce carbon emission to mitigate its adverse impact on global warming and climate change. Offshore wind provides the most promising ecofriendly green energy that could help to achieve the low carbon emission target in the near future and support the long‐term sustainable development of the UK. With the coming saturation of near‐shore wind turbines, the industry is currently moving towards the designing and deploying large floating turbines into the deep sea to harness overwhelming wind energy.
To support the development of large‐scale offshore floating wind farms, advanced engineering modelling of the wave‐structure interaction is a necessity to assess the survivability of turbines subjected to high sea states and to improve their efficiency. It requests well‐balanced multi‐scale calculation of large areas (miles by miles) of incoming and scattering waves and small regions (inches by inches) of flows around the structure.
This project will develop a powerful unified hydrodynamic modelling framework for offshore floating structures. This new generation tool will surpass the currently available individual or coupled wave hydro‐codes to perform fast and accurate calculation of realistic multi‐scale problems. This will enable the research and industry communities to carry out timely systematic analysis of the performance and survivability of offshore structures especially the renewable energy devices deployed in deep sea subjected to high wind and large waves. This will also empower engineers to explore a much broader regime where heuristic methods could be used to optimise the design of offshore structures, which currently is not affordable due to the limited time and computing resources.
This project aims to: *Develop a stable single‐phase finite volume based potential flow code for wave hydrodynamics. *Develop an accurate method to link the potential flow code with Navier‐Stokes codes. *Develop an effective strategy to carry out parallel computation using the unified numerical modelling framework. *Validate the developed numerical tool and assess its accuracy and efficiency. *Investigate extreme hydrodynamic loads on an offshore floating wind turbine under high‐sea states.
