内容摘要：
Multi-body interactions are key to design of offshore infrastructure, from oil & gas platforms to rapidly growing renewable energy devices. Due to the close proximity, strong resonant responses of the water (the gap resonance) between multiple bodies may occur. The responses at resonance are of particular interest, where damping and nonlinearities play significant role. This talk will present some interesting physics associated with resonant responses that are associated with multi-body interactions.
Industry applications will be covered in this talk, to show how fundamental studies can be adopted to impact engineering practice. This talk will also show how to publish quality papers in leading journals.

内容摘要：
Floating offshore wind energy is poised to be the next frontier in marine renewable energy, unlocking the immense potential of marine resources. It is essential to accurately predict the responses of floating wind turbines. Potential flow calculations seem to deviate from experimental studies, particularly under severe sea states where viscosity plays a significant role. Focusing on a semi-submersible type of floating wind turbine, a series of experiments in a wave basin have been re-analysed using novel data analysis techniques. Interesting and new phenomena are observed and will be introduced in this presentation. Viscosity is found to affect both the response amplitude (via damping) and the natural frequency (via extra added mass) – way beyond the damping effect in a damped spring system.
