The working environments for wave energy converter (WEC) and breakwater are strongly compatible. An integration of these two can improve the utilization of marine infrastructure and reduce the cost of power generation; meanwhile the energy extraction of WEC can attenuate more wave. This project proposes an integrated system of oscillating-water-column (OWC) converters and floating breakwater (FB) and intends to investigate the hydrodynamic performance of the integrated system through a combination of theoretical analysis, physical experiment and numerical simulation. The theoretical analysis and hydrodynamic experiment will be employed to study the characteristics of wave response. The particle image velocimetry experiment and viscous flow numerical simulation will be employed to study the characteristics of surrounding flow field. Through a comprehensive analysis of the characteristics of both wave response and surrounding flow field, the essential relationship between flow field pattern and wave energy dissipation is explored, and its influential mechanism on both energy extraction and wave protection is to clarify. The interaction law among FB carrier-OWCs-mooring system is further delved into to reveal the matching optimization criterion, thus the scientific criteria for the practical operation of the integrated system in terms of high efficiency and low cost can be provided. Enhancement on the extraction of long waves through the design of resonance period and damping characteristic of OWCs is explored to improve the attenuation of long waves by the integrated system, which can break through the existing application bottleneck of FBs. While using environmentally friendly FBs for efficient protection against wave, we can sufficiently utilize wave energy to provide sustainable clean energy for offshore facilities. This project is of great significance and wide application value.
