**About the Editors**

**Jaw-Fang Lee** is currently a research professor at Tainan Hydraulics Laboratory, National Cheng Kung University. He retired as a Professor from the Department of Hydraulic and Ocean Engineering, NCKU, 2020. He published four books (in Chinese): Fundamental Coastal Hydraulics, Finite Element Method, Boundary Element Method, and Wave Hydrodynamics of Ocean Structures. He has devoted to promoting the academic field of Coastal and Ocean Engineering in Taiwan.

**Ray-Yeng Yang** go<sup>t</sup> his Ph.D. degree from Institute of Naval Architecture and Ocean Engineering, National Taiwan University, Taiwan, in 1995. Right now he is an Associate Professor of Department of Hydraulic and Ocean Engineering, National Cheng Kung University (NCKU), Taiwan. He was research fellow and the former deputy director of Tainan Hydraulics Laboratory, NCKU (2015–2017). Now, he is also the executive director of Taiwan Society of Ocean Engineering and deputy secretary-general of Chinese Ocean & Underwater Technology Association. He has his expertise in ocean (coastal) engineering, ocean energy (wave & ocean current energy), ocean environment science (internal wave & Langmuir circulation), hydrodynamic stability (double diffusion, salt-finger convection), floating offshore structure (offshore wind turbine & marine aquaculture cage net) and physical modeling simulation. Until now, more than 250 (55 SCI, 40 EI papers & 160 conference) papers, two book chapters and 92 technical research reports have been published by Dr. Yang. For the latest years, his academic work has been published in international renowned, scholarly journals including "Journal of Fluid Mechanics", "Journal of Mechanics", "Geophysical Research Letter", "IJOPE", "European Journal of Fluid Mechanics-B/Fluid", "Acta Astronautica", "Ocean and Coastal Management", "The Open Ocean Engineering Journal", "Journal of Ocean and Coastal Engineering", "Physics of Wave Phenomena" , "Pure and Applied Geophysics" "Pure and Applied Geophysics", "IEEE-Ocean", "Journal Marine Science and Engineering", and "Ocean Engineering" etc.

#### **Preface to "Waves and Ocean Structures"**

It is interesting to know that the cease of the Journal of Coastal and Ocean Engineering in Taiwan has caused the inauguration of this special issue. The gues<sup>t</sup> editor thought this special issue might be a good alternative for interested authors to submit their masterpieces. Nevertheless, the guest-editors have their particular major research fields, and the rise of the topic "Ocean Waves and Structures." This is the first attempt of the guest-editors, and they also welcome related subjects to be submitted to this special issue. The guest-editors appreciate very much all contributors to this special issue. This special issue contains articles related to the main subjects, namely, ocean deployments that subjected to actions of ocean waves, and require research investigations studying mechanisms of wave actions. We hope the related research results will also continue to submit to this special issue. Thanks are also given to all assistant editors, without their help it would be impossible for the special issue to run in order and in effective ways to be published. Further, because the number of articles in this special issue has reached the milestone, and the special issue can be published as a book. This is also a prize for all authors and the guest-editors: Jaw-Fang Lee and Ray-Yeng Yang. The guest-editors also like to mention that this special issue will be extended to the next year with "Ocean and Waves and Structures II" as the topic. We hope all of us could work hard consistently to have a second continuous success.
