Abstract

This seminar will present an overview of wave-current-structure interaction problems for space-frame offshore structures. When a steady (current) flow encounters such a structure, the structure behaves as an obstacle array which provides resistance to the flow. Hence, there is a reduction in the effective flow velocity (compared to the free-stream flow velocity) and the associated hydrodynamic force on that structure, and this is termed current blockage. The seminar will present the analytical and numerical modelling of the additional blockage effects due to the presence of ocean waves, as well as structural dynamics, covering a wide range of applications of fluid loading on statically- and dynamically-responding offshore structures.

Biography

Dr. H. Santo returned to National University of Singapore (NUS) as a research fellow in May 2016. He is now working on modelling plunging breaking waves using Smoothed Particle Hydrodynamics (SPH), and co-supervising on wave-current-structure blockage and wave-in-deck project awarded by Singapore Maritime Institute to NUS, which is a continuation of his PhD topic. He obtained his PhD on wave-current blockage in offshore engineering from NUS in 2014. Subsequently, he continued to work as a postdoctoral research assistant in University of Oxford on wave climate variability and other research topics related to marine renewable energy funded by UK Engineering & Physical Sciences Research Council (EPSRC). His research interest is in fluid-structure interaction, wave statistics, and air-sea interaction.
