Hydrodynamic studies of floating structures: Comparison of wave-structure interaction modelling

Current panel methods for wave-structure interactions employ the potential flow theory, which provide fast, reliable and relatively accurate predictions marine structures, now some open source packages, NEMOH HAMS, are available. In this research, relative utility performance of HAMS is compared with well-known, state-of-art software, WAMIT. To bring focus to these comparisons, research based on three different floating structures: truncated cylinder; cylinder heave plate; a novel multi-axis TALOS wave energy converter. make comparison more useful, investigates incomplete overlapped panels simple cylinder, examine whether respective code can handle still meaningful solution. The comparisons may help us understand and/or be used simplifying numerical modelling those very complicated structures. From it seen both could produce good results single structure, but also exhibit capacities in dealing Specifically, thin structures effectively as
