Stiffness of mooring lines and performance of floating breakwater in three dimensions

Performance of pile-restrained flexible floating breakwaters

“…Analytical solutions of the hydrodynamic problem are available for simple geometries and regular waves [14]. Loukogeorgaki et al [15] and Diamantoulaki et al [16] used a 3-D hydrodynamic model to investigate the performance of floating breakwaters. Recently, 3-D analysis for a V-shaped floating breakwater was used by Briggs et al [17], including hydroelasticity.…”

Wave attenuation and flow kinematics of an inclined thin plate acting as an alternative coastal protection structure

“…When we put all these pieces together it is clear that the influence of wave steepness is the dominant parameter compared to structural parameters (submergence degree and inclination angle) and its value essentially determines the level of the performance of the ITP. This fundamental process was also observed in floating breakwaters [9][10][11]. In physical sense, this means that for a given ITP configuration, the energy dissipation process due to the presence of ITP is heavily dependent on the incoming wave characteristics.…”

“…This behavior is quite common also for floating breakwaters and other types of pile supported breakwaters [9,10,18,20,21,24,26]. In addition, for a given length of mildly sloped cases of ITP (i.e.…”

“…Hence, its performance diminishes for the higher values of wave length. For floating breakwaters, a very similar wave transmission behavior with respect to wave length is commonly observed [9,10]. Indeed, many researchers indicated that the ratio of structure length to wave length, l/L, is a major parameter in determining the performance of such structures [11,12,26].…”

“…Likewise, submerged permeable structures, pile-supported emerged (surface-piercing) structures, and floating structures are also widely studied as a means of coastal protection [9][10][11][16][17][18]20,21]. Surface piercing inclined plates were studied numerically first by Parsons and Martin [15] and then pursued by Parsons and McIvor [16] who tried to develop a model for the emerged inclined plates with the assumption that inclination angle is very small.…”
