Flexible Floating Breakwater

Performance of pile-restrained flexible floating breakwaters

“…A comprehensive review of the hydroelactic theories is presented in [40], and in each of the aforementioned studies regarding hydroelasticity the floating body is assumed to be free-floating (unrestrained). The effect of flexibility on floating breakwaters has been studied by Williams et al [41] for one compliant beam-like breakwater (idealized as 1-D beam of uniform flexural rigidity) using an appropriate Green function, and by Abul-Azm [42] using an eigenfunction approach; both of these researches use 2-D hydrodynamic analysis. Pile-restrained breakwaters have also been investigated with rigid body conditions.…”

Wave scattering by flexible porous vertical membrane barrier in a two-layer fluid

“…Sollitt et al (1986) examined a system composed of two buoyant flaps clamped at the sea bottom and coupled with weighted mooring lines. Lee and Chen (1990) and Williams et al (1991) considered the case of a flexible breakwater consisting of a beam anchored to the seabed and tensioned by a buoy at the surface. Explicit solutions using Euler beam theory were obtained by Lee and Chen (1990), whilst Williams et al (1991) used the boundary integral equation method to analyse the same problem.…”

Dynamic Behaviors of a Moored Floating Structure with Flexible Skirts

“…Williams, et al [9,10] carried out the effects of the various wave and structural parameters on the efficiency of the breakwater as a barrier to wave action. His work has also considered the dynamics of a flexible floating breakwater which extended the entire water depth, and the dynamics of a submerged compliant breakwater consisting of a flexible, beamlike structure anchored to the seabed and kept under tension by a small buoyancy chamber at the tip.…”
