TL;DR: In this article, the wave-attenuation performances and hydrodynamics of moored box-type floating breakwaters with the same weight, same wall thickness, and six different cross-sections, i.e. circular, triangle-down, triangle up, rectangular, trapezoid-down and trapezoidal-up, are investigated numerically using the smoothed particle hydrodynamic (SPH) method.

Experimental study on hydrodynamic characteristics of a new type floating breakwater with opening pass and wing structure
TL;DR: In this paper , a new type of floating breakwater with an opening pass is proposed to attenuate long-period waves better, and a series of experiments, including a traditional dual-box FB and five new type FB models with different outlet radii, were carried out to investigate and compare the hydrodynamic performance.

Experimental investigation on the wave-attenuating performance and shape optimization of water ballast type floating breakwater
TL;DR: In this paper , two different connection modes (catenary type and tensely type) of water ballast Box-type FB is experimentally investigated, and the results show that when compared with tensely Type, the mooring force of catenary type is significantly reduced while maintaining similar wave-attenuating performance, indicating its suitability for engineering.

An experimental study of a floating breakwater with asymmetric pneumatic chambers for wave energy extraction
TL;DR: In this article, a configuration of floating breakwater with asymmetric pneumatic chambers was proposed to increase the amplitude of the oscillating air-pressures inside both chambers over a wide range of wave frequency (thus to improve the performance in wave energy extraction).

Radiation and scattering of water waves by rigid bodies
TL;DR: Schwinger's variational formulation is applied to the radiation of surface waves due to small oscillation of bodies in this paper, where the wave forces on a stationary body due to a plane incident wave are found using only far-field properties.

Mooring forces and motion responses of pontoon-type floating breakwaters
TL;DR: In this article, a two-dimensional finite element model is adopted to study the behavior of pontoon-type floating breakwaters in beam waves, and the stiffness coefficients of the slack mooring lines are idealized as the linear stiffness coefficients, which can be derived from the basic catenary equations of the cable.
