Experimental Study of the Effects of Different Floating Breakwater on Wave Absorbing

As the development of ocean engineering, safety construction is becoming a significant aspect that attracted more and more attention. The general aims of this paper were to present the effects of different floating breakwater on wave absorbing and provide a basis for the design of floating breakwater of an offshore project. Three different kinds of floating breakwater were studied; they are soft wall-sided pontoon, solid wall-sided pontoon and a circular cross-section breakwater filled with water. Various factors including wave period, wave steepness and geometrical characteristics were considered. The results had shown that the three proposed floating breakwater revealed favorable performance and the geometrical configuration could impact wave attenuation significantly. The circular cross-section breakwater had greater effects on wave absorbing compared with two other floating breakwaters, more detailed experiments were conducted to the circular cross-section breakwater, a V-shaped floating breakwater consists of two single circular cross-section breakwater were studied, the effects of angle of the two singles, wave period and wave height were considered. The results revealed that the geometrical configuration and water depth could impact wave attenuation and mooring force significantly. Researches are expected to offer some information for the design of floating breakwater for an offshore project.
