Performance Characteristics of Horizontal Interlaced Multilayer Moored Floating Pipe Breakwater

Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 133, Issue 4

Abstract

The paper presents the results of model scale experiments for the study of wave attenuation by horizontal interlaced, multilayer, moored floating pipe breakwater. A review of some significant floating breakwater models proposed by earlier investigators is included. For a floating breakwater the transmission coefficient (Kt) is influenced by relative width of the breakwater (WL) . Nondimensional graphs indicating the variation of Kt with respect to WL (with HiL as a parameter for different Hid values) and Kt versus HiL (for a range of dL values from 0.09 to 0.24) have been plotted. Further variation of Kt with relative depth dL for different WL values is also studied. From the experimental study and results obtained, it is found that the transmission coefficient decreases with an increase in relative breakwater width WL and wave steepness HiL for all Hid values. In the present study it was observed that performance was better for breakwater configurations of WL0.7 when compared with configurations of WL<0.7 . Further, the experimental results obtained were compared with the output of a mathematical model. From the comparison for HiL=0.04 , values of Kt obtained from the present experiments were in agreement with those obtained from the mathematical model.
