Influence of relative draft on transmission characteristics of floating pipe breakwater with relative spacing of three
The paper presents the results of model scale experiments for the study of the transmission characteristics of
horizontal interlaced, multi-layer, moored floating pipe breakwater (HIMMFPB). The studies are conducted with
breakwater models having three and five layers of pipes, W/L (W is width of breakwater) varying from 0.4 to 2.65,
relative draft varying from 0.16 to 0.36 and relative spacing S/D = 3 (S is spacing of pipes and D is diameter of
pipe). The transmitted wave height is measured and analyzed by plotting non-dimensional graphs depicting the
variation of Kt (transmission coefficient) with relative width, W/L for different values of relative draft, Df/d(Df is
draft of breakwater and d is depth of water). It is observed that Kt decreases as W/L increases and it is also observed
that as Df/d increases Kt value decreases for the range of experimental values considered in the experiments.
