ABSTRACT Present study aims to investigate the influence of relative breakwater width W/L (W=width of breakwater, L=wavelength), wave steepness $ H_{i} $/$ gT^{2} $ ($ H_{i} $=incident wave height, T=wave period) and relative wave height d/W (d=water depth) on forces in the moorings of horizontal interlaced multi-layered moored floating pipe breakwater (HIMMFPB) model. Studies were conducted on scaled down physical models having three layers of Poly Vinyl Chloride (PVC) pipes, wave steepness $ H_{i} $/$ gT^{2} $ varying from 0.063 to 0.849, relative width W/L varying from 0.4 to 2.65 and relative spacing S/D=2 (S=horizontal centre-to-centre spacing of pipes, D=diameter of pipes). Peak mooring forces were also measured and data collected is analyzed by plotting non-dimensional graphs depicting variation of $ f_{s} $/$ γW^{2} $ ($ f_{s} $=Sea side Mooring force, γ=specific weight of water) & $ f_{l} $/$ γW^{2} $ ($ f_{l} $=Lee side Mooring force) with $ H_{i} $/$ gT^{2} $ for d/W varying from 0.082 to 0.276 and also variation of $ f_{s} $/$ γW^{2} $ and $ f_{l} $/$ γW^{2} $ with W/L for $ H_{i} $/d varying from 0.06 to 0.400.
