“…Recently, rectangular floating breakwater (RFB) and trapezoidal floating breakwater (TFB) have been broadly studied by some researchers (e.g. Liu and Wang 2020;Jeong and Lee 2014;Bin Abd Razak 2014;Hornack 2011;Masoudi and Zeraatgar (2017); Nikpour et al 2019). FBs are broadly used primarily because of their reduced cost, flexible installation requirements and ability to dissipate the wave energy without constraining under-water flow in areas with tidal variations (Dai et al 2018;Stuart 2018;Rafic and Pascal 2009).…”

This paper presents a two-dimensional simulation model for the idealisation of moored rectangular and trapezoidal floating breakwaters (FB) motions in regular and irregular waves. Fast-Fictitious Domain and Volume of Fluid methods are coupled to track-free surface effects and predict FB motions. Hydrodynamic performance is assessed by a machine learning method based on Cuckoo Search-Least Square Support Vector Machine model (CS-LSSVM). Results confirm that a suitable combination of the aspect ratio of an FB and her sidewall mooring angle could help attenuate incoming waves to a minimum height. It is concluded that moored trapezoidal FBs are more efficient than traditional rectangular designs and subject to further validation CS-LSSVM can be useful in terms of optimising the values of predicted wave transmission coefficients.
