In an attempt to obtain a 2D floating breakwater model with high performance in wave reflection, geneticudalgorithm (GA) was combined with boundary element method (BEM) in the previous study. Theudperformance of the obtained model was verified with numerical relations as well as an experiment inudtowing tank. Moreover, its performance and characteristics in 3D case were also evaluated in theudsubsequent study. However, because the 3D model is formed by simply extruding the 2D shape inudlongitudinal direction, it only produces a model with uniform transversal shape which is considered to beudless effective and efficient in terms of technical and economical points of view. Consequently, it is neededudto modify the model to obtain a more realistic and efficient design without reducing significantly the highudperformance obtained previously. In the present study, several modifications of the original 3D model areudperformed which include placing moonpools inside the body. The performance and characteristics of theudmodified models in terms of wave elevations on the free surface are evaluated at various wavelengths byudusing higher order boundary element method (HOBEM). The accuracy of the computed results isudconfirmed with Haskind-Newman and energy conservation relations. From the modifications andudevaluations of the models, it could be realized that the moonpools inside the body could be used to obtainuda more realistic model without reducing the optimum performance of the original model shape.
