This paper aims to present the effect of dynamic motion interaction between Round Shape FLNG and KVLCC2 to the RAO of the Round Shape FLNG. The research focuses on the effect of radiation waves generated from the motion of the floating structures and the propagated radiation wave outward to nearby influenced structures. To conduct this study, the Round Shape FLNG and KVLCC2 were arranged in parallel head-sea arrangement to capture the strong radiation wave effect on the RAO of Round Shape FLNG. The proposed method was developed to estimate the RAO of Round Shape FLNG due to the radiation wave generated by the motion of nearby structures. Using this method, the wave force and hydrodynamic coefficient were calculated based on the diffraction potential theory and modified drag term of Morison. In addition, the dynamic motion interaction effect was estimated based on the Motion Dissipate Energy concept and Huygens Principle. To verify the proposed method, motion experiments in regular waves were conducted in selected conditions. Then, the results predicted by the proposed method were compared to the experiment results. The comparison showed that the RAO tendency of the Round Shape FLNG in 6 DOF estimated by the proposed method agrees with the results from the experimental test. Hence, this study concludes that the effect of the radiation wave generated by the motion of floating structure is an important factor in the study of motion interaction among the floating structures.
