The basic understanding of the hydrodynamic behavior of a two-body system is important for a wide variety of offshore operations. For such a complex problem, numerical simulation can provide data that can in turn be used to retrieve key information concerning the response characteristics of such systems. While there have been much study done of two ship shape floating structures (of similar dimensions) side-by-side such as the offloading of oil and gas from one vessel to another, it can’t be said that the same amount of attention has been given to the hydrodynamic analysis of two side by side floating bodies where one vessel is significantly larger compare to the other vessel thus capable of generating significant shielding effect on the smaller vessel. Wave structure interaction; offshore structures; frequency domain; shielding effect; dynamic analysis. Parametric study is performed to understand this shielding effect on various spacing between the two vessels, different location and change in orientation of these two bodies as well. It has been found that the smaller barge receives significant amount of disturbance in its motion due to the presence of large barge near it. The results of these analyses will be helpful to further understand the physics of shielding for this combination of large and small vessel and will help to further investigate the nonlinear phenomena related to shielding.
