Abstract: Paper The scope of the paper focuses on the “Investigation or say the study of Frequency Responses of a vessel under open sea conditions.” The area of interest is how to change in characteristics properties of the vessel or the design parameter of the berth effects the free motions of the vessel. This paper covers mathematical modelling of the motion equations and study of its application in the development of the Frequency Response Calculation (FRC) section of the software MIKE-21MA. The effects on added mass, Damping, Exciting forces and the responses amplitude operator due to these changes are studied. The effect of this parameter over the free-floating vessel in the case to understand which parameter effects which motion. As the trend of increasing trade between the countries using the water routes rather the inland or airways due of obvious drawbacks in terms of transport the demand of the new building of ports and harbours is now in great demand. It is not just the ports or harbours but at the same time the size of the vessel is also continuously increasing at the same rate. As we move further in the paper, it will be observed how the simple potential coefficient could help us understand the vessel properties.It leads to predefine if the constraints could be increased or decreased at the same time the availability of the suitable berth in terms of draft or environmental conditions to support in vessel motion constraint.
