In this paper, a calculation method of hydrody namic. coefficients of two-dimensional ship sections for heave and sway motions, in cases of deep wa ter and zero-fonvard speed, are discussed . In this method, seetions ean be in different geometrical shapes. For this purpose, a potential solution with multi pole expansion aitd two-paraineter Lewis con formal mapping, has been used. Using this method, a code is developed that is capable of calculating added-mass and dainping coefficients of cross - see tions. Also, the results of the code for circular, tri angular and rectangu lar sections are in good agree ment with experiments . Therefore, the developed code can be used for hydrodynam ic calculations of ships with any arbitrary hull form.
