The calculation of the added mass and damping of two dimensional ship sections, is based on the work of Ursell (1949), for a two-dimensional circular cylinder heaving in the free surface. The work of Bishop et al. (1978) has expanded the original approach to include conformal mapping techniques which may be used to map the ship’s section to a unit circle centred at the origin, and hence calculate the hydrodynamic coefficients of arbitrary ship sections. The work of Sutherland (1987) is also a useful starting point and rephrases the method of Bishop et al. (1977).
