Conformal mapping techniques are used as a means of representing the two-dimensional ship section by means of an array of roughly 10 elements. Hence, the geometric properties of any transverse section are determined in an explicit form rather than by numerical approximation. The reverse procedure of generating ship sections from the mapping coefficients is discussed. The arbitrarily spaced transverse sections are integrated longitudinally to give specific values for volumes of tanks or damaged compartments, as well as the general ship volume characteristics for the case of level trim or any other mathematically defined waterline profile, such as a sinusoidal or trochoidal wave. This use of conformal mapping coefficients as ship geometry inputs is particularly suited for computer applications because of its compact storage requirements. It is identical to the input used for ship dynamics calculations to determine ship motions and loads in waves, vibrations, etc. Examples showing applications of this approach in both ship design and on-board hardware manipulations are given.
