HEAVING OSCILLATIONS OF TWIN CYLINDERS IN A FREE SURFACE

This paper presents a solution of the two-dimensional potential problem associated with harmonic oscillations of a twin-hull body in a free surface. The body considered has two identical, rigidly connected, circular cylindrical hulls, semisubmerged, performing small vertical oscillations. Results of the added-mass and damping coefficients are presented as functions of the oscillation frequency. Data presented can be used as a guidance to estimate the hydrodynamic characteristics of catamarans.
