INFLUENCE OF DRAFT VARIATION ON HEAVE ADDED-MASS AND HYDRODYNAMIC DAMPING COEFFICIENTS OF FLOATING BODIES

A general nonlinear theory for solving the radiation problem for floating or immersed bodies in a periodic heave motion, composed of a number of harmonic components, is applied for calculating the influence of draft variations on the linear hydrodynamic coefficients for heave. It is shown that a calculation method for added-mass and damping coefficients of axisymmetric bodies based on a boundary integral equation method can easily be modified to also obtain numerical values of the first and second derivatives with respect to draft of the hydrodynamic coefficients. The method is illustrated by experimental and numerical data for a floating cone.
