Abstract

A linear slender-body theory of springing is derived. The wave excitation loads are calculated by a generalization of the short-wavelength theory of Faltinsen. A Green's function approach is used to find the pressure distribution. Numerical results are compared with experimental results of Wereldsma and Moeyes. The "forced-motion loads" are obtained by a generalization of the Ogilvie and Tuck approach for forced heave and pitch motions. Discrepancies with other methods are discussed. Numerical results of springing are presented.
