Some Calculation of Hyadrodynamic Forces on Semi : Submersible Bodies by Singularity Distribution Method

Abstract

Added masses, damping coefficients and wave forces on semisubmersible bodies are calculated by making use of singularity distribution method following Faltinsen and Michelsen The accuracies of the results of wave forces are examined by comparing the values of the diffraction problem with those of the radiation problem from Haskind relation. Total added masses, damping coefficients and wave forces estimated from the simple addition of those of elementary bodies are compared with those calculated as total bodies. In some range of wave number, there seem to be considerable differences between these two values.
