The Natural Frequencies for the vessel have been computed iteratively by solving a system of matrices. These matrices describe the mass and the stiffness of the vessel. This is the generalized eigenvalue/ eigenvector problem and is referenced in some mathematical texts. The Natural Frequency for the Vessel (Empty.) is 14.5521 Hz. The Natural Frequency for the Vessel (Ope...) is 14.3855 Hz. PVElite 5.0, 2003 ©1993-2003 by COADE Engineering Software
