Abstract:

This study acquires the attitudes of floating bodies with irregular configurations using a computational model, that has been theoretically verified and can confirms these values by experiment. First, a simple correlation is described to predict inclinations for floating slender bodies where the lateral bias of the center of gravity is negligible. Then a computational model is employed to account for bodies with attitudes in more general situations. In addition, a case similar to a submarine is simulated to reveal that the inclinations vary abruptly around certain longitudinal locations of center of gravity. The property variations during water ingress are also presented numerically. Finally, the computational model is used to build a numerical data bank of properties for a specific floating body, by which the position of its center of gravity can be obtained by interpolation from known attitudes in the data tables.
