ANALYSIS OF BARGE MOTION USING STRIP AND THREE DIMENSIONAL THEORIES

Three-dimensional response theory has been developed into a computer model that can be applied to both slender and barge-like objects. The objectives of this study were to: (1) utilize both of these theories to analyze, in a systematic manner, box-like shapes for various drafts, periods of excitation and length-to-beam ratios (L/B); and (2) compare results as calculated from each theory. These results were for head-on seas only. Comparisons are based on the response amplitude operators of heave, surge, and pitch as a function of L/B which ranged from 1.0 to 8.0. For the case of the pitch response operators, at L/B = 8.0, shallow draft results were within 22% of each other; the deep draft comparison was within 45%. Predicted response for heave showed less than 30% difference for both the shallow and deep draft floating boxes. This study is also pertinent to the mooring of ships and buoys.
