船体タンク内変動圧力の統計的予測(続) : 満載矩形タンク内流体圧の極大値分布

A method is proposed for calculations of the statistical distribution of the maxima of nonlinear ship response such as the hydrodynamic pressure induced on the full-filled prismatic tank walls. The application of this method is made for a large oil tanker in short-term sea waves. The calculated results of the statistical distribution of the maxima of the non-linear hydrodynamic pressure have been examined in comparison with histograms obtained from the numerical simulated histories of the non-linear one. Satisfactory agreement is found between both results and the validity of the proposed method is recognized. And, the short-term correlation coefficients between component ship accelerations are investigated to examine the utility of the proposed method.
