EFFECT OF HEAVY WEATHER MANEUVERING ON THE WAVE-INDUCED VERTICAL BENDING MOMENTS IN SHIP STRUCTURES
Statistical data are collected to quantify the probability of occurrence of voluntary course changes in heavy weather and their dependence on significant wave height and ship heading. Decision rules are established about when and how to change course, based on an analysis of operational data and interviews with experienced shipmasters. A Monte Carlo simulation is performed to determine how an omnidirectional distribution of initial headings is changed by voluntary course changes for different significant wave heights. Finally, the effect of the nonuniform distribution of headings on the mean wave-induced vertical bending moment is calculated. It is shown that although heavy weather maneuvering eases ship motions, it can increase the wave-induced bending moments and thus increase the probability of structural failure.
