STABILITY AND ROLLING OF A SHIP WITH SHIFTING CARGO

Investigation of stability and rolling of a ship with bulk cargo has been accomplished under the supposition that the internal friction angle of bulk media is a random value submitted to normal distribution law. At calculation of additional heeling moment due to displacement of cargo one uses the hypothesis that the surface of cargo remains flat and the angle of its inclination to the horizon does not exceed the angle of internal friction (angle of response). Characteristics of rolling in rough seas have been found by methods of static linearisation and multidimensional Markovian processes taking into account action of wind and additional moment due to cargo displacement. Estimation of probability of heavy loose bulk cargo caving has been accomplished by methods of the theory of random processes overshoots.
