Prediction of oil outflow in the case of a ship-ship collision based on energy considerations

The work reported herein aims at the development of a methodology for the a ssessment of the behavior of tankers when involved in a ship-ship collision . It may be applied for the comparison of the behavior of tankers with diff erent tank arrangements and it further accounts for differences in the stru ctural configuration and scantlings. The proposed methodology is based, on the one hand, on the results of an analysis of damage cases expressed in te rms of oil outflow versus collision energy and, on the other hand, on the d istribution function of collision energy. These relationships are combined to obtain the distribution function of the oil outflow. The use of the meth odology to investigate the influence of a stringer plate in a double-hull t anker illustrates its applicability and potential.
