Review of probabilistic methods of stability assessment
Abstract
Due to the active development of probabilistic approaches to stability normalization, there is a need to study and adapt them to existing practice. The article provides an overview of probabilistic methods of stability assessment and various schemes for constructing probabilistic stability criteria. The review of various physical models of behavior of a vessel exposed to various external effects during operation is carried out. The objective of the review was to determine the most optimal method of probabilistic stability assessment for rationing purposes. From the review, it can be seen that the probabilistic method of stability assessment should take into account many random factors, such as loading, ship speed, heading angle, sea state, the presence or absence of additional heeling effects, such as the impact from the jerk of the tow rope, cargo breakage during lifting operations, etc. It is also necessary to take into account the specific operating modes which are actual for certain types of ships. In conclusion, it is noted that it is possible to build stability standards based on probabilistic methods and the need to take into account the time spent in various operating conditions is noted.
