Abstract

This article discusses the problem of mathematical modeling of the dynamics of a semi-submersible floating crane when positioning in work sites. The principles of constructing a mathematical model, input and determinable parameters, as well as the influence of external forces such as wind, current and waves on the dynamics of the crane are described. The use of a mathematical model of the dynamics of an underwater lifting device for modeling the movement of a crane is considered, and a functional block diagram of the DYNAMIC-PPBU program for analyzing the dynamics of a vessel in various storm conditions is presented.
