The increased offshore construction rate has raised the problem of accuracy and safety of lifting operations carried out by crane ships more acutely. In this regard, researchers turn their attention to the problems of analyzing the hydrodynamic response of crane vessels during the equipment installation and construction of structures. For these studies, multibody dynamics mathematical modeling tools are used, as well as specialized CFD solvers, allowing to determine the impact of the sea environment on the floating bodies. Among a variety of such software, there are both commercial and free programs with their own calculation algorithms and capabilities. In this paper, attention is paid to the approach of modeling a floating crane ship in the time domain using open-source software WEC-Sim and Capytaine, which, in our opinion, have significant advantages over other similar codes. The description of the approach is followed by an example of calculation on an arbitrary configuration of a crane vessel.
