Dynamics of shaft lines of the landing ships

Abstract

The paper presents an analysis of the dynamics of the shaft line of landing ship manoeuvre during grounding at a landing area. The work characterises the specific features of shallow water interactions on the propeller operation. There is a characteristic structure of the ship's propulsion system. Potential operational hazards arising from the problem of grounding and descent from shore shoals of a landing ship have also been identified. A model of sandy water interaction on propellers' torque was proposed for the dynamic calculations of shafts' loads. The results of the simulation of torsional vibrations on the shoal area are presented as well.
