Maneuvering analysis of a vessel equipped with two azipods using its mathematical model
Azimuth propulsion systems (azipods, screw-steering columns, SSC) are widely used on new types of vessels intended for the implementation of large-scale projects for the integrated development of the Northern Sea Route. The main way to study the operation of such vessels is their mathematical modeli...

Azimuth propulsion systems (azipods, screw-steering columns, SSC) are widely used on new types of vessels intended for the implementation of large-scale projects for the integrated development of the Northern Sea Route. The main way to study the operation of such vessels is their mathematical modeling with the inclusion in the model of both the hull of the vessel and the azimuth propulsion that it is equipped with. The model is complicated when the ship is equipped with not one but two azipods, which in the process of work affect each other in a certain way. During the study, a complicated model of a ship with the displacement of about 36 thousand tons, equipped with two azipods, has been considered. The hull is described using the model in displacements, the operation of each azipod is described using the algorithm of A. D. Gofman. When determining the base value of the stop of each azipod screw (before it is turned), the action curve of the Lammeren screw has been used.
