Design concepts of propulsion and steering system for hotel unit of two-segment inland waterways ship

This paper presents design assumptions and two conceptual design solutions of the propulsion and steering system for the hotel barge constituting a part of two-segment inland and coastal navigation ship. Both presented solutions are based on application of a small-power bow thruster with fixed propeller placed in a rotatable nozzle. In one of the solutions the propeller is driven by a hydraulic motor and in the other – by an electric motor. In both solutions the thruster’s column rotating is driven by a hydraulic cylinder.
