Control of thrust vector of wheel propulsion system of the vessel

A distinctive feature of a new passenger ship "Sura" is its propulsion system – two paddle wheels located at the stern of the ship, and the absence of a traditional steering wheel. Shiphandling is realized by means of independent electric drivers of paddle wheels. The navigator may implement a variety of maneuvers, changing the ratio of the rotating speed of paddle wheels. The navigator needs a device, showing the direction and value of the sum thrust vector, in order to effectively control the vessel. Expressions for the value of the thrust vector and its direction were obtained, and it allowed designing such a device. A structure of the control system and display of the propulsion system parameters and its implementation, mounted on the ship "Sura", and put into trial operation in navigation in 2011 are given in the paper.
