MOORING SHIP WITH PROPELLER STEERING COMPLEX

In Russia, a passenger ship is being built that has a unique set of propulsion units - two propellers and an azimuth thruster. The traditional rudder is missing. The vessel is controlled by changing the ratio of twin-propeller rotational speeds, which imposes increased requirements on the navigator's qualifications, especially when performing mooring operations. The specified set of propulsion units gives the ship unique properties - it allows the vessel to move broadside in any direction. This allows significantly simplifying the process of mooring a vessel. In this paper, a possibility of automating the process of mooring of a propelled vessel is reviewed. A control algorithm that provides an automatic mode of approaching vessel the mooring berth is proposed, the dynamic characteristics of the vessel during the implementation of this algorithm are investigated. The area of the proposed algorithm efficiency is determined when changing the strength and direction of the wind. The results will be used in the design of the control system of the "Golden Ring" propeller vessel under construction.
