It is expected that the automatic control mode will become the main mode in the future. During the process of ship underway replenishment, interaction disturbances between two ships exist, which should be accounted for controller design. In this paper, the ship-to-ship hydrodynamic interactions are analyzed by using Computational Fluid Dynamics (CFD) method. The influences of transversal and longitudinal distance between two ships on the hydrodynamic interactions are illustrated. The details of the flow filed, such as pressure distributions on the two ship hulls and wave patterns are discussed to get a deeper insight into the physical flow mechanism during the underway replenishment. Then the ship motion model in consideration of the hydrodynamic interactions between two ships of underway replenishment is presented. The model predictive control (MPC) technology is adopted to control the yaw motion. To minimize the cross-track error and compensate for the drift effect caused by the hydrodynamic interactions between two ships, the integral line of sight (ILOS) guidance law is used for generating the desired heading angle. Finally, the computer simulations are conducted to evaluate the efficiency of the controller.enhttp://rightsstatements.org/vocab/InC/1.0/Adaptive target trackingComputational Fluid Dynamics (CFD)Ship to ship interactionUnderway replenishmentTechnikIngenieurwissenschaftenConference Paper10.15480/882.335210.15480/882.3352Fluiddynamik und Schiffstheorie M-8Other
