Abstract: With the increasing needs of energy saving and emission reduction, the effects of added resistance on ship navigation performance and the control quality have attracted considerable research interests. The added resistance of ship roll is analyzed based on the potential flow theory, and an added resistance model is presented. The added resistance induced by ship roll is calculated with the hydrodynamic computation software ANSYS-AQWA. The rolling added resistance model is modified with regression analysis, and feasibility of model validated. The relationship between roll attitude and added resistance in the time domain is analyzed based on this model. The results provide a theoretical foundation for controlling ships’ anti-roll capability with minimum speed loss.

Key words: added resistance, potential flow theory, anti-roll
