Abstract The arrangement design of the ship mainly depends on the previous mothership data or the experience of experts because there are various restrictions of the owner and the classification regulations. Therefore, it is difficult to select the optimal design by examining various alternatives. Accordingly, a method that can review and optimize various arrangement designs before construction is required. Digital twin technology is one of the methods by which alternatives can be considered before production by creating digital replicas of real physical entities. This study propose a method for designing an optimal arrangement that satisfies the requirements of the ship-owner and several design rules and implements the result as a virtual twin. In the arrangement design process, locations of partitions dividing compartments and locations of each equipment are set as design variables. Furthermore, as objective functions, building cost, stability, and the feasibility for expert knowledge are considered. Also, the arrangement designed during the optimization process can be reviewed by the designer in advance as if the arrangement is actually manufactured through virtual twin. The effectiveness of the method proposed in this study is verified by applying it to selecting the optimal arrangement design for an actual ship. In particular, it has a differentiated advantage from the existing arrangement design optimization method in that the designer can visually review the design first.
