Currently, traditional finite-volume Computational Fluid Dynamics (CFD) methods offer a well-proven simulation platform to realize such predictions with a high degree of accuracy. In this work, a novel transient CFD method based on an unsteady linearized free-surface RANS solver is presented for the objective of simulating ship maneuvering. The specific results presented in the paper are for the self-propulsion and turning circle of the Korean Containership KCS. The results achieved, show that the new linearized free-surface RANS solver provides a viable and more cost-effective alternative than traditional Volume-of-Fluid (VOF) methods when applied to streamlined bodies, such as displacement hulls. The key new developments highlighted in this paper are in the way that self-propulsion is included and a new robust mesh motion method to handle the relative motion of the rudder.enhttp://rightsstatements.org/vocab/InC/1.0/ManeuveringPMMPropellerRANSResistanceRudderTechnikIngenieurwissenschaftenConference Paper10.15480/882.336910.15480/882.3369Fluiddynamik und Schiffstheorie M-8Other
