Abstract
Free-running model tests for the KRISO Container Ship (KCS) maneuvering in calm water and waves at Froude numbers 0.157 and 0.260 are assessed for facility biases and scale effects via comparisons of the results from multiple facilities. CFDShip-Iowa results are compared with experiments to assess CFD accuracy. Key variables from propulsive performance, self-propulsion, turning circles, and zigzag maneuvers are analyzed for variability and accuracy, highlighting those with the greatest influence on overall performance. Correlation curves show good agreement in self-propulsion performance. Turning circles in calm water at both Froude numbers show greater variability in the primary variables on the starboard side compared to the port side, while the secondary variables exhibit less variability overall. In waves, the primary variable variability increases, and the secondary variable variability decreases compared to the calm water case. CFD-EFD comparisons in calm water show larger differences in primary variables during port side turns, and smaller differences during starboard turns. In waves, both turning directions show larger errors in primary variables. Roll-related variables contribute most to variability and differences. For zigzag maneuvering, increased variability is observed under port side heading conditions, partly due to the small rudder angle.
