Virtual captive tests as a new tool for early maneuvering performance assessment

Maneuverability is an important aspect of ship performance, and often evaluated in late stages of ship design process. In order to include maneuvering assessment in the early design stage, virtual captive test (VCT) method have been developed as a new tool for early maneuvering performance assessment. In this study, a destroyer hull form with complex appendages and a MR tanker have been analyzed with VCT. Hydrodynamic coefficients were compared to the captive model tests for both hulls and maneuvering simulations of the destroyer hull form is presented in comparison to model tests
