• Full-scale CFD simulations of a post-Panamax 6750 TEU containership • Virtual disk method employed to model the effects of the rotating propeller • Trim effects on resistance and propulsion characteristics are quantified • Numerical results validated against extrapolated towing tank measurements • Detailed insights into the flow field around the containership are provided This study presents a comprehensive full-scale numerical investigation of the resistance and propulsion characteristics of a post-Panamax 6750 TEU containership at various trim angles. The numerical simulations are conducted using Reynolds averaged Navier-Stokes equations coupled with the shear stress transport k − ω turbulence model. The dynamic fluid body interaction method is employed to allow the ship to freely heave and pitch, while the effects of the rotating propeller in the numerical simulations of the self-propulsion test are modelled using the virtual disk method. A thorough verification study is performed to ensure the accuracy and reliability of the numerical results. A validation study was also conducted through comparison with the available experimental data, showing good agreement. The findings demonstrate that the adopted numerical approach accurately predicts the ship resistance and propulsion characteristics across different trim angles. The results highlight the significant influence of trim on ship performance, providing valuable insights for optimizing trim angle during its operation.
