To design eco-friendly ships, the hydrodynamic behaviour of the hull has to be estimated precisely. The first and
foremost one is the ship resistance, which is closely related to the energy efficiency of the ship. Different
extrapolation methods, based on different assumptions, have been used to predict the full-scale ship resistance
from model-scale experiments. In this manner, it is important to understand the scale effect on the individual
ship resistance components. In this study, URANS CFD simulations of KCS and KVLCC2 were conducted at
different scales. The total resistance components were decomposed into the individual resistance components to
investigate the scale effects. The simulation results were compared with full-scale resistance predictions using
different extrapolation methods and the rationale of the different compliances between them was investigated.
Finally, the hydrodynamic characteristics in different scales were examined.
