Abstract
This paper presents a simulation of ship speed for an existing containership at EEXI draft using Computational Fluid Dynamics (CFD). The simulation is divided into two steps namely (a) the numerical prediction of ship performance at model scale, and (b) the extrapolation of results to full scale. Model scale numerical simulations of ship resistance, open-water propeller and ship-propeller-rudder interactions at demonstrated. The method is at first validated by comparing against available experiments and at second stage full-scale ship performance is assessed by an extrapolation method. Comparison of the ship speed predicted by CFD against experiments demonstrates a difference of 0.05 knots when the same extrapolation coefficients are applied.
