The optimization of ship resistance is an important method to reduce the fuel consumption and improve the ship energy efficiency. The wind resistance of container ships accounts for a much larger proportion than that of other ships, which is a nonnegligible important part. The installation of a fairing at the bow has a significant effect on the wind resistance of the container ship. The total resistance and the wind resistance of a fully loaded container ship sailing at the design speed are calculated by using the computational fluid dynamics (CFD) technology. The mechanism of the resistance reduction using the fairing is analyzed by studying the reduction of the wind resistance and the total resistance due to the fairing when facing the wind at different wind speeds. The fairing can guide the flow and delay the flow separation, which effectively reduces the pressure resistance between the front and rear of the ship. The reduction of the wind resistance due to the fairing is stable at about 40%. The reduction of the total resistance due to the fairing gradually increases with the increase of the wind speed, and the resistance reduction can reach 2.91% under the wind speed of scale 8. The results can provide references for the practical design application and resistance evaluation of the fairing of container ships.
