Abstract

The added resistance experienced by a ship due to “wind” and “wave” significantly influences its speed, fuel consumption, and overall performance. These forces result from the interaction between the ship's hull and the surrounding wind and waves. Various factors, including ship speed, wind speed, wave height, wavelength, and hull shape, collectively determine the magnitude of the total resistance. The computation of added resistance assumes a critical role in optimizing ship design and operation. By accurately predicting drag components, ship designers strive to formulate hull configurations that minimize drag, thereby enhancing fuel efficiency and reducing emissions. Ship operators can leverage added resistance calculations to make informed decisions regarding speed optimization and routing in various sea states, consequently enhancing the overall performance of the ship. In this study, added resistance calculations for wind and wave resistance on the KCS (KRISO Container Ship) model, extensively utilized in theoretical computations, are carried out, taking into consideration the environmental conditions of the North Pacific Ocean. The analysis commences by comparing results from calm water resistance calculations based on towing tank tests and CFD (Computational Fluid Dynamics) analysis. The investigation then extends to include added resistance induced by varying wind and sea state conditions affecting the ship superstructure when transporting 3600 fully loaded containers at the model scale. Consequently, the impact of added wave and wind resistance is juxtaposed with calm water resistance, offering insights for those seeking information on this subject.
