Optimizing Ship Hull Design: The Impact of Chine Configurations on Resistance and Power in Semi-Planing Hulls at High Speed

Abstrak

In the world of marine engineering, hull design is very influential on the hydrodynamic efficiency of the ship. This study aims to analyse the effect of single chine and double chine hull design modifications on the ship's drag and power requirements. The reference hull model is used as a reference and has been validated using existing hydrodynamic data to ensure accuracy. Furthermore, single chine and double chine design modifications with a width of 15 cm each were applied. Computational simulations were performed at various trim angles (0°, 1°, 2°, and 3°) and Froude numbers to evaluate the drag performance. Results show that the single and double chine configurations result in significant drag reduction compared to the benchmark model, with the double chine design providing the most optimal results. These modifications not only improve the hydrodynamic characteristics, but also reduce the power requirements, thereby improving the overall efficiency of the vessel. This research emphasises the importance of accurate modelling and validation in assessing hull design changes. Overall, the application of chine changes, especially double chine, is a practical and effective approach to improve ship performance through reduced drag and energy consumption.
