Characterization of fluid-structure interaction on the hydrodynamic performance of different ship hulls is presented in this paper. This research aims to investigate the influence of fluid-structure interactions on hydrodynamic performance of ship hull. A ten-step research methodology was applied, in which two different hull forms were considered and modelled using ANSYS. The hull forms having different configurations were set at the same operating conditions to determine their hydrodynamic performance. The result obtained showed that hull type-A, with a flat surface and square edges, had a wetted surface area of 1.93m2 and coefficient of total resistance of 0.26, while type-B hull which is streamlined had a wetted surface area of 1.84m2 and coefficient of total resistance of 0.23. It was confirmed that ships’ hull configuration affects ships’ fuel economy, safety, operational cost, general performance and minimize resistance. The findings will contribute to the optimization of hull designs, enhancing the efficiency, stability, and overall performance of ships in diverse operational environments. By understanding the complex interplay between the fluid flow and the ship hull structure, engineers can optimize ship designs to minimize resistance, enhance fuel efficiency, and ensure safe operation in challenging maritime environments. This research holds significance for the maritime industry, offering valuable knowledge for the design and engineering of ships to address challenges related to hydrodynamic resistance. It will also be of interest to policymakers and environmental groups who are interested in reducing the environmental impact of shipping.
