This research paper investigates the slamming wave impact on a ship hull in the Northern Straits of Malacca where actual motion data were collected. Slamming is a phenomenon which occurs when a ship or a part of it hits the water surface with high velocity, causing high pressures and vibrations, which affect the safety and performance of a ship. Slamming is a type of fluid–structure interaction (FSI) issue which occurs when a structure interacts with fluid on a surface. In this research, a two-way FSI model was developed using the ANSYS Workbench software, in the fusion of hydrodynamic diffraction and finite element analysis (FEA). ANSYS is a FEA software which has been employed to perform structural analysis using advanced solver options, including linear dynamics, nonlinearities, thermal analysis, materials, composites and hydrodynamics. The results showed that the maximum hydrostatic and hydrodynamic pressures due to slamming were over 1700 MPa. This research highlights the significance of predicting slamming in the context of ship design and safety assessments. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
