Integrating potential flow code for ship bank interaction at real time simulations

The MARIN simulator utilizes an advanced method that runs on graphics processing units (GPUs) to estimate the hydrodynamic loads that occur when a ship navigates near a bank. This method is based on potential flow theory, which is particularly useful for modeling fluid flow around ships in various maritime conditions. Series of model tests, Computational Fluid Dynamics simulations, RAPID calculations and Extensible Modelling Framework (XMF) simulations using the Flow Interaction node were conducted using a 135-meter inland ship, which was equipped with two ducted propellers and four Schilling-type rudders. This study investigated the impact of key parameters—such as sailing speed, water depth, and proximity to the bank—on suction/repulsion forces. The results were analyzed with the initial aim of assessing the feasibility of the Flow Interaction code for practical applications at real time simulator. At this stage, the research focuses on understanding and refining the code’s behavior in shallow water.
