Ren, H.L., Xu, C., Zhou, XQ., Sutulo, S. e Guedes Soares, C. (2019), “A numerical method for calculation of ship-ship hydrodynamics interaction in shallow water accounging for sinkage and trim”, Proceedings of the ASME 2019 38th International Conference on Ocean, Offshore and Arctic Engineering (OMAE 2019), 9-14 Junho, Glasgow, Escócia, UK
Sinkage and trim, which often occur to ships moving shallow water, do not only have an effect on the ship-ship hydrodynamic interaction forces, but also increase the risk of grounding. An algorithm based on the potential theory has been devised for real-time simulation of the hydrodynamic interaction between two ships in shallow water accounting for sinkage and trim. The shallow water condition is modeled using the mirror image method; while the sinkage and trim are solved iteratively based on the principle of hydrostatic balance, where a mesh trimming procedure of the mesh is performed when the waterline is changed. Simulations are performed with and without accounting for the sinkage and trim, and comparison with experimental results shows a fair agreement.
