To obtain the hydrodynamic derivatives of the KVLCC2 model ship with different water depths and ship-bank distances, the simulation of PMM tests are carried out using an unsteady Reynolds-Averaged Navier–Stokes (RANS) based solver. Hybrid dynamic mesh technique is proposed to realize the simulation of pure yaw tests in confined water. Studies on the grid convergence and time-step-size convergence are firstly performed. Hydrodynamic derivatives for the ship in different water depths and ship-bank distances are compared. The course stability is investigated based on time-domain simulations and eigenvalue analysis, and the results show that the ship-bank interaction and shallow water effect have a remarkable influence on the course stability.}, doi = {10.12716/1001.12.04.14}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Safety at Sea, Hydrodynamics, Ship-Bank Interaction, Hydrodynamic Derivatives, Circulating Water Channel (CWC), User Defined Functions (UDF), Planar Motion Mechanism (PMM), Reynolds Averaged Navier Stokes (RANS)} }
