Abstract
    Computational fluid dynamics (CFD) has recently undergone remarkable progress in the field of naval architecture. Much research has been devoted to CFD evaluation particularly in the early design stage. This study explored the application of CFD to the estimation of the hydrodynamic forces acting upon a ship hull manoeuvring in shallow water. First, CFD code developed by one of the authors, which has proven effective in flow field analysis, was adapted to the study of manoeuvring hydrodynamic forces in shallow water by introducing requisite improvements in capability and accuracy. Next, this code was applied to a model of a very large crude carrier which has previously been subject to detailed analysis concerning manoeuvring motion. The obtained computational results were found to be in good agreement with experimental data in deepwater, suggesting that this code could also accommodate more complex conditions in the future.
