Numerical and experimental study on the wave-body interaction problem with the effects of forward speed and finite water depth in regular waves

In this study, a time domain higher-order Rankine panel method is developed and applied to evaluate the wave-body interaction problem in shallow water and regular waves. The hydrodynamic effects of forward speed and finite water depth are accounted for. In order to verify the proposed numerical method, the Duisburg Test Case (DTC) container ship is chosen as a study object. The numerical results of the wave-induced ship motions and the added resistance are validated against the data of model tests, which were carried out in the Towing Tank for Manoeuvres in Confined Water at Flanders Hydraulics Research (FHR) in cooperation with Ghent University (UGent) as part of the SHOPERA project. •A time domain higher-order Rankine panel method is developed for seakeeping analysis.•The DTC model advancing in shallow water waves is taken as the study object.•Model tests are carried out in the Towing Tank for Manoeuvres in Confined Water.•Numerical and experimental results of ship motions and added resistance are compared.
