The work of ocean and coastal engineers and naval architects can be supported by computational models for the interaction of water waves and flows interacting with e.g. offshore platforms, coastal-defense works, and ships. One particular boundary-integral equation method based on a potential-flow model is further developed. After a description of the method, it is verified and validated in two dimensions by calculating fluid forces on oscillating surface-piercing bodies, as well as highly nonlinear waves in a tank. The description of the fluid-body interaction is elaborated and extended. The numerical algorithm for this interaction is improved. An alternative body-boundary condition and algorithm are derived and designed. Further improvements to the numerical method are also described. Three-dimensional calculations for forced and freely floating bodies give good results. Conclusions and recommendations for further work are given.
