This work reports on the methodology, validation and application of a computational three-phase flow model for offshore grounding and jacking operations. Such applications feature fluid-soil-body-interaction, topological changes and large relative motions between different parts of the structure, which requires a well-working mesh update strategy and a soil model. Therefore, an additional granular soil phase is embedded into an efficent, parallel finite-volume Navier-Stokes procedure based on an overset grid approach. The overset grid approach is evaluated with regard to the influence of different interpolation and flux-correction practices. The granular soil model is validated by the simulation of dam break experiments and successfully applied to challenging large-scale offshore simulations.
