The paper reports on the predictive prospects of the Smoothed-Particle-Hydrodynamics (SPH) method for jacket launching and foundation installation simulations. The type of considered applications usually involves the interaction between floating structures (e.g. barges and jackets) as well as structures and seabeds. Such scenarios pose challenges to mesh-based solvers, particle methods like SPH therefore are of advantage. The presented procedure captures floating body motions using a quaternion based 6DOF motion solver. Fluid/Soil interaction is predicted by an adequate suspension model. An efficient parallelization strategy is applied together with a dynamic variable resolution approach to handle large computational domains and structural details requiring a rather fine discretization.
