Within this work a simulation-based approach using fluid-structure interaction (FSI) for the assessment of sideways launching of ships based on an Arbitrary-Lagrangian-Eulerian (ALE) approach is proposed. The results of the ALE approach are compared to common approaches (use of rules / regulations, analytical formulations, model tests and simulations without FSI). Based on the ALE approach two different load mechanism acting upon a ship can be observed: the impact with the water surface and the deceleration of the hull structure. The second load mechanism could only be observed based on the proposed ALE approach. In addition, the influence of different parameters of a sideways launching process is investigated.
