[en] This paper presents an overview of the state of art of ship impact analysis on lock gates. First, the different kinds of analysis are presented, which are: empirical approach, analytical-rational approach, and finite element methods performed with quasi-static analysis or dynamic analysis. A discussion on the hypothesis and the calculus time required by each method is carried out with a view to clarify the state-of-practice for engineers. Then, a quasi-static analysis by finite elements modeling a ship impact is performed on the specific case of a new lock gate designed in Belgium for the “Seine-Escaut Est” project. The results suggest some design recommendations to provide a ductile behavior and so impact strength for the gate structure.
