Studies on Three-Dimensional Slamming on Slender Ships

Abstract : The focus is on the understanding of the impact phenomenon at relatively low Froude number (Fr = O(1)). In particular, our objectives are to quantify the range of validity of existing asymptotic theories (using the high Froude number assumption, Fr >> 1), and to understand the gravity effect upon the impact process. This study is of direct relevance to accurate prediction of hydrodynamic loads associated with ship slamming and breaking surface wave impact on offshore structures.
