ABSTRACT
This chapter aims to compare and validate the results of SHARP with Non-linear Finite Element Explicit Code, Level Set-DYNA within the scope of A.D.N. Regulations. ICAM and Bureau Veritas have been involved in the development of an intermediate damage assessment tool called SHARP based on the super-element method. Some validation tests have already been performed on ocean-going tanker and Floating Production Storage and Offloading application cases. A. D. N. suggested using Finite Element Analysis to determine the collision energy absorbing capacity. The basic idea of the so-called “super-element method” consists of splitting the vessel into several structural macro-components known as super-elements. During the collision process, the energy absorption capacity, collision forces and the penetration into the struck ship are evaluated along with the activation of the super-elements involved in the process. The rupture strain considered in SHARP needed to be tuned in order to correctly model the loose of stiffness of the super-elements such as side shells and stiffeners.
