Improved Collision Safety of Ships by an Intrusion-Tolerant Inner Side Shell
Artikel i vetenskaplig tidskrift, 2009

This paper presents a conceptual deformable inner barrier design with the aim of improving the collision safety during a collision into the side of a ship by facilitation of a deep intrusion before penetration. Validation of the conceptual design was made using finite element simulations in a comparative study of the original "reference" structure. The analysis shows that the amount of absorbed energy can be increased by up to several 100% at the same time as the stakeholders' interests are fulfilled.
