In recent years significant advances have been made in the development of methods and modeling procedures for structural assessment of marine structures. Various assessment methods are incorporated in the methods used to analyze and design efficient ship structures, as well as in the methods of structural reliability to be used to ensure the safety and environmental behaviour of the ships. Advances in Marine Structures deals also with the fabrication of ship structures, and collects the papers presented at the 3rd International Conference on Marine Structures (MARSTRUCT 2011, Hamburg, Germany,
