Abstract

As part of the continuum growth of the shipping industry, new challenges arise for the engineers. The development of floating structures capable of withstanding accidental loads, such as grounding and ship collisions, become nowadays an integral part of the design process. The current paper presents a methodology for impact analysis using FEMAP software capabilities in two distinct stages. The first stage consists of the impact analysis using a rigid indenter displaced at different speeds. The second stage of the study evaluates the impact analysis considering both the indenter and the structure deformable. Mesh influence tests, as well as the influence of the type of elements used in the analysis, have been taken into consideration in the present study.
