Mapping Hull Condition and Finite Element Models for Hull Structure Assessment of Ships in Operation

摘要

This paper describes an approach for hull strength assessment during ship life cycle using 3D models to describe hull condition (HC model) and strength (FE model). In addition to appropriate assessment methodologies of aging structures, an effective data exchange between the HC and FE models is required. The difficulty lies in the different abstraction levels of the 3D models. The first steps for transferring actual inspection results stored in the HC model to the FE model as well as elements of structural assessment such as buckling fields are presented.
