Abstract

The paper concerns the use of numerical structural analysis in shipbuilding technology as a tool for easier decision-making in the early production stage. Relevant state-of-the-art software packages are user-friendly so the users may focus on model generation, setting up the loads and other calculation parameters and, fi nally, on the analysis of the results. Once the model of the structure is generated it could be used for different cases studies. The necessary changes in the
structure are easily modelled and analyzed again.
The problems related to early outfi tting are explored using the fi nite element method. Structural analysis is performed, fi rst, to determine behaviour of the structure during outfi tting at the ground level. Then, it is applied to analyze the lifting of the outfi tted block for the assembly into a ship superstructure. Deformations and stresses will be evaluated and critical issues detected. As a result, feasibility of the early outfi tting will be evaluated and commented.
