Sažetak
The spectral fatigue analysis of a structural detail of Liquefied Natural Gas (LNG) carrier is presented. The analysis was performed by means of general hydro-structure tool HOMER (BV), where 3D FEM model for the structure and 3D potential flow code for fluid modelling, respectively, is applied. Mode superposition method is used to calculate ship hydroelastic response in waves. Numerical procedure for the fatigue assessment based on the so called top-down procedure is described in details and applied to determine stress concentrations in fine mesh FE model of a selected structural detail. Based on the calculated stress RAOs and taking into account proper S/N curve, the fatigue life of certain structural detail is obtained for a selected operational profile.
