This work deals with the fatigue assessment of a FPSO converted from a tanker based on a finite element analysis. The finite element calculations are performed on two levels including global and local detailed analysis. Due to the difference of sea state conditions and wide of operations of the initial and converted vessels two different models are used for modelling entire operational life of the ship initially built as a tanker and 20 years later converted to a FPSO. The models cover all particularities of the vessels including environment, sea state conditions and structural differences achieved after the conversion and it is used to conduct a complete stochastic spectral fatigue analysis for entire service life of an already converted 25 year FPSO. Two hot spots are analyzed accounting for the combination of all loading conditions and fatigue damage of entire operational life is assessed.
