Based on the ABS rule's requirements, this paper introduces a fatigue strength calculation method for the integration of the FPSO hose reel support structure. By the hot spot stress analysis means a FPSO is evaluated taking into account its inertia acceleration. Firstly, very fine mesh is modeled to calculate the hot spot stress, then different S-N curves are selected to evaluate the fatigue life of each hot spot. Finally, some suggestions are put forward for structure design near stress concentration area according to the fatigue calculation results.
