Abstract: To calculate the steel catenary riser's(SCR) fatigue damage induced by wave, motion response of Spar platform was proposed by using professional software Hydrostar, and motion-frequency functions of Spar were calculated. Harmonic analysis of steel catenary riser was provided by using finite element software A NSYS, and stress-frequency functions of SCR were computed. The fatigue damage of riser is analyzed by using Miner's linear cumulative damage theory, S-N curve and internal damage procedures. Test was done on a typical deep-water riser, and calculation results show that wave-induced fatigue damage on riser top location is stress concentrated.
