Abstract: For comparing the two fatigue assessment system of oil tanks given by HCSR and CSR-OT,two oil tanks with horizontal stringer and corrugated bulkhead were selected as research objects. The hot spot stress FEA was carried out with two kind of different applied loads according to HCSR and CSR-OT respectively so as to calculate the fatigue life. The results of fatigue life of the hopper knuckle were compared,showing that HCSR has more reasonable loads and more strict assessment system.
