Abstract: The defect caused by the transportation and fabrication during oil tanker construction become major concern. Especially, on mid-ship section for the largest cyclic bending moment during the operation. The present research elaborates the fatigue life estimation on stiffened panel with T and Y stiffener profile using the IACS CSR. The stress distribution on cross sectional area of stiffened panels with and without defect considered as the preliminary condition for development of fatigue life estimation. The result shows that, the fatigue life estimation of stiffened panel with profile T and Y is 34.95 and 35.46 years. The similar the equivalent stress on stiffened panel with profile T has lower value compared to Y stiffener profile. The defect positions affect the contour stress distribution of stiffened panels with lower value of equivalent stress compared to the stiffened panel without defect.
