Abstract:Combining with 300 thousand DWT crude oil terminal project in Dalian new port, fatigue damage of jacket platform in a harbor subject to ship's impact was researched. The structure's internal force under ship's impact was calculated using the finite element software ANSYS. The hot stress in the joint was gained by multiplying the corresponding stress concentration factors to nominal stress of the structural components. The S-N curve in the code of DNV was used to calculate fatigue damage of the joint under ship's impact. It concludes that using grouting joints can effectively reduce the stress concentration factors of the tubular joints, then improve the fatigue life of the structure.
