The upper ball joint in a marine riser, in deep drilling, can cause fatigue damage in the drill pipe passing through it. A study of fracture mechanics and S-N curve approaches has been performed to determine the dynamic fatigue damage in the drill pipe. Miner's Rule is utilized in both methods to determine the total damage. The results of both methods are compared.
