摘要
The accurate assessment of fatigue damage is a crucial issue for the design of marine pipelines. In this study, we modified the approach of Zheng et al. (2007) to simulate the random wave elevations for the fatigue assessment of marine pipelines applied to intermediate seas, e.g., the Persian Gulf. The cumulative fatigue damage due to the bending stresses and the linear and nonlinear acting wave forces was estimated on the basis of the finite element program for free-spanning sections. The results showed that the fatigue damage is highly dependent on both the wave characteristics and the modeling approach for the irregular wave.
