... VIV fatigue damage of the subsea umbilicals is impacted by both the umbilical cross-sectional design (geometry, mass, materials) and the global configuration. Subsea umbilicals are subjected to complex interactions due to the friction and sliding between the internal layers and components. When...

Development of Load Optimizer Besides the reassessment of the Hull fatigue damage considering the actual past service life, the obtained results and practical correlations provide the necessary information for developing a computational tool to optimize the loading conditions...

.... A computational model of pipeline fatigue damage, which is affected by temperature and pressure mainly, in the pipelines is developed to predict the fatigue damage under specific circumstances. Integration of multiple sensors in the pipeline can avoid early failure and maintain it proactively. CO 2 could...

.... The digital twin system comprises three main components. A computational finite element-based model of the crack defect in the pipe is developed to calculate the stress intensity factor (SIF) for different crack lengths and depths. The computation model is used to estimate the fatigue damage. The input...
