Umbilical modeling aids fatigue prediction

摘要

As water depths increase, modeling techniques must keep pace. Until recently, interactions between internal components of an umbilical have been more or less neglected in modeling for fatigue prediction. However, in deeper waters and larger umbilicals, such interactions can contribute significantly to creating the conditions for umbilical failure. DeepSea has independently developed a suite of tools and processes for evaluating the internal performance of large umbilicals in deep water. These tools and processes allow the quantification of inter-component friction stresses as an integrated part of current project execution processes. They enable users to make informed adjustments to designs before building and testing them, thus enhancing the design process, reducing installation risk and helping to contain costs through the entire lifecycle of the dynamic umbilical.
