Technical follow-up of the Umbilical package.Helica is a vital component in an overall computational consistent and highly efficient fatigue analysis scheme.Integrated within the RIAU team the Project Engineer will be involved in the tender and/or project for either one (or more) of the following subjects: The long-term stress cycle distribution will therefore require global dynamic time domain analysis followed by a detailed cross-section analysis in a large number of irregular sea states. The basis for assessment of fatigue damage of such elements is the long-term stress cycle distribution at critical locations on the helix elements caused by long-term environmental loading on the system. Fatigue of cross-section components such as helix tensile armors and steel tubes is a critical design issue for dynamic umbilicals and flexible pipes. of subsea umbilicals and flexible pipes, subjected to extreme and fatigue loading, is a challenge to the industry.
Stresses in dynamic umbilicals and flexible pipesĪccurate evaluation of local stresses in complex cross-sections, e.g. The main functionalities of the Helica software are: Helica is tailor-made software for cross-section analysis of flexible pipes and umbilicals and is validated against high quality stress measurements in a full-scale subsea umbilical. Cross-section analysis and fatigue analysis of umbilicals Using Helica, subsea engineers can reduce the analysis time to a fraction, as thousands of simulations may be performed in minutes.
The Helica software module in Sesam includes technology that represents industry consensus for cross section analysis of umbilicals and flexible risers, including fatigue analysis of section components such as helix wires and steel tubes.
