One of the major concerns in terms of Structural Integrity for Steel Catenary Risers (SCR) or Fatigue Sensitive Flowlines (FSFL) consists on their strength to withstand dynamic loading along their service life. SCR and FSFL systems always experience

In recent years, the importance of knowing the materials behavior under very-high-cycle fatigue has been pointed out by many research laboratories around the world. An important failure phenomenon has been seen between 10 6 and 10 8 cycles, where the

Offshore petroleum fields frequently pass over areas with uneven seafloor. In such cases the pipeline may have free spans due to depressions crossing and are subjected to complex loading spectra. A major source for dynamic stresses in free span pipel
