Viking Systems has designed and analyzed riser support structures on several FPSO vessels. These structures are added to the side of the FPSO and receive loading from both static and wave hull girder loading as well as static and dynamic loading from the risers themselves.

Viking Systems has developed technology within the SAGA program to manage:

  • Hundreds of combinations of hull induced and riser induced stress combinations to be able to ensure that all strength design conditions are met
  • Thousands of sea state induced fatigue stress ranges using Weibull and Rayleigh distributions
