Riser analysis - Riflex software

Riser analysis

The Riflex software module in Sesam represents state-of-the-art technology for riser analysis suitable for flexible, metallic or steel catenary riser applications. Riflex is an efficient software system for hydrodynamic and structural analysis of slender marine structures. It is also available for coupled analysis of mooring and riser systems connected to floating production unites in deep water.

Key advantage of Riflex

  • Extremely efficient and robust non-linear time domain formulation applicable for irregular wave analysis
  • High flexibility in modelling, enabling analysis for a wide range of structures
  • Continuously verified against model tests and full-scale tests
