Riser analysis software for marine riser systems - Riflex

Riflex software is the market's fastest solver for riser analysis. It is developed with more than 45 years of domain expertise in riser design for flexible, metallic or steel centenary riser systems by DNV.

Riser analysis software

The Riflex riser analysis software module in Sesam represents state-of-the-art technology suitable for flexible, metallic or steel catenary riser applications. Riflex is an efficient riflex analysis 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.

Marine riser software: Key advantage of Riflex

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

Riser design

Riflex is the market's fastest solver for riser analysis. It offers fast and reliable riser design, computing riser motions stresses and fatigue life as well as performing code checks of the risers.

Riflex software for analysis of wide range of marine structures

Our marine riser analysis software can be used for:
  • Flexible risers
  • Top tensioned risers
  • Metallic catenary risers
  • Mooring lines
  • TLP tendons
  • Loading hoses
  • Umbilicals
  • Towing lines
  • Pipe-laying
  • Seismic cables
  • Fish farming systems

Software system for mooring and riser analysis

The capabilities of Sesam software in this area range from riser and mooring riser and moorings design to analysis of marine operation. In addition, the system supports design and fatigue analysis of umbilicals, which sets Sesam apart in the market.

Multi-core computers are supported and the highly efficient, robust solvers (Riflex and another Sesam module Simo) for riser design iterations. The software's graphical modelling saves users significant man-hours during mooring and riser analysis.
