RISER ANALYSIS

Entagral offers analysis support for a host of different riser types and applications including flexibles, steel catenary risers (SCRs), top tension risers (TTRs), hybrids and umbilicals.  Analysis can be performed as part of new riser design applications or as a verification of existing riser designs.

Riser design and analysis applications include:

  • Riser configuration design to API 2RD and other relevant industry codes
  • Riser configuration selection including buoyancy size and location as well as top tension specification
  • Flex-joint specification and stress joint design
  • Riser touchdown response analysis including riser-soil interaction modeling and fatigue response calculations
  • Structural design of flexible riser accessories such as riser bases, bend stiffeners, subsea arches, clamps, etc.
  • Vortex Induced Vibration (VIV) response analysis and VIV suppression design including strake configurations
  • Jumper configuration design at riser base on seabed
  • Consideration of riser interference for crowded turrets
  • Tow-out & installation analysis and development of installation procedures
