Rigid Jumpers

There are no translations available.

Rigid jumpers are typically used as an interface between more substantial subsea structures (risers/flowlines) and are required to accommodate significant static and dynamic loads. The response of the jumper is often complex, involving a variety of loading mechanisms, and can be highly fatigue sensitive.

2H Offshore is the industry’s leading expert in dynamic jumper design and analysis. Our considerable experience responding to rigid jumper problems, conducting jumper inspections and specializing in jumper monitoring and analysis has allowed us to feed this knowledge back into our jumper design methodology. We undertake a coupled riser/jumper analysis approach where both components are designed as a system, taking into account various key design considerations.

Jumper design considerations:

  • Strength analysis
  • Slugging
  • Cross-flow and in-line VIV
  • Riser base excitation
  • Soil damping
  • Flow induced vibration
  • Installation procedures
  • Connector installation, sealing and capacity
  • Erosion and corrosion
  • Manufacturing quality
  • Material choice
  • Insulation and coating
  • Design codes and standards
