Rigid jumpers

Subsea Jumper Spools

2H Offshore is the industry’s leading expert in dynamic jumper design and analysis. Our highly experienced team has a detailed understanding of jumper response making it easy for us to help you determine a jumper configuration that will accommodate the loading and installation tolerances of your system.

We have expertise in all aspects of rigid jumper design, including extreme loading, first order fatigue, VIV fatigue, thermal expansion and slugging fatigue, and have conducted the detailed design of rigid jumper spool systems for free-standing risers, flowline-manifold and flowline-well applications around the world. Our expertise also covers installation aids design, material selection and procurement support.

Rigid jumper systems have the contradictory design requirements of needing flexibility to accommodate extreme loading and installation tolerances, whilst avoiding excessive fatigue loading that may be generated from fluid flow, direct hydrodynamic loading or excitation from attached riser systems. Determining a design for a system that is typically subjected to numerous design changes requires a highly experienced team with a detailed understanding of jumper response to help design a suitable configuration.

Did you know?

Rigid jumpers are often used for base connection of a freestanding hybrid riser with the subsea pipeline system. However, when large installation tolerances and pipeline movements must be accommodated, the rigid jumper design may need to be changed from a straight forward quasi-static to an extremely dynamically driven design .
