Steel Catenary Risers

We have conducted hundreds of feasibility studies, detailed design and verification projects for a wide range of steel catenary risers of all sizes, functions, vessel types and water depths.

Our extensive understanding and experience of SCRs mean that we can design an optimal and robust configuration while taking into account your technical and commercial considerations.

We are constantly adapting and evolving our approach to steel catenary riser design and integration management as offshore developments move into deeper water and harsher environments. Recently we developed a lazy wave SCR design to accommodate the severe motion and dynamic loading demands of turret connection and relatively shallow water depths.

2H led the STRIDE JIP in the 1990’s and was instrumental in helping the industry address some key areas of SCR design. The JIP was executed over a four-year period, involved more than 20 companies and investigated key design parameters such as touch down point interaction, vortex induced vibration and the effects of pipe reeling on girth weld fatigue.
