Steel Catenary Riser


ARTICU-JOINT

ARTICU-JOINT™ is a steel catenary riser hang-off component which trades rotational movement of pipe above the hang-off point for a simplified and robust SCR weight bearing articulation.

WEIGHT-JOINT

WEIGHT-JOINT uses proprietary technology to apply a significant amount of weight on a riser (per unit length of pipe) whilst maintaining the project flexibility to either reel or j-lay.

TDZ-JOINT

Highly optimized steel catenary risers involving the use of special joints in their touch down zone are a feature of modern deep-water systems. Research has shown that including joints of SCR pipe made from titanium is an effective method of improving SCR fatigue and stress response at the touch down zone. Although titanium costs are significant its use in such joints is cost effective by comparison with in-service operational techniques to manage riser fatigue or riser replacement. The couplings between these joints have thus far been flanged. Technology now exists to make the titanium pipe sections weldable.

STRESS-JOINT

STRESS-JOINTs are routinely used as a curvature control component at the fixed end of a riser. The upper S-J (by contrast with a lower stress joint) has to manage both curvature and tension loads. Although mission-critical components both the upper and lower S-J experience fatigue service and therefore their manufacture is crucial for long term integrity. SRP is the supplier of choice for STRESS-JOINTs.
