VAM® TTRTM is a threaded and coupled riser connector featuring a very high fatigue resistance (SAF ≤ 1.5 vs. DNV B1 curve). It was specifically designed as an outer production riser for years of reliable use in high fatigue environments.
VAM® TTRTM features am external metal to metal seal to prevent seawater ingress and buildup of corrosion over design life. It also includes a fatigue compliant gas tight internal metal to metal seal derived from our premium casing and tubing connections. Additional Fatigue enhancements include stress reducing bending swoosh and special designed fatigue reducing threads
VAM® TTRTM has been successfully run in multiple projects over the last ten years. It is the industry standard for high fatigue applications.
