DESIGN ANALYSIS AND FULL SCALE PROTOTYPE TESTING OF AUGER TLP'S 9-5/8" TLP PRODUCTION RISER WELD-ON CONNECTOR

The design, analysis, and full-scale prototype testing of a special threaded connector for use on the Auger Tension Leg Platform (TLP) 9-5/8" x 0.435" wall production risers is summarized in this paper. A flush-bore production riser connector with internal and external metal-to-metal seals, a resilient seal between the external metal-to-metal seal and the external torque shoulder, radial thread interference, and high resistance to fatigue was developed. Finite element analyses and full-scale static, sealability, and fatigue tests verified that the connector satisfied all design requirements. The full-scale fatigue tests verified that the design fatigue curve and fatigue life prediction procedure used yield conservative results and that the fatigue life of the connector greatly exceeds the girth-weld. Consideration of manufacturing methods and tolerances along with gauging, in the early states of the design, resulted in a cost effective connector.
