In 1995, a joint effort was begun, under the auspices of the NIST ATP, to design, develop and test a composite production riser (CPR) suitable for deep water (3000 to 5000 feet) applications. The objective of the effort is to arrive at a cost-effective design for a composite production riser that meets reliability performance of current metal systems. An integrated CPR design meeting the project cost, weight and performance goals was developed. A test program was defined to derive statistically sufficient data on mechanical properties and to identify failure modes and locations to achieve the required confidence in design, fabrication, and short and long term performance of the CPR. A total of 80 prototypes were fabricated and tested for ultimate strength determination, static and cyclic fatigue performance, and characterization of damage tolerance. A primary purpose of this testing was to correlate and analyze riser joint actual performance with predicted values, in the interest of verifying static and cyclic performance and manufacture variability. The final results of this testing and analysis are presented in this paper.
