Shenzi 16-Inch Oil Export SCR CVA Verification

摘要

In 2006 Enterprise developed a 16-inch oil export system from Shenzi field located in Green Canyon Block 653 in the Gulf of Mexico, approximately 120 nautical miles offshore in approximately 4,375 ft of water depth. The oil export system is attached to the Shenzi TLP host facility. The 16-inch oil export SCR system is subject to the CVA (Certified Verification Agent) verification required by MMS (Minerals Management Service) 30 CFR Part 250 [Ref. 1]. NTL No. 2007-G14 [Ref. 2] was issued pursuant to 30 CFR 250.103 to provide clarification and guidance for pipeline riser design, fabrication, and installation under the platform verification program specified in 30 CFR 250.909 through 918. This paper summarizes the 16-inch oil export SCR CVA verification procedure. This paper presents a systematic SCR CVA verification procedure. The CVA verification procedure includes SCR CVA verification preparation, and verification of SCR design, fabrication, and installation. The verification procedure and table formats developed are unique and applicable to other types of pipeline risers in the Gulf of Mexico.
