API TR PER15K Protocol for Verification and Validation of HPHT Equipment Addresses MMS 30 CFR 250.807 (NTL 2007-G07) for HPHT Equipment HPHT Equipment: Completion and Well Control Equipment Pressure rating > 15,000 psi or temperature rating > 350°F Pressures and temperatures at seafloor Includes: Functional Design Specification (User requirements) Technical Design Specification (Mfg requirements) Best Practices and Guidance (heart of document) 11/9/2018 PER15K Status - 2/9/2010

Functional Design Specification User should provide a Functional Design Specification Environmental conditions All loads throughout life cycle Internal pressure External pressure and loads Thermal requirements Any other loads Life cycle requirements Applicable industry standards 11/9/2018 PER15K Status - 2/9/2010

Technical Design Specification Manufacturer document Technical Design Specification Confirms design meets the Function Design Specification Should address: Environmental conditions Loads and characteristics Life cycle requirements System analysis loads Industry standards Design verification analysis Design validation testing Manufacturing process specification Fit-for-service basis After market activities 11/9/2018 PER15K Status - 2/9/2010

Fit-for-Service Basis The foregoing functional and technical design specifications define fit-for-service requirements. The User and Manufacturer should agree upon and document the basis for acceptance of the equipment. Acceptance may be based upon: Proven E&P experience or technology, Proven alternate industry experience or technology, Advanced design development, verification, and validation requirements, or A combination of the previous elements. 11/9/2018 PER15K Status - 2/9/2010

Best Practices and Guidance Material selection (still being developed) Design verification analysis Analysis demonstrates fit-for-service design Analysis method applicable to failure mode for component Elastic-plastic analysis recommended for heavy-wall vessels Fatigue analysis for components exposed to fatigue loading Design validation testing Validates fit-for-service design Tests requirements can be based upon output from FMEA process Considers affects of combined loads from system analysis Internal and external pressure External applied loads Thermal loads 11/9/2018 PER15K Status - 2/9/2010
