Functional Design Specification User should provide a Functional Design Specification Environmental conditions Temperature, exposed fluids, corrosion/erosion, operational environment Loads and characteristics Pressures, temperatures, internal loads, external loads, thermal gradients, temporary conditions, cyclic loading, combined loading, and system analysis and integration Life cycle requirements Applicable industry standards 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

Technical Design Specification Manufacturer document Technical Design Specification Confirms design meets the Functional Design Specification Environmental conditions Loads and characteristics Life cycle requirements System analysis Industry standards / regulatory requirements Design verification analysis Design validation testing Manufacturing process specification Fit-for-service basis After market activities 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

PER15K Report - SC6 Meeting 6/30/2010 Gap Analysis API TR PER15K Is a technical report, thus has no requirements 30 CFR 250.807 Must demonstrate equipment is capable of performing in the applicable HPHT environment Include design verification analysis Include design validation testing 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

PER15K Report - SC6 Meeting 6/30/2010 Gap Analysis NTL Draft 3/29/2010 Material mechanical properties per ASME Div 3 KM-2 Increased material toughness Design verification Elastic-plastic analysis per ASME Div 2 Part 5 Fatigue analysis per ASME Div 3 Design Validation Hydro test per ASME Div 2, Part 8 Construction NDE per ASME Div 3, KE-3 Monitoring of Loads 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

Gap Analysis – API Spec 6A No requirement for User’s Function Design Specification Pressure rating [4.2.1] Need higher pressure ratings – 25 ksi and 30 ksi What pressure increments? 5 ksi increments??? External loads are not addressed [4.2.1.3] Need to address system loads Temperature rating [4.2.2] Need higher temperature ratings – currently 250°F max What temperature increments? 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

Gap Analysis – API Spec 6A Exposed Fluid API partially addresses environment through Material Class [4.2.3] and Annex A Must comply with NACE MR0175 / ISO 15156 Service Life System Analysis 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

Gap Analysis – API Spec 6A Design Methods [4.3] API 6A currently uses ASME Sect VIII (2004) Elastic Analysis API 6A does not require a fatigue analysis Fatigue beyond scope of current document MMS NTL Requirements ASME Sect VIII, Div 2, Part 5 – elastic-plastic analysis with design margin based upon plastic collapse (structural instability) ASME Sect VIII, Div 3 – fatigue life analysis 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

Gap Analysis – API Spec 6A Closure Bolting [4.3.4] API 6A Sallow = 0.83 Sy at hydro test pressure ASME Div 3 Sallow = 0.55 Sy all working loads ASME Div 2 Sallow = 0.25 Sy all working loads Material Toughness [5.4.1] API 6A CVN ≥ 20 ft-lb avg ASME Div 3 CVN ≥ 30 ft-lb avg + KIc as specified QTC [5.7] API 6A part thickness but not required to exceed 5” ER ASME Div 3 equal to min forged Q&T thickness 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

Gap Analysis – API Spec 6A Surface NDE [7.4.2.2.8 and 7.4.2.2.9] Ferromagnetic materials API 6A and ASME Div 3 are the same if t ≥ 2 in. Non-ferromagnetic materials ASME requires < 10 rounded indications in 6 in.2 area Volumetric NDE [7.4.2.3.15] 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010

PER15K Report - SC6 Meeting 6/30/2010 Recommendations Affect on other SC6 documents will follow lead of 6A SC6, SC16, and SC17 form a collective Task Group to address this issue Options: Separate Spec or RP for HPHT equipment Annex for 6A for HPHT equipment Including additional inputs, verifications requirements, validation requirements unique to 6A equipment Address load monitoring and re-inspection requirements Need agreement on single “best” method to accomplish all the objectives 1/2/2019 PER15K Report - SC6 Meeting 6/30/2010
