9. 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 [ ]
Need to address system loads
Temperature rating [4.2.2]
Need higher temperature ratings – currently 250°F max
What temperature increments?

PER15K Report - SC6 Meeting 6/30/2010

11. 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

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
