Joined Cameron Iron Works in 1981 and spent the next 25 years in the BOP and Wellhead manufacturers side of the business in various capacities from field service through country manager. Joined Chevron in 2006 as a Drill Site Manager in international shelf and deepwater Drilling and Completion operations. Presently in Chevrons Global Upstream Capability Group in Houston as a Subsea Well Intervention Advisor focused on well control equipment for surface and subsea operations. </p><p>1220 L Street, NW Washington, DC 20005-4070 www.api.org</p><p>Temp chart now has a classification up to 350f extreme. Basically there are three categories, Low, Operating, and Extreme. There is a class G designation to cover any elastomer above 350F and states the elastomer must undergo the same qualification test prior to being put in service. This was more of a clean up to align with 6A and NACE MRO-175 welding criteria. Minimum design criteria set for 16A equipment. Previously the 16A specification stated you test to the required cycles and parameters and just report the data. This meant if your equipment did not pass all you had to do is report it didnt pass and you could still qualify to 16A. Now there is a minimum criteria all equipment must pass to be qualified to 16A. *These classes were removed due to the work 17TR8 and API 6X are performing. The present design methods may not provide adequate detail for the proper design at these elevated pressure ranges. Thoughts on this are the present methods favor elastic/plastic design methods however the SMEs feel the increased forging sizes required for these pressure ranges may need to use fracture mechanic methods. Our representation 17TR8 is to monitor and assist in the development of the best path forward. *These classes were removed due to the work 17TR8 and API 6X are performing.

This would apply to annulars and ram preventersLooking at seal pressure required to maintain the seal as parameters change, i.e. packer wear, well bore conditions. Etc. Working with 17TR8 and API 6X to monitor any proposed change in design methods relating to 20, 25, &amp; 30k equipment. Additionally, the effects of external forces BOP equipment are subjected to understand how they may effect the performance. i.e. bending, tension, compression, hydrostatic forces. We have agreement on establishing controlled hardness of closure bolting. The main issue is what should the maximum hardness be, 34rc or 35rc? With the development of 16AR a need for more detailed product history was evident. *Change the drawing. *Operation TempC:200D:250E:275</p><p>Extreme Stays the same. *Fixed Bore Ram:Note: Strip 3000ft and 100ft Tool Joints needs to be revised-Remove the tool joints from requirements, keep 3000 ft, and ensure the testing procedures are aligned (appendix B), table 17. -</p><p>Hang-off:6-5/8 hang off qualification?-minimum is 5 </p><p>Locking and Sealing Mechanism:-for the connectors.-How to really test connectors and qualifications (Pressure testing, bending moments..etc)-LMRP Connector? Wellhead Connector? </p><p>VBR:-No change-Hangoff: remains as the reportable..tested to smallest and largest OD.</p><p>Temperature Verification:-Divide into sections-Low Temp 3 Cycles.-Normal Ops-Cont. High Temp-Extreme (define extreme as emergency)-Line up closures with the procedures. (procedures for high temp are not defined yet)</p><p>Shear:-Divide into two sections: Sealing and Non-Sealing, ensure alignment with procedures. -See Table 18 or PO-Remove PO..Table is for min. standards. </p><p>-CSR: Separate category, and report what the capabilities of the CSR is able to shear. (not for this section)</p><p>Packer Access:-Reference Table 17. </p><p>Annular BOP:-60 cycles and 3 Pressure TestChange Ram BOPs to do the same. </p><p>Hydraulic Connectors: -Review P1, P2, S2, S3-Develop generic tests to qualify for connectors, flush through list of tests examples. -Latch/Unlatch-Pressure cycle: Body and operating system-Tension/Compression-Combination Loading-Temperature-Hydrates??Need a small group: Eric Larson, Chris Johnson, Nick with cameron, Stress Eng., Shanks, </p><p>*</p></li></ul>
