Trends in the Development of HPHT Design Guidelines

As the need for oil and gas equipment working in hotter and higher pressure environments continues to mount, the effort to come up with an adequate set of design, material, and validation practices continues to be challenging. The higher pressures, and therefore thicker wall sections, have pushed traditional thin-wall pressure vessel design practices to their theoretical limits, making design model assumptions increasingly inaccurate or overly conservative and too thick/complicated to fabricate. Manufacturing processes and material mechanical properties are also being pushed well beyond general practice to meet more stringent ductility requirements and to resist aggressive corrosion environments.

Historically, designers simply overdesigned the equipment to provide a robust product with liberal design margins to hopefully out-muscle any unforeseen or complicated set of loading conditions. However, for the newer HPHT oilfield equipment, the design challenge is shifting from uniform stress and “leaks” towards fatigue and fast fracture as the equipment is taxed by very high internal pressures, while increasing temperatures decrease material strength. The arduous effort is furthered muddied by a transition where old and new coexist, and the Industry continues to debate which best practices still relevant and where the lines of “demarcation” are between conventional and HPHT environs. Although this Rubicon will eventually have to be crossed, this presentation offers some insight into some simple tests to augment HPHT design practices.

Brian Skeels

Brian has 34 years experience in subsea completion and pipeline design and installation. 5 Years with Exxon Production Research Company working on Exxon’s famous SPS and UMC subsea systems, and the rest with FMC Technologies. As FMC’s Emerging Technology Director, he serves as a technical subsea advisor and strategic planning specialist for frontier technologies and new business opportunities. He efforts delve into HPHT, riserless light well intervention, ROV and remote robotics technology, and subsea spill containment programs for FMC Technologies, Schilling Robotics and FMC Technologies Offshore.

Brian has been part of API’s Upstream Standards for nearly 30 years and currently serves on API Subcommittee 17 executive committee, task group chairman for 17G on subsea intervention systems, co-chair for 17D on subsea tree and wellhead equipment, and chairs 17TR8 for HPHT equipment design and 17TR7 for subsea connector qualification task groups. Brian also participates on task groups 17A, 17C, 17H, 17O, 17V and 17W and served on several Industry and Professional Society conference program boards.
