Subsea liquid hydrocarbon production systems operate on the seabed in 10,000 ft of water at locations far from shore. They are comprised of production wells, jumpers, manifolds, pipelines and risers to enable offshore production. As hydrocarbon production moves into even deeper water, the cost of surface production systems becomes prohibitively high. Intelligent subsea processing and safety systems are leading the way to developing cost-effective solutions that simultaneously satisfy governmental regulations while safely producing crude oil in ultra-deep water. Presented is Project Atlantis, an autonomous intelligent subsea production system that eliminates long distant tie-backs, addresses flow assurance issues while reducing field development and facility costs. The focus is a model-based procedure for the design and analysis of a subsea High Integrity Pressure Protection System (HIPPS). Offering an alternative to the conventional design requiring the use of pipelines rated to the well shut-in pressure, the installation of HIPPS with low pressure-rated pipelines downstream of its location enables considerable savings in the project CAPEX making the development of high-pressure-high-temperature (HPHT) wells with a long tieback cost-effective without compromising the safety. The proposed design procedure is based on a low-dimensional two-phase flow transient model to evaluate the effect of the HIPPS on the subsea architecture.
Dr. Matthew Franchek is the founding director of the University of Houston Subsea Engineering Program. He received his Ph. D. in Mechanical Engineering from Texas A&M University in 1991 and started his career at Purdue University as an assistant professor in Mechanical Engineering. He was promoted to an associate professor with tenure in 1997 and then to full professor in 2001. While at Purdue, he initiated and led two industry supported interdisciplinary -research programs: an Automotive Research Program and an Electro-Hydraulic Research Program. From 2002 to 2009 he served as Chair of Mechanical Engineering at UH while simultaneously initiating the UH Biomedical Engineering undergraduate program. After his term as Department Chair, Dr. Franchek worked with Houston area companies to create the nation's first subsea engineering program and is the founder of the Global Subsea University Alliance. His expertise is in model-based methods for diagnostics and control of aerospace, automotive, biomedical and energy systems. His current research program focuses on multiphase pipeline flow, artificial lift, blowout preventers and electrical power distribution. He has authored over 100 archival publications, and over 100 conference publications. He has served as the advisor to 25 doctoral students and 37 masters students.
