Overview:

Mr. Henry is responsible for engineering consulting services in the areas of Pressure Relief, Heat Transfer, and Fluid Flow.  He is a specialist in the design, installation, sizing, and selection of PRDs and relieving systems, and has been the Chairman and Master Editor of the API Pressure Relieving System Subcommittee’s Task Force on API 520 for the last 23 years.  He conducts audits of pressure relieving systems to ensure compliance with OSHA, PSM legislation, and ASME, API, and DIERs Standards, Codes, and Publications.  He also teaches the official API Pressure Relieving Systems course.

Mr. Henry is actively involved in the development of technology for the API Risk-Based Inspection (RBI) methodology.  He was the lead investigator of the re-write of API 581, RBI Technology and is still active in the API 581 task force on risk-based inspection.  He is responsible for the development and implementation of RBI programs and chairs the software User group meetings for the API RBI software.  Mr. Henry has developed a rigorous consequence analysis model to assess the impact of loss of containment from refinery and petrochemical fixed equipment.  He also developed industry guidelines on performing risk-based assessments of process equipment, including PRDs, heat exchanger bundles, and fired heaters.  Mr. Henry is a certified instructor for the API 580/581 course on RBI.

Mr. Henry provides technical support and engineering consulting to all levels of refinery capital projects.  He is responsible for the preparation of purchase specifications, design reviews, and the development and validation of approved vendor lists.  He conducts project safety reviews for construction and pre-start-up phases of major capital projects.  His responsibilities include developing and maintaining engineering specifications in the pressure relief and heat transfer areas and providing overall coordination.
