Ninety Nine Diseases of Pressure Equipment in the Hydrocarbon Process IndustryNational Pressure Equipment ConferenceBanff, Alberta 10 February, 2005 John Reynolds Shell Global Solutions, US Houston, Texas What will I talk about this morning? What’s in the title (why the 99 Diseases)? Who should know about the 99 Diseases? How to use the 99 diseases to prepare RBI plans Establishing Integrity Operating Windows (IOW’s) to avoid the 99 Diseases Where to learn more about the 99 Diseases? Then we’ll cover a few of the 99 Diseases What are the 99 Diseases? General types of degradation mechanisms that can cause failure of pressure equipment, like: General and localized corrosion and erosion Environmentally caused cracking Metallurgical aging and degradation High temperature degradation and brittle fracture Mechanical cracking and damage Welding and fabrication flaws Anything that will cause materials of construction to degrade and possibly cause failure of pressure equipment in service Who should know about the Diseases? Not just materials and corrosion specialists, but also: Inspectors Operators Process and technology engineers RBI teams and PHA teams Project and equipment engineers Maintenance personnel Everyone that has a stake or role in preventing pressure equipment failures What do “others” need to know? Enough to help them recognize degradation issues and to seek help from materials and corrosion specialists, when necessary Enough to help them understand the importance of operating within the integrity operating windows (IOW’s) Enough to help them understand and assess when changes to equipment and/or process conditions might cause changes in types of degradation or changes in rates of degradation Why Spread the Knowledge? Because in many cases of equipment failure, the materials and corrosion engineer is the one person that “knew” what could happen and could have helped to prevent the incident; but was not in a position to do anything about it when it occ
