Abstract Details

2005, Master of Science, University of Akron, Mechanical Engineering.
In today’s petroleum refining industry, aging infrastructure is a primary concern when considering replacement costs and safe operation. As vessels, piping, and tankage age in service, they are subjected to various forms of degradation or damage that may eventually comprise structural integrity. An engineering or Fitness-For-Service (FFS) assessment is required to evaluate structural integrity and safely extend the life of damaged equipment. Guidelines for performing a FFS assessment have been documented in API RP 579. The goal of API 579 is to ensure the safety of plant personnel and the public while aging equipment continues to operate, provide technically sound Fitness-For-Service assessment procedures for various forms of damage, and help optimize maintenance and operation of existing facilities while enhancing long-term economic viability. The procedures in API 579 (2000 release) provide computational methods to assess flaws that are found in in-service equipment caused by various damage mechanisms. The focus of this study is to review the technical basis for the Fitness-For-Service assessment procedures for general and local metal loss. Extensive validation of these procedures along with additional development is presented. The conclusions of the study are recommended as the best practices to be included in future versions of API 579.
