PRDWise was developed by E2G to simplify the implementation and maintenance of Pressure Relief Device (PRD) Risk-Based Inspection (RBI) programs. PRDWise uses the same methodology outlined in API RP 581, Risk-Based Inspection Technology, 3rd edition. The API RP 581 PRD RBI methodology became available to users with the release of the second edition in 2008. However, issues were identified that could have potentially made implementation unsuccessful and/or very challenging. Solutions to these issues helped shape the PRDWise method. These issues and solutions are discussed in more detail in this article.
