It is not the intent of this document to provide a complete list of specific IOW’s or operating variables that might need IOW’s for the numerous types of hydrocarbon process units in the industry (though some generic examples are provided in the text and in Appendix A); but rather to provide the user with information and guidance on the work process for development and implementation of IOW’s to help strengthen the Mechanical Integrity (MI) program for each process unit. The scope of this standard includes: Definitions of IOW’s and related terminology, Creating and establishing IOW’s, Data and information typically needed to establish IOW’s, Descriptions of the various ty
