Overview of API RP 584 - Integrity Operating Windows
API RP 584, Integrity Operating Windows, is a standard developed and published by the American Petroleum Institute (API). This standard is meant to explain the importance of, and help facility owners create, put into place, monitor, and maintain an Integrity Operating Window (IOW) program for each vulnerable unit and piece of equipment in their facility. The recommended practice was released in May of 2014, and a second edition has yet to have been released.
IOWs are incredibly important for a facility; having set limits for equipment operation can prevent excessive equipment degradation and unnecessary failures. API RP 584 doesn’t provide a specific list of IOW plans or the types of equipment on that might require and IOW. What it does do is provide the reader with the information they might need to identify what equipment of theirs might require an IOW and how best to create and implement and IOW for that equipment.
Specifically, this recommended practice includes information such as definitions of IOWs, the different types of IOWs, and terminology related to them. It also puts forth guidelines on creating, documenting, and implementing IOWs, and discusses the data and information that most useful in their creation. It talks about how to monitor and measure variables within existing IOWs and how to communicate when a limit has been breached. Finally it covers reviewing and updating existing IOW programs, and how to integrate these programs with other safety practices. Three Annexes are provided with samples and examples
This recommended practice also discusses topics such as Risk Based Inspection (RBI), management of change (MOC), process safety information (PSI), and training. But only insofar as they relate to IOWs.
