Overview
For many years, the refining industry has used corrosion control documents (CCDs) and integrity operating windows (IOWs) to manage the integrity of fixed equipment and establish optimum operating ranges for specific equipment. Other types of processing facilities are now implementing similar workflows to improve inspection effectiveness and turnaround planning, and most importantly, minimize the risk of process leaks and unplanned shutdowns.
API RP 970, Corrosion Control Documents, provides recommendations on developing, implementing, and maintaining CCDs, which summarize a unit's process description and its corrosion circuits, including the damage mechanisms in each circuit, as well as startup and shutdown corrosion influences. API RP 584, Integrity Operating Windows, provides information and guidance on developing and implementing IOWs, which are sets of operating limits used to determine the different variables that could affect the integrity and reliability of a process unit.
This guide serves as a companion piece to Inspectioneering's webinar, Understanding the CCD/IOW Implementation Process, and has been developed to help inspectors, process engineers, site metallurgists, reliability engineers, and senior management understand the benefits that CCDs and IOWs bring to a mechanical integrity program. It also provides a 9-step process for the successful implementation of CCDs and IOWs at a facility.
