Digitalized Corrosion Control Documents for Improved Plant Reliability and Asset Integrity

Abstract Plant operators face increasingly complex challenges in managing the integrity of process units and assets given the immense amount of data that needs to be monitored and reviewed to ensure reliability. They also have a critical need to correlate and rationalize all the data and corrosion touch points to ensure and enhance mechanical integrity. Industry Recommended Practices, such as API(1) RP 970 - Corrosion Control Documents (CCD) and RP 584 - Integrity Operating Windows (IOW) provide a best practices framework to define principal mechanical integrity and degradation concerns, correlate multiple unit operational parameters such as process throughput, composition, key degradation parameters, damage mechanisms, metallurgy etc. To mitigate the immense complexity of different types of data and in-depth technical insights captured in a CCD, a digitalized CCD solution has been developed to provide a framework to easily identify and monitor the most critical aspects of process plant units, in terms of specific piping and equipment, key corrosion loops and damage mechanisms. This framework is designed to dynamically link to the process historian and Integrity Data Management Systems (IDMS) to monitor key process parameters and ensure operational integrity.
