Abstract
The CCD contained the following: * Process Description * Materials Selection Philosophy and Diagrams (MSDs) * Corrosion Loops (CLs) Descriptions and Diagrams (CLDs) * Corrosion Risk Assessment * Corrosion and Cracking Mitigation Strategies including o Chemicals Inhibition & Water Wash Injection o Materials Selection and Post-Weld Heat Treatment (PWHT) o Coatings Selection Plan o Cathodic Protection Plan * Corrosion Monitoring Strategies including o On-Stream Inspection (OSI) Plan o Intrusive Corrosion Monitoring o Process Fluid Sampling * Integrity Operating Windows (IOW) and Performance Measures In addition to above CCD elements, corrosion competencies, roles & responsibilities and work processes for major corrosion management (CM) tasks were reviewed and enhanced. Each parameter had an identifiable data sources (process tag number, laboratory data number, or condition monitoring location number), set maxima/minima limits, historical trends and possible risk of their exceedance.4 The CMDB tool ensures the timely, informed decision-making process to proactively manage corrosion by the following: * Displaying relevant parameters' deviations and its likely corrosion consequences * Listing actions to rectify these deviations and restore integrity * Sending automatic notifications to plant personnel, management and central engineering experts The development approach to deploy the different CMDBs is outlined in Figure 3 below: [...]it was necessary to develop a notification tool to alert plant personnel of exceedances to set limits. [...]the development and deployment of CMDBs allowed central engineering to focus on coming up with long term solutions to major corrosion challenges in the Company.
