ABSTRACT

Digital integration of Corrosion and Chemical Management (CCM), Risk Based Inspection (RBI) and real-time process and corrosion monitoring are vital for the optimization of any Integrity Management System. "VERACITYTM" (referred hereafter as Software) has been developed to deliver this integration by linking RBI and CCM with real-time monitoring using COSASCO® wireless installations which provides a trend of the necessary corrosion and process data and correlation with other parameters.

This article presents how the integrated CCM and RBI modules of the software along with wireless installations are exploited to enable proactive, live, cost effective, and safe integrity management system.

INTRODUCTION

The process of digitalization is widely regarded as one of the last remaining cost-efficiency levers left following a sustained period of pressure to reduce operating costs and enhance efficiency. A new digital platform for seamlessly integrating Corrosion and Chemical Management (CCM) program with online real time monitoring is discussed in this article, refer Figure 1. The key objective is to establish full integration of real-time corrosion data with various parameters related to corrosion control. By adopting this approach, the following merits are attained:

• The RBI program can be continuously reviewed using the outcome of the integrated approach. Probability of Failures (PoF) used in the RBI study can then be subjected to continuous adjustment or confirmation based on the results of the real-time monitoring over a certain period.

• Continuous assessment of the effectiveness of the existing corrosion control measures and the impact of non-compliance activities on the integrity of the system is determined through the real-time data and inspection.

• Establishment of a rigorous Integrity Operating Window (IOW) based on actual data and its correlation with influential process and corrosion control parameters.

• Optimization of resources used for inspection activities, fluid samplings and the volume of chemicals injected or changed out as part of the corrosion control program.

• Establishment of better correlations which improve the delivery of the above objectives with higher accuracy.
