Joint Integrity - Bolting Technology Application and Benefits

This paper builds upon our previously reported Bolted Joint Integrity Program at a North American upgrader plant with a capacity of 665 KBPD diluted bitumen feed and 300 KBPD production. [1]. The program outlined seven key components necessary to achieve zero leaks in bolted joints. However, issues can arise from incorrect torque application, whether it is over-torqued, under-torqued, or missed entirely, resulting in significant costs. This paper explores the benefits of digitizing the following areas within the plant: • Engineering and analysis. • Code and execution compliance. • Tracking, documentation, and Quality Assurance. • Implementation. Canadian Natural Resources Limited implemented commercial software, which integrates with smart tools (connected hardware) via Wi-Fi, smartphones, or onsite digital tablets to cloud storage and networks and/or computers. This system combines data with Canadian Natural company database, which maintains records for over 100,000 joints. Digital tools and software can enable real-time visibility and tracking of bolting activities, allowing for extensive data analysis of key performance measures. We found a problem being able to verify contractor compliance, especially after the fact, and implemented a tracking and verification program to correct the problem. (Applied to maintenance and turnarounds). Following implementation, plant staff can monitor and record the actual torque applied to each joint in real time using computers, smartphones, or digital tablets, facilitated by broad enhancements. This technology is applicable to all facilities and worksites including maintenance and manufacturing that use bolted joint assemblies. The paper presents the lessons, experience & challenges to save cost and document compliance.
