Quest Integrity Group was recently contracted by the pipeline-integrity department of an offshore offloading facility to perform an ultrasonic in-line inspection of a 4 inch pipeline. By employing advanced engineering technology, the company was able to reduce the integrity department’s pipeline-integrity digs from 16 to three, saving time and money.

IR thermometry is an excellent diagnostic tool for detecting tube hot spots from internal fouling or non-uniform heat distribution in fired heaters, but to ensure the full capability of IR thermometry, operators should employ the right instruments for the job and implement a proven methodology to measure accurate temperatures in a repeatable process.

As published by the 2014 AIChE Annual Safety in Ammonia Plants and Related Facilities Symposium

A brittle fracture failure of several HK-40 tubes occured in the convection section of an ammonia plant feed gas heater. A failure analysis and API 579 Fitness-for-Service assessment were performed to determine the mode of failure and to determine the remaining life of the HK-40 tubes. This information provided the operator with a sound basis to evaluate the business and safety risks of continued operation until long-term repairs and system improvements could be implemented.

Historically, inspections for IFR Type B failures required a manned entry into the vessel. A confined space entry of this nature requires extensive planning and must be supported with product transfer, supplied air and an extensive lockout/tagout (LOTO) effort. However, a new solution utilizing remote digital video inspection (RDVI) techniques is now available for single seal tanks to alleviate the challenges associated with IFR Type B inspections.

Previously reformer outlet pigtails were considered standalone components with a nominal 100,000 hour lifespan. With improvements in reformer tube metallurgy and manufacture, pigtails are now seen as a weak link and often require replacement before the reformer tubes and manifolds. There is a strong incentive to improve pigtail reliability and lifespan, taking into account all the key factors, from design to material selection, metallurgy, grain size distribution, quality control or inspection techniques, and all the major focal points during the life cycle of these components.

Critical part assessment is an integral part of a facilities equipment integrity management system. As a plant ages and personnel changes, the existence of critical spares can become a mystery, especially if systems and policies are not in place to monitor and maintain the parts.

When it comes to evaluating flaws and other damage detected by ILI and other means, much of the pipeline industry still relies on simplified assessment methodologies that don’t take advantage of all data sources and improved understanding of failure mechanisms. This paper makes the case that adopting new technologies for flaw assessment is overdue, as these technological advances will be beneficial to the industry.

While there are many types of damage mechanisms that can occur in a piece of equipment, localized metal loss is one of the most common. If an inspection reveals that metal loss has occurred, many questions are raised: Can I continue operating? If so, for how long? Is a repair needed right away? Finding a solution to these questions can be difficult and costly. However, a solution can be reached through the application of finite element analysis (FEA) as outlined in API 579/ASME FFS-1 Fitness for Service1.
