Critical Spares - Who Needs Them and When?
By: Stephen Rowbotham, Quest Integrity NZL Ltd.

As seen in the Jan-March 2014 issue of Energy Generation Magazine

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.

Case Studies in the Application of Advanced Technology to Pipeline Flaw Assessment
By: Ted L. Anderson, Chief Technology Officer and Ian Smith, Senior Consulting Engineer at Quest Integrity

This paper was presented at the PPIM Conference in Houston, Texas February 2014

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.

Drain Piping Inspection at the Palo Verde Nuclear Generating Station
Arizona Public Services' Palo Verde Nuclear Plant located near Phoenix, Arizona contains a complex, interconnected network of waste drain piping between 3 large tanks in the chemical and volume control system making access for internal and external inspections difficult.

When Bad Things Happen to Good Pressure Vessels: A Story of Localized Metal Loss
By: Michael Turnquist, Consulting Engineer - Advanced Engineering, Quest Integrity Group

As seen in the Nov-Dec 2013 issue of Inspectioneering Journal

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.

High Resolution Ultrasonic In-Line Inspection for Non-Scrapable Pipelines
By: Saeed F. Farea, Saudi Aramco and Mohamed Al-Hamad, Quest Integrity

This paper was presented at the October 2013 Best Practices in Pipeline Operations & Integrity Management Conference in Bahrain

The Inspection Department at Saudi Aramco introduced several initiatives to address the challenge of ILI for non-scrapable pipelines and evaluated several NDT techniques. Among the validated technologies were several ILI tools that the department implemented as an effective methodology to maintain pipeline integrity.

Overcoming Heavy Bore Restrictions
By: Lilly Darnell, Senior Marketing Specialist

As seen in the September 2013 issue of Pipelines International

The pipeline projects department at a major oil transportation company in Canada planned to inspect a 6 inch sour gas pipeline with conventional in-line inspection (ILI) methods. However, it was determined that conventional ILI methods were not a viable option due to heavy tool damage on gauge-pig runs.

Optimising Inspection Planning and Asset Integrity Management using Fitness-for-Service Methods
By: Sean Norburn, Senior Consultant - Structural Integrity, Quest Integrity Group

As seen in the Australasian Welding Journal, Volume 58, 2013

The inspection of assets typically found in power and process plants is not only costly; it requires careful planning and preparation work. This article illustrates how Quest Integrity Group uses fitness-for-service methods such as API 579/ASME FFS-1 [1] and BS 7910:2005 [2] to optimise inspection programmes and minimise the amount of inspection required, therefore reducing down-time and the associated loss in revenue.

The Challenge of Inspection and Assessment of Critical Piping Systems in Chemical Plants
By: James R. Widrig, Senior Consulting Engineer, Quest Integrity Group

As seen in the Jul/Aug 2013 issue of Inspectioneering Journal

Inspection and fitness-for-service assessment of critical in-plant piping systems are a concern for the chemical industry. Many in-plant piping systems have historically been unpiggable due to their small diameters and the obstacles inherent in valves and bends, as well as diameter changes. However, many of these piping systems can be inspected with advanced smart pigging technology that provides 100% coverage of the internal and external pipe surfaces.

By: Rich Roberts, Quest Integrity Group

As seen in the May/June 2013 issue of Inspectioneering Journal

For more than a decade, the use of intelligent or smart pigs has become a standard practice when inspecting regular flanged coil configurations, which do not contain common headers. However, with new common header snorkel delivery systems, these particular heater designs are also able to be inspected using the same approach.

Beyond Unpiggable Inspections: Pipeline Attributes and the Challenges They Present to the ILI Process
By: Ron Maurier and Michael McGee, Quest Integrity Group

As seen in the June 2013 issue of Pipeline & Gas Journal

Today’s in-line inspection (ILI) technologies provide reliable solutions for inspecting pipelines once deemed unpiggable or difficult-to-inspect. Yet the tools are only one part of the solution. The fact remains that “unpiggable† pipeline challenges do not affect just the ILI tools – planning and managing the overall inspection project, and the complex variables involved, are critically important in delivering expectations in these challenging environments.
