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.

Inspection of Coils with Common Headers in Process Heaters
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.

Improvements in the Engineering Assessment Process of Metal Loss in In-Line Inspections
This paper was presented at the PPIM Conference 2013 in Houston, Texas.

By: Ian Smith and Lisa Barkdull, Quest Integrity Group

Improvements in data processing make it possible for continual improvement in automated processing of ILI data. Automated processing is necessary to traverse the exceedingly large ILI data sets acquired today. The combination of automated processing and human expert involvement form the basis of the data analysis process.

Safely Operating Steam Reformers between Turnarounds: A Holistic Approach to Reliability and Maintenance
By: Thomas Fortinberry and Jim Widrig, Quest Integrity Group

As seen in the March/April 2013 issue of Inspectioneering Journal

In order to increase reliability and operate with a higher degree of confidence, it is increasingly important to incorporate a holistic approach to steam reformer reliability and maintenance programs. When using such an approach between turnarounds, operators should consider these essential elements:
• Preventative maintenance
• Reformer tube inspections
• Advanced engineering services
• Reformer tube life assessments
• Reformer performance monitoring surveys
• Infrared (IR) temperature correction software

Infrared (IR) Inspection Program for Fired Heater Mechanical Integrity
By: Tim Hill, Senior Consulting Engineer, Quest Integrity Group

As seen in the April 2013 issue of BIC Magazine

Infrared (IR) thermometry has been used for 40 years to monitor tube metal temperatures in refining and chemical furnaces. However, to capture the full capability of IR thermometry, a proven methodology is required to measure accurate temperatures in a repeatable process.

16-Inch InVista™ Tool Case Study: Navigating the Bends
By: Lilly Darnell,Senior Marketing Specialist, Quest Integrity Group

As seen in the December 2012 edition of Pipelines International

Quest Integrity Group recently performed a series of in-line inspections and fitness-for-service assessments for a client in Canada. The company utilized its recently developed single module 16-inch InVista™ inspection tool. One of the lines proved particularly challenging, as it contained 20 bends with a minimum bend size of 1.5D, and five take-offs – a challenge for tools, as the tool could go in any direction instead of straight.

Heavy-Duty Gas Turbine Hot-End Bearing Failure
By: Dr. Matthew Smillie, Consultant Engineer, Quest Integrity

As seen in the July-September 2012 issue of Energy Generation

The rotors of heavy-duty gas turbines are exposed to the heat of combustion during their operation. This thermal loading, in addition to the mechanical loading due to self-weight and rotation, provides a challenge to the designers of gas turbines when aiming for the reliability demanded by the commercial requirements of operation. This article briefly introduces the particular issues of bearings in heavy-duty gas turbines, and then reviews a case study of a gas turbine bearing that could no longer hold its load and the situation surrounding its failure.
