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.

New Technology Allows Access to Coils with Common Headers in the Process Industry
By: Rich Roberts, Vice President and General Manager, Quest Integrity Group
As seen in the Nov/Dec 2012 issue of Inspectioneering Journal
Various fired heater designs in refineries and chemical plants contain common headers (e.g. Arbor coil configurations, CCRs, etc.) as part of their overall serpentine coil design. Accessing the interior of individual coils through the common header is challenging; however, advanced engineering firms and mechanical decoking companies have developed unique common header snorkel delivery systems.
Recent Innovations in Pipeline Seam Weld Integrity Assessment
By Dr. Ted L. Anderson, Chief Technology Officer, Quest Integrity Group
As seen in the November 2012 issue of Pipeline & Gas Journal
There was much discussion during 2011 of the seam weld issue by various parties, including state and local government agencies, pipeline operators, industry organizations and consultants. However, in a number of cases the necessary technology already exists, so further R&D might result in reinventing the wheel.
Modern ILI of Subsea Pipelines and Risers: Capabilities for Challenging Projects
By: Mohammed Al-Hamad, Quest Integrity
This paper was presented at the October 2012 MENDT Conference in Bahrain.
Advances in ILI technologies now provide operators a range of inspection options in overcoming pipeline flow, configuration and previously restrictive environments.This paper will demonstrate solutions that have worked in typical offshore environments.
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.
Signal™ Fitness-For-Service Provides Cost-Saving Calculations
By: Devon Brendecke, Product Manager, Signal Fitness-For-Service
As seen in the August 2012 issue of BIC Magazine
Being able to rapidly assess damage uncovered during planned inspections is a major part of the success of fitness-for-service. Since every region of damage is unique, sometimes internally prepared spreadsheet calculations are insufficient to accurately assess a piece of equipment with damage. A comprehensive software program that automates many of the calculations can mean the difference between a timely return to service and extra shutdown time.

Benefits of Hydrotest Exemption and Tank Settlement Assessments
By: Brian D. Rose, Ph.D., P.E., Principal Consulting Engineer at Quest Integrity
As seen in the August 2012 edition of BIC Magazine
Advanced integrity assessments based on inspection results can demonstrate that tanks and their components are fit for continued service, allowing tank operators to often postpone repairs until the next shutdown, eliminate the need for repairs or be exempt from hydrostatic testing.
Overcoming Offshore Inspection Challenges
By: Lilly Darnell, Senior Marketing Specialist, Quest Integrity Group
As seen in the September 2012 issue of Pipelines International Magazine.
Offshore pipelines can be challenging to inspect due to limited launcher/receiver facilities or limited accessibility. Quest Integrity Group offers a solution for these historically difficult to inspect or unpiggable pipelines with its InVista™ in-line inspection tool.

Compressor Dovetail Remnant Life Assessment
By: Quinton Rowson – Quest Integrity Group
As published in Energy Generation Magazine Jan-Mar 2012
The case study below of a compressor dovetail remnant life assessment demonstrates the implications of small aerodynamic loads. It also explains the use of computational fluid dynamics and finite element analysis stress modelling in obtaining the remnant life of compressor blades. Remnant life assessment determines the remaining life of a component due to a time- or cycle dependent material deteriorating process, for example, creep or fatigue.
