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

Making the Most of Storage Tank Inspection Data
Thanks to constantly improving technology developments, inspection of atmospheric storage tanks has yielded better data which, when used as input, improves the accuracy of advanced assessment techniques. Coupling the improved inspection data with an advanced engineering assessment often means that tank operators are able to postpone repairs until the next shutdown, eliminate the need for repairs or be exempt from hydrostatic testing.

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.
Intelligent Pigging of an Unpiggable Gas Pipeline in Australia
Quest Integrity Group was approached by a client to inspect two sections of an unpiggable 14† high pressure gas pipeline in Australia. The line is over 40 years old and the client wished to evaluate its integrity so as to ensure safe operation for the remaining life of the affected facility. Quest Integrity utilized its InVista™ intelligent pigging technology to perform the inspection.
New Technology for Inspecting Critical In-Plant Piping Systems
Inspection and fitness-for-service (FFS) of critical in-plant piping systems remain an ongoing concern for the chemical industry. Recent failures in the US indicate that there is a present and severe risk in piping systems. Historically unpiggable in-plant piping can now be inspected with advanced smart pigging technology for complete ultrasonic inspection. High-resolution inspection data is analyzed to identify the locations and degree of corrosion and piping deformations. This article discusses current industry experience with the inspection and assessment of in-plant piping systems using advanced smart pigging technology.
Inspection Methodologies and Tradeoffs for Inspection of Unpiggable Pipelines
By: Dan Revelle, Manager Pipeline Services, Quest Integrity
This paper was presented at the November 2011 PPSA Conference in Aberdeen, Scotland.
Modern advances in inspection technologies now allow for inspection and assessment of these previously unpiggable pipelines providing today’s owner-operators a varied range of inspection options. By examining the results of various inspection methods and detailing how inspection data is used for assessment and asset management, we can understand how inspection data ties into the larger decision making process.
Advances in ILI Allow Assessing Unpiggable Pipelines

Advances in in-line inspection (ILI) tools and other inspection technology today allow for detailed assessment of unpiggable or difficult-to-pig pipelines.
Independent Validation of In-Line Inspection Performance Specifications
By: Dan Revelle, Quest Integrity
Understanding the capabilities of available in-line inspection tools is a key component of accurately managing and assessing pipeline integrity. Det Norske Veritas, USA, Inc. (DNV) was retained by a pipeline operator to provide support in evaluating the Quest Integrity InVista™ tool.
An Applied Approach to Crack Assessment
As seen in Pipeline & Gas Journal July 2011
Detecting and sizing flaws with advanced ultrasonic ILI tools, coupled with the API 579-2007 Fitness-for-Service approach to crack assessment, is a more efficient, reliable approach to determining pipeline FFS than hydro testing.
Ultrasonic In-line Inspection Technology and Fitness-for-Service Assessment for Non-Traditional Pipeline Inspection Applications
While many piping systems have historically been deemed unpiggable, advances in smart pigging and other inspection technology now allow for inspection of these lines.
Structural Integrity of Storage Tanks

Advanced integrity assessments based on inspection results can demonstrate that tanks and their components are fit for continued service. This allows tank operators to postpone tank repairs until the next shutdown, eliminate the need for repairs or be exempt from hydrostatic testing.
La Inspección de Tuberías con Dos Diámetros
Las fallas recientes de tuberías de alto perfil en los Estados Unidos, a focalizado el escrutinio de los entes reguladores en la evaluación y la gestión de la integridad en estos activos envejecidos, a través del mundo. Muchas tuberías viejas, incluyendo aquellas ubicadas en áreas de alta población, tienen geometrías tales como curvaturas de radio pequeño y cambios de diámetro, las cuales han llevado a clasificarlas como 'no inspeccionables'. La herramienta de inspección InVista™ de la empresa Quest Integrity Group es capaz de inspeccionar dichas tuberías y entregar información del 100% de la superficie de ellas, las cuales no pueden ser inspeccionadas por otras herramientas ILI.
Dual Diameter In-line Inspections for Pipelines
As seen in the November 2010 Issue of the PPSA Newsletter
Many older pipelines, including those in heavily populated areas, have geometries such as small radius bends and diameter changes which have traditionally classified them as unpiggable. The InVista™ tool from Quest Integrity Group inspects such pipelines and provides 100% overlapping data coverage of lines that were not able to be navigated by other pigs.
New Tool Inspects the Uninspectable
Saudi Aramco, in cooperation with American technology developer Quest Integrity, has successfully demonstrated a new flexible In-Line Inspection (ILI) tool designed to comprehensively inspect some of the company’s “non-scrapeable† pipelines, those that cannot be inspected by regular ILI tools.
