Pioneering Research Using CorDEX Instruments’ Technology Aims to set new Integrity Management Standards
ABERDEEN, Scotland, September 7, 2011 /PRNewswire/ –
Research underway at the University of Aberdeen using an intrinsically
safe tool developed by CorDEX Instruments is set to provide a new model for
corrosion assessment to enhance oil and gas safety.
The aim of the research is to shed light on how corrosion develops
spatially on steel pipelines and vessels to improve replacement decisions
and integrity management. This type of corrosion research is breaking new
ground and will give deeper insights into the deterioration of oil and gas
Many existing failure models allow for the inclusion of one active
corrosion defect in the assessment. While these calculations can incorporate
variability in the engineering problem, they do not take into account the
effect of multiple areas of corrosion.
Dr Neill Renton, head of chemical engineering within the School of
Engineering says that the research provides new understanding of how the
spatial variability of corrosion can impact these systems.
He said: “The deterioration of assets through corrosion damage is a
critical problem for the industry. The determination of remaining pipeline
or equipment life and the ability to plan suitable maintenance and
inspection programmes has a key part to play. Spatial correlation between
areas of corrosion is not typically addressed in standard assessments. The
methodology we are developing will extend existing models and provide new
ones which can help engineers make timely decisions on replacement and
“Using CorDEX Instruments’ new UT5000 Intrinsically Safe Thickness Gauge
has been highly beneficial as it has allowed us to gain exact readings to
verify our research. The CorDEX CONNECT system provided accurate corrosion
analysis and the MultiECHO(TM) technology improved measurement on uneven
surfaces. It was crucial for us to have the most precise readings possible
to provide a robust foundation for us to base our findings on.
“This technology has much wider implications for the industry as the
ageing asset wave breaks. The intrinsically safe device allows for testing
during normal operations without the need for any hot-working. This could
allow testing on a much more regular basis than has been possible before,
giving us a greater ability to track corrosion over time. If a number of oil
and gas companies use the technology then there would be a dramatic
improvement in our understanding of deterioration with associated safety
The industry is increasing importance on monitoring and maintenance of
ageing assets. The HSE last year launched the KP4 initiative which provides
guidelines for the inspection and maintenance of ageing installations.
Tony Holliday, CEO of CorDEX Instruments said: “Safety and corrosion are
high up on the oil and gas agenda and we are excited to be involved in
research with the University of Aberdeen which will play a part in enhancing
industry procedures. Our equipment fits with what the sector seeks to do in
relation to ageing assets. Without the need to wait for shutdown to conduct
testing, it provides the opportunity for more comprehensive and regular
inspections to be carried out.”
The research into the spatial corrosion model is being carried out by
MSc student Ryan Maurice as part of his Subsea Engineering degree. The final
results of his dissertation will be submitted this month. It also forms part
of a wider research project on corrosion, funded by National Subsea Research
Institute (NSRI), which Dr Renton is conducting with Dr Srinivas Sriramula,
lecturer in safety and reliability.
Teeside headquartered CorDEX Instruments has a base in Aberdeen,
Scotland, and has a network of distributors across the USA, Europe and the
CorDEX is a leading manufacturer of intrinsically safe and non
destructive testing products for the oil and gas industry. For further

Interview opportunities will be available with Dr Neill Renton at 11am
on Wednesday 7th September at CorDEX Instruments’ stand 4E51.
Notes to Editors
About the UT5000
- The UT5000 is tested for Zone 1 IIC T4 hazardous areas, so no hot work permit is required. - Designed for rugged environments, an over-moulded body protects a 3.1" RGB TFT colour screen with backlight. The dual-element, 4MHz transducer is adjustable up to 10Hz with accuracy of +/- 0.05mm. - UT5000 accuracy is +/- 0.05mm, in both single point and continuous measurement mode, delivering unprecedented accuracy and flexibility to classified area NDT inspectors. - The tester features both single point and corrosion modes, allowing the user to identify specific points of thinning in a pipe wall. - Large, well-spaced buttons allow users ease of operation, even when wearing gloves. - The UT5000 is available through distributors worldwide. Additional accessories, including extra transducers, software and RFID tags, are also available
About CorDEX Connect
- CorDEX CONNECT is the first system to integrate RFID technology, reporting software and a handheld intrinsically safe tester to enable predictive maintenance for pipelines and fixed equipment in hazardous areas. - The UT5000 Ultrasonic Tester with CorDEX CONNECT uses RFID to tag every thickness measurement with a specific location, date and time. A proprietary software programme then collects and organizes the data, giving engineers a comprehensive view of the pipeline at any specific location. - With CorDEX CONNECT, those responsible for monitoring pipeline safety can use data collected by anyone in the field to create predictive maintenance programs. Using CorDEX CONNECT trend analysis capabilities, trouble spots can be identified from measurements taken over multiple visits. - Users can easily create printable charts and graphs, such as "thickness over time." Data also can be exported to Microsoft Excel or into a .csv file. - CorDEX CONNECT senses when the tester may be out of calibration, alerting the user to suspect readings. When the tool is sent for calibration, real-time tracking allows the user to track its transport and calibration status.
