Dacon’s Research and Development Team has recently started commercial commissioning of an 8” Magnetic Flux Leakage (MFL) Pipeline Inspection Tool that was designed and built at Dacon’s engineering facilities in Rayong, Thailand.
Dacon has over 15 years of experience in Pipeline Inspections with a primary focus on Ultrasonic technology which is utilized for its absolute measurement of corrosion and wall loss in pipelines.
MFL Pipeline Inspection technology gives a quantitative assessment of the amount of corrosion or metal loss in a pipeline and it is widely used for 3 main reasons:
It can be used for inspections in gas pipelines without the need to introduce any liquids.
The tool can gather data whilst travelling at high speeds thus minimizing pipeline downtime.
It is a mature and well proven technology that is less costly than advanced ultrasonic inspection tools.
Why Build MFL Pipeline Inspection Tools
The majority of offshore and transmission pipelines in the Asia region carry gas. Dacon will now be able to access a much larger section of the market than we are currently able to with Ultrasonic inspection tools alone.
MFL is still the most utilized pipeline inspection method in the oil and gas industry. Generally most pipelines are inspected every 5 years and by having MFL Inspection capability we can now provide our clients with MFL inspection data for “corrosion growth assessment” of their previously inspected pipelines as well as for new pipeline inspections.
When Will the New Tools Be Ready for Work?
A multinational Oil and Gas company approached Dacon with the request to build MFL tools so that they could meet the increasing demand to inspect their pipeline network.
Design and development of the tools began in early 2016 and the tools were ready for final testing and acceptance in December 2017. Trials and testing have been completed and the first commercial jobs are planned for 2018.
The Importance of Pipeline Inspections
It is critically important that pipelines are inspected on a regular basis to ensure that they are being operated in a safe and efficient manner. Any damage or corrosion in the pipeline may represent the danger of a leak or even explosion (these are called loss of containment events). Pipeline operators must be certain that they are operating their pipelines within safe parameters according to strict standards set in place by industry bodies and government regulators.
