Defect Assessment in Pipelines course

DESCRIPTION

Many oil and gas pipelines are at, or nearing, the end of their design life. Pipeline infrastructure, however, will need to perform for many more decades, as world demand for oil and gas is predicted to increase up to 2020. Many transmission pipelines are now over 40 years old – “middle aged” in pipeline terms. Even the best designed and maintained pipeline will become defective as it progresses through its design life.Operators, therefore, need to be aware of the effect these defects will have on their pipeline and, more importantly, be able to assess their significance in terms of the continuing integrity of the pipeline. The increasing use of high technology maintenance is helping pipeline owners to assess the condition of their lines. If these modern maintenance methods are combined with modern defect assessment methods, they can provide a very powerful and cost effective tool.

 

This course will present the latest defect assessment methods to pipeline engineers and managers. These methods will range from simple, quick assessment methods, to the more detailed “fitness for purpose” analysis. It is highly interactive and takes the form of lectures, workshops and case studies. It will cover methods available to assess the significance of defects detected in on-shore pipelines. Introduce simple analytical methods used to assess internal and external corrosion, dents and gouges, cracks, weld defects and fatigue. Include worked examples where attendees will calculate the significance of defects in pipelines and set intelligent pig inspection levels. What’s more, the course will be fully documented with all sides and related documents printed in a durable binder for reference during and after the course, providing an invaluable reference document.

 

Becoming a certified professional of defect assessment in pipelines helps you to differentiate yourself with demonstrated expertise and at the same time differentiate your company from competitors. This course will help you to obtain also, a holistic approach to defect assessment and to appreciates all aspects of the subject, including the latest defect assessment methods for pipeline engineers and managers. From simple, quick assessment, to the more detailed “fitness for purpose” analysis.
